MANIFOLDING ATTACHMENT FOR TYPEWRITERS.

Application led November 25, 1921. Serial No. 517,473.

To aZZwvom it may concern.'

Beit known that I, MALCOLM L. CossiT'r, a Citizen of the United States, residingat Alameda, in the county of Alameda and State of California, have invented certain new and useful Improvements in Manifolding Attachments for Typewriters, of which the following is a specification. My invention relates, class of manifolding devices for typewriters and similar typing machines, in which one or more manifolding ribbons are mounted upon the platen-carriage of the machine and are adapted to be moved into and out of functional position in theline of type' impact.

In particular, my invention relates to a type of this class, in whichv the manifolding ribbon is carried by and between a pair of spaced arms mounted for swinging movement, whereby the ribbon is carried through an arcuate path to vand from functional position; and, more especially .it relates to a spe-v ciesof said type usinga. plurality of ribbons adapted for independent movement, such a form being disclosed in my pending application for patent, Serial Number 402876, iled August 11, 1920;

`My invention consists in a novel means for moving the manifolding ribbon to and from functionall position, and in case of a plurality of ribbons, for selectively, independently moving them.

The object `ofmy simple, effective, and readily operatable means for this purpose, especially adapted for association with that type' or form of manifolding attachments having the characteristics of the device shown in my application above referred to.

In illustrating and. explaining my present invention,-I shall necessarily show and describe portions end of my in general, to that invention is to providev of the general ,attachment heretofore disclosed in saidapplication, but

In Fig. 1, the numeral 50 is the frame 'of a typewriter; 51y its keys, 52 its main inking ribbon, 53 the-AribbOn'spOOlS, 54 the index 'pointer and 55 the paper guide apron.;

1 is the platen of the typewriter mounted I on its carriage 1 and having the hand wheel l. and the spacing ratchet 2. 3 is a standard secured on the platen-carriage of the machine beyond the end of the platen, one at Veach end, as in Fig. l.

In the' head -of one of these standards, say the right hand one, is journaled a shaft 4, Figs; l 2, 3, 4 and 5, having a thumb-wheel 5, Figs. 1 and 2 for turning it. To the inner of the shaft is fixed a crank member 6,'

extends parallel with, and above and back of the platen to the other end of said platen where it is carried by a crank-member 6",

13, similar to 6, which member is carried by rotatable shaft 4 similar to 4 journaled in the standard 3, secured upon the A5 platen-carriage beyond that end of the 'platen n Upon the rod 7 are carried the sleeves 8, 8 and 8, Figs. 2, 4 and 5'. These are nested, and eac-h is independently rotatable, the in- 10 nermost, 8, being rotatable on the rod 7,-the

next, 8, rotatable on sleeve 8, and the outermost, 8, rotatable on sleeve 8. There may be any suitable number of these sleeves, here shown as three, for example. l

Onthe end of-the innermost sleeve 8 A'is fixed an arm 9; 4on the end of the middle sleeve is fixed an arm 9'; and on the end of the outermost sleeve is`fixed an arm 9. Similar arms, are similarly carried by the other ends of the sleeves. Fig. 1.` 4

Detachably and reversibly mounted upon and extending between each pair of arms is a manifolding ribbon 1 0, 10 and 10 respectively. Figs. l and 2. The base of 25 each arm is formed with a t'oothed segment 1-1, 11 and 11. respectively., These are clearly seen lin Fig. 4.v The shaft `4 is hollow and within it is journaled a shaft 12, on the outerend of which is fixed a thumb wheel iii-Figs.' l and 2. Theinner end ofA this shaft carries a mutilated pinion, the face of which -is provided with tooth. sec* tions in parallel planes,` but in successive Y arcs. Figs. 4 and 6j One section, indicated varm 9; vthe next, 1`4. engages the segment 11" of the arm 9, while the last, 14 enj gages the. segment/11 ofthe arm 9.f It will be noted 'that these tooth sections of the pinion do not followeach other immediately, Ia 'space occurring between the end of one and the beginning of the next. See Fig. 6. This is for a purpose to be present-1y made clear. p Itwill now be -seen that by turning the shaft 12, by means of its thumbwheel 13, through apartial rotation, the pair of arms f 9 with their ribbon 10 may be swung with their sleeve 8 as an axis; and by' continuing the movement of the thumb wheel 13 in the same direction, the pair of arms 9 with their ribbon 10 may be swung with their sleeve`8 as an axis; and finally-by continuing the movement of the thumb wheel the A pair of arms 9 with their ribbon 10 may be moved.'A i v Thus the ribbons may be independently selected to be thrown into and out of use leither singly or collectively accordingto whether one or plural copies are deslred, and, if the mounted position ofthe ribbons were of such a Inature as to make their paths sufficiently concentric with the platen, nothing lfurther would beil needed to carry them fully down,'without Vinterferenc"e 'with any by .14, engages the toothed segment 11 of the` of the parts of the machine, into functional position in the line of type impact: But,

