MANIFOLDING ATTACHMENT 'FGR T'YPEWRITEBS.
Application filed August 21, 1923. Serial No. 658,%0.
To all whom it may concern: I
Be it known that I, MALCOLM L. Cossrrr, a citizen of the United States, residing at Oakland, 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.
M invention relates to that class of mani- 1 folding attachments for' typewriters in which a plurality of manifolding members are carried by movable arms mounted on the machine and are adapted, to be placed in and removed from functional position in the line of type impact.
One of the objects of my invention is to provide simple and effective means for selectively operating the carrying arms whereby one or more of the manifolding members may be used as required.
Another object is to provide means for adjusting the position of the paper-holding fingers to avoid interference with the manifolding members when the latter are being moved to functional position. Other objects are to improve the mounting of the movable arms, to provide simple means for holding said arms at the limits of their movement both in and out of position, and
to provide for oscillating the manifolding members when in functional position, to utilize their full width. To these ends my invention consists in the novel manifolding attachment for ty ewriters which I shall as hereinafter fully escribe by reference to the accompanying drawings, in which Fig. 1 is a front elevation of my manifolding attachment as applied to a typewriter.
Fig. 2 is a plan view partly in horizontal section of the arm-operating selective assembly, taken on the line 2-2 of Fig. 3, said View being from the rear of the attachment at the right; hand of Fig. 1.
Fig. 3'is a part sectional view of the same on the line 3-3 of Fig. 2.

Fig. 17 is a plan view of the left hand end. Fig 18 is a detail showing the sequence of the ribbons with respect to the platen and the record paper sheets. W i Fig. 19 is a view of a means for adjusting automatically the paper-fingers.
1 is a portion of the frame of a typewriter, 2 is the platen-carriage, 3 is the platen, the shaft 4 of which carrles the turning knob 5. e5 6 is the index pointer, 7 is the main inking ribbon, 8 are the paper-fingers at the front of the platen near each end, and 9 in F i 12 is the paper guide apron. These or similar elements are all parts of a ty ical typewriter and are suflicient for a all understanding of my intention. 10 in Figs. 12, 13, and 16, are brackets having angularly directed'feet 10 by which they are secured to a back bar 2 on the platen carriage 2. me There are 2 brackets 10, one at either end of the laten carriage, said brackets rising back of the laten and pa er ide a ron, Figs. 12 and 16. In the rac ets an extending between them is rotatably mounted in is carried a manifolding member 16 here ing their shown as a shortsection of ribbon Figs. 1 and 18. -Upon the rod 11 is rotatably mounted a sleeve 1 1 which has fixed to it near each end an arm 12, between the extremities of which is carried a second manifoldin member or ribbon 13, Figs. 1 and 18. Tie adjacent arms 12 and 15 of each pair lie in nested relation for a portion of" their length, as seen in Figs. 12 and 16, the arms 12 being the innermost.
[he arm 12 at the right hand, viewed from the front of the machine has near the front of its base a laterally projecting lug 12, Fig. 6, and the corresponding arm 15 has at its base near its front a laterally projecting lug 15', Fig. 7. The lug 15' lies back of and is. shorter than the lug 12 the two lugs lying in a circular path having the rod 11 for a center. It will now be seen that if pressure from behind be brought tobear upon the in 12 the pair of arms 12 will be turned with their sleeve 14 about the rod 11 as an axis, from an elevated position back of and above the platen as seen by the dotted lines in Fig. 12 to a depressed position down to and curving over the platen, as shown by the full lines in said Fig. 12, thereby carrymanifolding member 13 down to functional position. in front of the platen in the line of type-impact, between the record paper sheets 43 as in'Fig. 18. Ifthen pressure from behind be exerted upon the lug 15, the pair of arms 15 with their manifoldingmember 16, Fig. 18, will be similarly operated turning with their rod 11 as an axis, said operations being those common to manifoldingattachments of this type. And it will also be seen that if, when said arms are in depressed position. pressure be brought upon the front of the lug 12, tending to lift the arms 12, both sets of arms 12 and 15 will be raised to elevated position, since the'arms 12 underlie the arms 15.
