To @ZZ whom, it may concern:

Be it known that I, FRED P. GORIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Attachment for Type-Writers and Similar Machines, of which the following is a specification.

This invention relates to an attachment for type-writers and similar machines and belongs to the class of attachments adapted to produce a plurality of copies and now usually designated as multigraphs.

The object of the invention is to provide an attachment capable of making a single copy, two copies, ora number of copies in a simple and efficient manner and to readily change the attachment to adapt it to make single or multiple copies without loss of time. The most common form of making duplicate copies is by the use of carbon-paper; but such paper is expensive, perishable, and occasions much loss of time in manipulating it to place it between the sheets to be printed upon and to remove it from the sheets after they have been printed upon and in introducing the sheets into the machine by a distinctly-separate operation. By later improvements it has been attempted to produce duplications of printed work in type-writers without the use of carbon-paper; but it has been found difficult to adapt such attachments to make single copies, as Well as duplicates, with facility and despatch. The present invention is intended to obviate the 'difficulties heretofore experienced by the use of carbon-paper and also with the multigraphs just referred to.

The invention embodies certain principles which may be carried out in the construction hereinafter described and will be more particularly pointed out in the subjoined claims.

Like reference-letters refer to corresponding parts in the several figures of the drawings, in which- Figure 1 is a front elevation of the carriage of a type-writer in its lifted position to which the attachment is applied. Fig. 2 is a plan or top view of the same with the carriage down in position to operate. Fig. 3 is a vertical section on the line 3 3, Fig. 2. Fig. 4 is an cud elevation. Fig. 5 is an end elevationv with the ribbon-lifting mechanism in eXtreme up position readyT for the paper to be fed to it. Fig. 6 is an end elevation of the rib bon-moving mechanism in extreme down position, so as to put the attachment outof operative position. Fig. 7 is a vertical crosssection on the line 7 7, Fig. 2. Fig. 8 is a detail perspective view of the ribbon holder and guide. Fig. 9 is a detail 'under View of the wire-holder detached, for the purpose of illustration, from the ribbon-holder, of which it forms a part. Fig. 9% is a detail cross-section on the line 9 9, Fig. 1 of the drawings, and with the addition of a cross-section of the main or usual inking-ribbon. Fig. lO is a detail cross-section on the line 10 lO, Fig. 1 of the drawings. Fig. l2 is a top View of the same. Fig. l1 is a detail section on the line l1 11, Fig. l of the drawings. Fig. 18 is a top View of the same. Fig. 14 is a vertical section in detail of one of the reels for the supplemental ribbon and the mechanism for securing the same to the shaft.

The attachment is in the drawings shown appliedl to a Remington type-writer, although it is obvious it may be equally Well applied to other makes of machines. Inasmuch as the attachment is applied to the carriage of the Remington type-writer, it is not necessary to show the details of the lower part of such machine, but which lower part of course is provided with the usual set of keys, operating-levers, type and ribbon, or other inking device. The lower part of this typewriting machine is in the drawings designated by the letter A. A carriage is connected to slide upon a bar of the lower part of the machine in the usual manner and is provided with the customary features of construction,

