COMBINED TYPEWRITING AND JARD PERFORATING MACHINE Filed July 1Q 192s 4 sheets-sheet 4 MW WM' Patented June 2, 1931 JUNITED STATES PATENT OFFICE ALFRED G. F. KUROWSKI, OF BROOKLYN, YORK, ASSIGNOR TO 'UNDERWOOD ELLIOTT FISHER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE COMBINED TYPEWRITING CARD-PERFORATING MACHINE Application filed my 1,

This invention relates to combined typewriting and card-perforating machines in which the type-operating keys of the typewriting machine are caused also to select punches, so that, at the completion of the line of typing on the work-sheet or card, a-corresponding selection of punch-controllers is set up, preparatory to punching a card in correspondence with the typing on the same card or on a separate work-sheet. The typewriting machine includes a carriage, and the punch-selecting mechanism also includes a carriage, and bot-h carriages have to be returned to begin a new line of typing and punch-selecting. The carriages are motor-returned. The typewriter-carriage is returned by the same motor that is often provided in atypewriting machine for that purpose. It is usual to provide on the keyboard of the typewriter a carriage-re.

turning key for controlling said motor. One of the objects of the invention is to avoid the difficulty that would arise if the carriagereturning key were operated and the typewriter-carriage returned before the punching of the card.

To avoid this difficulty, the usual carriagereturning key of the typewriter is tempora rily diverted from performing its said function, and instead is connected to cause first an operation of the'punch-operating devices, so that the typewriter-carriage remains stationary at this time notwithstanding the manipulation of said carriage-returning key.- Hence, there can be no carriage return prior to the punching operation. A train of mechanism extends from said carriage-returning key to a constantly-revolving powershaft of the punching mechanism, and clutches said shaft to the. selected punches to cause operation thereof.

A return train of mechanism extends from the punch-operating mechanism back to the typewriting mechanism, to effect automatically a return of the typewriter-carriage under the power of said carriage-driving motor. Hence, the depression of the carriage-returning key of the typewriter first eifects the operation of the punches and then 1926. Serial No. 119,838.

writer-carriage and perforating-mechanism carriage to be returned to normal startin positions.

Another feature of the invention is the provision of means whereby all of the typewriter keys are locked and rendered inoperative during the entire interval in which the carriages are being returned. An advantage of this latter feature is that not only is blurring of the work-sheet by operating the type keys while the carriage is in motion prevented., but errors which might be set up in the perforator setting mechanism by such inopportune operation of the type keys during the return of the carriages, are also avoided.

The features of this invention are particularly useful in machines of the type shown in my co-peuding application No. 48,723, ld August 7, 1925 (now Patent No. 1,683,979,V dated September 11, 1928), wherein a typewriter carriage is mechanically coupled to a perforator carriage so that both carriages .move in unison, and wherein power driven usual 45 columns by means of a ca-rd frame that includes a die plate and a stripper plate, the stripper plate guiding the lower ends of the punches and being separated -from the die plate by a gap which may receive a card to be punched. The upper ends of the punches are guided by properly aligned holes in a fixed plat-e and have flanged heads which normally bear upon the fixed plate.

The card' frame with the card is movable upwardly, and, during the upward movement of the frame and the card, the lower yends of the punches bear upon the surface of the card and the punches are thus carried upwardly toward the bank of settable pins. Wherever a hole is to be punched one'of these pins has been set by depressing and latching it in its depressed position. The set pins oppose the upward movement of the corresponding punches which are thus caused to penetrate and perforate the card. l

Immediately after the upward movement of the frame and card they are both retracted and the card is thereby stripped from the punches which may have penetrated it, the downward movement of the punches being arrested and limited by the aforementioned fixed plate.

