Patented May 26, 193l UNITED STATES PATENT OFFICE COMPANY, LIMITED, OF TORONTO, CANADA, A. CORPORATION'OF ONTARIO CARBON CONTROLLER FOR TYPEWRITING MACHINES Application filed November 15, 1926; Serial No. 148,361. Renewed October 22, 1930.

This invention relates to writing machines, such as typewriting machines and, with respect to its more specific features, to control an actuation of the transfer sheets in conjunction with typewriter printing mechanism of the kind which is ada ted to travel, or shift over the record strips, t e record strips being in superposed relation for manifolding.

One of the objects of the invention is the provision of writing machine adapted for manifold-typing long relatively superposed, paper record strips; a machine which lends itself, in a practical and eflicient manner, to

all the operations and manipulations required to operate on such long superposed record strips and produce a number of similar typed copies, and in which the operations of altering the typed matter on any one or all the copies are facilitated and may be speedily and efiiciently accomplished.

An objectspecially lending itself to the foregoing object is the provision'of a'simple and practical device wherewith the actuation and positioning of the transfer sheets especially a large number of relatively superposed transfer sheetsis rendered easy and convenient, so that underlying record strips may be exposed for inspection and correction while the transfer sheets remain in their sequence of superposition relative to the record strips. j

Another object is the provision of a writing machine of the character referred-in which all of the superposed transfer sheets for transferring inscription from one record strip to another are caused to lie in relatively taut condition between and crosswise of the assured, largely without the attentionof the operator. u

Other objects of the invention will in, part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combinations of ele- EDWARD KIRBY BOTTLE, 0F ELMIRA, NEW YORK, ASSIGNOR TO AMERICAN SALES BOOK ments, and arrangements of parts, which will be exemplified in the construction hereinafter set forth and the scope of the application of which willbe indicated in the claims.

For a fuller understanding of the nature and obj ects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawings, in which: Fig. 1 is a side'elevation of a writing machine embodying the invention, certain parts being omitted for clearness of illustration.

Fig. 2 is aplan of Fig.1, the typing mechanism and certain other details 'being omitted. Fig. 3 is a plan View, similar to Fig. 2, both the typing mechanismand the carriage therefor being omitted, and some modification of parts belng illustrated.

' inclusive.

tween the parallel sidebars 2 of the frame of the machine, the frame including legs 3 suitable in number for supporting the platen at a convenient height for the operator.

, Opposite the advance end of the platen is a clamping jaw 4 which, by a suitable pedal 51, and operative connections therefrom to said clamping jaw, such as the link 52, and levers 53 and 54, and spring 55, may be caused to cooperate with the platen to grip and release the record strips at such point. The record strips, in superposed relation, advance to position over the platen where they may be operated upon by the printing mechanism of the machine. A large number of record strips in superposed relation may be employed. For the purpose of illustration, three record strips, 5, 6, and 7 are shown. In Fig. 3 these strips are shown broken away. These strips may come from any suitable source of supply, and each strip has a longitudinal series of printed forms and weakened lines between successive forms, the forms on one strip being adapted to register in superposed relation with those on the other, so that printing upon the uppermost strip will be transferred to the lower strip in the same relation in the printed forms. A part length of one of the printed strips on a reduced scale is shown in Fig. 8, the weakened lines being indicated at 56. To feed the record strips, the clamp 4 may be lifted by operation of the pedal, the superposed strips grasped by the operator and drawn across the platen so as to bring the next succeeding set of printed forms into inscribing position on the platen. Thereupon the clamp 4 will be permitted to resume its grip on the strips. This clamp will hold the stripstightly so that the previously inscribed sections of the strip may be torn off along the straight edge provided by the clamp or along the weakened lines, which latter are in registry when the forms are.

The numerals 8 and 9 indicate two trans fer sheets, the sheet 8 lying between the two uppermost record strips, and the sheet 9 lying between the two lower record strips. These transfer sheets are adapted to transfer printing impression from the topmost record strip to those below, and may be of usual transfer material as, for instance, the well-known carbon transfer sheets of paper. The nu.- merals 10 indicate a pair of parallel guide,

guide-rods or bars,rotatably supported along-- side the path of the record strips. These guide-bars are similar to each other and are similarly supported on the frame of the machine, so that description of one will suflice for both. The numerals 12 and 13 indicate brackets bolted to the outside of the frame members 2 and providing bearings in which the guide-bars 10 are journaled. The bracket 12 has apivoted jaw 14 which is adapted to cooperate with an annular groove in the rod 10 to hold said rod from longitudinal movement. A spring 15 is utilized to retain jaw 14 in cooperative relation to the rod 10. The bracket 13 carries a split block 16, each section of which is suitably shaped to provide a bearing surface 17 for the cylindrical end 18 of the guide-rod 10. A thumb screw 19 serves to regulate the grip of the bearing surfaces on the guide-rod, so that the resistance to rotation of the guide-rod may be regulated, or the.guide-'rod held from rotation, as desired. The guide-rod has a knurled head to facilitate its convenient rotation. The guide-bars 10 are thus removably connected to the frame of the machine. It will be understood that the above description applies equally to Figs. 1 to 5, inclusive.

