BOOK OR MUSIC HOLDER.

SPECIFICATION forming part of Letters Patent No. 408,428, dated August 6, 1889.

Application filed September 15, 1888. Serial No. 285,548. (No model.)

- slotted bar, and thereby attain several important advantages.

In theaccompanying drawings, Figure 1 is a plan view of my improved book, music, or other holder, and Fig. 2 is an enlarged detailed perspective view of one of the clamps, the principal parts thereof being shown separated.

In the embodiment of my invention I employ two clamps A A, which consist each of a base-plate a and an upper plate a, having, preferably, the form of an index or hand formed with pendent apertured lugs or ears a v a fitting down alongside of additional apertured lugs or ears a a supplied to the baseplate a. The apertured lugs or ears a a of the plates a. a receive and are connected together by means of a pivot-bolt Z), the ends of which are treated similarly to the process of riveting, preventing its displacement. The upper or index plates at are thus pivoted or articulated upon the base-plates a, thereby forming levers, the longer arms of which do the holding. Interposed between each baseplate a and upper or index plate a is a spring 0, preferably formed of spring metal or wire, which is wound or coiled about at its middle upon the pivot-bolt b, one portion resting upon the base-plate and its other portion bearing against the shorter arm of the upper plate or lever. The springs effect the holding of the longer arms of the levers or upper index-plates down in forcible contact with the article held thereby, as presently more fully disclosed.

The clamps AA are applied to and adj ustable upon a stretched wire support B. As shown, the latter consists of two strands of a single wire whose looped ends are secured to a rack by means of screws or pegs d. It is obvious, however, that two separate wires might be employed and each provided with loops or eyes at its ends to receive the aforesaid screws or pegs.

The wire support B does not require to be specially constructed or manufactured for the purpose, and is as little obtrusive possible when applied to any music-rack, which is'effect-ed by merely inserting the screws or pegs 61, so as to stretch the wire taut, as shown.

The wires or wire strands B B pass through eyes 6, formed integrally with the base-plate a of the clamps A.

The eyes or loops 6 e are made in the baseplates by slitting the same transversely, and in parallel planes at suitable intervals apart, and then sinking or indenting the surface of the plates intermediately of the slits, bowing the metal downward below the lower surface of the plates and leaving end apertures for the passage therethrough of the lengths of wire, the latter thus being held between the downwardly-bowed portions of the loops or eyes and the bottom of the base-plates. From this it will be seen that the clamps are capable of a sliding movement or adjustment upon the wire or supporting media to adapt them to hold books, sheet-music, or similar matter, of whatever width or size, and to hold the same effectively. This invention is also simple, cheap, and readily operated.

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

In a book or music holder, the combination, with the stretched two-strand wire support B, having looped ends, of the clamps, each consisting of the spring-actuated lever a and the base-plate a, pivoted to said lever and provided with loops e, which are formed of inwardly-bent portions of said plate and embrace the wire strands, thus attaching the elamps adj ustably to the latter, as shown and described.