Before the card may be punched the settable pins are set in one column at a time by means of a row of pin setting plungers, which moves from colunm to column in escapement controlled steps, each step following the operation of one of a number of plunger actuating keys. Y

To enable the row of pin setting plungers to traverse the bank of settable pins they are mounted in the usual carriagelwhich is part of the perforator mechanism. According to my aforesaid co-pending application, this carriage moves in unison -with the typewriter carriage by means of two racks and an intermediate pinion which couple the carriages. The pin setting plungers are actuated by corresponding electrom'agnets, which in turn are caused to be energized by the operation of the typewriter keys, which closes circuits for the magnets by means of contacts that underlie the keys.

The machine herein described, as an illustrative example to which the present invention may be applied, is used to type a heading on cards, the heading corresponding to perforations that are to be made in the card. These perforated cards, as is well known, are used in making groupings, tabulationsuetc., of the data represented by the perforat-ions.

Simultaneously with the typing of the headingvon a card, pins for the corresponding punches are set in the perforator mechanism', the perforator carriage moving step by step in unison with the typewriter carriage. After a line of data has been typed on a card the card is removed from the typewriter and presented against the usual card feed rolls which carry the card into punching position.

These rolls rotate during a'cycle of the perforator, and toward the end of the cycle after the card has been carried into punching position in the aforementioned gap of the card'frame, the card frame is moved up and down to effect the punching of the card according to the pins thatl were set. After the card has been thus punched both carriages are returned by power-driven carriage-returngnechanism, which is part of the Underwood typewriter.

`Heretofore, one key has been used to initiate a cycle of the perforator to feed and punch the card, and then another key to engage the carriage-return mechanism. If the carriage-return key is inadvertently operated first, the carriages will be returned be.- fore t-he punching of the card has been effected and the setting of the pins in the perforator will be wiped out, because the perforator carriage in its return movement automatically causes the restoration of any pins that were set. Aside from this it is an advantage to avoid the necessity of thus operating two keys. l

The present invention provides means whereby one key efectsthe perforator cycle and then the return of the carriages. `Both functions, by means of the present invention, always occur in proper sequence. y

p There is provided, therefore, an operating key adjacent the typewriter keyboard and preferably mechanical connections from said key to the usual perforator drive-engaging means, whereby a. perforator cycle may be initiated. During this cycle theI usual power shaft of the perforator mechanism makes one revolution, during which, (accordingto this invention) it effectsXthe punching and then causes the return of the typewriter-carriage and the punch-carriage.

The usual carriage-return mechanism of the .typewriter is engaged by releasing the usual spring-pressed carriage-return engaging member. The release of this member causes the usual motor to be started and also causes a simultaneous engagement of the usual clutch, whereby the motor is enabled to drive the typewriter-carriage in its return movement and with it the perforator carriage. The release of this member is effected by a movable arm, the end ofv which, as it moves, tripsthe carriage-return engaging member. This movable arm heretofore has been operated by the so-called carriagereturn key. 'In the presentinvention the movable arm is automatically caused to be actuated toward the end of the perforator cycle, after the perforator mechanism has operated toA feed and punch a card. The means whereby this is accomplished consists preferably of a tappet on the aforesaid main shaft of the card perforator and rotatable therewith, and a trainA of linkage connected to the. aforesaid movable arm that releases the carriage-return engaging member. One end of this train of linkage is disposed to lie in the path of said tappet on the main shaft. Consequently said tappet, during a predeterminable part of its revolution, is effective to displace'the train of linkage and thereby actuate the movable arm an-d release the carriage-return engaging member.

The main shaft, as already stated, makes one revolution for every cycle of the perforator, and the angular initial position of the aforesaid tappet thereon with respect to the train of linkage which it displac-es may be set so that the linkage is displaced at the proper time in the cycle. The rotation of the main shaft also a-ctuates the card feed-rolls and the usual means for raising and lowering the card-frame. It will be understood that other' suitable means brought into action during a perfora-tor cycle may be used to automatically engage the carriage-return means, such other means being within Vthe scope of the present invention.

