This invention relates to new and useful improvements in. music leaf turner-s, and particularly to turners which are associated with music stands. j I '5' One object of the invention is to provide a device of this character which is simple in construction,and which may be easily folded, to occupy a-small space, when not in use.

Another object is to provide a device of this '10 character which includes novehmeans for holding those portions and leaves of a book which are to be turned, thus leaving the remainder of the leaves free to be turned.

Another object is to provide a device of this character which is equipped with novel means whereby the music supporting portion of the stand may be firmly clamped on the music shelf or ledge of a piano.

A further object is to provide a device of i this character which includes means for maintaining the rack in proper position against the backboard of the music ledge of a piano.

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

In the drawings:

Figure 1 is a front elevation of the device as applied to the music ledge of a piano.

Figure 2 is a vertical sectional detail view on the line 22 of Figure 1.

Figure 3 is a front elevation ofthe device in folded position.

Figure 4 is a vertical sectional view on the line 44 of Figure 1.

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

Referring to the accompanying drawings, there is shown a music rack which includes the central upwardly extending fiat strip 10, to the opposite sides of which are pivotally connected the music ledge members 11, and the laterally extending braces 12. The braces 12 are formed with longitudinal slots 13, which receive therethrough the bolts 14, carried by the intermediate portions of the central strip 10, whereby said braces may be slid inwardly and outwardly, for the purpose of adjusting the rack for music pages of different widths. In the outer endof each of the braces 12 there is formed a longitudr n-al slot 15, and disposed through the slot, and through the vertical sidebar 16, of the rack, as well as through the outer end of'the brace arm 17, which has its other end'pivotally connected to the central strip 10, is a pivotmember '18. The bolt 14 is provided with the winged nut 19, by means of which the arms 12 may be held intheir adjusted positions. Slidable longitudinally on the outer portion of each of the braces 12 is a sleeve 20, which is provided with a fingerpiece 21, for cooperation with the finger-piece of the pivoted spring pressed jaw 22. This jaw has a transverse-bar 23, on its outer end, for cooperation with the brace 12, to clamp those pages of a book of music, which are not tube/turned by the device, the sleeve being arranged to be moved on the brace to ac-- commodate books, or sheet music of different widths, as will be clearly understood.

To fold the rack portion of the stand, the operator grasps the music ledge members and swings then upwardly until they lie in superimposed relation to the central strip 10. The upward movement of the members 11 draws the brace arms 17 upwardly, also, and at the same time swings the vertical sidebars 16 into close relation to the members 11 and the strip 10, so that the said bars extend in an upward-direction. I

Mounted on the upper and lower portions ofthe-rearface of the central strip 10 are the members '24, each having a plurality of vertically disposed tubular sockets 25. Disposed in each of the tubular sockets '25 is the vertical arm of a right-angular wiremember 26, the other arm extending in parallel relation to the music ledge members of the rack, as clearly seen inFigure 1, of the drawings. T elescoped on the other arms of the members 26 are the tubular members 27, a flat strip 28 having its upper and lower ends secured to the other ends of an upperand lower tubular member, whereby to providea'. rectangular leafturning frame. These frames are adapted to be turned by any well known means, which it is not thought necessary'to illustrate. Carried by the flat-strip 28 are the spring clips 29, which are adapted to grip the outer vertical edge of a music page.

' When the rack is to be folded, the frames These clamps serve to hold the; music rack 28 -26 are removed therefrom, by withdrawing the tubular members 27 from the members 26,: and then slipping the members 26 from the tubular socke'ts25.

Secured to the lower face of each of the music ledge members llis a spring jaw clamp.

portion of the music stand, when'removed from the floor supporting portion, whereby to adapt the device for turning thepages of music for a performer, at the piano. To serve as'an additional strengthenmgmeans for the device, when used onthe music rack of a piano, there is provided a vertical member 31, which has areducedeild. engaged in a socket member-32, carried by the rear face ofthe, central strip 10. The me1nber31 extends upwardly beyond the upper end of the strip 10,, and has the soft material attached thereto on the face which engages the back-board of the music rack ofthepiano. Mounted on the forward face of the strip 10,ad 'acent the upper. and lower endsthereof, are the outstanding brackets 32, each formed with an opening 33 for the reception of the upper and lower'ends of the wire rod 34. The intermediate portion of said rod 34 carries a small clip 35 which is adapted to receive and hold the inner edges of the innerloose leaf of a piece of sheet music, thereby serving as the hingefor such leaf.

As seen in Figure 2, the rear face of the strip. or member 10 isprovided with a loop 36 which is adapted to receive the upper flat end of the stem of the ordinary floor stand of a music rack, when such rack is to be used by the player of some instrument other than the piano.

t While I have illustrated the arms12 ends of the ledge members and each having a pivot member intermediate its ends engaged in the outer end of a brace arm,each of said lateral arms being slidably; I engaged with one ofsaid pivots, leafiturning frames supported on said central member, and a grip- .j acent the ledge members and having its other ping jaw slidably adjustable on. each of the lateral arms for cooperation with said arm vfor grippingand holding pages notto be turned. t

2. A foldable music leaf turning rack including a vertical central member, ledge members pivotally mountedon the central member, lateral arms slida-bly and pivotally connected to opposite sides of the central member, vertical members pivotally connected with the outer ends of the ledge members and each having a pivot member intermediate its ends, brace, arms each pivotally connected at one ,end with the central member ad- I endconnected with the pivot of said verticalmembenthe outer ends of the lateral arms being slotted to receive said pivot members, leaf turning frames removabl. mounted on the central member, and a lea gripping clip slidably supported on each lateral arm having a transverse member cooperating with said arm to retain pages of music not to be be turned. 9 v

In testimony whereof, I aflix my signature.
