Application filed July 20, 1922. Serial No. 576,276.

To all whom it may concern:

Be it known that I, ,MALCOLM L. Cossrrr, a citizen of the United States, residing at 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 generally to that class of manifolding 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, and it concerns particularly means for selectively operating the carrying arms whereby one or more of the-manifolding members may be used as required.

The object of my invention is to provide simple and effective selective means for this purpose, and to this end my invention consists in the novel manifolding attachment for typewriters which I shall hereinafter fully describe by reference to the accompanying drawings, in whichig. 1 is a:front elevation, artly in section, of my manifolding attac ment, showing the manifolding members and carrying arms elevated.

Fig. 2 is an end elevation of the same from the left, showing by dotted lines its relation to the platen of a machine.

Fig. 3 is a sectional view enlarged, of

85 one set of carrying arms for the manifolding members, taken on the line IIIIII of Fig. 1, and showing the lockin of the arms.

1 indicates a pair of spaced brackets which are adapted for connection with the typewriter in any suitable manner conformably to the particular machine to which the manifolding attachment is applied. As such connection or mounting forms no part of my present invention, and is not essential in the present condition and knowledge of the art, to a full understanding of the device for which I seek a atent, I have not deemed it necessary to il ustrate it, since it would assume various forms according to the particular machine with which the device is used. But in Fig. 2 I have illustrated by the dotted lines, the platen 2 of a typewriter, in order to show the positional relation of the device, adapting its manifolding members to be moved into and out of their functional position in the line of type impact, which line, for the sake of simple illustration is here shown, in said Fig. 2, as on the top of the laten, though it is to be understood that t e position of this line and the relation of the device thereto will vary. in different machines.

In and between the spaced brackets 1 is carried a shaft 3, adapted for rotation, a knob 4 being provided for turning it, as seen in Fig. 1, the body of said shaft, be-

, tween the brackets being preferabl covered by a sleeve '5 which forms at its en s a guide and stop for the arm operating member presently to be described.

Upon each end of the rotatable shaft 3 is pivoted an assembly or set of carrying arms for the manifolding members. In each set I have here shown, for illustration three arms 6,7 and 8, lying one upon the other in nested relation, each arm being independently pivoted on the shaft and each adapted to be independently moved from the elevated position shown by the full lines in-Fig. 2, to a depressed position shown by the dotted lines in said Fig. 2. Between the respective arms of each pair is stretched a .manifoldin member, in the shape of a ribbon 9, whic member is indicated in Fig. 1 by the dotted lines.

i The arm 6 is the first or innermost arm,

' and. as shown in Fig. 6, the base of this arm is provided with a laterally pro ecting lug 6'. The arm 7 is the second or middle arm, and as shown imFig. 7, it is Prl'OVlded with a laterally projecting lug 7 he, arm

8 is the third or outermost arm, and as seen in Fig. 8, itis provided with a laterally projecting lug 8. The lugs 6, 7' and 8', as seen in these fi res, and especially in Fig.

- 13 have successively decreasing lengths, and

15 are so positioned with relation to each other, that when the arms are assembled, the lugs lie one behind the other, the longest being in front, and they project in a line parallel -with the rod, to successively decreasing distances, asseen in Fig. 13.

Upon the shaft 3, near each end is fitted the arm operating member 10, adapted to both turn with and to slide upon the shaft This member, as shown in Figs. 1, 4, 5 and 12, is slotted over a cross pin 11 of the shaft, whereby it rotates with said shaft and can slide linearly therein for which latter movement it is formed with a tubular shank 10' slidable on the shaft and within the sleeve 5 of said shaft, as seen in the sectional part of Fig. 1. A spring 12, Fig. 1, normally presses and yieldingly holds the operative member 10 out to its work.

The face of the operating member 10 1s v formed on one side with a double cam surface 13, Figs. .4 and 5, in the apex of which is a pick-up shoulder 14; and said face, opposite same cam surface has also an arm-returning lug 15, as shown in Fig. 4.

The operation of the device, as far as described, is as follows: In the normal, out of use osition of the parts, as shown in Fig 1, t e arms are elevated, and the armreturning lug 15 of the operating member 1O lies immediately in front of the longest lug 6', which is the lug of the innermost arm.

If. now, the shaft 3 be'turned forwardly as viewed in Fig. 1, that is counter clockwise, by its knob 4, it will rotate the operating member 10 forwardly until the firstincline ofthe face cam 13 of said member,

reaching and sliding upon the ends of the length-graduated lugs 6, 7' and 8 of the 1 arms 6, 7 and 8, will cause said member to be forced linearly along the shaft, against the controlling spring 12. This linear movement of the member 10 will enable the pick-up shoulder 14 of said member to move 00 freely past the shorter lugs 8' and 7' of the arms 8 and 7 without affecting said arms,

I but as the extremity of the first section of the cam is reached and it ceases} to function, the operating member will spring .for-

J 66 ward and said shoulder 14 will engage behind the long lug 6 of the arm 6, as seen in Fig. 13, and thereupon, continued rotation of the operating member 10 will pickup said long lug 6 and will thus depress the 6 to the position shown by the dotted lines in Fig. 2 and carry the first manifolding ribbon down to the line of type impact,

the other arms? and 8 remaining elevated.

If-a second manifolding'ribbon is required, the shaft 3 is turned in a reverse direction, and the shoulder 14 moves-away from the depressed long lug 6'.' The now retreating first section of the cam 13 riding on said lug allows the operating member to slide forward along the shaft, and this move ment carries the opposite, advancing side or section of the cam into contact with the elevated lugs 7' and 8. Riding on these lugs the operating member is then again slid back along the shaft, until the pick-up shoulder 14 drops in behind the second length lug 7 Then a forward rotation of the shaft causes the second arm 7 to be depressed. Finally another reversal of the shaft will cause the operating member 10 to return and pick up the short lug 8 of the third arm, and a forward movement of the shaft will then depress said arm. To return the arms, the shaft 3 is reversed far enough to cause its lug 15 to rise up under the depressed. longest lug 6', and continued reverse movement will return all the lugs, arms and ribbons to their initial elevated position.

In order to y ieldingly or releasably lock the arms, so that they may be neither inadvertently moved nor have any tendency, due to frictional juxtaposition to so move when any one is intentionally operated, the arms, as shown in Figs. 6, 7 and 8, are provided at their bases with. the springy tongues 16 relatively so positioned in the several bases, asto not interfere with the nesting of the arms. These tongues yieldingly, en-

gage a notch 17-Fig. 3, in the bracket bearings 18 of the shaft 3.

he relative posltions of these lockingparts may be reversed, as shown in Figs. 9, 10

and 11, wherein the spring tongues 16 are carried by the brackets 1, and the notches 17 are in the base of the arms.
