C. JENNER musxc LEAF TURNER Filed April 1924 Patented Dec. 16, 1924.

PATENT oFFIcE.

CHARLES JENNER, OF GQRVALLZS, OREGON.

e Music-Lean TURNER.

Application filed April 2,

To all whom it may concern:

Be it known that CHAnLns JENNER, a citizen of the United States, residing at Gorvallis, in the county of Benton and State of Oregon, has invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

This invention is in the way of a music leaf turner, and the object is to provide a simple, eflicient and practicable device of the kind which may be positioned on the piano or music stand and will operate to turn the leaves one at a time.

A further object is to provide a simple mechanism capable of being operated by the touch of a finger, which will at each touch release a leaf-turning finger and turn a leaf of music.

In the drawing- Figure 1 is a frontal elevation of the device;

Figure 2 is a top plan View;

Figure 3 is aside or ed e view;

Figure 1 is an enlarged detail of the hinged spring set mountings of the several leaf-turning fingers.

This invention consists of a suitable back frame 1 upon which are mounted spaced music sheet rests or stops 2, spaced apart as shown at 3, and which support the music sheet or book in position. A. small central rod 1 is vertically mounted upon the frame 1, and spaced slightly therefrom by means of the studs 5. A number of angular spring set leaf-turning fingers 614, 7--15 and 816, preferably constructed of single pieces of wire, have their

lower stems

6, 7, and 8, aligned along and perpendicular to the central rod 3 and are looped thereto at 9, one above the other, while the upper stems 1-1, 15 and 16, stand vertically side by side. These fingers are thus adapted to turn from right to left, one after the other, succ ssively. Coil sprin s 10 normally tend to throw these lingers over towards the left side of the frame 1. The said leaf-turning lingers 6-14, 7-15 and 8-16 are formed with downwardly

bent knuckles

11, 12 and 13 at the junctures of the vertical and horizontal stems, which knuckles fall successively one below the other in stepped relation. The upwardly extended

stems

14, 1 and 16 are all aligned with the rod l of the device. The stems 1%, 15 and 16 are adapted to set or fall within the spaces between the stops 18-24. Seria1 No. 703,582.

2 when the fingers 6-141, 715 and 8-16 are turned to the right or left, so as to provide a means for inserting the stems 1 1, 15 and 16 back of the respective leaves of the music while the music rests upon the said stops 2. A spring set release rod 17 having a thumb piece 18 formed upon its outer end is pivotally mounted at 19 to the central rod 4: and extends laterally therefrom, and across the right side of the frame 1. The portion 20 of the release rod 17 is adapted to freely cover the

stepped knuckles

11, 12 and 13 of the turningfingers 614e, 715 and 816. k rack 21 is secured at 22 to the lower right corner of the frame 1 and is adapted to engage the end 23 of the release rod 17, and a stop bar 24Lholds the end 23 in free engagement with the rack 21. By first inserting the prongs 1'1, 15 and 16 back of the respective leaves of the music which is positioned upon the stops 2 and then pressing the

fingers

6, 7 and 8 all over to the right and locking them with the release rod 17 which covers the

stepped knuckles

11, 12 and 13 as shown in Figure 1, the leaves may be readily released and turned one at time by merely pressing downward on the thumb piece 18. Of course, any required number of leaf-turning fingers may be mounted upon the frame.

While I have herein described a certain specific method of constructing and assembling the elements of my invention, it is understood same may be varied in minor details, not departing from the spirit of my invention as defined in the appended claim.

I claim:

A music leaf turner of the kind described, comprising a back frame; spaced music sheet rests mounted upon the back frame in horizontal alignment; a central rod vertically mounted upon the back frame and spaced slightly away therefrom; a number of angular leafturning fingers 11)1'f612tl)ly constructed of single pieces of wire having their lower stems spring set to the central rod, one above the other, their upper stems disposed yertically side by side, and adapted to normally turn from right to left, said fingers being provided with downwardly bent knuckles at the junctures of their upper ant lower stems, which knuckles full successive-- ly one below the other in stepped relation: a spring set release rod pivoted to the central rod and extended laterally to cover the said knuckles of the said fingers and having In testimony whereof I affix my signaa thumb P1606 on lts outer end; a rack ture. mounted upon the lower lught corner of the 4 T T 4 frame to engage the release rod, and lock CHARLES JLBBER same 111 suceesslve posltlons; and a release lVltnessesz rod stop to hold the release rod 1n free en- E.
