KUROWSKI, OF BROOKLYN, -NEW YORK, ASSIGNOR TO UNDER-WOOD EL- LIOTT FISHER COMPANY, OF NEW YORK, Y., A CORPORATION OF DELAWARE COMBINED TYPEWRITING. AND

Application filed July 22,

This invention relates to combined typewriting and card-perforating machines, and particularly to means whereby, for joint op eration of a typewriter and card-perforator,

the operation of any typewriter-key toprint is translated and transmitted to the perfo rator as one or more punch-selecting or operating impulses. An object of the invention is to accomplish this by devices that are wholly mechanical as distinguished from the heretofore used means. which involve the use of electromagnets, circuits, contacts, etc. By means of the selected punches, holes are subsequently punched in a card, the location of 5 the holes in the card being descriptive of the characters printed by operation of the typewriter-keys.

One advantage resulting from the provi sion and use of the aforesaid wholly mechanical devices is an assurance of positiveness in the operation of the punch-selecting or punchoperating elements by the typewriter-keys. With the heretofore used electrical devices, this assurance has been lacking on account of the lack of absolute certainty in the operation of said electrical devices. For example, there might be defective contacts or defective operation thereof. By the operation of the typewriter-keys these contacts were actuated to close electrical circuits for causing the energization of electromagnets which, in turn, actuated the punch-selecting ele ments of the perforator. The failure of a contact or any other part of the electrical de- 5 vices to function would result in improper punching, if, as-is very likely, such failure escaped the immediate notice of the operator. The invention is particularly useful in a machine of the type shown in my co-pending application, Serial No. 48,723, filed Au ust 7, 1925 (now Patent No. 1,683,979, dated eptember 11, 1928). Such a machine, including the well-known Underwood typewriter and Powers key-punch, both of which are modi- 15 fied by an illustrative application of the present invention, is herein described and shown. The regular Powers key-punch, which will hereinafter be called the cardperforator, is of the type shown in Patent No. i0 1, 287 ,706, to W. W. Lasker, dated December CARD-PERFORATING MACHINE 1926. Serial No. 124,147.

17, 1918. Althou h the machines shown in my aforesaid pen ing application and in the present application are in the nature of the work they perform, only one adaptation of a combined typewriter and card-perforator, it will be understood that the invention is not limited to such an adaptation, and may be applied to other combinations of typewriting and card-perforating mechanisms.

The punches of the perforator herein shown are arranged, as usual, in forty-five parallel columns, each column having twelve punches. \Vhen acard is in position to be punched, each punch in each column registers with a corresponding hole-space in the card.

' Included in the usual punch-selecting means there is, for each column of punches, a corresponding column of settable pins. Each pin is in longitudinal alignment with its punch, and the lower end of the pin is normally separated from the upper end of the punch by a gap. To select a punch, and thereby make it effective to perforate a holespace in the card, the settable pin for said punch is depressed and latched in its depressed position, so as to close the aforesaid gap.

The usual die-plate, which co-operates with the punches, is movable up and down with the card. During the upward move ment, the selected punches, reacting against the pins that arefset against them, perforate the card, the punches not selected being pushed idly upward by and with the card.

The usual stripper-plate guides the lower portions of the punches and moves with the die-plate from which it is. separated by a gap which receives the card. During the downward movement of the die and stripper plates, which immediately follows their upward movement, the card is stripped from the punches. Each punch has at its upper end a shoulder, and, while the card is being stripped from the punches, the shoulders of said punches react against a fixed plate, which also guides the upper portions of'the punches.

To depress the pins, there is provided for each pin-position in a column the usual pinsetting plunger. In the present case there are twelve such-pin-setting plungers, and they are arranged in a column which coincides with the arrangement of a column of pins. The column of pin-setting plungers is mounted in a movable carriage, by means of which the column of plungers may be moved to register with any column of pins. When they so register, the corresponding pins and plungers are in longitudinal alignment, and their adjacent ends are separated by a small clearance to assure free movement of the carriage.

In the regular card-perforator the plungers are actuated to set pins, by key-controlled means, which are part of the regular perforator, and which also actuate an escapement-mechanism, whereby the perforatorcarriage, under the pull of a spring-motor, is automatically shifted, so that the column of plungers will register with column of pins.

