OF SYRACUSE, NEW YORK, A CORPORATION 0F -NEIN TYPE-WRITING' MACHINE.

To all whom it may concern:

Be it known that I, HARRY I. SEDDON, citi'- zen of the United States, and resident of Syracuse, in the countyof Onondaga and 'State of New York, have invented certain rotary material-carrying device which operates automatically to rewind the material unwound during printing operations.

Another object 1s to provide an improved chute or guide-way and. one which properly vao copera'tes with a pivotally mounted platen in any of the positions to which said platen may be swung.

Another` object is to arrange and operate said chute so that it may be employed with a roll holder carrying a roll of material such as carbon paper to guide the material from` the roll to the platen, which material passes through said chute, and also to guide a work sheet or paper to be written upon. The device'is shown in` the present instance in connection with a folded work sheet. the chute being included between the folds of the work sheet.

Another object is to provide in combination'with a roll holder, an improved construction of cutting-blade adapted to sever the paper from the roller.

Various other objects will appear in the course of the following specification.

To the above and other ends the invention consists of the features-of construction, combinations of devices and arrangements of parts hereinafter fully described and particularlypointed out in the claims.

.In carrying out my invention in the Yform shown in the'prese'ntcase, I arrange a detachable framebr support on the carriage of the typewriting machine and pivotally mount at the upper end of said framea casing having a hinged cover within Awhich is detachably journaled a rotary material-carrying device or roll holder, saidroll holder carrvinga roll ofcarbon paper.A A chute or guide-way Specification of Letters Patent. Patented Jan. 11, 1910a Application led June 13,

extends downwardly from the casing and is pivotally connected at its lower end portion with the platen frame. T he carbon paper is guided downwardly from the roll holder through the chute and its free'end passes between the platen and the usual' paper feed roller, so that when the platen is turned for line spacing the carbon paper is fed around with the platen, being unrolled from the roll holder and drawn downwardly through the chute.

The device thus briefly described is adapted to have usedin connection therewith folded bill sheets of the kind frequently usedv in commercial billing,'each of said bill sheets chute, one of the parts of said bill sheet passing in front of said chute and over the carbon paperand the other of said parts passing behind said c-hute, the fold of the bill sheet engaging with one of the side edges of the chute, whlch thus serves as aside guide.

It will be understood- 4that as the folded bill sheet is fed around with the platen in the usual manner, the carbon paper will be fed around at the same time between the parts of the bill sheet, so that when the printing instrumentalities are operated, one part of the bill will receive impressionsdi rectly from the usual inking ribbon andthe other part of the bill sheet Will receive impressions from the. carbon paper, two copies thus being made. Then the vwriting on the bill sheet has been finished, the latter is fed being lirst brought into coperation with the forwardly out of the machine and is then held by the operator, vwhile at the same time the usualfeed roll release is actuated. Inl

connection with. the rotary material-carrying deviceor roll holder I provide an automatic return for the/carbon paper which is operative to rewind on the roll holder an amount equal to that unwound during the vprinting v operations. The actuation of the feed roll release brings the automatic returning de-4 vice/for the carbon paper into operation, so that the carbon paper which' has been used in the writing of the folded bill sheet will be drawn 'back through the machine until the carbon has leturned tothe position from which it was started when the feeding of the bill sheet in line'space direction Was be'- gun. Thereafter other bill sheets may be written and the carbon automatically returned in the same way until its printing surface has become exhausted, whereupon the exhausted portion may be fed forward and detached by meansl of a cutting blade provided for'the purpose so that a fresh portion of carbon may be employed for writing a plurality of succeeding bill sheets.

, The invention is shown as applied to the No. 4 Smith Premier typewriter which is a machine of the rocker-platen style and the lower portion of the chute is pivotally connected with the platen frame so that said chute is substantially tangential of the platen in either of the positions to which the latter may be rocked,.the arrangement conducing to a smooth andA easy feeding of the carbon to the platen. It is to be understood, however, that various features of the invention are not limited to any particular style of typewriting machines and may be readily 'adapted to other' forms of writing machines.

