ATTACHMENT FOR TYPE-WRITING MACHINES..

SPECIFICATION forming part of Letters Patent No. 687,689, dated l\l'ovember 26, 1901.

Application `tiled August 3, 1900. Serial No. 25,775. (No model.)

To 1f/ZZ whom, t may concern/f Be it known that I, I-IUGo C. KRAUsE, a citizen of the United States, residing at Chicago, inthe county of Cook, in the State of Illinois,

have invented a certain new and useful Attachment for Type Writing Machines, of which the following is a specification.

This invention relates to attachments for type-Writing machines designed for produc- Ic ing duplicates of original manuscript-that is to say, for producing facsimiles of ink-ribbon impressions upon two separate sheets of paper and at the same time, if it is desired, a triplicate impression upon a third sheet.

Prior to my invention these ends have been sought to be attained by the use of a ribbon auxiliary to the usual ribbon on a type-writing machine, which auxiliary ribbon is required to be wound upon spools at each end 2o of the machine and have a movement and forward travel corresponding with said usual ribbon and which in addition to spooling necessarily requires the employment of a protecting-strip wound upon the spools of and 2 5 traveling with the auxiliary ribbon.

In the prior constructions above referred to the necessary spooling of the auxiliary ribbon in itself and without regardto the protectingstrip necessarily involves the employment 3o of gears, shafts, and other complex mechanism, such as is common to ribbon holding and adjusting devices in type-writing machines, and also guides for the auxiliary ribbon ,which are not only expensive, but are liable to and frequently do get out of order, and besides which add an objectionable cost to the production of such attachments and a cost which it is desirable to avoid, to which may be added the cost of devices for securing the attach- 4o ment to the type-Writer in its operative position and a correspondingly-increased complication of parts requiring skill in their manipution and constant Watching. Further, in the prior attachments referred to the necessary spooling of the auxiliary ribbon presents the sameI objection and increases twofold that which is common to the 'usual type-writingmachine ribbon-namely, the objectionable handling thereof in inserting it upon and re- 5o moving it from the spools.

One of the important objects of my invention is to provide an auxiliary ribbon in this class of attachments which is not spooled and l which, if desired, need not be handled at all in the objectionable sense referred to with regard to prior spooled auxiliary ribbons.

Another im portant object is to dispense with the use of any necessity for a protecting I, strip or sheet between the ordinary type-Writing-machine ribbon and an auxiliary ribbon 6o for producing either duplicate or triplicate facsimile ink ribbon impressions upon as many sheets of paper.

Another important object of my invention is the avoidance of any necessity forI handling the auxiliary ribbon either in putting it in or taking it out of its operative position in a type-writing machine or of handling it at any time during its operation in the machine.

Afurther object is to produce an attach- 7o ment for type-writing machines for the production of duplicate and triplicate impressions through the medium of an auxiliary ribbon embracing the least possible number of parts consistent with perfect operation and at the same time parts which are simple in construction and require no particular skill for their manipulation in securing the attachment to a type-writing machine or in manipulating the several parts in operating said at- 8o tachment.

With these ends in view my invention consists in certain features of novel construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafterappearing are attained, all as fully described with reference to the accompanying drawings and more particularly pointed out in the claims.

In said drawings, Figure l represents a top 9o plan view of the paper-feed carriage of a typewriting machine with an attachment embracing my invention secured in its operative position thereon. Fig. 2 is a longitudinal sectional view of the auxiliary ribbon roller, 95 particularly showing the relative arrangement of the tube removably sleeved thereon and to which said ribbon is attached. Fig. 3 isa transverse section on the line 3 3 of Fig. 1. Fig. 4 is a transverse sectional end view of Ioo the ribbon tube or roller, as the case may be, particularly showing the construction of a covering-shield, hereinafter described. Fig. 5 is a detail perspective view of the ribbonroller with the ribbon wound thereon, the protecting-shield therefor, and the devices by which the rotation of the roller is limited and upon which it swings to a convenient position for mounting the auxiliary ribbon thereon; and Fig. 6 is a longitudinal section of the ribbon-tube with the ribbon wound thereon, but detached from the ribbon-roller.

1 indicates the front bar, 2 2 the end bars, and 3 the shaft, comprising the paper-feed carriage of an ordinary type writing machin-such, for example, as the Remingtonand 4 the ordinary roller-platen thereof, on the ends of the shaft of which are the thumbrollers 5 5 for turning the same, which frame is also provided with the usual lifting-lever 6, the ratchet-lever 7, the platen-roller-shifting lever 8, the paper-tension lever 9, the paper-guides 10 10, and other details unnecessary of specific reference.

