COPY-HOLDER FOR TYPE-WRlTERS.

EPECIFICATION forming part of Letters Patent No. 336,551, dated February 23, 1886.

Application filed March 7, 1885. Serial No. 153,070. (No model.)

To (tZZ whom it may concern:

Be it known that I, 'WILLIAM H. CLARK- soN, a citizen of the United States, residing in New York, in the county and State of New York, have invented certain new and useful Improvements in Copy-Holders for T vpe-lVriting Machines Combined; and I hereby declare that the following is a full, clear, and exact description of the same, such as will enable any one skilled in the art to which it appertains to make and use my invention, reference being had to the accompanying drawings, forming a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings represents a side elevation of a copy holder and type writing machine combined embodying my improvements. Fig. 2 is a front view of the same. Fig. 3 is a section through the footrests, taken on the line at x in Fig. 1. Fig. 4 is a detail front view of the manner of attaching the copy-holder to the framing of the type-writing machine. Fig. 5 is a detail sectional view of one of the thimble-brackets, taken on the line yy in Fig. 1. Fig. 6 is a modification in the manner of attaching the driving pulleys to the framing of the machine.

My invention relates to improvements in the means by which copy-holders are combined with type-writing machines; and it consists in the detailed construction of the parts hereinafter fully described, whereby the copy-h older is combined with the type-writing machine in an improved manner, and may be worked either by foot or by hand, as most convenient.

I will now proceed to describe my invention with reference to the accompanying drawings,

in which similar letters of reference where used in the different figures indicate corresponding parts.

A is the framing of a type-writing machine; B, the table on which it stands.

0 is the copy-holder, supported by the side frames, 0, attached to the lugs a at the upper back part of the framing A by the pins 0, which pass through corresponding holes in frames 0 and lugs a and allow the said side frames, 0, to turn freely.

c is a catch or pawl attached to the side frame, 0, which engages with the grooves a on lug a and supports the copy-holder at any desired elevation.

p is a small pin or stop projecting from the side of lug a to prevent the copy-holder from falling too far forward. hen not required, the copy-holder can be lowered down behind the machine, as shown by the dotted lines in Fig. 1.

The copy-holder may consist of various combinations of rollers. I prefer to use the forms shown and described in my applications for Letters Patent filed January 3, 1884, Serial No. 118,472, and June 11, 1884:, Serial No. 134,577; but in place of the knobs described for rotating the main cylinder I attach grooved pulleys c to the shaft of the said main cylin der, so that it may be rotated by a driving belt or cord, aswell as by hand, di rectlyl Two grooved pulleys coupled together, 02 and (1', run on a pin, d, at the back part ofthe machine, of which that marked (1 drives the pulley c by the belt D, while that marked d is driven by a similar grooved pulley, e, which runs on a pin, e, at the front partof the ma chine by means of the beltE. The pins (1 and 6' may be secured directly to the framing of the machine, as shown in Fig. 6, by means of the flange F and screws or rivets f,- but I generally prefer to secure them by means of the brackets G, to which the said pinsarc attached.

Each bracket G is provided with a tapering thimble, g, which fits over the rubber foot on the machine, and is held there by the thumbscrew 9. Two other thumb-screws g pass through the bracket and screw into the side of the framing. The end of the bracket is bent down, forming a flat hook, 9 which passes under the framing, and also assists in 35 r in Fig. 4, in which the catch is placed on loose thimbles, similar to those marked but without any bracket, and these I slip over the feet on the other side of the machine and secure them with thumb-screws.

I is a bar fixed between the legs I) of the table B, near the ground on which they rest. It is provided with collars 2', sliding upon it, and secured by the thumb-scews 11.

J is a sleeve which turns loosely on the bar I, between the collars d.

K is a pin-wheel, fastened on sleeve J, and provided with a series of pins, k, projecting from the sides of it and spaced alternately at equal distances.

L is a grooved pulley, also screwed on sleeve J, and provided with a belt, 1, connecting it with the pulley c on the end of the main cylinder-shaft of the copy-holder.

M are footrests journaled loosely upon sleeve J on either side of the pin-wheel. The circumferences of these foot-rests may be made smooth; but by preference I form ribs m upon them to prevent the feet from slipping; I also chamber out the inside to lessen the friction between them and sleeve J.

"I sometimes prefer to make the pin-wheel K with a groove, it, upon its outer circumference, and let it drive the pulley c on the copy-holder direct. In this case pulley L and sleeve J are not required, as both the foot-rest and the pin-wheel then run loose upon the bar I, between the collars i.

I generally prefer to make the catch or pawl by which the exact position of the copy-holder is regulated to work with a spring, as shown the inside of the side frame, 0, which has lugs c and 0 upon it for keeping said catch in position.

n is a collar, secured on the catch by a screw or pin, a. A spring, 0, is arranged between the collar n and lug The end of the catch is bent round to form a handle, a, on the outside of the frame, so that it may be raised conveniently against the downward pressure of the spring, which otherwise keeps it in one of the grooves in lug a.

In using the foot-gear to turn the copy-holder, the operator places his feet upon the footrests and presses upon the pins which project from the sides of the pin-wheel with the sole or heel of one of his shoes, according to the direction in which he wishes to rotate the cylinder of the copy-holder.

It will be seen that instead of the pulley c on the copy-holder being driven direct from a pulley on the bar I it might have been driven through intermediate pulleys attached to the frame A in a similar manner to the pulleys d, d, or c.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination of a-copy-holder provided with holes in the lower part of its framing,a type-writing machineprovided with corresponding holes in the upper back part of its framing, pins passing through the said holes, so that the said copy-holder may turn freely, and a catch for holding the said copy-holder at any desired elevation, substantially as described and shown, and for the purpose set forth.

2. The combination of a copy-holder, a type-writing machine, pins for pivoting the framing of the copy-holder to the framing of the type-writing machine, a spring-catch for holding the copy-holder at any desired elevation, driving-pulleys secured upon the main cylinder-shaft of the copy-holder, and the means for rotating the said driving-pulleys, substantially as described and shown, and for the purpose set forth.

3. The combination of a copy-holder provided with driving-pulleys upon the ends of its main cylinder-shaft, and with holes in the lower part of its framing, a type-writing machine provided with corresponding holes in the lower part of its framing, pins passing through said holes, so that said copy-holder may turn freely, a catch for holding said copy-holder at any desired elevation, a table having legs and provided with a cross-bar near the ground, and with a driving-pulley and pinwheel journaled upon said cross-bar, so that the copy-holder cylinder may be revolved by the feet of the operator, substantially as described and shown.

4:. The combination of the copy-holder C,

provided with driving-pulleys c and holes in the lower part of itsframing c, a type-writing machine provided with corresponding holes in the upper back part of its framing, pins 0, passing through said holes, a catch for holding the said copy-holder at any desired elevation, table B, having legs b, bar I, provided with collars t, sleeve J, pin-wheel K, having pins 7c, driving-pulley L, and foot-rests M, substautially as described and shown, and for the purpose set forth.

' 5. The combination of the copy-holder 0, provided with driving-pulleys c and holes in the lower parts of its frames 0, a type-writing machine provided with corresponding holes in the upper back part of its framing, pins 0, passing through said holes, a catch for holding the said copy-holder at any desired elevation, grooved pulleys for rotating the drivingpulleys c and brackets G, provided with pins for carrying the said grooved pulleys, and with thimbles g, thumb-screws g, and fiat hooks 9 substantially as described and shown, and for the purpose set forth.
