' Application filed-November 19, '1915. Seria1'No."62348.,

To all whom it may concern:

Be it ikl'lOVD. that I, Crmnmn SEALE, a citizen of the United States, residing at Eustis, in thecounty of Lake and State of Florida, have invented certain new and useful Improvements inMusic-Leaf Turners; and I do hereby: declare the following to be a full, clear, and exact description ofithe invention, such as will enable others skilled in the art to wh-ich it appertains to make and use the same.

This invention relates to new and useful improvements in music leaf turners andthe principal object of the invention is to provide a device to enable the performer to readily turnsheet music without necessitating the removal ofthehands from thekey board ofthe instrument.

Another obj ect of the invention is to provide a device by which music leaves may be turned in both directions thereby enabling the operator to turn back his pages in case it is necessary to repeat the-same.

Still another object of the invention is to provide a device of particularly simple construction which may be readily appliedto a musical instrument without interfering with the construction thereof.

A still further object of the invention is to provide a device which may be manually, electrically or pneumatically controlled.

lVith these and other objects in view the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure 1 is a front view in elevation of a music leaf turner constructed in accordance with this invention.

Fig. 2 is a sectional view on the line 22 of Fig. 1

Fig. 3 is a vertical sectional view through the music leaf turner.

Fig. 4c is a sectional view taken to one side of the center of Fig. 1, and

Fig. 5 is a detail perspective view of one of the music supporting frames.

Referring to the drawings, the numeral 1 designates the base of the device consisting of a strip of wood or similar material and extending upwardly from the base at the rear edge thereof is the back board 2, This back board carries a horizontally disposed guide strip 3 which is spaced upwardly from the base and cooperates with the angle member 4: in holding the movable block in place.

A suitable pin 5 extends upwardly from the base at a point centrally of its ends and forms the pivotal support for the music lea f turning frame which will be more fully hereinafter described.

Slidable between the horizontal guide strips 3 and the base 1 and betweenthe side members at and the back board 2 are the blocks 6, each of which is providedwith an axial recess 7 in which the end of the coil spring 8 is secured. As shown in the drawings it will be seen that a single-coil spring is used and normally tends to hold the two blocks inwardly toward each other and against the stops 9 which limit their inward movement as clearly shown in Figs. 1 and 2. Each of the blocks carries on its outer face a spring arm 10, the free end of which is twisted at right angles as at 11 and this twisted portion is formed with a cam face 12 forming a latch 13, which is adapted to engage the leaf turning frame in a manner which will be more fully hereinafter described. The springs 10 normally tend to move the latches inwardly toward the back board 2.

The leaf turning frames are best illustrated in Fig. 5 and each comprises a standard 14 provided at its upper and lower ends with the right angularly extending arms 15 which are formed at their outer ends with suitable clips 16 by means of which the sheet music is supported thereon. A suitable right angularly extending flange 17 is bent outwardly from the lower end of the standard 14 and is provided at its outer edge with the downwardly and inwardly inclined wall 18 which is in turn provided at its lower edge with the outwardly eXtend ing flange 19. Each of these flanges 19 is provided at one end with an ear 20, which ears are formed with alining openings 21 for the reception of the pivot pin 5 hereinbefore referred to.

It will be evident that the device is assembled by slipping the cars 21 over the pivot pin and thus pivotally mounting the frames which support the sheet music. Should the sheet music supporting frames be in the full line position shown in Fig. 1, it will be seen that upon moving the left hand block outwardly, latch 13 carried by said block will engage the wall 1.8 near its lower end and cause the frame to swing on its pivot thus turning the music sheet. After the frames have been moved as above described, the right hand block is moved and the operation which takes place is described as follows. In order to return the frames to their original positions, the opposite block is moved outwardly and it will be evident that the spring arm carried thereby will cause its respective latch 13 to engage in the inclined wall 18 near its upper edge, thus turning the frame which is engaged thereby and causing it to be swung over so that the arms of the frame point in the direction of the block which is moved.

In order to move the blocks, it is to be understood that any suitable mechanism may be employed, however the illustration shows the manual method of shifting the blocks and in this embodiment the eye 22 is secured to one of the ends of each block and secured to each eye is a flexible member 28 which passes over the pulleys 24 and is connected to a lever 25 which may be foot operated or controlled by the knee of the user so that upon moving the lever in either direction, pull will be exerted on one or the other of the flexible members, thus moving its respective block. It will be understood that each block will return to its original position after each operation by means of the spring 8.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the comblnation and arrangement of parts as will fall within the spirit and scope of the appended claim.

What is claimed is A music leaf turner comprising a base, a back board secured thereto and extending upwardly therefrom, a horizontal guide secured to the back board in spaced parallel relation to the base, guides secured to the base and in spaced parallel relation to the back board, blocks slidable within the guides, a retractile coil spring connecting the blocks and normally urging the same toward each other, stops to limit the inward movementof the blocks, a pin extending upwardly from the base board and centrally thereof, frames, flanges at the lower ends of the frames, ears extending longitudinally from the flanges and pivotally mounted on the pin, downwardly and inwardly inclined walls at the outer edges of the flanges, outwardly extending flanges at the lower ends Copies of this patent may be obtained for five cents each, by addressing the "Commissioner of Patents, Washington, D. O.
