ATTORNEY United States Patent O 3,162 959 LIGHT TRNSMSSION ITELLIGENCE DESPLAY- ING AND RESPNSE RECORDING MACH-INE A Myron Woolman, 2306 38th St. NW., Washington 7, DC. Filed Dec. 2, 1960, Ser. No. 73,296 41 Claims. (Cl. 35-9) This invention pertains to a machine and modifications thereof for teaching by displaying a programmed sequence of intelligence or information through a light transmitting material and for recording upon a blank web of material responses of the operator of the machine for the purpose of training and education etc. The uses of this invention fall generally into the categories of teaching machines and record keeping machines.

In relation to the first use of the machine, i.e., the teaching function, it is the primary object of this invention to provide a teaching machine which is an inexpensive and simple compact unit which may be used in conjunction with properly programmed sequences of learing material to quickly teach a student learner necessary names, locations, functions and relationships within a given 'field of study as well as to equip him with the necessary concepts for manipulating material in that field to useful ends.

This object is accomplished by utilizing in the present machine information and interrogatory material which is so sequenced through psychological planning that the student must follow an effective learning procedure in using the machine in accordance with instructions.

Modern technology with its emphasis on technical skill requires more eicient teaching techniques. The use of machines to facilitate the learning processes promises to provide higher rates of learning, increased understanding and greater economy in the teaching of information yand skills. Also, the learner is freed to learn at his own rate of speed rather than to maintain the pace set by his class or instructor. Due to the fact that individual students vary in the amount of material they can learn in a given period of time where students are grouped, as in the typical classroom, faster learners must reduce their pace, while slower learners must proceed at higher rates of speed than is best for their learning eiciency. This diiculty is overcome by the use of the present individual machines which free each student to move through the sequence of lessons at his own rate of speed providing he meets a designated performance standard such as 90% or higher on the material learned to that point.

It is, therefore, another purpose of this invention to provide a teaching machine which may be economically provided for each of the students in particular classes of study so that each student may progress through the material at a rate of learning compatible with his experience, capacity and interest. Thus, the more well endowed students will be permitted to move ahead to more advanced materials while the less well endowed students or less experienced students will have a greater opportunity to absorb learning information in relationship to their capacities, backgrounds and demonstrated competence.

It is another purpose to provide a teaching machine by which the learners perceptual eld is restricted at any one time to the amount and kind of material designed or programmed to facilitate student learning. This machine permits the presentation of learning materials in small readily digestable amounts as opposed to lecture and text book presentation which do not control the factor of the size of the perceptual field. This material is generally presented in one of two manners; presentation of information to be comprehended followed by interrogatory presentations which require the student to respond in recorded form.

In present classrooms a great part of the teaching time 3,l62,959 Patented Bec. 29, 1964 ICC is directed to the verbal presentation of information by the teacher.y The students are largely passive receivers of information. In a machine teaching program each student actively responds in recorded form as much as two times eachl minute. Each student is successively assimilating and actively responding. As the response activity of the learner is an important determinant of learning, this process facilitates understanding of the material presented while freeing the teacher from the chore of verbalizing essentially the same information to class after class. This reduction in the chore of verbalization permits the teacher to concentrate on improving weaker students, developing new exercises and extending the range of student understanding.

It is, therefore, another object of this invention to provide a teaching device for individual student use which will free the instructors from the necessity of constant presentation of new material so as to provide the instructors with additional time and energy to assist and support thelearning of individual students, particularly weaker students.

It is also a function of this invention to provide a teaching machine which will allow responses to various interrogatory stimuli to be recorded upon a blank web of writing material and then to have these responses immediately compared to the programmatically correct answer which is also integrated into the programmed sequence of interrogations so that the student has the benefit of immediately knowing whether or not his response to the question propounded in the interrogatory phase is corrector incorrect. This immediate feedback provides the opportunity to compare answers with the programmatically correct answers. Informational feedback is one of the important aforementioned determinants of the learning process and has been shovm to improve learning.

In accordance with the invention the programmed sequence of information `and interrogatories is recorded on photographic ilm or upon a re-usable web of paper or like material. This intelligence is transmitted by a light source onto the undersurface of a blank writing web upon which the student yrecords his responses to such intelligence transmitted therethrough. The blank web is arranged over a light transmitting intelligence viewer plate which serves as a writing surface. In this way a programmed sequence of interrogatories may be completed by the student learner as if he were reading printed materials and answering questions by recording responses in order to learn the particular presented subject matter. However, the necessary printing costs, inherent in the prior art due to the fact that the printed web of material onto which the student writes his answer is not re-usable, are eliminated due to the fact that the student only writes upon a blank web of material rather than the web of material containing the intelligence itself.

The prior art in teaching machines shows that the intelligence or interrogatories `are written upon a sheet of paper upon which the student records his responses and therefore must be thrown away at the end of each using and therefore necessarily incurs greater cost than does the present re-usable programmed sequence of material. These teaching machines are represented by U.S. patents to Skinner 2,846,779 and Fernbach 2,837,839.

Some of the prior teaching machines overcome the difficulty of having to print all of the intelligence upon a web which is then discarded due to the fact that the student learners responses were recorded thereupon by providing devices such as shown in Mills 2,401,434 in which the answers are indicated by a number of buttons which are operated to select a multiple choice answer. y

The difficulty with this type of machine is that the student cannot construct meaningful written answers in his own words; multiple choice options restrict student re'- sponses to those provided by the programmer and are necessarily limited in scope and numbers.