The actuation of the usual perforator-drive engaging means is, as stated, preferably accomplished by means of mechanical connections from the operating key. The perforator-drive engaging means may be also actuated by the usual electro-magnet operated means controlled by the operating key in the usual manner to be illustrated and described. The typewriter-keys are locked during the return movement of the carriages, by utilizing a key-lock train of the typewriter, partly illustrated herein, of the type shown in the Patent t-o W. F. Helmond, No. 775,331, dated November 22, 1904. This mechanism includes the key-lock-rod that is arranged transversely of the typewriter-key-levers and supported upon pivoted arms, whereby it is enabled to be swung into and out of locking relationship to the usual hook-like projections on the key-levers. The aforementioned carriage-return engaging member, when released, causes a displacement of the train of parts to effect enga-gement of the carriagereturn mechanism, and, by suitable means which in the present embodiment of the invention consist mainly of a link between said train of parts and one of the key-lock-rod supporting arms, this displacement is effective to bring the key-lock-rod into locking relationship with the key-levers. This locking 'f0rator, showing only such parts as are necessary to illustrate the invention.

'As shown in the drawings (Figures l and 2) of the combined typewriting and card-perforating machine, a record card 10 is positioned around a platen 11 of an Underwood type-writer, so that type-bars 12 actuated by keys 13 through the usual type-actions, not shown, may print along a line near the upper edge of the card. The keys 13 are on the usual key-levers 14, partly shown in Figure l. As the keys 13 are operated to print, a carriage 15, in which the platen 11 is mounted, moves in letter-feeding steps impelled by the usual spring-motor 16 and controlled by the usual Underwood escapement mechanism 17. The heading printed on the card is descriptive of items to be represented by holes that are to be lpunched in the card` the holes and their location in the card affording means whereby the cards may be used in the wellknown processes of mechanical accounting.

Simultaneously with each operation of any key 13, a corresponding setting of the card perforator mechanism is effected, so that the aforesaid holes corresponding to the typed heading'may be punched when the typing of the heading has been finished. For punching the holes the card perforator has 45 columns of punches 18. A side view of one of the columns of punches is included in Figure 5. The lower portions of the punches are guided by aplate 19 which is separated from a die-plate 20, by a gap which receives the card 10 for punching. The plate 19and die-plate 2() are part of a card-frame 21 which is movpunch is to punch a hole a pin is set by depressing the pin, and a spring-pressed latchplate 24, of which there is one for each column of pins, holds the set pin in its depressed position by means of a notch 25 formed in each pin. A selected punch reacts against the pin that is set for said punch, in the usual manner to be described to effect the punching of a hole. Each columnof punches corresponds to a. letter-space, and each punch by its position in the column represents a certain, letter or numeral. Some of the characters printed are represented by two punch-positions in a column.

As the characters are typed on the card the corresponding punches are selected by setting the pins 23 in one column at a time as the carriage moves in letter-feeding steps. To set the pins there is provided a column of pin-setting plungers 26 which may register with any column of pins. Each plunger is movable downwardly by means of the usual bell-crank 30, to an arm 31 tQ which the upper end of the plunger is pivotally connected. Each bell-crank 30 is rotated to depress its plunger by means of the usual push-wire 33 contained in the flexible sheath 34, one end of the push-wire pushing against a vertical arm 32 of the bell-crank.

-lVhen the typewriter-keys are operated these push-wires, of`which there is ,onev for each bell-crank 30, are actuated, by means of the usual solenoids, to rotate the bellcranks. The solenoids, not shown, are contained in the casing 35, Figure 2. To enable the operation o-f any typewriter-key to energize a corresponding solenoid, there is provided for each key-lever 14 and operable thereby the usual contact device which is not shown but is contained in the casing 36, Figure 1. When a typewriter-key is operated the related contact device i-s operated to close one or more circuits to energize the corresponding solenoid or solenoids. Included in these different circuits are the wires from the Contact devices in the typewriter to the solenoids of the card perforator, and these wires are gathered in the usual cable 39, Figure 1, that virtually connects the c-a'rd perforator and the typewriter for joint operation.

To enable the pins 23 to be set in one column at a time, the pin-setting plungers 26 and related parts are mounted in a perforator-carriage 40, which traverses the bank of pins 23, the lower ends of the column of plungers 26 passing over the column of pins 23. The perforator-carriage 40 is `guided by means of the-usual rolls 41 and rails 42.

