MUSIC-'LEAF TURNER.-

SPEGIFIGATION forming part of Letters Patent No. 793,950, dated July 4, 1905.;

Application filed August 5, 1904:. Serial No. 219,673.

To all whom, it may concern;

Be it known thatI, O'r'ro Gr. PAINTER, acitizen of the United States, residing at Racine Junction, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following. is a specification.

This invention. relates to devices for turning sheet-music or the leaves of a music-book; and one of its objects is the production of an improved device of this kind adapted to be supported upon the .instrument being played or upon a suitable stand.

Another object of the invention is to produce a music-leaf turner capable of turning the leaves or sheets in either direction'that is, from right to left or from left to right of the musician.

The invention further refers to the details of construction hereinafter set forth.

In the accompanying drawings, Figure 1 is a front elevation of a music-leaf turner embodying the features of my invention. Fig. 2 is a vertical central section through the turner on dotted line 2 2 of Fig. 1. Fig. 3 is a detail sectional View through one of the sheet-holding clips on dotted line 3 3 of Fig. 1. Fig. A is a sectional view through the easing on dotted line A 4: of Fig. 2. Fig. 5 is a similar view on dotted line 5 5 of Fig. 2. Fig. 6 is a fragmental vertical sectional view taken on aplane at right angles with the plane of Fig. 2. Fig. 7 is a detail perspective view of the dogs for grasping the leaf-holding arms. Figs. 8 and 9 illustrate a modified construction of the means for engaging the leaf-holding arms, Fig. 8 being a front elevation, and Fig. 9 a vertical section on dotted line 9 9 of Fig. 8.

In the embodiment herein shown of this invention the music-leaf turner is supported This construction permits of tilting the turner to any desired angle with a vertical line.

The music rests upon a support 5, comprising the arm 6, fixed to and extending downwardly from the casing 2, to'which arm 6 is adjustably secured a T-shape arm 7 by means of a clamping-screw 8, passing through the lower end of the arm 6 and an elongated slot 9 in the arm 7. The adjustment just described is provided in order to adapt the support 5 to sheets of varying size. The support 5 also comprises a horizontal bar 10, fixed .to the arm 5, which bar 10 is furnished with springclips 11, adapted to grasp the upper edges of the covers of a book or the first and last sheets of a piece of sheetmusic. The remaining sheets, being those that require to be turned, are each held by an arm 12, provided with spring-clips 11 and having a top flange 13, against which the upper edge of the leaf may abut. The arms 12 are supported in the manner to be next described, so as to have a swinging movement from one side to the other of the support 5.

In the lower end wall of the'casing 2 are formed a central opening 14: and a sem circular slot 15, concentric with said opening. At one of its ends the slot 15 communicates with a short radial slot 16. Each of the arms 12 is provided at one end with two angular upwardly-extending projections 17 and 18, the projection 17 being adapted to enter the central opening 1A and the projection 18 the radial slot 16. When the projections 17 and slot 16, respectively, the arm 12 may be swung from side to side of the casing 2 and the support 5, the vertical portion of the pro ection 18 moving through the semicircular slot 15.

The mechanism for moving the arms 12, and thus turning the sheets of music, will next be described. A shaft 19 is rotatably supported in the longitudinal center of the easing 2, its upper end lying within an opening 20 in the upper end of said casing. Intermediate its ends the shaft 19 extends through a partition 21, fixed within the casing and extending transversely thereof. Above the partition 21 the shaft 19 carries a barrel 22,

18 are inserted into theopening 14 and theand between said barrel and the upper end wall of the casing 2 is a coil-spring 23, secured at one end to the casing and at its other end to the shaft 19 in any suitable manner, as by the pin 24:. 'The spring 23 tends to rotate the shaft 19 toward the right, Figs. 1 and 2. For rotating the shaft in the opposite direction I provide a chain 25, fastened at one end to the barrel 22 and extending around said barrel, through an opening 26 in the side wall of the casing 2, through the tubular supporting-arm 1, and downward to a pedal. (Not shown.) Depressing the pedal will rotate the shaft 19 to the left, Figs. land 2, against the tension of the coil-spring 23.