In the accompanying drawings, Figure 1 is a side View, on a reduced scall/e, of theupper part of a typewriting mac line showing. 'my invention applied thereto, the platen and platen carriage being shown in section, and other parts being shown in section and broken away for the sake of clearness. Fig. 2 is a View corresponding to Fig. 1 but showing the parts in the relations in. which they appear when the platen is rocked forward to expose thewriting. Fig. 3 is a front elevation of the upper part of a machine with my invention in place thereon, vparts being ,broken away. Said Fig. 3 is drawn to a somewhat ylarger scale than Figs. 1 and 2. Fig. 4 is a full-sized fragmentary front. elevation of-my novel paper supply and paper feeding devices, the material-carrying sleeve or roll holder and its casing and bearings being shown in l'on itudinal section and parts being omitted an broken away. Fig. 5 is`an enlarged fragmentary side View partly in section of the carriage and its bearings, part of my invention being shown in combination with said carriage. Fig. 6 is, an enlarged side View of the paper cutting blade in operative position, the support of Said blade being shown in section and the platen being diagrammaticallyillustrated.

Fig. 7 is an enlarged side view of the lower part of the chute or guide-way andshowing the'position of the carbon paper and the folded bill sheet in relation to said chute, the platen and paper feed roller being diagrammatically lllustrated. Fig. 8 is a fullsized transverse sectional View of the roll holder. its casing or cover and the upper part of the chute or guide-way. Fig. 9 is an enlarged face view of a part hereinafter termed a bearing block. Fig. 10 ,is a erspective view on a reduced scale of a fo ded work sheet or bill sheet of the character preferably employed with my present invention.

In the drawings, corner posts 1 of the machine frame sustain a top plate 2 on which are fixed a pair of track ways 3 which are longitudinally grooved to receive antifriction balls 4. Coperating with the balls are grooved front and rear bars numberedA respectively and 6, said bars beingjoined at. their endsby side bars 7 and 8 and constituting with said side bars a platen carriage. Each of the side bars is provided with an upstanding arm 9 and has an inclined slide-way 10 which coperates with the axle or shaft 1'1 of a platen 12, said axle being journaled in a platen frame comprising side bars 13 and 14, a frontbar 15 and a rear barvl. The side bars of the platen frame are provided'with upwardly xtending portions 17 and 18 from which project lateral studs 19, said studs normally engaging with the hooked ends 2O of spring controlled latches 21 pivoted at 22 in the portionsl 9 of the side bars of the carriage. A finger piece or lifting handle 23 is Secured to the front bar 15 of the platen frame near its left end. The normal relations of the platen, the platen frame and carriage are illustrated in Fig. 1. lt will be understood that -when the lifting handle 23 is raised the platen is rocked ,forwardly Vand upwardly, the platen axle sliding and turning on the ways 10 and the platen being rocked forward to the position illustrated in Fig. 2 100 .to expose the writing.

It is not deemed necessary to describe the construction and mode of Voperation of the carriage and platen frame at greater length, as these parts in themselves are not my invention and are well known in the art. The carriage, it willv be understood, is controlled by a spring drum-and step-by-step feeding devices which cooperate in a known manner, when the usual printingkeys are actuated, to move the carriage a letter space ,-27 which extends longitudinally of the platen at its rear (Figs. 1, 2and 5). The 125 lower ends of the links 25 pivotally support at 28 a paper plate 29, said plate being maintained in coperative relation `wlth the platen by the rearward extensions of resihent paper fingers 30 supported on the front 130 studs 34 projecting rearwardly from *theV arms 3l and saidv leaf springs are main-` tained in engagement with said studs by shouldered screws vwhich screw into the arms 31 below Athe studs 34. Confined between the portions 33 ofl the leaf springs and the .rear faces of the arms 31 are the curved end tabs or ears 36 of a paper table 37, said' paper table extending downwardly and forwardly toward the platen as best` shown lin Fig. 1. yA feed roll release lever -38 isfixed to thefeed roll shaft 26 at the left of the'platen, said lever being provided with a lug 39-which, when the release lever vis operated, coperates -with the rear bar 16 of the platen frame in such a way that forward and downward pressure on the release leveroperates to swing'the feed roller 27 away fromthe platen to release or f ree the paper.