The perforator-carriage 40 is coupled to travel in unison with the typewriter-carriage, so that as a character is typed a pin r pins may be set for the column of punches corresponding to the letter-space on the card of the character typed. To couple the carriages there is provided, as shown in my aforesaid co-pending application No. 48,723, a rack 43 secured to the perforator-carriage 40 by means of brackets 44, and a similar rack 45 secured to the typewriter-carriage 15 by means of brackets 46. A. pinion 47 suitably mounted, as shown in Figure 1, meshes with each rack, and by means of said racks and pinion which are always in mesh, the perf-orator-carriage moves in unison with the typewriter-carriage both in letter-feeding and return directions.

When the typing of the line of data on the card is finished the card is removed from the typewriter by turning the platen with the card counterclockwise, and sliding the card when free of the platen over the table surfaces 48 and 49 into guides 50 (Figure 2) by means of which the card is properly directed toward the first pair of feed-rolls 51. The card having been presented to the feed-rollsso that they are ready to grasp and advance it, as shown in Figure 5, an operating 4cycle of thekperforato'r is initiated. During the first portion of this cycle the rolls 51 andother rolls 52 in train therewith advance the card into punching position within the aforementioned gap in the card-frame 21. The proper punching position of the card is determined by a movable stop 54, which is in position to intercept the leading edge of the card and thereby arrest a further movement thereof The upper rolls 53 are lightly spring-pressed upon the card and the corresponding lower rolls 53a slip idly over its surface when the card is thus arrested.

The feeding of the card into punching position is done, as stated, during the first portion of the operating cycle of the card perforator. During said cycle a main shaft 55 makes one revolution. By means of the usual gearing indicated in Figure 5 this main shaft 55 drives the rolls 51, 52 and 53, the rolls 53, as stated, slipping idly over the surface of the card after it has been arrested by the movable stop 54. During this first portion of an operating cycle a card, left in punching position, at the conclusion of a preceding cycle, is conveyed to a receptacle 56 by `rolls 57 that are in train with the other rolls. During this assage of a card to said receptacle the mova le stop 54 is caused to be withdrawn for a time long enough to permit said passage. During the final portion of the operating cycle an upward movement of the card frame 21 with the card therein causes all the punches, except those punches over which a A pin is set, to be pushed upwardly in an idle movement with the card. Wherever a pin is set the upward movement of the correspondpunch with the card is opposed by the set pin,

and theipunch reacting against the set pin is j thereby caused to penetrate and perforate the l card.

Each of the punches 18 has a head 18"', the under surface of which reacts against a fixed plate 58 while the card is being stripped from the punch. The fixed plate 58 also -guides the upward portion of the punches by means of properly aligned holes therein.

The upward and downward movement of the card frame 21 is derived from the .rotation of the main shaft 55 by means of the usual cam 59, and the usual pivoted frame 60 consisting of a cross-bar 61 with an arm 62 at each end and an arm 63 intermediate said ends. The cam 59 is fastened to the main shaft 55, andy its contour is formed to move the frame 60, and consequently the card frame 21, up and down during the final portion of the operating cycle.

To initiate an operating cycle, which is equivalent to a revolution of the main shaft 55, there isprovided the usual perforator l drive engaging means which are of the type shown in Patent No. 1,352,006 to Wr W. Lasker, dated September 7 1920. Said means include a` driving disk 65 keyed to a continuously rotatable power driven shaft 66 which is substantially in line with the main shaft 4 55. The disk 65 has a number of driving spurs 67, any one of which may colact with a projection from the main shaft 55 to drive said main shaft. This projection is in the form of a retractable pin 68 which is normally held disengaged from the spurs 67 of the disk which rotates idly when not driving the card perforator in an operating cycle. The pin 68 is held in proper relation to the driving disk 65 by means of the usual arm 69 keyed to the main shaft 55. To hold the pin 68 said arm is provided witha counterbored hole which fits the pin andforms a seat through which a shank 70 of the pin passes. The usual spring 71 (Figure 2) urges the pin to move; into engagement with t-he driving spurs 67.

