To all whom it may concern: 7

Be it known that 1, JOHN DoUonnR'rY a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvanimh'ave invented new and useful Improvements in Musicspecification. v

My invention relates to new and useful improvements in music leaf turner, and has for its object to provide a device'of this character, whereby the sheet music may be readily and quickly attached thereto and securely held in place while in-use. l

A still further objectof the invention is to provide a frame or uprightin which is journaled a leaf turning arm having a spring coaoting therewith for-holding the same in different positions, further to provide means carried by the upright for supporting the cover which is also held between the jaws or a clamp secured toa portion of the frame, said frame also carryinga socket or support for attaching the device to a pianoor the like.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will Figure 1, is a front'elevation of my im-' proved music leaf turner showing its relation to a piano and illustrating the position of a sheet of music in dotted lines. Fig. 2, is a plane view thereof, "portions being broken away to clearly illustrate the construction. Fig. 3, is an enlarged perspective view of the music leaf turner, the clamps being removed and the music supports having their ends broken away for convenience of illustration.- Fig. 4, is a section at the line -f14: of Fig. 3 to illustrate the construction of the frame. Fig. 5 is an enlarged perspective view of .one 'of the members of the clamp. Fig. 6, is an enlarged sectional View of'the socket or clamp for holding the music ,leafturner upon an object. Fig. 7, is a side elevation "of'a plainly shown in Fig.

slightly modified form of my invention, portlons thereof being broken away to clearly fillustratethe construction. Fig. 8,

is a plane view thereof; and Fig. 9, is a front elevation, portions of the clampbeing broken awayto illustrate the construction. Leaf Turners, of which the following isa having an offset 3 intermediate its ends,

thereby producing a housing for certain elements of the combination. The edges of the upright are bent upon the-body as at 4,

4, and to one face of said upright at 'diflerent points throughout its length are secured a number of metallic straps 5 forming bearings 6 for the 'music lea'f turning arm 7, comprising a body or vertical portion 8, in'which is formed an offset or stop 9, a crank handle 10 and an extension 11, the end of which is coiled to form a clamp 12. The music leaf turning arm is preferably made from a piece of wire bent into shape for forming the different elements above described.

To two walls of the housing are secured the endsof-the shafts'or pivot rods 13, on

3 each of which is journaled one of the members 14 of the clamp, each of said members comprising a pair of oppositely projecting jaws 15 angular in cross section, integral curved arms 16 flat in cross section and provided with pivot holes 17, and a handle 18 U-shaped in cross section, resembling a channel iron. As before'stated these clamp members are journaled within the housing formed by the offset in the upright, and the jaws of each member are normally held in contact by springs "19, the ends of which rest the handle l8, and said springs are held '1n,place by two plates 20 mounted uponthe screiv2l, passing through the rear wall of the housing, said plates being held in position by lock nuts 22. On said screw 21 is also mounted the music support formed from a rod or wire bent'upon itself to form a pair of parallel strands 23, the central parts of which are flattened, as at 24, to form a suitable bearing for the screw 21 and the locknuts 25 which securely fasten the music support in place. Adjacent the ends of the music support the strands of wire are sep arated orcurved outward from one another as at 26 to form rests for the music' Between the rests and the extreme ends'of the music support, the strands of wire are again brought together as at 27, forming a neck and from this point the strands of wire are again separated to form a head 28 having a portion 29 lying at right angles to the body of the rod or wire, and this portion is flattened, and has secured thereon the spring clips 30, whereby the cover of the music may be held between the music support and said clamps.

On the screw 21 beyond the music support 23 is mounted a spring 31 of peculiar construction, having three indentations 32, and two raised portions orgshoulders 33 intermediate said indentations, with which the stop or offset 9 cooperates to hold the music leafturning arm in different positions.

The lower end of the frame or upright 2 carries a socket 34, a portion of which is covered with felt or other suitable material 35 for engagement with the music rack 36 or other portions of the piano or other objects, and in said socket is threaded abolt 37 the end of which is swiveled to a clamping block 38 having the face which contacts with the instrument coverd with felt or other suitable material 39, and this block may be provided with a groove or other configuration to conform withthe design of the music rack of the instrument on which the music leaf turner is to be used.

In practice the music leaf turner is secured to the piano by the socket and clamping block, and then by pressing the handles 18 of the clamp members 14 against the action of the springs 19, the jaws 15 of said members 14 will be separated to permit the insertion of the music at the fold of the latter, after which the cover may be opened and laid against the music support 23 and clamped thereto by the spring clamps 30, thus holding the music in the proper position for playing.

. The extra sheet or page is inserted between the coils of the clamp 12 of the music leaf turning arm and said arm lies back against the cover. V 7l1en the player has finished one'part and desires to turn the page, the crank handle 10 is moved from one side to the other, thus quickly turning the page and holding it in the proper position for reading, and because of the cooperation of the stop 9 with the spring 31, the music leaf turning arm will be held at either side against accidental displacement.

, In that form of my invention illustrated in Figs. 7 to 9 inclusive I provide an upright or frame 2 having an offset 3 intermediate its ends for producing a housing and the ends of said upright are bent at right angles tov form projections 40. Said projections and portions of the housing 3 form bearings for the leaf turning arms 7, each comprising a body or vertical portion 8 in which is formed an offsetor stop 9, a handle 10 and an extension 11, the end of v book.

which is coiled to form a clamp 12 When two or more leaf turning arms are used, the handles, may be made of difierent lengths, the one to'be turned first being the longer, so that when one leaf of the music is to be turned the next succeeding leaf will remain in its original position. The leaf turning arms are normally held in their positions at either side of the device by means of springs 31;the ends of which are mounted in the members 14 of the clamp, and said springs are of sufficient length to permit the clamp to open without interference, and the ends ofthe springs are bent over or headed to prevent their accidental displacement. The members 14 eachcompriso a portion of oppositely projecting jaws 15 carried by the arm 16 which is journaled in the housing by means of the shafts or pivot rods 13 and the jaws of said members 14 are normally held in contact by the spring 19 mounted in the housing 3, the ends of said spring engaging the arms 16 of each member 41 in a bolt or shaft on which is rotatably mounted the sleeve 42 carrying the cam arms 43 adapted to coact with the inside faces of the arms 16 and said cam arms are rotated by the movable handle 44 carried by the sleeve 42 and projecting through an opening 45 in one of the arms 16, said opening 45 being of sufficient size to permit the members 14 to move without interference. On one of the arms 16 is mounted an arm 46, which is stationary relative to said arm, so that by taking hold of the handles 46 and 44, the latter may be drawn toward the former, so that the cam arms 43 will be rotated to force the jaws 15 apart, for the reception of the music To each of the cams 16 is secured a music support 23, the ends of which are coiled to form clamps 12, and said music supports are adapted to engage the cover of the music book and hold said music book in an up right position. The lower end of the frame or upright 2 carries a support 34 in one portion of which is threaded a bolt 37, whereby the device may be secured to the instrument on which it is to be used. This form of my, device works in the same manner as described in the form shown in Fig. 1 with the exception that there isa greater number of music leaf turning arms, so that either one or more pages of the music book may be turned at the proper time.

Of course I do not wish to be limited to the exact details ofconstruction as herein shown as these may be varied within the 10 tions, an extension, the end of which is coiled to form a clamp and a crank handle for operating the music leaf turning arm.

In testimony whereof, I have hereunto aiiixed my signature in the presence of two subscribing witnesses.

JOHN DOUGHERTY.