which are well known and need not therefore be specially described. This carriage is designated in the drawings by the letter B and is pivoted so as to swing down into operative position or up into position for inspection, as is usual in such cases. It will not be necessary to specifically define the construction of parts of this carriage, as they are well known to persons skilled in the art, and therefore it is to be understood that such parts of the carriage as are not specifically referred to in this 10o specification are of the usual construction and that when it is advisable to describe any particular part which is well known in its connection with features of the attachment a separate reference-letter will be applied to such part. In connection with this carriage there is used the ordinary printing platen or roll, (designated B,) and arranged in a holder, the construction of which will be hereinafter described, there is a supplemental inking-ribbon C. When but a single copy is desired, this supplemental inking-ribbon C is thrown out of the way and not used, the single copy being made by the use of the main ribbon A on the lower part of the machine or any other convenient location where it may be placed. When two or more copies are desired, the supplemental ribbonv is employed and is placed between the sheets of paperin a manner which will be hereinafter described. By way of description of the use of ribbons in connection with one or more copies it may be said that to make one copy the type-bars are used in connection with the main ribbon of the machine, as just suggested, and when two copies are desired an additional or supplemental ribbonis placed between the two sheets of paper, and the type acting through the first sheet and through the supplemental ribbon makes the impression on the second sheet, it being understood, of course, that the raised surface of the type makes a corresponding impression in the first sheet and the supplemental ribbon and thereby is enabled to leave a similar mark upon the second sheet, with which the raised portion of the ribbon contacts by reason of the pressure of the type. However, in this operation not only will these two impressions be made, one on each sheet, but there will also be a third impression on the back of the first sheet, which is not only of no use, because it is a reversed impression, but mars the appearance of such first sheet, .and to avoid this defect provision is made for placing a lremovable protecting-strip C of tape, paper, or other material between the supplemental ribbon and the first sheet,which tape will thereby receive the impression and prevent the mutilation of such sheet. If three copies are desired, provision is made for placing a third sheet of paper (preferably thinner than the other two sheets and in lieu of the protecting-strip just mentioned) between the supplemental ribbon and the irst sheet, whereby this third sheet will receive an impression upon itsback of a reversed character, but which may be read correctly when-looking from the front or other side of such thin sheet. It is obvious that this snpplemental ribbon may be of any convenient .size and shape, according to the occasion or machine on which they are employed, and may be clamped or held in many different ways. An advantageous and efficient mechanism for clamping the supplemental ribbon vand. removable protecting-strip is shown in the accompanying drawings, and consists in hinged plates, more particularly illustrated in Figs. 8 and 9of the drawings. The holder preferred employs three plates for two or three copies, each separable from the other and normally held together by acoiled spring wound upon the pintle or pivot of the hinge andbearing upon the bottom plate. One of these plates, and preferably the top plate,

` may be for convenience termed the fixed plate and the other two plates the hinged plates-that is, the fixed plate has the lugs forming the bearings for the pivot of the other two plates. The fixed plate is in the drawings designated by the letter D, the intermediate plate by the letter' D', and the bottom plate by the letter D2. The protecting-strip C should be capable of being readily removed, and one device for the purpose which has been found advantageous and efficient is t-he holder composed of plates just referred to. The protecting-strip when applied to this holder extends approximately the length of the width of the paper to be written upon and has its ends clamped by the plates of the holder by inserting such ends between the lower and the intermediate plate. It is obvious that with this construction the protecting-strip may be readily removed by separating the plates between which its ends are clamped. The intermediate plate serves as a horizontal guide for the ribbon in that it is provided with overturned edges a, extending horizontally toward the center of the plate and leaving a slit or aperture a',

4.through which the edge of the ribbon may be inserted and drawn until it is practically inclosed between the main plate D and its overturned edges, there being thus formed a horizon tal guideway for the ribbon. The top plate may have an extension at its end to change the direction of travel of the ribbon, and a convenient construction for this purpose is shown in Fig. 8 of the drawings, in which there is a transverse elongated slot about the width of the ribbon, (lettered 1),) through which the ribbon may pass through the plate, and a sloping edge cut at an angle of about forty-tive degrees, over which such ribbon may be turned a quarter-turn and which is designated bythe letter c, and a straight edge at its rear side, which may be provided with a roller d, as shown, whereby the ribbonis given the proper direction of travel to adapt it to wind upon a reel E, as shown in Figs. l, 2, and 3 of the drawings. Any suitable tension device may be employed to give the ribbon the proper tension, and in the drawings there is shown for this purpose a spring-actuated brake e, which brake is fastened to the carriage of the machine and bears at its free end upon one iiange of the drum. In the plate D there may be also fastened the ends of wires F, which wires extend transversely of the machine at a distance apart slightly in excess of the width of the supplemental ribbon and between which the free IIO portioirof the ribbon-thatis, the portion ex- A tending over the platen or roller and upon which the type act-is guided and held. This holding of the ribbon by these wires is effected because the wires are taut and comparatively rigid, while the ribbon with the utmost tension placed upon it is not so rigid, and consequently the edges of the ribbon, being slightly out of the same horizontal plane at different points, catch against the wires, and it is thereby held in place against the feeding action of the paper when the latter is being moved. It is to be .noted at this point that these detaining-wires are an accessory or addition which while advantageous are not necessarily employed. It' this supplemental ribbon is given sufficient tension by any proper device for the purpose, the paper being fed will be unable to overcome such tension, and in such case the detaining-wires will not be necessary; but when sufficient tension for this purpose is given to the ribbon it will require considerable force to feed such ribbon and overcome the tension for the time being, and it is therefore desirable to decrease the tension and thereby decrease the friction to be overcome in operating the feeding device, and to this end the detainingwires are employed and found advantageous.