Theuse o f such-operator buttons for recording re'- sponses to questions posed or information given rather than recording the desired answerV directly on the webV gives rise to asurrogate response, i.e., a response which is a substitute for the real answer. The use of such surrogate responses requires the student learner to give some answer other than the one which is actually called for and produces a situation in which responses are artiiicial rather than organic to the materials being learned.

Where surrogates are written, i.e., numerals or symbols, and are used to relate the question and answer parts of a teaching interrogatory; the symbols become surrogate responses which substitute for the true response and Vas the student Writes the surrogate symbol the learning o f the true response isV less eicient as the final action of the learner relates to the substitute or surrogate response and adds an additional step in which the surrogated and basically meaningless response is substituted for the actual response. V Y

Therefore, it is another object to presenta teaching machine` by which the respondent may answer questions meaningfully within the image of the questions themselves, so that the relationship is intrinsic and the learners answer is organic to the question and does not involve the distraction of a surrogate response. Thus, itxis possible by the present machine to present intelligence and information in the form of sentences and paragraphs of Written material in which certain terms, symbols and forms 'are omittedy from the material thereby creating blanks. This usage is particularly vital for such purposes as labeling the components of a diagram or picture shown on the intelligence.

The student then responds directly on the web and completes the diagram or sentence in accordance with his own skills and knowledges. He thus constructs the answer by inserting his own terms, symbols or drawings. This material is on Vthe web and may be used to evaluate the students progress and diagnose his weaknesses. As 'the studentV is constructing his ownv answers, sources of confusion are revealed by the student himself in contrast with multiple choice methods in which the students possible responses are assigned by others. Thus more sensitive and penetrating diagnostic techniques may be used to locate student diculties where the student is freed to construct his own responses and write them directly on theweb. A

It is, also, an object of this invention vto provide control over the level of learning so that the weaknesses of each student may b e corrected by having the student repeat all or part of the sequences of the material covered when performance evaluations `showI that his comprehension of the material has dropped below a prescribedstandard This object is readily accomplished by providing a machine in which parts of scientifically sequenced learning material may be reused by students where performance standards `have not been met.

Another very obvious advantage is that these programmed sequences can be duplicated on film very inexpensively and therefore provide a greaterV numberA of students with rse benefit of the vimpr-wed teaching tecanique resultant from the present invention at a cost which every school system or national government could afford for its students. This particular advantage' would have merit not only in this country but also in many. of Ythe underdeveloped countries where lack of educationis one of the major factors contributing to lack of progress and political instability.

In the interrogatory step of the programmed sequence of teaching materials, supra, it is deemed essential that the machine be capable of allowing the student learner to write his answer to the interrogatory upon the blank writing web so that for all practical purposes it appears that he is writing within the printed material when making his responses. Also in connection with the interrogatory step, the programmed sequence of teaching material may have the programmatically correct answer to the question set forth on the sequence in such a manner that the student must operate the machine in order to View the answer to the question and that by so operating the machine he advances his own answer into the machine so that the teaching machine is virtually cheat-free.

It. is, therefore, another object of this inventionrto provide a teaching machine which allows. the student to record an answer Ato a question propounded to and then View the programmatica'll'y correct answer` after his own answer to the question has been reeledinto the inachiner so that heV cannot change the same. This'l'object of the inventionallows the teaching machine Vto utilize eifectively one of the very valuable determinants of the teaching process, i.e., exposure to the correct answer to a question immediately after writing an answer` toy that question so that the student is either lcorrected by the program'- matically correct answer sov that he does not carry his error forward in his future learning, or his response is psychologically reinforced when his answer corresponds to the programmatically correct answer. A

It another object of this inventionto provide a teaching machine of the type described which is particularly adapted to the purpose of having the respondent respond to intelligence or information displayedrby the machine by setting forth his responses thereto by the use of a typewriter or other keyboar'dztype of printer. It is also,l a further specific object ofv this invention to provide a teaching machine of the type adapted to utilize the necessary determinants ofthe teaching process for teaching the respondent or `student learner operating such machine to operate this type of equipment with a higher degree of skill and to accomplish this degree of skill in fa shorter period of time than is now possible by present teaching techniques. Keyboard devices as here referred to are intended to c'o've'r any digital pressure operated devices such as, pianos, organs, typewriters, stenotyping machines, Vliriotype kmachines, IBMV machines and card operatingV machinery,r

- varityping machines, teletype machines, etc.

The use of the present machines for such purposes-as record keeping and the like is easily accomplished by replacing the Vprogrammed sequence o'i material with the outlines. of various forms to be completedf Such a use of the present machine may be illustrated by using a photographic copy of a standard W-2 income tait form for the employees in an industrial organization. Such a photographic copy may be produced by including within the projector means a camera means which will allow Vthe standard form to be light recorded upon the photographic sensitive filming, which in turn may be used to shadow transmit the form image. VT he form when recorded upon the photographic hlm would be proiected by means of a photographic projector onto the undersurface of the blank writing web of material and the informationnece'ssary to be recorded upon those forms then written directly upon the blank web of material of the positions corresponding to the blanks on the image form. For large'numbers of employees in such an organization all of the information required onv thesekforms couldV easily be storedin a relatively few number of rolls of blank material with'- out all of the -unnecessary printing and extra paper being present in the tiles in which this information is stored.V To obtain information on an employees form it would only be necessary to re-install the image of the proper formin the machine and then select the proper reel' frame number to s'ee what information is recorded for a particular employee. It is here pointed out that the previous example is exemplary only and there would, of course, be an inlinite number of possibilities as to the types of forms Vwhich could be set forth in this` manner S and the information to be filled in through recording upon a blank writing web.

