MUSIC=LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 443,626, dated December 30, 1890.

Application filed March 22, 1890. Serial No. 344,915. (No model.)

To aZZ whom, it" may concern:

Beit known that 1, JAMES MARET, of Mount Vernon, in the county of Rock Castle and State of Kentucky, have invented a new and Improved Music-Leaf Turner, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which Figure 1 is a front elevation, partly in section and broken away, of my improved musicleaf turner. Fig. 2 is a vertical transverse section taken on line 2 2 in Fig. 1. Fig. 3 is a horizontal section taken on line 3 3 in Fig. 1, and Fig. 4. is a perspective View of the end of one of the springs.

Similar letters and figures of reference indicate corresponding parts in all the views.

The obj ect of my invention is to construct an instrument for turning the leaves of music in which the leaves may be turned in succession by the liberation of spring-actuated arms; also, to provide a leaf-turner in which the arms may be used independently of each other.

My invention consists in the combination of a series of fixed ratchets and a series of sleeves carrying leaf-turning arms and provided with volute springs furnished at their outer ends with hooks adapted to engage the fixed ratchets.

The invention also consists, further, in the combination, with the leaf-turning arms, of clasps for ei'igaging the leaves of music, and of spring-catches for holding the arms, all as will be hereinafter more fully described.

To the back-board A is attached the metallic plate 13, to which are secured fixed ratchets 0, having notches (6111 their outer I edges, and provided with pairs of pins 1) in their upper surface opposite the notches. Upon a rod extending upwardly from the lower ratchet through the other ratchets are placed sleeves E, which carry the arms 1 2 3 at, and to each sleeve is secured the inner end of a volute spring F, upon the outer end of which is formed the hook c for engaging the ratchet 0. It is also provided with a handle 6?, used in changing the tension of the spring. The lower arm 1 is bent downwardly at right angles at its free end, and provided with a spring-operated clasp 6, formed of the plates ff, hinged together and furnished with a rubber lining g. The arm 1 is also provided with an auxiliary arm h, which carries a clasp e, like that already described. The remaining arms 2 3 4 are bent at right angles at their free ends, and differ in length so that they reach one over the other, as shown in Fi 1.

The arms 1 2 3 it are provided with catches t', which pass through apertures in the backboard A and are engaged by angled catchlevers 5 6 7 8, pivoted to theback of the board A at 9 1O 11 12. The upper ends of the catch* levers 5 6 7 8 pass through loops j, secured to the back of the board A, and are pressed upwardly by spiral springs Z, arranged in the loops. The lower ends of the catch-levers are bent outwardly and extend through slots in the back-board A, and are provided with knobs or keys 713.

The back-board A is provided with a shelf G for receiving the music or music book. In a hole on in the shelf G is inserted a rod D, the upper end of which extends a short distance into a socket n on the under surface of the lower ratchet O. The rod D is held in the position of use by the spring 0, attached to the under side of the shelf G.

The rod D is used for holding sheets of music or music-books on the board A. The edges of the leaves of music are received in the clasps e, and the arms 1 2 3 4c are held by the catch-levers 5 6 7 8 until they are liberated by pressing the keys 70 from left to right, when the arms are turned by the springs F. Spring-clips a are provided for holding the edges of the first and last leaves of a piece of music against the board A.

It will be observed that either of the arms may be used independently of the others, so that if any portion of the instrument should get out of order the remainder may be used without inconvenience.

When it is desired to increase the tension of the spring F, the free end of the spring is carried around and brought into engagement with another notch in the ratchet O, at the same time being placed between the pins 1) opposite that notch.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the board having a veri-ieally-apertured ledge or shelf and a spring beneath said aperture, of a rod for holding sheet-music, having its lower end within said aperture and resting on said spring, and a bearing for the upper end of the rod, whereby by pressing the rod downward and lateral]; it may be disengaged from said bearing.

In a musie-leaf turner, the combination of the fixed ratchets 0, provided with the pins 1), the springs F, the sleeves E, the arms 1 2 3 at, provided with clasps e and catches i, and the spring-pressed catch-levers 5 (J 7 8 substantially as specified.

3. In a music-leaf turner, the combination, with the board having a ledge or shelf apertured at m and provided with a spring, and the leaf-turning mechanism mounted on the board and having a lower fixed part provided. with a socket IL on its lower face, of a rod resting at its lower end on said spring and at its upper end in the said socket, substantially as set forth.

at. In a music-leaf turner, the combination of the fixed ratchet 0, provided with pins 1), the spring F, furnished with the hooked end 0 and the handle (Z, the sleeve E, and the leafturning arm, substantially as specified.

5. In a music-leaf turner, the combination, with a leaf-turning arm and means for holding; and releasing said arm, of an adjustable spring, substantially as specified.
