MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented Apr. 23, 1918.

Application led September 6, 1916. Serial No. 118,741.

To all whom t may concern:

Be it known that I, HENRY C. FITCH, a citizen of the United States, residing at Demos, in the county of Belmont, State of Ohio, have invented certain new and useful Improvements in Music-Leaf Turners; and 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.

The present invention is directed to iinprovements in music leaf turners, and has for its object to provide a device of this character so constructed that the same can be actuated to successively turn the music sheets.

A further object of the invention is to provide a device of this character so constructed that upon the operation of a pedal a disk will be released so as to successively7 move pins into engagement with the music leaves so that upon further rotation of the disk the leaves will be turned.

A still further object of the invention is to provide a music leaf turner so constructed that the pin actuating disk will be caused to make a half revolution under the action of a spring controlled wheel so as to successively turn the sheets of music.

Still another object of the invention is to provide a music leaf turner having means for positively separating the sheets of music so that the pins can. engage successively the same.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing in which Figure 1 is a side elevation of the device.

Fig. 2 is a top plan view.

Fig. 3 is a sectional view on line 3 3 of Fig. 2.

Fig. 4L is a sectional view on line 4 4 of Fig. 1.

Fig. 5 is an enlarged top plan view of the leaf engaging frames.

Fig. 6 is a side elevation thereof.

li ig. 'l' is a detail sectional view showing one of the pins about to be elevated.

Fig. 8 is a detail sectional view showing one of the pins in a position previous to the disengagement of the lever therefrom.

Referring to the drawing 1 designates a base, having rising therefrom a standard 2, and rotatably engaged with the standard is a disk l, having its periphery provided with rack teeth 5, the purpose of which appear later.

Supported adjacent the disk l is a gear 6, liXed to a spring actuated shaft 7 suitably journaled in the casing 8.

Supported below the disk 4 and slightly spaced therefrom .is a semi-circular track 9 having one end provided with a slot 10, for the purpose of receiving the pins 11 which serve as means for turning the sheets of music.

Pivotallv connected to the stein 2 is a lever 12, having fixed to one end the upper end of the cord 13, the lower end of said cord being attached to a pedal 14e adapted to actuate the lever- 12. Secured to the standard 2 is a sleeve 15 having a plurality of leaf engaging frames 16 carried thereby, which are provided with lugs 1S which are adapted to engage the adjacent bars of the adjacent frames to positively hold the frames in spaced relation so as to permit the pins 11 to pass therebetween so that when the disk 4 is rotating the engaged. frame will he turned as the pin engaged therewith travels along the tracks. To urge the frame 16 toward the left a spring pressed plunger.

19 is employed and is carried bv the bar 20 located adjacent the base 1, said plunger being so arranged as to engage the adj acent har of the innermost frame 16.

The disk 4t is provided near its periphery with openings 21, two of which are employed and are arranged diametrically opposite and are engaged by the pins 11 hereinbefore mentioned, said pins being slidable vertically in the openings and are provided with heads 22 which prevent the pins from dropping` through the openings.

A coil spring 21 is employed and has one end connected to the lever 12 and the other end to the base 1, said spring serving to normally hold the inner end of the lever raised while the outer end thereof is lowered. When one of the pins 11 has dropped in the opening 21 which is adjacent the rear end of the lever 12 it is obvious that it will enter the slot 10 and will engage the rear end of the lever thus holding the disk against rota tion. The other pin 11 will be engaged with the adjacent end of the track 9, and since the outer end of the lever is disposed directly ander the pin then adjacent the outer end thereof it is obvious that when the lever 12 is rocked so that its rear end will clear the lower end of the adjacent pin the forward end of the lever will move the other pin up wardly, whereupon the wheel 4 will be permitted to rotate, at which time the pin raised by the outer end of the lever will ride on the track 9 until it reaches the slot 10. By this time the pin just disengaging the slot 10 will travel until it is adjacent the outer end of the lever l2. It will be of course understood that as the pin is raised by the outer end of the lever 12 that it will engage behind one of the leaf engaging frames 16 so that said frame will be turned from the right to the left, which movement is controlled by the pedal 14.

The base 1 is mounted on a rack 23, such as a piano rack or portion of a music stand, Which supports the bar 20, and has mounted thereon a bracket 24, having mounted thereon a plate 25 which' rotatably supports the disk 26, having notches 27 formed in its periphery for successively engaging the frame 16. To tension the disk a leaf spring 28 is supported by the bracket 24 and has its inner end adapted to engage the recesses 29 formed in the under surface of the disk. As shown in Fig. 2 the outermost frame 16 is engaged in one of the notches 27, and when the disk 4 is released the frame engaged with the notch will be forced to the left, whereupon the neXt frame will engage the neXt notch,

, since the frames are urged to the left by the plunger 19. Thus it will be seen that the disk 26 serves to hold the frame 16 in proper position to be engaged by the adjacent pin 11.

What is claimed is y l. A music leaf turner comprising a base, a. stand carried thereby, a disk rotatable on said stand and having rack teeth around its periphery, means engaging said rack teeth for rotating .said disk, a plurality of leaf enga ing frames pivotally secured by said stan diametrically disposed pins supported by said disk and slidable therein, releasing means engaging one of said pins to prevent rotation of said disk and means for moving said releasing means out of the path of said pin and sliding the other pin into engagement with one of said leaf engaging frames whereby the same will be swung about its pivot when said disk rotates.

2. A music leaf turner comprising a base, a stand carried thereby, a disk rotatable on said stand and having rack teeth for rotating said disk, a plurality of leaf engaging frames pivotally secu-red by said stand, diametrically disposed pins supported by said disk and slidable therein, releasing means engaging one of said pins to prevent rotation of said disk, means for moving said releasing means out of the path of said pin and sliding the other pin into engagement with one of said leaf engaging frames whereby the same will be swung about its pivot when said disk rotates, means exerting a pressure upon said leaf engagin frames in the direction of their pivota movement, and a notched disk'the notches of which are adapted to successively engage said frames whereby to retain the same stationary against the action of the last named means until said disk is rotated.

In testimony whereof, I aix my signature, in the presence of two witnesses.

HENRY C. FITCH.
