Patented Mar. 10,1914.-

' Application filed February 13, 1913. Serial No. 748,219.

To all whom, it may concern:

Be it knownthat I, JUAN Gr. HOLGUIN BURBOA, a citizen of the Republic of Mexico, residing at Hermosillo, in the county of Hermosillo and State of Sonora, Mexico, have invented a new and useful Type-Writing Machine, of which the following is a specification. 1 a

The present invention relates to improvements in typewriting machines, the primary object of the present invention being the provision of a machine so constructed and arranged as to permit of the operation thereof to record eoincidently with speech without the necessity of transcribing, the construction permitting the writing of a single or a plurality of letters simultaneously, there being provided a plurality of cases of type keys, each case of-which is constructed to engage the platen and its individual presentation spaced thereupon so that the one type of one case will not interfere with the type of the other case.

A further object of the present invention is the provision of keys so disposed as to be comfortably manipulated by both hands of the operator, there being preferably three series of keys to each hand and six keys to a series, while to provide extra means for operating the different mechanisms of the typewriting machine, wrist actuated keys are also provided one for each hand.

A still further object of the present invention is the provision of means controlled by one key or any combination of keys,

less than the number of letters of the alpha bet, as for instance, six keys, a full alphabet may be controlled and actuated, the

combination of the respective keys or a s1n-- gle ke of each series operating the distribevice or in. other words, the selector which will cause the proper actuation of the selected ke to type presentation position upon the aten.

A still fhrther object of the present invention is the provision of a plurality of so lectors one to each hand set of keys and one to each wrist set of keys, a fourth selector being provided and controlled through the various combinations of both finger actuated sets of keys to perform various operations asregardsthe spacing of the platen,

- the rotation thereof and the movement during the writing of the type or the return of the carriage to initial pos tion.

inatieally In. general, the present typewriting machine, consists of key and wrist actuated lTlBELIISWhQIQbY the various types of, the different cases are placed in platen engaging posltlon to cause the presentation thereto of a single type or in the present instance, fouritype, so that short words, portions of words, or abbreviations may be written simultaneously, there being provided automatic spacing mechanisms controlled due to the number of type actuated so that the platen will be rotated the necessary number of spaces for resenting, in type presentation position, a c eansheet. The rotary platen is so mounted as to be moved normally vertical from the top to the bottom of the page by the spring actuating mechanism, the same being returned from the top to the bottom of the page for the new page by an autoactuated mechanism and against the tension of a spring. The platen also retates in the same sense when line writing and when beginning a new line, The paper which receives the upper end of the type is disposed within the hollow platen and wound from'one reel to another so that the action of the paper from one page to another is controlled from the key board and automatically stopped at the desired point so that at the instant of the movement of the platen from its uppermost to its lowermost position, a new sheet of paper to constitute a new page will be placed upon the platen in a position for receiving the beginning of the new page. Other means for limiting the marginal position of the platen and for tabulating is provided, the same being controlled from the key board. A back spacing device is also provided in connection with the marginal device so that the platen may be moved rearwardly the desired number of spaces for back spacing.

The control for the present typewriting machine is preferably pneumatic, but it is evident as will presently appear that the pneumatic devices may be dis laced and electro magnets controlled thougi any form of generator or battery may be provided.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made with in the scope'of what is claimed without departing from the spirit of the invention.

In describing thepresent invention, the various mechanisms will be taken up in turn and under the following sub-topicsz' The frame and main motor; type basket and control mechanism; platen and carriage; platen spacing and back spacing mechanism; paper control; ribbon mechanism; marginal stop and tabulator device; type basket actuating mechanism; and 'signal device. 1

Frame and main m0tor.-Refer;ging to the drawings, the numerall designates the frame and easing, said casing being provided with the forward extension at the lower edge thereof provided with the op.- positely inclined faces 3 and 4 which provide a comfortable support for the respective left and right hands of the operator who sits to face the casing with his left hand upon the inclined portion 3 and the right 'hand upon the inclined portion 4. Provided in the front of the casing is the aperture 5, whereby the various type bars, as will presently appear, may be readily had access to for cleaning and also whereby the visible writingupon the platen 13 may be readily seen at a glance.'

