Application filed June 12, 1920.

To all whom it may concern:

Be it known that l, LULA P. Gnarls, a citizen oi the United States. residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Adjustable CopyI-lol :ler, of which the following is a specification.

This invention relates to means for holding copy in a predetermined position to be read by the copyist. It is desirable in copy holders that the words to be copied shall be held at a definite place with relation to the eyes of the copyist so that only minimum strain and labor is involved in keeping trace of the copy while copying, the same.

Copy holders for such purposes have heretot'ore been provided and means are provided in connection therewith whereby the copy may be adjusted up as the work progresses or down for the purpose of referring to the parts that have been copied. With copy holders heretofore known to me, the space through which the portion of the copy addressed to the eyes of the copyist is exposed, allows the copyist to see more than one line of the copy at a time and consequently where two lines that are close to each other begin or terminate with the same word, there is likelihood that the copyist may become con- :tused and either omit a line, or copy one line twice.

An object of this invention is to avoid errors of this kind and this I do by providing a mechanism whereby there will be exposed to the view of the copyist only the line or lines he mav desire to view at one time.

The matter required to be copied may be in lines of diflerent heights or the lines may be differently spaced apart; and my invention includes means whereby the copyist quickly and accurately adjust the copy sight space to either the height of the type or to the width of spacing, as occasion may require.

My invention comprises a copy holder provided with two guard shutters or covers for the copy, the same being adapted to be spaced apart to provide an elongated opening through which only the reouired portion of the copy can be read; and I provide means whereby said shutters may be quickly and accurately adjusted to any width of sight opening; required in the ordinary work of copyine.

Specification of Letters Patent.

Patented Dec. 2d, 1921.

Serial No. 389,762.

I also provide means for locking the shutters in the required position.

I also provide means for detachably connecting the holder to a type-writer bar or other support so that it can be quickly placed in position for use, and as quickly, remover.

Cheapness, simplicity and combined light ness and strength are further objects.

Another object is to provide a device of this kind applicable to tyne-writer machines adapted to copy instruments into record books.

T he invention is applicable for use on other kinds of typewriters.

@ther objects, advantages and features of the invention may appear from the accompanying drawing. the subjoined detail description and the appended claims.

The accompanying drawing illustrates the invention. a

The invention comprises means adapted for use with means for supporting the copy. Such copy supporting means is preferably in the form of a feed roller 1.

The feed roller 1 may be of any suitable material and construction and provided with the usual rubber friction bands 2, to act upon the copy paper 3 in a manner well known in the art to shift the copy either up or down according to the rotation of the roller which is eftected by knobs a on the ends of the roller gudgeons or shaft 5 that is journaled in the bearings 6 on the main frame '2' which is detachably connected by clips 8 and latches 8 to bar 9 of a typewriter, not shown.

Pivotally connected to the main frame 7 by pins 10 is a swinging support in form of a lJ-bar 11. having arms provided with lateral extensions 12, 13 on which are secured stud bolts 14-, 15 and on these bolts are mounted oscillatory members, shown as disks, 16, 17.

Parallel guards or shutters 18, 19 are pivotally connected together by parallel motion means comprising pins 20, 21 and oscillatory members 16, 1?; are so arranged that oscillation of one of said members in one direction will widen the space between the guards and an opposite oscillation will narrow such space. The members 16, 1'? are preferably thin rigid disks of steel, and one oi them, as disk 16, is held on its bolt 14- by nut 22; and the pins of such disx extended so as to form a handle by which the copyist may oscillate such disk when the shutters are to be adjusted in position.

Disk 17 is held on its bolt 15 by a washer 23 and wingnut 24;; whichnut is adapted to lock the disl: 17 from oscillation. When the guards or shutters 18, 19- are properly adjusted, to any position they ma be locked.

by tightening the wing-nut so that it pinches the disk between washer 23 and the heel of the stub shaft 15.

The shutters 18, 19 are preferably thin strips of meta or other suitable material mounted on the under or rear side of the disks 16, 1'? and are yieldingly held toward the roller 1 by means of coil springs 26 mounted on the pins 10, so as to press the copy sheet 3 thereon. Springs 26 have their ends hoolred over shaft 5 and extensions 12, 13 so that their tension holds the thin spring guards 18, 19 against the copy sheet on roller 1.

The shutters 18, 19 have their adjacent edges on the forward side beveled to allow clear view between the shutters when they are adjusted close to each other.

lhe copy 3 is held tight against the triction bands 2 of roller 1 by a roller 27 mounted by journals 28 in the upper ends of the upwardly and rearwardly inclined swinging arms 29, below the level oi? the axis oi the feed roller 1.

Arms 29 are pivoted at their lower ends by pins 30 to frame 7 and are yieldingly held by springs 31 toward roller 1 to press the copy 3 onto the roller bands 2, thus holdino the sheet true and tight so that the lines or the copy will come in true position to be read between the shutters 18, 19.

By turning the adjusting member 16, the

shutters may beset the right distance apart to expose but one line of copy matter between them at one time. Clips 8 are arranged to support the holder in such pos1- tion that the line between the shutters 18,

19 is at the proper height relative to the eye of the copyist. V

In operation the copy-holder is arranged in position where it is accessible for manipulation and where the reading space between the guards is visible to the copyist. Then the copy is inserted in the holder in such position that the top line is visible between are adjusted to lines of large and small type. The operator can, with the right hand easily loosen wing-nut 2 1 thus allowing disks 16, 17 to beturned to space the shutters the right distance apart. The wingnut is normally turned to locking position except when the width of the sight slot is being changed.

Particular attention is directed to the :onstruction and arrangement whereby the guards and the tension roller yieldingly press the paper sheet 3 toward the front and back faces of the roller, respectively. In consequence of this the paper is normally held true and taut and the thin slats or guards press the paper on each side of the exposed line and holds the paper tight against the friction banded feed roller.