,asfully described in my previousapplication above mentioned, the mounting of the ribbons is best. in a position requiring a distorted path, in which they first move down through an arc on one center, and make their final movement to functional position through an arc on another center, inlorder 10, which is not quite that of its final functional position, said movement being accom- Vplished by operating'the thumb wheel shaft 12, then by operating the thumb wheel shaft 4, the ribbon will, through the actionlof the crank members 6 and 6 which move the sleeve carrying rod 7'bodily forward, descend to its final position as shown in Fig. 11, moving about t-he shafts 4 and 4 as an axis. This operation about two centers is in effect like that disclosed and claimed in my previous application, but the structure herein adapts itself to a change in the means for securing further results now to be explained.

-In one of the standards 8 is fitted an inwardly projecting stud 15-, Figs. 2, 3, 4 and 5, upon which is rotatably mounted a cam 15 carrying on one side a pinion 16, whiclr -meshes with the spacing ratchet 2 of the platen 1. A yoke 17 embraces the cam 15, and the head 17 of the yoke ils pivotally `mounted uponthe shaft 4. so that -the yoke may rock. In the yoke head 17 are made two sockets 18, Fig. 7, spaced apart by a distance in kdegree of arc equal tothat'between the limits of movement ofthe crank member 6. The cra-nk member 6 is formed with an extension' 6/,in which is made a socket containing a spring 19 anda lock-Y ing ball 20, which latter is pressed by the spring into the sockets 18 of the yoke head 17. Figs. 5 and 7. The effect of this arrangement is two-fold. One is that it effectively holds the ribbon in or out of its .final functional position,1by releasably locking the crank member 6 atthe limits of its arc of oscillation. The' otheris that itprovide's for the automatic change ofposi'- `tion of the ribbon when in functional place with respect toits width, at each line-spacing of the platen. When the platen is line- 'spaced, its ratchet 2 engaging the pinion 16 causes` the cani/15 to moveth'e yoke 17.

'Since the yoke is connected with,y the shaft 4. through the spring pressed ball 20 of the crank extension 6, the ,crank is itself llo i to carry moved with the effect of slightly moving the rod T and thus changing the position of the ribbon with respect to its width. According to the contour of the cam,'the yoke may be successively moved in one direction a number of times, as indicated in Fig. 8, and then moved backagain, thus presenting the ribbon to the l'blows of practically its entire width. At the fs'ame time, the spring-pressed ball connection is not such as will prevent the manual manipulation of the shaft 4to swing the crank the ribbon into and out offlinetional position.` The object in leavingr a space between the end of' one tooth section,

` say 14 of the arm operating pinion and the said ribbon 10 down'through anv arc terminin Fig.

lbeginning of ythe next, say,14:,`is to pre-v vent the tooth segment 11 of the arm not wanted, say arm 9,from` reaching engagement with its own tooth section 14 of the pinion during the bodily movement of the rod 7 due to the throw of the crank-member, when moving the ribbon of arm 9 down to its final position. Thus no ribbon is affected until its predecessor has been fully adjusted.

' A brief rsum of the operation will now give a more complete understanding of the present invention. When out ofr use, all the ribbons are elevated as shown in Figs. 1, 2 and 9. If but one is required for use, say the foremost ribbon 10, the thumb wheel13 is turned clock-wise, through a part-revolution. This, through the shaft 12, the tooth section 14 of the mutilated pinionand the tooth-segment 11 klof the arm 9 will swing ating in the position shown inFig. 10. AThen the thumb-wheel 5- is turned partly to throw the crank-member 6 forwardly anddown-A wardly, thereby carrying the nrod 7 down and moving the ribbon 10 down to final position, as in Fig. 11. In this final movement `the spring pressed ball 2O moves from the upper lock-ing socket 18 tothe lower Socket, as 7, and holds the parts with sufficient firmness.v If'two ribbons are wanted, the thumb-wheel-l is turned through two arcs of its revolution, with the effect of carrying down two ribbons to their first position, and then the throw of the crank member 6 will cause both to reach and be locked in functional position. So, too, withthree or more ribbons., as.inv Fig. 12- Meanwhile, when the ribbons are in-use, their position laterally will be changed-ateach line spacing of the platen, through the camand yoke connection.
