To all whom t may concern.'

Be it known that I, ERNST BEER, a citizen of the United States, residing at Saratoga Springs, in the'y county vof Saratoga and State of New York, have invented certain new and useful Improvements in Leaf-Turning Devices; 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 improvements in what are generally termed leaf turners, more especially for sheet music for pianos or stands. Y

It has for its object to provide for the ready turning of the sheets of music without the direct interposition of the hand or its contact with the sheets.

A further object is to carry out these ends with facility and expedition and to provide an inexpensive and simple device for its intended purpose.

The invention consists of certain instrumentalities yand Jfeatures of construction substantially as hereinafter more fully disclosed and particularly defined by the appended claims.

In the accompanying drawings is illustrated the preferred embodimentof my invention wherein it will be understood that various changes and modifications as relate to the detailed construction and arrangement of parts may be made without departing from the spirit or scope of the invention asembraced in the claims.

In the drawings:

Figure 1 is a front elevation of my invention, partly in section.

Fig. 2 is an end elevation thereof.

Fig. 3 is a detailed end view thereof, showing more particularly the means providing for the release of the spring-containing casings in allowing of the shifting of the leaf turner.

Fig. 4 is a plan view of my invention. Fig. 5 is a horizontal section thereof, taken just abovethe lower spring containing cas- Iig. 6 is a fragmental perspective view on a somewhat enlarged scale showing more fully certain parts of Fig. 3.

Figs. 7, 8, 9, l0, 1l and l2 are further de tail views, 1n plan andsection further dis-- closing the elements of Fig. 3 more particua larly as to the different positions assumed thereby during the operation of the machine.

Figs. 13, 14 and l5 represent a side elevation, a front elevation and a plan view of my invention as applied for use with respect to a stand.

Incarrying out my invention, I employ or provide what may be termed a bracket or carrier 1, preferably consisting of a transverse member and opposite end members at right-angles to the latter, preferably in a single structure. The transverse member has inserted centrally therethrough the nutequipped end of a preferably bolt-like or pin member 2, this being rigidly secured thereto, and upon the latter member is sleeved a bushing 8, one end of the pin or bolt-member being preferably flanged or enlarged, the resultant enlargement being angular and let into a corresponding recess or socket in one end of said bushing for the retention of said pin 2. The opposite end of said bushing is laterally extended, the resultant extension being cogged or toothed, thus forming a gear or pinion 3a which is intermeshed with a small gear or pinion 4 for winding or putting under tension a spring 5, suitably connected to the bushing 3 and to a casing 6 carried upon a shoulder of the bushing, as required in moving or turning the leaf-turner with the desired music sheet or sheets, in one direction as vpresently more clearly seen.

Similarly a second spring 7 is housed in a second casing 8 carried upon a shoulder of a bushing 9 having a cogged or toothed eX- tension forming a gear or pinion 10 which intermeshes with a pinion or gear 11 for winding or putting under tension the second spring 7, as required in moving the leafturner, with the desired music-sheet or sheets, oppositely to the direction in which the aforesaid leaf-turner is turned or moved, as may become necessary. The

gearings

4 and 11 have their shafts 4a and l1, respectively, suitably journaled in the carrier 1 and arranged to be readily actuated by hand; also said gearings are held against reverse movement by means of pawls or detents 4b, 4c pivote'd upon the carrier l and engaging said gearing, respectively. A spacing tubular member 4d sleeved upon the bushing 3 is interposed between, and retains the

casings

6 and 8 in position with spect to the other parts of the device. Suitable rotary bearing members or balls 8a, are

interposed between the spring-containing casings and the general inclosing therefor 1n order to reduce Vfriction and for` the smooth movement of said casings.

The leaformusic-sheet turner12, only one being shown,'it being understood that any number may be used, includes principallya preferably L-shaped member 12l and fa hand actuated member 12b, said members 12a, 12b` beingadapted to be vapplied soas to be moved horizontally in an arcuate plane to the pin vor bolt-like member 2, and to a preferably'laterally eXtendedV headed screw 13 threaded into the lower end of said pin,`

conveniently provide for the accommodation of the vdevice for playing from a book in stead of from sheet-music, is suitably fixed to the carrier 1, the adjustment between the Aframe and rack being effected preferably by means of keeper or loop terminals 15'UL on said rack, receiving the side members of said frame, and set screws 16a working in said loop-terminals and engaging the frame side members, as clearly shown in Fig. 1. f

Suitable stopping'slidesor members V17, 17 a are provided, two upon eachfspring-containing casingfY and 8, so arranged that lby their cooperation with other parts or instrumentalities presently referred to, they will restrict the'movement-of each casing to a predetermined arc in `effecting the actuation of theleaf er sheet turner asmore fully disclosed hereinafter.

Levers 18, 18X are oppositely fulcrumed, with respect to the carrier 1 and the VspringL containing casings6, 8, upon a rod or shaft Vr18a `supported ingthe carrier, and arranged Vfor cooperation withY the stopping slides or members 17 as presently seen vand for reverse actuation, as also presentlyseen. The levers 18, 18.X Iare connectedpreferably by wires 18h, say three-sixteenths of aninch gage, to opposite levers 19 suitably fulcrumeid just `above the present music'sheet rest of pianos, said levers 19 being provided each with whatmay-be termed as a' hanger 20, having a button-hole like terminal 21 to vprovide for indicatingwhich leaf to turn.

. The spring-casings are provided with pins or .plungers 22a, 22X adapted t0 be engaged respectively -by the levers 18, 18X Aat one end of each, as will be apparent Yfrom Figs. 3,

4and 5a. T hepins orplungers are prefer- Y ably reduced at vreversed opposite ends for actuation by the levers 18, 18X. The reduced V.ends of saidpins are passed through apertures in-the bottoms of the Spring-.containing casings to extend therebelow for engagement with the leafor sheet turner to cause the latter to travel a predetermined distance, or one half way around. Springs 23, 23'are applied to the pins or plungers for automatic retention in initiall position-and automatic relaxation, or disengaging movement, -when pressure is removed therefrom. Zhen the pins or plungers 22a, 22X are de,- pressed or acted upon by the levers 18, 18X, which, as before stated, allow ofthe required movement of the leaf or sheet turner,

Vspring-pressed levers 24, 24'LL suitably pivlevers 24, the parts thus resuming their initial position for a subsequent like operation when the leaf or sheet turner is to'be again brought into action.

In Figs. 13, 14, and 15, is shown the application of my leaf orsheet turner to a

music sheet stand

25, 25a designating the -support lso orupright thereof,l the 4stability of which Y in upright positionV depending upon the tripod or feet 26. Flexible connections lor members 27 are providedv between pedalequipped levers 27X, pivoted upon said feet or tripod, and levers 18XX 'corresponding to the levers 18, 18X above referred te, said elements having associated therewith, as suggested by the foregoing .primary .embodiment of the invention, a ycarrier orv bracket 528C, and in practice cooperating parts as'alsoV setforth therein, and a rod 18m-.corresponding to the rodl 18a and supported by the carrier 28, said rod 18C@- for-ming the pivot for the lever 18m. The flexible connections 27 and .the standfsupport'25 have adjustably applied thereto, as at 29, means similar to E15, 16, 16a.V of the "primary disclosure and for the application of a frame and rack thereto.

VF rom the foregoing description andillusf tration as kexemplified bythe accompanying drawings, it is believed that the'advantages and facilities of my invention have been fily disclosed and made readily appreciae.`
