Serial No. 154,667.

This invention relates to combined typewriting and card-perforating machines, and particularly to means for mechanically connecting the carriages of the typewriter and card-perforator mechanisms of such machines.

The main object of the invention is to provide and make possible the provision of simple carriage-connecting means. In my application No, 48,723, filed August 7, 1925 (now Patent No. 1,683,979, dated September 11, 1928), areset forth the advantages resulting from mechanically-connected typewriter and perforator. carriages, said advantages attending the positive synchronism attained in the movements of both carriages,

and the use of single escapement, tahulatin'g,

back-spacing and power-driven carriage-return mechanisms to serve both carriages. In said application there is shown a Powers keypunch coupled to an Underwood typewriter, for the purpose of producing perforated record-cards having typed headings which read on the perforations in the card. These cards are, as is well known, used in various processes of mechanical accounting. The owers key-punch is of the type shown in the U S. Patent No. 1,305,557, to W. Lasker, hated June 3, 1919, and is hereinafter called the card-perforator or perfo rator. I

In said application, the card with its upper margin against the platen, moves with the typewriter 'carria e in the usual letter-feeding direction as tie heading is being typed thereon. While the typewriter-keys are being operated to print said heading, punches corresponding to the characters typed are automatically rendered eiiective in the perforator for perforating the card after the-typing of the heading is finished. The perforator is behind the typewriter, and has a bank of unches, which, viewed endwise, are arranged in columns corresponding to the well-known arrangement of the hole-spaces in the card. The punches are renderedeffective by setting corresponding index-pins which are aligned endwise of the punches. As a character is typed in a hole-space col umn in the card one or more punches, depending upon the character typed, are rendered effective in the corresponding punch-column of the perforator, the typewriter-carriage er.- caping in the usual manner to the next printing position after the character is printed. A column of index-pin-setting 'lungers is mounted in the usual carriage, w 'ch forms part of the card-perforator, and serves to register said column of pin-setting plu'ngers with successive columns of index-pins. In order to do this, the card-perforator-carriage must move simultaneouslywith the typewriter-carriage, and is shown in said application, mechanically connected to the typewriter carriage by means of a rack on each carriage, and a pinion. intermediate'said racks. In the process of setting the index-pins, the card-perforator-carri-age moves from left to right, or in a direction opposite to the direction of movement of the typewriter-can riage, which is from right to left,-and it is to move the carriages in opposite directions that therack-and-pinion connection is resorted to. The cards are thus inserted in the perforator after the heading'has been typed, and the perforator is operated in the usual manner to effect the punching of holes in the t ped card by the punches which were indexed while the heading was bein typed. According to the present specific orm of the invention, it is contrived to dispense with the carriage-connecting train of gears, and

the typewriter and perforator carria es are connected by means of a simple tiear or link. The typed cards are inverted and inserted in the perforator face down, in such a manner that the columns of punches may index from right to left, or in the same direction that the typewriter-carriage moves in its letter-feeding operation. The typewriter and card-perforator are so disposed relatively to one another that their carriages mav be thus directly connected.

In this form of the invention are presented the advantages of using simple tie-bar or link connections between the two carriages that are economically manufactured. They are easily adjusted, because the guides on 4 which the respective carriages move need'not wei ht to the moving carriages; and a single tiear, which usually sufiices to connect the carriages, may be disposed at one side of the line of insertion of the card into the perforator, and thereby facilitate said insertion.

Following the movement of the card-perforator-carriage from right to left to set the index-pins, and after the perforation of the card for which the index-pins have been set, has been effected, said perforator-carriage is returned with the typewriter-carriage. The same means as described in my aforesaid application may be used to automatically restore the set index-pins during the return movement of the perforator-earriage. It is necessary, in this form of the invention, on account of the inverted movements of the perforat-or-carriage, to reverse the arrangement of said pin-restoring means, as will hereinafter appear.

Other features and advantages will hereinafter appear. I I

In the accompanying drawin s,

Figure 1 is a cross section 0 a combined typewriter and eard-perforator, and shows the carriages of said typewriterand cardperforator connected according to the present inventnion.

Figure 2 is a fragmentary front elevational view of the card-perforator-carriage, and shows the cross-bar connecting said carriage to the rear cross-member of the typewritercarria e. This view also illustrates the manner o reversing the pin-restoring means in accordance with the inverted movements of the perforator-carriage.

