DEVICE FOR COPY-HOLDERS.

SPECIFICATION forming part of Zetters Iatent No. 567,221, dated September 8, 1896.

Serial No. 666,138. (No model.)

To all whom/ it may concern.-

Be it known that I, AARON R. COOK, a resident of Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Devices for Copy-Holders, of which the following, taken in connection with the accompanying drawing, is a specification. ,7

My invention relates to a device for copyholders; and the objects of myinvention are to provide a means of retaining a copy-book ina convenient positionfor copying, also to secure the pages so that they may be separated as desired or held in block. I attain these objects by means of the mechanism illustrated in the accompanying drawing, in which the figure is a perspective view of my invention and copy-book.

Similar numbers refer to similar parts throughout the View.

1 is a copy-book of the usual form. 2 is a clamp formed of wire provided with a central loop 3, of rectangular or other convenient form, and horizontal bars 4 and 5, connected by the vertical bars 6 and 7 with the loop 3 10 is a link of wire having the circles 11 and 12 at either end around the curves 8 and 9,respectively, which are thereby kept in place.

By adjusting the bars 4 and 5 over the leaf desired to be shown or used in a plane different from the loop 3, which may be on the surface of the outer cover or any suitable plane, so that the leaves or part between the plane of the bars 4 and 5 and the loop 3 is held by their bearing in different planes, any number of pages may be clamped together as may be desired.

4 which are not desired to be shown unless for In a similar way the pages on the other side of the book adjoining the other cover, and

opposite copies, are held in place, and by placing the outer surface of the back part or cover is kept from slipping by its adjustment in the curves 8 and 9, as described. The clamp may be used without the link to keep any number of pages separate or retain the place of copy vice may be used for keeping music-books or other books open at an angle by placing the device, as shown,on the upper edges and allowing the book to rest on the lower edges.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a device for copy-holders, in combination, two clamps having each two horizontal bars connected with a loop by vertical bars and provided with curves as described at the j oinder of the loop with the vertical bars and a link having a circle at each end adjusted over the curves of the loops of said clamps; all substantially as described and shown.

2. In a device for copy-holders, the combination of a copy-book with two clamps formed as described one clamp having its bars on the surface of a page and the loops on the surface ofthe cover and the other clamp having its bars on the surface of a page and the loop on the other cover of said book with a link having its ends held on said clamp one at each end respectively so that said book may have its covers adapted to be tented on the edges in a steady position all substantially as described and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 16th day of September, A. D. 1895 AARON R. COOK. Witnesses: 7