The upper forwardend of the casing 1 is cut away seat 7, while the extreme rear portion .is cut away, as at 6, to provide for 5 the necessary movement of the vertically movable platen 18, the detail of which will be set forth later on. Mounted in-the rearof the casing, as clearly shown in Figs. 2

and 3 are the two pneumatic motors 8 and 8, 10'

each one of which is actuated by the re .spective feet of the operator through the flexible connections 9, each of which is disposed overthe two pulleys 10 and 11 and is connected below the casing to a treadle (not 5 shown).

By this means the respective motors 8 and 8 are operated alternately and being of a similar structure to the pneumatic structures used in connection with piano players and other suction machines, will 120 automatically operate to create the necessary vacuum within the vacuum chamber 12 Whichis also supported, and carried withinthe'casin 1 Type 'lheplaten 13is mounted for movement vertically up and down at the rear 0. the machine, and'the detail of such actuating mechanism will be set forth later on, while the type basket which as shown in Fig. 12, is 130 as7cet and controlmechanism.

composed of the respective sections A, B, C and D, the sections B, C and D being station: ary and disposed within the are of a circle so that the respective type bars will be properly presented, while the type bars of the section A constitute a movable section, the construction of which will beset forth later on, and is controlled to present a single type at a time, when desired.

Each type bar of the respective cases, is controlled and constructed as shown in Fig. 8, the type bar 14 being pivotally mounted in the supporting means 15, and having its short arm 16 connected by a link 17, whose other end is connected to the movable section 18 of the bellows 19, the same constituting a vacuum actuated motor for actuating thetype bar 14 to present its type 14 in type presentation position upon the platen 13.

In the machine herein. illustrated, each of the respective, sections A, B, G and D of the type basket are controlled by the various selector devices20, 20, 20 and 20, these devices hereinas described and known as a selector, and all of which are constructed similarly, so that the description of one will suffice for the description for all.

The detail structure of the selector is clearly shown in Figs. 7 8, 9, 8 and 9, and consists primarily of the lower disk 21 which constitutes a vacuum chamber 22, as clearly illustrated in Fig. 8. This chamber 22 has a nipple 23 which has connected thereto the flexible tubing 24 led from the vacuum chamber 12, and as said vacuum chamber 12 is, as before stated, connected to the respective motors 8-8, the vacuum is created therewithin and consequently through the tube 24 in the chamber 22. This chamber 22 is provided with a plurality of ports or ducts 25 and also has rigidly connected thereto, the outer disk 26, which conpresentation of the selected type 14.

stitutes with the disk 21, the supporting medium for the plurality of oscillatory disks a, b, 0, (Z, c and f. The outer disk 26, as clearly shown, is provided with a plurality of ports 26, whose mouths each have connected therein the nipple 27, said nipple 27 having led thereaway from the tube 28, which provides a means whereby the vacuum effect produced, as will presently appear, will actuate its selected motor 19 to cause the The various oscillatory disks or rings as a, are mounted properly for individual movement between thedisks 21 and 26, and each is pro-.

vided with a plurality of apertures 53 and exhaust ports 54;, the apertures 53 being disposed to be placed in registration with the respective apertures 53 of the adjacent oscillatory disks so" as to provide, by the action of the disk, as f, Fig. 8, or by the combined action of two or more of the disks as a,registering"conduits from. one of the ports 25 of the vacuum casing 22 to one of the ports 26 of the plate 26, this action causing the diaphragm 45 carried by the support l3 and having the casing 14,- to be inwardly flexed to actuate the valve stem 46 carrying the valve 17 and against the spring l8, opening the port of the casing 21 and closing the exhaust 01' outlet port 50, all

clearly shown in Figs. 8 and 8. This action will direct the vacuum effect from the chamber 12 through the tube 51 which is connected to nipple 52 of the casing 21 to operate the selected motor 19 and cause the proper presentation of the type 14:. Upon the non-registration of the selected disk (1,

i b, (I, (Z, c or f, or any combination of them so as to cause the intersecting of any of the channels formed by the various ports 25, 53 and 26, the valve stem 46 \Vlll be released due to the suction action upon the diaphragm 45 being released, so that the spring 48 will move the valve 17 to openthe port 50 and close the port of the chamber 21,

this action permitting the spring of the motor 19, due to the opening of the port 50 to the atmosphere, to assume its'expanded position so that the type bar 14 will be moved to its normal position. The type bars may be constructed to be returned by springs or by.gravity and still be within the scope of the present invention.

