MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented May '7, 1918.

Application filed September 12, 1916. Serial No. 119,700.

To all whom it may concern:

Be it known that'I, ToM WILLIAMS, a citizen of the United States, residing at Marysville, in the county of Marshall and State of Kansas, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

This invention relates to music leaf turners, and a the primary object, contemplates the provision of a device that can be readily associated with a foldable music rack and one whereby the sheets of music may be readily and expeditiously turned by the musician while playing his musical instru ment. 1

It is another object of this invention to provide a plurality of movable leaf holding arms With which cooperate a plurality of manually operable leaf turning arms, the latter being operable by suitable foot operating mechanism mounted on a conventional form of music rack.

It is a more specific object of this invention to provide means for adjustably mounting both the leaf turning and holding arms on a support; to provide movable catch means for automatically engaging and turning the arms; to provide resilient means for controlling the operating means for the leaf turning arms; to efliciently mount a cable about the drum for actuating purposes and to provide a portion of the support with a cam edge for facilitating the operation of the arms as well as the release of them.

A still further object of my invention resides in the provision of a device of the character described that is simple in construction, eflicient in operation and one that can be manufactured and placed on the market at a minimum cost.

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a part of this specification.

In the drawings Figure 1 is a front elevation of my invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a transverse section taken through the support tube and looking down toward the drum.

Fig. 4 is a bottom plan of the drum.

Fig. 5 is a transverse section taken.

it may be understood however, that the invention can as well be associated with a piano or of various types of supports neither of which form a material part of this invention. The support in the present instance consists of a telescopic standard composed of sections 1 and 2 the latter being adjustable within and with respect to the former in any desirable manner. A plurality of legs 3 are pivoted adjacent the upper edge of the section 1-while braces 4 are pivotally connected from points intermediate the ends of the legs 3 and the lower end of the section 1 as illustrated to advantage in the drawings. The usual rectangular support 5 is connected to the angularly bent end of the section 2 by a suitable bracket 6. Supporting brackets 7 are connected to the upper and lower edges of the support 5 at points substantially intermediate the ends thereof and extend from the outer face of the support and in parallel relation with each other while another bracket 8 is connected adjacent the lower edge of the support 5 and extends in close spaced relation with the lower bracket 7 for a purpose to be hereinafter described. A cylindrical tube 9 has stubs 10 projecting from the respective ends and journaled in the arms 7. Corrugated bands 11 and 12 arearranged about the tube 9 and have their respective ends flanged as at 13 and removably engaged by tapering slides 14. The slides 14: serve to adjustably secure the bands on the tube while the bands in turn serve to pivotally connect the angularly bent ends of the leaf holdingarms 15 and the angu larly bent ends of the leaf turning arms 16 to the tube. The outer ends of the holding arms 15 are bent upon themselves and provide spring clips 17 each adapted for engagement with a sheet of music as illustrated to advantage in Fig. '1 while the arms 16 are arranged behind a sheet of music and also bent adjacent their inner ends to .provide projections 18 as shown in Fig. 1.

In order ,to actuate the leaf turning arms I have ro-tatably mounted a drum 19 between the lower bracket 7 and the bracket 8, said drum being eccentrically mounted with respect to the mounting of the tube. Catches 20 and 21 extend laterally from diametrically opposite points on the upper periphery of the drum and at times engage projections 18 on the leaf turning arms 16. This engagement is due to the arrangement of the projections which are positioned below the plane of the arms 16 and with-in the path of movementvof the catches 20 and 21. Incidentally a portion of the lower bracket 7 is provided with a cam surface 22 adapted for cooperation with the catches and projections in a manner to be described. In imparting movement vto the drum 1 have provided a cable 23 and wrapped the same about the drum, one end of the cable being connected to a spring 24 which is in turn connected to the section 2 on the music rack. The opposite end of the cable is trained about an idler 25 and finally connected to the free end of a lever '26 pivotally mounted as at 27 to .the front leg 3. A foot lever 28 is pivoted at its inner end to the lower end of the front leg 3 while a rod 29 serves to connectthe foot lever 28 to the lever 26. When the lever 28 is depressed the lever will also be depressed thus exerting a pull on the cable against the tension of the spring, and as the lever 28 is forced farther down the tension on the spring 2% increases, and because of this frictional engagement of the cable with the drum the latter is partially rotated. The catch 20 is arranged so as to engage one of the projections 18 and swing the arm about its pivot and against the cam edge 22 so as to force the projection against the cam edge and rotate the tube 9 until the catch 20 is released.

'In order to control the movement of the drum'I provide the lower edge with two oppositely disposed recesses 30 illustrated to advantage in Fig. 4. These recesses are engageable by a spring member 31 connected to the inner end of the bracket 8 as indicated by the numeral 32. It will now be apparent that after the drum 19 has been partially rotated and the catch 20 released as has been described, the spring 31 will automatically engage one of the notches 30 to prevent the reverse movement of the [drum 19 after pressure has been relieved from the foot lever 28 which latter is returned to its former position by the spring 24:. When the sheets of music are placed in the holders and all arranged on the right, the pivoted arm 83 on the support 5 should the musician is playing his instrument. .tention 1s also ,drrectedao the peculiar co- ..operation existing between the .drum with be placed over the top sheet so as to hold the lower sheets in place while the top one is drawn from underit and turned.

The operation of my invention is as follows Assuming that the device is in a position shown in 'Fig. 1 and that the leaf turning arms are arranged to the right side of the tube 1 which consequently places the proj ections 18 in uniformly spaced-melationwvith eachother, when :the foot lever is depressed the tensionis exerted onthe spring2fl which in turn causes .a frictional engagement Alf the cable with the ldrum 19 for partially rotating thcdrum. As is apparent the catch 20 is arranged .to engage the inner of the projections 18 and during the partial rotation of the drum one :of :the .arms 16 is swung about its pivot and pressed against the cam surface 22 so as .to partially ,rotate the tube9 and bring-the next projection }in-.a position where it can ;be 'engaged by one of the catches. The first projection is forced against the cam edge ,until the catch is re leased whereupon the spring 31 will auto-- matically engage one elf-the recesses 30 and prevent reverse rotation of the drum while the lever is being automatically reset by the spring 25. The lever can now be depressed which will .cause the other .catch 21 to engage the inner of the projections 18 and this operation is successively repeated until all of the leaf gturningarms have been moved about their pivot. 1n resetting all of the ,armsit is only necessary to partially depress the foot lever and :turn them to the right by :handlingeach oneat a time .or all together.

Although Ihave show-hand described the preferred embodiment iof my inventionl desire it :to be understood that I am not to be limitedto the exact details shown. However, I desire that great stress be laid upon the arrangement ;of the device that can .be readily associated with various types of supports for turning sheets of n usic while the catches and .the leaf turning arms pivoted on the tube and having the projections engageable by the catches {for the purpose set forth.

From above description taken in connect1on w1th-the accompanying drawings, it

can easily be seen that, I have :provided :a