Longitudinally slidable on the guide-rods 10, so as to be reciprocally shiftable lengthwise relative to the record strips, are the transfer sheet holders 20 which, in the embodiment of Figs. 3, 4, and 5, include a pair of cylindrical cores made of wood, one core for each rod, the length of each core being equal to the width of a transfer sheet. The cores are indicated in dotted lines in Fig. 3. Each of the transfer sheets is coiled around and held on the two cores and is adapted to unwind from one core and extend therefrom into transfer relation to the record strips, crosswise of the direction of advance of such strips, as clearly illustrated in Fig. 5. In the embodiment illustrated in Figs. 3, 4, or 5, rotation of either of one of the guide-rods is intended to effect rotation of the core 20 thereon and consequent feed movement of the transfer strips from the other core, for the purpose of bringing fresh transfer surface to the printing point. The rods 10 may be rotated in either direction. The axial-bearing opening 57 through the cores is made angular in shape, and the cross section of the bars 10 is similarly angular, so that rotation of either of said bars will effect rotation of its core 20, the cores nevertheless being adapted to be reciprocally shifted longitudinally of the guide-bars, when desired.

- For the purpose of shifting the cores 20, a manually operable, reciprocal, shift-frame may be provided, and may include two shiftable yokes of similar construction, each core being preferably detachable fromf'its yoke. Each yoke is adapted to act as a core-shifter and comprises a neck 21 and two arms 22 and 23, between which arms the core 20 is interposed. The arm 23 of the shiftable yoke comprises two bearing jaws 24 and 25 (Fig. 5), the jaw 24 being pivoted at 26 to the jaw 25. The bearing provided by the cooperative jaws 24 and 25 is sufliciently large to permit rotation of the angular guide-bar relative to the yoke within the bearing and supports the yoke as it is shifted or slid longitudinally in either of opposite directions along said guide-bar. For holding the bearin jaws 24 and 25 in closed position, a latch 2 carried by arm 23 is adapted to engage a tooth 28- 22 and 23 to be varied so as to adjust the width of the yoke. As illustrated, one end 31 of rod 21 is of angular cross-section so .as to enter and fit a counter-part angular aperture 32, in the arm 23. Threads on the end 31 receive the nuts 33 for holding the rod 21 in adjusted position on arm 23.

Washers 34 and 35 are interposed between the ends of cores 20 and the yoke arms 22 and 23. These washers are shiftable on 'the guide-rods 10, which pass through angular bearings opening therein, and the washers also serve as gauges for the opposite edges of the transfer sheets where wound on the cores. It willv be seen that, when the yokes are shifted longitudinally on the guide-rods, positive shift of the cores therewith is effected, the washers protecting the edges of' the transfer sheets from injury by direct contact with the yoke arms.

In order that the two transfer sheet holders 20 may be shifted in a uniform manner, they are connected for shifting together. To effect this the shiftable yokes hereinbefore described are joined across the machine beneaththe platen 1, by a strong and rigid shifter bar 36, which is a part of the shift frame. As illustrated, the bar 36 is integral with the two yoke arms 23, and is bent at 37 to underlie the side frame members 2 and may have the upturned part 38, better to escape the knees of the operator. The yoke arms 23 have elongated bearings as at 40 proyided by the jaws 24 and 25, which closely fit around the corners of the angular guiderods 10, and relative to which the guiderods 10 may rotate. By this construction, simultaneous shift of both yokes is effected by manually shifting either, or by shifting the shifter bar 36, with consequent simultaneous shift of both holders, orcores 20. It will be seen that the points of attachment of the transfer sheets to the shift frame, through the cores and yokes, are respectively adjacent each of opposite sides of the record strips, so as to readily permit the transfer sheets to enter between the record strips.

In order to minimize chance of the transfer sheets being shifted into position to be gri ped by the clamp 4, the extent of their shi t toward the advance end of the platen may be limited so that the ultimate extent of shift will not be sufficient to carry the transfer sheets into gripping relation with said clamp. To this end the rods 10 may each be provided with yoke stops 39 longitudinally adjustable on said rods, and against which the bearings 40 of the yoke arms 23 are adapted to abut, to arrest the transfer sheets short of the clamp 4'.