In order that the respective oscillatory disks such as a may be operated selectively to produce the desired combination and operate the selected type bar 14, or cause the actuation of the desired mechanisms aswill presently appear, each disk is provided with an 'aperturcd arm or lug 29, projecting radially therefrom and connected by a link 30 to the free end of a link 31,. the link 31 being pivotally mounted at its other end to a fixed support 32 disposed conveniently with relation to its respective selector. Led from the connection between the two links 30 and 31 is an operating means 33, which may be a flexible cord or any rod which carries thereupon the disk 35 to coact with the stationary disk 34 to extend the spring 36 so that the oscillatory disk may be returned to its normal position upon the release of the manually controlled selecting key 39-39 or 39. The detail of this struc ture is clearly shown in Figs. 8, 9 and 26, the connection 33 being preferably connected to an arm- 37 of a bail 38 for operating the respective selectors 20 and 20' or to a lever 42 foroscillating the disks of the sc lector 20. The respective levers 4-2 are controlled through the laterally disposed le- .of these levers 4O toieach right and left hand, and there are preferably as illustrated Q at'the left in Fig. 3, six keys39, which con-' stitute the disk control of the oscillatory 5 disks of the respective selectors and 20, which as will presently appear control primarily the actuation'of the various type bars 14 of the different cases of type.

By the arrangement and construction of the various key levers 38, 39 and 40, in combination with the connections 33 'and levers 42, different combinations are effected by the use of one key or any number of keys therewith to cause the, desired oscillation of the respective disks 0:, b, 0, 3, e and f, 'ofthe respective selectors 20 20 so that the "se-j lected type bar will be actuated to present the type at the desired point upon the paper upon the platen 13. ,AS for instance, the actuation of the single or any combination of the keys 39, at the left hand side of the machine will actuate the selected disk or disks of the "selector 20, which in turn through the respective selected motor 19- controlled thereby, will actuate the selected [type'of the sectional and slidable section AL. of the basket, so that its type will be presented upon the platen 13,-at the extremeleft as viewed in the diagram Fig. 12. Each one of the respective type bars of the section A carries preferably three type, an upper and lower case consisting of the small and capital letters and the various marks used, as

a colon, semi-colon and accenting marks.

This section A, as will presently appear, is' moved to present either one of the respective types to the platen, the small letters being positioned to coact in combination with the single type of the vario iis type bars of thesections or cases 13, C and D so that under ordinary conditions one type of. eachv r case may be operated to present four types simultaneously to the presentation point 0 the platen 13. When a'capital letter is used of the case A, only the type of, the cases B- and C can be used while Where a third type is used only the type of D can be used, the reason of this being clearly apparent from the description to follow lat'eron.

. In the same manner as the individual keys of.a set ofikeys 39f39' or 39*, can be combined to writ-e one letter of the first or second case AB, at the same time, by advanc ing some fingers. 'morethan theothers, the sets of keys 39, 39' and 39 can be combined, and a. combination of them, by. means of the levers 4042,: through the selector 20, regis-' tors a letter of the third case 0, simultaneously with those of-cases AB.

' The selector 20 consists only of two disks a-b and is used as a spacing selector, or for causing the writing of usuallyv the most frequent letters of the alphabet, as for in stance, e and .9. These respective disks a and b ,are controlled through the flexible per cross-bar 59, each of the rods 58 being connections 33-33 operated by the respective disk actuatedkey levers 55-55 disposed at the forward corners of the inclined portions 3 and 4 of the casing and directly below each of the respective left and right wrist-s of the operator. 7

Platen and carriage.The platen 13 is disposed for vertical movement instead of the usual horizontal movement for producing writing, upon the top to the bottom of the page, while. the same is rotated horizontally during the writing of a line, the-same being actuated a space ora number of spaces I at a time according to the number of type that are presented to the platen through the actuation of the keys and .combinations thereof. A lower cross-bar 67 is connected by means of. the two vertical rods 58 to the up movable and journaled for vertical sliding movement within the stationary or fixed tubes 6O mounted properly within the casing, the axis 61 oftheplaten 13 being j0ur naled in the cross-bars 57and 59 for-rotation while the bars or rods 58are mounted within. the tubesGO for vertical movement, the said' rods'58 and cross-bars'57 and 59. constituting the carriage for the platen and bodily movable vertically.

