HENRY II. POTTER, OF KINGIVOOI), \VEST VIRGINIA.

COPY-HOLDER.

SPECIFICATION forming part of Letters Patent N 0. 407,239, dated July 16, 1889.

Application filed April 16, 1889- Serial No. 307,425. (No model.)

To all whom it may concern:

Be it known that I, IIENRY II. POTTER, a citizen of the United States, residing at Kingwood, in the county of Preston and State of Vest Virginia, have invented a new and useful Copy-Holder, of which the following is a specification.

This invention relates to copy-holders of that class generally used by type-writercopyists; and it consists, broadly, of an uprightstand or rack adapted to be placed behind the type-writer and carrying a table to which the copy is clamped, which table is movable upwardly step by step by means of a leverhandle projecting by the type to a position within ready reach of the operator.

Theinvention also consists of further details, among which may be mentioned a magnifier for enlarging the copy, a lever for tripping the movable table to cause it to return automatically to its normal position, and other details, all as will appear from the following specification.

In the drawings hereto annexed, Figure l is a perspective view of my improved copyholder complete. Fig. 2 is a right-side elevation. Fig. 3 is a central vertical section,\Fig. 4 is a horizontal section on the lineocx of Fig.

Fig. 5 is a rear elevation. Fig. 6 is an enlarged detail of the clamps for supporting the movable table, and Fig. 7 is an enlarged detail of the operating-levers.

The same letters of reference are applied to corresponding parts throughout.

A is the base of my improved copy-holder, from which base rises a suitable rack B, provided with dovetail or other grooves b, as shown in Fig. I. Sliding vertically on the face of this rack is a table (I, having tongues c fitting said grooves, and said table has a shelf 0 at its bottom, upon which maybe rested or stood any copy which is upon card or other stiff paper. At the top of the table C, however, is located a clip D, drawn against the face of said table by Springs (7, but capable of being held away therefrom by being rested upon the heads of stops (1. A short distance below the top of the rack 13 is a transverse bar 13, carrying forwardly-proj eetin g pins B at each end, and upon these pins slides a linemarker E, as shown. The pins converge slightly toward their outer ends, thereby offering a slight resistance to the withdrawal of the marker therefrom and holding it gently in place at all times. The marker E carries two arms c, having eyes 6 at their upper ends, and within these eyes is supported an elliptical glass rod F, which will slightly magnify the matter beneath it, though this magnifier may be dispensed with, if desired.

A rod G is disposed longitudinally of the table 0 at the rear, being supported at each end, as at g. The rack B carries a pair of guides B extending from the bar B to the base A, and the vertical slot between said guides stands about opposite said rod G. Pivoted between the guides B, preferably near their upper end, is a friction-clutch H, pressed downwardly by a spring h and normally clamping said rod G to hold the table 0 at any desired elevation. A second frietion-cluteh I, having a pin 7; in its upper face, engages the rod G below the other and is pivoted in the upper end of an. arm J. The latter slides between theguides B and extends downwardly to a point below the base A, where it is pivoted to the free end of a rearwardlyprojecting lever K, which is keyed upon a shaft L and pressed normally downward by a spring 70, as shown. The said shaft L is journaled in the base A and extends across the same, projecting at the right a short distance, as shown. At this point a collar M is secured by set-screwm, said collar carrying an upwardly-projecting arm N, to which is removably secured the operatinghandle I.

Referring now to Figs. 2 and 7, a supplemental handle I is pivoted centrally beneath the handle I, and has a hole 19 fitting loosely over the end of the shaft L, beyond which point it is extended and reduced, as at P. A spring 0, carried by the handle I, presses the handle P normally in place beneath it and in contact with the collar M.

Q is a lug or block secured to the side of the rack B, and carrying a pin, nut, or other stop q, upon which the extension I normally bears in response to the action of the spring L. A thumb-screw R enters this block Q, and beneath the head of said thumb-screw is a slotted stop S, whose lower end limits the upward movement of said extension P. The

stop may be adjusted vertically by loosening the thumb-screw, as will be readily understood, for the purpose of permitting a larger movement of the extension P, and hence of the clutch I.

The operation is as follows: The device being placed at the rear of a type-writer and the copy clipped beneath the clip D, the table 0 is lowered to its lowest point and the line-marker E and magnifier F adjusted in place, when the uppermost line on the page will be exposed above the marker and enlarged by the magnifier. This line is then copied, after which the free end of the handle I. is depressed, thereby raising lever K, arm J, and clutch I. The latter, engaging the rod G, carries the table C upward until the extension P on the supplemental handle P strikes the stop S, which has been previously set, so that the table 0 can be raised at each step only the distance between the lines in the copy. The next line is then copied, and so on until the lowermost line on the page has been exposed and copied. The operator then slips the lower edge of the front page of copy out from beneath the marker E and turns it over the top of the table 0; or, if the copy be on separate sheets, the sheet just copied is removed from beneath the clip D and laid aside. The free end of the supplementary handle P is then pressed to the left by the first finger of the operators right hand and both handles depressed. The extension P clears the stop S,

the clutch I is raised above its usual limit,

the pin 11 thereon strikes and lifts clutch H, and, both clutches being thus disengaged from rod G, the table 0 falls to its original position. The next page of copy may then be copied line by line in the same manner.

If desired, the clip D may be omitted and the copy pinned or tacked to the table 0 at the top or rested upon the shelf 0' at the bottom, and, as before stated, the magnifier or line-marker, or both, may be omitted, if desired. The supplementary handle P and the lug Q and its connections may also be omitted, and the handle I depressed slightly. for linespacing and considerably to drop the table C; but an unskilled operator would often trip the two clutches in this case and drop the table 0 prematurely.

I do not limit the use of this invention to type-writercopyists, as it may be used to advantage by type-setters, pen-copyists, or even by clergymen, invalids, and other persons who desire only to read the copy, but wish to avoid the liability of losing their place by skipping lines or turning too many pages at a time. I

What I claim as new is 1. The table 0, having the stops d, in combination with the clip D and the spring d, for drawing said clip against said table or again st the heads of said stops, as and for the purpose described.
