COPY-"HOLDER FOR TYPE-"WRITERS- Specification of Letters Patent.

Patented Oct. 24, 1905.

To (itZZ ZUhOTIl/ it may concern:

Be itknown that 1, W ILLIAM H. STEVENS, a citizen of the United States, residing at Greenwood, in the county of Lei-lore and State of Mississippi, have invented new and useful Improvements in Copy-Holders for Typel/Vriters, of which the following is a specification.

This invention relates to improvements in copy-holders for type-writers, and is more especially adapted for use upon a book typewriter, although it is applicable to any other form of type-writer.

One' of the objects of the present invention is to provide a copy or sheet holding and feeding means with an extensible or telescoping frame which permits the copy to be projected over or in the rear of the type-writer, so as to locate the copy-line at the level of the eye or in a convenient position for the operator.

A further object resides in the means for supporting the extensible frame and the copyholding rolls on a type-writer so as to cause both to move bodily with the machine, which, as is well understood, moves transversely and longitudinally of the sheet or book, and thus Further objects and advantages will appear as the nature of the invention is better understood, reference being had to the following description and accompanying drawings, which illustrateione example of my invention.

In the drawings, Figure 1 is a perspective View of my improved copy-holder mounted on the frame of a book type-writing machine. Fig. 2 is a vertical longitudinal section through one of the telescoping members of the extensible frame and also through the copy-holding device, and Fig. 3 is a transverse section on the line a; m of Fig. 2.

Making renewed reference to the drawings,

1 designates a movable carriage of a book type-writer, and 2 the frame on which it slides. This carriage is composed of the cross-bars 3 1 and the end pieces 5 6, which constitute a rectangular frame within which is mounted a suitable supporting-frame 7, on which the type-writer 8 is positioned. As is well known in this class of type-writers, the frame constituted by the bars 3', l, 5, and 6 moves longitudinally of the frame 2 or back and forth toward and away from the operator, while the carriage of the machine slid es transversely on the frame 7, and thus the carriage may be brought into any position above the book, and all of these parts are of the usual construction.

My improved copy-holder is clamped to the rear cross-bar 4: by means of a clamp 9, having a set-screw 10. Secured in the clamp and extending upwardly and rearwardly are standards 11, the upper ends of which are connected by a cross-bar 12. Rigidly secured at each end of this cross-bar are guides 13, which constitute one member of the extensible frame and which has its side edges bent upwardly and inwardly, as at 14, to provide ways in which a flange 15 of a central or intermediate member 16 telescopes. The member 16 is channeled at its side edges to provide the flanges 15 and an upper flange 17 on each side. It is also channeled in its top and bottom faces, as at 18 and 18, to receive a lip 19 on the end of the guide member 13 and to also receive a lip 19 on the end of another guide 20. The

channels or

grooves

18 and 18 of this central or intermediate member 16 terminate short of the ends thereof to provide steps 21 and 21, which limit its movement in the guides 13 and 20, as shown in Fig. 2. The guides 13 and 20 are preferably at their outer ends also provided with

steps

22 and 22, so that when this telescoping frame is collapsed the central or intermediate member 16 will be engaged at its ends by the stops. The sides of the guide 20 are also bent downwardly and inwardly to engage Within the

channels

14 and 15 of the intermediate member, and on its extreme free end is mounted the frame of the copy-holding device.

From the description thus far given it will be seen that the copy-holding device may be projected across and above the type-writer into a position in alinement with the carriage, so that the operator can glance at the copy and at the keys at the same time, and when the type-writer, with the copy-holder, is moved down to near the bottom of the book or sheet the copy may be pushed rearwardly of the type-writer to prevent obstructing the view and to bring the copy into a more desirable position for view.

23 designates a U-shaped frame secured to the free end of the guide 20, and in the ends of this frame is mounted an arbor for the feed-roller 2a, the periphery of which is cov ered with rubber, felt, or other suitable material sufiicient to grip the paper. Secured to the frame 23 beneath the roller is a shield 25, which at its front edge extends into close proximity with the periphery of the roller 24;, as indicated at 26, and serves the purpose of a marker, inasmuch as it stands in a straight line parallel with the axis of the roller. The rear of this shield is bent upwardly and rearwardly, as at 27, and is provided with a plurality of slots 28, through which the pressurerollers 29 project. These pressure-rollers are mounted on a suitable shaft or bar 30, which is engaged by a pair of springs 31, supported on the frame 23 and which serve to hold the pressure-rollers into intimate contact with the periphery of the feed-roller or, when the paper is inserted, to hold it against the feedroller and prevent it from slipping therearound. This shaft or bar 30 terminates at its ends in flattened portions which project forwardly, as at 32, and terminate at each end in a thumb-piece 33. These forward extensions are also provided with slots 3 f, through which the arbor of the feed-roller projects, the extensions being interposed between the ends of the frame 28 and a knob or button 35, which is fast on the arbor and which serves to turn the feed-roller to adjust the copy. Byvirtue of the arrangement of the thumb-pieces 33 on the extensions of the shaft 30, which, as will be seen from the drawings, is at a point adjacent to the knobs 35, the pressure-rollers 29 may be released from engagement with the paper or feed roller with the turning of the knob for the adjustment of the paper, and this in one operation. The copy is inserted between the feed-roller and the pressure-rollers, and by turning the button 35 the roller 24: will feed the paper around until it emerges from beneath the marker 26, as is shown at (r in dotted lines in Fig. 2, and the papers will be prevented from slipping by the yielding engagement of the pressure-rollers 29 with the feed-roller.

It is to be understood that although I have described my invention in detail 1 do not limit myself to the exact construction shown in the drawings, as various changes in the form, proportion, and minor details may be made Without departing from the principle or sacrificing any. of the advantages of my invention.

hat is claimed is 1. The combination with the movable frame of a book type-writer and a copy-holder, of a pair of standards clamped to said frame and movable therewith, a telescoping support for the copy-holder rigidly fixed to said standards, said support including a plurality of interlocked members slidable one within the other with the end members provided with stops at their ends to prevent separation of the members.

2. The combination with the movable frame of a book type-writer, of a copy-holder support secured thereto and including a plurality of telescoping members, a U-shaped frame mounted on one of said members, a feedroller having its arbor journaled in the ends of said frame, a shield secured to said frame, partially inclosing the feed-roller with its front edge terminating in close proximity thereto to constitute a marker and provided with slots in the rear thereof, and pressurerollers yieldingly mounted on the frame and normally projecting through the slots of the shield to grip the paper, substantially as specified.

3. The combination with the movable frame of a book type-writer and the copy-holder therefor, of a support for the copy-holder secured to the said frame and comprising the intermediate channeled member and end members slidably interlocked with said channel member, and means to prevent the separation of said members and limit the movement thereof.

4:. The combination with the movable parts of a book type-writer, of a pair of standards secured to said movable parts, a telescoping support secured to said standards, a copyholder frame mounted on said support, a feedroller journaled in the frame, and pressurerollers yieldingly engaged with the feed-roller, having means accessible from the front of the feed-roller to release their engagement with the latter.

5. The combination with the telescoping support, of a copy-holding device mounted thereon and comprising a U-shaped frame, a feed-roller having its arbor journaled in the ends of said frame, springs secured to said frame, a shaft engaged by the springs, and pressure-rollers mounted on the shaft and yieldingly held in engagement with the feedroller, said shaft having forward extensions guided on the arbor of the feed-roller, and thumb-pieces on the ends of said extensions, substantially as specified.

In testimony whereof I affix my signature in presence of two subscribing witnesses.

WILLIAM H. STEVENS.
