SIGNALING TRANSMITTING METHOD AND APPARATUS Filed May 10, 1930 7 Sheets-Sheet '7 INVENTOR [av/ls M Puffs Patented June 29, 1937 UNITED STATES PATENT OFFICE SIGNALING TRANSMITTING METHOD AND APPARATUS Louis M. Potts, Chicago, 111., assignor to Teletype Corporation, Chicago, 111., a corporation of Delaware My present invention relates to signal transmitting methods and apparatus. More particularly, my invention relates to transmitting methods and apparatus in which a plurality of code signals may be set up prior to transmission, and then transmitted either to a transmitter control tape or a transmitting apparatus.

In ordinary automatic telegraph systems for the transmission of intelligence the messages are built up of code combinations of signaling conditions, and each code combination controls the complete selection of a character or performance of a definite operation at the receiving station. In such systems, therefore, transmitters, or tape perforators for the control of automatic transmitters have generally been arranged to, set up the individual code combinations or character signals of a message in succession, so that an error in transmission or omission of a code signal resulted only in a single error.

In special signaling systems, as for example, commodity quotation distribution systems, recently developed, each message or quotation unit comprises a definite and predetermined number of code combinations transmitted successively in a fixed sequence and the messages or quotation units are usually all of the same length. Thus, in one modern form of stock quotation system, the firstthree code combinations in the transmitted message represent letters of the alphabet which constitute a code designation of the stock to be quoted and operate the receiver to select the recorder allotted to the selected stock. These three code combinations are invariably followed by four further code combinations which set the recorder to indicate the quotation of the stock selected by the three preceding code combinations. A. further code combination, to be transmitted either simultaneously with the four last code combinations or immediately thereafter sets the recorder to indicate the nature of the quotation as high, low, last, orthe like.

In such special systems, provisions must be made not only'to insure synchronism during the transmission of each code combination of conditions, but also that proper message synchronism or phase relation is maintained between the transmitter and receiver with respect to successive code combinations, so that the receiver will be conditioned to receive the stock code combinations while the transmitter is transmitting same in succession, and will be in condition to receivethe number code combinations while same are being transmitted.

Although the transmitters and perforators heretofore used for setting up the code combina tions separately and in succession satisfied conditions met within the standard telegraph systems, such mechanisms are not best suited for stock quotation systems due to the fact that if one code combination of the message is omitted loss of message synchronism would occur. For example, if in setting up a quotation, the operator should overlook the setting up of the fraction code combination of one quotation, the next code combination transmitted, which would be the first letter of the next stock quotation, would be transmitted in a way that would cause a selection of a fraction quotation of the previously selected stock recorder. The transmitter and recorder would then be out of message phase and quotations would no longer be correctly quoted on the recorders in the system.

To obviate such a possibility of error in operation of automatic transmission for commodity quotation systems I have provided novel transmitting methods and apparatus to set up complete quotation message units before transmission of the message unit is initiated, each message unit being transmitted in succession instead of transmitting individual code combinations in succession as has heretofore been the practice. In this way errors are localized in the individual quotations and are not reflected throughout the succeeding quotations.

Accordingly, an object of my invention is to provide novel methods and apparatus for setting up complete message units prior to the initiation of transmission thereof.

Another object of my invention is to provide novel transmitting apparatus especially adapted to a system of telegraphic transmission in which a plurality of successive messages of equal length are to be transmitted which insures the correct length of every individual message by transmitting complete message units at a time, to insure proper message synchronism of the transmitting and receiving apparatus.

It is important that the equipment in stock quotation systems, particularly the transmitting equipment remain of simple design so that it can be operated at a high speed to meet the traffic requirements of stock quotation systems, and a further object of my invention is therefore, to provide simple, compact and efficient apparatus especially adapted for quotation transmission.

Another object of my invention is to provide a novel perforating mechanism electrically controlled from a remotely disposed control means.

A further object of my invention is to provide novel tape perforating mechanisms in which one group or series of perforations is being perforated in the tape while a succeeding group is being manually set up.

Other objects of the invention will appear in the following detailed description of preferred embodiments thereof and are defined by the scope of the appended claims.

In the accompanying drawings there is shown a perforating unit and a keyboard unit embodying my invention. The perforating unit comprises a main frame upon which. is operably mounted means for perforating a large number of holes simultaneously and also punch selecting means which is under control of the keyboard.

Mounted on the main frame I, Figures 3 and 4, and fixed to the top plate 2 thereof are a pair of upright standards 3 and 4 which are bridged by a horizontally disposed punch guide plate 5. Mounted for vertical movement in the guide plate 5 are a plurality of code hole punches 6 which are provided at their lower ends, immediately adjacent to the guide plate 5, with enlarged stop portions 6a, adapted to engage the lower side of aoeaieo guide plate 5 for limiting the upward movement of the punches. The arrangement of the punches is best illus trated in Figures 1, 6 and 7. In addition to the code hole punches 5, there are a plurality of feed hole punches i, one of which is shown in Figure 7. The feed hole punches l are not mounted for vertical movement in the guide plate 5, but are fixed to the guide plate as shown in Figure 7.