The purpose of combining the perforator with the typewriter is that the operation of the typewriter-keys to print shall also set the pins of the perforator, so that the holes corresponding to the characters typed may be punched in a record-card. These perforated record-cards are used in the well-known processes of mechanical accounting. In the adaptation of the combined typewriter and card-perforator herein shown, the typing is done on the record-card, and produces a heading on said card which is descriptive of the holes to be punched in the card. To insure that the positions of the typewriter and cardperforator carriages shall always be in correct relation to one another, the carriages are positively coupled together, as shown in my.

aforesaid co-pending application, Serial No. 48,723.

After the heading has been typed, the card is removed from the typewriter and presented against feed-rolls of the perforator. Upon depressing the usual key, a machine-cycle of the perforator is effected, which causes the feed-rolls to draw the card into punching position, and also causes the card to be punched according to the pins that were set by the operation of the typewriter-keys. After the perforating cycle; the perforatorpins that were set are automatically restored during the return ,of the carriages to their starting positions, and the machine is ready to type and punch another card.

Some alphabetical characters and other symbols mustnecessarily be represented by more than one hole in a card-column, because a card-column has only twelve hole-positions, which are exceeded in number by the total number of characters printed. In carrying out that part of the invention, which is directed toward means whereby the operation of the typewriter-keys may actuate the pinsetting plungers, there are provided first of all mechanical translating means, whereby the succeeding only the pin-setting plungers corresponding to any operated type-key are caused to be actuated. The typewriter-keys, as usual, are mounted on key-levers.

A selection of the pin-setting plungers to be actuated is best accomplished by means which include a number of what may be called selector-members, which have edges that extend transversely of and underlie some suitable part of the typewriter type-actions. In the present case there are twelve such selector-members, one for each pin-setting plunger, and they underlie the typewriter keylevers. A material edge that overlies and extends transversely of the edges of the selector-members will engage and displace only certain ones of the selector-members, if a suitable portion of and below the edge of each selector-member that is not to be engaged by said material edge is cut away. For example, the letter M is represented in the card by the eleventh and twelfth hole-positions, and, therefore, when typing the letter M, .the eleventh and twelfth selector-members must be actuated. In this case each of the other selector-members has its edge cut away where the aforesaid material edge related to the M-key would otherwise engage it, the cutaway portion forming a slot that clears the material'edge as it moves to displace the active selector-members. Each key has its own aforesaid material edge, which is preferably embodied in an interponent between the keylever of said key and the edges of the selectormembers.

In this manner the operation of a key is translatedinto the displacement of one or more selector-members, each of which corresponds to a pin-setting plunger. The invention further provides means whereby said displacement is positively transmitted to said plungers, which are thus operated to set the corresponding pins. It is a feature of the invention that no part of said transmitting means is carried by the perforator-carriage, and there is therefore no tendency to impede the free movement of said carriage. Operating contact with the plungers is therefore best made by means of bars, the lower edges of which are adjacent those portions of the plungers with which such operating contact is made. In order that the plungers may be operated irrespective of the position of .the carriage, said lower edges of the bars are nee essarily parallel to and co-extensive with the paths described by the aforesaid portions of the plungers as the perforator-carriage moves from column to column.

In the present embodiment of the invention the perforator is located behind the typewriter with the body of the perforator higher than the typewriter. Operating extensions of the plunger-actuating bars toward the typewriter" are effected by making each of said bars an upper chord of a light frame,

the vertical sides of said frame extending along and running close to the .outer vertical sides of the perforator-frame. Each of the two sides is guided near its upper end for the up-and-down movement of the frame that is necessary to actuate the plungers. This up-and-down movement of each frame is derived from the up-and-down movement of .the corresponding selector-member under the typewriter.

To transmit the up-and-down movment of the selector-members to the plunger-actuating frames, there is provided for each frame and corresponding selector-member a connecting rock-shaft having at each end an.

arm, both arms extending in substantially the same direction. The ends of each arm are connected respectively to the plungeractuating frame and the selector-member. The shafts areof evenly varying lengths, so that the shafts with their arms may be nested one within the other. In the nested arrangement the shafts lie in a. horizontal plane that is preferably below the typewriter and the body of the card-perforator.

