MANIFOLD ATTACHMENT FOR TYPE-WRITERS.

I Application 11126 October 27, 1918, Serial No. 797,386. Renewed December 23. 1916.

which the 't'ollowing is a full, clear, and ex-- act description, reference being had to the aeronn'mnying drawings, forming part of this'spocification. My invention relates to attachments for typewriting niarhincs designed to hold and supply the paper for the type printing mechanism in continuous rolls, and in which provision is made for making. manifold copies by means of supplemental inking ribbons. I Y

.The invention also relates toan attacln ment for typew'r iting machines that farnishes means wherewith a. plurality of copies maybe produced at one and the same type ke peration of the ty'pewriting machine.

The object of my invention is to provide a manifoldingattachment which can be quickly and easih-"conncctrd with and disronnorted from the typewrii'ing machines, of the visiblewriting class. so to construct and support said inanii'olding attachment that the inanifolding ribbon and the parts immediately cooperating therewith can he moved intoinoperative positions to permit ihetypewritor to be used in the usual man ner without interference between the same and said manifoldint attachment.

I propose to apply my in ention prinoipally to maehinesof the type wherein the sud )lv stationery for H'Odllfilll'" the various of the co nes is wound on rolls, which enables an automatic feed of its web around the platen writing machine; however. I lay no claim to the means shown for mounting such stationery supply for use. I. however, rovide in my attailnnont a horizontally ixed knife edge bar for the purpose 'of cutting the written members into sheets of any desired length. i I. provide a (onstriution whorcwith a pair of ribbon spools upon which the same is mounted' together with a. number of merhanicalembodiments cooperating therewith is provided a labor saving device that will bvnhlit the business world.

The methods now generally adopted provide horizontal position so that the of the writing machine may contact therewith. If the Contact is irregular and the layers of ribbon stretches do not perfectly aline or sag away one from another, it will be readily observed that it will not be pos--' sible toproduce accurate multiples of copies means to guide the ink ribbons to a" type keys of writing with the aid of such multiple i in cases where the ink ribbons or carbon and nonshifting with the carriage of the writing machine in and between the stationory' supply, the uniform impression gained from the ribbon would be lost. I, however, provide, as specification, means so that the multiple folds ofiink ribbon pass perfectly alined to and fro at all times, maintaining a free ribbon shift, producing, therefore, continuous inking renewal and the possibility for pr dueing legible copies of writings.

a dot ll rah-hot vonStintl V Vie Of one of thoboa-ring i get as h ever eb o Pap r fdrawli r m of the well known constructions of typewriting machines for visible writing, but the particular construction of typewriter v with which I have chosen to illustrate my i provements is the ty ewriter known as t e Underwood, in whic the framework of the machine is indicated by 1, the keys by 2, with theimpre'ssion cylinder or platen 3 mounted in acarriage 4, which is arranged to be shifted hy the operation of the space key to carry the paper from side to side as the writing rogresses. In this form .of

machine, the inking ribbonfi is'mounted on two horizontally disposed spools, one of 5 which is shown at 6 in Fig, 2, which spools are suitably journaled one onone side and the other on the other side of the central portion of the machine, withthe ink ribbon carriedin front ofthe impression cylinder or-platen, and between which and the rib bon the paper to be written on is passed to receive the impression from the type selected by the keys operated. For the purpose of. advancing the paper for the spacing, the

impression cylinder or platen over which the aper is carried, isrotated by means of the ine space lever 7 ,pivoted at one side of the carriage frame.

- My improved attachment for such a typewriter consists of devices for supportinglthe supplemental inking ribbon from which the manifold copies are printed, and of the'devices for feeding this ribbon from side to side to present continuously a fresh portion thereof to the type during the operation of the machine. a The construction for holding the rolls of paper is particularly illustrated in Figs. 1 and 9, in which a metal frame work is provided, comprising vertical sidestandards 8, 9, with cross bars 10 at thetop and at the bottom-12. This construction as hereinafter detailed comprises" no part of my invention.

The lower portion ofthe frame is sup- 5 ported in such'a manner as to hold the same against moy ernent, toward or away from the typewritep; but to permit the, frame to move freely inthe'direction of movement of the papencarriage-of the typewri' ,r. This may e accomplished in various ma ners, and, in the present instance, I have sh wn the bottom. 12 as rovided withjournal earings for the s ind es of a pair of grooved carrying whee s 13,14, by means of which} the frame '5'5yis supported on 'the track 15 to be carried from side to side, with the reciprocal move- :ment of the carriage of the typewriter, and to which the frame is secured as willlbe here inafter described.

I 3 At suitable points on the uprights 8, 9,

' of the roll-paper frame; angle plates 15,16, are secured",'- s |,1pported so that the rolls of paper 19,20, 21;;a'1-1d92 can be readily and;

" easilym ouli'tedin' the frame to rotatefreely writer.

the rolls. On the end of the paper rolls in which the spindles are supported in the plate 16, the rolls are preferably provided with disk washers 23, to prevent the paper from coming in contact with the standard, while on the opposite end the disks are omitted, and a tension device'25, 26, is provided to bear against the end of each roll of paper to maintain the proper tension on the paper.