In the form illustrated in Fig. 3, the trans- .fer sheets are wound upon cores 20, of which there is one at each side of the path of the record strips. A plurality of the transfer sheets, in superposed relation to each other, are rolled into a coil at one end, on one of the cores, one end of the assemblage being held on the core by suitable spring clips. The free ends of the sheets are then drawn across the platen and attached to thecore 20 at the other side, so that, when the latter core is rotated by\ s rotating its guide rod 10, the transfer sheets will be drawn from one core and wound up on the other, as will be readily understood. It

will be perceived that the transfer sheets lie between superposed record strips, so that the path of one of the sheets from core to core is longer than that of the other. In the embodiment' illustrated, the path of the topmost transfer sheet is the longer, and this sheet acts as a driver and is tautened from core to core by'the drawing operation. The underlyingtransfer sheet, however, has a shorter path,

and the drawing operation results in the production of slack in the underlying transfer sheet, which slack may result in buckling, or loose condition thereof between. the record strips, so as to interfere with efficient manifold inscription thereby. Suitable provision is made for tautenin the underlying transfer sheet where it lies lmtween the record strips and, preferably, the means for doingsois made shiftable with the transfer sheets. In the embodiment illustrated, referring to Fig. 11, the underlying transfer sheet 9, and all the other underlying tranfser sheets, if more than two are employed, are pressed by a'weighted roller 60, which is adapted freely to gravitate in guideways 61 in the upstanding arms 62 of a U shaped frame, the cross piece of which is indicated at 63, this U shaped .frame being removably fixed to the side face of the shifter frame 36, between one of the cores 20 and the adjacent record strips. The weighted rollers 60 are independent of each other and rest freely upon the underlying transfer sheets and freely gravitate downwardly in the guide ways61. These rollers 60 may be introduced at the top of the guideways 61, or they may be introduced laterally of the transfer sheets upon removal of the keeper plates 64, which latter are'removably attached to the outside take-up device may be duplicated on the 0pposite side of the machine, if desired. As the underlying transfer sheets are delivered from the coil, the rollers 60 take up the slack so that such sheets lie in fiat and fairly taut condition between the record strips.

Instead of rotating one of the cores 20 to draw the superposed transfer sheets across the platen, provision may be made whereby they may be conveniently drawn by hand from one of the coils. To this end the wing nut 19 may be screwed up tightly to prevent rotation of one of the guide rods 10, as, for

.instance, the guide rod illustrated at the transfer material over the platen.

upper part of Fig. 2. Thereupon, a rod or bar 65 may be utilized simultaneously to grip all the transfer sheets against the surface of the core. In this case, however, 1t is preferred to flatten the surface of the core as illustrated at 66 in Fig. 10, so that the bar 65 may effectively grip the transfer sheets throughout their width. The bar 65 may enter slots 67 and 68 in the washer 35 and arm 23, respectively, so as to be removably held in position. A tight fitting of the bar 65 in the slots will be sufficient to cause the bar to firmly grip the transfer sheets and hold them in place. By raising the bar 65, grip on the transfer sheets will be relieved. Thereupon the transfer sheets may be grasped by the hand and drawn from the coil on the opposite side so as to bring fresh It will be noted, also, that each transfer sheet may be separately manipulated and tensioned across the platen so as to avoid slack. The bar 65' may have a straight edge 68 adjacent the transfer sheets, so as to provide a tearingbar, against which the transfer sheets may be readily torn, and the used portions thus removed. It will be noted that the bar 65, like the core 20, is shift-able with the transfer sheets and with'the shift frame 36.

The typewriting mechanism is indicatedgenerally by the numeral 70. This consists of a typewriter which is shiftable over the platen 1, both in line spacing and letter spac ing directions. The illustration herein of the typewriter is largely diagrammatic, it being sufficient to say that it is a regularly operating typewriting machine shiftable as stated, and it may be similar to the shiftable printing mechanismcommonly employed in typewriting machines having a large rela tively stationary, flatplaten, such as the platen 1 referred to herein. An example of such a tvpewriting machine is found in the Elliott- Fisher billing machine, which is commonly used. The shiftable typewriting machine has the usual inking ribbon, which shifts with the typewriting machine both in line spacing and in letter spacing directions, the.