The selector-members are preferably in the form of flat light plates and are mounted in guides for an edgewise up-and-down movement. The upper edges of the plates coact with transverse edges of the aforementioned interponents that are actuated by operation of the type-actions, and said upper edges are of a length sufficient to encompass all of the edges of said interponents. The plane in which the aforementioned connecting rockshafts lie coincides approximately with the lower edges ofthe selector-member plates, which are of sufficient vertical depth to allow the plates to be properly guided. The two sides of each plunger-actuating frame are joined by a chord below the body of the per-i forator. A. midway portion ofeach chord is extended edgewise and downwardly in the form of a panel, so that the lower edge there- ,of may be connected to one of the aforesaid connecting rock-shafts. A pin-and-slot connection joins each panel near its lower edge to an arm of said connecting rock-shaft, the

other arm of which is operatively joined to the corresponding selector-member plate by an abutting connection, the end of the lastmentioned arm simply abutting against the lower edge of the plate. The interponents between the type-actions and the selectormember edges are guided in a fixture mounted on a platform that supports the typewriter, the interponents projecting through a'hole in said platform, so that the lower edges of said interponents are below the bottom of the platform, which is separated from a lower platform by an intervening space in which the selector-member plates are arranged side by side. The selectormember plates are supported and guided in a fixture mounted upon the lower platform and project through an opening in said platform, so that the lower edges of said plates are below the bottom surface of said lower 1platform. Against this lower surface, the

arings for the connecting rock-shafts are fastened, the shafts also being below said surface. Both platforms extend from the perforator-supporting frame. A spring is applied to each interponent to hold it in normal position. Suitable springs are also applied to each punch-selecting frame to counterbalance its weight and also the weight of the parts reacting upon said frame. The punchselecting frame springs alsohold the frames and said parts in their normal positions.

A further object of the invention is to provide a simple key-controlled power-drive, so that the fingers of the operator may be substantially relieved not only of the work required to operate the type-actions to print, but also of the extra work involved in simultaneously actuating the pin-setting pliungers by the means herein outlined. A feature of said power-drive i that it may be applied to the typewriter with a minimum number of changes in said typewriter. To this end, there is provided a bar extending transversely of and below the key-levers. This bar is given a continuously and rapidly reciprocating edgewise movement of suflicient extent tooperate the key-levers in a full stroke. This reciprocating movement is best derived by means of the well-known eccentric and coacting slotted arm device, the slotted arm being fastened to a rock-shaft to which the bar is attached by arms. An electric motor drives the eccentric to which it is geared for a suitable speed. Each key-lever has pivot-- ally attached to it a swingable member, a portion of which may, by swinging the member, be interjected into the path of said reciprocating bar, with a consequent displacement and operation of the typewriter key-lever to print. 'F or each typewriter key-lever there is provided an auxiliary key-lever whereby the displacement of the corresponding swing able member into the I ing bar maybe selectively effected. The keys .of these auxiliary key-levers constitute an auxiliary keyboard, and said auxiliary keylevers are so disposed that the auxiliary keyboard is just above the regular typewritem keyboard with sufficient space between the two keyboards to permit free operation of the auxiliary key-levers. The interjectable portions of the aforesaid swingable members can only be fully interjected into the path of the reciprocating bar when the bar is at the extremity of its upward movement. In order that an auxiliary key-lever may be operated path of the reciprocatin an interval between such extremities, a

yieldable operating connection is provided between each auxiliary key-lever and the swingable member of the corresponding typewriter key-lever. v

Qther features and advantages will hereinafter appear.

Figure 7 is a perspective view, showing the power-driven means for actuating the typeactions.

As shown in Figure 1, a typewriter is combined with a card-perforator for joint operation in which a record-card 10, placed around a platen 11 of the typewriter, may have a heading printed near its upper edge by operating the usual typewriter-key-levers 12, which swing about a fulcrum-rod 15 to actuate bell-cranks 16. Said bell-cranks 16, in swinging about a fulcrum 17, operate typebars 18 to print against said card through an inked ribbon, not shown. Every time a typebar 18 prints, the usual Underwood escapemen-mechanism, generally indicated by the.

number 19, is actuated by said type-bar to cause .a carriage 20, in which the platen 11 is mounted, to move a letter-feeding step. The letter-feeding steps are impelled by the usual Underwood carriage-spring-motor, not shown. The key-levers 12 have mounted thereon the usual numeral-keys 13 and alpha I bet-keys 14. In the joint operation of a typewriter and card-perforator, every time a character is typed, certain elements in the perforator are set that subsequently cause perforations corresponding to the character typed to be punched in the card.

