KEYBOARD TAPE-PERFORATOR.

1 ,os5,9s5.

To all whom it may concern Be it known that I, Eowano E. KLEIN- HUHMIDT, a citizen of the United States, residing at New York city, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Keyboard 'lape-Perforators, of which the following is a specification.

My invention relates to an apparatus for perforating tape by means of punches oper ated in combinations or groups, and controlled by selector keys, one for each combination or group, the perforated tape being adapted for use in a VVheatstone or any other telegraph transmitter.

In my application, Serial No. 549,492, tiled Marclrlfith, 1910, I have described an apparatus comprising a key board selective mechanism adapted to set groups of punch controllers, of various arrangements and numbers, corresponding to or representing the letters or other symbols on the key board; and means for actuating the controllers, and through them the punches, .t'or perforating a strip of paper to produce the electrical signal equivalents of the key board characters.

The present invention embodies substantially the same principle of operation of the punches and has for its object to simplify and improve the construction, of the selective mechanism, punch controllers, punches and the variable feed mechanism.

My invention will be understood from the following description taken in connection with the accompanying drawings in which- .Figure 1 is a plan view of the perforator with the rising broken away; Fig. 2, a side elevation; Fig. 3, a transverse section through the key board on the plane of the.

Serial No. 685.013.

Similar reference numerals indicate similar parts in the several views' The perforating apparatus herein described, comprises (1) a key board selector mechanisr-t; (2) perforating mechanism; (3) a variable feed mechanism; and t) a paper control. I will describe these several parts in the order above given.

The key board selector rhechanism.-The

purpose of this part of iny apparatus is to po ition what I ,term' punch controllers, thesecontro'llers being adapted to be moved into the path ofa platen, or a punch head, to engage the corresponding punch to per forate the tape. it comprises a bank of key bars 1, the keys of which are provided with the charactersof a universal key board, and the latter includes an additional bar for extra spacing between messages. All of the ltey bars are fulcrumed near their inner ends on a fixed transverse bar 2. Arranged longitudinally of and beneath the key bars, are notched bars 3 fulcrumed near their inner ends on a transverse bar 4, and retained in their normal positions. in contact with the under edges of the corresponding key bars by springs 5 fixed at one end to the base of the frame. Secured upon opposite sides of each key bar are small guide plates ti, and between said plates the notched bars 3 rest to prevent sidewise movement, each bar 3 having a short projecting-section on its upper edge to pass between the guide plates 6, as shown in F igs. 2 and 3. A transversely extending stop 7 limits the downward movement of bars 3 when depressed by the key bars, and a stop 7"limits the upward movement of the key bars.

The purpose of providing a notched sclector bar instead of notching the underside of the key bar, as in my former application, is to provide for an equal extent of movement of the outer or key ends of the key bars. The key bars 1 have a common fulcrum 2, as above stated, and the guide plates 6 are placed on the key bars at varying d1s-' notched bars and of the key bars, there being one of said T-hars for each punch controller, and a universal bar, shown in Fig.

3, which is adapted to be depressed when I any one of the key bars is depressed. The T-bars are supported by parallel links 9 pivoted to the le s of said bars, the other ends of said links being pivoted on a bracket 10 secured in the frame.

8 is notched to receive a connecting bar 11, only the first and last of said legs and bars and 5, these hats 11 alternate in length to facilitate assembling, and are fulcrumed able link connection, as shown for the purpose of properly positioning the upper ends of the controllers relatively to the punches.

These punch controllers have a vertical' movement through openings in a punch head 16 which will now be described.