To normally hold the pin 68 disengaged Afrom said spurs 67 and also to disengage the pins from said spurs toward the end of an operating cycle, there is provided the usual cam lever 72 against which a head 7 3, formed on the shank of the pin, reacts. The cam lever 72 is pivotally supported at 7 4 by a post 75.- It will be seen that the pin 68 is freedand escapes to move into engagement with one of the spurs 67 if the cam lever receives an impulse that causes it to be withdrawn for a. moment from the head 73 of the pin.

Included in the usual means for imparting this impulse or movement to the cam lever 72 is the link 76 Apivotally connected to the cam lever at 77. Said link 76 is slidably guided at one end in a slot closed by a pin 78, said pin and said slot being at the upper end `of an upright fixture 79. Another slotted fixture 80 guides the other end of said link 76 laterally and is extended downwardlyto hold one end of a restoring spring 81 which is attached to said link and serves to restore and hold said link 76 and cam lever 72 in normal position.

The usual means described in my aforesaid co-pending application No. 48,723 for actuating the link 76 to initiate a perforating cycle, are shown diagrammatically in Figure 7 and include a lever 84 pivoted at 85 to the perforator frame. To translate a movement of said lever into a substantially endwise movement of the link 76, a pin 86 in said link is provided and co-acts with an inclined cam i of a solenoid-90 which is contained in the casing 35. A circuit to cause the solenoid to be energized may be made by means of contacts 91 which are controlled by a key 92 at the typewriter keyboard.

It is one purpose, however, of the present invention to provide that the link 76 may be actuated by means of mechanical connections, frorn a key at or near the typewriter keyboard. One advantage of such mechanical connections is that their action is more direct and therefore more positive than electrieally operated connections. Another advantage is that mechanical connections cost relatively less to manufacture and maintain.

Still another advantage is that some of the.

parts of the mechanical connections between a key at the typewriter keyboard and the link 76 may be made of parts that are' duplicates of or identical with the parts used in another feature of the invention, namely, the parts which constitute the means whereby the carriage-return mechanism is engaged at the end of an operating cycle of the card perforator.

The usual Underwood carriage-return mechanism has an electric driving motor 95 supported by the typewriter frame 96. By means of the usual gearing housed in the casing 97 said motor is connected toLa shaft 98, to which is secured a driving clutch member 99. l

Toenable the rotation of the clutch lne-1nber 99 to drive the typewriter carriage 15 in a return movement, there is secured to said carriage the usual rack 100 which meshes with a pinion 102. Said pinion 102 is formed on another clutch member 103 which is slidable into and out of engagement with the clutch member`99 along an extension of the shaft 98. It will be seen that when said clutch members interlock themotor 95 can drive the typewriter carriage and the punchselecting carriage. To enable the clutch Y displacement of said member103 to be brought into engagement with the clutch member 99by means controllable from a point near the typewriter keyboard, there is. provided the usual train of linkage 104. One end of said train is connected in the usual manner to the clutch member 103, and at the other end of said train is a bar 105, which projects through a front' plat-e 109 of the typewriter near its left hand side. In the normal position of said train of linkage the clutch members 99 and 103 are disengaged as shown in Figure 1. Said normal position is secured against the pull of a spring 106 by means of a latching edge formed by a notch 107 in the bar 105, said latching edge coacting with the lower edge of a slot 108 in the front plate 109 of the typewriter.

To cause engagement ofthe clutch members 99 and 103 so that the motor 95 may return thektypewriter carriage, the forward part of the bar 105 is slightly lifted. This permits the holding edge formed by the (notch 107 to escape from the front plate 109.

The pull of the spring 106 then displaces the train flinkage 104 and the engagement of said clutch members, as shown in Figure 6, is thereby effected. Simultaneously with the I train of linkage the usual switch contained in the case 110 is closed and the driving motor 95 thereby started. The closing of the switch is ellected by the movement of a bar 101 connected, as shown, to the train of linkage 104.