In accordance with my invention the punches to be operated are first positioned foroperation and a female die plate or matrix is then moved with respect to the punches for performing the punching operation. The female die plate is referred to hereinafter as the punch plate and the mechanism which carries the female die plate is referred to hereinafter as the punch plate assembly.

The punch plate is designated in the drawings by the reference numeral 8. As clearly indicated in Figure l, punch plate 8 is provided with a plurality of holes arranged in rows, there being seven rows of seven holes each. Holes 6 are the matrix holes for the code hole punches 6 and holes 1 are the matrix holes for the feed hole punches 1.

In the modified form of punch arrangement shown in Figures 8 and 9 only one punch 9 and its corresponding hole 9' are provided in the left hand row of the rows of punches and holes. Also it will be noted that the punch 9 is fixed to the guide plate 5. The purpose of this arrangement is to provide an index record for each perforation operation. In Figure 8 it will be noted that no hole is provided at the point it). The-reason for this omission is that in this modified form this perforation is never used in the code combination relating to fractions.

This is shown clearly in Figure 14 illustrating a specimen of tape I I, where it will be noted that the perforations 12 in the top'row occur regularly every seventh code combination in the series of combinations, thereby-providing a record on the tap of seven units of information by operating less than seven keys. In this view the large circles represent code perforations and the small circles represent feed perforations.

The punch plate assembly is designated as a whole by the reference numeral i5 (Figures 3 and 4) and is positioned for vertical reciprocal movement on guide columns l6 which are fixed to the top plate 2. The assembly l5 comprises, for the main part, a top plate I! to which the punch plate 8 is fixed and a bottom plate Hi. The plates l1 and I8 are held in spaced relation, in a well known manner, by guide sleeves l9 which are received by the guide columns IS. The top plate I! is provided with suitable means for guiding the code hole punches and the feed hole punches.

Bottom plate 3 of the punch-plate-assembly I5, is provided with two oppositely disposed trunnions 24, 24 (Figures 1 and 4) to which are attached the ends, 25, 25 of a pair of levers 26, 26 respectively. Levers 26, 26 are fulcrumed on a. shaft 21 which is journaled in brackets 28, 28 fixed to top plate 2. The opposite ends of the levers 26, 26 are provided with follower rollers 29, 29 which engage the top surface of an operating cam 30. Operating cam 30 is provided with a pair of raised cam portions 3| (see Fig. 4) and 32, which, upon rotation of said cam 30 in .a manner hereinafter described, engage the follower rollers 29, 29 at predetermined intervals,

imparting a reciprocal motion through operating levers 26, 26 to the punch plate assembly l5. For returning the punch plate assembly l to normal, springs 33, 33 are provided. One end of each spring is attached to spring top anchor bars 34, 34 removably attached to the free ends of guide columns I6 and the other ends of the springs are secured to spring bottom anchor bars 85, 35.

The operating cam 38 is secured to a sleeve 40 through which extends the main driving shaft 4|. The main driving shaft 4| is substantially vertical and is Journaled through sleeve 40 to an anti-friction bearing 42 in the top plate 2 of the main frame. The bottom end of the main shaft 4| rests upon a steel ball bearing 43 held in a flanged sleeve 44 fixed to the bottom plate 45 of the main frame I. The ball 43 thus sustains the entire weight of the main shaft 4| and its associated parts and constitutes an end thrust bearing for the shaft 4|. The main shaft 4| is driven by a motor (not shown) through a gear 41 fixed to the main shaft 4| and a pinion gear 48 pinned or keyed to the motor shaft 49.

The sleeve 40 is driven by the main shaft 4| through a friction clutch mechanism 50. The friction clutch mechanism 50 comprises a driving member in the form of a flanged sleeve member 5| secured to the shaft 4| and a driven member in the form of a disk 52 loosely mounted on the sleeve 40. The driven. disk 52 is driven through pins 53 which are secured to the driving member 5| and which extend into notches 54 in the disk 52. In addition, a pair of plates 55 and 56 are loosely mounted on the sleeve member 40. A friction disk 57, such as a felt Washer, is placed between plate 55 and driven disk 52 and another friction disk 58 is placed between the driven disk 52 and plate 56. The plates 55 and 5B, the driven disk 52 and the friction disks therebetween are retained in position on the sleeve 48 by means of a lock nut 59 having threaded engagement with the sleeve 48.

The sleeve 48 has pinned to it intermediate its length a start-stop cam 58. Adjacent to cam 60 is a clutch spring 6| which normally bears against cam 60 and continually exerts pressure against the friction elements. It will be evident that, as long as the start-stop cam 80 is not restrained against motion, power will be transmitted from the main shaft 4|, through the friction clutch elements, to the sleeve 48 and cam 30. When, however, the start-stop cam is restrained against motion, the sleeve 40 and operating cam 39 will remain stationary and the friction clutch will slip. The means for controlling the start-stop cam will be described fully hereinafter.

