ATENT- orrlce PRINTING PERFORATING TELEGRAPH APLARATUS Ross A Lake, Dal: Park, Ill., assignor to Teletype Corporation, Chicago, Ill., a corporation of Delaware Application ay 20, 1939, Serial No. 274,796 17 Claims-f (Cl. ice -11s) The present invention pertains j te printingtelegraph apparatus and more particularly to combination printing and perforating apparatus for the simultaneous preparation of corresponding printed and perforated records. v

The primary object of the present invention is to provide a combination printing and perforating apparatus capable of producing under the control of telegraph signals or otherwise, a

printed record and code combinations of perforations representing the printedfrecord on a single recording medium substantially simultaneously.

vancing or leading side of the lidded aperture so that not only the upper side of the tape'can be determined, but also itsplacement in the tape transmitter can readily be made toagree with the directional movement of the'tape through the transmitter in accordance with the sequence of the message.

-By this method of duce lidded apertures'instead of completely per-- fo'rating it, tape of this variety is particularly useful in connection with a combination printerperforator because the characters comprising the Another objec of the invention resides in the provision of means for producing lidded apertures in a signal control strip and ejecting means for same dually functional to permit advance stepwise as well as reverse stepwisemovement of the strip.

Prior devices of the type according to the pres, ent invention have beenarranged to cut out the perforations completely at a'single movement;

being such that the'punches are utilized to so pierce the material as to leave an uncut portion which serves as a hinge, thus resulting in a hinged lid which will yield to the sensing pins in a telegraph transmitter when the tape is employed for automatic control of signal transmission.

A salient advantage of producing a signal control strip having lidded apertures resides in the facility with which its proper insertability inthe tape transmitter may be determined. With ordinary perforated tape one must be skilled'in reading the code according to which the tape is perforated in order to place the said tape properly and. correctly in the transmitting apparatus. This skill is not required in connection with the use of tape prepared according to the present invention. .With the tape of this invention the lids are slightly in relief on the upper surface as i an incident to the punching operation, and for this reasonthe upper surface of the tape can be readily recognized. In addition to this identify-- ing characteristic is the further feature of provlding the hinged portion of the lid on the adprinted record' may be printed over the' 'lidded apertures and remain fully legible. Moreover, a further advantage resulting from this method of producing lidded apertures in the tape resides in the elimination of the problem of disposition of the waste material. Also, the design of punch blocks and punching structures is greatly sim plified.

Essentially, to enable the preparation of signal control tape in accordance with the present invention, the punch block is modified by having a portion of the metal of the die plate surrounding each hole removed, which permits the corresponding edge of the resultant lid to remain uncut after operation of the punch. In order that the lid may be freed from the die plate to permit subsequent advancement of the tape by the tape advancing mechanism, a stripper or ejector, guided by the die plate and a bracket mounted thereon and operated by aoompression spring, is provided for each punch in the punch block. Each ejector is also provided with a guide for facilitating the back-spacing ofthe tape.

An important feature in the design. of the "punch block for producing signal control strips having lidded apertures is the provision of means for maintaining uniform size and spacing of the tape feed holes.

ing apparatus, wherein printing and'perforating' is performed on the same tape or strip. In addition to the provision of perforated tape having.

lidded apertures, whereby the tape material is preserved so that the surface of the taperemains substantially intact, the printed record appears directly over the lidded apertures and is clearly ,.readable. According to the present invention, a combination printing and perforatperforating the tape to proing apparatus is provided wherein the punch interponents are controlled through the instrumentality of punch controller bell cranks operatively associated with the code bars, in such manner that the selection of the punch interponents is controlled by permitting or preventing under the control of the code bars the movement of the controller bell cranks.

A further feature resides in the provision of a dually controlled printing platen whereby the platen is shiftable manually, independently of the case shift mechanism, to render the platen accessible and readily interchangeable.