The record-card is divided into columns, each having twelve hole-spaces. Since there are approximately forty-two keys in the typewriter, combinations of several holespaces in a column must be used to represent -til the card is free.

some of the characters printed. The recordcard has forty-five columns of such holespaces, and for each hole-space there is a corresponding punch 21 in the perforator, the punches being arranged in columns of twelve each. A side view of one of the columns of punches is shown in Figure 1 Coa'cting with said punches in the punching of a card, is a die-plate 22 having a hole for each punch. The die-plate is included in What constitutes a card-frame 23." Said card-frame also includes a stripper-plate 24, which is separated from the die-plate by a gap, which may receive the card'to he punched. After the heading has been typed upon the card, it is removed from the typewriter by rotating the platen in the usual line-spacing direction un- When the card isfree of the platen, it is slid rearwardly over tablesurfaces 25 and26, that are part of the typewriter-carriage, and into guides 27, one of which is shown in Figure 1. By means of these guides and a platform 28, on which said'guides are mounted, the card is directed toward the first of several pairs of feed-rolls 29, againstwhich the leading edge of the card is presented. The usual" starting key, not shown, is then pressed to initiate an operating cycle of the card-perforator, and, during this cycle, the feed-rolls 29 draw the card into punching position against a movable stop 30. The feeding of the card into punching position occurs during the first part of said cycle. During the last part of said cycle the frame 23, with the card in the aforesaid gap, is moved upwardly to effect punching of the card. In order that a punch may penetrate and perforate a card,'the lower end of a 'pin 35 when interposed in the path of said punch, opposes said punch as it moves upwardly with the card. The pin 35 is interposed and latched in its depressed position. There is one of said pins for each punch and they are arranged in columns of twelve each. To latch the pins in their depressed position, there is provided, for each column of pins, a spring-pressed latch-plate 36. During the aforesaid cycle of the perforator, a main shaft 31 of the perforator makes one complete revolution, and from this revolution the upward movement of the card-frame 23 is derived by means of a cam 32 fastened to said shaft and a rocker-frame 33, which constitutes the connecting means between said cam 32 and the card-frame 23. Punches for which no pins are set are moved idly upwardly by and with the card. Immediately after the upward movement. of the. frame 23 with the card, the frame and card are retracted by the continued rotation of the cam during the remainder of a cycle. During this retraction, the card is stripped from the punches, which have penetrated it, and, during this stripping action, the shoulders of the punches react against a fixed plate 37 which also guides the upper card into punching position. At the beginning of said cycle, the card-stop 30 is withdrawn for a time longenough to permit the passage of the punched card. The punched card is deposited in a receptacle 49 Punchings from the card drop into a pocket 38 attached to the under side of a perforatorplatform 51. To facilitatethe removal of said punchings, the pocket is provided with a hinged flap 39.

Thus it will be seen that the selection of the unches which are to perforate the card is e ected by depressing and latching 'the pins 35 corresponding to said punches. The pins 35 are depressed in one column at a time. To depress the pins, there is provid-' ed a column of punch-indexing lungers 40 arranged to colncide with a co umn of pins. In order that the pin-setting plungers 40 may be moved to register with any column of pins 35,, the are mounted in a carriage, enerally indicated by the number 41. Said carriage is supported and guided by means of rails 42 and rolls When a character is typed upon a card, the punch-indexing carriage 41 must be in a position corresponding to the typing po'sltlon on the card. In order that the positions of the typewriter-carriage 20 and the punchindexing carriage 41 shall always be in proper relation to each other, said carriages are coupled by means of a rack 44 supported on brackets 45 on the perforator-carriage, and a rack 46 supported on brackets '47 on the typewriter-carriage. A .pinion 48 constitutes the coupling means between 'said racks, and is mounted on a column 49 supported by the platform 28. By means .of said racks and pinion the two carriagesalways move in unison.