Tape feeding It is obvious that the tape must be advanced after the completion of each perforating operation to a position to clear the punches preparatory to performing the succeeding perforating operation. Accordingly I have provided a means for performing this function.

Journaled in brackets, not shown, but attached in an appropriate manner to top plate ll of the punch-plate assembly I 5 is the tape feed roll shaft 65 (Figures 3, 4, 5 and 6). Mounted on this shaft is a feed roll 66 in the form of a cylinder ha ing feed pins 61 extending radially around the periphery thereof. Figures 5 and 6 show most clearly the relation of the feed roll 56 to the punch mechanism. There are in the present embodiment of my invention, fourteen feed pins 8'! equally spaced around the circumference of the feed roll 88 and in alignment with the feed hole punches l. The feed pins 61 are spaced apart a distance between the centers of the feed hole punches 1. The feed pins 81 cooperate with the feed holes in the tape H for advancing the tape in accordance with the extent of rotation of the feed roll 68. The punch plate 8 is provided with a groove 68 to clear the feed pins 61 on the feed roll 65.

On the end of the shaft 65 opposite the feed roll 66 is keyed or pinned in a suitable manner a helical gear 10. Gear 18 intermeshes with a similar gear 1| keyed or pinned in an appropriate manner to one end of an auxiliary shaft 12 suitably Journaled in bearings provided at the ends 13 and 14 of a substantially U-shaped bracket 15 secured to a supporting bar 18 fixed to the punch plate assembly I5.

Auxiliary shaft 12 (Figure 4) is positioned with respect to the U-shaped bracket 15 by means of a collar 11 pinned or otherwise suitably fixed to said shaft 12. To the opposite end of auxiliary shaft 12 is fixed a gear 18. It will now be apparent that shaft 12 is restrained from independent vertical movement with respect to the bracket 15, by the fixed collar 1! and fixed gear 18 acting on opposite sides of the bracket '15. It is also obvious that auxiliary shaft 12 and its associated parts are bodily movable with the punch-plate assembly l5.

Gear 18 on shaft 12 meshes with a gear I8 fixed to the end of the main shaft 4|. While gear 19 possesses only a rotary motion, gear 18, with which gear 19 is enmeshed, is adapted to have imparted to it simultaneously a rotary motion through gear 19 and a vertical motion through punch-plate-assembly 5. In order to maintain the intermeshing engagement between gears 18 and 19 at all times, gear 19 is made considerably wider than gear 18.

The feed roll 66 is arranged to be driven from the shaft 65 through a friction clutch 80. The clutch 88 is an integral removable unit and comprises a flanged sleeve member 8| as one operating element and a drive disk 82 as the other operating element. The drive disk 82 is rotatably mounted upon the sleeve member 8|. In addition, a plate 83 is loosely mounted on the sleeve member 8|. A friction member 84, such as a felt washer, is placed between the plate 83 and drive disk 82 and a similar friction member 85 is placed between the disk 82 and the flange of the sleeve member 8|. The friction members are confined upon the sleeve member 8| by an adjustable threaded member 86 and a lock nut 81. The friction members are pressed into engagement with the members BI, 82 and 83 by an annular member 88 comprising a spring with a plurality of radial wings turned alternately right and left. The wings engage corrugations in the threaded member 86 and the loose friction plate 83 and cause the friction plate 83 to turn at all times with the principal operating member 8| while at the same time pressing the friction elements together. The tension of the clutch is adjustable by means of the threaded member 86 and its lock nut 81.

The connection for driving the feed roll 86 from the disk 82 comprises an arm 88 fixed to the feed roll 68 and extending into a slot 80 .in the disk 82, as shown in Figures 3 and '4.

the operation, the disk 82 is restrained against rotation and the feed roll 88 is therefore held stationary. Forthis purpose, the drive disk 82 has formed on its periphery two diametrically disposed radial stop portions 9I and 92 (Figure 3) either of which is adapted to be engaged by one end 93 of a lever 94 at a certain interval in lower end 91 of the lever 94 has co-operative relationship with one end 98 of a trip lever 99 (Figure 5) which is pivoted intermediate its end on a pin IN. -The other end I92 of the trip lever 99 is disposed in thpath of movement of a pair of studs I93 and I94 which extend radially from the periphery of the operating cam 39.

At predetermined intervals in the operation of the apparatus, the stud I93, or the stud I94,

engages the end I92 of the trip lever 99 rocking 98 of lever 99 is forced against the end 91 of the lever 94 rocking the lever 94 counter-clockwise, as viewed in-Figure 3, about its pivot against the-action of spring 98. This movement disengages end 93 of lever 94 from the notch 9I of disk 82 thereby initiating. rotation of the shaft 65. .After the tripping action of lever 99, lever 94 is immediately returned to its normal position, under the influence of spring .96 in time to permit end 93 of the lever 94 to engage notch 92 of disk 82, thereby restricting .the rotation of shaft 65 to only one-half revolution.