' 9 In order to" produce the necessary hori- 5 zontal rotation of the platen 13 to. present a new space. for the presentation of a type thereto, after the actuation of the type bar controlling keys of the machine, the motors 62'and 63, which are of the suction bellows type, areprovide'd, and have'their control through the vacuum chamber 12, and the se- 1 lector 20, one of the levers 42 being the ontrol therefor, "so that these motors 62-63 will be operated to operate the crank shaft .64 which is journaled in the respective bearf ings 65, and 66. As clearly shown in Fig.2,-

there is keyed upon the crank shaft 64, a, gear 67, which under normal conditions is in mesh with the gear 68 carried upon the lower end of the oscillatory and rotatable shaft 69, this shaft 69 being. journaled within the swiveled or swinging-block .70 disposed between the spaced arms 71' of the 1 supportinglugs 72. The supporting lugs 7 are secured to one of the tubular supports 60 which constitutes one of the carriage guides.-

Theshaft 69 being thus rotated, rotates the upper gear 73, wl'nch is at that time in mesh with the gear 74 upon the lower end of the vertical shaft 7 5', this vertical shaft 75 ha'v-' ing keyed upon it the intermediate gear 76 for actuating the escapelnent 82, as will presently appear, and the upper gear 77, which constitutes the main operating gear foiig the rotation of the platen 13, the dial 202', and the marginal control 206, all 31s clearly shown in Fig. .11. I

A gear 78 is in mesh at all times with'the 13( Loeaeeo gear 77 and transmits motion through the large gear 79 to the long gear 80 which 1s disposed vertically of the machine and in mesh at all times with the gear 81 connected to the platen 13 and its shaft (31 so that regardless of the position of the platen relatively to the casing in its vertical up and down movement, the gear 81 will cause the desired rotation of the platen to present a new space for the presentation thereto of the type. By reason of the fact that the lever .12 with the selector 20 for actuating the motors G2 and 63 are operated at all times through one of the levers 40 controlled by any one of the keys 39, 39 or 39, the platen 13 will be rotated one space for each type, but should four type be presented as illustrated in Fig. 12, the motors G2 and ($3 will be rotated to impart to the platen 13 a movement equal to five spaces which constitute the four spaces for each type and the extra space between the type for the next space to be printed.

In order to provide a means for indicating at a glance the position of the platen relatively to the type line being printed, a gear 200 is in mesh at all times wlth the gear 201 which actuates the dial 202 disposed at the fO1\'t11(l upper edge of the machine and in ready view of the operator.

The control device for the respective motors 62 and 63 is clearly shown in Figs. 18, 14, 15, 1G, 17 and 18, and includes the two stationary plates 301 and 302 which have mounted for oscillation therebetween, the controlling rotatory disk 303, the tubes being led from the vacuum chamber 12 to the ports of the disk 301 and to the motors 62 and 63 through the respective tubes 62 and 62 and 63 and 63 to the disk 80.2, the rotatory disk 303 being provided with the recessed portion, as clearly shown in Fig. 17, so as to cause the inter-linking or intercommunication between the respective tubes 02 or (32", or 63' or 63 to impart the necessary action to the movable bellows of the motors 62 and 63, respectively, and consequently cause the desired act-nation of the shaft 64:.

In order to operate the platen carriage to impart. to it the necessary upward vertical movement, due to the line spacing and also to impart to it the descending vertical movement during the change from a written page to a new page, the shaft 69 must be swung so as to disengage the gear 73 from the a gear Hand the gear 68 from the gear (37, this being effected through the motor 83, controlled through the selector 20, said n10- tor 88 being oymrziblyconnected to the bell crank lever 8-1 which is connected to the sliding block85 mounted upon the twopositioning of the gear, 87 into mesh with the gear 88, so that the shaft 69 is rotated to actuate the gmr 89, and as the bevel gear 89 is placed in mesh with the bevel gear 90, the shaft 91 journaled in the bearings 92 and carrying thegcar or pinion 93 is retated. This rotation controls the motion to the toothed rack 941 of the platen carriage, said rack being disposed between the crossbars 57 and 59, and causes the platen carriage to be elevated the desired spaces, as for instance, one line, two lines or three lines, or will cause movement downwardly of the platen 13 from its highest to its lowest point upon the presentation of a new page and against the tension of the carriage actijlatingspring 50 (Fig. 11) which is of usual construction and is connected to normally elevate the carriage.