Since the disclosure herein set forth is in the nature of an improvement of the printing telegraph receiver disclosed in U. S. Patent 1,745,633,

or similar printer mechanisms operative to prop-,

erly select the various type elements, move the tape forward, move and reverse the inking ribbon (as on a standard typewriter), and shift the platen for figure case characters, only so much of the mechanism of said patent will be hereinafter set forth as is necessary to an understanding of the present invention. Reference may be had to said patent for a full understanding of the printer mechanism not described hereinafter in detail.

The present invention provides perforating mechanism adapted for association with a printer, the purpose of which is to co-operate with the printing mechanism in such a manner as to perforate a tape so as to provide lidded apertures. The printed message corresponding to the perforated record appears on said tape directly over the hinged lids and remains fully readable. Til-1. present invention, of course, is not limited to the type of printer exemplified by the afore-mcn tioned patent, but any printer to which the invention is applicable is contemplated.

As disclosed in the above-mentioned patent, the platen H (Figs. 1, 2 and 4) over which the paper tape passes from right to left is located in the front and central part of the apparatus. However, the platen used in this invention is of different construction, comprising as will hereinafter appear, a cylindrical plunger carried in a rectangular block and shiftable in the manner set forth in said patent.

Arranged above the platen H is the ribbon feed mechanism indicated generally as l3, the left spool only of which is shown in Fig. 1. The inking ribbon I5 is directed in well-known manner over platen II from one spool to the other; automatic ribbon reversing mechanism also being provided. Type bars I 2 are positioned to the rear of the platen and are arranged for striking forwardly and downwardly. Just to the rear of the type bars I2 is a series of notched code bars 16 which in the present instance are substantially semicircular in shape. Actuating bars I4 for operating the type bars I2 are located immediately in front of the code bars l6, and are adapted to be pulled one at a time into the alignment of notches in the code bars l6 when the notches are selectively aligned for a particular character or function. As indicated in said patent, the actuating bars I4 are articulated to the type bars l2 through a gear and rack means. The selecting mechanism for selectively operating the code bars I6 is of the sWord-and-T type, fully disclosed in said patent. Briefly, this selector mechanism comprises a selecting or receiving electromagnet l1 (Figs. 1, 2 and 3), the armature lever 18 of which comprises a selecting arm l9 having abutments 2| and 22 which co-operate with abutments 23 and 24 of a series of swords 25. The armature lever I8 is responsive under certain conditions to the energization of the magnet I! (for example, upon receipt of marking or'current impulses) and under other conditions to the pull of a spring 26 (for example, upon the receipt of no current or spacing impulses), the tension of spring 26 being adjustable by means of screw 21. The swords 25, of which there is a plurality corresponding in number to the series of code bars I6, are brought into operative engagement with the selector arm 19 by their individual operating levers 28 pivoted on a common pivot rod 29. Swords 25 are pivotally articulated'by a socket connection to their individual levers 28. Each of the levers 28 is provided with an'arm 3| and is normally biased in a clockwise direction about the pivot 29 by a spring 32. Arms 3| co-operate with a series of helically arranged projections 33 on a selector cam drum 34, which is frictionally driven by a main operating shaft 35 located in a perpendicular position at the rear and to the right of the code bars IS. The main operating shaft 35 is driven continuously by a motor 36 through a pinion 31, secured to the motor shaft 38, which pinion meshes with a gear (not shown) operatively associated with shaft 35.

As fully described in the afore-mentioned patent, the cam drum 34 is initiated into rotation upon receipt of a starting impulse which causes the de-energization of the magnet 11, thereby releasing the armature lever l8 which then responds to the pull of the spring 26 to rotate the lever l8 inla clockwise direction. Upon this movement, an eccentric screw 4| (Fig. 3) cooperates with a plunger 42 which acts in the manner shown in Fig. 5 of U. S. Patent No. 1,884,743 to release, through a lever arrangement, a stop arm (not shown) to initiate rota tion of cam 34.