It will be noted by reference to Figure 6 that there are twice .as many feed pins 61 on feed 'roll I56 as there are feed hole punches 1. Inas- Start-stop mechanism- The starting and stopping of the punching and tape feeding mechanism is controlled by a magnet II9 (Figures 2 and 4). The magnet H9 is secured to a bracket III which in turn is secured by a bracket II2 to main-frame-top-plate 2. As more clearly shown in Figure 2, magnet I I9 is provided with an armature lever I I3 pivoted at II4 to bracket III. One end of armature lever I I3 is provided with a hook or latch II5 which engages one of two peripheral notches: H3

and I I1 on start-stop cam 69. A spring I I8 hav-,

ing one of its ends connected at II9 to armature lever H3 and its other end connected to spring post I29 fixed to bracket III normally tends to revolve lever H3 in a' counter-clockwise direc tion about pivot II4 thereby holding lever II3 away from or out of contact with magnet II9 when said magnet is deenergized; and holding the hook II5 of 'the lever H3 'in engagement with pe ripheral notch H6 or II1, as the case may be,

in start-stop-cam 69.

Now, when magnet H9 is energized it attracts armature lever -II3 causing said lever to revolve about pivot H4 in a clockwise direction against the action of spring H8 and thereby disengaging latched end II6 of lever II3 from notch H6 or H1 in start-stop cam 69, allowing said cam to rotate under the influence of the friction clutch mechanism 69. As the cam 69 rotates, the sleeve 49 and the operating cam 39 alsorotate. The punching and feeding operations are then performed under the control of the cam 39 as described above. As will appear hereinafter, the rotation of the operating cam 39 is limited'to onehalf revolution.

Selector mechanism Referring to Figure 4, immediately below the punches 6 and having abutting relation therewith are a plurality of punch interference bars I21 (Figures 3 and 4), one of such interference bars being provided for each punch 6. The interference bars I 21 are supported on bottom plate I8 of reciprocating punch plate assembly I5 by means of trunnion like pins or projections I28. To compensate for the compactness of the group of punches 6 and the necessary spread of bars I21, the latter are provided with integrally formed compensating arms I29. This spread of the bars I21 is necessary to provide sumcient room for mounting the selector magnets hereinafter referred to. The compensating arms I29 are suitably guided in a guide plate I39 located below guide plate 5 and secured to the standards 3 and 4.

Suitably positioned in main-frame I are a plurality of selector magnets I3I (Figures'3 and 4), one such magnet being provided for each of the punch interference bars I21. Magnets I3I are secured to supporting brackets I32 which in turn are fixed to supporting bars I33, I34 and I35. Associated with each magnet I3I and pivotafiy mounted on an appropriately located shaft I36 is a bell crank lever I31, each lever comprising an armature arm I38 and a punch blocking arm I39. Each arm I39 is bent at its end I4I so as to form a blocking means for obstructing the movement of the particular punch interference bar I21 associated therewith. Backing up the ends I4I are arrestor bars or punch abutments I42, suitably fixed at their ends to the selector casing walls.

Each bell crank lever I31 has associated therewith a spring I43 one end of whichis secured to the end I4I of the blocking arm I39 and the other end to an adjusting screw I44, suitably mounted on one end of a bracket I45 fixed to the end I46 of bracket I 32.- Appropriately mounted to the other end of each bracket I45 and adjacent to the free end of the armature arm I38 of lever I31 is an adjusting screw I41.

When the magnets I3I are in their normal condition, that is, deenergized, the springs I43 rotate the bell crank levers I31 about shafts I36 until the armature 'arms I38 engage the adjusting screws I41. When a magnet I3I is energized, it

attracts the armature arm I38 of the associated bell crank lever I31 causing said lever to rotate about shaft I36, in the opposite direction against .the action of spring I43, thereby causing the blocking end I4I to be .introduced between the end of punch interference bar I21 and punch abutment I42. The magnets I3I are selectively controlled by operation of the keys on a keyboard.

Keyboard The keyboard I59 (Figures 10 and 11) com- ,prises a top plate I5I and a bottom plate I52, held in spaced relation with respect to each other in any suitable manner, and a series of rows keys I53.

The keys I53 are suitably supported for axial movement in the keyboard top and bottom plates II and I52, respectively, and each key is provided with a latch I54 formed integrally therewith and a key top I55 on which is appropriately indicated the letter or figure designating the individual key. Enveloping the shank of each key and confined between the top plate I5I and key top I55 is a helical spring I56, normally maintaining key top I 55 in spaced relation with respect to top plate I5I. This spaced relation is limited by the cooperation of the latches I54 with suitable stops I51 which may be fixed to, or formed integrally with, the top plate I5I. The openings I58 in the bottom plate I52 are elongated to permit the reception of the latches I54 of the keys.