The perforating mechanism.The particular perforatingmechanism shown by me, for purposes of illustration, is intended to perforate a tape to be used in a VVheatstone transmitter. As shown, the perforator com- 5 prises two rows of punches 17 and 18 there "being shown in Fig. 3. As shown in Figs. 2

near their inner ends either on the same bar 4 upon which the notched .bars 3 are fulcrumed, or upon another bar'in proximity to the bar so as to insure a substantially equal movement of the punch controllers. Slotted plates 13 (Fig. 3) receive the ends of the T-bars 8 and guide them in their vertical movements when depressed. by the notched selector bars 3, and when raised by the springs 12 attached to them be 0nd the connectin bar 4. By reason 0 links the T-bars 11 will always move in a vertical ath by whichever notched bar 3 a given 'F-bar may be depressed, that is, there will be no tilting of a depressed T-bar when moved by the extreme notched bars.

By having a common fulcrum bar 4 for the selector bars 3 and the connecting bars :11, or by having the fulcrums. in close proximity to each other,' a substantially equal extent of movement of the outer ends of the connecting bars 11 is insured, whether 5 a given bar 11 is depressed by a T-bar 8 That near to or removed from the fulcrum. is, by reference to Figs. 3 and 4 it will be seen that each Thar 8 is adapted to be de- 3 and that when a given T-bar is depressed fulcrum 4 the extent of movement of'the short arms of the bars 11 will be equal whether that bar be connected to the nearest or to the farthest T-bar. This equal ing bars 11 insures an equal movement of all of the punch controllers.

The ultimate work performed by the selector mechanism is to position the punch controllers 1 and .15 connected to the inner ends of the connectin bars 11, as shown in F ig. 5, and arranged in two rows, as shown the parallel being ten ineach row, it being understood One edge of the vertical legs of the T-bars of course that there maybe as many punches as desired according to the code. Between the punches 17 and 18 is a third row 19 for punching a center row 01 perforations adapted to be engaged by the teeth of a feed wheel, hereafter described. A bracket 20, secured to the main frame, is provided with guide holes for the reception of the punches which slide freely therein. The punch head 16 is slidably supported in the gibs21 and is normally held in its retracted position, shown in Fig. 5, by a spring 22, being held against stops 24 on the ends of the gibs.

A die-plate 23, supported on the bracket 20, is provided with holes through which the punches pass after perforating the tape, the bracket 20 being recessed to provide a space for the passage of the tape 24. The normal position of the punch controllersand of the punches is shown in Fig. 5. When a key is depressed, a group of controllers is raised corresponding in number and arrangement to the code symbol of the key struck, so that their upper ends will contact with the punches. when the punch head is brought forward.

To move the punch head forward I provide a solenoid 25 (Fig. 6) the core of which has connected to it one arm of a bell crank lever 26 pivoted on the frame, The

other arm of said lever is connected to the d b H f th be} d l t b main operating lever 27, the latter being presse y a o e no 1e so ec or ars j pivoted on th frame and held in its rei tracted position by a spring 28, (Fig. 7).

ihead 16 (Fig. 5).

cluded in a circuit having a normally open Secured to lever 27 is a stud 29 which passes through an elongated slot 30 in the punch The solenoid 25 is incontact 31. The lower member of this coni tact is connected to, but insulated from, a movement of the short arms of the connectbar 32, similar to the bars 11, and controlled by a universal T-bar 8 (Figs. 3 and 4), so that when bar 32 is depressed the lower contact will be raised and the circuit closed,- energizing solenoid 25. This occurs when any one of the key bars is depressed. The movement of the solenoid core rocks lever 26 and the resulting forward movement of the punch head 16, through lever 27 and stud 29,

forces those punch controllers 14 and 15,

which have been raised. against the ends of the corresponding punches 1'7 and 18 to perforate the tape, there being as many punches operated as there are punch controllers raised. The punches pass through the paper and into the holes in ie die-plate 23. When the depressed key is released, contact "31 is opened-and solcnoid deenergized. Spring spring 28 will restore the main depressed key is-releascd it is restored to its 1 normal position by a spring 5 to the notched selector bar .5 depressed by the key bar; and the T-hars 8 which were depressed are restored to their normal position by the springs 12 acting through the corresponding connecting bars 11. movement of the connecting bars 11 will restore the raised punch controllers l4 and '15 to tlieirnormal position.

