To all whom it may concern: y

Be it known that I, Cnnluns E. FOSTER, a citizen of the United States, and a resident ofWashington, District of Columbia, have invented certain new and useful Improve# ments in Duplicating Devices for Type'- Writers, of which the following is a specifil cation.

My invention relates to typewriting machines and has for itsobject to avoid the necessity of the use of separate duplicating y carbon sheets in printing duplicates, and more especially to avoid the delay and manipulation required for the use of such sheets in duplicating bills upon folded sheets, and to this end my invention consists of a roll supporting a duplicating strip, with means whereby the latter can be brought in proper relation to the sheets to be printed, and with l means for automatically turning the roll when draft upon the duplicating strip is released, las fully set forth hereinafter and as illustrated in the accompanying drawing, in which:

Figure 1 is a transverse section of sufficient of a Remington typewriter' to illustrate the application of my invention in connection therewith; and .with the use of separate original and dir licating sheets; Fig. 2 is a face view of the evice as adapted for at taclnnent to the Remington typewriter; Fig. 3 is a perspective view illustratingl another form of a device especially adapted for use in connection with folded billing sheets; Fig. l is an edge view of the device shown in Fig. 3; Fig. 5 is a b'ack view of part of the device; Fig. 6 is a transverse sec tional elevation showing the device in a somewhat different form as applied to a Monarch machine; Fig. 7 a back view supported by a frame D supported in any suitablemanner, referably detachabl ,upon the carriage, an with the roller C 1s oombined a spring S or weight, or other means whereby, when the duplicating sheet is drawn away from the roller, it will be rewound thereon by the power of said spring or Weight. For many purposes an ordinary spring curtain roller may be em loyed, the Hattened end of the non-rotatale spindle 1 of the said roller fitting a slot :c in one of the upturned ends 2 of the frame D. Against the platen B bears the presser roll 16 and the roll 4c carried by the rocking frame E, which is swung in one direction by a spring 5 and which can be rocked to carry the pressure roll away from the platen by means of an arm 6.

As shown in Figs. 1 and 2, the duplicating devices are supported upon the usual detachable plate F of the typewriter, which is of the Remington type.

The parts are so adjusted that when the roller is wound up to the greatest'extent, there will be a free end or part of the-sheet V extending from the roll to a position near the platen and adapted to be grasped at one or both edges by the operator, and as the sheet V is narrower than the platen, and wider than the plate'F, which may be cut away at the sides, the usual bill sheet or original sheet X may be passed above the plate F and beneath the strip V, while the duplicating sheet Y is placed above the strip V in the position shown in Fig. 1, when the operator, by pinching the side portions of the sheets together, can pass them downward between the rolls B and 4, until properly grasped, and then by turning the platen roller B by the usual knob, the sheets are carried together into position for the original sheet X to be printed, while at the same time the duplicate will be produced.

After-the printing is effected, the roller B may be turned back until the lower edges of the sheets X and Y pass from between the platen and the roll'4, when they can be readily detached, the spring of the roller C causing the strip or duplicating sheet V to be wound up and carried to its original position, leaving the end c/ in position to be grasped, or the rolls 4 and 16 can be moved away from the platen when the roll C will ror o Va frame` having a light fabric u stretched over it, as shown in Fig. 6, or of open-work material to reduceweight, and is o such size as to ermit the folded sheet or separate sheets to placed upon' it laterally with one part or sheet below vand the other above the strip V, the roller C in -this case and upward to an eye 10 upon the being supported at the top of the frame and having a reduced drum 7 at one end, around which is wound a cord 8, the latter passing downward beneath a pulley 9 of a weight W lrame, with the result that when the strip V is drawn upon, the weight will be raised, and will turn the roller and wind up the strip v when draft upon the latter is released.`

In order to properly position each folded sheet in respect to the platen, especially when it is necessary to print at successive times upon the saine folded sheet, and therefore desirable that it should on each occasion occupy the saine position as before in respect to the platen, I provide a guide G snitably arranged between tlie platen and the roller, whereby when olie part of the folded sheet is passed beneath the Guide and above the strip, until the folded until grasped by the same, when the print.

ing maybe done as usual. lAfter the desired printing is effected, the removal of the printed 'slieet or sheets may be effected.

