COPY-HOLDER.

SPECIFICATION forming part of Letters Patent No. 229,001, dated June 22, 1880.

Application filed March 22, 1880.

To all whom it may concern:

Be it known that I, JOHN LAW, of Forest City, in the. county of Winnebago and State of Iowa, have invented a new and useful Improvement in Copy-Holders 5 and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to copy-holders of that class in which the paper tobc copied is fed between two rollers, for the purpose of holding the copy and presenting in proper order to the copyist the written or printed matter which is to be copied.

It consists of an improved device for holdin g the upper roller down upon the paper, and, in connection therewith, of an improved device for steadying the paper and for indicating to the copyist the particular part of the work upon which he is engaged.

The accompanying drawings illustrate my invention, and show one convenient form by which it may be mounted and fitted for use.

Figure 1 shows a perspective view of my invention with the paper in place. Fig. 2 is a front view of the apparatus without the paper, and with the drop or guide bar elevated.

In these drawings, a b are rollers, of a length fitted to receive paper of ordinarywidth, or of any width desired. These rollers are provided with rubber bands, the lower preferably cylindrical and the upper preferably turned down so as to leave distinct wheels or rollers l 1 1 1, on which the rubber bands are placed, and which correspond in location to the bands upon the lower wheels. These rollers turn freely in their bearings in the sides of the frame. The bearings of the upper roller, however, are in slots which allow the said roller slight vertical motion and permit it to rest upon the periphery of the lower roller. Each of these rollers, or the bearing-surface thereof, should be made of exactly the same circumference throughout their entire length, in order to hold the paper accurately as it passes through between them.

Instead of rubber bands, the rollers may be covered with cloth or any other suitable ma- (No model.)

terial which will hold the paper firmly, preventing it from slipping.

The pivots of the upper roller extend beyond the sides, as shown at c, and leave ex posed necks, on which rest grooved arms d d, pivoted to the frame just behind the said pivots 00. These arms are provided with acrossbar, 0, which, when brought forward into position, lies over a second cross-bar, f, but is so arranged in relation to the latter bar as to permit the arms d d to bear upon the pivots of the upper roller when the bar 0 is dropped, thus pressing the upper roller down upon the paper. The paper passes from the rear between the rollers, and is held down upon the crossbar f by the bar 6, which latter serves the purpose of holdingthe paper in place after it has passed the roller, as well as to press by its weight upon the arms (1, which act as levers to press down the upper roller. The

bar 6 also serves as a mark to guide the eye of the copyist upon the paper from which the copy is made. This last function of the bar is a very useful one, enabling the copyist to read with ease and accuracy, and saving valuable time, and at the same time enabling the copyist to catch the desired word with certainty, and to avoid danger of omissions or repetitions.

The frame may be made of wood or metal, and the form of it may be varied as taste or fancy may dictate.

That part of the frame below the rollers may be omitted and the rollers supported by an arm in the rear, which arm may be fastened by a clamp, or'in any convenient way, to a type-case when the apparatus. is designed for the use of a compositor. In this case the knob h on the lower roller, by which it is turned, should be changed to the other end.

I am aware that copy-holders having rollers for holding the paper to be copied in place are not new; but

What I claim as my .invention is- 1. The combination, with a fixed lower roller and an adjustable upper roller, of the pivoted arm 01, adapted to bear upon said upper roller,

and the plate 0, substantially as described and shown.

2. In combination with the rollers, and with the arms d and cross-bar e, the fixed barf, as

5 and for the purpose set forth.

3. Acopy-holder consisting of a fixed roller, an upper roller journaled in slots and having extended journals, pivoted levers d, bearing on such extended journals, a clamping-plate,

e, and a fixed cross-bar, f, all constructed and 10 arranged as set forth.

in testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
