MUSIC-LEAF TURNER.

:PIEGIFIGATION forming part of Letters Patent No. 738,298, dated September 8, 1903. 1

Application ma April 2, 1903. Serial 110.150.2201. (N model.)

To all whom zitmmg concern:

Beit known that I, ALFRED D. CRIST, a citizen of the United States, residing at Vanwert, in the county of Van lVert and State of Ohio, have invented a new and useful Music-Leaf Turner, of which the following is a specification.

This invention relates to devices for turning the leaves or sheets of music, whereby the hands of the performer are left free to manipulate the instrument.

The object of the invention is to simplify and improve devices of this character and to increase their efficiency without increased expense or complication of parts and to provide a device which may be placed on an ordinary music-rack of any kind.

The invention consists in certain novel features of the construction as hereinafter shown and described, and specified in the claim.

In the drawings illustrative of the invention in which corresponding parts are denoted by like designating characters, Figure 1 is a front elevation of the improved apparatus. Fig. 2 is an end elevation. Fig. is a bottom plan view with the cover of the spring-easing removed. Fig. l is a transverse section of the sheet-clamp on the line 4 a of Fig. 1. Fig. 5 is a perspective view of the outer end of one of the swinging arms. Fig. 6 is a transverse sectionon the line 6 6 of Fig. 1. Fig. '7 is a detail, partiallyin section, of the trip mechanism. Fig. 8 is a detail of the casing-supporting stud.

The improved device may be attached to the music-rack of a piano, organ, or other musical instrument having music-racks attached or to portable music stands or easels, and for the purpose of illustration a section of a conventional form of an ordinarymusicrack is indicated at 10, upon the shelf of which the improved device rests.

The improved device consists of a supportin g-frame or back plate 12, resting by its lower end upon the shelf of the music-rack of the instrument and having a supplemental shelf 13 for the music, either in sheet or book form, as will be obvious.

The shelf 13 is provided with a stop 14, extending longitudinally thereof and serving to hold the lower edges of the music away from the plate 12 in position to be engaged by the operating arms or fingers.

Attached in a vertical position centrally of the back plate 12 is the stationary member 15 of a clamp device for holding the back edges of sheetmusic, the movable jaw member being shown at 16 and movably connected to the stationary jaw, as by pivot-pins 17, and supported in yieldable position relative to the stationary jaw by springs 18. The movable j aw 16 is provided with a thumb-plate 19, ex tending laterally therefrom and by which it is operative, and the stationary jaw 15 is provided with an extension or foot 20, by which it is secured to the plate 12, as by screws or other means. The foot-plate 20 is provided with an elongated aperture 21, having one end enlarged, as at 22, and with a lateral offset 23 at the opposite end, the offset being the same width as the body of the aperture, as shown.

Movably connected, as by pivot 24, to the foot member 20 is a hook 25, having its recess 26 adapted to register with the offset 23 when closed. Extending from the rack 10 is a stud 27, having an enlarged head 28, the head corresponding to'the larger portion 22 of the aperture, and the body 27 of the stud corresponding to the body of the aperture and the offset 23. By this simple arrangement it will be obvious that by passing the enlarged end 22 over the head28 of the stud and moving the plate 12 and its attachments downward and then laterally to cause the shank of the stud to enter the offset 23and closing the hook 25, with its recess 26, over the shank and behind the head 28 the improved device will be firmly and quickly locked to the rack 10, but easily releasable therefrom by simply opening the hook 25.

Attached to the plate 12, at opposite sides of the clamp member 15 16, are horizontal bars 29 30, extending beyond the plate and provided with slidable clips 31 32, the bars providing supports for the music-sheets or musicbooks and the clipsadapted to engage the covers of the books and hold them open. The clips will also be convenient for holding the first and last leaves of the sheet-music, if required. The bars 29 30 will preferably be located in a line intermediate of the ends of the clamp means15 16 and will be provided with upwardly-extending wire supports 11 for the upper parts of the music-sheets and in substantial vertical alinement with the outer faces of the bars.

The stop 14 will be provided with a vertical central cavity 33 in alinement with the clamp members 15 10 to receive the lower ends of the backs of the music-sheets, so that the whole of the lower edges of the sheets of music will engage the shelf 13 and rest thereon.

Extending centrally from the lower surface of the shelf 13 is a stud 34, having a longitudinal groove or channel 35, and with its outer end threaded, as shown. Superimposed upon this stud 34: are a plurality of shallow cylindrical casings closed at one end and open at the other end and each provided with a cleft in its rim, as shown in Fig. 3. The casings are rotatively mounted upon the stud by means of central apertures in their closed ends and will be arranged with the closed end of each casing next to the open end of the adj aeent casing, as shown. Extending from each casing is an arm terminating in a leafengaging clip, as shown. As many of the easings and their arms may be employed as desired; but for the purpose of illustration three of each are shown, the casings being denoted by the characters 36, 37, and 3S and their respective arms by the characters 39 a0 41, as shown. A closing cap-plate 4:2 will be employed over the outermost casing and held in place by a clamp-nut l3 upon the threaded end of the stud. By this simple means the casings are all held rotatively in position. Each of the casings will be provided with a cleft in its rim, preferably next to its extending arm, one of which is indicated at 44 in Fig.

The arms 39 40 n are of increasing lengths, the uppermost arm being the longest and provided, respectively, with spring-clips 45 46 47, adapted for connection with the sheets of music. By thus arranging the arms of graduated lengths the clips can be arranged partially underlapping to enable the leaves to lie in closer relations both when opened and closed and also to render the clips more accessible to the performer.

Within each of the casings 36 37 38 a coiled spring 54 is disposed with one end in the channel 35 and the other in the cleft 44 in the casing. The springs thus exert their force to throw the arms and their clips from left to right in the direction in which it is desired to turn the leaves.

Each of the arms 39 a0 41 is provided with a depending lip or lug, (denoted, respectively, at 48, 49, and 50,) and at the right side of the shelf 13 are spring-catches 51 52 53 in the paths of the lips and with which they are gle bracket or head 57 and will each have its own independent spring, so that it may be independently actuated. By this simple arrangement it will be obvious that any piece of music cohtaining three or more leaves may be set by its back edge between the clampjaws 15 1G and the sheets to be turned connected, respectively, to the clips 45, 4G, and 4L7 and then turned over until the lips on the arms engage the catches. Then a mere touch by the performer upon the keys on the catches will release the arms consecutively and permit the springs in the casings to throw the arms over, carrying the music-sheet with it, thus turning the sheet. The movement necessary to operate the releasing-keys will not be sufficient to interfere with the playing, and will not, therefore, be noticeable to the listeners or otherwise interfere with the performance. \Vhen employed to turn the leaves in music-books, the action and mode of operation is the same except that the clamp member 15 16 will not be required, the covers of the book being held by the clips 31 32 upon the bars 29 30, as before stated.

The whole structure is very simple, easily.

applied, and may be employed in any locality where music is to be supported and turned during the performance.

Having thus described the invention, what I claim is A music-leaf turner comprising a supporting-frame, a plate connected to said frame and having the stationary jaw member of a leaf-clamp extending therefrom, the movable jaw member of the clamping means movr bly connected to said stationary jaw member, springs disposed to maintain said movable jaw member in yieldable position, said plate having an elongated aperture enlarged at one end and with a lateral extension at the other end, a stud extending from the music-rack and having an enlarged head corresponding to the enlarged end of said aperture, and a hook movably connected to said plate and engaging said stud beneath its head to lock it into the lateral extension in said aperture, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