It is a particular object of this invention to provide a recording machine and system whereby it is unnecessary to store recorded material upon forms for each of the entries represented by the information required by said forms.

It is a further object of this invention to provide a keyboard variation of the aforementioned recording machine which is used with specially programmed forms in response to which the respondent operator records entries called for by the form upon a specially designed blank sheet. n

Thus the keyboard variation of the present machine may be employed for a teaching function or for a record keeping function or for a keyboard skill teaching function.

These and other objects and advantages of this invention will become apparent from the following description and claims. In the accompanying drawings which illustrate by way of example various embodiments of the present invention:

Fundamental Teaching Machine Referring now to the drawings for a detailed description of the teaching machine, FIGURE l shows a portable and manually operated teaching machine. A compact housing structure lil is provided for enclosing the essential elements necessary for the operation of the teaching machine. One of these elements consists o-f a single frame intelligence projector I2 which may be converted to a moving type projector by means mentioned hereafter. This photographic or intelligence projector is arranged in the housing in an opening and is retractable for changing the photographic lm by means of the handle I4. The image produced by the projector I2 is reflected from a reflecting surface I6 onto the undersurface of `an information view plate I8 which is retained immediately under aperture 2) by brackets 22. The brackets 22 are of a construction which will allow the removal of the web along one side thereof. This information viewer plate 1S may be constructed of any material which has the characteristic of being transparent to light rays a sufficient degree so that line images presented by the projected beam are not diffused or distorted by the viewer plate. Such substances as clear plastic, glass, or natural crystalline substances meet this requirement.

Brackets 22 are so placed with respect to the undersurface of the inclined writing surface 24 of the housing structure I@ so that a blank web of writing material 26 may pass between the information viewer plate 18 and the undersurface of the inclined writing surface 24. This blank web may be constructed from any recording material such `as paper, plasticized fiber, plastic or the like.

The blank web of writing material is unrolled from reel 28 onto reel 34B. This latter reel 30 is integrally connected by one end thereof to a mechanical gearing system such as apa'wl and ratchet wheel arrangement or a rack `and pinion gearing system or the like. For purposes of illustration a pawl and ratchet wheel arrangement 32 is shown in FIGURE 1. The pawl 34 is spring biased outwardly and is pivotally connected by a pivotal connection 36 to a lever arm 33 which is rigidly connected to the flange or reel 3Q. The ratchet wheel has internally positioned teeth and is rotatably mounted upon its center axis with respect to the inside surface of housing structure It) and its axis is aligned with theiaxis of reel 30.

This pawl and ratchet wheel mechanical connection means is motivated by a rack and pinion arrangement 42. The pinion of gearing system 42 is integral with the ratchet wheel 37 and may be cut from the same piece of material so that the pinion gearing is on the outer edge of the wheel and the ratchet teeth are on the inside of the wheel. The rack 44 is positioned to slide upwardly and downwardly parallel with the topmost surface of the inclined writing surface 24. This rack is provided with an operator handle 46 for manual operation of the mechanism by the student learner.

Connected integrally with rack 44 Iis an information restricter plate 48 which is generally rectangular in configuration and has an information viewing opening 5l) positioned therein and also is provided with a lower answer restricting portion 52.

When the information restricter plate 48 is in the posi- 7 tion shown in FIGURE l the student learner may view the/information which is projected from the projector 12, reiiected from surface 16, onto the undersurface of Vihforination viewer plate 1S and 4through writing webV 26. This information is seen by the student through the information viewing opening Si) and he may then record his responses to the blanks in the material so projected upon the writing web. The student then is ready to move to the next frame of sequenced material,l however, he ist has an opportunity to View the programmatically "correct answerY to the interrogatoriesposed. The answer to the interrogatories may be transcribed on the lower portion of the frame in the photographed sequence of material on which the interrog'atory is also transcribed. This answer is hidden from the student learners View by information restricting portion 52. By moving the operator handle 4'6 upwardly the ratchet mechanism is caused to positively drive the blank writing web reel 3? by means Vof the rack and pinion mechanism 42. As the student then 'pushes the operator handle upwardly across the inclined writing surface 24, the portion of the blank writing web upon which he has set forth his answer to the interrogatory posed is reele'd onto the upper reel 35), thus preventing the student from changing his answer. As he moves the plate upwardly the information restricting portion 52 also moves upwardly and thus uncovers the programmatically correct answer which was restricted from his vision thereby. On the return motion of the information restricter plate 4S a portion thereof is caused to operate a contact 54 of switch 56 which actuat'e's pro'- jector 12 to advance theprogrammed sequence of material to the next frame. As lthe sequence of programmed material is presented to the 'student it may become necessary to show the student a sequence 'of 'frames in a moving frame manner so that motion of objects or a series of changes in a process may be presented. For this purpose the photographic iiim sequence itself may be marked in some manner so that when the marked portions of the hlm contacts a member within projector 12 theprojector is caused toV operate automatically until the required sequence of frames has been shown and then is reverted to frame sequence operation. By having .projector 12 op- 8 and a sprocket wheel contacting these holes to move the web by the wheel.