The speed of rotation of selector cam drum 34 is synchronized with the speed of code impulsing so that as the armature lever I8 is operated in response to received impulses, a cam 33 acts upon its associated lever 28 to rock it counterclockwise (as viewed in Fig. 2) to bring its sword 25 against selector arm l9. Sword 25 will be swung clockwise or counterclockwise, depending on whether abutments 2| and 23 or 22 and 24 co-operate; for example, if abutments 2| and 23 co-operate, then the sword 25 will be swung in a counterclockwise direction and will assume the position shown in Fig. 2. On the other hand, if abutments 22 and 24 co-operate, then sword 25 will .be swung in-a clockwise direction to assume the opposite position. After the sword 25 has been set in accordance with the nature of the signal impulse and the cam 33 passes out of operative engagement with arm 3|, the lever 28 will be actuated in a clockwise direction by its spring 32, carrying its associated sword 25 along with it to impinge the sword 25 against arm. 43 or 44 of a T-lever 45 pivoted at v46, thus rocking the T-lever 45 in a clockwiseor counterclockwise direction. Each of the T-levers 45 is pivotally articulated to a code bar l6 so that when a T-lever 45 is actuated-in a clockwise or counterclockwise direction, its associated code bar is actuated leftwardly or rightwardly, respectively, on studs 41 and 48. Accordingly, with the selecting mechanism just described, the code bars |6are set selectively in their rightward'or leftward positions in response to the-impulses of a code signal.

As described in Patent 1,745,633, the setting of the code bars-l6 is maintained during the printing operation by a detent or locking means. Ac-

cordingly, a locking bar 49 is provided which cooperates with beveled notches 5| on'code bars l6. Bar 49 is pivotally mounted and is moved into and out of engagement with the code bars l6 as the striker bar or operating bail 52 is raised and lowered. The bail 52 is operated by a cam (not shown) on the main. shaft 35, in a manner described in Patent 1,745,633. When the bail 52 is in its lowermost position, it co-operates with the beveled edges 53 of the bars l4 and 49 to hold such bars out of engagement with the code bars l6 so. that the code bars |6 may be readily shifted in accordance with the operation of the selector mechanism. -When the bail 52 is operated upwardly to perform a printing operation, the bars l4 and 49, due to the beveled edge 53, are permitted gradually to be actuated toward the code bars |6 by their individual springs 54. The actuating bars M are provided with a hook portion 55 which co-operates with the bail 52, which in its upward movement engages said hook 55 to lift the actuating bar I4, which through the rack and pinion engagement with the type bar causes the type bar to rotate about its pivot to bring the type face downwardly to impinge upon the platen The locking bar 49 is not provided with a hook portion 55. Its function is merely to rock on its pivot toward and away from the code bars I6 under the control of the bail 52 to lock the code bars IS in their... set position during the printing operation.

wise direction by individual springs 61. springs 61 associated with the bell crank levers According to the present inventionthe locking bar 49, while held in its position away from the code bars |6 when the bail 52 is in its lowermost position, co-operates with a series of hell cranks 56 (Fig. 2) to hold said bell cranks in counterclockwise position. Bell cranks 56 are provided with shouldered portions 51 through the instrumentality of which the bell cranks 56 are permitted or prevented by code bars I6 from rotating to their clockwise position. That is, if any one of the code bars H5 is set in the position indicated in Fig. 2,and the locking bar' 49 is permitted to enter the V notch, the bell crank 56 associated therewith is blocked through the impingement of shoulder 51 uponthe end of' the associated code bar l6. On the other hand, if a code bar |6 assumes its leftward position, the bell crank 56 associated therewith would not be blocked, but would rotate clockwise in response to spring tension hereinafter indicated and follow the movement of the locking bar 49.- As viewed in Fig. 1 it is observed that there is provided a bell crank 56 for each of the code bars l6.