To enable the carriage 15 to automatically terminate its return movement when it has reached a predeterminable position, the usual means are provided to' disengage the clutchr members 99.and 103 and open the aforesaid switch to stop the motor 95. Said means include an extension of the aforesaid train of linkage 104, said extension including the linkage 111 and terminating in a camshaped end of a dog 112, keyed to a splined rockable shaft 113. Said dog 112 is movable along said shaft with a right hand marginal carriage stop 114 (Figure 1) en the typewriter carriage in a power driven return movement reaches a position determined by said carriage stop 114, a tap-V pet' 115 on said carriage displaces the camshaped end of the dog 112, and thereby effects the restoration of all parts in train with said dog to normal. In this restoration the clutch members 99 and 103 are disengaged and the switch in the case 110 is opened to stop the motor 95. Thus is the power driven return movement of the typewriter and punch-selecting carriages automatically arrested.

During the return movement of the perforator carriage 40, which is driven by the typewriter carriage, all the pins 23 which were set are automatically caused to be restored by said movement. To thus eliect said automatically brought into position so as to effect such displacement during said return movement. The displacement of the lever 27 in turn causes a longitudinal displacement of the corresponding latch plate 24 which is effective to release any pin 23 held by said latch plate. Any pin23 when released is pushed upwardly by means of' the usual spring 29. The settable pins 23 are guided in the usual stationary frames 93 and 94, the

frame 93 .also slidably supporting the latch plates 24.

To engage the carriage-return mechanism by raising the forward end of the bar 105 and thus releasing it in the manner described, there is provided a lever 117, which, in a clockwise rotation thereof, is effective to raise the forward end of said bar 105. To enable said lever 117 to raise said bar, an end 118 of said lever engages a projection 119 of a block 120 that is pivoted on the side of said bar 105 at 121 and has'a counter-weight por'- tion 122, which normally keeps it against a stop-pin.123. The pivoted block 120 is provided so that a retractive movement of the lever 117 is ineffective to raise the bar 105.

Heretofore the lever 117 ha been actuated by means of a key attached-to an extension of said lever, as shown in my aforesaid copending application No. 48,723. For automatically line-spacing the platen 11 during a power driven return movement of the carriage there may be provided the usual means, not shown. Said last mentioned means ma be of the type shown in'my co-pending application, Serial No. 41,507, filed July 6, 1925. (novS7 Patent No. 1,679,727, dated August 7, 1928 According to the present invention, and, in order that a power-driven returnmovement of the carriages shall be initiated automatically after a card-perforator cycle, in an operating cycle thereof, has effected feeding and punching of the card, there are provided means whereby the final, part of a revolution of the main shaft 55 of the card perforator will operate the lever 117 to initiate said return movement. Said means in the illustrated form of the invention includes a lever 125 pivoted to a iixture 126 at 127, said fixture being secured to the perforatorframe, and also includes the connections whereby a movement of said lever 125 is transmitted to the lever 117 as a carriagereturn initiating impulse. The movement of the lever 125 is derived from the rotation of the main shaft 55 by means of tappet 129 that is formed on the end of the arm 69, said movement occurring as said tappet displaces tened to the under side of a platform 133,

on which the typewriter is mounted. Another part of said connections is the lever 134 that is pivoted in a bracket 135 fastened to the frame of the card-perforator. The lever 125 is connected to the levcr 134 by a link 136, the lever 134 in turn being connected to the bell-crank 131 by a link 137. A link 138 finally connects the'bell-crank 131 to the lever 117.

VIn order that the lever 117 shall release the bar 105 at what is substantially the end of a revolution of the main shaft 55, the initial normal position of said lever in relation to said bar, with a corresponding normal position of the train of parts connected to said lever 117, is substantially as shown in Figure 1. This initial position is held against the pull of a spring 139 which is provided to retract the lever 117 and its train of parts, one end of said spring being conveniently applied to the link 137 and the other end being anchored to a bracket 140 fastened to the under side of the platform 133. To hold said initial position against the pull of said spring, the corresponding initial position ofv the tappet 129 on the arm 69 of the main shaft 55 of the. cardperforator is as shown in Figure 1. In this position the pull of said spring-reacts, through the lever 125, upon said tappet.