To secure the proper relative positions I of the type-writer and the card-perforator,

so that they may be coupled by said racks and pinion, the typewriter is supported upon a platform 50, which in turn is supported by the platform .51 of a perforatorframe, generally' indicated by the number 52. A lower platform 53 is provided to support some of the connectlng devices be tween the typewriter-and the perforator, said connecting devices forming a part of the invention to be explained. Said lower platform 53 is separated fromthe platform' 50 by front and rear studs 54. Spacers 55 establish a proper level for the platform '50. The lower platform 53 extends rearwardly as far as the rear edge of the platform 51, from which it is separated at the rear by plunger.

a spacer 56. Suitable bolts 57 secure the usual typewriter-keyboard. Said code is,

also indicated in Figure 6. In order that the operation of any key-lever 12 -may be translated for a pro er selection of the corresponding punch-indexing plunger or plungers 40 to be actuated, there is provided below the typewriter a number of selector-members 58, one for each indexing Each of these selector-members has a horizontal edge 59 that extends transversely of the key-levers 12. Since each of these selector-members 58 corresponds to an indexing plunger 40, a displacement of a selector-member is equivalent to displacing a plunger, if said displacement is transmitted to sald plunger. To selectively displace the selector-members58 by the operation of any key-lever 12, an interponent 60 is provided between each key-lever and the selector-members. A lower edge 61 of said interponent extends transversely of and encompasses the upper edges of all of the selector-members. Each interponent 60, disposed as shown, when displaced by the operation of'its related key-lever, will displace only the selector-members corresponding to said key-lever, if the aforesaid edges 59 of the other selector-members are cut away adjacent the edge 61 of said displaced interponent. Each selector-member, therefore, has a number of slots 65, which clear the edges of all the interponents, with the exception that where an interponent, throughits key-lever,

.is intended to actuate a selector-member,

there is no slot or cutting away of the upin Figure 1, the interponents are in the form of an inverted T, and are guided in a fixture 62 that is supported by the platform 50. A sprin ponent, to ho d it in its normal position in whicha bent-over tab 64, at the upper end of the interponent, bears against the lower edge of the key-lever 12. One end of said spring 63 is attached to -the interponent, and the other 'end is attached to a suitableprojection 65" from the fixture 62. As-shown 1n Figure 1, the lower edges 61 of the inter{ ponents are below the platform 50, which nents an their supporting fixture 62. The

selector-members 58 are in the form of light A 63 is applied to each inter- 126 has. an'opening 69- that clears the interpo rolls 66 pivoted on rods 66 in

fixtures

67 and 68, secured to the lower platform 53, see Figure 5. An opening 69? in said lower platform 53 clears the selector-members, the lower edges 7 O of which are below the platform 53. On the under side of said platform 53, part of the operating extensions from said selector-members to the punch-indexing plungers may be conveniently disposed, as will/be explained.

In order that operating contact may be had with the punch-indexing plungers in any position of the punch-indexing carriage 41, there is provided for each plunger 40 a bar 72. The lower edge'of said bar 72 is aligned to the upper end of its corresponding plungor 40, said upper end being in the form of a bent-over tab 73 of sufiicient width to insure operating alignment at all times with the bar 72. The lower edge of each bar is parallel to, and at least co-extensive with, the path described by the upper ends of the traveling plungers.

The plungers 4O perform the same function as the usual plungers of the regular perforator. In the resent invention they are actuated by the bar 7 2, and each plunger has a retracting spring 74, which holds the plunger in its normal position, in which a shoulder 75 reacts against a composite plunger-spacing plate 76 mounted on the carriage 41, and made of separable members, to facilitate the insertion of the plungers in assemhling.

The lower ends of the plungers are guided by a slotted plate 71, and are preferably free to lag behind the movement of the punchindexing carriage, so that there shall be no tendency, on account of a relatively slow retraction of the plunger, to impede the movement of the carriage. For thisreason the guide-slots of the plate are extended sufficiently toward the left to permit said lagging of the plunger ends, and the plunger-springs 74 are, inclined sufficiently to yieldably hold said plunger ends in normal position against the right ends of the guide-slots, as shown in Figure 5. Each of the bars 72 forms an upper chordof a frame, generally indicated by the number 77. Each of said frames 77 constitutes a stationary train of operating connections between a plunger and a selector member 58. For this purpose, the sides 79 of the frames are directeddownwardly and along the outer side frames 80 of the main 1 body of the perforator. A suitable opening 81 is provided in the perforator-platform 51, to clear the sides 79 of said frames. Below the platform 51 the sides 79 of each frame are joined by a chord 82. A midway portion of each chord 82 extends downwardly and forms a panel 83. A lower portion 84 of said panel 83, like the lower edge of the selector-member 58, is below the lower platform 53, so as to be conveniently adjacent the connecting means between the frames 77 and the selector-members 58. Said connecting means are preferably a series of shafts 85, one for each frame and corresponding selector-member. The shafts are of varying lengths, the shorter one connecting the inner frame with the inner selector-member, as shown in Figure 4, and the longer shaft connectingthe outer frame with the outer selector-member. By thus progressively varying the lengths of the shafts. they. with their connecting

