MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented Feb. 4:, 1919.

Application filed April 10, 1917. Serial No. 160,988.

To all whom it may concern:

Be it known that I, CURTIS STRAW, a citizen of the United States, residing at Harpster, in the county of Wyandot, State of Ohio, have invented certain new and useful Improvements in Music-Leaf Turners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in devices for turning sheets of music or the like, and has for its primary object to provide a device of this character in which several sheets of music may be successively turned at the will of the operator.

A further object of the invention is to provide a device of this character in which after the operation has been completed, the same may be,reset to repeat the leaf turning operation.

Referring to the drawings,

Figure 1, is a perspective view of a music stand with the leaf turning attachment in place thereon,

Fig. 2, is a sectional view of a portion of the device,

Fig. 3, is a detailed view of one of the leaf turning elements,

Fig. i, is a vertical sectional view of the cylinder, showing the rings of the leaf turning element in position therein,

Fig. 5 is a plan view showing diagrammatically the rings of the leaf turning element and the same positioned in their different steps of movement.

Fig. 6, is a detailed view of a portion of the operating mechanism; and,

Fig. 7, is a detailed view; and,

Fig. 8, is a detailed view of a portion of the cylinder showing the method of supporting the leaf turning elements therein.

Referring more partlcularly to the drawings, the reference character 10 designates a music stand, the vertical extending standard of which is preferably tubular in form. Secured to the upper end of the tubular member 11 is a cylinder 12 which is cut away as at 13 to provide a space or opening which latter extends throughout one-third of the diameter of the said cylinder 12.

The inner walls of the cylinder 12 are provided with shelves or projections 14:, and resting on said shelves or projections 14 are rings or the like 15 to each of which is rigidly secured an arm 16 which projects through the open portion 13 of the cylinder 12. These arms 16 are jointed as at 17 and 18 in order that they may be folded to 00- cupy a small amount of space, and on their free ends, each of said arms is provided with a leaf engaging clip 19. Extending through the tubular member 11 is a shaft 20, the lower end of which is provided with a gear 21, and mounted in a bracket 22 is a ratchet member 23 which is provided with ratchet teeth 24 on its periphery, and a beveled gear 25 on one of its side faces, which beveled gear 25 is adapted to mesh with the gear 21 on the lower end of the shaft 20. As shown in Fig. 7, a foot lever 26 is pivoted to said bracket as at 27 and is adapted to depress against the action of a coiled spring 28 which in turn is secured at one end to an arm 29 and at the other end to said lever. Pivoted to the lever is a dog or pawl 30 which is adapted to engage the ratchet teeth and rotate the gear 23 upon depression of the foot lever 26. The upper end of the shaft 20 is provided with a right angular member 31 which is slidably mounted thereon and is adapted to move upon rotation of the shaft 20.

By reference to the diagrammatic view it will be seen that each of the aforementioned rings is provided with notches 32 in its in ner periphery and it is these notches with which the right angular member 31 is adapted to engage to rotate the rings, thus moving the leaf turning arms 16 from right to left to turn the sheet of music to which each of said arms is connected. For the sake of convenience in describing, each of the rings shown in the diagrammatic view will be given a different character, and as seen-in this figure the ring A is provided with two notches 32 and 32 the right angular member 31 being engaged in the notch 32 With the parts in this position, when the foot lever 26 is depressed, the right angular member 31 is moved to the position shown at the right of said figure, thus turning the ring and moving the arm connected thereto from the extreme right to the left to turn the leaf of music. When the parts are in this position, the notch 32 nvill be in register with the notch 33 in the ring B, thus permitting the right angular member 31 to drop out of engagement with the notch 32% in the ring A into engagement with the notch 33 in the ring B.

Upon another operation of the foot lever 26',

the ring B is turned to the position shown at the right in this figure, and the notch 33 of the ring B is then in register with the notch 32 in the ring A and the notch 33 with which the right angular member 31 is engaged is positioned over the notch 23% in the ring C, and said right angular member 31 then drops into the notch 34 of the ring. C. By another operation of the foot lever 26 the ring O is rotated, whereupon its notch. 34 moves into. al-inement with the notch 32 of the ring A and 33 of the ring 13. If now it 'be desired to reset the music turning arms 16, the foot pedal 450 which is pivoted as at 4:1 to a. bracket @21 is depressed, and moves a rod 43 vertically,

which rod is formedwith av collar 4A. loosely embracing, the shaft 20 to engage the arm 31 at the under face thereof for raising the. same, and upon elevating this rod it. will be seen that when the slots 32 33 and 34 are in registration with each other, the member 31 is permitted. to pass upwardly through the rings A, B, and C, until it is disengaged with the top ring A, whereupon the arms connected to the rings A,.B, andC are free to be moved from the. left to the right to againposition them in order that they may turn the music from. the right to the left during. the. playing operation.

By this mechanism it is apparent that any number of leaf turning arms may be employed, since the operating member will engage in the notch of each. succeeding ring as the operation of. the ring. with which it is engaged is completed. It is also apparent that at any time during. the operation ot the device the same is capable of being reset for subsequent operations in a manner previously described. v

- As shown in Fig. 6, the member 31 is provided with a circular portion 40" and. said circularv portion is provided with oppositely disposed recesses 1 which are adaptedLto receive oppositely disposed longitudinal ribs on the shaft 20. By this construction it will Copies of this'patent maybe obtained for be seen that the right angular member 31 is free to move longitudinally of the shaft 20 but at the" sametime, is caused to rotate therewith.

Hay mg thus described the invention, what is claimed, is:

1. A music leaf turner comprising a support. having, a cylindrical head formed with an opening in its front, a plurality of superposed shelves within the head, rotatable rings. supported on the shelvesand having notches, a rotatable shaft journaled in the support, a vertically movablearm slidably fitted on: the shaft and rotatably therewith and successizvely engageable in the notches in said: rings, means on. the support for raising and: lowering the arm, music leaf turning. members carriedby the respective rings and working throughthe open front of the cyllndrical head, and means onv the support for imparting intermittent movement to the shaft.

2. A music leaf-turner comprising, a support having a cylindrical head formed. with an opening in its front, a plurality of. perposed shelves within the head, rotatable rings. supported on. the shelares and. having notche's, a rotatable shaft journaled. the support, a vertically movable armsl-idably fitted. on the shaft and rotatably therewith and successively engageable in the notches in said rings, means on the support for raising and lowering the arm, music leaf turning members. carried. by; the resp'ectiye rings and working through the openfront of; the cylindrical head, meshing gears. carried by the shaft and support, and a foottreadle pivoted to the support. and. having ratchet connection with one ofthe gears for imparting intermittent movement thereto.

In testimony whereof, aflixmy signature in the presence of two witnesses...