Referring now to my novel improvements,

I prefer to mount them in a frame on the platen carriage which frame may be readily detached when it isnot desired to make use of my invention. Some'of the features of the latter, however, it is to be understood,

' are applicable whether the devices are mounted on the carriage or on the frame of the machine.

` My novel lmprovements are especially usevful in billing work..ar.d as in such work a tabulator isl'c'mmonly employed, I prefer to A,.munt the frame or support for .my inven'" tiorron the tabulator column stop bar.

Referring more' especially to Figs. 2 and 5 of the drawings, a bracket 40 is secured by a screw '41 to the rear'bar 6.of the carriage near its right-hand end, said bracket being provided with a shoulder 42 which prevents rotary movement of the bracket on its screw. Atthe left hand and'rear-of the carriage frame a second bracket 43'is secured by set screws 44 in a fixed relation with the carriage frame. A toothed column stop bar 45 of the usual or suitable construction is removably secured by thumb screws 46, t'o the rear end portions of the

brackets

40 and 43. Near either end the stop bar 45 is-provided with a vertical. opening which receives a vertically disposed frame rod 47, each of the said frame rods being secured in place by a pin 48 passing horizontally through the stop bar 45 (Fig. 5). It will be noted that the two frame rods 47 and the column stop bar45 constitute a U-shaped frame which maybe readily detached from the carriage by loosening the thumb screws-46.

rods 47 by removing the pins 48. Suitably y secured at the'upper ends of the frame rods 47 are bearing pieces 49 which, as best shown' in Fig. 4, are perforated'to providebearings for a rock shaft 50, said rock shaft connecting the upper ends of the frame rods and being held in place by headed screws 51 threaded into the rock, shaft.. at its ends. Crank arms 52 are supported on the shaft 50 by their hubs 53 which are held in fixed relation with the shaft by pins 54, said pins being driven through the hubs and the rock shaft. The free ends "of the crank arms 52 -are perforated to receive shouldered screws 55, .said shouldered screws screwing into heads or end

pieces

56 and 57 of'alcasing for a material-carrying device presently to Ibe described. These end pieces are prefer! ably of cast metal and are joined by a segmental cover or casing proper of sheet metal, said casing being'indicated' by the numeral 58 and, as best shown in Fig. 8, being s`ecured in a fixed relation with its heads or end pieces by headed screws 59.

It -`will be understood that the cover as a whole comprises the

heads

56 and 57 and the body portlonr. 58 and that it is pivoted by means of the shouldered screws 55 to the crank arms 52, so `that said cover may be turned on its bearings in. said crank arms. Furthermore, the rock shaft 50 andthe crank arms may be turned inthe.bearings 49 at the top of the frame rods, so thatthe cover abovedescribed may also haye rotary WVmotion about the axis of the rock shaft 50.

The left-hand head,56 of the casing is pro-'y vided with a central boss 60 having a recess which receives aY bearing plunger 61 provided with a central bearing opening or depression, the stem 62 of said plunger ex-A tending outwardly 'through the bottom of the recess in the boss 60 and being provided with a head or finger piece 63. Between the bottom of the plunger 61 and the bottom of the recess a wire spring 64 is coiled around the 4stem 6,2, said spring tending to force the plunger Ainwardly toward the middle of the machine. The right hand head 57 of the casing is provided with a central hub or boss 65 which is perforated to provide a bearing for a short shaft 66. The shaft terminates at its inner end in a head 67, Said head being provided with a central depression and with a crossvslot'25 indicated by the numeral 68. The outer end of the shaft 66 has fixed thereon a finger wheel 69 which is secured in place by a screw 7G.y The construction is such that endwise motion of the shaft 66 in lits bearing is prevented ley-the head 67 and the finger wheel l 69 but said shaft is capable of turning freely in its bearing unless positively held. The central depression in the head 67 ofA the short shaft 66l receives one end of any axial support or shaft 71 of the roll holder,"