A disk 27, rigidly mounted upon the shaft 19 and rotating in contact with a circular flange or track 28, carries in an opening 29 near the edge of said disk two dogs 30 and 31 for engaging the arms 12. The lower end of each of the dogs is rounded, as at 32. At its upper end and on the side toward the center of the disk 27 the dog 30 is provided with a projection 33, having an inclined lower face. The dog 31 at its upper end, on the side toward the periphery of the disk 27, is provided with a similar projection 34. Flat springs 35, fixed at one of their ends to the disk 27 and at their other ends engaging recesses 36 in the dogs 30 and 31, hold said dogs downward. The dogs 30 and 31 are moved upward against the tension of the springs 35 by means of cam- fingers 37 and 38. These fingers are formed of spring material and have integral ofl'set bases 39, by means of which they are securedto the partition 21. WVhen the disk 27 is rotated in the direction of the arrow, Fig. 4:, the projection 33 on the dog 30 will ride upon the cam-finger 37, raising said dog. Upon a rotation of the disk 27 in the opposite direction the projection 34: on the dog 31 will ride up on the cam-finger 38 and said dog thereby be raised. As soon as the projections 33 and 34 pass their respective cam-lingers the flat springs 35 return the dogs to their normal lower position.

In use the sheets of music are secured to the stationary bar of the support 5 and to the swinging arms 12 by means of the clips 11. As many arms 12 are provided as there are sheets to be turned. The dogs 30 and 31 are normally in engagement with the projection 18 on the outermost of the arms 12 at the right, Fig. 1. When it is desired to turn a sheet to the left, the operator depresses the pedal, the shaft 19 being rotated, by reason of the chain connection between said pedal and said shaft, against the tension of the coilspring 23. The disk 27 being fixed upon the shaft 19 rotates therewith and carries the dogs and 31, holding between them the foremost arm 12 around to the other side of the support 5. Upon completing a quarter rotation the projection 33 on the dog 30 comes into engagement with the cam-finger 37 and said dog is raised, permitting the arm 12 to fall by gravity to the left. The pedal being released, the coil-spring 23 rotates the disk 27 to the right, in which movement the rounded lower end of the dog 31, striking against the projection 18 on the then foremost arm 12, rides over said projection and drops down upon the other side thereof. Said arm is now held between the dogs 30 and 31 ready to be turned to the left. \Vhen it is desired to move the music-sheets from the left to the right, the pedal is depressed far enough to move the disk 27 to the extreme left. \Vhen the dog 30 strikes the foremost arm 12 on the left-hand side of the support 5, it is forced over said arm. hen the pedal is released, the coil-spring 23 rotates the disk 27 to the right, said disk carrying with it the arm 12, which had been grasped by the dogs 30 and 31. Upon reaching the middle point of its movement the projection 34: on the dog 31 engages the cam finger 38, and said dog is raised, releasing the arm 12 and allowing it to fall by gravity to the extreme right. The disk 27 is now returned by the operation of the pedal to the left, where the dogs 30 and 31 grasp another arm 12.

In Figs. 8 and 9 Ihave illustrated a slight modification in which a star-wheel is substituted for the dogs 30 and 31. 10 is the star wheel mentioned, said wheel being rotatably mounted in a suitable support 41, fixed with relation to the shaft 19. The free rotation of the wheel 10 is prevented by any suitable means, as by a spring 42 frietionally engaging said Wheel. In this modified construction the sheet-carrying arms 13 are held a suitable distance apart by means of transverse pins 14 extending therethrough. Upon being rotated by the coil-spring 23 to the extreme right or by means of the pedal to the extreme left one tooth of said starwheel strikes against the foremost arm -13, and said wheel is rotated sufiiciently to move the next succeeding tooth into the space between the two foremost arms. Upon a movement of the shaft in the opposite direction the starwheel will carry to the other side the arm 43 that lies in front of it.

My invention is not restricted to the pre cise construction and arrangement of parts herein shown and described, as such construction and arrangement may be changed or modified without departing from the spirit and scope of the invention.
