iViUSlC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 309,683, dated December 23, 1884.

Application filed December '20, 1883. (No model.)

To all whom it may concern:

Be it known that I, Jiitrns lnncv Bit'rcir innon, a citizen of the United States, residing at Hutchinson, in the county of Reno and State of Kansas, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a descrip tion.

The object of this invention is to provide means whereby the leaves of either book or sheet-music may be turned by a performer of these shelves a series of arms, A A A, do,

are pivoted on a central vertical rod, S, each to swing independently of the other.

F F, &c., represent aseries of vertical rods, one attached to each of the arms A. The lower arm, A, is just enough longer than the next arm above it to allow the rod F to swing past the end of arm A and each succeeding higher arm is shorter than the one be low it for the same purpose.

B represents a hollow or drum in the pivoted end of each arm A, to receive a spring, I), which is secured at one end to rod S, and at the other end to the said arm. The rod b is rigidly fixed in the shelves, and serves as a pivotal base, about which the spring acts continuously to move the arm from D to E. In a position of rest all the rods F are at the end E. From that position they are turned by hand to the position shown, where they are kept by catches c on the shelves E at the end D.

K is a lever pivoted at a to the frame, and provided with a linger-key, d, at one end. To the other end a rack-toothed pawl, is pivoted, having a spring, H, which acts between said key and pawl to engage the teeth of the latter with the projecting ends of the arms A.

M H represent the two parts of a post fitted to stand vertically in apertures in the shelves of the body to hold sheets of music at their fold. These two parts are formed of one continuous strip cut away cent-rally to permit the same to bend sufficiently to lold back on itself, as shown in dotted lines. The back edge of the music is placed between parts H and Bi, and the part M is brought against the side thereof. Then the handle L is pressed down,as shown,engaging in lts ca1ngroove J a pin, g, in part M, and forcing the parts M H together upon the music-sheets. The sheets to be turned are then arranged in order between the springs h and the bars F, respectively, the first sheet resting upon bar F, the next upon bar F and so on. \Vhen the performer desires to turn a sheet he has only to give a quick touch upon lever '13,, thereby raising lever A from engagement with its catch 0, thus releasing it to be turned by its spring I) over to side Fl, carrying with it the leaf resting on it. Arm A now being out of the wav, the pawl springs to engagement with arnrA". \Vhen that is releascd,the pawl engages A, and so on to any number of arms with which the device may be provided. in case the leaves of a bound book are to be turned, the central post will not be needed, and it may be drawn vertically out of the frame.

This musietnrner may be placed on the music-rack oi'any instruinentsuch as a piano or organand the middle of a book will be supported thereon, while the leaves re in place to be turned, as described.

The springs It may be secured directly to each. bar F, or to each arm A, to press against said bar to hold the leaves of music when inserted between, as stated.

\Vhat I claim as my invention, and wish to secure by Letters Patent, is

1. The combinatiomwit-h a series of shelves, E, secured together as a frame, and provided with the catches c, of a series of arms, A, pivoted between said shelves to engage the catches c, substantially as shown and described.

2. The COlilbillfltiOil,\Ylbh a series of shelves forming a frame, a series of arms pivoted therein, springs to throw said arms, and catches to retain the same, of a finger-lever pivoted to the frame, a many-toothed pawl pivoted to said lever to engage said arms, and means for pressing said pawl into engagement, substantially as and for the purpose specified.

3. The combination, with aseries of shelves and a series of music-leaf 'tnrners pivoted therein, of a bifurcated central post cut away and bent upon itself midway, as and for the purpose specified.

4. The c0mbinati0n,with a series of shelves IO and a series of music-1021f tnrners pivoted therein, of a bifurcated central post having a pin in each of its upper ends, and a lever pivoted on one of said pins, and provided witha. cam-groove to engage the other pin, as shown and described.