Itrfwill be noted that the teaching machine shown in FIGURE l which is battery powered, and entirely portable is particularly advantageous for use in underdeveloped countries wherein electric power is as yet largely unavailable. Y Y Y Y It is also to be noted that the information restricting plate 48 may be formed in any configuration with respect to the informationv viewing vplate 18 and the inclined writing surf-ace 24 so that a suitable and comfortable writing surface may be presented for the student and the blank writing web 26 may be presented to the student at the upper most surface of the inclined writing surface 24 rather than at a lower position as shown. The top plan view of the inclined writing surface 24 will be further discussed in relation to FIGURES 5 and 6.

An alternate construction of the basicV components of the fundamental teaching machinershown in FIGURE l is thatarrangement'illustrated in FIGURE la. 1n this arrangement a light source S propagates light (illustrated by arrows) 4up'on'the blank writing web 2d. As the student records'his responses thereupon the image of these responses is shadow Yor opaque transmitted bythe light through a suitable optical arrangement 62.'

Included within this optical arrangement is a projector which projects the images of the programmedrmaterials.

The images of the students responses and the presented material are combined within the arrangement 62 and projected o'nto the undersurface of the viewer plate 18. Thus by properly positioning his writing upon the writing web 26 the student may view through plate 18 his responses correctly integrated with the stimulus presented. Arrangement 62 has 'a connected switch 59, as does projector 12 of FIGURE 1. Such a Vcombination of ima-ges may be accomplished by a standard type opaque projection device in combination with a shadow transmitting i web or -tilm such as shown in US. Patent 2,553,903, to

era'te only after the information restricting plate '48 has been returned to rest position the interrogatory of the next frame is not viewable by the student so that he might have time to change his 'answer or to :see the answer Ito 'the next 4interrogatory before the answer restricting .portion 52 covers that portion of the information Viewing 'plate 18 through which the answer to ysuch interrogatories is transmitted.

The projector of the teaching machine shown in FIG- URE 1 is designed to b e battery powered so vthat it is an entirely portable unit. The batteries are situated within projector 12 Vso 'that they may be changed whenever neceslsary at the 'same time the film is being placed within projector 12. Projector 12 may be of any size and for very compact arrangements should use 8 mm. `nlm ror less, e.g. micro film sizes. A ny light propagation 'source control means which is adapted `'to controlling ythe light source -for presentation `of intelligence may be used; e.g. video-'tape operated camera projectors. Also, closed or Vopen TV circuits could be used to roperate such Vprojectors.

The housing 1li may be provided with an opening arrangement so that the blank writing web 26 may be 'changed when necessary and taken out for'evaluation purpos'es. Such an opening arrangement maybe provided by hinging a portion of the housing with a'hing'e snchas S8 and then causing the hinged portion to be pivotal about the hinge by lifting a handle 60. The reels of web material may be arranged within the housing 16` for easy installation and removal, such as a cartridge-type reel which may be 'self threaded across the information viewer plate. Such threading may be easily'accomplished by providing web tracks and sprocket holes within the web Dufour, FIGURE. 4. The writing web 26 corresponds to element `5, while the arrangement 62 corresponds to elements 12, 13, 14.

The components of this alternate construction may be housed in a suitable housing 63 such as V10 of FIGURE 1 and the construction presents many of the same advantages as does the macln'ncof that ligure. Housing may have a hinge means '64 for opening the same 'and a handle 65 as in 'FIGURE `1. Arsimilar information restrictcr plate '66 is slide'ably' positioned on the upper portion of the housing and has 'a like `Iinforrriation restricting portion 57 amxed to the lower part thereof. The rack and pinion arrangement '68 operates the feed reelV for Writing web 25 Vthrough a belt 69, as yFIGlRi 2. Y The -light source S and the opaque projector land intelligence 'presenting arrangement 62 are connected to va common electric supply E. s

Modified Fundamental Teaching Machine `Referring .to FGURE 2, rthe teaching machine shown therein vis a variation of the 4teaching machine of -FIG- URE 1 in that the intelligence or 'information of the programmed sequence of material is recorded upon an `information web which vis positioned by rollers r7-2i-to slide across the surface of information viewer plate 74.

The blank writing web '76 is positioned by means of rollers 78 with respect tothe information viewer plate 'so Vthat'the student learners 'responses may be recorded upon the writing web 76 in response to the interrogatories posed bythe information lrecorded lupon the infomation Vweb 70. A light source 82 is 'providedimmediately below the information viewer plate '74 so that the Vintelligence recorded upon web mmay betra'nsmitted through the blank'writingweb into the viewof the student learner. It is to 'be noted that the information web 7i) maybe positioned on either side ot the information lviewer 'plate 7 4.

p n ieaese The blank writing web '76 is designed to be unreeled from reel 84 onto reel 86 whereas the infomation web 70 is designed to be unreeled from reel 88 onto reel 9i). Both reels 86 and 99 may be driven in much the same manner as is shown in FIGURE 1, i.e., ratchet and pawl mechanisms or by comparable mechanical linkages so that they are powered to reel in their respective Webs either at the same rate or at differential rates. Information restricter plate 92 is provided which is connected by a spring linkage system (not shown) to answer restricting plate 94 so that as plate 92 is slid downwardly plate 94 is iirst moved into its covering position. The information restricter plate is mounted within guides 96 for reciprocable movement and is provided with an operator handle 98 for reciprocating the same. The answer restricting plate 94 is positioned on the undersurface of information viewing plate 74 so that the student will not be hindered by having a member protruding from the inclined writing surface Sti.

