COPY-HOLDER.

Specification of Letters Patent.

Patented Jan. 22, 1918.

Application 'filed January 28, 1914. Serial No. 815,026.

T0 all whom t may concern:

Be it known that I, Gnoiien C. Bauman, a citizen of the United States of America, and resident of Iochester, Ain the county of Monroe and State of New York, have invented certain new and useful Improvements in Copy-Holders, of which the following is a specification.

rlhis invention relates to copy holders and particularly to device adapted for use in holding books or other copy, primarily for use in association with a cam-era in order that copy supported by the holder may be photographed or photographically printed.

One of the main objects of the invention is to provide novel means for holding` a book in a manner to permit a display of the full contents of a page and especially to reveal the printing at the inner margins of the leaves which are sometimes dii'licult of access by reason of the fact that the binding is such as to situate the printed or written matter at the inner margins of the pages close to the stitching` or leaf-holding elements. y

A further object of the invention is to provide a book holder having means for flexing the bound portion of the book and for pressing it outwardly while at the same time retaining the covers of the book in open position, means being provided for pressing the open book and holding the same on supports While at the same time exerting pressure on the flexed part of the book thereby causing a pressure at the angle of the open parts of the book tending to separate the pages at points close to the line of stitchings or fastenings utilized in the binding of the leaves.

It has beenr found in practice that with the use of a copy holder of the character stated, the leaves of a book near the fastenings may be pried apart or separated to such an extent as to reveal the contents of the pages, which contents would'be invisible at or near the inner margins of the leaves were the book simply opened in the ordinary manner. The inventor has, therefore, provided means for photographing or photographically printing pageswhich would ordinarily be inaccessible in photographing or printing by the usual process.

A further object of this invention is to provide novel means for causing the device which presses the binding outwardly to adjust itself t0 dierent positions with relation to the binding so that regardless of the number of pages which are on one side or the other of said pressing device, it will operate to force the binding outwardly and spread the pages at their junctions.

The invention consists in the broad idea to be set forth in the claims during the prosecution of the application, the said claims to be of such scope as to give protection commensurate with the inventive act in view of the state of the art when the said invention was produced.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this` specification wherein like characters denote correspond ing parts in the several views, and in which- Figure l illustrates a perspective view of a copy holder embodying the invention;

Fig. 2 illustrates a vertical sectional view thereof;

Fig. 3 illustrates a view in elevation of one end of the copy holder;

Fig. 4 illustrates a view in elevation of the opposite end thereof;

Fig. 5 illustrates a view in perspective of the book supporting elements and parts associated therewith; and

Fig. 6 illustrates a longitudinal sectional view of the copy holder.

In these drawings 7 denotes the casing, one part of which is horizontal and the other at an angle thereto, the said casing having a rod 8 extending through its sides and forming a support for the hinged brackets 9, which hinged brackets are angular as shown in Fig. 2 and are connected to the rod 8 at the angular portions thereof.

Each bracket 9 has pivotally connected to it, a backing plate 10, each of said backing plates having ears 11 which are mounted on pins 12 extending through the brackets. The backing plates 10 may be of any appropriate material, that is to say they may be made of metal or wood.

The backing plates have their inner edges separated and t-he space therebetween is bridged by a flexible strip 13 secured in any appropriate manner to the backing plates.

The angles of the brackets form seats for the sill 14 the same being angular in cross section and one of its surfaces forming a bearing for springs 15. The outer ends of the springs are connected to a rocking head 1G, the inner surface of which is iiat and the outer surface of which is in 'eferably convex and bears against the flexible strip 13 to which it is secured by the fastenings 17. By reason of the fact that the head 16 is supported by the springs, the said head may rock transversely to assume different positions with relation to the angle between the backing plates. The provision for the allowance of the rocking` motion of the head permits the said rocking head to accommodate itself to the flexible portion of a book between the backs thereof according to the thickness of the book and according to the side which is thickest. When the book is opened at about the middle thereof, the head would assume the position shown in Fig. 2, whereas if a greater number of leaves were on the horizontally Ydisposi-2d backing plate, the head would assume a different position automatically according to the relation of the upper to the lower portion of the book when in open position. rPhe horizontally disposed backing plate is held elevated by the spring 1S as shown in Fig. 2, thus insuring that the upper page of a book when open sh all be pressed against the glass of the frame to be presently explained.

In order to resist the outward pressure of the head 16 under the influence of the springs7 a frame 19, angular in end elevation is movably supported with relation to the casing` and to an end of the frame, a block 21 being provided at the angle of the frame to strengthen the structure and to provide an element to which a butt of the hinge Q0 may be secured. A block 9x2 is also provided at the angle of the frame at the end opposite the hinge. the said block being engaged by a latch 23 pivoted on a bracket Zet secured to the easing, the said latch having an angularl end forming a shoulder to engage the block Q2 when the frame is in proper relation with respect to the backing plates 10. The frame 19 may be of any appropriate construction to retain the glass plates 25 and 2G, the latter of which has its edge resting on the upper surface of the plate 25 to aid in resisting the pressure resulting from the application of the frame to a book and in pressing the book against the head 16V at the angle thereof.

It will be apparent from an inspection of lig. 2 that the side of the book resting on the horizontally disposed backing plate will automatically determine the position of the vertically disposed backing` plate and vice versa. as the varying dimensions of the book y on each side due to the manipulation of the leaves of the book will require compensation in the backing plates in order that the book maybe held at proper position with Arel ation tothe frame and glass carried thereby. It is furthermore apparent that this copy holder may be employed with a camera in which the lens has its axis horizontally disposed or when it is used in' connection with a lens, the axis of which is vertically disposed, since it is possible to photograph tln'oughthe horizontally disposed plate 251 Vor the vertically disposed plate 26".

I claim- 1. In copyholder, copy supports for re# taining` part of the copy 'at an angle with relation to another' part of the copy, means between the said supports and having reci'pL roca-l movement for exerting pressure on the? copy at the angle thereof, and means for' angle to each other, means for yielding'lv holding the copy supports. means betwe n the copy supports for pressing copy outs wardly, and angular means for holding th'eV copy against the supports and the last mentioned means.

fl. In a copy holderc means for supporting hound sheets in open position7 means 1nounted to move outwardly between the first metil' tioned means for exerting pressure on thesheets substantially at their junction, and angular means pressing the copy at the angle thereof for resisting the pressure of the said means for exerting pressure.

5. In a copy holder, backing plates, lmeans for supporting the backing plates at an an; gle to each other, a flexible connection between the adjacent edges of the backing plates, means for exerting pressure on the flexible Vconnection and a member enacting with the pressure exerting means for wedging the leaves of a copy at their points of attachment to each other.

In testimony whereof, I aflix my signature in the presence of tivo witnesses. Y

ono-nen nninrryn.
