MUSIC-LEAF TURNER.

Specification of Letters Patent.

, Patented Dec. 24, 191s.

Application filed August 13, 1917. Serial No. 186,002.

To all whom it may concern:

Be it known that I, CLAUDEHURN, a citizen of the United States, residing at Centralia, in the county of Lewis, State of Washington, 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 music leaf turners.

One object of the present invention is to provide a device of this character which is simple in construction and durable and effective in operation.

Another object is to provide a device of this character wherein the player need not use his hands or feet to turn the music leaves, thus relieving him of removing his hands from the keys of the piano or organ, and his feet from the pedals. 1

Another object is to provide a novel and effective means for turning the music leaves first in one direction and then in the other.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a front elevation of my im proved music leaf turner shown in connection with the music rest and front board of a piano.

Fig. 2 is a top plan view of the same.

Fig. 3 is a side elevation of the same.

Fig. dis a vertical sectional view taken on the line 4-4 of Fig. 1.

Fig. 5 is a horizontal sectional view on the line 5-5 of Fig. 1.

Fig. 6 is a horizontal sectional view taken on the line 6-6 of F ig. 1.

Fig. 7 is an enlarged vertical sectional taken view taken on the line 77 of Fig. 1.

Fig. 8 is a perspective view of one of the knee levers.

Fig. 9 is an enlarged vertical sectional view taken on the line 99 of Fig. 1.

Referring particularly to the accom anying drawing 10 represents the front card of the piano, llthe movable music board, and 12 the music ledge carried by the piano below and in front of the board 10.

Disposed against the music board 10 is a base board 13 ofthe leaf turning device. Through the board, adjacent each of the four corners, there is formed an opening 14.,

"and throu h this opening is disposed the stem 15 o .a clamp 'member. This clamp member-includes the block-.16. and the stem 15, before-mentioned, said stem'being externally threaded and receiving thereon the clamping nut 10""for holding the. block on the board, and the slidable hook rod 17 adjustable through the block by means of the set screw 18. The upper hooks engage over the upper edge .of the frontv board of the piano, or the upper edge of the music board 11, while the lower hook members engage under the lower edge. thereof. These hook members are provided with felt. linin s 19 for the purpose ofprotecting the polished surface of the piano. By reason of the adjustable features of the clamps it is readily seen that the base board of the device is capable of attachment to pianos of different designs and sizes.

Carried by the lower central portion of the outer face of the base board is a bracket 20, and carried by the central portion of the upper end of the board is a bracket 21. The upper bracket extends upwardly above the board, and thence outwardly, as clearly shown, while the lower bracket extends out wardly from the face of the board. Disposed vertically through these brackets, and in front of the board, is a shaft 22, the upper end of which is bent laterally to the right beyond -theboard, as at 23, while the lower end is bent laterally to the right and beyond the board, as at 24. Each of these portions 23 and 21 is provided with the leaf engaging clips 25, which gri the top and bottom edges of the leaf to be turned. 7 I 3 Loosely rotatable on theupper and lower portions of the shaft 22 are the tubular shafts 26 and 27, each having on one end a pinion 28, that on the former bein on the lower end while that on the latter. 1s on the upper end. Adjustable 0n the shaft 22 are the stop collars29 whichserve to hold the tubular shafts in proper position on the shaft 22. The upper end of the shaft 26 is providedwith a laterallyv and .npwardly turned arm 130 which normally'; extends to:- ward the left, while the lowerend of the shaft 27 is formed with an arin which extends laterally toward the' right-and thence downwardly, as shown at 31. The. upwardly extending portion of the arm 30 is arranged while the'low'er a111r31'i's arranged to engage and move the lower arm.=2t. In the firstinstance the leaf arms are turned 'to the ,right, while inthe 'o'ther instance the arms are turnedto'the left. 1

Extending through the base board adjacent the pinion of the upper shaft 26 is a shaft 32- on th'e outer end of" which there is mounted a 'se mentahgear 33 engaging with .the pinion onthe'sha'ft; On thelo'w'e'r por- {tion of the bo'a'rd'; adjacent the pinion 'of the shaft 27 is a similar shaft 34: having a seglnent'al pinion" was its ease-1* end engaging with the pinion of the shaft-l 27'. The other end ofv-tfhe shaft 32'-'isprovided with an arm a tofthe oiite'r endf o f which isc'onnected one endfof aeord or wages, while acord' or wire 37 is'co'nne'ctedtoone end of'asimilar arm "38; 'onlftlife shaft Sai Thesewires extend up; wardly over ig-rooved wheels or pulleys 39' mounted on the" inner face of the upper aria we ga e muse ta te" or ,'thepiano.

-Mounted withinthe piano, 'inwardly of the {some boardthereof, and'inline with'the bottomfaee of lower 'boa'rd the key rest era's piano, are-pulleys fO ai-ound which "the wires pass, v The 'wire'spass' through the front "ofthe piano wherethey are connected to the "laterally'"extending arms 41 of'the knee engagin 1members 42) Th'eseme'mbers 42 are-pivotall-y' mounted in brackets 43 carried by the bottom board ofthe key rest, and have the I outwardly j extending blades 4% fwhich are arranged to be pushed sidewise by the knees of the'playe'r to draw the wires and'eause the rocking of the segmental pinions. ",The' movement of either" of these pinions turns the engaged pinion'of the tu bular shaft and by reason of'the engagement of the' armon's'a'id shaftthe'leaf arm will be swung to one side and the leaf be turned.

"connec d to .e c esm r iblfmal-ly" hold is on n Qfia" a l i s as a spring b lllgf tlle pinion, 'res1liently,;in pos tion; for actuatlonfijand returning the same to its normal or initial position,-

Itwill be notedjthajt' the up er Pinion 33 'arranged to turn the shaft 26 toward the right, while the pinionfB l is arranged to "turn-"the: shaft??? toward the, left; Thus I when'the'player desires to'tu rn the leaf to- 'j'ward'the left he simplyoip res'ses; the right blade with his rightjlrneewhich results in the wlre' connected thereto'pulli'ng the pinion i be restored to its initial position at the right handside of the board. When the leaf is to be turned back to its original position, that is at the right "hand side of the board, the

left knee of the player is pressed against the other blade 44, with the result that the upper tubular shaft will be turned by the upper pinion 3'3, and the arm at theupper end of the shaft 26 moved to engage and swing the upper arm of the leaf holding member.

Thus the leaf is restored to position to be again turned when desiredby the player.