Co-operating with each of the bell cranks 56 is a vertical lever 58 pivoted on a common stud 59. The upper end of each of the levers 58 cooperates with an arm of its associated bell crank 56. The lower ends of levers 58 co-operate with a corresponding series of hell cranks 6| pivotally carried on a common shaft 62. Levers 58 and 6| are pivotally mounted on-a bracket 63 secured to base plate 64. The series of hell crank levers 6| co-operates with a corresponding series of" bell crank levers 65, pivotally supported on a pivot stud 66 secured to the bracket 63. The bell crank levers are normally urged in a clock- The 65 also serve to impart, through their co-operative relationship, rotational movement to levers 6|, 58, and 56. The depending arms oi bell crank levers 65 are provided with enl'arge'd portions which fit into corresponding notches in a series of interponents 68 (Fig. 4), whereby the bell crank levers '65 are pivotally articulated to the interponents 68. Interponents 68 are slidably arranged in a cradle 69 pivoted at 1| to the bracket 63 and are provided near the left-hand upper edge with a cut-away portion 12 adapted to clear associated punches 13 when said interponents are in a certain operative position. Interponents 68 terminate at the left ends thereof with an enlarged portion 14 whereby they are adapted to co-operate with the punches 13 when the interponents 68 are operated to their rightward position, as viewed in Fig. 4. Cradle 69 is provided with a projection I8 (Fig. 12) adapted to co-operate with a feed hole punch 88 to invariably perforate a tape-feed hole in the tape I24 for each operation of theperforating mechotally connected an extensible link indicated generally as 16; one end of link 16being pivoted at "to arm 15 and'th'e other end of link 16 be ing pivotally connected at 18 to a perforator operating lever 19. In the present form of the invention, the link 16 comprises one part 8| pivthe feed punch hole.

oted at 11 to arm I and a part 82 pivoted at 18 to the operating lever I9. Parts 8| and 82 are slidably connected and adjustably mounted on clamp screws 83 and 84 disposed in slots 85 and 86' in part 82. Portion 82 of link I6 is provided with a pair of spaced lugs 81 and 88, the portion 8I being provided with a single lug 89 adapted to be positioned between lugs 81 and- 88. In this manner, the length of link I6 may be readily adjusted by loosening the clamp screws 83 and 84 and inserting a screwdriver or similar instrument between lugs 81 and 89 or 88 and 89, depending upon whether link I6 is to be lengthened or shortened, and twisting said instrument until the proper length is attained, whereafter the clamp screws are tightened.

The operating lever I9 is pivotally mounted on a pivot rod 9I supported in arms 92 and 93 of bracket 63. As viewed in Fig. 2, the operating lever I9is provided with an extension 94, at the extremity of which is mounted a cam follower roller 95 which co-operates with the operating cam 96 carried on the main operating shaft 35. A spring 90 acts upon lever I9 to hold cam roller 95 against the periphery of cam 98.

Supported in the bracket 63 is a punch block indicated generally as 91 in which is carried a series of punch elements I3. Each of the punches I3 is provided with an enlarged.sec tion IOI, the upper edge of which co-operates with a stripper member I02 and the lower edge of which co-operates with a backstop plate I03. Stripper member I02 is urged downwardly by springs I04, to thereby hold the punches I3 in their lower positions free of the die plate I05. As shown in the enlarged sectional view, Fig. 5, the punch I3 is shown fitted into a guide plate 98 with its upper face disposed slightly below the upper surface of said guide plate. Disposed above the guide plate 98 is the die plate I05,

shown in plan view in Fig. 6. The die plate I05 is sheared along edge I06 as to remove a portion of the metal surrounding each of the holes I01 and I08; holes I01 being representative of the code punch holes and hole I08 representing When the die plate I05 is arranged above the die plate 98, as shown in Fig. 5, the punches I3, when operated upwardly into co-operation with the die plate I05 (as indicated in Fig. will cut away only a portion of the tape material, leaving a small hinge portion H0 at the left side of the punch uncut (as viewed in Fig. '7), thus forcing the partially perforated lid, formed by each punch, upwardly into the die plateholes. During the punching operation, a slight tearing or shearing occurs at the point I (Figs. '7 and 9) ofthe hinge IIO (Fig. 10), as well as a very slight stretching of the tape material. To limit theclockwise movement of the cradle 69, a stop 39 is provided adjacent the punch block 91. Stop 39 is adjustably carried in cradle 69. a lock nut 40 being provided to lock said stop in adjusted position.