arms

89 and 92 to the frames and selector-members, may be nested one within the other, as indicated in Figure 4. For supporting the shafts, there is secured to the under surface of the platform 53 a bracket 86. Bearing holes for the shafts are in a series of bent-over tabs 87 formed at either end of said bracket 86. The end of each arm 89 is in the form of a bent-over tab- 90 that abutsagainst the lower edge of the corresponding selector-member. Connection between the arm 92 at the other end of the shaft and its corresponding-frame, is made by means of a pin-and-slot connection 93. It will be seen from Figure 4 that an edgewise vertical displacement of a selector-member 58, caused by operating a type-action. causes an edgewise vertical displacement of the frame 77, and consequently of the bar 72, the displacement of the bar 72 being effective to actuate a corresponding punchindexing plunger. The frames 77 are guided at each side at their upper portions by slotted brackets 78, which are attached to the pcrforator side frames 80. The lower portions of the frames are guided by means of slotted plates'81 fastened to the lower platform 53. A spring 88 on each side of each frame 77 keeps the frame in its normal position, in which stop-pins 91, driven into the sides 79 of each frame. engage the brackets 78. One end of each of said springs 88 is anchored to the corresponding bracket 7 8, and the other ends of said springs are attached to the adjacent sides 79 of the frames. The springs 88 also counterbalance the weight of theframes 77 and the train of mechanism between each frame and the levers 12. All of the parts, constituting a mechanical train between the levers 12 of the typewriter and the punch-indexing plungers 40 of the perforator, are to be madeas light as possible, so that resistance against their operating displacement is reduced to a minimum. and for this reason said parts should be limited in size and number as much as possible without sacrificing the rigidity necessary for their positive operation, which constitutes a feature OfthlS invention. For example, the selector-members 58 and the lower panels 83 may have their interior. portions cut out, as indicated by

openings

94 and 94, respectively (see Figure 4):

In the preferred form of the invention,

.from said bar.

power-driven means to operate the type.- actions are provided to relieve the fingers of the operator, not only of the work necessary to operate the type-actions to print, but also of the work involved in operating the punchindexing plungers 40 by the means herein described. As a source from which operating impulses for said type-actions may be derived, there is provided a rapidly-reciprocating bar 95, which extends transversely of and under the key-levers 12. The reciprocating movement of said bar 95 is derived by means of an eccentric 96, which coacts with a slotted arm 97 fastened to a rock-shaft 98, to which the bar 95 is secured by means of arms 99. The eccentric 96 is formed upon the side of a gear 100, which meshes with a driving gear 101 fastened to a shaft 102 of a driving motor 103. To support the gear 100 for rotation, there is provided abracket 93* mounted upon the platform 50, which also supports the driving motor 103. Said gear is preferably made to rotate upon a suitable stud secured in said bracket 93. If said gear 100 is journaled in a bearing hole in said bracket, said bearing hole must be of suflicient length to furnish proper bearing for the journal, which, in that case, is part of said gear. The rock-shaft 98 has its bearings in side frames 109 of the typewriter.

As an operating connection between the reciprocating bar 95 and each key-lever 12, there is pivotally attached to each key-lever a swingable member 104, see Figure 7. Said swingable member 104 has a lower hookshaped portion 106, which, by swinging the member, may engage the bar 95. Said hookshaped portion is normally disengaged To effect the selective engagement of the hook-shaped portion, there is provided for each key-lever 12 an auxili- .ary lever 107. Said auxiliary levers are pivoted on a common fulcrum-rod 108, which is supported by and between the side frames 109 of the typewriter. A stop-rod 110 determines the normal positions of said levers, and a stop-rod 111 determines the extent to which said levers may be rotated. Each of said auxiliary levers is yieldably held in said normal position by means of a spring 112 secured to a bar 113 that is supported by and between the typewriter side frames 109. Suitable bracing means, not shown, may be providedto support the rods 110, 111 and the bar 113 against sagging. The spring-bar 113 may be similarly braced by means, not shown. The outer arms of the levers 107 are formed so that keys 105, mounted on the ends of said outer arms, constitute an aux iliary keyboard above the regular typewriterkeyboard, said auxiliary keyboard being substantially a duplicate of said regular keyboard. The inner arms 115 of said levers 107 are substantially uniform.

