This invention relates to manifolding means for typewriters.

An object of the invention is to provide typewriter attachment means performing the function but eliminating the use of the'commonly utilized carbon paper. Another object is to attachable to the most generally used forms or makes of typewriter without alteration of the machines. t i Another object to produce means of this kind adapted to produce superior results at a lessenedcost. Y

Another object is to provide an improved holding means for an ink transfer ribbon or the like.

"Another object is to provide manifolding means which are simple in manufacture and in use.

These and other objects are attained by the means described hereinand illustrated in the accompanying drawings, in which:

Fig. 1 is a front elevational view of a typewriter platen and carriage with means of the present invention associated therewith, parts be- 8 qk n'aw T Fig. 2 is a top plan view of the same.

Fig. 3 is a cross sectional view taken on line 3- 3 of Fig. 1. f e W Fig.5 is a diagrammatic end view of a platen with sheets. of paper, holding means therefor, and ink transfer ribbons of this invention associated th r w h r 4 j Eigs 5 00.9 inclusive aredetail views of parts of, the present invention. H

t The partsof atypewriter illustrated, with which the means of this invention are adapted to be associated,-comprise theplaten l2 mounted upon ashaft I3 betweenthe'sides l4 and 15 of a platen carriage, the platen being rotatable by means of athumb wheel l6. I i

The manifolding means of this invention comprise a bracket I1 adapted to be readily posi tioned upon one-of the sides l5 of the platen carriage by the screws normally provided thereon.

As illustrated, the bracket is adapted to be positioned on the outside face of carriage side l5 by means of screws l8 passing through perforations 19 (Fig. 6) into the carriage. In addition, the

bracket here shown is provided with a large perforation 20 through which. the end of the platenshaft I3 is adapted to pass. Any other attachment means may be utilized. Moreover, in some makes of typewriter, it may be more desirable to mount the bracket on the top rather thanon the side face of the carriage side. The

provide such means readily shape of the bracket may be modified to meet such requirements.

Bracket 11, at its outer end is provided with an ear 2! extendinginwardly of the carriage and parallel with the platen. Strip-like bars 22 are pivotally connected by means of extensions 24 to said ear, as at 23, for pivotal movement in a verticalplane. Bars 22 may be of angle-strip shape, that is of L-shape cross section to permit nesting of the bars one upon the other. These bars are adapted in operative position, to extend across to the opposite side ll of the platen carriage, forwardly of and in spaced relationship with the .platen.- At their free ends bars 22 may benotched, as at 25; (Fig. 5) to be readily engaged'by a spring clip 26 vertically mounted as at'28(Fig'. 3) on a finger 29 which in turn is secured upon a lug 30 attached to side ll of the carriage. Clip 26 is provided with notches 21 adapted one each to receive one of said free ends of the bars. "Ihe'clip is resiliently retained in engagement with the bar ends by means of a spring 3 I. Anyother suitable means for holding the free ends of bars 22 may be utilized.

Each bar 22has at each end thereof an arm '32 and 33. Arms: may be integral-with bar 22,

as shown. Arm 32 is a separate member formed at one end with a sleeve 34 adapted to slidably embrace bar 22- (Fig. 3). 'The outer portions of said arms are turned downwardly as at 35 and their freeends are formed into spindles 36.

Spindles 36; are each adapted to holdan end of an ink transferribbon 31. ,By slidable movementor arm 32 along its bar, the ribbon can be rendered taut for use or loosened for removal. A shifting'tab 40 may be provided on the bottom of sleeve 34. In operative condition, the ribbon is adapted to extend adjacent the platen in upright position as to its width and in the line of the type strokes of the typewriter. In order thata plurality of the manifolding ribbons may be utilized, the distances between the

arms

32 and 33 of each pair are progressively diminished whereby one pair is embraced by the next pair. And in order that the ribbons 31 may be operatively positioned one behind the other, the-pairs of

arms

32 and 33 are progressively diminished in length. The foregoing structure is clearly seen in Fig. 3.

It will further be seen that the adjacently disposed

arms

32 and 33 rest one upon the other. In orderto support the outermost pair of arms, the lug 30 extends outwardly, as at (Fig. 2) beneath the arm at that side, and at the other side, the outermost arm is adapted ,to rest upon a stud 39 (Figs. 2 and 6) struck from the body of bracket H, or upon some similar support means.

The bars 22 are adapted to be pivotally moved into operative position through a vertical plane extending transversely of the typewriter. At this time, the sheets M (Fig. 4) placed in a typewriter are adapted to be held apart to permit entry of a ribbon between each pair of sheets. Each ribbon is then in position to transfer typed impressions from the outer to the inner of two sheets. When it is desired to remove the ribbons from operative position, the bars 22 are swung outwardly of the carriage side l5 and are there adapted to be disposed against a support strip 42 (Figs. I

1 and 2) having guides 43 thereon.

A modified bar structure is seen-in Fig. v'7. Herein a separate pivot plate 45 is substituted for the integral bar extension 24 seen in Fig. 5. Plate 35 is adapted to be pivotally mounted on ear 2! and is provided with a pair of adjacently disposed resilient flanges 5! adapted to slidably receive between them and resiliently hold the end portion 52 of bar 44%. End portion 52 is, formed with an aperture ib adapted to receive the resiliently contacting studs 41 provided on flanges. 5i whereby the bar may be snapped into operative position. By this means, bars 44 maybe instantaneously placed in and removed from operative association with pivot plate i5. It will be understood that a desirable number of said pivot plates may be pivotally mounted on the same axis on ear 2i, in overlying relationship one with another. I

In Fig. 8, the ribbon 37 instead ofbeing simply looped at its ends, as in Fig. 5, is there provided with a clip 48, adapted to have one end portion 39 doubled upon an end of the ribbon, and another bent portion 50 jslightly spaced'from the ribbon to permit insertion of the holding spindle 36. 1

It is obvious that the operation is simple and that one or a plurality of the ribbons may be utilized in accordance with manifolding requirements. The resulting typed impressions are strong and clear; One of the ribbons is adapted to long outlast a sheet of carbon paper.