`Secured to the shaft 3 are curved brackets 11 11a, bridging-that is to say, extending over-the platen-roller 4, and secured at their forward ends to the front bar 1 of the paperfeed carriage of the type-writing machine, which brackets may be secured, respectively, to the shaft 3 and the bar 1 by any suitable means which will hold them rigidly in place upon the frame, as, for example, by hooks upon their rear ends engaging shaft 3 and angular clamps at their forward ends engaging the bar 1 and tightened thereon by means of screws or other devices 12, passing through the angular downward extension of the bracket and abutting and tightened against the edge of the bar 1.

The brackets 1l and 1la constitute, together with the shaft 3 and the bar 1, a frame in which is journaled a roller 13, cent-rally through which passes a rod 14, screw-threaded at 15 into a plug or bushing 16 in one end of the roller 13, which plug may be provided with a flange 17 for the purposes hereinafter described; but instead thereof the flange 17 may be screw-threaded directly to the roller 13. The rod 14 projects beyond said flange 17 into the bracket 11, the opposite end of the'rod 14 being likewise iixedly secured in a pivoted bar 18, (see Figs. 1, 2, and 5,) and coiled about this rod within the roller 13 is a spring 19, one end of which is secured to the rod 14 and the other end to the roller 13, so that when the roller is revolved said spring will be put under tension, causing the roller to return to its normal position, the tension of the spring being regulated by turning the rod in its screw-threaded bearing, and thereby compressing or expanding the spring, as may be desired. Bar 18 is pivoted horizontally by means of studs 20 2O at the opposite ends of said bar, which studs are secured to the bracket 11a or formed therewith by means of screws 21 21, projected through the lugs 2O and impinging against the end of the bar, the screws being pointed for this purpose; but any ordinary means for pivoting this bar for the purposes hereinafter described would be within my invention. Between the pivoted bar 18 and the end of the roller 13 and sleeve on the rod 14 is a worm 22, secured to the roller or forming a part therein in engagement with a toothed segment 23, pivoted to the bar 18 or to a lug 24, projecting therefrom. This toothed segment and worm serve to limit the movement outward, and, if desired, toward the extremes of its rotation, as will hereinafter be more fully explained. Sleeved on the roller 13 is a tube 2 5, which may be of papier-mch or other suitable material, to which is attached one end of a ribbon 26, which I designate for convenience the auxiliary ribbon, which ribbon correspends in width to the length of line to be printed, or, iu other words, to substantially the width of the greatest width of paper which can pass through the type-writing machine to which my attachment is secured, the ribbon being of a width and length substantially corresponding with the greatest length and width of the sheets of paper passed through the machine.

The tube 25 is secured to the roller 13, so as to revolve with the roller by having in its end next the worm a slot or notch engaged by a corresponding projection 27 on the piece on which the worm is formed and is held in this engagement by means of an expansionspring 28, coiled about the roller 13 between the flange 17 and the end of the tube 25, the force of which spring maintains the notch in the tube in engagement with the lug 27 when these parts are in their operative position. As shown in Fig. 2, the flange 17is secured to the plug 16 and detachable with the plug from the roller, as is also the spring 28 from the roller, the purpose of which is for the removal and the insertion of the ribbon-tube 25, which is accomplished by lifting the rod 14 out of the slot 25, pulling out the plug and then removing or inserting a ribbon-tube, as desired; but, as before intimated, the plug 16 may be rigidly secured in the roller and the plug 17 be detachably secured by screwthreading it upon the roller, or it may consist of simplya perforated disk slipped upon the rod 14, for it is obvious that in either construction it will be held in its place, though as a disk, such as last described, there will be some friction, which is avoided by either screwing it upon the roller or forming it withV a plug.

1f desired, the spring 28 may be attached to the flange 17 for convenience in handling, and in this connection it is proper to observe that instead of attaching the spring 19 to the plug 16, as shown in Fig. 2, this end of the spring may be secured to the roller and the other end of the spring 19 to the shaft, or vice versa, as to said ends. It should also be observed that my invention includes the omis- IOO IIO

.sion of a ribbon-tube and the attachment of the ink-ribbon directly to the roller, and this may be done by means of a spring clip or clips 29, (see Fig. 5,) shown as a convenient means for removably attaching the auxiliary ribbon to the tube 25; but my invention is not limited vto any special form of devices for attaching the auxiliary ribbon either to the roller or to the tube, and as a matter of fact in so far as the attachment of the ribbon to the tube is concerned it will probably be secured thereto permanently and the tube be thrown away, with the ribbon,when it is worn out, and this for the Very reason that the substantial benet gained by the use of the removable tube instead of attaching the ribbon directly to the roller is that all necessity for any objectionable handling of the ribbon when inserting it to or removing it from the roller is entirely avoided. i

