COPY-HOLDER.

SPECIFICATION forming part of Letters Patent No. 5 18,0 80, dated October 15,1895.

Application filed April 19, 1895. Serial No. 4 i (N0 model.)

To all whom/zit may concern.-

Be it known that I, JOHN MoOLURE, J r., acitizen of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented a. new and useful Copy-Holder, of which the following is a specification.

My invention relates to copy-holders, and has for its object to providea device with means for operating the liner Without direct movement thereof by the hand, the extent of movement being regulated by a gage to agree with the distance between the lines of the copy, said liner being adapted to rest at its indicating-edge against the face of the copy and being provided with means for adjustment angularly and toward and from the plane of the holder, and, furthermore, to provide means for extending the holder to accommodate copy of greater width than the ordinary legal size, such as books, time.

Further objects and'advantages of the inven-' tion will appear in the following description and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective View of a copy-holder constructed in accordance with my invention, the same being provided with extension-bars forming a part of the holder. Fig. 2 is a vertical section of the same. Fig. 3 is a detail view of the slide and the arm carried thereby for supporting the liner. Fig. 4 is a detail side view of the means for regulating the throw of the key. Fig. 5 is a rearview of the holder.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

1 designates a plate of sheet metal or its equivalent,which forms the body of the holder, the same being supported in its proper position by means of a base'consistin g of looped front standards 2, rear standards or feet 3, connected to the front standards by the inter- Vening arches 4, and inclined braces 5, said arches being connected at intermediate points by means of transverse brace-rods 6. vEach member of the base comprising a front and a rear standard, the connecting-arch and the inclined brace may be constructed of a single blank of wire or red, as indicated in the draw ings.

At the bottom of the plate forming the body portion of the holder is the forwardlyprojecting rest 7 to support the weight of the 5 5 copy, and mounted in suitable keepers 8 at the upper angles of said plate are the trunnions 9 of the spring-clamp 10, said clamp being of a looped form and being normally held in position to engage the upper edge of the copy by means of a plate-spring 11, which engages a stud 12 on one of the trunnions of the clamp.

Arranged parallel with one side edge of the holder are the spaced guide-rods 13, secured at their upper and lower ends, respectively,

in brackets 14 and 15, the former being secured by means of a bolt 16 to the body of the holder and the latter being secured by a clamp 17 to the adjacent front standard. Mounted upon these guide-rods is a slide 18,

having guide-openings 19 to receive the rods and by frictional contact therewith prevent the accidental movement of the slide thereon.

The slide is provided with a central open- 7 5 ing 20, through which extends a ratchet-bar 21, fitted to slide at its upper and lower ends in openings 22 in the upper and lower brackets and connected at its lower end to. a lever 23, which is fulcrumed upon the lower bracket and carries a key 24:. A pawl 25 is carried by the slide in position to engage the teeth of the rack-bar, said pawl having a finger-hold 26, by which it may be disengaged from the teeth to allow the slide to be adjusted either up- 8 Wardly or downwardly. The rack-bar extends above the upper bracket and terminates in a cross-head 27, between which and the upper side of the bracket is arranged a coiled spring 28 to elevate the bar after each depres- 9o sion by the key-lever, and mounted in said cross-head is an adjustable gagescrew 29, terminating at its upper end in a milled head 30 and adapted at its lower end to engage the upper bracket and thereby limit the downward movement of the rack-bar against the tension of its return-spring. A brace-rod 31 connects the upper and lower brackets in rear of the plane of the guiderods upon which the slide is mounted.

In a transverse opening 32 in the slide is mounted a stud or projection 33 upon the extremity of an arm 34, said stud or projection being held at the desired adjustment in the opening by means of a thumb- screw 35, 1 and bymeans of this stud or projection the ter to bear against the surface of the copy.

Inasmuch as the liner is free to swing around the arm as a center, it is obvious that the indicating-edge thereof will move to accommodate inequalities in the surface of the'copyQ 'In order to provide for placing abook or other large copy uponthe holder,I,alsoem- 'ployextensiomarms at the'opposite edge of thebody of the holder from themeansjust described for operating'the liner, the lowermost extension-arm 39havin'g a stem 40 fit-j ting in a sleeve 41 at'the front edge ofthe rest at the bottom of the holder and terminating at its outer end in a standard 42, adapted torest at itslowerend'on thetable or desk, a horizontalsupport 43 connecting said standard with the extremity ofthe'st'em to form a rest forthe lower edge ofthebookf An upper extension-arm 44 is provided with a stem 45, fitted in asocket 456 in rear ofthe upper edge of the holder, and an intermediate extension-arm 47 isprovided with a stem'48,

fitting in'a sleeve 49 at an intermediate point of the rear of the holder and terminates atits outer'end in a hook 50 for engaging an inter mediate point of the outer edge of thecopy,

The liner being mounted to slide upon the arm providedfor its support may be adjusted to indicate copy'uponeitherpage of the bookf .t The operation of th'improved copy-holder will be readily understood from the foregoing description, it being obvious that with the parts adjusted as indicatedthat is, withthe' gage arranged to suit the interval between the lines of the copyand the liner adjusted to bear properly against the page-the inter mittent adjustment of the liner to indicate successive'lines is accomplished by depress ing thekeyelever, and it will heseen'thatthe operation of "the liner is thus rendered new: rate and is accomplished with small loss of time to the operator. 1 It is obvious that various changes in'the form, proportion, andtheminor details of construction may be resorted to without departing from the spirit or sacrificing'any of the advantages of this invention.

Having described my invention, what claim is-- 1. In a copy holder, the combination witha plate and means for supportingthe same, of a slide mounted for movement parallel with the plane of the plate, means for impartinga step by step movement to the slide, and a liner carried by the slide andmounted thereon for angular adjustment parallel with the plane of the plate and forward and rearward adjustment perpendicular to the plane of the plate, substantially as specified.

2. In acopy holder, the combination with a plate and means for supporting the same, of a slide,"means for imparting a step by step movement thereto, an arm supported by the slide and provided with a stud or projection fitting in an opening in the slide whereby said arm is adapted to swing in a plane parallelw'iththe plate, said stud or projection being adjustable longitudinally in the opening to varythe distancebetween the arm and the plane of the plate, and means "fol-securing said stud or projection in'the opei'iingwith I the arm in the desired position, substantially as'specified.

8.In a copy holder, the combination with a plate and means for supporting the same, of