Fi ire 3 is a top plan view of the combinef typewriter and card-perforator, showing partlcularl the relative disposition of the carriages o the typewriter and card-perforator. Y

Figure 4 is a detail view, showing how a perforator-carriage guide-roll stud may be made to include a pin, which one end of a carriage-connecting tie-bar may engage.

Many details of the combined typewriting and card-perforating machine have been omitted in the drawings for the sake of clearness. There have been shown only such details, aside from the invention itself, as will make the operation of the invention and its relation to the machine clear. The illustrations show only one form of combined typewriting and card-perforating machine in which the invention may be embodied. The machine shown is used for first typing a heading on a record-card, and then punching holes corresponding to the heading after said heading has been typed.

A card 26 is placed around a platen 10 and positioned by means of a card-guide 11, which may be of the type shown in my previously-mentioned co-pending application. Said platen 10 is mounted on an axle 12, journaled in the usual platen-frame 13,

that its type 25 prints on the card. By means of the card-guide 11 the card is so positioned that the captions or headings are printed along the upper margin of the card. The usual heel of the type-bar engages a universal bar 27, and moves it rearwardly in the usual manner, to operate an escapement dogrocker 28 fulcrumed at 29. Said dog-rocker has the usual fixed dog 30 and stepping dog 31, which co-operate with the usual escapement-wheel 32, to cause the carriage to move in letter-feeding steps impelled by the usual spring-motor 33 connected to the typewritercarriage by a draw-band 34. The pitch of the e'scapement-wheel teeth is such that the typewriter-carriage moves in steps that equal the spacing of the hole-space columns of the card. The escapement-wheel is connected in the usual way to the pinion 61 which meshes with the usual rack 62 on the carriage.

The usual record-card has five hundred and forty hole-spaces arranged in forty-five denominational columns of twelvehole-spaces each. In the perforator there is accordingly a set of five hundred and forty punches also arranged in forty-five denominational columns of twelve punches each. Figure 1 shows a cross-section of the perforator through the set of punches represented by one of the columns of punches 35. The upper ends of the punches are guided in a fixed plate 36 and the lower ends are guided in a plate 37. Below the punches is a die-plate 38 having a die-hole for each punch and co-operating with the punches to perforate a card. The lower punch-guiding plate 37 and the die-plate 38 are separated by a gap 39 in which a card, when it is to be punched, is inserted. The lower punch-guiding plate 37 and the die-plate 38 are members of a frame 40 which is movable upwardly to effect perforation of a card. It is obvious that such perforation will be effected if the. punches are prevented from moving upwardly when the frame, with the card in punching position therein, is moved upwardly. Any punch may be selected to perforate the card by setting means against it which prevent it from moving upwardly. For thus selecting punches which are to perforate a card, there is provided a bank or set of settable index-pins 4:1,

in columns. Each pin is depressible and may be latched in its depressed position by means of the usual spring-pressed latch-bar 42, there being one of said latch-bars for each column of index-pins. In Figure 1 th e first pin is shown depressed to prevent the upward movement of the first pun ch, thereby rehdering said punch effective to perforate the card when said card is moved upwardly with the frame 40.

Key-controlled means-are used to set the index-pins 41 in one column at a time and include a column of pin-settin plungers 44. For up and down movement t e lower portion of each plunger 44 is guided in a plate 45 and the upper end of said plunger is pivotally connected to the horizontal arm of a bell-crank 46 whereby said plunger is actuated in the usual manner to be described. To enable the column of pin-setting plunger-s 44 to register with successive columns of index.-

pins 41 said column of plungers is so mounted that it may traverse the columns of indexpins. For this purpose the plungers 44, the plunger-guiding plate 45, and the bell-cranks 46 are mounted in a perforator-carriage generally indicated by the number 47. Said perforator-carriage is guided upon rails 48 and has rolls 49 and 50 which engage respectively the upper and lower surfaces of said rails.