Positioned between plates I5I and I52 and havshown in Figure 10, and each pair of vertical rows represents the letters of the alphabet preferably disposed so that each row contains one-half of the alphabet consecutively arranged from top to bottom, the left hand row of each of said pairs embodying the first half of the alphabet and the right hand row embodying the last half of the alphabet. The seventh to the eleventh rows, inclusive, have one slide member each. The seventh row contains four keys, the key tops of which are labeled, C, O, H, L designating the words, Close, Open", "High, Low, respectively. The eighth, ninth and tenth rows contain the numerals 1 to 9 inclusive and 0. The eleventh or extreme right hand row contains the fractions A, A3, 'V and also three blank keys. The top blank keys I6I are release or unlatching keys, hereinafter described, there being one such key for each slide member I60. The depression of any key in the right hand or fraction row of keys except the aforementioned top blank key, will initiate the operation of the per'forator as will hereinafter appear. The blank key I62 in the right hand row of keys is provided for the purpose of initiating the operation of the perforator in the event the message to be perforated does not contain a fraction.

The slide members I60 are provided with elongated holes I65 through which the keys I53 extend, as shown in Figure 11. The slide members I60 are normally held in the position shown in Figurell by means of springs I66, each of which has one end secured to a stud I61 on the slide member I60 and the other end secured to a stud I68 fixed to the bottom plate I52. Each spring I66 normally pulls its slide member I60 into engagement with the associated keys I53 and against the stop arm I69 of a bell crank lever I10. It will be understood that there isan individual bell crank lever for each slide member.

Each bell crank lever I10 is pivoted at HI and comprises the aforementioned stop arm I69 and an armature arm I12 to the free end of whichis secured a pole piece I13. Associated with each lever I10 and adjacent to pole piece I13 and in spaced relation therewith is a release magnet I the function of which is to eiTect the release of any depressed or operated key I53, preparatory to making a succeeding selection of combinations. This release operation will be fully described hereinafter.

When any one of the keys I53 is depressed sufficiently, the inclined edge of its latch I54 urges the associated slide member I 60 away from its normal position against the action of spring I66 until the latch has cleared the opposite side of the slide member whereupon the slide member returns to its normal position under the influence of spring I66 and locks the depressed key in its depressed position, preventing the return or release of said depressed key until released by operation of the release magnet I15 or by operation of the proper releasekey I6I, as will be described. I

When a release magnet I15 is energized it attracts the pole piece I13 on armature arm I12 causing the bell-crank lever I10 to rock about its pivot I1I in a clockwise direction, as vie ed in Figure 11, so that'arm I69 urges slide mem er I60 to move against the action of spring I66 suiliciently to permit the disengagement of the depressed key I53. When magnet I15 is deenergized, lever I10 is free to rock in a counterclockwise direction under the influence of spring I66 acting through slide member I60 and arm I69 until the arm I12 strikes an appropriately located stop I16. It is obvious that movement of all the slide members I60 may be effected by means of one magnet I15 and lever I10 of proportionate dimensions. The manner in which the magnets I15 are controlled will be fully described hereinafter.

Appropriately positionedon bottom plate I52 and secured thereto on the side opposite to that on which the slide members are disposed are a plurality of contacts I80 of any well known construction, one such contact being associated with each key I53. The depression of any key I53 closes its associated contacts I80 which is thereby instrumental in completing a circuit hereinafter to be described.

As hereinbefore stated, each slide member I60 is provided with a slide release or unlatching key I6I the purpose of which is to efiect' the manual release'or unlatching of the depressed or operated keys I53. It is quite probable that the operator in making a selectionmight strike or operate the wrong key. In such event the keys I6I aflord a means whereby the error may be corrected. These keys I6I also afford a means of erasing a complete message which has been set up on the keyboard.

Keys I6I are similar in construction to keys I53 except that their latches I8I (Figure 11) are purposely made larger than latches I54 and are so fashioned as to throw or urge the slide members, the elongated holes in which are substantially uniform, a greater distance than do latches I54, thereby allowing any latch engaging a slide member I60 to became unlatched or disengaged therefrom and returning the corresponding key to its normal position under the influence of the associated spring I56.

A key I84 (Figures 12 and 13) the purpose and operation of which will be hereinafter fully described, is provided preferably, though not necessarily, in the fraction row of keys. This key is similar in construction to the keys I53 and I6I with the exception that key I84 is not provided with a latch. In place of a latch the key I84 is provided with a stop portion I85 which bears against a stop I86 to limit the movement of said key. Of course the slide member I60 is provided with a slot I81 for key I84 but only for the purpose of providing clearance or play in case other keys in the same row with key I84 are operated. The hole I88 in plate I52 need not be elongated as in the case of the other keys since there is no latch on key I84. Contacts I90 are arranged to be operated by the key I84.

' Electrical circuits For a proper understanding of the electrical circuits, Figures and 16 should be readto- 1 gether.

The selector magnets I3I which, as hereinbefore described, are. suitably positioned in the main frame I to efiect the selection and storage of the desired combinations of punches are shown diagrammatically in Figure 15. These magnets II3I are electrically connectedto selector relays which are associated with the keyboard. The latter may form a unit distinctly apart from the perforating unit and isolated therefrom, if desired. The selector relays, diagrammatically shown in Figure 16, are shown arranged in rows similarly to the keys on the keyboard.

