,To all whom, it may concern: ,K

Be it known 'that I, GIUSEPPEv REGoNDr, a subject of the King of Italy, residing at New y Brighton, in the county ofRichmond, State claims.

This invention of New York, have invented certain new` and useful Improvements-in Music-Leaf Turners, of which the following is as peciiication.

relates to music-leaf turners.' y. W

It has for an objectrto improve. the mechanism for intermittently rotatingv a 'drum -th'a't controls the swingi' g movement of aplurality of leaf-turningarms.

A further object isto provide a devicefor holding the sheet-music to thesupport -during the turningof'the leaves, the device hav-` ing means for holding it 'away from the sheetmusic to permit lthe latter yto be introduced to and removed from the support. f

Other and still 'further objects willv appear in the following description and will be morel particularly pointed out iny the append ed In the drawings, Figure '1 is a'front eleva# tion of a piano employing -my invention. Fig. 2 is an inside view ofthe'front board of the piano with the casing supporting the drum in section, the other'parts being'in elevation. `v Fig. 3 is a horizontal section-:on the line 3 3 of Fig; 2 through thelcasing whenapof a pianofon line 3 3,l

plied to Vthe front boar Fig. 2, the other parts of the invention being shown in top plan. Fig. t is a bottomplan view of the drum and the operating-dogs on line 4 4, Fig. 2. Fig. 5 is a .section on line 5 5 of Fig- 2 Fig. 6 is a section of a piano, showing anotherembodimentof connecting the treadles to the drum-operating mechanism. Fig. 7 is a View of a music-stand with'my invention applied thereto. Figf8is"a side ele vation of the sheet-music holder; Fig.v 9 is a detached perspective of the Asheet music holder. Fig. 11 is a detail view of .one of the clips.

Referring more particularly-to the drawings, 1 indicates a series of arms all of the same length, formed ot thin material and having paper-clips 2 of lyre form slidable thereon to engage the leaves of sheet-music or the like. By making them slidable on the arms I am enabled to engage leaves of various widths.. There may be provided' any suitable number of these arms 1. In the drawing I have shown six. p idly connected to a small pinion 3, which is loosely journaled on a vertical shaft 4,.mount Fig. 10 is a detail view of the treadle.

edin a casing 5. This casing may be supported onl the rear-face of the front board of apiano directly above the sheetsmusic holder 6, as shown 1n Figs. 1 to 6, or on the rear of a case-*the pinions 3 project to the outside through an opening 7. Within the casing 5 fis j ournaled a vertical shaft 8, whichcarries a rdrum 9, provided with a plurality 'of segthe pinion's 3 and are adapted to successively engage successive pinions 3 .and rotate the same one hundred and eighty degreesto swing one of the arms 1. n

. To rotate the drum 9 in pposite directions, I provide a pair of toothed wheels 11 and 12 one above the other, the lower one,

'inusic-stand, as shown in Fig. 7 In'either 1,2, being of less diameter than the upper A one-i. e., the crown of its teeth extending to the base of the teeth ofthe upper one. The

' teeth of each wheel are the same in number as the racks on the drum, and each have one inclined face 13 and a straight or radial face 14, the inclined face 1.5 between the two teeth on each wheel being longer than the' other inclined faces. the teeth producing the first and. last rota-v tion, and 'the lengthened inclined face is to prevent any further rotation oll the drum in the saine direction after all the leatarnis have been swung in one direction, thus preventing the breaking of any parts.

l The`teeth of the wheels l11 and 12 have their inclined faces` extending in opposite directions and are engaged by a pair o i pivoted L-shaped dogs 1G and 17. Each dog has its upper end adapt-ed, when rotated in one dicause the 'drum to rotate with the dog and when rotated in the other direction to ride on an inclined face 13 to the next straight lace. The lowerl end of each dog is pivoted at 18 lo one of two arms 19, loosely journaled on the shaft 8 and having a spiral spring 20, tending to hold it in one position. Both dogs are held elevated by springs 18.

