Application .lcd January 20, 1925.

This invention relates to copy holders, and especially an improved combination of typewriter-copy holder and line marker.

The main objects of this invention are to provide an exceedingly capacious, strong, durable, elastic, convenient and thorough y practical device for holding large and heavy books, las well as smaller ones and single 'sheets lto be copied from by a typist; to

A further object is to provide a device of this kind thatlhas uprights or frame ele-v ments so constructed of ordinary mercantile stock, strips or bars'ofv metal, that its lower part is relatively stiff and rigid, while its upper part has suflicient elasticity to avoid permanent distortion of the device in the event a heavy book .is allowed to drop a slight distance onto the vcopy-seat.

Other objects and important features will `be pointed o ut oi implied in the following details of descri tion, in connection with the accompanying rawings in which:-

Fig. 1 is a front view of the device; Fig. 2 is a left-side view, the typwriter-frame and copy-sheet being indicated in broken lines;

and F ig, 3 is-an enlarged detail view insection along the lines 3 3, 3 3, of Figs. l and 2. L

According to th embodimentifof the invention here shown, aboard orl base-plate 5 is provided with grooves 6 in which are seated thel horizontal parts ,7 of strips of,

steel or other metal whose upright parts S are riveted to or otherwise 'rigidly united r with uprights 9 that are also formedof strips of` steel or other somewhat springy metal or material. The lower end of each part 9 extends horizontally forward'and is-` riveted or otherwise Vsecured to the, part v7, `as shown at 10, and the part 11 of each up-l right is forwardly and downwardly inclined from the part 8 to the part 10 so as to `form a brace at the corner or angular bend where the parts 7 and'S unite. Screws, as indicated, or other appropriate means may be employed' for secpring the parts in the Serial No. 3,61%

grooves 6, for rigidly uniting the base-plate or typewriter-seat with the metal 'strips that;V support the copyiseat-and'line marker.`

The copy is vindicated at C as a single sheet-,but itis' obvious that a book of large size and'of more lthan Yaverage thickness can be placed; while open, between the4 parts 13 and 19,and that the latter will serve to prevent thebOOk-,leaves from swinging forward. f l;

The parts 9, 10 A and ,11 have a= plate 20 riveted or otherwise secured thereomand an upwardly extending flange 21 combineswith In addition to the' uses of the. platesivlS,VA

19 and 20, Aasvdefined in the foregoin ,i they rigidly unite the pairs of strips, efined above, so they remain rigidlynnited even4 if the hase or plate 5 is detached or substituted by other means of securing the copy seat in a definite relation to the typewriter.

Most all oi' the structure defined in the foregoing is described and claimed in an application tiled by me on `or about the 15th day of December, 1923, Serial No. 680,913, entitled Typewriter copy holder; and I will now give further details of the improvements which include the line marker, mentioned in the foregoing:

Guiding and scupporting strips 23 and 24 are preferably riveted or bolted to the parts 12 and 15, and have apertured ends extending laterally beyond the edges of the strips that support the copy-seat, their apertures 25a and 2la being rectangular or non-cylindrical and preferably oblong. Through a pair of these apertures extends a compound adjusting har 25, consisting of an intermediate part 25a, an upper end part 25", and a lower end part 25, these latter parts extending at right angles to and from opposite ends of the intermediate part, in opposite directions, and lying in parallel planes. -The shape of this bar may be defined either as a compound curve or a compound angle, so the nomenclature compound bar7 appears appropriate. The lower part 25c is serrated or provided with a series of evenly spaced notches at 26, the spaces or pitch of these notches being preferably equal to the single spacing of an ordinary typewriter. These notches engage alternately or alternatively with the adjacent part of the bar 24, and a handle 27 is provided on its lower end for ging these notches with the bar 3'- adjusting this bar for'properly 55s iing its arm or line-index 28 with i; to the copy C.

F0 properly adjusting the arm 28 with respejt to the different forms of copy, to-

wards' and from the plate 18, the index-arm or line-index may be angularly bent at 29, and its attaching end may be apertured and screw-threaded at 30, to receive and mesh with an attaching and adjusting screw 31 having a knurled head or handle 32. The shank of this screw extends through an aperture of-the part 25a and works freely in this aperture which. is not screw-threaded. lt will be s'een, therefore, that hy loosening the screw-,31, the arm 28 is freed so that it can be ad usted to any of the positions shown in fu; and brokenlines and lto an infinite number of other positions;'and that by tightening the screw, the arm 28 is secured in angl one of its adjustedpositions.

Al ough the inclined position of the part rect-ion, tend to utilize the. force of gravity for holding the respective notches 26 in iengagement with the bar 24, and although it is within the scope olf-this invention to change the shape of eac-hnotch so that such engagement will etl'ectually be retained until the bar is manually moved for disengaging these parts and changing the adjustments ot the bar and its arm 28, it may be of advantage to provide a springfor yieldingly retaining the engagement of these parts, and such a spring is indicated at 83 of Fig. 3, being omitted in the other ligures of the drawings.

For use in connection with certain types of typewriters, it may be desirable to operate the line-marker with the left hand, instead of the right, and in such event, the bar 25l may be transferred from the positionshown to the apertured parts 23*1 and 2f'at the left side of the device, and the arm 28 may be transferred from the left side to the right side of the bar25. One or more rollers (not shown) may be journalled on the arm 28 for rolling on the copy or on the plate 18.

In operating the line marker when the copy C is on lthe copy-seat, the index-arm 28 is first adjusted so it lies near the copy and just below the first line to be copied from, and when through with thisline, the operator grasps the handle 27 and pulls it forward, then allows it to descend until the index-arm is just below the next succeeding line, then engages the notched part 26 with the bar 24 for holding the line-marker in position; and this operation is repeated until all the lines have been successively marked and copied or copied from.

It is not intended to limit my patent protection to the exact details of construction and arrangement here shown, but the invent-ive idea includes analogous devices within the scope of the claims.

lVhat I claim as my invention is:

1. A copy holder which includes two spaced pairs of relatively thin and wide springy strips, the strips of each pair having their wide sides confronting one another, a horizontal plate to be seated on a table and to extend under a typewriter, a copy-holding plate, and means securing the copy-holding plate to the spaced pairs of strips over said horizontal plate, said strips of each pair including horizontally extending parts which are superposed upon one another and upon said I horizontal plate. and secured to the latter, said strips having juxtaposed parts fixedly secured to one another at points above said horizontal plate and thus forming relatively stiff upright supporting part-s, the parts of saidstrips which extend up from .said stiff upright. parts to said copy-holding plate being, forwardly and downwardly 24, and ofthe part 2.5 inthe opposite'di-A bowed and s paced from one another to provide aspringy support for said copy-holding plate. Y

2. The combination of a eopyseat including an upright part against whichthe back ,of a copy cane-rest, a supporting structure melding the eo yseat in position tu permit, a typewriter to e positioned undef the copyv seat, this supporting structure inciuding apertured elements, a bar including n ser mated part and being sldable u :and down in :leid niieituwd elements ami] mijustisbie te fiitwr'm; pueitiuia by interchangeable engagemem iii the seimtions with one 0f said apei'tured elements, and a line-index arm carried by said bar, substantially as shown, for the purpose Specified.

3. The structure defined by claim Q, said -arm being adjustable towards and from said upright part, and manipulative means to secure said arm in its dierent adjust- .e

intermediate part crossing the plan(- n which lies the said upri ht part. of the eopyseat, the parts that sli e in snif] :ipeztm-eii elements extending in 'planes in front und in rear of the first said piane and 'subeatniiV tinlly parallel therewith.