It will of course be understood that these ribbon-holders for the supplemental ribbon are used in pairs-that is, there is one at each side of the platen, with the ribbon stretched between them and passing through them. This is clearly shown in Figs. l and 3 of the drawings.

During the operation of the machine the supplemental ribbon is of course placed in the typeline-that is, in the line upon which all the type will strike-and is arranged very close to the platen or roller, which receives the ultimate impact of the type. Vhile the attachment may be operated with the supplemental ribbon always in this position, yet the proximity of such ribbon to the platen will make it difficult to place such ribbon between the incoming sheets of paper, and for that reason it is preferred to provide a mechanism adapted to move the ribbon out from the platen, so as to provide more space between such ribbon and platen, and thus enable a sheet of paper to be more readily inserted between the ribbon and the platen. It is manifest that many different forms of mechanism may be employed to embody this principle, and I do not therefore wish to be understood as limiting myself to the mechanism shown and hereinafter described for the purpose; but a convenient and effective device to accomplish this object is illustrated in the drawings as consisting of pivoted arms hung from a center eccentric to the center of the platen in case a circular roll or cylinder is used for the platen. These arms are particularly well shown in Figs. 3, et, 5, and 6 of the drawings and designated by the letter Gr and may be conveniently pivoted, as shown in Fig. 3 of the drawings, upon the sleeve H, Y

surrounding the shaft I, on the ends of which shaft are mounted the reels or drums E, before referred to. It is evident that when these arms G are swung either backward or forward they will carry the holders (which are secured at the free ends thereof) and the ribbon which passes through the holders outward from the platen, so as to leave more space between the platen and the ribbon.

When the sheets of paper are first fed into the machine and their upper edges clear the lower scale B3 on the carriage, such edges of the paper will be so close to the type-line that it will be difficult to separate them in order to pass the sheets of paper above and below the ribbon, respectively, and it is desirable to facilitate the introduction of the paper into its proper position that a greater length of the sheets shall be made to protrude beyond the edge of the lower scale than that portion extending between such scale and the type-V line, and the only way to effect this end is to move the supplemental ribbon and lower scale with relation to each other. The lower scale and supporting parts may be moved with reference to the type-line, the ribbon above the same, or the supplemental ribbon may be moved, and in practice it has thus far been found most convenient and easier to move the supplemental ribbon away from the typeline and the lower scale than to move such scale from the ribbon, although it is to be distinctly understood that the invention is not to be limited to the movement of the ribbon, although that is the preferred arrangement. It is advantageous to move the ribbon for another reason once before alluded to in this specification, and that is because when but a single copy is desired the supplemental ribbon is not to be employed and should of course be moved out of the way. The supplemental ribbon passes through the holders at each end, as before described, and the holders being mounted upon the pivoted arms, which latter swing eccentrically to the axis of the cylindrical platen, it follows that the one mechanism or device-viz., the pivoted arms-performs the two independent functions of lifting the supplemental ribbon outward from the platen and moving such ribbon away from the type-line. These two principles are, as above suggested, entirely independent. and may be separate] y employed without departing from the spirit of the invention; but it is advantageous to combine them in the operation of the machine, and

the pivoted arms just referred to provide a panying drawings and will now be described. A plate (designated by the letter K) is suitably secured to the frame of the carriage, and preferably in a detachable manner, by means of screws n2, as shown in Fig. 7 of the drawings. This plate K projects in the same direction as the pivoted arm at the correspondingend of the machine and has its lower end arranged just above the plate or clamp of the holder secured tosuch arm when the parts are in the position shown in Fig. 4L of the drawings. This lower edge is curved or segmental in shape and provided with a series of notches formed therein. There are preferably three notches, (designated, respectively, by the reference-letters m, m', and m2.) Pivoted to an arm G is a lever L, at one end of which may be a thumb-piece and at the other end of which is a dog n, adapted to engage either of the notches m fm" m2. A spring o bears upon the end of the lever L nearest the dog and tends to engage the dog of the lever with a notch. The dog may be released from any particular notch by pressing upon the thumbpiece at the other end of the lever, and thus lifting the dog out of the notch. Inasmuch as the lever is mounted on the pivoted arm carrying the supplemental ribbon, it swings with the pivoted arm, and as the arm and ribbon are moved to the intermediate position over the type-line the dog engages the intermediate notch m and holds the ribbon securely in that position, or as the pivoted arm and ribbon are moved away from the type-line toward the notch on2 the dog when it reaches the latter will secure the parts in` that position, and thus hold the ribbon lifted from the platen and rearward of the typeline, whereby the sheets of paper may be readily introduced over such ribbon, and when it is desired to make only a single copy, and therefore the attachment should be thrown out of operative position, the dog is released and held out of engagement with the notches and the pivoted lever and ribbon thrown forward until the dog is opposite the `notch m, when it will enter the same and maintain the attachment out of operative position.