At the beginning of a revolution of the main shaft 55 in an operating' cycle, the tappet 129 over-rides the end 130 of the lever 125. As said tappet 129 escapes, the train of parts actuated by said lever 125 assumes a position, shown in Figure 4, under the influence of the spring 139. This position is determined by a stop-pin 141 against which the lever 125 strikes. During the final part of the revolution of the main shaft 55 the tappet 129 displaces the end 130 of the lever 125, and thereby rotates said lever counterclockwise to its original position, as shown in Figure 6. A corresponding rotation is transmitted, as stated, to the lever 117 which, in the mannerdescribed, initiates a return movement of the carriages.

To initiate an operating cycle of the cardperforator, the link 76 is actuated to cause the withdrawal of the cam-lever 72. from the head 73 of the pin 68. To thus actuate said link 76 by means controllable from a point near the typewriter keyboard, there is provided at the side of the keyboard and upon the same fulcrum that supports the lever 117, a lever 143. For operating said lever 143 manually, a key'144, attached to said lever 143, is provided.

The lever 143 is supportedfas shown in iFigure 3, Within the typewriter frame on a bushing 142 which serves as a nut for securing a stud 145 upon which the lever 117 is pivoted. Thus it will be seen from Figure 3 that levers 117 and 143 are mounted upon virtually the same fulcrum, but on opposite sides of the typewriter frame. An extension 151 from thev lever 143 is directed to the outer side of said typewriter frame, so that the key 144, located outside of said frame, may be thereby attached to said lever.

In order that operation of said key 144 shall be transmitted to the link 76 asan operating cycle initiating impulse, a train of simple mechanical connections is provided between said key 144 and said lin'k 76. Said.

train includes a bell-crank 146 that is pivoted upon the same fulcrum rod 124 upon -which the bell-crank 131 is mounted in the bracket 132. Connecting said bell-crank 146 to the lever 143 is a link 147. Upon the same fulcrum on which is pivoted the lever 134 there is pivoted a lever 148 for actuating the link 76, said lever 148 being connected at its upper end to4 said link 76 by means of a pinand-slot connection 149. A link 150, similar to the link 137, connects the lever 148 to the bell-crank 146. The train of parts beginning with the key 144 and ending with the cam-lever 72 is held in normal position by the pull of a spring 152, one end of which is conveniently applied to the link 150. The other end of said spring 152, like the spring 139, is attached to the'bracket 140. A stoppin 154 driven into the typewriter side frame may be provided to limit the downward stroke of the key 144, as shown in Figure 4.

The links 137 and 150 are offset, as'shown in Figure 2 on account of the offset positions of the parts which each link connects.

During the return movement of the carriages, operation of ,all the typewriter keys and key-levers is to be prevented, f-or reasons already set forth. Each of the key-levers 14 has the usual hook-shaped locking projection 155. Coacting with said hook-shaped projection when the keys are to be locked, is the usual key-lock rod 156, which is part of the regular Underwood key-lock mechanism. Said key-lock rod is supported at each end by an arm 157 and its intermediate portion is supported by an arm, not shown. The arms 157 rotate with a shaft 158, pivoted between the typewriter side frames. The usual spring .159 normally holds the key-lock rod in position, shown in Figure 1.

For causing the key-lock rod 156 to be in locking relationship with the key-levers 14 during 'the return of the carriages, there are provided means whereby said locking relationship is effected concurrent-ly with the displacement of the aforementioned train of linkage 104. To this end there is provided a link 160 which connects said train of linkage 104 to an arm 157, which with a paired arm supports the key-lock rod 156. It will be seen that as said train of linkage 104 is d-isplaced the key-lock rod 156 will move into locking relationship with the key-levers 14, as shown in Figure 6. In order that the keylock rod 156 may be actuated by the usual carriage controlled means (not shown) independently of the link 160, said link 160 is connected to the arm 157 by means of a pinand-slot connection 161.