The escapement mechanism for permitting the movement of the carriage and platen due to the shifting from one line to the next and for varying spaces as for instance one, two and three spaces, consists of the toothed rack 93 carried at the opposite side of the platen to the rack 94, the same having in mesh therewith at all times the gear 96 carried upon the swinging shaft 96, the block 97 being constructed and arranged according to the sliding block for swinging the shaft and placing the gear 96 into and out of engagement with the rack according to the actuation of the motor 99 and consequently the desired spacing required. The block 100 is the swingingly journaled block for the shaft 96, while the escapement 101, shown at the right in Fig. 2 and which is constructed similarly to the cscapement 82, is provided for actuating the. shaft 96 or rather controlling the actuation thereof to permit the movement of the platen and carriage the desired and selected spacing distance from one line to the next.

In order to permit the upward and downfixed to the frame of the machine so as to provide a rigid support therefor.

Platen spacing and back spacing mechanism.-In order that the platen, as before described, may be rotated a single space or up to five spaces in the present instance, an

These two stops are adjustably ,mounted upon the guide rod 106 which is escapement device, as clearly illustrated in Figs. 19, 20 and 21 is provided, this escape- -ment device also being similar to the devicc= 101 for controlling the vertical movement of the platen carriage, both of such devices being constructed for control from the key board and through the vacuum chamber 12.

The gear 7 6 in this instance as before stated, is geared to the rotatable casing 82 of the escapement device 82 and this casing is provided with the teeth 107 and the facial pins lug 113 being connected to one end of the carriage and having fast thereto, a pin 114,

which forms a journal for the points 115 of the respective tooth engaging fingers 116,

117 and 118, there being a single finger 116 formed integral with the lug 113, a plurality of four intermediate fingers117, and a single flexible finger 118. This finger 118 is provided with the flexing end 119, which is normally, held coextensive with the main body of the finger 118 by means of the spring 120. Each of the respective fingers 118 and 117 are provided with a pin 121, which overlaps the adjacent finger, as clearly shown in Fig. 20, so that the fixed finger 116 limits the movement of the respective fingers in the direction of'the arrow Fig. 19 and consequently in a position'for engaging the teeth 107 to lock the disk 82 against, rotation. The springs119 are connected to the lugs 118 of the Various movable fingers 117 and 118 to form a resilient means for permitting the back stepping or back spacing of the disk 82 and consequently the platen 13 by means-of the back spacing motor 129 which is provided with. the flexing arm 130 connected by the pivoting lug 131 to the niovable section 132 of the motor. This operation is controlled from the keyboard to back space the disk82 one space as desired.

In order to-control' the actuation of the carriage 112, the same being maintained in its normal position by means of the spring 125, with the finger 119 in engagement with .one of the teeth 107 to maintain the disk 82 in the desired position, and so as to bring one of the respective teeth 117 orthe flexing tooth 118 in engagement with one of the teeth 107 to permit of the movement of the disk 82 and consequently the platen 13 the desired number'of spaces, the flexible connection or cord 122 is trained over the rollers 123 and 124 and has one end connected to the carriage 112 to move the same against thetension of the spring 125, this structure bemg clearly illustrated in Figs.- 20 and 21. This flexible connection 122 is connected to'the pivoted bail or lever 126,

carried upon the shaft 127 within the casing,

this bail or lever 126 being operably connected to the controlling members of the respective motors 128-, there bemg five of these motors each of a diflerent' magnitude of movement, so as to control the relative move ments of the lever 126 and consequently the difierence of pull upon the cord 122 so as to present the selected one of the respective fingers 118, 117 or 116, to its respective tooth 107 ofthe dial 82 and thus consequently permit the necessary movement to the platen 13. By this means, it will-be seen that the actuation of the selector 20*, due to the move ment of any one of the levers 42 will control the actuation of any one of the motors 128, or any number thereof, so as to properly actuate the lever 126 and the respective fingers 1 18, 117 and 116, so that the escapement drum 82 will bepermitted to move the desired distance through its motor controls 62 and 63 heretofore described.

