THOMAS A. FARRELL, OF CHICAGO, ILLINOIS.

MUSlC-LEAF TURNER.

SPECIFICATION forming part of Letters IPatent No. 574,244, dated December 29, 1896.

Application filed February 26, 1896. Serial No. 580,768. (No model.)

To all whom it may concern:

Be it known that I, THOMAS A. FARRELL, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Music-Leaf Turner, of which the following is a full, clear, and exact description.

The object of the invention is to provide a music-leaf turner simple and economic and so constructed that the leaves may be expeditiously and conveniently turned whether the music be printed in book or in sheet form; and another object of the invention is to provide means for holding the leaves or sheets of music firmly upon the rack during the period when such sheets are at rest.

Another object of the invention is to construct the music-turner in such manner that the leaves may be turned with but little exertion on the part of the operator and in such manner that the sheets will not be torn during the operation of turning them.

The invention consists in the novel con struction and combination of the 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 front elevation of the improved music-leaf turner, illustrating a book in position thereon; Fig. 2 is a plan View of the music-leaf turner, illustrating the turning-arm and parts connected therewith in their normal position in positive lines and in dotted lines in position to effect the turning of a leaf; and Fig. 3 is a detail view of the rear side of a guide-plate and the device carried thereby for operating a plunger forming a portion of the machine.

In carrying out the invention a rack A is provided as the body of the music-leaf turner, the said rack being adapted to rest upon a music-stand, or the rack ordinarily used upon pianos and like instruments to support the music. The rack A has a base-bar B adj ustably attached to its forward face, the rack having vertical slots 10 made in its end portions to receive set-screws 11, carried by the basebar. A shaft 12 is vertically located at or near the central portion of the rack, and the said rack extends beyond the top and the bottom, being loosely mounted in the rack, or in such manner that the shaft may have limited end movement as well as a rotary movement. In the upper rear portion of the shaft 12 a recess 13 is made, the upper and lower walls whereof are given a diagonal disposition, as shown in dotted lines in Fig. 1. These Walls are also approximately parallel with each other. In this recessed portion of the shaft a horizontal member of a leaf-turning arm 14 is pivoted, the said arm comprising a vertical and a horizontal member. The vertical member extends downward in front of the rack. At the lower end of the said shaft a crank 13, or a handle of any other description, is secured, extending sufficiently out beyond the front of the rack to be readily manipulated by the hand of the player. The shaft 12 is limited in its downward movement by a pin 15, passed through it and engaging with the top of the rack, and the handle 13 limits the upward movement of. the shaft, while its rotary movement is limited by reason of the horizontal stop-pin 15 at the top of the shaft engaging with the vertical stop-pin 16 secured upon the rack. The purpose of allowing the shaft 12 endwise movement will hereinafter appear.

Im mediately to the rear of the upper end of the shaft 12 a casing 17 is secured to the back of the rack, the casing extending a predetermined distance above its upper edge, and the central portion of this casing, or that immediately opposite the shaft 12, is concaved uponits front face. The concaved surface of the casing has a plate 18 secured thereto,

which plate is placed diagonallyof the casing and conforms to the curvature of the casing and has an inclination downward from its right-hand end in direction of its left-hand end, the lower end of the plate being brought quite close to the top of the rack. The shape of the inclined plate 1.8 is shown best in Fig. 2, from which figure, and likewise from Fig. 1, it will be observed that a space intervenes the ends of the plate 18 and the vertical side portions of the curved sides ofthe casing. The short arm of the rod lat is adapted to engage the plate 18 as the shaft 12 turns in its bearings. As the shaft moves to throw the short arm rightward in Fig. 1 such arm will slide along the under face of the plate and the long arm of the rod will be raised, and as the shaft recovers its normal position, that is, moves to the left, the short arm will ride along the upper face of the plate 18, and in so doing the arm It just forward of its pivot will engage the upper end of the lower wall of the recess 13, so that the shaft 12 will be lifted in its bearings. \Vhen the short arm of the rod 1% passes the right-lnind extremity of the plate 18, the shaft 12 and its attached parts will gravitate to the position shown in Fig. 11 and the said parts will he ready to repeal: the operation.

A shaft 19 is journaled in bearings 20, located at the upper right-hand portion of the rack, and the said shaft has a crank-arm 21 attached to it, the vertical member whereof extends downward a predetermined distance in front of the rack. ed to hold the right-hand leaves of the book or sheet of music in position on the rack, and is normally maintained in such relation by means of a spring 22, and the said spring is ordinarily coiled around the shaft, one end being secured to the shaft and the other end having bearing against the rear face of the rack. The arm 21 also serves to prevent a plunger, to be hereinafter described, from bowing or placing more than one sheet in position to receive the turning-arm.