The driving mechanism for the two reels 86 and 90 is a rack and pinion gearing system 160. Rack 102 is integrally connected with a portion of the information restricter plate so that upon operation of the handle operator 98 rack 102 is caused to move over the teeth of pinion gear 104 which is rotatably mounted within the machine housing. A cable drum 106 is provided on one side of the pinion gear 104 so that power transmission cables 168 and 11G may be mounted thereupon. Cable 108 is asingle loop pulley cable having the other end wound about a pulley 112 which is rotatably mounted within the machine housing. On the inner edge of pulley 112 are ratchet teeth 114 which provide reaction surfaces for the pawl 116 which is pivotally mounted and outwardly spring biased upon the flange of reel 86 so that as the rack 102 is moved across the pinion teeth of pinion gear 104 the power cable 108 is moved so as .to cause the reel 86 to wind up the web of material 76. The mechanism of reel 90 works in the same manner as does the mechanism described for reel 86. Except that reel 90 reels the information web 70 onto the reel during the return motion of the rack 162 which action is provided by a double loop cable 11G. Thus, new information is not brought into students vision until he has completed the answer to the interrogatory posed by the previous frame in the sequence of material and has had an opportunity to view the programmatical answer by sliding the n answer restricting plate 94 upwardly which simultaneously reels his recorded response to the information under the information restricting plate 92.

A similar hinged opening as in FIGURE l may be provided in the machine housing as shown by hinge 118 and handle 126. This machine has many of the advantages that the teaching machine of FIGURE 1 presents in that it is compact, economically manufactured, portable, and allows reusable Webs of sequenced programmed materials to be used interchangeably in many machines, and also presents the factor of being less expensive to produce in that a compact lm projector is not required for operation of the machine so that all that is necessary is a source of electrical power for operation of the light source 82, such as a battery source 83. Also as no photographic film is required for the machines operation as the pro- Y gramrned sequence of material may be printed upon a web of such material as paper and reused so as to effect the economic savings inherent in the use of the present machine.

It should be noted that the reel supports in all of these teaching machines may be spring biased so that the reels of writing webs or information webs may be easily removed and replaced within the machine.

As an alternative to using a disposable web of Writing material for response recordation an erasable endless belt 122 may be provided as shown diagrammatically in FIG- URE 2a.

The belt consists of two layers and is supported by rollers 123 and 124. The outer layer 125 is a light transmitting substance of Celluloid or other plastic. The inner belt 126 is constructed of similar material but has strips of wax or petroleum compounds deposited thereon so that the student when he presses a stylus downwardly upon the outer layer presses the same into adhering contact `with the waxed portions and allows the student to view his responses as impressions. As the student uses the machine with this endless belt included therein the two belts are separated by a wedge 127 from their adhering contact to thereby prepare them for later use. The wax is applied in strips where it is opaque but may be continuous if it is light transmitting.

This alternative, of course, does not permit a permanent record of the responses so that the use is most effective when restricted to students who are capable of progressing through the program unaided and unchecked.

Automatic T eac/ting il/Iachne Variation Referring now to FIGURE 3, the teaching machine shown therein is designed to have included in the mechanism an automatic powering means for the blank writ ing web reel and is also equipped to have sequential op eration of the projector and to have included audio equip( ment for giving auditory instructions and information to the student learner. A desk type housing 131B is provided in which is contained a photographic projector 132, auditory equipment 134, a motor 136 for powering the blank writing web reel 138, and a synchronizing'unit 14@ which also functions as the power intake and distribution device. As internal mounting means 142 may be provided for housing the auditory equipment 134 and the motor 136. The auditory equipment is provided with a loudspeaker 144 mounted within the housing 130.

An information viewing plate 146 is provided on the undersurface of the inclined writing'surface 148 of the housing structure 136 and is positioned within opening 1511 so that blank writing web 152 may be reeled across the upper surface of the information view plate 146. The information viewer plate is supported within the housing 136 by brackets 154 which have inclined surfaces 156 for slidably engaging the blank web of writing material 152. The blank web is unreeled from reel 158 onto previously mentioned power driven reel 138 which is powered from motor 136 through power chain or belt 159.

An information restricting plate 160 is positioned within guides 162 upon the inclined writing surface 148 and along the opposite edges thereof are a pair of linkage rods 164 slidably mounted which connect the information viewer plate with the answer restricting plate 166 which is supported for slidable movement in a bracket 168. The linkage is slidably mounted upon either the opposite edges of the information restricting plate or of the answer restricting plate. After the student has recorded his responses upon the blank writing web 152 in response to the interrogatories posed by the image shown through the information viewer plate 146 by means of the photographic projector 132, he then slides the restricter plate downwardly in its guides 162 by means of a handle operator 176". The linkage rods 1,64 are arranged to slide in slots in either side of the information viewer plate 166. Abutments 172 are provided for the slots on either side of the information viewer plate 161i and are contacted by the pivot pins of the links 164. The reciprocal motion is transferred by means of the linkage pair to the answer restricting plate 166, and it is thereby moved downwardly. Immediately after the downward motion of the answer restricting plate has begun switch 174 is actuated by the plate and this then causes the blank writing web which has been written upon by the student and which is now under the information restricting plate to be reeled upon power driven wheel 138 by means of an electrical signal switched on by 174 traveling through lassociated conductor 176 through the synchronous unit 140 and the power transmission line 178 to the motor 136. The student equipment'134 and 144A are caused to operate.

then may view the answer to the question which he has just answered in the answer Viewing portion of lthe information viewer plater146. Upon returning'therin formation viewer plate 16.0 to its upwardrnost position and also continuing the motion until the answer viewing plate has covered the answer portion of the viewer plate the switch 174 is again actuated and the signal is carried to synchronous unit 14)v which then operates the projector 13.2 for advancing the programmed sequence to the next frame of material. In this modiication if the instructions. and information given to the student learner require auditory'signals at a proper frame or frames in the photographic sequence. 'a marlg upon that frame or frames may trigger an electrical response through the synchronous unit 140 sothat the auditory This auditory signal may either come from an independent source contained in housing 134 or may be a sound track upon the lrn used.