Paper c0ntr0Z.-In a machine constructed for this character of work, it is desirable that the necessity of removing a finished page from the platen and the placing of a new page thereupon be dispensed with, and in order that an automatic means may be pro vided for placing upon the surface of the platen, at any desired time, a new sheet of paper, and also provide a means for retaining the succeeding new sheet and also the sheet theretofor'e printed upon, the detail structure as shown in Figs, 22 and 23, is designed and employed. In this structure, the .platen 13 is hollow and is provided with the longitudinal slot 133 throughone side there of while journaled within the platen and substantially the full writing surface thereof, is the supply roll 134, and the winding roll 136, the paper 135 being led from 'the supply roll 134 through the slot 133 around the exterior surface of the platen 13 and through the slot 133 to the winding roll 136. To cause the movement of the paper written upon and the placing of a new sheet upon the exterior of the platen, a motor device, as

clearly shown in Fig. 23, is provided. In I doing this, the nipple 137 is connected by a j flexible tube to the vacuum chamber 12, and

its duct is in communication with the duct 6 138 formed in the rod 58 and bridging member- 59 of'the carriage, the other terminal of the channel or duct 138 being in communication with the duct or channel 139 formed in the upper end of the axle 61 of the platen 13. This structure isclearly shown in Fig. 22. Led from the nipple 140, formed upon the axle 61 is a tube 140', which is in comtions 143 and 144 of said arm 142 to the opcrating link 141-5. This link 1 15 is connected to the pawl carrying arm 14:6, which is disposed to engage the ratchet teeth 1 17 normally held. against retrograde movement by the arresting pawl 1418, to thus 'rotate the large gear 149, which is 'in mesh with the small gear 150 of the roll 13G.

The movement of the arm 1 12 and its pin and slot connection is such as to impart the necessary rotation to the gear 149, for any number thereof that may be necessary to cause the paper to be moved the proper distance to wind the type writ-ten page within the platen and upon the roll 136 to present a new page upon the surface of the platen' 13. In order to provide a locking means for the paper while 111 type presentation posit-ion, a flexible cord 151 is connected to the movable member of themotor 1 11, passing over the guide pulley 152 and through the spring limiting lug 153 to the brake shoe 154., the spring 155 being so disposed as to normally exert an outward pressure upon the brake shoe 15-1 to wedge the same within the space 133 of the platen and against the sheet of paper at such point. It will thus be seen that the initial movement of the motor 14. 1 will not affect the rotation of the gear 140 and consequently the roll 136 until after the cord 151 has been actuated to remove the brake shoe 154 from engagement with the paper at the slot 133, thus allowing ample time for the paper to be released so that the roll 136 may be operated to remove the type written sheet from the surface of the platen and present thereupon a new sheet.

In. order to provide a pneumatic means for stopping the actuation of the motor 111 when the type written page has been removed within the platen v18, the paper is perforated at intervals, such intervals being preferably the distance fromthe slots 156 formed in one wall of the slot 133 to the adjacent wall of the slot 133, such perforations being thus presented at the proper time to the slot 156 of the channel 157. The slot 156 is extended the full length, or any predetermined distance throughout the length of the slot 133, the same having its nipple 157 engageable with the release side of the valve and control casing J of the motor 141.. so as to act in a similar manner to the release of'the valve 47 of the devices shown in Fig. 8, so that the motor 141 will beopen to' the air and will thus collapse and be stopped in its action as regards the rotat'ion ofthe roll 136, the arm 142-being moved in the opposite directionso that the pawl arm 146 will-ride upon the teeth 147 without affecting the. movement thereof but to be placed in a position for the next succeeding action or page changin In order that envelops may be held upon the present platen, the envelop clips E are provided and are connected to the adjacent scale marked flanges F of the platen 13, as clearly shown in Fig.

