MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 356,983, dated February 1, 1887.

Application filed September 22,1886. Serial No. 214,273. (No model.)

To all whom itmay concern: Be it'known that l, PATRICK LYNETT OAR- DEN, of Dixon, Solano county, State of California, have invented an Improvementin Music-Leaf Turners; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the class of musicturners; and myinvention consists in the novel arrangement and construction of the leaf-holding arms, the operatingkey, the power-transmitting mechanism between the key and the leaf-holding arms, by which they are successively actuated, the adjustable frame for attaching the device to the rack of the piano and for holding music of various length,and various details, all of which I shall hereinafter fully describe.

The object of. my invention is to provide a simple and effective music-leaf turner adapted to be readily attached to the rack of any piano and to be easily operated.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a perspective view showing the application of my music-leaf turner to the rack of a piano. Fig. 2 is a perspective view showing the details of the power-transmitting mechanism.

Ais the piano, having the ordinary rack, a.

B is a standard, the lower portion. of which is provided with a foot, I), which rests upon the base of the rack a. Fitted to the face of the standard is a sliding bar, D, which by its movement adapts the length of the standard to any length of music. This bar may be fitted to the standard in any suitable manner, though I have here shown a set-screw, 0?, projecting within a slot, (1, made in the standard. By adjusting this set-screw the sliding bar may be fixed in the position to which it is adjusted. v

The face of the bar D is grooved, as shown at (1 for the reception of the back of the music or musicbook, and on each side of the groove are arranged spring clasps d, for cl an1p .ing the back of said music or book.

To the top of the sliding bar D is hinged, at c, the arm 0, which passes down behind the manner. The hinging of the bar and the arm together provides for the ready application of the device to-any rack. Hinged at e to the top of the arm 0 is the box or casing E, the angle of which is regulated by means of the set-screw e, passing through a short bracket, 6 on the base of the box and bearing against the arm 0. Within this box is mounted the shaft F, upon which is secured the gearwheel H.

I is a key let through the base of the rack a, its outer end projecting within convenient reach of the player. It is suitably pivoted or fulcrumed, and has loosely connected with its rear end the rod Jr This rod extends upwardly,and has pivoted to its upper end within the box a rackbar, L, which is held forward to its engagement with the gear-wheel H by means of a spring, Z. A spring, j, around the rod J throws it back again when the key is relieved. that the rack-bar L must be thrown from its engagement with the gear H, so as not to reverse it. the box an inclined plane or cam, M. Secured to the back of the box is a strip, N, having made in it a T-shaped groove, n. On the back of the rack-bar L is a stud, Z, with a head. Now, when the rack bar has been moved to the upper limit of its stroke, its upper end coming in contact with the inclined plane or cam M, it is forced back on its pivotal center until the head of its stud Z enters the open top of the groove a. The rack-bar is thus held away from the gear, and may move down with the rod J under the influence of the spring j. I

Pivoted in the top of the box are spindles O, the lower ends of which are provided with pinions 0. With these engage segmental gears f, mounted on the shaft F in different positions, so that their action may be successive. Connected with the spindles O in any suitable manner, as by simply fittingin sockets therein, are the arms 1?, the ends of which are provided with the leaf-clamps Q. Thesemay be of any suitablecharacter adapted to clasp the music-leaves. There may be any desirable number of said arms.

In thus returning, it is obvious To effect this I have at the top of I The operation of my music-leaf turner-is as 100 50 rack, and is secured thereto in any suitable follows: As I have heretofore mentioned, the standard 13, with its sliding bar D and hinged arm 0, maybe adjusted readily to the rack, as shown in Fig. 1, and the boX E may be then adjusted to the proper angle by means of the set-screw e. The sheet-music or the book is then fitted to-the grooved face of the adjustable bar D, and is secured by the springclamps d. It is then opened out, and one of the clamps Q is secured to each leaf. Then the time comes for turning the first leaf, the key I is dcpressed,whereby the rod J is forced up, thereby, through the rack-bar L on its top, effecting the partial rotation of the gear H and the shaft F. The first of the'segmental gears f is thus caused to engage the pinion 0 of the spindle O, carrying the first arm I, and to partially rotate said s indle,whereby it throws said arm over to the other side, thus turning the leaf. The movement of the rack-bar L is great enough to carry its upper end against the cam DLwhereby it is thrown back and held by the engagement of its stud Z with the grooved strip N, and being thus free from the gear-wheel II, it moves down to its initial position under the influence of the springj, leaving the gear in the position to which it had been turned, so that at the next operation of the key the second segmental gear is ready for its engagement. As each leaf has to be turned the keyis operated as described, and at each operation the engagement of the rack-bar with the gear is broken, so as to leave the shaft ready for a continuance of the operation.

The whole device can be made in such small compass as not be in the way in any manner. The position of the operating-key, right in front of the operator, renders its use very convenient, as the motion needed to reach it and the power to operate it are scarcely greater than in operating the ordinary keys of the piano. If, however, it be found desirable, the rod J, instead of terminating at the base of the rack and being operated by a key at that point, may pass on down to a suitable treadle below, whereby the turner may be operated by the foot.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