- the surface of the shaft and engaging 1n the slot 68 formed in the headof the short shaft 66. The construction is such that the two shafts 71- and'y 66 are 'always caused to turn l. together but may be separated by moving the shaft 7l longitudinally leftward. 4'By pulling outwardly the head 63 of the spring plunger, the latter is caused to disengage from the reduced end 7 2 of the shaft 71 and said vshaft .may then be readily removed from its bearings. When in-place, the shaft 7l may be turned so that the end 7 Zrevolves in the spring plunger 61, while the opposite end being shaft 66 the .latter will be`causedrv to turn with the shaft 71 and the bearing 65 'of the l short shaft also serves as a bearing for the v upper end shaft 71. ,v

The material-carryii'ig device or roll holder which is mounted on the shaft 71 comprises van inner sleeve 74 which surrounds the shaft 71, the left end of said sleeve being closed by a cylindrical bearing block or hub 75 which is secured in the'sleeve by a screw 76. The inner end of the screw 76 is reduced as indicated a't 77, the reduced end engaging in a circumferential groove Aor depression 78 in the shaft 71. The constructign is such that `while the sleeve and bearing block 75 may .-freely rotate on the shaft 71, relative endwise movement of the sleeve and shaft is prevented bythe engagement of the screw end 7 7 iwith the groove 78. rlhe right-hand end portion of the sleeve 74 bears on a bear:- ing block 79 which is maintained in a fixe'd relation with the shaft 7l by a set screw 80, the left-hand portion of said bearing block being reduced in diameter, as indicated at 79a, to provide a suitable bearing surface upon which the end portion of the sleeve 74' is adapted to turn fr`eely. The right-hand'- vertical 4face of the bearing blocl{.79 is provided with a circularly arranged series of notches or depressions 81, the shape of which is best shown inlfig. 9. Adaptedto enga-ge with the notches or depressions 871 is a 'detent 82 pivoted at 83 in la lug 84 projecting inwardly from the right-'hand head 57. The or shank 85 of the detent is bent outwardly at right angles to the body p ortion and passes freel, through an opening 86 in the head 57,'sai Ashank being provided at its-outer end withla` nge'rhutton A fixed in the head of the short coiled spring 88 engages the button 87 andl tends normally to maintain the detent engaged with one or another of the notches 81,l

thus serving to prevent rotation of the shaft 71 inits bearings. When the linger button 87 is pressed inwardly, however, the detent disengages from the bearingblock 79, thus freeing the shaft 71. I employ a detachable spool having a core 89, whichfwhen said spool is in position on the device, surrounds the sleeve 74, constituting a sort of outer sleeve, said core or outer sleeve being 'provided at its ends with flanges 90.' The fric tion between the inner and

outer sleeves

74 and 89 is sufficient to cause them to turn toi gether or, when one of them is held fromturning to cause the 'other one also to be held from turning. lithin the inner sleeve 74 and surrounding the shaft 71 is a coiled spring 91, the right-hand end of said spring being fast in the block 79 and the left-hand end of said spring being fast in the block 75. The carbon paper, duplicating strip or other material is wound on the spool as shown at 92. The construction is such that the paper'may be unwound by pulling on its free end. Then the roll holder, comprising the spool and the inner sleeve, is thus turned, the bearing block` 75 turns with it while the bearing block 79, together with the

shaft

7,1,

held motionless by the detent 82,4 the result being that the spring is wound to in-. crease the tension thereof. lVhen, however, the detent 82 is operated to release the block 7 9, the block and the shaft 71 may `be turned together with the roll holder without affecting the tension ofthe spring 91. The spool carrying the roll of carbon paper may be which normally is in the position'shown in` full lines in Fig. 8. but' which may be moved or swung upwardly to the position shown .by the dotted lines in said figure inorder that the carbon roll holder may be exposed for'removal or other purposes. As shown in Fig. 8 the lower edge of the cover 94 termi nates a short distance in front of the lower portion ofthe casing 58, leaving a space, which is represented in Fig.- 8 by the numeral 95, thro-ugh which space the `free end of'the carbon may be drawn.v Except for this space or slot, the casing completely 1ncloses the carbon roll holder when the cover 94 is closed, so that the carbon is. not exposed to the air and may be preserved from deterioration. l

A chute or guide-way or other material carried by the roll holder is provided `in order that the said carbon paper may besnitably guided downwardly' for the carbon paper coperate therewith. Ipreferto makethis 8 of the drawings. When thus formed integral withv the casing it will be understood that the chute is -held in place by the headed screws 59. The side portions 97 of the chute are bent inwardly toward each other as indicated at` 98 forming grooves or slots 9.9

through which the edge portions of the car-`A bon pass and are guided. The chute eX- tends` downwardly and forwardly toward the platen, being normally arranged in a plane substantially tangential of the platen at the rear thereof as clearly seen in Fig.

