MUSIC-LEAF TURNER.

SPECIFICATION fcrming part of Letters Patent No. 676,737, dated June 18, 1901.

Application filed March 8, 1901. Serial No. 50,288. (No model.)

To all whom it may concern:

Be it known that I, FRANK SEDGWIOK DUELL, of Abington, in the county of Plymouth and State of Massachusetts, have invented'certainnew and useful Improvements in Music-Leaf Turners, of which the following is a specification.

This invention relates to music-leaf turners; and it consists in certain novel features of construction and arrangement, which I shall now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a front elevation of my improved device in position on a piano. Fig. 2 represents a front elevation of the device, showing the parts in a certain position. Fig. 3 represents a similar view showing the parts in another position. Fig. 4: represents a detail front elevation of the hinges at the inner ends of the arms. Fig. 5 represents a horizontal section showing the levers for operating the trip-rods. Fig. 6 represents a side elevation of said levers. Fig. '7 represents a section showing the upper ends-of the rods. Fig. 8 represents a detail perspective view of one of the leaf-engaging clips. Fig. 9 represents a detail view showing a modification.

The same reference characters indicate the same parts in all of the figures.

Referring to the drawings, 1 represents a back or support, which maybe the back-board of the music-rack on a piano or other instrument or may be a member separate from the instrument, and 2 2 represent two arms hinged to swing horizontally. and provided with clips 3 3, here shown as two in number on each arm, saidclips being adapted to fasten to the sheets or leaves of the musical composition along the upper, edges of said leaves. In the drawings two arms 2 are shown, as this number will suffice to turn the leaves of ordinary sheet-music, but a greater or less number may be provided if desired. Each of the clips 3 ismountedupon a 'U- shaped wire frame 4., whose ends 5 5 are coiled around the arms 2, which latter are preferably cylindrical in form and maybe made of wire of the desired stiffness. The frames 4:

are adapted to rotate about the arms 2 and may also be adjusted longitudinally of said in such a direction as to tend to throw the arms 2 2 over from right to left.

At 9 9 on the right of the support 1 are mounted two substantially vertical trip-rods, whose upper portions are slidingly mounted in a guide member 10, while their lower ends are engaged with the inner ends of two sub stantially horizontal finger-levers 11 11, pivoted at 12 near the lower edge of the support 1. .These levers have heads or keys 12 12 at their outer ends, adapted to receive the pressure of the performers finger. The trip-rods 9 9 are provided with hooked upper ends 13 13, adapted to take over the arms 2 2 near the outer ends of the latter, and the lower ends of the trip-rods are provided with weights 14: 14, which normally depress the trip-rods into engaging position. The arms 2 2 are of sufficient flexibility so that when brought over to a right-handward position, as shown in Fig. 2, they maybe slightly bent down and inserted underneath the hooks l3 13 on the trip rods, .which hooks are turned forward, as shown in Fig. 7, and when thus engaged with trip-rods the arms 2 2 will be held against the tension of their springs 8 in the described right-handward position. When it is desired to release one of the arms 2, the corresponding lever 11 is struck somewhat sharply to depress its outer end and elevate the corresponding trip-rod 9, so as to release the said arm 2 and permit it to swing over to a lefthandward position, as shown in Fig. 3, and

thus turn the music-sheet 15, to which it is sethe corresponding levers so as to turn the music-leavesin succession. Each of the arms 2 is provided at its outer end with a buffer 16, having a soft facing 17, of felt or other suitable material, adapted to strike against the base 1 and arrest the left-handward movement of the arms 2 with as little noise as possible and without injury to any of the parts. In Fig. 9 the buffers are'represented in the form of soft-rubber balls 18 18, aftixed to the arms 2. I I

Owing to the fact that each of the arms 2 is horizontal and straight, the clips may he slid along thereon to accommodate sheets of varying sizes, and since each horizontal arm is controlled by its individual vertical triprod, which in turn has its own finger-leverfor actuating it, there can be no possibility of releasing more than one of the arms 2, provided only one lever 11 is actuated. Since the leversll' engage the lower ends of the vertical'rods, said levers will actuate the rods with certainty to the full extent necessary to release the swinging arms, and since each arm 2 carries itsown buffer 16 the buffers cannot get out of place even if the rods should become somewhat bent.

I claim- 1. In amusic-leaf turner, asupport or back, a plurality of straight horizontal arms'hinged to the. upper part thereof and each having one or more leaf-engaging clips, springs normally throwing said arms in a left-handward direction, a "ertically-moving trip-rod for each arm extending from the. lower to the upper part of said back and at its upper end adapted to hold said arm in a right-handward position and means engaging the lower end of each of said rods to elevate the same and release an arm.

2. In amusic-leaf t,urner, a support or back, a plurality of straight horizontal arms hinged to the upper part thereof and'each having one or more leaf-engaging clips, springs norrod, and pivoted finger-levers engaging the lower ends of said rods and adapted to be in- Y dependently actuated to,elevate the rods to release the arms.

3. In a music-leaf turner, a support or back, a plurality of straight horizontal arms hinged to the (upper part thereof and each having one or more leaf-engaging clips, springs nor mally throwing said arms in a left-handward direction, a vertically-moving trip-rod for each arm extending from the lower to the up per part of said back and having a hooked upper end adapted to engage an arm and hold it in a right-handward position, and means engaging the lower end of each of said rods to elevate the same to release the arms.

4. In a music-leaf turner, asupport or back, a plurality of straight horizontal arms hinged to the upper part thereof and each having a plurality of leaf-engaging devices'mounted on it, each of said devices comprisinga U- shaped clip-suspending frame composed of wire having its ends coiled around thearm and a clip mounted to swing on said frame, 1

springs normally throwing said arms in a lefthaud'ward direction, a vertically-moving triprod for each arm extending from the lower to the upper part of said back and at its upper end adapted to hold said arm in a right-handward position and means engaging the lower end of each of said rods to elevate the same and release an arm.

In testimony whereof I have attixed my signature in presence of two witnesses.