The track 15 upon which the paper roll frame rides is properly supported at the bottom and rear of the typewriter frame by the brackets 29, which brackets are support ed and rigidly secured to the main remework at 30, 30, by screws or otherwise; while the roll paper frame is heldin vertical po-- sition to be moved from side to side with the movement of the typewriter carriage by arms 31, 31, which are pivotally secured to the carriage attachment and at the outer ends are hooked over studs on the-roll paper frame at 32, 32.

From the foregoing description, it will be evident that the typeof paper rolls and supports, arbitrarily chosen to be illustrated here, is such that the roll paperframe may be readily and .easily secured to the type- 4 writing machine without interfering with or altering the machine structure in any way, and also that it is independent of the manifolding to be now described.

The manifolding device proper comprises a supplemental or manifolding ribbon which is supported upon a frame mounted on and movable with the paper carriage of the type- This frame also carries novelly shaped punched shields about which the inked ribbon is drawn to cause a plurality.

of folds thereof to extend parallel with the platen and between the same and the type carrying member at the point of contact of the type with the platen. This frame is preferably pivotally mounted on the paper carriage to permit the ribbon sracks and, the ribbon to be moved upwar ly and rearwardlyto carry the ribbon into an inoperative-position, thereby permitting the typewriter to be used in the ordinary manner i without any interference with the manifoldinglattac'hment, Further, by moving" the much easier to thread the several webszof paper between the various folds of the rib- Theframe for holding and shifting the supplemental inking ribbon for the manifold copies compriscsxvertical end plates 33,

this elevated or inoperative position, it is serves as a cutting edge for serving the webs of paper from the roll after they are written upon, in such lengths as desired.

The framework is pivotally-mounted in 5 bearing pla the and bars 35.), 40, of the typewriter carria e.

the ribbon spools are fresh portion of the rib hon to the type.

By providing loosely mounted sleeves for v} in the plate 37, while omiosite end (Figs. 8 and 13) the stud (mposite end. to receive the the bar. is nm'nntlly tween the spools 51, 52 may be utilize for making a plurality of duplicated copies at the same time that the main ribbon is used for the original inipreesion, I employ a pair of frames 70, 71, de iiending from the end walls 33, 3% of the attachment. The frame is provided with a partially right triangular shield 72, around the diagcmal edge of which the ribbon is carried and-turmrd atright angles parallel to the main ribbon in front of the impression cylinder, and thence to the shieldfil. upwardlythrough the slot 73, thenee'over and. around the projecting arm 74 and back underneath the shield 70,a.round the arnr75 and back between the two folds of ribbon, around the diagonal edge 76 of the shield 71 and them-e to'the spool 52. In this way, three sections of the single ribbon (35) are presented togl-ather with the luain ribbon in front ofthe impression cylinder to receive the impression from the type, and provision is thus made for manifold imprints from the type.

It will be noticed that in winding the ribbon around and through the punched shield, the sections ol the ribbons from end to end are all in close contact, and even at the ends of the lines of printingza clear impression can be made from the type. Inasmuch as the supplemental ribbon is nmunted' on the reciprocating carriage, while the main ribbon is mounted-on the fixed frame of the typewriter in which frame the type bars are mounted, the supplemental ribbon must lie in close contact with the impression .ryli-nder throughout its length. If at the ends the thickness of the shields interrenml between the inking ribbon and the cylinde impressions might be blurred or As already stated, 'the cross bar 3(iprorides the cutting edge for severing the paper from the roll. and" in order that the paper strips may be held tightly against the knife barwhen being! torn off, I provide abar 78 (Fig. 5) to cooperate with the cutter. This bar isliiountrd in arms 79 pivoted .at 81. to the end plates ea; :54 ot' the attaeluuent, and

held, away from the cutterbar by the springs 80 attached between the arms and the end plates. .At onelend an extension a rm S52 is provided for the bar 78, by means of which the bar may be brpugl'it into contart with the cutter to hold the paper passing between the two bars.

In order to hold the attiu'hment rigid in position, a air of ram plates 83, 83 (F ig. 4) are provided, onefor each end 33, 34 of the frame, which are arranged to seat over the ends 39, 40 of the typewriter carria e,. and in order to raise the attachment for t e convenient threading of the paper, I pro vide afinger pull 84. To rovide proper tension for the supplemental ribbon s ools 51, 52, each is provided with a ro ler 85 bearingon the periphery of oneof the spool disks. Each .roller is mounted in an arm 86, pivoted at 87 to its respective end plate 33, 34, and the tension is adjusted by a coiled spring 88 attached to the endwall and to a rod 89 v adjustably mounted on the arm 86 and adjusted by the thumb nut 90.

