|V|US|C -LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 761,524, dated May 31, 1904.

Application filed December 15, 1903. Serial No. 185,225. (No model.)

To all whom i'/; may concern:

Be it known that I, LOUIS S. MILLER, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Music- Leaf Turner, of which the following is a full, clear, and exact description.

This invention relates to improvements in devices for turning sheets or leaves of music,

purpose that will be simple in construction and inexpensive and that may be easily adapted to a piano or similar instrument or to a music-rack and by means of which the leaves of music may be consecutively turned without interfering with a persons playing.

I will describe a music-leaf turner embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of a musicleaf turner embodying my invention, showing it as attached to a piano. Fig. 2 is a sectional view showing the turning mechanism. Fig. 3 is an elevation showing the releasing mechanism employed. Fig. t illustrates a leaf-supporting frame attachment that may be employed when the device is not used in connection with a music-rack or piano. Fig. 5 shows the end of one of the turning-arms. Fig. 6 is an end view of a single-sheet holder that may be employed. Fig. 7 is a perspective view of an operating-lever that may be used. Fig. 8 is a section on the line a 00 of Fig. 2, and Fig. 9 is a section on the line 1/ y of Fig. 4:.

The music-leaf turner comprises a cylinder 1, having a removable top 2, and extended upward through the cylinder is a shaft 3, on the upper screw-threaded end of which are clamping nuts or plates 4. 5, engaging, respectively, with the upper and lower side of a clip-plate 6, designed to engage with the base-board 7 of a music-rack. As here shown, this clip 6 consists of a plate of metal folded to form upper and lower members, (see Fig. 9,) and preferably it will be provided with a lining 8, of soft material, such as felt, to prevent marring of the music-rack- Mounted to rotate on the shaft 3 is a sleeve 9, and rotating on the sleeve 9 is a sleeve 10, while a sleeve 11 rotates on said sleeve 10. The upper or outer end of the sleeve 11 is attached to a disk 12, which bears upon the top 2 of the cylinder. A similar disk 13 is attached to the outer end of the sleeve 10, while a disk 14 is attached to the upper end of the sleeve 9. A coiled spring 15 is attached at its inner end to the sleeve 9 and at its outer end to a cup 16, in which the spring is placed. Springs 17 18 are connected, respectively, to the sleeves 1O 11 and are arranged in cups 19 20 and are connected at their outer ends to said cups.

As clearly shown in Fig. 8, the cups are provided at one side with openings, the walls of which engage at the opposite sides of a rib 21, formed on the inner side of the cylinder,

- and thus the cups are held from rotarymotion,

Extended outward from the disks 12, 13,

and '14: are arms 23 24 25. The end of each arm is provided with a double coil 26, and between the coils a music-leaf is designed to be inserted. Secured to one side of the cylinder is a casing 27, movable vertically, in which is a holding-bar 28, designed to hold the leafengaging arms in one position against the resistance of their springs. This holding-bar moves through openings in the top and bottom walls of the casing, and at one side it is provided with a series of notches 29, corresponding to the number of turning-arms, and it may be here stated that while I have shown but three turning-arms more than this number may be employed, if desired.

Arranged to swing in the casing is an arm 30, which is held yieldingly upward by means of a spring 31, and pivotally connected to the arm 30 is an escapement-lever 32, the lower tooth 33 of which is designed to engage the walls of the notches 29, as will be hereinafter described. The outer portion of the escapement-lever engages with a finger 34%, extended laterally from the arm 30. This lever 32may be provided with a finger-piece 35, on which a person may place his fingers to move the lever downward; but preferably the movement of the lever is caused by the pressure of the.

players knee, and therefore I attach a chain 36 to the lever, and this chain passes down through an opening in the keys or between two of the keys of a piano and through an opening formed in the key-box and connects at its lower end with a crank-lever 37, mounted to swing on the lower side of the key-box. Obviously by forcing the depending portion of this lever 37 laterally the part at right angles thereto and engaging directly with the chain will be swung downward, consequently pulling the lever 32 downward.

Extended upward from the nut i is a plate 38, designed to be placed against the rear of the music-sheets at the center, and extended upward from. the part 3 is a rod 89 for engaging with the sheets at the front and at the center.

In the operation of the device as so far described the several arms are to be turned to the right and connected with consecutive leaves of music. The bar 28 when moved upward will engage against the front sides of the several arms and will be held in its elevated position by the pressure of the'arms. When it is desired to turn a leaf, the escapement-lever, with the arm 30, is to be moved downward, so that the tooth 33 by engaging with the lower wall of a notch will move the rod downward to release the upper arm. Upon releasing the pressure the spring 31 will move the arm 30 and the escapementlever back to normal position, and then the upper tooth of the escapement-lever by engaging with the bar or casing will limit the upward movement. Then to turn the sheet held by the second arm the bar 28 is to be moved downward one step, as before mentioned.

As a means for holding a single sheet of music I provide an attachment consisting of a metal strip 40, having its upper and lower ends folded to form clip portions 41, between which the edge of the single sheet may be secured, and these clip portions are also designed to engage around the rod 39. It may be sometime necessary to use the device under other conditions than securing the same to a piano, as heretofore mentioned. In other words, I have provided a means for supporting the device on a table or the like, which consists of a frame comprising side bars at). 3, which at the lower ends have threaded extensions 44,

which pass through openings in the upper and 6 5 lower members of the fastcningdevicc 6, and

engaged with these threaded portions arelcgs.

4:5, having rubber buttons or cushions &6 at their lower ends. The upper ends of the rods A2 43 are removably connected to a cross-bar 47. As here shown, the said bars 4:2 &3 have interior screw -thrcads at the upper ends, which are engaged by headed bolts &8, which pass through openings in the cross-bar A7.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1.