It is also to be noted that if a movie type sequenceV of frames is desired to be shown a suitable mark upon the sequence of materials may trigger an electrical circuit to cause the projector 13 2 to go into motion type movement.

It should be here pointed out that the instant teaching machine is cheat-free7 in that the student learner does not have an opportunity to change his response to the information presented after viewing the programmatically correct answer.

Referring now to FGURE 4, the teaching machine shown therein is a modication of the teaching machine shown in FIGURE 3 andconsists of a housing 136|, a siidably removable. photographic lm projector 132, auditory equipment 134 and a motor 136 for powering the blank vwe b talreup reel 13S. A synchronous unit 140 is provided for coordinating the related functions of the various components. A support 142 may be provided for containing some of the components as described in the discussion of FIGURE 3. A loudspeaker 144 is, of course, provided for auditory equipment 134.

Y A reiiecting surface 145 is positioned within the housing so that the photographic image of the information to be presented to the student learner may be relected onto the undersurface of information viewer plate 146 and then through the blank web of; writing material 152. The information viewing plate 146 is positioned on the undersurface of inclined writing surface 148 and is positioned Within or immediately below the opening 150 and is retained thereby through brackets 154.

The web of writing material 152 is contained in unused form on reel 158 and is caused to reel'upon the top powered'reell:

An information'viewer plate 160-is slidably mounted within a sliding track 162 and also has Van answer restricting portion 166 at the lower end thereof. The information restricting plate is provided with a handle operator 170 by which the student learner may slide the information restricting plate in the sliding brackets 162'.

In titte-*positionl shown theinforrnatit'inv may be transmittedl tothe student through the information Lviewer plate 14.6 and he may then record his responses to the interrogatories posed therein. interrogatories and wishes now to view the program.- matically correct'answer which is restricted from his view byanswer restricting platel 166he pushes the handle 17! upwardly and immediately upon motion there-o switch 174 is actuated' which reels the portion of the blank writing web upon which Vthe student has transcribedV h is responses under the information restricting plate and' the housing at 176. The student may then view the pirogrraminatically correct `answer as the presented intelligence remains upon the return o f the information restricting plate, 16.0., to rest position whereby the answer is again covered and the. switch 174. then causesv the program-v matic sequence to be. changedtq the. next frame. The possibility 0f the Student kemer sheeting 0.11 .the teaching When he has completed the machine by uncovering the answer portion by returning the plate 165 almost to rest position and recording his. answer upon the blank writ-ing web is obviated by having the student draw a heavy line on the blank Writing web immediately at the beginning of the sequence of presentation of the learning,k material which. thereby prevents. his skipping a space and then recording his answer after the Writing webv has already reeled under the housing portion 176. Of course, this method of cheat prevention is validI on any. modification of the machines.

T oy provide the student with the availability of a rerun of all or a portion of the sequence, a rerun switch 179. may be provided. -v

It is to be noted that this. modiiication ofthe teaching invention may be battery powered by batteries as weil as outside electrically powered from conventional current lines. The machine is completely automatic in operation. and mail. be provided with an accessopening to change the reels 138 and 158 and the reel supports therein may. be spring. mounted as aforementionedl for ease in mountine. andshansins.

The same' seguencingof thelearning material and correspending auditory. equipment may be carried out in this modification as was described in connection with the teaching machine of FIGURE 3.

Referring'to FIGURE 5p, the structure shown therein is a top plan, View off( the inclined writing surface of FIGURE, 3. The information viewer plate 146 is posi-w tioned conveniently upon the, inclined writ-ing surface 148 in theopening v150 and is Supported therein by bracletsp1'54.

It is to be noted that the correct answer to this frame is covered up at the time which the frame is shown to the student so that the student never has the opportunity to look at the answer and then write his responses thereto.

The reels 158 and 138 may be provided with spring supports 178 so as to provide for ease in changing and removing them.

FIGURE a shows a detailed View of the answer restricting plate 166 and its contact with the switch 174. A spring member175 is provided on the undersurface of 166 so that the switching means of switch 174 is actuated both on the downward and upward motion of answer restricting plate 166.

FIGURE 6 shows a cross section of FIGURE 5 on the section line 6-6 and shows the relative positioning of the information restricting plate 160 and its associated guides 162 in relation to the inclined writing surface 148 and the information viewing plate 146. The blank web of writing material 152 is shown immediately overlying the information viewer plate and being reeled upon the upper reel 138.

Keyboard Variation The keyboard variation of this teaching machine is herein illustrated by reference to the specific example of a typewriter. Such a typewriter is designed to be used with a programmed re-usable information web which is in the form of a strip of paper or like material having the dimensional characteristics compatible with the width of the carriage of the particular typewriter in use. This information web may be used for inscribing information and interrogatories upon or may be used for inscribing a programmed sequence of typing materials by which the student may compare the prepared program with his own typing immediately after recording the same.