Referring now particularly to Fig. 2, there is mounted rotatably about the projecting end of the rod 11 and within the bearing of the right hand bracket 10 a short sleeve 17 having a turning knob 18 upon its end. Upon this sleeve 17 is slotted and pingnided at 19 an arm-operating member 20,
adapted for turning movement with and reciprocative linear movement on said sleeve, th latter movement being controlled by a spring 21 tending to hold said member projected towards the ribbon carrying arms 12 and 15, as seen in Figs. 2 and 3. In a longitudinal slotin the inner end of the arm-operating member is slidablymounted a pawl 22 the point of which projects into the circular path in which the arm lugs 12' and 15 lie andmove, of the arm-operating member 20 is formed,
Fig. 2. The operative end forward of the awl 22, with a cam incline 20 and this inc ine lies in the path of the spring 21, the arm-operating member 20 is held forward with its cam incline 20 in the path of the longer lug 12 and its slidable pawl 22 in the path of the shorter lug 15' as seen in Figs. 2 and 10. When the short sleeve 17 is turned forward by its knob 18,
the member 20 turns with it. But when the cam incline 20 of said member reaches and contacts with the longer lug 12 said member 20 is thereby linearly forced back, and it carries the pawl 22, which it should be stated is seated with sufficient friction, back with it, so that the point of the pawl misses the short lug. 15', and then engages and picks up the long lug 12 as seen in'Fig. 4; and further rotative movement then carries the first pair of arms 12 down, as heretofore described. See Fig. 9. A reverse turning of the knob 18 then carries the member 20 and its pawl 22 back and said member, under the influence of the spring 21, moves forwardly, the pawl 22 slipping by and engaging behind the short lug 15. Forward turning of the knob 18 now causes the pawl by contact with said short lug 15" to carry down the second pair of arms 15, the member 20 remaining projected since it is free at first, of the coaction of its cam incline 20 and the depressed'long lug 12. But towards the end of this second stroke of the member 20 and before the second pair of arms 15 are fully down, the cam incline 20' of said memher reaches the depressed long lug 12 so that said member begins to move back which would normally have the efi'ect of carrying the pawl 22 back with it away from the short limit. To avoid this is the purpose of the separately controllable pawl 22, the further control features of which are as follows.
Rotatably mounted about the arm-operating member 20 is an outer bearing 23 in which is made an arcuate guide slot 23' the outer wall of which near its lower end is inclined at 23" towards the inner wall. See Figs. 4 and 10. The pawl 22 is provided with a stud 22' which plays in this slot 23' both circularly and linearly. Its normal play is against the inner wall of the slot as in Fig. 10, while its linear play is between the inner and outer walls of said slot. The general width of the slot is such as to provide for the backward movement of the member 20 under the contact of its cam-incline 20' with the long lug 12', but when the stud 22 of the pawl 22 reaches the incline 23" of the outer wall of the guide slot 23' the pawl is stopped from moving back with the member 20 which at the time is thus moving, its cam incline 20 now being in contact with and acted upon by the previously depressed long lug 12. The pawl 22 there fore does not withdraw from its contact with theshort ing but continues to engage it and to depress it to its limit, so that the second pair of arms 15 can be fully depressed. Q
In order to more fully understand the reason for and the function of the separately controllable pawl 22'of the present arm-operating selective member and to point out clearly the novelty herein which novelty rests in said pawl, it may be of advantage to refer to my previous Patent No. 1,452,193,
dated April 17, 1923, which discloses an arm-operating selective mechanism similar in general to the present'mechanism, in that the previous device comprises a linearly movable arm-operating member rotatable in the axis of movement of the arms, and r0- vided with a pick-up shoulder adapt Itlo en s selectively enga e lugs of different I upon the arms,
e selection being contro led by cam lnclines on said member. In that device, however, the pick-up shoulder is integral with said arm-operating member, and, therefore, when, upon the second stroke, said member is incidentally forced back near the limit of the stroke the pickup shoulder tends to withdraw from the shorter arm-lug it is then engaging, with the result. that the second pair of arms do not quite reach their limit of de ression. It will now be seen that this di culty is, by the present invention, overcome, "due to the separately controllable pawl 22 carried by the arm-operating member 20.