If roll paper stationery is used to load the machine, as is preferred and has been described, the paper rolls are first mounted in the roll frame as heretofore described, and the paperwebs 91, 92, 93 and 94 are passed .over the ide rods 95, which are mounted on stan' ards 96 on the arms 31 which brace the roll frame in position. The per webs are then passed under and. par tially around the im ression roller, the web 91 in contact with this roller, with the strips of inking ribbon interposed bet-ween the sheets. In order to accomplish this conveniently, the .ribbon attachment is first raised by the finger ull 84, and then the attachment is lowered with the sections of the Supplemental ribbon and the paper webs between the main ty ewriter ribbon and the impression roller. he webs oi'paper are then, passed up between the cutting knife and the cotiperatinkb'ar 78, and the paper strips are tom 01? evenly and the machme is ready foruse. l p The pa er web 94 receives the first im pression rom the type, inked by the main typewriter inking ribbon, and the other webs 93, 92 and 91, in the order named, receive their impressions from the. e sections of the supplemental inkinfiribbon. The rolls of paper and the webs t erefrom shift in the ordinary way for the letter spacing and the operation of th'eline space leverrotates the impression; roller to feed the aper for the next line.

ith the operation of the' line space lever, the supplemental ribbon spools are. also actuated as heretofore described to shift the supplemental ribbon. As the paper is fed by the impression roller, it is; carried u over the'guidelate 35, and when a. su v cient length of t as web has been written on, the sheet may be torn ofi omthecu It will be convenient to have the uppermost sheet which vtakes the original impression from thenmainlribbon, nnted'so as to indicatewhen" the proper ength t sheet has been reached.

ith'ihe folds of the ribbon as shown, the proper tension can be maintained on the ribbon, and it can be readily drawn from one receiving spool to the other. By su plying rollers over which the ribbon can f the guide plate to the other, many more folds'of the ribbon can be built up without the ribbon binding in its track.

of the device will be readily d from the foregoing description of the-several arts thereof and it Wlll be apparent that have provided a manifolding device which-can be very quickly and very easily attachedtcand removed from typewriting machines now-hon the market with little or no modificationnr alteration of said machine. The device maybe connected with many of the machines without any change whatever-either in .the machine or in the device. In the caseof s0memachines, however, it may be necessary to make slight alterations to connect the device understoo to the difi'erent sizes and shapes of the typewriter frames By making the spindles of the supplemental ribbon spools reversible it is ossible to adapt the device to machines, the rames of which are ofmaterially different widths with no change other than moving the ribbon spool lock nuts from the inside to the outside of the supporting frame or vice versa. It will also be ap arent that whilewe have shown this mani olding dc vice in the form of an attachment, it can readily be built into the machine, and made a art thereof at the factory. Further, it wil be apparent that the manifolding'dey vices'are so mounted that they can be moved away from "the writing devices of the machine to permit these devices to be operated in the usual manner, and when so operated, the manifolding devices will in no wise interfere with the operation of the typewriter as such.

It will be apparent that I have provided means whereby a plurality of copies may be simultaneously produced from a single mk- I ing ribbon, this ribbon being supported in such a manner as to cause a pluralit of folds thereof to extehd between the p aten and the type at the point of printing.

It will be understood-that while I have shown and described the invention as applied to typewriting machines, many featurcs thereof can be adapted to machines of a widely difierent character. For example,

- the use of a single inking ribbon to simultaneously produce a plurality of copies isby no moms but could be appliodto devices ."ri wi lie ted to writing'machi'nes 35g 9 9 Ma "'9 it I,

It will also be understood that while I have shown, and described one form of the invention, this form is ehosenfor the purpose of, illustration only and I do not wish to be limited to the details of construction. shown and described, for obvious modifications will oeou r to a person skilled in the art.

Iii-hiring thus described my invention, what I claim new and desire to secure by Letters Patent, is:-

l. A nninifolding device for typewritel'e comprising a pair of ribbon spools, carried by the carriage of the typewriter, ovsingle continuous web of ribbon thereon, men for automatically nctmiting the spools for to c'ling the ribbon from one to the other, and ribbon guides mounted on the or riage for supporting a lurelity of folds of said rib-- hon, said gui es having inclosed apertures therein for each fold, and one of said I aides having an inolosed slot and a diagona edge adiacent said slot to permit the ribbon to be doubled on itself, and then passed between the two folds thereof.

2. A menifoltling device for typewriters con'iprising a pair of ribbon spools, carried bythe carriage of the typewriter, a. single oontinuons Web of ribbon thereon, means for autonmticelly actuating the spools for feeding the ribbon from one to the other, and ribbon guides mounted on the carriage for supporting a plurality of folds of said ribbon, guides comprising plates having projecting arms inclosing triimgular openings for directing and from the spools, mid

of the guides for holding and gnarr ing the intermeciiete folds.