Ribbon meclrwnwz'smr lhe ribbon mechanism and the control therefor is clearly shown in diagram in Fig. 27. the mechanisn'i. for operating the shaft; 168 being shown in Figs. 2 and 11, and. consisting of the motor 158, which is controlled at the actuation of any one or any combination of the keys to properly feed the ribbon 1713 to present a new portion thereof to each type prcsentation, said motor 158 having its movable member connected through the link 15$) to the bell crank lever 160, whose hooked terminal 1131 is operably connected to the carrying block 102 which is constructed similar to the block 85, and provides a means for tilting the shaft 163. which is rotatably mounted within the swingin block 164, as clearly shown in Fig. 2. keyed upon the shaft 163 is a gear 11kt, which operates the gear 165. This gear 165 has a pulley portion over which is trained the endless chain or cord 166, which is operably connected to the sprocket wheel or pulley 1(17 keyed upon the rotatable and slidably mounted shaft- 168, which constitutes the shifting shaft and power transmission shaft of the ribbon mechanism. Keyed upon this shaft 168 are the two bevel pinions 170--171 and the manually controlling crank 169, which as clearly shown in Fig. 1 is disposed at the upper portion of'the -asing 1 in ready access to the operator.

A bevel gear 172 is disposed at the lower portion of the casing and is carried by the shaft 173 which has keyed upon its inner end the ribbon spool 171, the same being provided with thearcuate slot 175 open to the periphery thereof for the seating therewithin of the ribbon carried shifting actuating pin 180, there being two pins one adjacent to each end of the ribbon 17(3 and disposed to assume the \fll'lUllr; positions as shown in Fig. 27. The shaft 178 is pro vided with a bevel pinion 177 disposed to be placed in mcshwith the pinion 170 of the shaft 168, the respective pinions 172 and 177 being disposed to be operated alternately to cause the desired shifting of the ribbon as is usual'in type writing machines. The upper reel 179 is carried by the shaft 178 and is constructed similarly to the reel 174.

In order to provide a means for shifting the shaft 168 so that the ribbon is continuously fed andrevcrscd according to the erable relation to the spool 192 mounted upon and carried by-the shaft 168.

Each of the respective valves 185 and 186 is provided with a port 187, which is dis posed at the proper time due tothe engagement of the pin 181 with one of the levers 183*184, to move the valve to assume the position as shown at the top of Fig. 27, and in registration with the two oppositely disposed ports 188 and 188, which are connected to the vacuum chamber 12 and to the motor chambers 189; and 190, in the present instance the motor 189 being actuated to properly elevate the shaft 168 to disengage the gears 171 -172 and engage the gears 170 and 177 tocause the ribbon to be fed from the reel 174 upon the reel 179, the parts being in the position they as same at the initial registration of the port 187 of the valve 186.

The ribbon as clearly shown in Figs. 1, 8, 4 and 10 is guided through the stationary guides 192 carried by the frame of the ma chine or the stationary portion of the type basket support, the same presenting the ribbon to all of the four type as illustrated in Fig. 12 sothat four type may be printed sitabulator device 204, and also the ribbon end of a line,

stopped "feed mechanism through the sprocket or pulley 167.

Marginal stop and tabular/0r deoic'e.- In order that the platen 13 may be stopped at any position throughout-the line, as for plain writing, as regulating the margin, or as in tabnlating for bills and the like, a gear 208 forms an inter-linking or connectbet'ween the gear 201, the dial 202 and the gear 204' keyed upon and rotating the shaft 205, this shaft 205 having keyed upon its upper end, the marginal disk 206, clearly shown in detail in Fig. 24. This disk is provided with the main marginal or fixed stop 207, and the two adjustable marginal stops 208 and 209, the same being adjustably connected. for attachment to the periphery of the disk 206, so that, as the plates may be through the respective train of gears at anydesired point. p

