MUSIC-LEAFYTU RN ER.,

SPECIFICATION forming part of Letters Patent No. 565,308, dated August 4, 1896.

Application filed July 9, 1895. Serial No. 555,422. (No model To all whom t may concern,.- Y

Be it known that I, JOHN J. VALSH, of Yonkers, in the county of Vestchester and State of New York, have invented anew and Improved Music-Leaf Turner, of which the following is a full, clear,and exact description. My invention has for its object to provide a music-leaf turner capable of being att-ached to a piano, organ, or to a music-stand of any description without screwing or otherwise fastening the device to the support provided for it, thereby preventing the marring of the casing of the instrument or chaflng a stand.

Another object of the invention is to construct a musicdeaf turner in an exceedingly simple and durable manner, and to provide devices for attaching leaves of music to the several arms of the machine in a manner which will not act detrimentally to the sheets.

Another object of the invention is to provide for a quick releasing of the arms when' a sheet of music is required to be turned, and furthermore. providing a construction whereby all of the music-carrying arms of the machine may be simultaneously carried over to a position to receive the leaves, and locked in such position.

The invention consists in the novel construction and combination of theV several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a piano having the leaf-turner applied thereto. Fig. 2 is a vertical section through the leaf-turner, taken at a point near the center. Fig. 3 is a partial rear View of the leaf-turner, parts being broken away; and Fig. 4 is a detail perspective view of the leaf-receiving end of one of the leaf-carrying arms.

In carrying out the invention a casing A is provided as the body of the machine, and this casing is of box-like construction and need notnecessarilybevery large. The casing is preferably open at the vback in the interest of lightness, and at the Aupper back portion of the body or casing of the machine at each side a rearwardly-extending bracket 10 is formed, and these brackets are adapted to fit upon the ledge of the ordinary music rack of a piano or organ or rest upon the leaf -supporting edge of the music stand. hen the machine is applied to a piano, as shown in Fig. 1, the body or casing will extend down from the usual rack to a point near the keyboard.

The body or casing has a ledge 11 secured upon its upper front edge, upon which the music is to rest, and this ledge extends any desired distance beyond each side of the casing. A music-rest 12 of any desired description` and corresponding to the music-rack of the instrument is hinged upon the back portion of the bod y andis supported, preferably, in a rearwardly-inclined position by means of arms 13, pivoted to the rear extensions of the casing and bearing against a batten formed upon the rear of the said rest. These supporting-arms 13 may be independent of each other or they may be connected at the top.

The book or cover for the music is held in engagement with the front of the rest-board of the machine and the said rest-board pressed against the arms 13 through the medium of clamping-arms 14 of spring character, which emanate, preferably, from the forward edge of the ledge 11 and have bearing at their upper ends against the front face of the said restboard, one near each side, as shown in Fig. 1, while a center pin or bar 15 is secured to the ledge 11 at its lower end and projects upwardly toward the upper edge of the restboard 12. This pin or bar 15` serves to hold the sheets of music in place. This pin 15 is adapted to be placed vertically along the central portion of Sheetmusic or abook of music, being between the leaves at opposite sides, `and if in practice it is found desirable this pin may be of spring material and rigidly secured to the ledge 11 at its lower end, being free at its upper end.

Brackets 16 and 17 are formed upon the front of the casing, preferably at or near the center, and in these brackets the ends of a shaft 18 are firmly fastened. This shaft is adapted as bearings for music-carrying arms C. Any desired number of these arms may be employed, and the arms are arranged one below the other and are graduated in length, the lower one being the longest and the upper IOO one the shortest. The arms comprise practically a substantially horizontal member c and a vertical member c', the vertical members of all of the arms being parallel, as is shown in Fig. 3.

Each music-carrying arm at the inner end of its horizontal member c is provided with a sleeve 19, through which the shaft 1S is passed, and springs 2O are coiled around the shaft between the arms and the arms of the brackets in which the shaft is secured, the springs being secured at one end to the shaft and attached at their opposite ends to the horizontal members of the arms. ency of these springs is to carry the arms over to the left-hand side of the machine, but the arms should be placed at the right-hand sideof the machine when the sheets of music are attached to them and before the machine is operated.

The vertical member c of each music-carrying arm C is provided with a device for securing the sheet or leaf music to the arm, and this device preferably consists of a wire which is bent or coiled upon itself, as shown at 2]. in Fig. 4, the sheet or leaf to be attached to the arm being passed between adjacent members of the coil, and if in practice it is found desirable the music-carrying arms may be made of stout wire and the coil or music-receiving device 21 be formed of the same material.

Each musicu'ecciving device or coil is provided, preferably, with a disk 22 upon its front face, adapted to have a number produced thereon, and the numbers on the various arms read from the innermost or shorter arm outward, as, for example, 1, 2, and 3, the numbers being intended to indicate the leaves that have been turned, as, for example, when two of the arms have been shifted over the ligure 3, appearing on the third arm still in position, will indicate that two leaves have been turned.

The music-carrying arms are held at the right-hand side of the machine by means of latches 23, which are made to extend through an opening 24 in the front of the casing, and are pivoted at their rear ends on a rib 25,10- cated at the rear of the casing and held by a cross-bar, as shown bcst in Fig. 2, and each latch terminates at its free end in a head adapted to receive and hold the musie-carrying arms, the number of latches corresponding to the number of arms. Each latch has a link 27 attached thereto, and these links are carried downward to the bottom portion of the casing, where each link is pivotally attached to a key-lever 28, fulcrumed in the lower portion of the casing and extending out through the front board, slots 30 being provided for the purpose, and each key-lcver at its outer end 'is provided with a disk 2f), or

The tendthe equivalent thereof, to be struck by the finger when the sheet of music is to be turned. These disks bear numbers corresponding to the numbers on the music-carrying arms that thc latches they are connected with control, so that when the first leaf is to be turned the key marked l is pressed. If the third leaf is to be turned, the key marked 3 will be pressed and the third arm will swing, carrying with it the appropriate leaf. lVhen a key-lever is pressed, the latch 23 with which it is connected is raised and the arm that it engaged will be released, and the spring conf trolling that arm will carry7 it over to the lefthand side of the machine.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l.. In a music-leaf turner, the combination with a casing provided with a bracket proj eeting from its rear face for supportin git, and leaf-carrying arms carried by the casing, of a music-rest hinged to the casing, and arms secured to the bracket of the casing and engaging the rest to support it in an inclined posi tion, substantially as described.

2. In a musicleaf turner, the combination with a casing provided with a ledge on its upper front face and with a bracket projecting from its rear face for supporting it, and leaf-carrying arms carried by the casing, of a music-rest hinged to the casing, and arms pivoted to the bracket of the casing and engaging the rest tohold it in an inclined position, substantially as described.

In a music-leaf turner, the combination with a casing having an open rear portion and having its side walls extended rearwardly to form brackets capable of supporting the casing, of a cross-bar extended across the open rear portion of the casing and having a rib thereon, a series of catches pivotally mounted on the rib and projected forwardly through an opening in the front of the casin g, a series of leaf-turning arms pivoted on the casing and respectively engaged by the catches, means for swinging the leaf-turning arms, a link lpivotally connected to each catch, and keys mounted in the casing and respectively pivoted to the links, substantially as described.

4. In a music-leaf turner, the combination with a casing, of operated leaf-turning arms, a musicrest hinged on the casing, an arm rising from the casing and supporting the music-rest, and a spring engaging the n1 usicrest and pressing the same against the arm, substantially as described.