The selector relays which are controlled by the letter keys will'be referred to hereinafter as the letter relays, the selector relays which are controlled' by the figure" keys will be referred to as the figure relays, the selector relays which are controlled by the C, O, H, L keys will bereferred to as the designation relays and the selector relays which are controlled by the fraction keys will be referred to as the fraction relays. To avoid repetition, I have shown in Figure 16 only two rows of letter relays and only one row of figure relays. ignation relays and the row of. fraction relays. Accordingly, in Figure, 16 the first and second rows comprise letter relays, the third row comprises designation relays, the fourth row comprises figure relays. and the last row comprises fraction relays.

Each of the letter relays as, for example, relay 200 is provided with an energizing circuit which extends from positive battery through the winding of the relay, over the key-controlled contacts I80, common conductor 20I, armature 202 and contact 203 of relay 204 tonegative battery. The function of relay 204 will be fully explained hereinafter.

Each of the letter relays as; for example, relay 2| 0 is provided with an energizing circuit which extends from positive battery through the winding of the relay, over the key-controlled contacts I common conductor 2! I, conductor 20I, armature 202 and contact 203 of relay 204 to negative battery.

Each of the designation relays as, for example, relay 220 is provided with an energizing circuit which extends from positive battery through the winding of the relay over the key-controlled contacts I80. common conductor 22I, armature 222 and contact 223 of relay 204 to negative battery.

Each of the figure relays as, for example, relay 230 is provided with an energizing, circuit which extends from positive battery through the winding of the relay and over the key-controlled contacts I80, common conductor 23I, armature 232 and contact 233 of relay 204' to negative battery.

Each of the fraction relays as, for example, relay 240 is provided with an energizing circuit which extends from positive battery through the winding of the relay, over the key-controlled.

I have, of course, shown the descontacts I80, common conductor 24I, armature 242 and contact 243 of relay 204 to negative battery. As shown in Figure 15, the energizing circuit for the fraction relays divides at the point 248 and extends over a switch 249 through the winding of a relay 250 to negative battery. The relay 250 is' the start-stop relay and controls the operation of the start-stop magnet IIO over -a. circuit which extends from positive battery the operating cam 30 rotates.

In addition to each of the energizing circuits, each of the selector relays such as relays 200, 2 I0, 220, 230 and 240 is provided with a locking circuit as willnow be described.

The locking circuit for each of the letter relays such as relay 200 extends from positive battery through the winding of the relay, back contact 210, armature 21I, common conductor 212, conductor 213 and over circuit breaker 214 to negativebattery.

The locking circuit for each of the letter relays such as relay 2I0 extends from positive battery through the winding of the relay, back contact 280, armature 28I, common conductor 282, common conductor 213 and over circuit breaker 214 to negative battery.

The locking. circuit for each of the designation relays such as relay 220 extends from positive battery through the winding of the relay, back contact 290, armature 29I, common conductor 292, common conductor 213 and over circuit breaker 214 to negative battery.

The locking circuit for each of the figure relays such as relay 230 extends from positive battery through the winding of the relay over back contact 300. armature 30I, common conductor 302, common conductor 213 and over the circuit breaker .214 to negative battery.

The locking circuit for each of the fraction relays such as relay 240 extends from positive battery through the winding of the relay, over back contact 3I0. armature 3, common conductor 3I2, common conductor 213 and over the circuit breaker 214 to negative battery.

It will be noted from the above description that the locking circuit of every selector relay includes the circuit breaker 214. Obviously therefore, opening the circuit breaker 214 will have the eiiect of breaking any locking circuit which happens tobe closed. The circuit breaker 214 is normally maintained closed and is arranged to be opened at a predetermined time in the cycle of operations by .means of a relay 320 which has its armature 32I- secured to the circuit breaker 214 for this purpose. The energizing circuit for the relay 320 extends from positive battery through the winding of the relay and over conductor 322 and contacts 323 to negative battery. The contacts 323 are arranged to be engaged by lug I03 or lug I 04 on the operating cam 30 as will be described hereinafter.

In addition to the locking circuit control armature and contact each individual relay in each row is provided with one or more armatures and contacts for controlling one or more of the punch selector magnets I3I (Figure 15). The number of such arma'tures and contacts associated with any particular relay depends upon the code combination corresponding to the letter or figure which that relay represents.

The release magnets I15, although associated with the keyboard unit, are in no way directly electrically connected therewith. These .magnets are connected in series with .each other over a' conductor 360-to contacts 3BI (Figure 15) which are arranged to be engaged by lug I03 or lug I04 on the operating cam as will be described hereinafter. Operation It will be assumed that the motor is running and that a tape to be perforated has been introduced between punch plate 8 and top plate I I in the usual and well known manner. The motor drives the shafts 49, 4|, I2 and 65 and the parts are now ready for operation.

Referring to Figure 10 it will be assumed that the Q-key of the first set of letter keys is to be depressed followed by a depression of the L-key of the row of designation keys, the 5-key of the first row of figures keys and the %-key of the row of fraction keys, in the order named. It is of course to be understood that since the depression of a fraction key initiates the operation of the perforator it must be the last key to be depressed in each message.