As the sheets of paper upon which the imprint is desired to be made are fed into the Vmachine it is desirable to temporarily lift out of the way the paperguides and frictional clamping or feed rolls, so that the upper edges of the sheets of paper may be separated sufficiently to allow the supplemental ribbon to pass between them. In the usual form of type-writer the paper-guides are independent of the frictional clamping-rolls, a slot being out through the upper part of such paper-guides to admit of the passage therethrough of the lower surface of the frictional clamping or feed rolls. Moreover, in such usualform of type-writer there are three sets of paper-guides and frictional clamping or feed rolls, and each set is independent of the other. In the present attachment it has been found ing or feed roll to its paper-guide, so that these two parts will move together. In the drawings the end paper-guides are designated by the letters M M and the central paperguide by the letter N. Likewise the end frictional clamping or feed rolls are designated by thezletters O O and the central roll by the let-ter P. A convenient construction for the end paper-guides and rolls is to hinge such paper-guides to brackets Ml M2, which are in turn clamped to the carriage, and to mount the rolls in the brackets, providing, of course, apertures in thepaper-guides, through which the surfaces of the rolls may project and contact with the platen in the usual manner. By this construction the frictional clamping or feed rolls are carried by the paper-guides, so that such guides and rolls may move together when it is desired to lift them from the platen for the purpose of facilitating the entrance of the sheets of paper. A similar construction may be made at the center; but at that point it has been found more convenient to hinge the paper-guide to the front bar of the carriage and form bearings in such guide for the shaft of the roller, just as is done in the ordinary construction. In the figures of the drawings and more especially in the detail views, Figs. 11 and 13, the central paper-guide N is shown as hinged to the IOO bracket, which latter is clamped by the clamps i N N2 to the front bar B of the carriage. Inasmuch as all these paper-guides and rollers should be moved out of the way to permit the sheets of paper to be spread apart at their upper edges, it is of course desirable to save time by moving them all together, and to this end the shafts of all the frictional clamping or feed rolls are extended, as shown in Fig. 1 of the drawings, and a rock-lever Q is provided at its two ends with slotted arms r, bent at right angles to the same, adapted to engage the ends of the shafts of the end rolls, and with projecting pins s, adapted to project under the extended shaft of the central roller P. This rock-lever may have a handle t, by means of which it may be manipulated, and when this handle is lifted the lever is rocked and all the paper-guides and rollers are simultaneously lifted above the surface of the platen,so as to permit the ends of the sheets of paper to be spread apart. When the paper has been properly introduced and is in position to be written upon, the rollers and paper-guides may be depressed; but the construction of the attachment is such that the central paper-guide and roller are not necessarily depressed simultaneously with the end guides and rollers, because the pins 's only bear upon the under side of the eX- IIO IZO

this is to prevent too much friction being applied to paper which does not require the action of a central guide and roller. In case envelops are desired to be printed upon it is advisable to use the central guideand roller, as well as the end guides and rollers. As a convenient means of feeding the supplemental ribbon the construction illustrated in Fig. of the drawings has been devised. In this construction a transverse shaft I is supported in the frame of the carriage and has loosely mounted upon each end thereof a drum EI upon which the supplemental ribbon is to be wound. end is a :ratchet T. The cylindrical platen has, as is usual, at one end a ratchet XV, which is engaged by a pawl U, operated by a pivoted elbow-lever X. Projecting from the` upper end of this elbow-lever is a journal Y, upon the inner end of which the pawl U is pivoted and upon the outer end of which a pawl V maybe pivoted. TWhen the rock-lever X is moved, it will operate both pawls and cause the cylindrical platen to be moved one step and the reel E, to which the ratchet T is secured, as hereinafter provided, onestep, and thus wind the ribbon upon such reel.