The latter use of this variation of the teaching machine is best accomplished by recording upon the information web a series of letters and/ or numerals or other symbols in a typed form. This information web is then covered on the keyboard side of the typewriter roller by a blank web of writing material so that the student does not see the typed material until after he is required to type the same material upon the blank web but immediately after so typing each portion the student has exposed into view the programmatically correct typed material which is recorded on the information web underlying the blank writing web upon which he is typing. In this way the student obtains immediate feedback of errors and correct responses which is critical for learning.

It is contemplated that in the use of this typing machine the student will type from either pre-printed or auditory programs of instruction. This material will have the same terms and symbols as the typewritten or printed letters and/or numerals recorded upon the information web. Effective use of this modification of the teaching machine may be obtained when learning material is presented in an auditory fashion so that the student can see his typing superimposed over the correctly typewritten material immediately upon typing the auditory information. This use of the typewriter variation is particularly important in teaching typists, secretaries and stenographers to type 14 typing is immediately recorded, i.e., incorrect letter, 'numeral, or symbol usage, spacer bar error, punctuation and capitalizing errors.

Referring now to FIGURES 7, 8 and 9 the typewriter variation of the teaching machine shown therein is a standard mechanical or electrical typewriter in all respects other than the carriage of the machine or more specifically the roller and the knobs actuating the roller. Thus the teaching machine may be manufactured as a complete machine or in an addition kit form. In addition tothis change in the standard machine equipment there is an addition of a template which remains stationary relative to the base of the typewriter and is attached thereto and is designed to slide under a transparent surface of the typewriter roller so that light from an interior light source may be propagated from the interior of the roll onto a specified portion of the roller whereby typewritten material on the information web is transmitted through the blank writing web so that the student sees such written material immediately after he has typed the same.

Referring now to FIGURE 7 a fixed U-shaped template 180 is shown. This template is fixed relative to the base 182 of the typewriter 183 and extends outwardly to the right of the typewriter a suiiicient distance so that the typewriter may be indexed at the left hand side of the paper.

The roller 181 which is specially designed to receive the template 180 is best shown in FIGURE 9 wherein the template 180 enters the underside of the rotatable transparent roller sleeve 184 which is mounted on carriage 185. The template is also positioned on the inside surface of the lixed core of the roller 186 by longitudinal brackets 188. Core 186 is provided with a longitudinal slot 187 therein at the level at which the typewriter keys strike.

FIGURE 8 shows the modication of the standard carriage structure which permits core 186 to remain stationary with respect to the carriage and the roller sleeve eiiiciently and quickly from dictaphones or similar devices 184 to be rotatable thereabout. A gear housing 190 is provided between roller knob 192 and the roller 181. The roller core 186 is rigidly attached to the interior of gear housing 190 by conductor rods 194 and the gear housing 190 is then rigidly attached to the carriage 185 so that the core remains stationary to the carriage and reciprocates therewith. The core may be rigidly attached to a gear housing at either one or both of the ends of the roller.

As the core 186 is rigidly attached to a member between the roller and the roller knob a bypassing gearing system must be employed. Such a system is shown by connecting roller knob 192 and associated spindle 195 with pinion gear 196 which in turn is enmeshed with idler gear 198 which is supported by spindle 199. A cylindrical gear 200 is positioned between idler gear 198 and sleeve roller gear 202 so that power may be transmitted to the latter by means of the former. Cylindrical gear 200 is attached relative to the carriage by a suitable bracket such as support bracket 204. Sleeve roller gear 202 is designed to be on annular gear but the only requirement at the left side is that it has a central opening suiicient for conductor rod 194 to pass through while the right side gear must be annular to permit the passage of the template therethrough.

Likewise, the gearing system as well as the supporting structure may be positioned on one or both sides of the roller. Y

To fulfill the function of allowing the material recorded upon the information web to be visually displayed through the blank typewriting web a light source such as a iiuorescent, neon, or elongated incandescence bulb 206 is arranged in the'roller core 186 and is supported therein by means of insulating spiders 208 at either end thereof and has a socket housing 210 rigidly connected to the spiders 208 for conducting electrical current to the bulb 206. The conductor rods 194 provide electrical conductors 17 ication of the typewriter variation shown in FIGURES 7 through 9 and particularly the modication shown in FIGURES 10 through 1l is the modification shown wherein a pivotable template 240 is rotatably mounted upon the conductor rods 194 at either end of the roller so that the template may be swung into and out of covering position of the slot 187 whereby the light source 2do may be continuously lighted and the template withdrawn from covering position at the extreme left hand portion of the carriage movement so that an effect exactly simi lar to that described to the modification of FIGURES 10 through 11 will be observed by the student. In this modiication template arms 242 are provided which are in pivotable connection with the conductor rod through pivot member 244. Connected to an end of these members 244twithin the gear housing 19u is a solenoid lever 245 which is pivotally connected at the outer end thereof to a solenoid rod 248 which is operated by means of solenoid 259. l

As this solenoid 250 is only intended to operate when the carriage is in the extreme left hand position on the typewriter base a similar pair of spring contacts or spring fingers are arranged in a slot 234 between the carriage and the base of the typewriter as was described in El URE 1l. Whene these spring lingers 252 and 254 contact one another the solenoid 256i is caused to operate whereby the described etfect is accomplished.