It will be assumed that switch 249 is positioned as shown in Figure 15 to effect the automatic operation of the apparatus. It may, however, as will hereinafter appear, be shifted to the dotted position to dispense with the automatic operation.

The depression of the Q, L and 5 keys closes the contacts I80 in the energizing circuits of the relays 2I0, 220 and 230 respectively, of Figure 16. As hereinbefore described, the energizing circuit for each of these relays includes an armature and a contact of the relay 204, Figure 15. Inasmuch as this relay 204 is at this time deenergized, its contacts 203, 223, 233 and 243 are open and consequently depression of the aforementioned keys does not complete the energizing circuits for the relays but merely prepares such energizing circuits. It will be recalled that 'the keys, when depressed, are latched in their depressed position by the slide members I60. Accordingly, the contacts I operated by the depressed keys are maintained closed until released by automatic operation of the release magnets H or by manual operation of. the release keys IBI.

When the key is depressed it closes it contacts I80 and prepares an energizing circuit for the relay 240, Figure 16, and simultaneously completes an energizing circuit for the start-stop relay 250.. The latter circuit extends from positive battery through the windingof the relay 240, contacts I80, conductor 24I, switch 249, and through the winding of the start-stop relay 250 to negative battery. The start-stop relay 250 energizes and establishes an energizing circuit for the start magnet IIO, this circuit extending from positive battery through the winding of the start magnet H0 and over conductor 25I, armature 252 and contact 253 to negative battery.

Start magnet IIO energizes, moving its armature II3 out of engagement with the start-stop cam 60 thereby initiating rotation of the cam 60 and operating cam 30. These cams'rotate in a counterclockwise direction as viewed in Figure 15. Immediately after the initiation of rotation, the

peripheral stud I04 on the operating cam 30 closes contacts 26I thereby establishing an energizing circuit for the relay 204, this circuit extending from positive battery through the winding of relay 204 and over conductor 260 and contacts 26I to negative battery.

Relay 204 energizes and closes its contacts 203, 223, 233 and 243, thereby completing the previously prepared circuits through the winding of magnet 40I, Figure 15, this circuit extending from positive battery, through the winding of the punch selector magnet 40I, over conductor 402, armature 403 in engagement. with back contact 400, contacts I 80, conductor 2I I, conductor 20I, armature 202 and contact 203 of relay 204 to negative battery. At contact 404, relay 2I0 establishes an energizing circuit for the punch selector magnet 405, this circuit extending from positive battery through the winding of the punch selector magnet 405, over conductor 406, armature 401, contact 404, contacts I80, conductor 2| l, conductor 20I, armature 202 and contact 203 of relay 204 to negative battery. At contact 408, the relay 2I0 establishes an energizing circuit for the punch selector magnet 409, this circuit extending from positive battery through the winding of punch selector magnet 400, over conductor 4I0, armature M I, contact 400, contacts I80, conductor 2| I, conductor 20I and armature 202, and contact 203 of relay 204 to negative battery. At contact M2, the relay 2I0 establishes an energizing circuit for the punch selector mag net 4I3 this circuit extending from positive battery through the winding of punch selector magnet 4I3, over conductor 4I4, armature 4I5, contact 4I2, contacts I80, conductor 2I I, conductor 20I, armature 202 and contact 203 of relay 204 to negative battery.

Relay 220, at its contact 420, establishes an energizing circuit for the punch selector magnet 42I, this circuit extending from positive battery, through the winding of the punch selector ma'gnet 42I, over conductor 422, armature 423, contact'420, contacts I 80, conductor 22I, armature 222 and contact 223 of relay 204 to negative battery.- Referring to Fig. 16 there is disclosed a series of designation relays 220 (four in the present instance) each of which is electrically connected, similarly as just described, to corresponding ones of the upper four groups of punch electromagnets I3I shown in Figure 15. As is well known in the art. permutations of four elements comprising two signaling conditions supply a sufficient number of combinations to take care of ten digits, viz. 0 to 9. Consequently, the right hand punches in the upper four rows of punches 6 (Fig. 15) are not used for price indication purposes. Thus, it is a feature of the present invention to utilize these right hand punches for stock designation purposes.

moving blocking portions I of said levers I37 into the path of punch interference bars I21 thereby setting up a punch arrangement corresponding to the series of code combinations of the message to be perforated, preparatory to performing the perforating operation. A short time after the punch arrangement has been set up the portions 3| and 32 of cam 30 engage the follower rollers 29, 29 of operating levers 26, 26 rocking in these levers about fulcrum 32 and thereby imparting a reciprocating motion to the punch plate assembly I5, to produce a perforated message in tape II. I

After the raised cam portions 3I and 32 have passed under the follower rollers 29, 29the punch plate assembly I5 is restored to its normal position by the return springs 33. Thereafter the stud I04 on cam 30 engages the trip lever 99 (Figure 5) causing the latter to trip the lever 94 and release the drive disk 82. The latter rotates onehalf a revolution in the manner hereinbefore described and operates the feed roll 56 to advance the tape II a distance corresponding to seven units.