The device in Fig. 6 is shown in connecttion with a machine like the Monarch,

where there are two presser rolls 4 and 16, both of which may be carried from the platen by the operation of a lever 6. In

`the construction shown in Fig. 6, the weight hangs directly fiom the cord without the intervention of the pulley 9 as in Fig. 3, but iii each ease a suitable guide rod 12 at the rear of the frame may pass through the weight o i through an eye 13 on the weight and guide the latter and prevent it from swinging.

the use of a weight as described, the tension tending to turn the roll and lift the sheets etdge of the sheet,l bears against the edge of the guide, the

sheet is uniform, while in the case of a spring it will increase as the spring is wound up, but this latter result may be revented forming the drumwith a gra ually increasing spiral groove 15, as shown in Fig. 8.

In Fig. 7 th plate carries at the rear a drum H in which is a sprin 20 tending to turn the drum so as to win up the cord 8 and turn the roller C.

, In order to properly connect the vstrip Vl to the roller C, the latter may have a lon tudinal groove 1'?, Fig. 9, above which t e end of the sheet may be placed, a strip or rod 18 being then forced inward so as to double the strip around it and secure it to the roll.

It will be'evident that the frame or plate between the roll and the platen may be vertical or horizaiital or inclined, as may be desired, and that the plate serves as a snpport for the strip of duplicating material, holding it in position to permit the paper sheets to b'e properly applied and preventin tearing and injury. It will further be note that the free end portion of the duplicating strip is normally so disposed on the supporting plate that not only the side edge por.

tions but the lower end or edge ortion of the said stri can be manipulate lso that a bill sheet folded along its to ed e may be applied top downward to tie uplicatiiig strip so that the strip will be embraced between the folds of the bill sheet and the end of the strip will lie within the horizontal biglit or fold of the bill sheet.

Without limiting myself to the precise construction and arrangement of parts herciii shown, I claim:

1. The combination with a carriage and platen ofia t pewriting machine, of a roll iaving a dup icating strip Wound thereon, a support arranged to hold said roll above the carriage to normally resent a portion of the strip between the roll)and the carriage with the side edges and lower edge exposed to be manipulated, and means for turning the roll to rewind thereon any part of the strip dravsfn from the roll. f

2. The combinationwith acarriage, platen and presser rolls of a t pewriting machine, of a roll having a uplicating stris wound thereon, a 4support arranged to hol Cri the roll above the carriage to normally pre- @Het lloose or free end of the strip being left platen and presser rolls of a typewritingmachine, oa roll supported on the carriage and having#A -a duplicating strip Wound thereon, to normally leave a loose end enn tending between the roll and the platen in position to permit the lower edge andv side ed e portions to be grasped between the rol and the platen, and means for moving the presser rolls toward and away from the platen.

6'. ln a typewriting machine, the combi i nation of a rotary ,material carrying device capable of a" lurality of complete rotations to unwind t e material, means operative automatically to turn said device through a plurality of complete rotations to rewind a vstantially to the portion of the material, and for controllin the parts so that the portion ofthe materia revvound on said device shall' be equal sub- (portion previously un- Wound, all arrange to expose 4the material below the carrying device so that the lower.

edge and the side edge portions of said material may be caused to coperate with a bill sheet havingV a horizontal folded edge.

7. In a typevvriting machine, the combination of a holder 'for a roll of carbon paper, pa r feeding devices adapted to feed to nfet er the carbon paper from said roll holder and-the paper to be Written upon, a

,ete i supporafor the paper and the carbon sheets between the platen and the roll, means for means for rewinding on said roll holder the portion of the carbon paper that has been unwound from said roll holder'by the paper feedin devices, all arranged to expose the paper eloW the holder'so that the bottom edge and side edge portions of the paper may be brought into coperation With .a Work sheet having a horizontal folded ed e.

8. ln a typewriting machine, the com ination of a carriage, a rotary roll holder arranged above the carriage, an axle therefor, a sp1-ing connected with said rroll holder, paper feeding devices o erative to draw the material from Said rol holder, the tension of said spring being thereby increased, and

a lixed relationship with its bearings, the roll holder 'being arranged to sup ort the '.'l'ree end of the pa er exposed4 belldw said roll holder so that t e bottom and side edge portions of said paper may be free and accessible.

nation of a carriage, a platen, a roll carrying a' duplicating stri and means for turning the roll`to 'reWin the strip thereon, all arran ed to lexpose a art of the stri above so that. the side edges and bottom edge of thev strip are free and accessible and occupy a positlon-between the roll and the platen when the roll is in normal position. ln testimony whereof I aflix my signature in presence or two Witnesses.'
