MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 439,759, dated November 4, 1890.

Application filed June 8, 1889. Renewed August 26,1890. Serial No, 363,113. [No model.)

T0 at whom it may concern.-

Be itknown that. 1, SOLOMON LEivY, a citi- Zen of the United States, residing at Harrisonville, in the county of Cass and State of Missouri, have invented a new and useful Music-Leaf Turner, of which the following is a specification.

This invention has relation to music-sheet turners adapted for use in connection with any instrumentsuch as a piano, organ,&c.; and among the objects in view are to provide a device of the above description, the mechanism of which is designed to be operated by foot and to turn the sheets successively from right to left, and to provide a reversing mechanism whereby the music may be reversed when a repetition thereof is de sired.

The invention consists in certain features of construction hereinafter specified, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of a piano provided with an attachment constructed in accordance with my invention. Fig. 2 is an enlarged perspective of the attachment detached. Fig. 3 is a side elevation; Fig. 4, a central vertical section; Fig. 5, a detail in perspective of the tripping mechanism; Figs. 6 and '7, details of arrangement of minor parts located at the upper ends of the bracket or stand; Fig. 8, a perspective in detail of a substitute music-book support; Fig. 9, a similar view of the operating-pedal; Fig. 10, details of the bell-crank connections.

Like letters and numerals of reference indicate like parts in all the figures of the drawings.

I have herein illustrated my invention as applied to a grand square piano, and have provided the necessary adjuncts for operating the mechanism as applied; but as 1 do not limit the application of my invention to pianos of any style, or, in fact, to any instrument or stand, the adjuncts herein described are subject to variance not considered necessary to be herein shown or specifically de scribed, but which may suggest themselves to persons skilled in mechanics and which will be considered wholly within the scope of my invention.

A represents a grand square piano; B, the side wall of the casing; C, the front wall, or

that arranged in rear of the key-board, and D the usual pedal-support. 4

1 represents a clamping-plate designed to embrace the upper and lowersurface and rear edge of the front wall O, the same being bound in position in this instance by ordinary setnuts 2. Intermediate the set-nuts is formed upon the upper surface of the clamp 1 athreaded or other formed socket 3, in which is fitted a vertically-disposed shaft 4, braced by diagonal braces 5, extending from a point slightly above the socket to the clamp. At each side of the socket 3 there rises from the clamp 1 a bracket-arm 6, the two arms being opposite each other and connected by tie-sleeve 7 near their upper ends, through which sleeve passes a bolt 8, and in the sleeve terminates and is secured the upper end of the shaft "zir- The opposite bracket-arms 6 and the shaft 4 are slightly inclined to the rear, as shown, and the said bracketarms are preferably braced near their lower ends by a transverse tie-bar 9, carrying at its outer end a bearing 10.

Mounted upon the shafte immediately below the sleeve 7 is a sleeve 11,from which depends the leaf-shaft 12 of the device, the same being connected to the sleeve 11 in this instance by a screw 13. At one side of the sleeve 11 is mounteda rock-arm 1e,from the rear end of which there depends a pivotallyconnected rod 15, the lower end of which is loosely connected with a bell-crank lever 16, pivotally connected with a bearing 17, made adjustable and mounted upon the shaft 4:. A bail or brace 18 extends from the opposite arms 6, and is pivoted thereto by means of a bolt 19, provided with nuts, and takesunder the leaf-shaft 12, whereby the same may be by the raising and lowering of the bail set at different inclinations with reference to the shaft 4: and arms 6, which shaft and arms constitute the bracket or standard of the device. Upon the leaf-shaft 12 near its upper end is mounted a pulley 20, which has a sleeve depending therefrom upon the shaft- 12 and terminates in a boss 21, having a set-screw 22, and provided with a laterally-extending rockarm 23, moving in unison with the pulley.

Mounted upon the sleeve portion 24 of the pulley and moving independent thereof is a collar 25, from which projects at the side agreeing with the rock-arm 23, a lug 26, which abuts against a keeper 27 extending from a fixed collar mounted oppositely near the upper end of the shaft 4. From the opposite side of the collar 25 there projects a rock-arm 28, near the outer end of which is pivoted a pawl 29, normally pressed by a spring 30, so as to throw the same inwardly or toward its collar. The fixed collar 31,from which the keeper 27 projects and which is mounted upon the shaft 4, is provided at that end opposite the keeper with a pulley 32. Above this collar just described is mounted a collar 33, fast to the shaft 4, and from both sides there pro-- jects a pulley 34.

'When it is desirable to use the music bound in book form, I provide an ordinary wire rack 36, at the upper end of which I form an eye 37 and to the lower end an eye 38, having at either side right-angle projections 39, serving as a support for the book. A small collar 40, having a set-screw, is'inserted upon the shaft 12 directly under the Wire frame 36 and serves to support the same upon said shaft.