The shaft 1.) has a second crank-arm 23 secured to it. This crank-arm extends rearwardly, or beyond the rear face of the rack, and one end of a chain 21L is secured to the rear crank-arm 223, the said chain being passed over the guidenilley 25, located atthe rear of the rack, the opposite end of the said chain having an attachment to an arm 26,11orizontally projected from the shaft 12, preferably between its center and upper end. A second horizontal arm 27 is projected from the central portion of the shaft 12, and these two arms 26 and 27 extend in direction of the right-hand end of the rack when the music-turning arm 1% is in its normal position, engaging with the the rack, as shown in. Fig. 1 and in positive lines in Fig.

A plate 28 is secured to the right-hand end of the rack A, being preferahlyfiush with the front face of the said rack, and the plate extends apredetermined distance outward from the rack in a horizontal direction. This plate 28 has a longitudinal slot 2!) made therein, extending nearly its entire length, and main slide or guide ways 30 are formed upon the front face of the plate at each of its sides to receive a slide 31, having movement over the slotted surface of the plate.

A bracket 32 is secured to the inner end of the slide and extends forwardly therefrom in a horizontal direction, and upon the outer end of this bracket an arm 33) is fulcrumed between its outer end and its center. A loop or strap is formed at the inner end of the arm 01' other form of socket may be provided, to receive a block 35, made of a yieldlhis crank-arm is adapting material-as, for example, ruhber-the said rubber being brought in contact with the vertical edges of the right-hand leaves to bulge the said leaves at the central portions of the pages, as shown .in dotted lines in Fig. 2, in order that a space maybe made between the uppermost right-hanifl leaf and the next leaf especially for the reception of theniusieturning arm, and this block, which may be termed a follower, must release the right hand leaves just before the turning-arm acts to throw a leaf over from right to left. This release is preferably accomplished as shown in Figs. 2 and 23, in which it will be observed that a link ill) is pivoted to the outer end of the follower-arm 3 3 and passed through an opening 36 in the slide ill and through the slot 25) in the body-plate for the slide.

A foot 137 is pivoted upon the rear end of the link 36, and the ends of this foot are bevcled in opposite directions, and when the follower is in its normal position, and before it is carried forward to form a space between the leaves, the foot will incline in direction of the back of the base-plate 28, being held in that position by a spring 37. (Best shown in Fig. 23.) This spring is coiled around the pintle of the foot and oetalpies an (awning formed in the foot.

On the forward movement of the follower the foot 37 will move between auxiliarw slidewavs 38, secured on the back of the base-phtte of the slide ill, and hold the follower against the leaves while the said follower is being carried inward over the rack; but when the foot is passed out at the rear of the slideways as the feet will assume the inclined position which it had before entering its slideways, as shown in dotted lines in lrig. .Land when the follower is carried backward the foot will ride upward upon the slideways 3S, drawing rearward the free end of the follower-arm and, carrying the follower forwardly out of engagement with the leaves, the follower dropping i to an engagementwith the right-hand leaves left-hand sheet to hold the said sheet close to again the moment that the foot has passed over the outer end of the slideways 3 and assumed its normal position.

A guide-ln'acket 39 is attached to the back of the plate 28, extending hin'izontally below and rearward of the guideways 38. The said bracket is provided with an upwardly-ex tending flange at its rear side, and the said rear side of the bracket is inclined, its inner end being higher than its outer end, and the said flange of the bracket forms a guide for the 5 foot 37 in its passage over the slideways. Motion is given to the slide I31 through the medium of a rod ill), attached to the slide and pivotally connected. to the lower arm 27 on the shaft 12.

In the operation of the n1usie-leaf turner the arm 21 will normally hold the righi-lnuid sheets in position on the rack, while the turning-arm ll will perform the same function for the left -hand sheets. \Vhen a sheet of music is to be turned, the crank or handle llO '13 is moved toward the right-hand side of the rack, whereupon the plunger 35 is moved forward in the manner described to form a space between the outward right-hand sheet and the next sheet thereto. Simultaneously the connection between the main shaft 12 and the upper shaft 19 will cause the latter to turn rcarwardly, carrying the right-hand holdingarm 21 up from engagement with the righthand sheets, and the inner end of the horizontal member of the turning-arm 14 will ride down the under face of the inclined plate 18, thereby elevating the vertical member of the arm 14. Vhen the horizontal member of this arm has reached the bottom of the plate 18, the vertical member will have been elevated above the upper edge of the leaves and will be in position to enter the space between the outer sheet and the next righthand sheet. \Vhen the turning-arm leaves the plate, it gravitates to its normal position, and the vertical member will thus enter the space between the sheets referred to. The handle is now released, and the spring on the shaft 19 will restore the two shafts 12 and 10 to their normal positions, causing the turning-arm to deliver the sheet taken up on the left-hand side of the book and the right-hand holdingarm to engage with the uppermost right-hand sheet, While the follower or plunger will have been carried back to its outer position.

It will be observed that but a single spring is used, and in the event that the spring should become weakened the return movement of the various parts may be accomplished by turning the handle by hand to the left of the rack.