- As the operating cam continues to rotate,

the stud I04 engages and closes the contacts 38I, establishing a circuit from positive battery through the windings of all of the release magnets I'I5 (Figure 16) in series and then over wire 30 360, through contacts 36I to negative battery, thereby energizing all of said release magne I15 and operating all the slide members I60, as here-f inbefore described, to effect the restoration of the depressed keys to their respective normal positions.

It will be evident from the preceding description that operation of the relay 204 transferred the setting of the keys to the selector relays and that the relays locked themselves to maintain their setting. Accordingly, as soon as the release magnets I15 have restored the depressed keysto their respective normal positions the operator may proceed to set up on the keyboard the succeeding message to be perforated. In other words the succeeding message may be set upwhile the preceding message is being perforated. Thus an overlap is provided whereby rapid operation is facilitated.

Following this last mentioned operation in the cycle, the peripheral stud I03 on the operating cam 30 engages and closes the contacts 323, thereby establishing an energizing circuit for the release relay 320, this circuit extending from posiiive battery through the winding of release relay 320, wire 322, contacts 323, to negative battery. The release relay 320 energizes and operates its armature 32I to open the circuit breaker 214,

' thereby breaking the circuits which extend through the windings of the operated selector relays and the windings of the operated punch selector magnets. The operated selector relays and punch selector magnets are thus deenergized.

It will be noted that the locking circuit through the selector relays maintain those relays energized and their associated contacts closed until the circuit breaker 214 is opened in the aforementioned manner. It is obvious that the use of the circuit breaker 214 in this manner will preserve the relay contact points of the keyboard unit 70 and thereby simplify and reduce the maintenance of said relay assembly. Circuit breaker 214 is constructed so as to be adapted to resist deterioration by sparking.

Also it will be noted that the period during 75 which the punching operation and the tape feeding operation may take place, extends from the time that the lug I04 on the operating cam 30 closes the contacts 26I until the lug I03 on the operating cam 30 closes the contacts 323.

Non-automatic operation It may be desirable to dispense temporariLy with the automatic operation of ,the keyboard, and to this end, manually operated switch 249 (Figure 15) and key I04 (Figures 12 and 13) 10 are utilized. Should it be desired to dispense with the automatic operation, switch 249 (Figure 15) is moved to the dotted line position, thereby preventing the completion of a circuit through the start-stop relay 250 by the mere operation of a 15 fraction key and necmsitating the further operation or depression of key I84 (Figures 12 and 13) to close contacts I90 (see Figure 16) and allow current to flow from positive battery through winding of relay 450, contacts I90, wire 20 45I, switch 249, winding of relay 250 to negative battery, energizing relay 250 and thereby initiating the operation of the perforator. In this way the depression of a fraction key will not initiate the operation of the apparatus, but will 25 further require the depression of key I84 to start said operation.

Armature 452 of relay 450 (Figure 16) is connected over a conductor 453 to punch selector magnet 454 (Figure 15) in case its associated 30 punch is to be selectively operated instead of being permanently fixed as illustrated by punch 9 in Figures 8 and 9. In either case the operation or depression of key I84 (shown in Figures 12 and 13), and consequent closing of contacts I90 35 will initiate the operation of the perforator to produce a punched record whether or not any of the other keys have been operated.

The pu pose of this sixth punch 9 (Figures 8 and 9) in every seventh code combination is to 40 insert a guide record for each perforation operation, that isto say, whenever key I62 or key I04 is depresed alone a perforating operation will result, in which only one punched hole other than feed holes, will appear in the tape, it being 45 that pierced by punch 9, which may have beeneither slidably mounted in or permanently fixed to punch guide plate 5, as the case may be. This guide hole separates messages and may be used to control operations peculiar to the end or be- 50 ginning of a message.

Itwill be noted that as soon as the last key has been depressed the operation of the perforator'is initiated and the operator is free to proceed in setting up on the. keyboard the succeed- 55 ing message to be perforated, while the preceding operation is taking place. This, as is readily discernible, provides an overlap in the operation of my apparatus whereby its rapid operation is facilitated. 0

It will also be noted from the foregoing description that the perforator consists of two parts namely the main-frame which embodies the punches and selector-magnets, and the recipro cating-punch-plate assembly in which the latter is of the lighter construction and therefore is made the movable unit, thereby also enhancing the rapid operation of the machine.

It is obvious that numerous changes may be made in the details set forth without departure from the essentials of the invention as defined in the claims. Thus, although the invention has been described in ,a specific form particularly adaptable to the perforation of a tape for the transmission of signals for stock and commodity quotation board operation it is obvious that the the invention is not limited to such use. Furthermore, while the perforating mechanism is herein shown as controlled by a keyboard it will be understood that it can be equally well controlled in many other ways.

Furthermore, my invention may be used for controlling a transmitter directly, instead of perforating a tape, by arranging the distributing mechanism to successively transmit code combinations of impulseconditions over a signaling line in accordance with the operation of the perforating magnets. Such an arrangement would provide sumcient overlaps in the transmitting circuit to permit direct transmission of the prepared code combinations without the use of an intermediary tape as has heretofore been found necessary.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of 'the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