To minimize tearing of the tape material at the feed holes I08, the feed hole punch 80 (Fig. 13) is made slightly shorter at I39; for exam ple .010 inch, so that when the perforator is adjusted to just perforate a feed hole, which is the preferred adjustment, the code holes (produced by the code punches 13) will all definitely be punchedthrough the tape. It is known that due to manufacturing tolerances the code punches "I3 vary slightly in length, and since this variance in length causes these code hole punches to penetrate various distances through the tape, there will result (within small limits, of course) various degrees of tearing at point I20. This, however, is not detrimental in the case of the code holes because the tape sensing pins of the tape transmitter are smaller in diameter than the code holes in the tape. The function of the tape feed holes, on the other hand, is different in that the size and spacing of the feed holes must be practically constant, and it is desirable to minimize as far as possible any variation therein due to tearing at the hinge. It has been found that this manner of punching the feed holes assures uniform and invariable spacing thereof and hence insures proper co-operation with the tape feeding mechanism of both the tape perforator and tape transmitter.

To eject the hinged lid thus formed from the die plate I05, a stripper member I09 is provided to co-operate with each punch I3. Strippers or ejectors I09 are arranged to be guided at their lower ends by the'die plate I05 and at their upper ends by a Z-shaped bracket III attached to the plate I05, and a compression spring H2 is provided for each ejector I09 to urge the ejectors I09 downwardly. The ejectors I09 when in their downward position are adapted to extend slightly below the dieplates I05 so as to insure the ejection of the hinged lid produced in the material or tape worked upon. After ejection in this manner the hinged lids are slightly in relief, as a result of which the upper surface of the tape may be readily determined.

It is understood, that the resultant position of the lid I25 with respect to the strip I24 is dependent upon the properties of the material of which the strip is composed, as well as the thickness thereof. For example, in a paper strip, the lids I25 take the form or position substantially as shown in Fig. 9, due to the inherent characteristics of the paper, such as thinness and resilience. As the quality of the material worked upon tends toward softness, the lids I25 assume a position in relief, substantially as shown in Fig. 8, wherein the plane of the lid I25 would tend toward parallelism with the plane of the body of the material or strip I24.

The tape, after being partially perforated in this manner, passes over a tape feed roller II3 which is provided with a series of spaced feed pins or projections II4 adapted to co-operate with the lidded feed holes formed by the feed punch and die plate. The feed roll H3 is provided with a series of toothed grooves II5 which co-operate with a tape feed pawl I I6 pivotally carried on the cradle 69 in well-known manner. Fixed to the shaft to which the feed roller H3 is secured is a star wheel III (Fig. 1) which cooperates with a detent member II8, pivoted at II9 to the bracket 63, having a spring I2I which urges the detent roller into engagement with the star wheel I. Fixed to the star wheel II! is a thumb portion I22, whereby the feed roller II 5 may be rotated manually either clockwise or counterclockwise. Therefore, to perform a backspacing operation, the thumb portion I22 is rotated clockwise so as to move the tape rightwardly, as viewed in Fig. 5. In order that the perforated tape may be readily moved rightwardly for a backspacing operation, each of the ejector members I09 is provided with a wing portion I23 (Figs. 5 and 11) having an inclined lower edge, so that as the tape is moved rightwardly, any of the hinged lids which may be projecting upwardly at an angle will be cammed downwardly by the wing portion I23 so as to clear the die plate I05.