In order to operate the modification of FIGURES l2 and 13 a series of tracks must be provided on the undersurface of the carriage which are then in contact with electrical brushes which are connected to the base of the typewriter and are then in electrical contact with the electrical source 216. The first of these electrical tracks is track 256 which electrically contacts the light source socket 2113 by conductor member 212 and conductor rod 194 at one end of the roller. Electrical track 258 serves the duel function of carrying electrical current to the electrical socket 2.11? on the other side of the roller and provides one side of the solenoid coil with electrical contact to the battery source 216. Electrical tracks 25o and 25S are connected respectively by electrical brushes 26d and 262 to the battery source 216. The other end of the solenoid coil 23@ is connected to electrical track 264 which is then contacted by electrical brush 266 which is connected to one of the spring fingers 252, in this instance the spring linger is connected to the base of the typewriter. The depending spring linger 2511 which is disposed at the right hand side of the carriage is then connected by connector 268 to an electrical track 270 which is contacted by electrical brush 272 and is in electrical contact with the battery source 216 so that when the two spring lingers contact current is carried from one side of the battery or electrical source through the solenoid 25) then through the other of the electrical tracks and electrical brushes to the other side of the battery or electrical source. In this manner the described actuation of the template 249 is caused to occur.

FIGURES 14 and 15 illustrate a more automatic type of operation and somewhat more complicated structure to perform the type-Writing instruction function of the instant teaching machine. In these Figures the roller 181 and the base 182 of the typewriter 133 are essentially similar to the same components which were described in relation to FIGURES 7 through 9. In the first described typewriter variation the template was rigidly lixed with respect to the typewriter carriage. In the modification shown in FIGURES 14 and 15 the template 28@ is constructed of a tlexible opaque strip material whereby it may be rolled upon a reel 282 bracketed to the base of the typewriter 1&2. The roller end of the exible template 284 is designed to slidably engage therinterior of the roller core 13o so as to cover that portion of the slot 187 to the right of the key striking position and is supported for this purpose by brackets 1%. Connected to the end 234 of the exible template is a helical spring 2do disposed within the interior of the roller core and disposed about the periphery of the longitudinally disposed light source (as best shown in FlGURE l5). This helical spring is connected to and utilizes as a reaction surface the right hand insulator spider 2% so that the spring is in tension and increases in tension as the end 2M is pulled toward the right hand side of the roller 131. As the ilexible template is so'moved across slot 187 an increasingly longer length of that slot is exposed so that the light source which is in continuous operation propagates light through the slot and through the information sheet so as to shadow transfer information upon that sheet onto and through the blank writing web so that the students typed wording may be compared with that on the information sheet to provide the aforementioned comparison learning value.

in order that the flexible template 289 may be rolled upon the reel 282 and conveniently stored a guide ZSS is employed which is connected to the roller core at the rignthand side thereof and serves to transfer the flexible template from the plane represented by the slot 187 into the plane necessary for it to engage the reel 282.

The powering means and `storing means for the flexible template is shown in FXGURES 16 and 17 and consists of the reel 2252 which is supported by a pair of brackets 29) upon the side of the typewriter base 182.

ln order that the flexible template 2% may be reeled onto the reel 282 as the carriage moves to the left on the typewriter a positive drive means is provided so that the template may be wound up against the tension of the helical spring 285. Such a drive means is shown as 292 which consists of a reciprocating rack 294 which is connected within the interior of the typewriter to a suitable reciprocating element by which continuous reciprocal motion is available for actuation of the rack 294. The rack 2% extends through the typewriter base 182 by means of slot 296. Therack 294 engages pinion gear 298 which then transmits power to the sleeve 3% which is rotatably mounted within one of the brackets 299. Connected to the other side of this sleeve is a ratchet gear 302 which has internal ratchet teeth 364. Rotatably connected to a plug 3% which is rigidly alixed to the interior of the sleeve 300 is the spindle 3% which rotatably supports the reel 282 within the plug 3% and hence in rotating engagement with the bracket 290. The other end of the spindle 3dS is also in rotating contact with the other bracket 2% except that a damper coil spring 319 is rigidly connected by one end thereof to the spindle 3418 and is connected to at the other end thereof to spring housing 312 which is in rigid contact with the bracket 290 so that damping effect is provided for the template 280 whereby the helical spring 286 which is a stronger spring than is 31@ will not impact the roller end of the template against the left hand side of the slot 187 when the template is unwound from the reel 282.

ln order to transmit power between the internal ratchet teeth 304 and the reel spindle 308 a ratchet member 314 is provided which is spring biased outwardly and pivotally connected to the spindle 3118. Whereby as the rack 294- is reciprocated the template 2S@ will be reeled upon reel 282 by means of a power transmitted to ratchet 314. ln order that during the non-powering stroke of the rack the reel is not reversed the same amount it has just proceeded in a winding direction by means of the helical spring 286 pulling the template from the reel a catch means 316 is connected to the typewriter oase 2t2 and does not reciprocate with the rack 294. This catch means inacts upon the reel 282 by means of itting in the notches 318 disposed around the periphery thereof.

ln order to permit spring 286 to return the template 280 to the left hand side of the roller core the rack 294 must be cleared from contact with the pinion gear 298 and for this purpose a cam member 320 is provided which is actuated by the initial movement by the carriage to the right. It is to be noted that the cam member 32@ clears both the rack 294 and the catch means 3io from engagement with the pinion gear and the reel respectively.

vThe gearing system 292 above described is only representative of a gearing system which could be employed to reel the template 280 into a compact housing to avoid the possible objection to the rigid U-shaped template shown in FIGURE 7.

The winding of the template upon the reel 282 may be controlled with respect to the spring constants of the two springs 2&6 and 3 1@ whereby the roller end of the template is maintained at all times at the key striking position of the movable carriage 185 so that the described function results.