My invention, however, is designed more particularly for use in sheet-music, wherein is meant the employment of several independent disconnected sheets, and for this reason 1 provide upon the shaft 12 a series of two or more sheet-leaves 41. These sheet-leaves consist of a longitudinal strap of like metal provided at its upper and lower ends with eyes 42 and having at its free edge a series of laterally-disposed straps or fingers 43. At the upper edge or end of the strap 44 of each leaf is provided a laterally-projecting trip 45, extending to the right and adapted for engagement with the inwardly-pressed feed-pawl 29. In order that the leaves may be turned by said pawl in succession,I provide that leaf at the left of the series with a longer trip 45 than I do the next succeeding leaf, and so on throughout the series. These trips are also arranged so that the longer trip is upon the outside of the series when the straps or leaves are nested and. before the music is openedthat is to say, when said trips are together they form a circle eccentric with the shaft 4. If desired, I may provide the leaves of musicbooks with trips, as 45, and arrange the same in the same manner as I do upon the leaves herein described.

Secured to the upper of the series of pulleys herein designated as 20 is a cord 46, which, after passing partially around the pulley at its left side, is passed over the small pulley 34 upon the sleeve 33 and at the left of said sleeve, and is connected with a coiled spring 47, the lower end of said spring being connected with the transverse bar 9. Asec- 0nd cord 48 extends from the said point upon said pulley around the right-hand side thereof and over the opposite pulley 34 upon the sleeve 33, and is connected by a wire or other connection 49 to the upper end of a bellcranklever 50, pivoted in the bearing 10 at the outer end .of the bar 9. A cord 51 is rigidly connected with the sleeve 25 and passes to the left of the sleeve around the same, and is connected with the freeend of the rockarm 14, the opposite end of the cord passing around the right of the pulley and over the pulley 32 upon the sleeve 31 and from thence downwardly, and is connected with a spring 52, the lower end of which is connected with a peg 53, extending from the fixed collar 17, in which is located the bearing for the bellcrank lever 16.

Referring more particularly to Figs. 1, 10, and 11, 54 represents a clamp having a setscrew 55, adapted to secure the clamp upon the upper edge of the Wall E of a piano-casing, and at the outer end of said clamp there is pivoted a bell-crank lever 56, this clamp being arranged at the right of the device. 57 represents a clamp-arm projecting from the under side and secured to the piano-casing, which clamp-arm is preferably connected and braced to the clamp 54 by means of a tie-rod 58. A bell-crank lever 59 is mounted at the outer end of the clamp 57. From the lower end or angle of the bell-crank lever 50 there extends a wire 60, which connects with the upper end of the bell-crank lever 56, and from the lower end of the said bell-crank lever 56 there extends a wire 60,which connects with the upper angle or end of the bell-crank lever 59 and extends from the lower end of the same to the lower end of a bell-crank lever 61, pivoted in a bearing-plate 62, located at one side of the pedal-stand D. From the upper arm of the lever 62 there depends a continuation of the wire 60, which connects by means of a swiveled socket 63 with a pedal 64, pivotally connected to a clamp 65, bound by nuts 66 to the side or edge of the support 13. A duplicate pedal 67 is pivotally connected to a plate 68,- which plate is secured by a set-screw 69 to the opposite edge of the pedal-support D, and connected with the swiveled socket 69 of the pedal is a wire 70, which is connected at its upper end to a bellcrank lever 71, pivoted in a plate 72, secured to the under surface of the piano casing. From the lower arm of the bell-crank 71 there extends a wire which is carried around the end of a piano, preferably by bell-crank 1e vers, as 59 and 56, which may be mounted at the opposite sides of the clamps 54 and 57,

said wire being connected with the lower end of the bell-crank lever 16 by means of, in

this instance, a swivel-socket 72.

The operation of my invention may be' and through the medium of the wire 70 and the various bell-crank mechanisms 71, 59, and 56 motion will be imparted to the bell-crank 16, the upper end of the same being drawn downwardly, and by reason of the consequent downward motion given the rod 15 the rear IIO end of the rock-arm 14 will be drawn downwardly and its opposite end raised, and through the medium of the cord 51, which connects the free end of the rock-arm with the sleeve 25, said sleeve and the rock-arm 28 will be rotated from right to left and carry therewith the pawl 2 which is in engagement with the upper of the series of trips 45. It will thus be seen that the first sheet is turned and the operation of the turning of each succeeding sheet is but a repetition of that just described. It will also be observed that the rock-arm 28 is operated against the tension of the coiled spring 52, as the cord 18 connects the same with the pulley.

I have now described the means for turning the several sheets in succession in the act of reading the music, and I will now proceed to describe a means whereby the music may be reversed for repetition. To reverse the music, pressure is applied to the righthand pedal, or that designated 64., and through the wireconnection and the bell-cranks 61, 59, and 56 the bell-crank motion is imparted to the bell-crank 50 and from thence to the cord 48, and the pulley 2O willbe rotated from left to right against the tension of the spring 47, which is connected to the opposite side of the pulley by the cord at As the pulley is rotated from left to right its sleeve and the rock-arm 26 are thrown from left to right and strike against the series of trips, or, it may be, one trip, in accordance with the number of leaves previously turned, and reverse the said leaves to their original position, said rockarm being returned to its normal position by means of the coiled spring 47.