InFFgs. '1, 8, and 9 is illustrated a portion of the tape printed and/or perforated in accordance with the present invention. The tape I24 is perforated in such a manner that the lids I25 are not completely severed but are hinged or attached at their left sides to the tape material so that when the tape is introduced into a tape transmitter, the sensing pins will force the lids I25 upwardly and the pins will protrude through the opening provided therefor. As shown in Fig. 7, the printing appears directly over the hinged lids as if the tape had not been perforated and is readily legible. In the specific embodiment of the invention herein shown, the perforated code combination is six steps in advance of the corresponding printed character. That is, the code combination represented by the transverse row I26, Fig. 7, corresponds to the letter Q in the word Quick. Of course, it is understood that if a wider tape is provided, the characters printed can be printed adjacent to the transverse row of code combinations of perforations corresponding thereto. It is conceivable that tape having prepunched feed holes would be desirable under certain conditions. In this event, the feed hole I50 (Fig. 7) would be indicated as fully perforated instead of being provided with a hinged lid. Moreover, although in the present embodiment the perforated record precedes the corresponding printed record, it is possible to position the punch block 91 to the right of the platen II, as viewed in Fig. 4, whereby the printed record would precede the corresponding perforated record.

As indicated in Fig. 1 each type bar I2 is provided with two type faces, thus necessitating a case shift mechanism, which comprises means for shifting the platen I I. As shown in Fig. 4 the platen I I is illustrated as consisting of a cylinder capped with a hard rubber (or other suitable) printing surface. Platen II is removably held in a block 99 slidably mounted on a shaft I which, in turn, is slidably supported in brackets 63 and I21. Fixed to shaft I00 is a collar I26 against which the block 99 is held by a spring I28 surrounding said shaft and compressed between block 99 and a shift arm I29 also fixed to said shaft. Block 99 is slidable rearwardly on shaft I00, through the instrumentality of an arm I30 fixed thereto, against the action of spring I28, to bring the platen II from beneath the tape and inking ribbon, so that said platen thereby becomes accessible for ready removability and interchangeability. The platen II is also shiftable under the control of received code signals through the medium of shift actuating bar I 14 and unshift actuating bar I15. Platen II is shown in Fig. 2 in its unshift or letters position. To shift the platen II to figures position, the actuating bar I14 is selected, which when picked-up by the bail 52 is raised to rock lever I16 about its pivot I11 to lower its end I 18 to effect the disengagement thereof from shift arm I29, whereupon spring I19 compressed between bracket I21 and arm I29 causes shaft I00 to be moved forwardly until collar I26 thereon strikes against bracket 63. Since the relation between'shift arm I29 and block 99 is unchanged, due to the compressive action of spring I28, block 99 is shifted with the shaft I 00 to bring platen II into the shift or figures position. To return platen II to the Search R002 letters or unshift position (shown in Fig. 2) the actuating bar I15 is selected, which when raised by bail 52 rocks lever I8I about pivot I82, and in turn rocks member I83 about its pivot I84 to actuate shift arm I29 rearwardly until arm I29 is again latched by end I18 of lever I16. It is manifest that platen II is shiftable under two operating conditions, one selectively in response to received code signals to shift or unshift position, and the other manually through the instrumentality of arm I30 to render the platen I I accessible and interchangeable.

The platen II is in the form of a cylindrical plunger and is adapted to fit loosely in block 99. Platen II is capped with a substantially resilient printing surface so that upon each printing stroke of a type bar, its type face impinges against the printing surface of the platen, causing said platen to bounce and vibrate slightly, thereby disturbing its position and causing it, when it shall have .come to rest, to have changed or altered its angular position somewhat. This action causes the platen II to present a new and/or different angular position to the printing element, thus tending to preserve the printing surface and prolong the life of the platen cap.