The plunger-actuating bell-cranks 46, of which there is one for every pin-setting plunger, are mounted upon a common fulcrum-rod 51 and, in the joint operation of the typewriter and perforator, are selectively controlled by operation of the typewriterkeys 18 and 19. To enable said typewriterkeys to control the bell-cranks 46 there are used the usual electromagnetic means or op erating trains which are fully set forth in my previously-mentioned co-pending application. l/Vhere holes in the card are used to represent alphabetical as well as numerical characters, more than one hole is in some cases needed to represent la character. -The code, according to iw hich ,the characters are represented by holes, 1; such that the number of holes for one character is never more than two. Operation of any typewritenkey there fore must set index-pins for one or two punches in a column. The operating trains or electromagnetic means whereby this is accomplished include a number of electromagnetic solenoids having plungers for actuating the bell-cranks 46. [Said solenoids and plungers (not shown in detail) are in 9. casing 54 forming part of the perforator. To-

transmit the movement of the solenoidplungers to the bell-cranks 46, there is the usual flexible push wire 55 encased in the usual flexible sheath 56. The flexibility of the push wires and their sheaths enables the perforator-carriage, to which one end of each ush wire is connected, to move freely upon its rails. In a casing 57 below the typewriterforator, and said connecting wires are gath- Y ered in the usual cable 60, see Figure 3. I When a card is to be inserted in the erforator for punching, it ma be presente with its'top edge against the rst pair of a series offeed rolls 63 which carry the card into punching position in the gap 39. The feed rolls 63 are geared in the usual manner to a main shaft 64 of the perforator-mechanism. Said main shaft is normally disconnected from the usual driving means (not shown) and may be connected to said driving means by the usual clutch-mechanism (not shown). Said clutch-mechanism, by the usual electromechanical means, may be tripped by the usual trip key 65 on the'typewriter, said trip key being depressed when the card is presented to the feed rolls 63. The clutch-mech anism is so devised that it operates the main shaft to the extent of one revolution during which the main shaft drives the feed rolls 63 to first carry the card into punching position and raises and lowers the card-frame 40 to effect punching of the card. The punching position of the card in the ga 39 is determined by the usual stop 66. it the end of the revolution of the main shaft 64 the card is still in position in the gap 39 and is ejected from said position in a succeeding operating cycle of the main shaft during which a new card may be fed into punching position. While the punched card is being ejected from the ga 39 by the feed rolls 63, the stop 66 is cause to be withdrawn long enoug to permit such ejection. is deposited in the usual rece tacle. 67.

For enabling rotation of t e main perforator-shaft 64 to raise and lower the cardframe 40, there is on said shaft the usual grooved face-cam 68 whereby the usual frame 69 is rocked about a fulcrum 70 at each end of said frame. An arm 58 at each end of said frame 69 is connected to a corresponding end of the card-frame 40 by means of a block and-slide connection 71. The contour'of the cam 68 is such that the card-frame 40 is raised and lowered after the card has been ca'firied into punching position by the feed r0 s 63. i

The ejected card I As the characters for the -heading of a card are being typed, the carriage with the I sert' 26 ing position in the perforator,

so that a simple connecting bar 73 may serve to connect said carriages moving the perforator-carriage in the same direction as the t pewriter-carriage,

. to 1e t, the index-pins of the perforator will be set in successive columns beginning at the right. It is accordinglynecessary, when in- (the card in. he perforator, to turn over l3"tl1e= a'td after it is removed from the typewntemarm e, but ,without inverting its top edge. It is 0 vious that in thus turning the card the first hole-space column of the card will register with the first column of punches from-the right.

The typewriter and card-perforator are so disposed that when the typewriter-carriage is at the end of its letter-feeding travel t e card therein will be in line with its punchas shown in Figure 3. The typewriter 18 supported on the usual platform= (not shown which.,extends from the main frame 72 of the perforator. To guide the card in inserting it into 80 the typewriter there may be provided upon the typewriter-carriage the usual table surfaces 75 and 76, the latter surface 76 overlapping a table surface 77 which forms part of the perforator.

86 surface 77 there may be provided lateral guides 78 for guiding the card as it is presented to'the feed rolls.

In connecting the typewriter and perforator carriages it is preferable to use onl 0 one tie-bar 73, which,properly proportione should be sufficient to connect said carriages. A single tie-bar connecting the carriages may be disposed at the ends of the carriages as best shown in Figure 3. A single tie-bar thus disposed does not interfere with moving the card from the typewriter to the perforator. It may be desirable under some circumstances, however, to use a tie-bar projecting from each end of the typewriter-carriage.

There is accordingly shown in Figure 3, in

broken outline, another tie-bar 74 the provision of which is optional.

When a card has had a heading typed thereon and has been inserted in the typei 56 writer and punched according to the typed heading, the typewriter-carriage and perforator-carriage connected to it are returned to the original starting position. Said carriages may be returned either by hand or 10 there may be provided the usualpower-driven carriage-returning means, shown in my aforesaid co-pending application.