of the lever 117 engages the edge of the swingable member 104, and said tab and said edge are drawn together by a spring 119, which normally has the effect of making substantially one lever of the swingable member 104 and the lever 117. The upper arm of each lever 117 has a suitably curved portion 120, which lies in the path of the end of the arm 115, of the auxiliary lever. When said auxiliary lever is rocked, the curved portion 120is displaced by the end of the arm 115, and the-hook-shaped portion 106 is consequently caused to be interjected into the path of the reciprocating bar 95. It is for the reason that the hook-shaped portion can only be interjected when the bar 95 is at the extremity of its upward movement, that the aforesaid yieldable device, including the lever 117 and spring 119, is provided, and said yieldable device becomes effective if the auxiliary lever is actuated in the interval between such extremities. If the upper edge of the bar moves below the normal level of the ends of the swingable members 104, said lower ends or upper edge should be beveled, so that a member 104 may ride over said bar if its hook-shaped portion 106 is in the path of said bar at the beginning of its upward movement. Figure 2 shows an auxiliary lever 107 operated, and the corresponding hook-shaped portion 106 engaging the bar 95 at the extremity of the upward movement of said bar. At the end of the ensuing downward movemet of said bar the relative positions of the involved parts are as shown in Figure 3.

A spring 116 is attached to each lever 117 and keeps said lever with its related swingable member 104 in normal position,in which the lever 117- stops against a pin 114, proj ecting from the side of the key-lever 12. It will be seen that the power-driven means herein described for operating the type-actions may be easily applied to the typewriter with a minimum of change. It will be understood, however, that the invention may be used with any other form of power-drive for operating the type-actions of the typewriter The power-drive herein described is preferred on account of its simple and novel features, which make it economical to manufacture, install and maintain. It will also be understood that a power-drive for the type-actions may be dispensed with, in which print and actuate the pin-setting plungers by means of the regular typewriter-

keys

13 and 14.

case the type-actions would be operated to v A blank card is adjusted to the platen 11, the carriage shifted to the letter-space position for the first character to be typed, the motor 103 started to continuously vibrate the bail 95, and a key 105 is depressed to the Figure 2 position to swing the member 104 that is pendent from the'associated lever 12 into engagement with the bail, to be drawn downwardly to depress said lever, to throw its type-bar to typing position. The depression of the lever 12 engages the tab 64 to depress the interponent 60, which, in turn, depresses one or more selector-members 58 not provided with clearance slots 65. The depressed selector or selectors 58 engage the end or ends 90 of crank-arms 89 to rock shafts 85, to vibrate crank-arms 92 having pivoted connections to the frames 77, to pull the cross-bars 72 thereof downwardly to depress punch-indexing plungers 40 which depress punch-setting pins 35 that become automatically locked in their depressedpositions. The release of the key 105 eifects a letter-space movement of carriage 1 20 and a pin-space movement of the carriage 41 and the several parts of the mechanical train of connections actuated by the key 105 are restored by springs 88.

After typing the last character on the card, a series of punch-setting pins 35 remain locked and in punch-intercepting positions,

so that when the typed card is removed from the platen, the card is fed to the rolls 29 and into the card-punching position under the punches 21, the depression of a trip-key, shown and described in my aforesaid pending application, operates to cycle the shaft 31 and the cam 32 to raise the card against the punches 21, and those punches that are intercepted by the indexed pins 35 are forced through the card to leave perforations, when the card is withdrawn, that are descriptive of the items previously typed on the card. The depression of the well-known. carriage-re turn key, not shown, restores the typewritercarriage, restores the pin-indexing carriage, and automatically releases the indexed pins 35 in a well-known manner.

It will be understood that the punch-indexing mechanism with its counterbalanced trains of connections to the levers 12 may be operated by the manual manipulation of the usual character-keys 13, and that when the power-driven mechanism is employed, the

: keys 105 become the operatingkeys, and the levers 12 become type-bar drivlng levers and not key-levers.