The construction for clutching and unclutching the reels to the shaft is (shown in Figs. 3 and I4 of the drawings, andspecially clearly in this last-mentioned figure. The ratchet T is secured by a pin to the shaft, so as to rotate with it, and has formed longitudinally of its axis a hole f, adapted to receive a bolt Z, which latter is springacted and supported in the reel E. This bolt Z passes through the reel and may enteran aperture f. When the bolt thus enters the hole f in the ratchet, it will lock the ratchet to the reel or drum and cause the two to be secured together and revolve together, and thus feed the ribbon at that side, as before suggested. At length, the ribbon being fed as far as it will go in that direction, it may be desirable to reverse the direction of feed, and to this end a corresponding drum E is loosely mounted upon the shaft I at its opposite end and may be secured to the same s/o as to move with it by locking a washer TXkeyed to the shaft at that end, to the drum by means of the bolt Z at such end, povided, of course, the bolt at the ratchet end of the machine is withdrawn and locked out of engagement With the hole in the ratchet, which may be done by turning it so that a shoulder upon it will engage a stud g on the reel.

From the abovedescribed construction it will of course be understood that in the normal operation of the attachment one reel is loose upon its shaft and the other secured to the shaft and that if, for instance, the reel at the right side of the machine is rotated by the pawl which engages its ratchet T from left to right the reel at the left side of the machine will revolve loosely on the same shaft from right to left because of the drawing act-ion of the ribbon, which is being at Secured to this shaft at one,

the time wound upon the reel at the right side of the machine. On the other hand, if the bolt Z is withdrawn from the ratchet T and secured in inoperative position and the bolt at the left side of the machine is inserted in the .aperture in the washer T then the action of the pawl in causing the ratchet T to rotate will also cause the reel at the left of the machine, which is locked to its shaft, to rotate from left to right, so as to wind the ribbon at that end, and this winding of the ribbon at that end will draw upon the reel at the right side of the machine and cause it to revolve in the opposite direction, and consequently pay out the ribbon. In this manner the supplemental ribbon is fed from one side of the machine to the other and then back again by merely reversing the clutching or locking mechanisni-that is, by locking at one end and unlocking at the other.

Itis clear that the mechanism just described for feeding the supplemental ribbon is not essential, but is merely a simple and advantageous mechanism and the best which I at this time know for the purpose. Persons versed iu this line of machinery will readily appreciate equivalent mechanisms for performing the same function, which, while differing in form, will embody the same spirit, and I therefore do not wish to be understood as limiting myself to the construction described.

Referring now particularly to Figs. 1, 7, and 8 of the drawings, attention is directed to the automatic lifter for the supplemental ribbon. The holder for the ribbon is composed, as before stated, of several plates, some of which are hinged so as to be moved away from t e other or additional plate. This hinge eature is desirable, not only, as above described,to enable the plates to be separated, so that the ribbon may be readily inserted and so that a piece of tape may be inserted, as above described, but also for the purpose of automatically lifting the ribbon farther away from the platen and for lifting the wires and ribbon over the lower scale of the carriage when they are being changed from their inoperative position to a position in which they are capable of performing their usual functions in the attachment. The pivot or axis upon which the plates D and D2 turn has secured to it a lever G', provided with a toe or projection thereon. This toe passes through a slot in the stationary plate D and bears upon the plate D'. A stud or pin H projects inwardly from an end bar of the frame of the carriage in the path of the upper end of this lever G. As the holder is rocked forward to lift it, with its ribbon, above the cylindrical platen and carry it away from the type-line the upper end of this lever G' strikes the pin or stud H and rocks the same upon its axis and causes the toe thereof to press against the hinged plate D and lift the latten, with its ribbon and wires, so that said wires will clear the lower scale and said ribbon be fur- IOC IIO

ther removed from the platen than the eccenprovided with a lever and toe, as just described, and a stud or: pin is correspondingly arranged at each side of the machine to engage such lever, so that simultaneously the hinged plate D of each holder will be lifted,

as specified. Fig. 7 of the drawings shows in detail the holder, which is arranged at the left side of the machine, provided with its lever and toe and in dotted lines shows the position assumed by the parts after the ribbon and wires have been automatically lifted by the engagement of the lever against the pin. Fig. 9% shows the holder at the opposite end of the machine, with the parts drawn upon a somewhat-larger scale and the lever in position to engage the pin, and also a crosssection of the main ribbon which is employed in the machine.