1. The lower edge 0f the chute terminates just forward of the top of the paper table 37 and said lower edge is inclined upwardly from leftto rightas indicated at 100 (Fig. 4) fora purpose presently'to be described. A sheet-.metal strip 101 best shown in Figs. 4 and 5 is secured at the lower left-'hand portion of the body of the chute by means of rivets 102. The lower endv of the strip 101 is twisted at right angles tothe body portion as indicated at 103 and is formed with an opening 104 which receives a shouldered screw 105, said screw being threaded into a smallbearing plate 106, which yplate is secured.' at the rear of the left-hand arm 31 in a'fixed relation therewith by means of the stud 34 and screw 35. The shouldered screw.

105 forms a pivotal bearinfr for the strip 101 and through said strip the chute or the guide-way is thereby pivotally connected with the platen frame and platen. Guide wires 107 'are 'suitably secured, as by soldering, to the frame rods 47, two of said guidel wiresgbeing shown, one arranged above the other and both extending. downwardly from the left-hand frame rod 47 to the right-hand frame rod, said guide' wires, when viewed from the side, bowing or curving forwardly as shown'clearly in Figs. 1, 2 and 5.

A suitable severing device for the mate-,

rial carried by the rollA holder is provided at the front of the platen, said device comprising a cutting blade 108 secured by headed screws 109 to bearing arms 110, said bearing arms at their lower ends being curved (Fig. 6) to partially embrace the cylindrical front bar 15 of the' platen frame. The bar or rod 15 is pro-vided at itsA rear with a longitudinal groove 111 which lcooperates withA the curved lower ends of spring plates 112 to maintain the bearing plate normally in 'the position shown in Fig. 5, said spring plates 112 being secured at their;upper ends fto'the cutting blade by the screws 109.' The cutting blade is adapted to be swung rearward'ly and downwardly against the ten- Y sion of the springs 112 to the position shown in Figft, where the cutting edge engages with the platen or the paper thereon, so that the paper may be readily severed. .When

rower part 114, the two parts'joining at one side along their longitudinal edges in afold or crease 115. The narrow part 114 of the bili sheet is suitably ruled and forms the bill proper which preferably vreceives impressions directly from the inking ribbon. 'I he wider part 113 preferably receives impressions from the carbon paper or other transfer medium. ,After the bill has-been written the two parts are separated along the fold or crease 115 and the forwarded to the customer whi e the part 113 is Apreferably vincorporated in a book which forms part of the records of the business, said sheet 113 being preferably provided with holes 116 with which may coart 114 is operate the pins or other vretaining means in the record book. Prior to my present invention the writing of bills` of this characviding a rotary material-carrying device or roll holder which is capable of a pluralit of complete rotations and' is associated wit means for turning the roll backward automatically as far as it is first turned forward,

frequent .handling of the carbon paperis I avo1ded and rapid and accurate writing of the bills isgreatly facilitated.l