type of such machine striking against the ribbon, which ribbon is thus pressed against the uppermost record strip and gives the inscription on the top record strip. It will thus be seen that the typewriter ribbon acts as a transfer sheet and that it is independent of the other transfer sheets, 8 and 9. In Fig. 1 the inking ribbon is diagrammatically illustrated at 71 and a striking type at 72, it being understood that suitable guides on the typewriting machine support the ribbon in position opposite the rinting point, where struck by the type. upporting the printing mechanism, and practically forming a part of the frame thereof, is a carriage which is reciprocally shiftable over the relatively superposed record strips. In its main construction the carriage is of the form commonly employed in the Elliott-Fisher billing machine, and includes the front and rear parallel bars 75 and 76 oined by the arallel longitudinally extending bars 77 an 78, to form a rigid rectangular frame through the opening in which the record strips are exposed, and may be reached by the printing mechanism of the typewriter. On the front bar 75 of the carriage are rollers 79, which rest upon the side frames 2 and support the carriage at the front, the side frames 2 acting as tracks. At the rear are the large rollers 80 and 81 j-ournaled on a shaft 82 supported in brackets extending rearwardly of the carriage. At the outer sides of the rollers 80 and 81 are the pinions 83 and 84 fixed to the shaft 82, and engaging racks 85 and 86, fastened to the adjacent side frames 2. Fixed to rotate with the shaft 82 is the finely toothed ratchet wheel 87. The numeral 88 indicates a pawl having severalz teeth adapted to cooperate to engage the teeth of the ratchet wheel and rotate the latter. The pawl 88 is pivoted to an intermediate pawl arm 89 oscillatably mounted concentrically with the shaft 82. The arm 89 is stressed to rearward position by a spring 90, so that the pawl 88 lies against a stop pin 91. By rotating the pawl arm 89 to the left, Fig. 1, the pawl 88 will cooperate to rotate the ratchet wheel 87 and thereby rotate the pinions 83 and 84, so as to shift the carriage to the left,relative to the platen, the direction of shift in the embodiment illustrated being for line spacing. For actuating the pawl arm 89 to effect shifting, it 'is' operatively coupled with an oscillatory rod 92 mounted on the side of the carriage and extending to the front, where it is provided with a handle 93 for manually actuating the same. Fixed to rod 92 is a cam arm 120 which lifts a gravitatively movable plunger 121 to in turn contact with and move a projection 122 of an arm 123 journaled on shaft 82. The retracting spring is connected to arm 123, as shown in Fig. 1. Arm 123 has a pin 124 engaging a slot in pawl 88. By rotating the handle 93 in one direction the carriage is caused .to shift until the arm 123 is arrested by the stop 94:. Upon releasing the handle 93, the arms 89 and 123 and pawl 88 are retracted, ready for again rotating the ratchet wheel 87 in line spacing direction. It will be observed, however, that the carriage frame may be grasped and moved 5 .back and forth at will in line spacing direction, when the pawl 88 is out of engagement with the ratchet wheel. The ratchet wheel and its actuating members, including the handle 93, are for the purpose of progressively advancing the carriage in line spacing direction, line by line, as it were. The detailshifting mechanism for the carriage just described is similar to that employed in the Elliott- Fisher billing machine to which reference has been made. I On the carriage rests the typewriting machine 70, being supported at the front by the rollers 94 resting on the bar 75, and being supported at the rear by the rollers 95 restzq ing on the bar 76, the typewriting machine being held against movement in line spacing direction relative to the carriage, but being reciprocally shiftable on the carriage in letter spacing direction, in the present embodi ment, and as exhibited in the Elliott-Fisher billing machine aforesaid.

Depending from the bar 7 6, or lateral extensions thereof, are devices which are adapted to be moved into'and out of position to causeshift movement of the transfer sheets 8 and 9 in li'ne-spacin direction, with the carriage. In the em odiment illustrated this means .,consists of a dog, or dogs, 100

(Fig. 1) 'pivoted to brackets 101, which brackets are removably attached at opposite ends of the bar 76. When in lowered position, as illustrated in Fig. 1, the dogs 100 are adapted to contact with the yoke arms 22 of the shiftable frame, and thereby shift said frame and the transfer sheets carried thereby, in line-spacing direction. In the embodiment illustrated in Figs. 1 to .5, inclusive, shift of the carriage toward the left, Figs. 1 and 2, causes shift of the shift frame by the dogscoming into contact with the arms 22 and thereafter pressing the shift frame to the left, the carriage being freely shiftable to the right independently of the shift frame. When desired, however, the arms 22 may be provided with a retainer arm 102, Fig. 12, pivoted to the arm 22 and movable into and out of position opposite the dog 100, so that as the carriage shifts to the right, Fig. 2, the shift frame will move therewith.