General Operation In the operation of the apparatus according to the present invention, the motor 36 is considered to be running continuously, thus rotating the main operating shaft 35. Carried on the main operating shaft 35 are sleeve members rotatably associated therewith through clutch members, as disclosed in Patent 1,745,633, which sleeves are normally held against rotation. The selector magnet I1 is normally energized so that upon the receipt of a start impulse of spacing nature, the magnet I1 is de-energized and its armature lever I8 is released under the tension of spring 26 whereby the stud 4| thereon urges the plunger 42 leftwardly to release through a series of levers (not shown) the sleeve members on the shaft 45 for rotation in timed relation to each other. As indicated in the Patent 1,745,633, the cam drum selector 34 is released for rotation so that the cam projections 33 thereon operate levers 28 in such a manner that through the co-operation of selector arm I9 therewith the swords 25 are caused to abut said arm I9 and are actuated to one or the other of their selective positions. The operative relationship of the abutments on the swords 45, and selector lever I9 are determinative of the positions of said swords to operate the T-levers 45 to one or the other of their operative positions, the T-levers in turn actuating the code bars I6 to their rightward or leftward position in accordance with the received code combination.

In timed relation with the rotation of cam drum 34, the sleeve carrying the cam (not shown) for performing the several functions of the printer and the operating cam 96 is initiated into rotation. The cam (not shown) operates through mechanism, not here shown but described and shown in said Patent 1,745,633 to reciprocate the bail 52 which, on its upward movement, permits the actuating bars I4 to respond to the pull of their individual springs to be urged into engagement with the code bars I6, one of these actuating bars finding an alignment of slots or notches in the code bars I6 and thus traveling or rotating farther so as to bring its hook portion 55 into the path of the ball 52, so that the bail 52 is in its upward movement,

picks up the hook portion 55 and raises the selected actuating bar to effect rotation of the type l ar I2 associated therewith through its rack andpinion connection. The type pallet on the type bar I2 is therefore caused to impinge upon the platen II to print a character on the tape interposed therebetween, at the same time causing the platen II to alter its printing position somewhat.

Simultaneously with the actuation of the type bar for printing a character through the operation of the actuating bar I4 by bail 52, the locking bar 49 is permitted to respond to the pull of its spring 54 so that the upper edge of the locking bar 49 moves into the V notches 5| in the code bars I6. In so doing, the levers 56 are permitted to follow this movement of the looking bar 49 in response to the action of spring 61 (Fig. 1). However, when any one of the code bars I6 is in its rightward position, the shoulder 51 of lever 56 will strike against said code bar and the corresponding bell crank lever 56 will be blocked against movement. Therefore, the levers 58, bell crank levers 6| and 65, and interponents 68 associated therewith will have no motion or movement imparted thereto and will assume the position opposite to that shown in Fig. 4, that is, with the portion 14 of interponent 68 in register with the punch I3. However, when any one of the code bars I6 is in its leftward position, the shoulder 51 of the lever 56 will not be blocked by its associated code bar I6 and will be permitted to rotate in a clockwise direction under the action of spring 61 through the interconnected levers 65, BI, and 58. This movement will cause the interponent 68 (Fig. 4) associated therewith to be actuated leftwardly to bring the portion I4 of the interponent 68 out of register or alignment with the punch 13. In proper timed relation with these operations, the cam 96 for operating the perforator will actuate the perforating lever I9 clockwise, as viewed in Fig. 4, so that through the link I6, the cradle 69 will be rocked clockwise to bring all of the interponents 68, which have not been moved, into engagement with their respective punches I3, thus urging said punches upwardly through the tape. As the cradle 69 is permitted to rock backward to its counterclockwise position, the stripper plate I64 acts to withdraw the punches I3, and the ejectors I09 act to expel the hinged lids from the die plate I85. Thus, there is produced with the present invention a printed and perforated tape, as shown in Fig. 7.

Modification A modified form of ejector or stripper is shown in Figs. 14 and 15 and comprises flat spring material so conformed as to have a portion I3I attached to the'die plate I32 by screws I33. Integral with base portion I3I are a plurality of projections (equal to the number of holes in the die plate I32) comprising a stem portion I34, a flat annular portion I35 and a projection I 36. The projection I36 is analogous in purpose to the wing I23 of the form of ejector shown in Fig. 5.
