MANIFOLDING ATTACHMENT FOR TYPEWRITJERS.

Application filed June so, 1922. Serial at. 569,612.

To all whom it may concern left hand end, F

ig- 1, is pivoted a bearing W Be it known that I, MALooLM L. Cosslr'r,\member a controlled by a spring 5. In the 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 whlchthe following is a specification.

M invention relates to that class of mani- W foldlng attachments for typewriters and the like, in which one or more manifolding members are carried by arms mounted on the platen carriage of the machine and are adapted, by the movement of said arms, to W be placed in and removed from functional position in the line of type impact; and more especially it relates to a form of such attachments in which the manifolding members are stored within a chambered member as and are adapted to be drawn therefrom in successive lengths for association with-the carrying arms.

In certain forms of these attachments the carrying arms are associated with a pluat rality of independently rotatable nested sleeves, and one of the objects of my present invention is to constitute these nested sleeves the chambered member for storing the manifolding members. Another object of my invention is to pro- I vide simple and effective means for placing and holding the manifolding members in proper tension.

Still another object is to provide simple and effective means for the selective operation of the carrying arms whereby one or more of the'manifolding members may be moved into and out of functional position. With these and other objects in view, my invention consists in the novel manifolding attachment for typewriters which I shall now fully describe, by reference to the accompanying drawings, in which-- Fig. 1 is a left hand end elevation of my attachment.

Fig. 2 is a right hand end elevation of the same.

Fig. 3 is a of Fig. 1.

1 is the platen carriage of a typewriter, and 2 is the platen. Secured upon the platen carriage, one near each end, are the bracket arms 3. I To the free extremity of the bracket arm 3, at the partial section on the line 3- 3 bers of said series being indicated by 12' and 12" respectively.

free extremity of this bearing member is fitted a threaded centering shaft 6, set by a screw 7, Fig. 1. In the right hand bracket arm 3 is fitted a threaded centering shaft 8, Figs. 2 and 3, having a knob 9 for turning it-Fig. 3. J I

Referring now particularly to Fig. 3, there is fitted to the left hand end centerin shaft 6 a housing casing 10, the inner end of the casing being centered upon an abutment member 11 which is carried by the innermost sleeve 12 of a nested series of independently rotatable sleeves, the other mem- The right hand centering shaft 8 is fitted through centering abutments 13 carried by the innermost sleeve 12.

Each sleeve of the nested series hasat each end a carrying arm. The arms of the innermost sleeve are designated by 14, those of the middle sleeve by 14and those of the outer sleeve by 14". The arms at each end lie in superposed nested relation, and the free extremity of each arm has pivoted to it a ribbon carrying clip-tongue 15, Fig. 1.

Within the housing casing 10 are the spools 16 adapted for independent rotation. These spools carry the manifolding members 17, here shown as ribbons. The ribbons pass from the spools outwardly through suitable slots 18, in the housing casing 10, and are directed within the innermost sleeve to their respective arms at the left hand end. Turning about the bases of these arms the ribbons extend along them to and over the clip-tongues 15 of the arms and thence extend to and are engaged by the clips of the respective arms at the right hand end. The W extension of the ribbons between the arms is omitted in Fig. 3, as said arms are shown therein broken. In order to hold the ribbons against pulling strain when under tension, as will be presently described, there is on the face'of each left hand arm, as is 'of a springy nature, secured to the centering sleeves playing in slots in the inner sleeves,

and all extending into the path of revolution of the pick-up arm 21 onthe shaft 8.

The operation of the device is as follows:

\Vhen out of use, all the arms are elevated, and the required sections of manifolding ribbons are drawn out from their chambered spools 16 housed within the nested sleeves, and extend between and are carried by their respective pairs of arms.

When the use of say one ribbon is required, namely, that carried by the foremost arms 14 of the outer sleeve 12", the centering shaft 8 is turned by its knob 9, so that its pick-up arm 21 acting on the first sleeve stud 22 will rotate said sleeve and thus carry the pair of arms 14" of said sleeve and the ribbon extending between them, down to the position shown by the upper dotted lines in Figs. 1 and 2. In this position the ribbon carrying clip tongues 15 contact with and rest upon the platen 2. Further movement, to carry the ribbon down to functional position in the line of type impact, as shown by the lower dotted lines in Figs. 1 and 2, causes the clip tongues sliding upon the platen, to swing outwardly, which movement, by drawing on the length of ribbon section extending along the face of the left hand arm, Fig. 1, has the effect of tightening the ribbon and placing the entire length of functional section between the pair of arms, under proper tension for use.

It will be seen that this tensioning movement is properly resisted by the frictional pressure on the ribbon of the fiat spring 20, so that the ribbon spool does not yield to the tension.

If a second ribbon is required, the shaft 8, which, by its previous rotation, in its threaded fitting has moved inwardly far enough to cause its pick up arm to contact with the stud 22 of the second sleeve 12, will now, by its further rotation, swing said sleeve with its arms and ribbon down, as before described, and, likewise, with the third sleeve and its associated parts.

As each section of the ribbons is used up, the end of the ribbon is detached from the clip tongues, and a fresh section is drawn out from the storing spool and placed in position between the arms.