, To arrange the machine for operation, the

printing mechanism 7 Owill be shifted rear -wardly, and the several record strips drawn from their supply" into position over the platen 1, the lowermost record strip lying on the platen. Thereupon, the other record stripswill be thrown back and the lowermost transfer sheet laid in position on the lowermost record strip. Then the other record strips are replaced in succession over the pIaced transfer sheet, and interleaved with the other transfer sheets, as will beunder stood. Then the free ends of the transfer sheets are attached to the core at the opposite side'of the machine, beingdrawn as taut and smooth as desired. The advance ends of the record strips are then laid under the clamp jaw 4. The machine is then ready for typing the record strips. The printing mechanism may be shifted longitudinally of the platen by shifting the carriage, and crosswise of the platen by shifting the printing mechanism on'and relative'to the carriage. It will be understood that the crosswise shifting of the printing mechanism may be accomplished either by hand or bythe letter spacing key of the typewriter, as usual in machines of the type herein referred to, and exemplified in the Elliott-Fisher billing ma chine.

Printing on the topmost record strip will be transferred to the underlying record strips by the interposed transfer sheets. Typing having been completed, the pedal 51 may be actuated to relieve the clamp 4 from grip on the record strips and. the latter may be grasped by the operator and drawn longitudinally along the platen so as to bring succeeding printed forms into positionon the platen, all without disturbin the transfer sheets. However, should it be desired to alteror correct the typed inscription at any point, the printing mechanism may be shifted rearwardly a sufficient amount, and the transfer sheets may'also be shifted to position uncovering transferred impression on the underlying record strips. Then, by freeing the record strips from the front clamp 4, they may be lifted and thrown back at will, so as to expose thetransferred impression on any one of them, and correction may conveniently be made as desired. It will be noted that the may be restored to superposition, and this superposition will be the same as before, with v the several transferred inscriptions in superposed registry with each other. Thereupon, theshlft frame may be actuated to return the a transfer sheets to position required formanifolding impression, as before. It will. be seen, therefore, that corrections, alterations,

' additions, and the like, may beapplied to the underlying record strips, while maintaining superposed interleaved arrangement of the transfer sheets ateither side of .the platen.

When a transfer sheet is sufiic'iently wide to .transfer sheets, and without detaching-the v cover the usual writing spacefit maybe un- '22, before the printing point has reached the edge 105 of said transfer sheets, and thereafter said transfer sheets will be shifted with the printing mechanism as the latter shifts in line spacing direction. When desired, the dogs 100 may be readily turned upwardly and held out of position for effecting shift of the underlying transfer sheets by the carria e. Inasmuch as the edges 105 of the trans er sheets shift toward position underlying clamping jaw 4, it is-intended that the bearings 40 shall contact with the stops 39 before this happens. This arrest of the shifting of the transfer sheets will prevent clamping of the transfer sheets by the clamp 4 and avoid tearing of such sheets when the shift frame is moved in the opposite direction. It will be noted that when the transfer sheets 8 and 9 and the printing mechanism are in relative position to manifold printing impression, the ink ribbon transfer sheet 71 is in superposed relation to the transfer sheets 8 and 9, which underlie record strips, and it will be further noted that, notwithstanding that the ink ribbon transfer sheet is independent of the other i transfer sheets, and at times is shifted independently of the latter, nevertheless, provision is hereby made for maintaining superposed relation between the ink ribbon transfer sheet and the other transfer sheets during shift of the ink ribbon transfer sheet in line spacing direction.

By the provision of the slack take-u means, the underlying transfer sheets, thou uncoiling from one core and coilin on t e other, are nevertheless kept taut an smooth between the record strips. As explained in connection with the flat-faced core illustrated in Figs. 2 and 10, the underlying transfer sheets may be drawn" from one core by hand so that all shall lie in smooth, taut condition between the record strips, the bar affording means for tearing 011' used portions of the transfer sheet's. Inasmuch as the cores 20 are separate from the washers 34 and 35, and

inasmuch as the yokes are adjustable in width through the instrumentality of the nuts 33, it will be seen that the machine is adapted to accommodate'transfer sheets of several difierent widths.

It will be noted that in each modification the transfer sheets 8 and 9 are so connected to the shift frame that it always remains in flat manifolding condition between its points of attachment to the frame, whether shifted in one direction or the other. The cores 20 serve to brace the transfer sheets widthwise and take the pressure of shifting. Also the tearing bar 65 coacts with the adjacent core to brace the transfer sheets widthwise. Thus there need be practically no crumpling of the transfer sheets 8 and 9 during their shift movements.

Since certain changes may be made in the above construction, and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as-illustrative and not in a limiting sense.
