COPY-HOLDER FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 372,495, dated November 1, 1887.

(No model.)

To aZ-Z 107mm it may concern:

Be it known that I, JOHN C. SKEL'roN, a citizen ofthe United States, and a resident of Canton, county of Stark, State of Ohio, have invented anew and useful lmprovementiu Copy- Holders for Type-lVriting Machines, of which the 'following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specilication.

My invention relates to an improvement in copy-holders for type writing machines,the object of which is to hold the copy before the eye of the operator and to roll it up after passing the point of vision; and it consists of the hereinafterdescribcd pa-rts and combination of parts, as set forth in the claims.

Figure l is an isometrical view ofa fragment of one forni of type-writing machines, showing my improvement. Fig. 2 is a fragment of copy-spool,sho\viug the tension-pads and manner of connecting spool to actuating-shaft.

As my invention is applicable to many of the well-known forms of typewriting machines now in use, I will proceed to describe my improvements, referring only to the type-writing machine or parts th ereofas incombination with my improvements or conjunetional thereto.

Similar letters of reference indicate corresponding parts i n all of the figures in the drawings.

Letter Z represents the frame of a typewriting machine; X, the top, a part of vwhich is removed to show the parts to which I Wish to call attention; A, B, C', and .1), the letterkeys, and E a letter-lifting lever; F, a lilik connecting the key-lever E with the escapement-lever G,which in this case is in the form of a bell-crank supported on a vibratory support, H. The free end of the lever G may be divided in the usual way of making this form of an escapement, and may be vibrated in the teeth a ofthe rack b, for the purpose hereinafter described. Said rack is connected to the paper-carriage, a fragment'of which is shown by letter h, and is supported on the rod le in the usual way.

K represents a wheel loosely mounted on a supporting pin or'shaft. (Not shown in the drawings.) Wheel K has a clutch connected with flange Z, to which is connected a toothed wheel,m,whieh engages with wheel a, mounted on shaft L, which has a geared connection with the ink-ribbon spools. (Not shown, and only referred to as this shaft L aetuates the ribbonearrying spool of many of the well-known type-writing machines.) On the reverse side of wheel K there is provided an actuatingspring, the energy of which is exerted in one direction, as shown by the direction of the arrow O. A strap, q, about the wheel K, one end of which is connected to the carriage It, as shown, completes a chain of mechanism .by which the shaft L may be rotated.

Spool M is mounted on the end of shaft L, supported between tension washers or pads 1- and s, and a requisite amount of friction applied to the head p of the spool M by the screw o', which is threaded and adapted to the threaded aperture in the end of the shaft L.

Spool M may be formed of any suitable material, preferably light sheet metal having a head,p, rimf, and flange g. In the rim fthere may be -provided a slot, d, or other means to secure the end]- of copy I). Said spool is also provided with a handle, w, hereinafter explained.

A copy-holder, R, is provided, substantially as shown in Fig. l, and may have au adjustable connection with the top X of the typewriting machine, and also to the bottom, or may be connected to the top only and projected downwardly and provided with flanges u' and perforations o as guides and tensions to hold the copy in proper positions.

The rim j" of spool M and the holder It may be of such width as may be required, adapting them to the width of copy.

The operation is as follows:` If theletter d7 be required, the key D may be struck, which operation will bring the lever E down upon the cross-bar of the link-connection F, by which the link is drawn down, vibrating the escapement-lever G, thus allowing the springactuated wheel K to move in the direction of the arrow O, by which the gear-wheels m and n are operated and a rotary movement imparted to the shaft L, by which the spool M may be rotated t-o wind up the copy, and the spools may be varied in diameter to adapt the speed by the movement of the letter-keys; but in the event of the movement of the spool,as caused by the movement of the letter-keys being either too fast or too slow, the operator may, by the use of the handle w, move the spool forward or back at such times, so that by the constant rotary motion of the shaft L, produced by operating the letter-keys, as hereinbefore stated, and the occasional advancing or retarding the movement of the spool by slipping it ou the shaft between the tension-pads, ther movement of the copy may be so regulated as' to move the unwritten word to a point of vision on the copy-holder R'most desired by the op- 'erator Having thus fully described the object and I nature of my invention, what I claim, and desire to obtain by Letters Patent, is-

1. The combination, in a type-Writinglmachine, of a copy-spool, M, copy-holder R, shaft L,and means, substantially as herein described, for rotating said shaft and spool, for the purpose set forth.

2. In a type-writing machine, a copy-spool having fiangc g, slot d, and handle w, substantially as described, and for the purpose set forth.

' 3. The combination, in a type-Writing machine, of a copy-winding spool, M, copy-holder R, provided with a guide-ange, as u, and shaft L, substantially as described,and for the purpose set forth.

4. The combination, in a typewritng ma- `c'hine, ofthe copy-spool M and copy-holder having perforations o, substantially as described and set forth, and for the purpose specified.

5. In a typewriting machine, the combination, with a copycarrying` spool and a springactuated Wheel under the control of a letteroperating key, of a connection between the spring-actuated Wheel and the copy-carrying spool, whereby the latter is regulated in its movements by the movements of the former, substantially as set forth.

6. The combination, in a type-writing machine, of the shaft L, spool M, and tension-pads r and s, and screw t, substantially as described, and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 28th day of December, A. D. 1886.

JOHN C. SKELTON.