At the beginning of the work the parts of the apparatus are positioned as shown in .Fig..1 and the free end of the carbon paper 9 2 is passed downwardly from the back of the roll through the opening or space 95 andl is entered in the grooves 99 in the chute. Before the free end of the carbon is drawn downward through the chute, therelease button 87 is preferably pressed inward, releasing Vthe block 79 and shaft 7l, so that thereafter as the free end of the carbon'is-drawn downward through the chute toward the plate, the carbon roll holder is turned in the direction of the arrow in Fig. 8 andthe shaft 71 is'turned with said .roll holder, the two parts being connected'fon-this purpose by the spring 91 which 1s stiff enough to cause the roll holder and shaft to turn together withoutputting` the spring 91 under tension. The carbon is drawn downwardly until its leading edge passes out of--the grooves in the chute and over the paper table 37 and is brought into Alcoperation with the platen and the paper feed roller, the latter being preferably moved to releasing positionI until the leading edge 'of the carbon has passed between said 'feed roller and the platen. Thereafter the I 10 finger button 87 may be released, causing the deteht 82 to rengage with one ofthe notches 81 in the block 79, so as to hold the shaft 71 from any further rotary movement. One of the folded bill sheets may now be arranged in position for Ibeing fed into the machine. With its bottom uppermost and with the fold or crease 115 at the right, said bill sheet is brought into cooperation with the chute 96, the wideror record part 113 of the bill sheet being passed from left to right. in front of the chute and over the car# bon paper and the bill proper or narrower portion y114 passing behind the chute. The movement from left to rightis continued until the fold or crease 115 engages with the `right-handI edge 98 of the chute. edge is preferably contained in a plane to which the platen axle is perpendicular, so

that said edge 98 serves as a side guide for` the nbill sheet and'positions it so that it may belfed truly and correctly over theplaten.,A

It will be understood from a consideration of Fig. 1 that the part 114 of the bill sheet will be held against the rear face ,of the chute by the guide wires 107. y1f now the platen be, turned in linel spacing direction the bill sheet and carbon will be fed around said platen together,'the carbon as it leaves the chute being inclosed between the two 40, parts of the bill sheet, the carbon. and billsheet together being fed 4out of the machine vat. the front in fa relation with the latter which will be clearly understood from an inspection of F i 3.

part 113 of the bill sheet will be made from' the carbon 92. A

From a considerationbf Fi 4 of the drawings and from what has cdready been said, it will be understood that during the line spacing operations throughwhich the bill sheet passes, the lower portion of the' carbon will be controlled by the laten and,

ythe feed roller, and the roll hol er will be turned to unroll more or lessl of the carbon from theroll. During this turnin movement ofthe roll holder the bearing l'ock 75 wai be tamed with abut the sima or axial This.

Itwill be apparentv 45 that, when the bill-sheet has been fed fari' support 71 and the bearing. block 7 9 will be held motionless by the detent 82, so that the inner sleeve 7 4 will turn on the reduced portion 7 9a of the block 79 as a bearing. Consequently the spring 91 will be woundl up so 70 that its tension will gradually increase, the amountof said increase of course depending on the amount of carbon which is unwound from the roll.A After 'the writing on the bill has'been completed the platen may be turned 75 in line spacing direction until the lower edge of the billhas been moved downwardly and forwardly past the feed roller27. The operator may now grasp the upper portion 'of the bill sheet with the right hand, being 80 careful not to grasp or'liold the free end of the carbon paper, while with the'left hand the feed roll releaselever 38 is depressed to move the feed roller away from the platen. As soon as the'releasing movement of the 85 feed roller takes place, the spring 91, being under tension, acts automatically to turn the roll holder ,in a direction opposite to that indicated-by the arrow in Fig. 8, thereby rewinding the carbon paper on the roll. The rewinding of the carbon continues until the spring 91 has reached its normal state. In other words, the amount of carbon rewoundwill equal the amount unwound after the detent 82 was` allowed to engage and 95 hold the bearing block 79, and when the spring ceases to rewind the carbon the lower a free end'of the latter will be in the position from which it'started when the feeding of the bill sheet around the platen was commenced. A second bill sheet may now be introduced, written upon and fed through the machine as before, the same portion of the carbon again being used to 'reproduce thevtype impressions o n the record portion of said bill sheet. Thereafterv the carbon may be restored to the first position by again voperating the feedroll release lever in the manner above described.