To return the arms to'elevated position the member 20 is formed with a shoulder 24, Fig. 5, which rises up under the longer lug 12' of the arm 12.
The outer bearing 23, heretofore referred to is extended at 25, Figs. 2 and 11,. for three purposes. One pu e 1s to provide a longer journal bearing or the ends of the axis members 11 and 14 of the arms 15 and 12, to counteract the torsional strain upon them due to the off-center contact pressure of the pawl '22 on the arm lugs 12' and 15. Another purpose is to carry the yielding locking springs 26 and 27, the former hearing upon flattened places 28 which are 45 d apart, on the rod 11 Fig. 15 and the latter bearing upon flattened places 29 on the sleeve 14, Fig. 14, so that the arms 12 and 15 are yieldably held or locked at their limits of movement. A third purpose is to carry the lever 30, Figs. 2, 11 and 12, for adjusting the manifolding r bbons widthwise when in functional position, at each type impact.
line spacing movement of the platen, so that I i said ribbons may be utilized over practically their entire width, thereby prolonging their life. The lever 30 is secured at one end to the rocking outer bearing 23 and at its other end it is yoked upon a cam 31, Fig. 12 on the platen shaft 4. When the ribbon carrying arms are depressed to functional posir tion, the lockin s rings 26 and 27 being in engagement with t e flattened places 28 and 29 on the axis members 11 and 14 of said arms, frictionally connect-the outer bearing 23 with said members. Then when the platen'is rotated, its shaft cam 31 rocks the lever 30 together with the outer bearing 23; and thus through the springs 26 and 27 which said bearing carries, the axis members 11 and 14 are rocked, which. movement will oscillate the ribbon carrying arms and the ribbons transversely of the, platen. The paper fingers 8 in front of the platen, near each end are as usual yieldably held close to the platen and are slidable to different positions along the length of the platen. On account of their necessary closeness to the platen, it is obvious that some means mustbe provided to temporarily move them away fromthe folding ribbons 13 and 16 to freely pass in between them and the platen, in descendin to their functional position in the line 0 Accordingly I have substi- 'tuted for the usual fixed bar or rod which carries these paper fingers 8 a-rocking bar 32, Figs. 16 and 17, held under rotative tenlaten, in order to allow the manision by a spring 33 at one end. The a er fingers are slidably mounted upon this r and rock with it. One end of the bar 32- has a crank 34, and against this bears a pivoted fingerlever 35, by the eperationi of which, the bar 32 may easily be rocked to carry the paper fingers 8 outwardly away from the platen, as shown by the dotted lines in Fig. 16, while the manifolding ribbons are descending to place. Thereupon the lever 35 being released the bar 32 will rock back, under the infiuence of its spring 33, and carry the pa er-fingers back to functional position. A though this opening of the paper fingers may be performed by manual operation of the finger-lever 35, it may, if found desirable, be efiected automatically throughthe movement of the ribn carrying arm itself. I illustrate such automatic operation in Fig. 19 wherein the upper end of the lever 35 is connected by a lin 36 with one of the ribbon arms 15. The connection of the link and lever is by means of a stud 37 on the link, playing in an elongated slot 38 in the head of the lever, sald slot having an initial socket 39 in which the stud normally bears. It will be seen that as the arm .15 moves forward, the stud 37 bearing on the socket 339 will throw the lever 35 forward and thus rock the paper-finger bar 32. Then when the arm 15 is depressed to its limit and remains there, the link 36 may be manually moved to releasethe engagement of the stud 37 and socket 39, whereupon the lever may travel back with its head slot 38 playing over the stud,- thus allowing the arm 15 to remain depressed While the paper-finger bar 32 rocks back.
In Figs. 1 and 16, are shown the usual ratchet mechanism for turning the platen, comprising the lever 40, the pawl 41 and the ratchet 42.
