MUSIC-LEAF TURNER.

Specification of Letters Patent.

Application filed November 26, 1910.

Patented Nov. 28, 1911.

Serial No. 594,372.

To all whom it may concern:

Be it known that I, IRA E. VVA'rsoN, a citizen of the United States, residing at Plainview, in the county of Pierce and State of Nebraska, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in music leaf turners and has for its object to provide a mechanism of this character which is comparatively simple, efficient and positive in its operation and which may be con veniently arranged for turning sheet music arranged upon a piano or music stand.

Another object of the invention resides in the provision of a plurality of leaf carrying arms, and treadle actuated means for swinging or rotating the arms to turn the music sheet by sheet.

A still further object of the invention is to provide means for reversing the movement of any one of the sheet carrying arms afterthe sheet has been turned to return the sheet to its normal position so that the music written thereon can be repeated.

With the above and other objects in view, the invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a sheet music turning device embodying my improvements; Fig. 2 is a side elevation thereof; Fig. 3 is a section taken on the line 33 of Fig. 2; Fig. 1 is a section taken on the line 4-t of Fig. 1; Fig. 5 is a detail perspective view of one of the sheet holders or clasps; and Fig. 6 is a transverse section thereof.

Referring in detail to the drawings 5 indicates a base upon one edge of which an upright or standard 6 is mounted, braces 7 being secured to the standard at its lower end and resting upon the floor or other supporting surface. A music supporting frame comprising a central pivot rod 8 and the sheet carrying frames 9 are arranged upon the upper end of the standard 6, said standard being provided with a socket to receive the pivot rod 8, so that said rod and the sheet frames may be readily removed therefrom. The frames 9 are pivotally mounted upon the rod 8 and carry suitable clasps 10 for securing the music sheets to the same. Upon these clasps a depending pivoted finger 11 is arranged for movement in one direction.

A tube 12 is rotatably secured upon the upper end of the standard 6 in the annular bands 13 and a longitudinally movable cylinder 14 is adapted for movement in said tube. This cylinder is formed upon the upper end of a rod 15 and is disposed at a slight inclination thereto. The lower end of the rod 15 is pivotally connected to a foot treadle 16 which is mounted upon the base block 5. A spring 17 has one of its ends secured to the standard 6 and its other end to the rod 15 and normally acts to force said rod upwardly, thereby also forcing the cylinder 14 into the tube 12. The cylinder 14:, it will be observed is provided in its periphery with a spiral groove 18 into which a stud 19 fixed to the wall of the tube 12 extends. Upon the tube 12 and between the annular bands 18 a coiled spring 20 is disposed. One end of an arm 21 is extended between the upper coils of the spring and said arm is moved longitudinally of the tube in a slot 22 provided in the tube 12 by the spring 20. The upper end of the coiled spring 20 is laterally extended and an operating wire 23 is connected thereto, the lower end of said wire being secured to a foot treadle 24 which is also mounted upon the base 5. It will be noted that the upper outer ends 21 of the arms 21 are disposed in substantially parallel relation to the lower edges of the sheet carrying frames 9. I

In the operation of the device, the music sheets are placed in the pivotally mounted carrying frames 9, any number of which may be provided. In the normal position of the parts, the extremity of the end portion 21 of the arm 21 is disposed behind the hinged finger 11 and when it is desired to turn a sheet from the right to the left, the operator releases the foot treadle 16 by moving a catch 16 which normally holds the same upon the base and places the spring 17 under tension. This spring will then contract and force the rod 15 upwardly and extend the cylinder 14 into the tube 12. The disposition of the pin 19 in the spiral groove 18 of the cylinder will cause the tube 12 to rotate in the supporting bands 18. The arm 21 is held in the upper end of the longitudinal slot 22 of the tube, by means of the spring 20 and when said tube rotates, it will be obvious that the arm will be carried with it which in turn will swing the sheet carrying frame upon the pivot rod 8 and move the same to the left so that the reverse side thereof can be read by the musician. In order to turn the next succeeding sheet of music, the operator simply presses down upon the treadle 16, thereby reversing the rotation of the cylinder 14 in the tube 12, the end of the arm 21 engaging the pivoted finger 11 and swinging the same so that said arm moves behind the finger. The treadle 16 is then held upon the base 5 so that when released, the next sheet of music will be turned. The hook 25 has its extremity disposed below the pivoted finger 11 and extended beyond the same for engagement by the end of the arm 21 as will now be described.

It is often necessary to repeat certain measures of music and for this purpose means must be provided for returning the sheet to its normal position. I accomplish the desired end by means of a hooked arm which is carried by the sheet carrying frame 9 and is arranged adjacent to the hinged finger 11. As the arm 21 is disposed upon the same side of the hinged finger 11 in either position of the frame, in order to disengage the arm therefrom and to engage it with the hook 25, the treadle 24 is forced downwardly which draws upon the wire 23 and forces the spring 20 downwardly on the tube 12. This movement of the spring coils moves the rod 21 in the slot of the tube and disposes its upper outer end below the finger 11 and in the hook 25. A suitable latch 2-4: is now moved over the foot treadle 24: to hold the same down. The operator then steps upon the treadle 16 to move the cylinder 14; out of the lower end of the tube 12, thereby reversing the rotation of said tube and moving the arm and the sheet carrying frame 9 from left to right.

From the foregoing it is believed that the construction and operation of my improved sheet music turning mechanism will be readily understood. The device is comparatively simple in construction and very positive in operation. It may also be conveniently arranged in position with relation to a music stand or piano by making minor changes in the construction of the piano or stand so as to readily adapt the turning device to such use. As but very few elements are employed in the construction it will be obvious that the device can be manufactured at a low cost and that it will also be extremely durable and highly eflicient in practical use.

While I have shown and described the preferred construction and arrangement of the various parts, it will be understood that the device is susceptible of considerable modification without departing from the essential feature or sacrificing any of the advantages thereof.

Having thus described the invention what is claimed is 1. In a device of the character described, the combination with a support, a tube rotatably mounted on said support, a foot operated cam longitudinally movable in the tube with relation thereto to rotate the tube, a stud carried by the tube cooperating with said cam to rotate said tube, an arm slidable on the tube and rotatable therewith, a sheet carrying frame having means thereon for engagement by said arm whereby the frame and sheet are turned in one direction when the tube is rotated, means for moving the arm out of engagement with said last named means, and additional means carried by the sheet carrying frames to be engaged by said arm to turn the frame and sheet carried thereby in the opposite direction when said tube is reversely rotated.