In operation, with the ribbon in its position either by attachment to the roller or to the tube sleeved'on the roller, the free end of the ribbon normally projects under the platenroller of the type-writing machine to about the forward edge of the usual paper-guide 30', (see Fig. 3,) which is forward of the usual feed-roller 3l, and to this end are employed the worm and mutilated gear, which operate as a stop limiting the revolutions of the roller in winding up the auxiliary rib'bon for the commencement of its operation upon a fresh sheet of paper. This will be understood by reference to Figs. l and 2 by bearing in mind that as the ribbon unwinds the mutilated gear will traverse the worm toward the opposite end of the roller and that when the ribbon is released from the feed-roller of the machine and automatically winds up the auxiliary ribbon it will be stopped in its winding movement as soon as the mutilated gear 23 reaches the outer end of the worm and strikes the bar 18 or a stop 23, secured thereto and engaging the mutilated gear 23. My invention, however, is not limited to this peculiar worm-and-gear stop, but includes any. other device by which when the auxiliary ribbon is released from being gripped between the feed roller and the platen said auxiliary ribbon will be stopped at the point indicated and not be entirely Wound upon the auxiliary-ribbon roller, and in this connection it is proper to observe that without a stop of some character the releasing of the auxiliary ribbon from the roller and paper-guide would result in not only winding the auxiliary ribbon upon the roller but of permitting the roller ,to make such a number of turns that it would lose its tension, and thereby require a readjnstment of its tension before again being operated, it being understood that the ribbon even when nearest wound up should be under such tension from the roller as to maintain it in asmooth condition when being fed forward by the feed-roller 31, and, furthermore, that without such a stop the ribbon would have to be handled every time a new sheet is introduced into the machine in order to pro ject it between the feed-roller and the platen for the purposes of its forward feed with the paper through the machine. When-the auxiliary roller and ribbon are in operative position, the usual sheet of paper to be written on (see Fig. 3, indicated at 32) is passed down between the platen and the feed-roller 3l and guide 30 from a point rearward of the auxiliary roller in position to receive impressions from the type striking upwardly against the ordinary ribbon 33, while afterward or at the same time a second sheet of paper 34: is passed downward forward of the auxiliary-ribbon roller to the same position, the front end of the auxiliary ribbon in the vmeantime being held at a point about between the paper-guide 30 and the platen-roller 4. With the two sheets of paper in this position, the type striking upwardly againstv the ordinary ribbon 33 and the auxiliary ribbon 26, the result will be that both sheets will receive a positive impression simultaneously, and as a result there will be two ink facsimiles of letters produced, and if a third one is desired a thin sheet 35 may be inserted with the sheet 32 at a point between said sheet and the auxiliary ribbon, which thin sheet will receive a negative impression from the auxiliary ribbon, but which being thin will appear as a positive when read from the opposite side from that which received the ink. With the sheets in these positions, where there are two or more employed, the result will be that the auxiliary ribbon will be forced by the action of the feed-roller to feed through the machine in a direction at a right angle to the length of the ordinary ribbon, and this feeding will continue until the sheet of paper has entirely passed through the machine, if desired, and until the sheets of paper and the auxiliary ribbon are released by taking off the usual feed-roller, either by releasing the feed-roller or by taking the sheets by the top and pulling them out of the machine, so that the tension on the sheets of the auxiliary ribbon-is overcome by the tension of the auxiliary-ribbon roller, when by the action of its spring said roller will automatically wind up the ribbon until its free end reaches the desired point before referred to, and the further rotation of the ribbon-roller is prevented by the action of the gear-and-worm device, as before described.A In other words, the forward-andbackward movement of the auxiliary ribbon is, by the devices described, rendered entirely automatic and in such manner that during such operation said ribbon does not have to be handled, and by having said auxiliary ribbon secured to a tube removably mounted upon the ribbon-roller the necessity of touching the ribbon with the hands at anytime is entirely avoided, for it will be observed that by leaving the desired length of free end un- IOO IIS

wound from the tube at the time of its inser'- i tion said end, after the tube is placed on the cylinder, may be dropped bygravity between the feed-roller and the platen-roller and be afterward carried by the feed of the typewriting machine to the desired point before described and that therefore there is no necessity of handling the auxiliary ribbon during its operation or when removing it from the machine.

When it is not desirable to use the auxiliary ribbon, the ribbon-roller may be swung forwardly, the tube be withdrawn from the engagement of its notch with the lug 27, and then turned until the ribbon is entirely wound up, when by inserting over the coiled ribbon a tubular spring 36, (see Fig. 4,) said ribbon will be protected from dust and prevented from soiling sheets of paper passing through the machine.

Ordinarily no protecting-strip need be used; but if for any reason one should be desirable a common sheet of paper may be substituted for the sheet 35, which in itself becomes a protecting-sheet when a third ribbon copy is being made.

It is obvious that the employment of an auxiliary-ribbon roller such as I have described is the simplest and cheapest possible means for directing the movement of an auxiliary inking-ribbon, and, moreover, it enables the dispensing of a number of tension feeding and reverse-feeding devices necessarily following the use of auxiliary ribbons, which have been heretofore invariably and necessarily spooled.