The means for ordinarily stopping and releasing the platen 13 at the beginning and comprising either one of the adjustable stops 208-209 and the fixed stop 207, in combinatiomwith the pivoted motor control and-signaling lever 214, which'is disposed to project between the open spaced ends of the open ring 210 which is permitted a slight sliding movement and constitutes the tabulator stop carrymg device. The sigrosaeee naling lever 214 is pivoted at 215 and has its terminal carrying the valve 217 disposed within the valve casing 216, the same being operably the vacuum chamber 12 so that when the stop208 engagesthe outer end of the valve connected with the motor 274, and I actuating lever'214, the valve will move to open the port and permit of the actuation of. the wrist tapping lever 273 (Fig. 3) to signal the operator thatthe marginal stop 220, must be operated to release the platen. The stop 220 is mounted inthe-two lugs 219 carried by the open'ring 210,as clearly shown in detail in Figs. 24 and 25. This stop 220 is provided with the long end 221 and with the short end 222 so that the short end willengage the ,stop208 during the ro-' tation of the disk 206 in the directiomof the arrow Fig. 24, after the engagement of the same stop 208 with the signal actuating member 214, and the manipulationot a key to cause the actuation of the motor 228 through the link 223 which causes the marginal stop 220 to disengage the 'arm 222 from the'marginal stop 207 to place the long end 221 in the path to engage the stop 209 and thusllock the platen 13 atthe beginning of a new line and simultaneously with the spacing of the carriage to present a new line in type presentation position.

' In order to provide a cushioning means for the oscillatory ring 210 when the stops 208 and 209 are in enga ement with the pivoted stop 220, the end 211 which is formed in the shapeof a plunger and enters the air cushion 212, a slight vent aperture 213 being provided to permit the escape of the air and thus provide a pneumatic butter for th platen when the stops 208 and 209 have been placed in engagement with the 221 of the pivoted stop 220.

In order to providea means for present- I platen 13 for tabulat-ing purposes, a plurality of pivoted stops 225 are disposed, as shown in Fig. 24, upon the ring 210 and have their stop engaging ends 226 disposed to engage the stop 207, of the respective stops 225 being provided and being operably through the link 227 as clearly shown in Fig. 10. These motors 228 are controlled throughany of the desired selectors 20, 20, 20 or 20 and the necessary key of the machine. V I

, Type basket actuating .me0ham'sm.-As clearly shown in Figs. 10'and 12, the sectionA ofthe type basket is mounted for ing the thamotor 228 in each connected thereto sliding movement with relation to the other 28, and thus being shiftable to present a single type, at a time in type presentation position relatively to the platen. This case of type bare is therefore carried by the sliding plate or frame 229, whose-upper and lower edges respectively are supported be tween the anti-frictional rollers 230, there being four in this instance, while connected to and carried by the plate or frame 229 and projecting from one side thereof are the two pins 231 and 232.

Under ordinary conditions, the spring S holds the plate or frame 229 and consequently the case of type bars A in the separated position, so that the small letter will be presented when the keys for actuating these type are operated, but should it be desired to present a capital letter, which is the intermediate type upon the respective type bar, a key is actuated and through the se' lector operates the motor 235, whose movable terminal 233 engages the pin 231 and moves the frame 229 and the type toward the center of the machine so that the capital letter will be propelled against the platen.

Should it be desired to place the third character or the one to the extreme left, as shown in Fig. 28, to the platen, the motor is controlled in a similar manner through the selector 20 so as to actuate the movable terminal 234, which engages the pin 232, and as the motor 236 is of a greater magnitude and has a greater movement than the motor 235, the frame 229 and the section A carried thereby may be moved a greater distance or one space farther toward the center of the machine. Upon the release of the type, the spring S will return the frame 229 to its initial position as shown in Fig. 10.

Signal deoi0e.1n a machine of this character, it is desirable that no audible signal be provided, therefore in order to notify the operator when the platen is at the end of a line or at the end of a page, some means must be provided to attract his attention so that the proper key may be manipulated for presenting a new line for returning the carriage. This is accomplished by means of the pivoted tapper 273, which is mounted at the forward right hand corner of the casing 1, and insuch a position as to tap the right wrist ot' the operator whose hands being in the proper position for manipulating the keys 39-39 and 39 with his wrist in proper position for engaging the key 55 will be properly notified that it is time to manipulate thekeys for shifting the platen or the carriage as may be necessary. This pivoted tapper 273 is controlled through the motor 274, which is controlled by the pivoted valve actuating means 214 when either one of the stops 209 is placed in engagement therewith, the nipple connections of the valve casing 216 being operably connected to the vacuum chamber 12 and themotor 274, so that the motor 274: is automatically actuated due to the envgagement of the stop 209 with the valve and a portion of a fourth as herein set forth,

and that various other key operated dcvices may be employed to control the various motors for actuating the type bars, ro-

tating the platen, moving the carriage to and against the spring control therefor, and for actuating the ribbon feed.