To rotate one arm from the position in which its spring 20 tends to hold it and at the same time to remove the dog on the other arm from its toothed wheel, I provide the fol* lowing means: Each arm 19 has connected to its end one end of a cable21J which after passing around a roller 28 is connected at its other end to the lower end of a vertical slide These two teeth are rection to engage a straight face 14 and lOl llO

o direction to slacken the cable.

site end of each horizontal slide 26 is con-v 22, held in an elevated position by a spring l 23. Each slide 22 is mounted on the front lwall of the piano and has a horizontal portion 23a to throw its upper end in the vertical plane of the dog Which'it is to operate, the upper ends being extended horizontally at 24 to lie over the dogs. Each cable 2l passes through an eye 25 on one end of a horizontal slide 26, which is moved by a spring 27 in the To the opponected a cable 29, which may be operated in any suitable nianner. in Fig. l i have shown each cable 29 leading to and around a i 5 pulley 30, located inside and near one end of the piano, thence downwardly to a pulley 31, located near the bottom of' the piano, and i from the pulley 3i yto and 'around a pulley 32, llocated near the middle of the piano. The zo cable is then connected with a treadle 33.

in the embodiment shown in Fig. 6 each cable 29 leads to the upper end of abell crank lever 34, pivoted on the inside oi the end wall of the piano'. To the other end oi 2 5 each bell-crank lever 34 is connected a recip rocating rod 35, which is connected by a pivoted lever to a treadle 36.

It is obvious that as soon as either cable 29 is pulled by depressing one of the treadles of 3o either embodiment a slide 26 will cause both ends of one cable 21 to be pulled, and as this cable is connected to both dogs 16 and 17 one dog will be pulled out of engagement with its toothed wheel and the other dog will be 5 5 caused to swing and rotate the drum 9 in one If the other cable 29 is pulled, a-

direction. reverse rotation of the drum 9 will taire place. The dog causing the rotation moves the drinn the distance of one of the racks 1'0 only. 4o Of course when the drum is rotated in one direction the leaf-'arms 1 svafing in one direction, and vice versa.

in Fig. 7 i have shown my invention applied to 'a music-stand. in this embodiment the cables 29 lead from the treadles 33 to the slides 26, arranged on the back of thestand in the same manner as in the other embodiment.

l'lfhe treadles may be formed in any suit able manner; but i prefer to construct them as shown in Fig. 10.

A pair of side` members 37, each formed of a strip of metal bent 'upwardly upon itself, as

at 38, to forni a bearing for a shatt 39, carrying the foot-piece, is provided, the side mem- I bers being provided with eyes 40 at their end, by which tney are secured in place, and being connected together by a bar 41, on which roller 32 is jonrnaled.

To hold the music while the leaves are be ing turned, and -thus to prevent their being thrown to the iioor during the operation of the turner, i provide the device shown in detailin Figs. 8 and 9. It com rises a thin 55 flexible arm 41', adapted to t etween the leaves at the point of their connection, and which is normally pressed against the sheets of music. The arm 41 is carried by a block 42, pivoted at 43 between two arms el on a plate 45, which is attached to the rear face of l7o the front board of the piano or to the rear 'face of the music-stand, the support Llbeing slotted or out away at 47 to permit the free movement of the arm to and from the sheetmusic. To hold the arm against the sheetmusic, ,a coil-spring 4S is provided and abuts at one end' against a shoulder 49 on the block 42 and at its other end against a shoulder 50 `onplate 45, projections 51 entering the ends of the spring and holding it against lateral displacement.

The arm 41" is held away fron'i the sheet music by providing a laterally-swinging portion52, which is in the form of a knob pivot'ed at 53 and adapted to be thrown into a notch 54 on one of the arms 44 on the attaching-plate 45 when the arm 41 out of en gagement with the sheet-music, as shown in dotted lines in Fig. $4.