In addition to the punches 17 and 18, which make the character perforations, an additional row of punches 1.) is located mid way between the rows of punches 17 and 18. The punch head 16 is provided with a block 33 which impinges against the punches 19 upon every forwardmovement The 1 connected a link 42. and lever 41 has pivoted thereto, a link- L2), the latter having connected to it a pawl 4+ pivoted on an arm 4:5 which is mounted on the stud of feed wheel 46. Pawl --l-l is in the form of a bell crank, and has an extended arm H having its end turned down through a slot in arm 45. A spring H engages the turned down end of arm H so as to normally hold the toe of pawl ii in cngag'cment with the teeth of wheel 5L7. When the pawl is'positioned for operat ingwheel 47, the turned down end of arm 44 strikes the rear wall of the slot in arm 45 and prevents the pawl being thrown too far away from wheel d7. The feed wheel isprovided with teeth on its periphery which engage the center row of pcrfora tions on the tape to feed the latter forward g an amount determined by the throw of pawl of the'punch head for perforating a central row of holes adapted to engage a feed wheel, as will be presently described.

To retract the punches after they have been moved forward to perforate the tape I provide a comb 34, secured to the punch head. As shown in Fig. 5 each. punch has fixed thereto a collar 35 which, when the punches are in their retracted position, rest against a ,stop 36. \Vhen the punches are advanced the comb 3+ is advanced. and when the punch head is retracted, the comb M -is retracted and carries-with it those punches which have been-advanced until the latter are restored to their normal po-.

sition with their collars hearing against the stop-36.

T/w'curiublc feed r/wc/umism. -To adapt my apparatus for codes requiring varying numbers of perforations for the key board characters it is necessary 'that a variable feed be provided. For that purpose 1 connect-with the main operating lever 27, a feed operating lever 34' pivoted on a stud 37'. the

connection being made by a pin 38 on lever 27 engaging a slot 39 in the lever 37, as shown in Fig. 7. The parts are so related to each other that the pin 55 will engage therear wall of slot 39 when lever 27 is re tracted, and after the punch head 16 has been retracted sufficiently to witl'idrnw the punches from the perforations in the tape, tofeed the tape. At its free end the lever 37 has pivoted thereto. a floating lever 40. The lever 40 is connected to a lever 41 by 14. The latter engages a ratchet wheel 47 fast to the feed wheel, and said wheel 17 is advanced on the return movement of the pawl, theextent of such movement being sufiicientto feed the tape an amount equal to the length ofthe last group of perform tions, varying as such lengths vary, and an additional amount to space the groups. This effected as follows: \Vhen lever 37 is moved forward, lever 40 is also moved for\ 'ard with its fulcrum on the pivotal connection with linl; at d the upper end strikes the last one or the punch controllers of the group raised by the selector mechanism.

As shown in Fig 3. the punch controllers 1.) are shortci chat the controllers 14, and the latter are formed with a lateral projection 46 which projection passes through sl ts {i9 (Fig. 8) -when the corresponding controller is raised. The notched selector hars arc so. arranged in the present apparatus that one'of the controllers .15 which operate the punches in making the lower row Of'1NII'l' UI'iIUUHS. is always the last of the group. That is. as arranged thctapc feeds to the left and the groups are read from left to right so that for any given group there will always be a projection 48 raised through onc of the slots 49 in the path of a nose 50 on level" -i().-- \Vhcn the nose .30 contacts with the projection lo on the last one of the controllers 13 of the group, then the lever itl-fulcrums on that projection and the cg'intinucd forward movement of lever :3? moves the lower end of lever-40 to the left. and through that movement the pawl 44 is retracted. or moved to the right. and engages the tccth of wheel 47 when the former comes to rest. \Vhen the main operating lever 27 is moved forward. lever 37 startson its forward movement slightly in advance of the forward movementof the punch head. This slight time interval permits the'nose of lever 40 to reach its final position before a rack ii on the punch head (Figs. 5 and S) reaches the end of its forward movement.