-roll release lever' be operated'the spring 91 will act to rewind the carbon until its lower freeend will have been drawn backwardly around the platen and up through the chute a distance from the feed yroller e ual to-the length of the used portion of t e carbon whichihas. been severed by the'cuttin blade 108. Before introducing the, next bi sheet., therefore, the button 87 ma be pressed in ward to release the shaft .1 and bearing ,la

forward to be torn casing,

block 79 and the lower free end of the carbon may be again drawn down through the chute'until it is brought into the control of the paper feed roller 27 whereupon the button 87 may be released, leaving the parts in the proper position for the introduction of the next bill sheet. 'V

Another mode of operating the parts to secure the same result and which may be followed if desired, is to first press the button S7 before feeding the carbon paper olf. After tearing olf amount and while still holding 87, the paper may be rewound 4by turning the finger wheel 69, to bring the lower end of the paper to the proper position. Each portion or section of the carbon may be employed for writing some half the desired the buttonv dozen or more bill sheets and as the roll holder may carry a roll-of carbon of some fifteen or more yardsin length7 it will be apparent that a large number of bills may be written before the roll of carbon has .all been used. When the entire roll has been exhausted the spool may be slid off theinne1 sleeve 74 .and a new spool and carbon roll substituted.

When during the operation of the machine it becomesnecessary to inspect lthe work, thev lifting handle 23 is raised to rock lthe platen forwardly in the usual manner from the position indicated in Fig. 1 to' that in Fig` 2. During this forward rocking movement 'of the platen "the platen frame will be swungabout the pivots 19 and the roll holder and chute will be swung downwardly and forwardly to the positions shown in Fig. 2. During the downward and forward movement of the roll holder casing, the crank arms 52 will swing .downward, turningthe rock shaft in its bearings 49 whileat the same time the casing i l have a further turning movement in its bearings at the outer free ends of the crank end ofthe chute into feeding engagement with the platen.

arms 52 so that the movement of the casing is a compound one. i It will be apparent that this compound swinging movement of the casing is brought aboutfrom its connection .with the platen frame through the chute 96.

The lower end of the chute 96 is swung forwardly with the platen frame, the pivotal connection betweeny the two permitting an easy change in the relations of the parts. In this new position of the chute 96 it will be seen that it is substantially tangential of the platen at its rear, the consequence of this arrangement being that the back and forth rocking movements of the platen may take place without rumpling or buckling the carbon paper where it passes from the lower If during the operation of the machine a bill sheet has been fed through the machine so farthat the bottom edge of said bill sheet chute.

left to right and by vsheet in its return l on from has passed the lower edge 100 of the chute 96 and it be desired to feed the bill sheet backwardly for correction or other purpose the bottom edge of the part 114 of the bill sheet will first engage near its left-hand edge 'with the bottoni edge 100 of the chute during the backward movement, since the left-hand portion of the bottom edge of the chutel is lower than the right-hand portion thereof. This left-hand portion of the lower edge of the part 114 is free and tends to fall away from the yback of the chute and in practice it will be -found always to fall far enough back to pass readily behind the Consequently as the backward feed` ing movement of the bi-ll sheet is continued the point lof contact between the bottom edge of the part 114 andthe bottom edge 100 of the chute will move gradually from the left to theright, the bottom edge of the bill sheet being forced orA directed rearwardly behind the chute so that the right-hand corner of the part 114 and the fold or crease 115 will be prevented from abutting against the lower edge of the chute 'and will be fed smoothly around the latter, causing the bill sheet, as it is fed backward, again to embrace the chute properly. It will be ap-` parent that-while the left-hand bottom edge of the part 114 tends to fall away from t e, back of thechute, the right-hand part of the ,bottom edge will beheld comparatively close to the back of the chute by the part 113 of the bill sheet .which lies on top of the chute. Consequently if the backward feeding movement of the bill'sheet is further continued the right-hand portion of the lower guide wire 107 will first coperate with the'righthand portion of the part 114 and the point of contact between said guide wire andsaid part 114 will gradually move from the right.

to the left, forcing or guiding the free left-- hand lower edge of the part 114: between the guide wire and the back of the chute. It will be seen therefore that by inclining the lower edge 100 of the chute properly from inclining the guide wires upwardly from right to left,'I provide guiding members which aid' in guiding the bill -movement `so as to feed it smoothly and correctly. When the paper is fed backward as above described, the carbon is rewound onto the roll holder by the spring 91, which keeps said carbon taut and smooth. The carbon itself holds the part 113 of the paper out of contact with the lower edge 100 of the chute 96.
