SHEET-METAL BOOK-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 607,891, dated July 26, 1898. Application filed August 21, 1897. Serial No. 649,076. (No model.)

To all whom it may concern.-

Be it known that I, J OEL SUMNER SM1TH,.

2, a side elevation of a modification of the above, and Fig. 3 an end elevation of the form shown in Fig. 2.

Similar letters of reference represent like parts in all figures.

This invention relates to supports for books, and more particularly to that class which are adapted to be secured to shelves for books to hold the books in an upright position on the shelves; and it consists in the production of a novel form of support, which may be constructed of sheet metal or similar substance.

A metal frame-the main or upright portion of which is represented in the drawings by the letter A has two arms a and a extending at right angles therefrom at the top and bottom, respectively. To the upper arm a is riveted or otherwise secured a narrow strip or band of sheet metal B, which is bent in substantially rectangular form, Figs. 1 and 2, to constitute the support proper for the books. A strengtheningrib C may also be secured to the arm a and to the band B at the points 0 to limit the elasticity of the band. The other or lower end I) of the band B is secured to a block D, of wood or other suitable sub stance, by screws 1) or other means. Pivoted at e to the outer end of the arm a is a cam E, adapted to bear on the portion 1) of the band B, secured to the blockD. By turning the cam E by means of the handle 6 the eccentric surface of the cam forces the block D and end b of the band B downward, as

shown in dotted lines, Fig. 1, and upon the reverse movement of the cam the elasticity of the band B restores the block D and end 6 to their original positions. (Shown in full lines, Fig. l.)

A way or guide F is formed on the upright portion A of the frame, to which it is riveted or otherwise secured. 'lheway F consists of a piece of sheet metal doubled or folded to extend on both sides of the block D to guide the same in its movements.

The support; is adapted to extend across the shelf, so that the length of the band will be at right angles to the length of the shelf and the lateral edges of the band are presented to the books to be supported.

Tosecure the support to the book-shelf, the lower arm a is fitted beneath the shelf and the block D lowered by means of the cam E until the shelf is held tightly between it and the arm a. The support is released byswinging the cam back on its pivot, when the band B will raise the block from contact with the shelf.

The modification shown in Figs. 2 and 3' the block D. By means of the set-screw G,

as it is raised and lowered, the block D is raised and lowered to bind with the arm a the bookshelf.

Ido not intend to confine myself to the particular'rectangular form in which the band is shown bent.

Having now described my invention, what I claim, and desire to secure by Letters Pat: ent, is-

l. A book-support formed of a narrow band or strip of sheet metal bent about on itself so that the ends thereof will be in proximity to each other and the lateral edges of the band presented to the books, the width of the support being as great as the width of the band, together with'connection betweenthe ends of the band or strip and means for holding said support in position on said shelf, substantially as described.

2. Abook-support formed of anarrowband or strip of sheet metal bent about on itself so that the ends thereof will be in proximity to each other and the lateral edges of the band presented to the books, the width of the supsaid frame; substantially as described.

4.. The combination with a book-support formed of a band of sheet metal; of a frame having an arm adapted to fit against the book shelf, one end of the support being connected to the frame; a block to which the other end of the support is attached, adapted to fit against the oppsitoe side of the shelf; and

means for raising and lowering said block; substantially as described.

5. The combination with a book-support formed of a band of sheet metal; of a frame to which one end of said book-support is secured and having an arm adapted to fit against the book-shelf a block to which the other end of said support is secured, and which is adapted to fit against the other side of the bookshelf; and a cam pivoted to said frame and adapted to lower said block against the resistance of said support; substantially as described.

In witness whereof I have hereunto set my hand this 19th day of August, A. D. 1897.

JOEL SUMNER SMITH.