The continued forward movement of the punch head causes the rack 51 to engage the pointed end 40' of lever 40 to lock the lat- .ter in position and to prevent its rebound. W hen solenoid 9.5 is denergized and the punclrhead retracted, lever 40 is released from engagement with the rack 51 and nose 30 strikes aspring stop 52 which forms a fulcrum for lever 40, moving the lower end of said lever at its point of connection with link 42 to the right, and the continued rearward movement of lever 37 causes a forward movement of pawl 44 to feed the ratchet wheel 47 and thereby the feed wheel 46, until the pawl strikes a stop 53. A stop 54 limits the forward movement of lever 37. By proper adjustment of the stops 53 and 54 and proportioning the parts described, the tape is always fed an amount equal to the length of the group of perforations and any additional amount desired to space the groups.

As shown in Fig. 8, I provide a stop 55 with which the nose of lever 40 engages when the space bar of the key board is operated. From the foregoingdescription it will be seen that the farther the nose of lever 40 is moved to the left, the less will be the feed of the tape. 7

As shown in Fig. 7 I attach a spring 56 to lever 4-0 to slightly retard the lower endof lever 40 when it is moved forward and to insure that the upper end of said lever moved forward first. I also provide a back lash pawl 57 for ratchet wheel 47.

To insure positive engagement of the teeth of feed wheel 4.6 with the center row of perforations on the tape, I provide a toothed roller 58 on one end of a lever 59 pivoted at its centerv The teeth of roller 58 pass between the teeth on the feed wheel 46 and force the paper over the teeth of the latter. The lever 59 carries at its other end a pressure roll 60 in proximity to stripper Lcvcr 59 is pivoted on aspring-pressed lever 62 to hold the rollers 58 and 60 to their work.

As before stated the bracket 20 is recessed, as shown in Fig. 5, to provide a space for the passage of the tape back of the die 23. To confine the tape in this space I provide a cover 63 hinged to the bracket 20. VVhenthe tape is to be inserted the cover 63 is thrown back. the space provided for the tape is the width of the tape and .the, latter is therefore pre vented from shifting out of place, thus insuring the proper alinement of the perforations. A chute til is provided (Fig. 2) to receive the punches which fall in a suitable receptacle Q5.

T 110 paper c0ntr0Z.In perforating machines of the character herein described, some provision must he made for proper de- Letters Patent of the When the cover is lowered livery of the tape from the reel. In the present apparatus the roll of tape is supported on a reel 66 freely rotatable on a stud carried by a bracket 67. Rig-idly secured to said bracket is an arm 68 to which is pivoted, at its free end, a swinging arm 69. On the free end of said arm is a roll 70 around which the tape passes from the reel to the perforator. Fixed to the arm 69 is a brake shoe 71 adapted to bear against the periphery of wheel 66 and held in normal engagement therewith by a spring 72. The intermittent rapid feed of the tape draws the arm 69 and the brake shoe 61 away from the reel and as the latter is delicately poised, the tape is unwound until there is slack in the tape when spring 72 causes the brake shoe to contact with the reel, and stop its rotation and prevent an undue amount of tape being unwound'bctween the feeding movements.

As in my former application the selector mechanism is purely mechanical in its construction and operation the punch selectors being operated by a system of levers. The only electrical means employed by me is the solenoid :25, adapted to move forward the main operating lever 27. The parts connected to and controlled by the movement of said lever are purely mechanical in construction and operation. This elimination of wiring systems, motors, clutches, etc., as heretofore employed, greatly simplifies the construction of this class of apparatus and renders unnecessary the employment of expert electricians to repair or put in order.