During the return of the carriages, the index-pins 41, which were previously set, may be restored so that all index-pins are in their that is, from right On the perforator table normal positions before beginning the typing of a new card. Included in the usual means for effecting the restoration of the indexpins 41 there is an'array of levers 80 extending along the ends of the latch-bars 42. Said levers 80 are so proportioned and positioned that, when they are overridden by roll 81 mounted on the perforator-carriage, they are turned aside. As the levers 80 are thus turned aside they in turn push the latch-bars 42 endwise and thus release all index-pins 41 which may be held down by said latchbars, each index-pin 41 being restored by its spring 82. Durin the pin-setting travel of the perforator-carrlage 47, the pin-restoringroll 81 is in such position as to be clear of the levers 80. For guiding and moving the index-pin roll 81 into andout of effective position it is mounted upon the usual lever 83 which is pivoted on a member 84 depending from the perforator-carriage. The index-pin-restoring roll 81 is automatically moved into effective position as the carriages escape after the last character of the cardheading has been printed. For causing the indegt-pin-restoring roll to be moved into efiectiv'e position it is connected to arm 85 which encounters a stop 86 and is rotatably displaced by said stop as the carriages take their last step. In'this, displaced position the arm 85, connected to the roll-supportin lever 83 by means of a link 87, is caught and held by a spring-pressed latch 88. Said latch may be pivotally mounted upon a member 89 secured to the face of a boss 90 projecting upwardly from the perforator-carriage frame 91. With the indeX-pin-restoring roll in effective position all the index-pins which were previously set are restored during the return movement of the carriages. As the carriages reach the end of their return movement, which may be determined by means of the usual typewriter-carriage stop 92, the latch 88 is withdrawn to release the arm 83 so that the index pin-rcstoring roll 81 may reassume its nornially-inefiective position. The restoration of the roll 81 is effected by means of a spring 93 which pulls upon the arm 85. ,The withdrawal of the latch is effectcd as an extension 94: of said latch encounters a stop 95 and is displaced thereby as the carriages reach the end of their return movement.

The means described for restoring the index-pins 4:1 may be substantially the same as shown in my aforesaid co-pcnding application and differ from the heretofore used means in that the latch 88 and the positions of the stops 86 and 95 are reversed to accommodate the reversed letter-feeding -movement of the perforator-carriage. The lower end ofthe link87 is connected as shown in Figure 2, instead of to the arm 7 9 of the pinrestoring roll-lever 83. To clear the lower perforatorcarriage roll 50 said lower end of 96 of the pin-setting plunger 44 extends, has

also been reversed. Said car has attached to it the usual spring 97 which draws the pin-setting plunger 44; upwardly, and, by means ofthe reversed car 96, keeps the advancing edge of said plunger against the proper side of its slot 98 in the plunger-guiding plate 45. Said slot 98 is elongated in the usual manner to permit the lower end of the plunger to trail if the perforatoncarriage 47 moves ahead before the plunger reaches the end'of its upward movement.

As shown in Figure 3, one end of the tiebar connecting the carriages may be secured to the rear cross-member 99 of the typewriter-carriage by screws 100. From said rear cross-member 99 the tie-bar projects upwardly and rearwardly to engage a pin 101 which may be part of one of the studs upon which the forward carriage-rolls49aremounted (see Figure 4). In order to compensate for any deviations from parallelism of the typewriter and perforator carriage rails, the tie-bar 73 may engage said pin 101 by means of an elongated slot 102, thus providing connection between said tie-bar and the perforator-carriage' that adjusts itself to said deviations without bringing the carriages out of step. As shown in Figure 3, the portion of the perforator-carriage frame 91, from which projects the pin 101, may be extended to meet an extension 103 of the tie-bar 73, the length of said extension 103 depending on how far said portion of the frame 91 extends.

As already mentioned, the invention is applied to a combined typewriting and cardperforating machine arranged for the particular purpose of writing headings on record-cards and punching said cards. The invention may be applied to other combinations of a typewriter and card-perforator, as for example where the typewriter is used to write on accounting sheets and at the same time set the p'eriorator for producing record-cards corresponding to what is written on the accounting sheets' In this case it is obvious that the perforator need not be placed behind the typewriter; it may, for example, be placed alongside the typewriter in such a way that the carriages may be connected in tandem arrangement, and a single tie-bar or link would also serve to connect said carriages. All such arrangements in which 'a simple link or its equivalent is used to connect the carriages are within the scope of d the invention.

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