As shown in Figure 1, a portion ofthe connecting linkage between the typewriter and the card perforator is below the platform 133 which supports the typewriter. -As a guard for the portion of the linkage which is below said platform there is provided a casing 162. Said casing may be formed, as shown, so as to be as close to the platform 133 as possible in order not to interfere with the knees of an operator. In certain other arrangements of the contacts which are contained in the casing 36 below the typewriter keyboard, the contacts are incorporated in a unit which 'is fastened below the platform 133. An outline of said unit would be indicated by the dotted line 163, Figure'l. Where such a unit is used the casing 162 should have an asbestos lining 164, so that said casing is protected from sparks or other hazards which may be incidental to the operation of the contacts and other electrical devices in said unit.

A card 10 is inserted intothe typewriting machine around the platen 11,- whereupon,

by means of keys 13, types 12 are operated to cause one line to be typed on the card. The depression of each key 13 in the typewriterkeyboard, besides swinging its corresponding type to print against the platen 11, simultaneously by means of an electric connection operates one of the series of Bowden wires 33 on the Powers machine, to swing plunger 31-26, which in turn 'sets up a pin 23, which will later on co-operatevwith the corresponding punch 18 to make a hole in card 10. The operation of the keys 13 also feeds the typewriter-carriage and the punch-selecting carriage in unison, as the carriages are connected through the racks 43 and 45.

After one line is typed on the card, and the corresponding pins 23 are set, the card is removed from the typewriting machine and slid to a position shown in Figure 5, so that feed-rolls 51, 52 of the punching mechanism may, when revolved, feed the card under the punches 18.

It will now be realized that thel card 10 *will rst be fed under the punches and punched, and then fed out into the container 56, prior tothe returning of the typewritercarriage and punch-selecting carriage, inas- 1 much as the return motion of the latter carriage restores the punches to their normal Acome into play, is so connected that, when operated, it will not actuate any of the typewriter-carriage-return mechanism, but the depression of said key 144 will merely close the clutch, being for this purpose caused to depress the link 147, which in turn will operate the bell-crank 146, moving the link 150 forwardly to swing the clutch-releasing arm 148 about its pivot, which will move the camlink 76 rearwardly and causethe clutch-controlling cam 72 to be swung away from the clutch-pin 68 and allow\ said clutch-pin to move forwardlyvto project into the path of the constantly revolving punch-operating disk 67, to have the card punched prior to the return ofthe carriages.

It will thus be understood that nothing happens to either the typewriting machine or the punching machine until one of said punches.` Then the revolving cam 59 swings the member 60 to raise and lower said cardplatform 21 and cause the card 10 to be punched, after which the card feeds out.

The initial movement of arm 69 -sets the bell-crank 118 for operating the tripper 119 of the typewriter-carriage-return mechanism. This setting is done by the projection 129 on said arm passing the end 130 of the lever 125 Nvhich allows said lever 125 to be swung by spring 139, to operate the train of linkages 136, 134, 137, 131, 138, and cause the bell-crank 117-118 to be moved to a position shown in Figure 4 in back of the typewritercarriage-return tripper 119. At this point, the bell-crank 118 remains until the powerdisk 67 has carried the clutch-pin 68and arm 69completely around, at which time the projection 129 engages the arm 130 of the bellcrank 125 and moves the train of links 136, 134, 137 131, 138 inthe opposite direction so as to cause the bell-crank 118 to engage the 'tripper 120-119 and set oif the carriage-return mechanism ofthe typewriting mlachine. This restores the carriage of the typewriter together with-the carriage of the punching mechanism, and the restoring of the punching carriage restores all the punches to their normal position. A new card can now be inserted into the typewriting machine and the operation repeated. It will be seen that in the carriage-return ing train, governed by key 144, there is connected the punch-operating mechanism, so that after typing a. line, the operator will not return the carriage without intervening operation of the punches by 'said mechanism included in said train.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
