Application filed September 11, 1903. Serial No. 172,711.

To all whom it may concern:

Be it known that I, GEORGE SYMoNs BUDGE, a subject of the King of Great Britain, residing at Takapuna, Auckland, New Zealand,

have invented a new and useful Improvement in Book-Marks; and I do hereby declare the following to be a full, clear, and exact description of the same. 1

This invention has been devised for the purpose of providing means whereby the leaves of a book may be kept open at the place desired by the reader and will also serve as a book-mark.

The use of the device will save the books from the ill usage so often bestowed upon them in order to make them keep open.

The means employed consist of a base composed of a pair of clips that are adapted to fit upon and grip the book-cover. Hinged to the outside edge of this base is a plate that when opened out stands vertically at right angles to the base and which is provided with a slot running up it. In this slot a sliding piece is fitted, and to the sliding piece is hinged a flat plate that serves as the holder for the leaves. The sliding piece is provided with means whereby it may be locked at any desired point in the slot.

In the accompanying drawings, Figure 1 is a side elevation of the device in the condition for use. Fig. 2 is aback end view, and Fig. 3 is a plan, of the same. Fig: 4 is a side elevation of the hinged ends of the base-clips, showing an alternative manner of hinging. Fig. 5 is an enlarged detail View of the fingercam.

a b are the base-clips, which are hinged together at one end, as at 0. In the form shown in Fig. 1 the bottom half a of the clip has its back end turned up, and pivoted to the turnedup portion is a finger-cam cl, that is formed with a projecting pin 0. The top portion 6 of the clip projects a short distance beyond the hinge, and this projecting portion overlaps the pin 6. By turning the finger d on its pivot the pin 6 will engage with the under side of the projection of the clip I) and force it up, thus depressing the portion upon the other side of the hinge and causing the two portions of the clip to come together, so as to grip upon anything placed between.

The alternative device shown in Fig. 4: consists in a flat spring f, surrounding the hingepin and'having its ends bearing against the projecting ends of the clips at and b, so as to force them apart and force the main portions together.

Hinged to the end of the clip his a plate g, that is capable of folding down upon the clip and of being opened at right angles thereto.

This plate is formed with a slot it, running longitudinally along its middle. Fitting within the slot is a sliding piece 1', to which is hinged on its inner end the flat plate Kc. To the outer end of this plate is secured a cross-piece Z. The hinge of the plate is is preferably provided with a spring 771, whose tendency is to keep the plate is out at right angles to the plate g when such plate is in the vertical position. To the outer side of the sliding piece is attached, by means of the small thumb-screw n, a bowed spring 0, whose width is greater than the width of the slot 72, and whose ends are made to bear against the face of the plate g. By means of this spring and set-screw the sliding piece may be locked at any desired point in the slot h.

In use the base-clips a b are placed upon the edge of one side of the book-cover, when the plate Q will stand up against the edges of the leaves, the platek and cross-piece l lying in between the leaves at any desired point. This plate 76 by reason either of its weight or its spring-hinge will thus when the book is opened serve to keep the leaves from turning over. If desired, two of the devices may be employed, one being placed upon each cover, when the leaves on both sides will be prevented from turning. The plate being hinged will allow of the leaves of the book being drawn from under it without damage, so as to turn them over. When the book is closed, the device will serve as a book-mark.

When not in use, the device may be folded up into small compass by lowering the plate 9 on its hinge until it rests against the clip 6, the plate k being inv like manner folded up against the plate 9.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a book-mark, base-jaws hinged together, a cam for causing the engagement of the jaws, a plate hinged to one of the jaws, a sliding piece on the plate, means for holding the sliding piece at different adjustments, a flat plate carried by the sliding piece and a cross-piece carried by the flat plate.

2. In a book-mark, base-jaws hinged together, means for causing an engagement of specification in the presence of two subscribthe aws, a plate pivoted w1th relation to one lng witnesses.

of the jaws, said plate having a slot, a slide traveling with said slot, means for holding GEORGE SYMONS BUDGE 5 said slide in its varying positions and a spring- Witnesses:

controlled plate hinged to the slide. E. BROOKE SMITH,

In testimony whereof I have signed this T. H. DAwsoN.
