MUSIC-TURNER.

Specification of Letters Patent.

Patented May 19, 1914 Application filed May 29, 1913. Serial No. 770,641.

To all whom it may cone-c1 n Be it known that I, Jnssn E. PooL, a citizen of the United States, and a resident of Vetumka, in the county of Hughes and State of Oklahoma, have invented a new and useful Improvement in Music-Turners, of which the following is a specification.

My invention is an improvement in music turners, and has for its object to provide a device of the character specified for turning the leaves of music, wherein mechanism is provided for turning the leaves in succession operated by the foot of the player, and so arranged that it may be applied to a piano for turning the leaves of the music on the stand, without radical changes in the construction of the piano.

In the drawings :Figure 1 is a partial front view of a piano provided with the improvement, part of the improvement being indicated by dotted lines, Fig. 2 is a transverse vertical scction of the piano, showing the improvement in side view, Fig. 3 is an enlarged front view of the leaf engaging mechanism, Fig. 4 is a section on the line H of Fig. 1, Fig. 5 is a rear view of the operatingmechanism, Fig. 6 is a section on the line 6-6 of Fig. 3, and Fig.7 is a perspective view of the music supporting shelf or plate.

The present embodiment of the invention is shown in connection with the stand 1 of a piano 2, the said stand being arranged in the usual manner above the key board 3 of the piano and mounted to swing, in order that the position of the music may be suited to the player. The stand is provided with a ledge l, near its lower edge, upon which the music may rest. The stand is provided near its upper edge and at approximately the center thereof with an elliptical opening 5, and the said opening is preferably provided with a tubular frame 6, having a beaded flange 7 at its forward edge, overlying the front face of the stand to make a smooth and ornamental appearance.

A frame in the form of an angle bar is secured to the stand 1 on the rear face thereof, the said frame comprising a body 8 and arms 9, extending at a right angle to each other. The body 8 of the frame is immediately behind the opening 5, and the arms diverge from each other and are secured to the stand by means of screws 10, or the like.

The body 8 is provided with a laterally extending lug 11, passing through the open- .the pinion.

ing 5, and the lug is provided with an extension 12 in front of the stand. The turning arms 18 are pivoted to the extension 12, by means of a bolt 14, the said bolt passing downwardly through the arms and through the extension, and being engaged by a nut 15 below the extension. Each of the arms is provided with an enlarged bearing head 16, at the end adjacent to the extension 12, and the said heads arranged in superposed position on the extension and are pivoted thereto by the bolt and nut. Each arm is provided at the opposite end from the hearing head with a music leaf engaging clip. The said clips are spring clips, each con sisting of two clamping jaws 18, pressed together on the leaf by springs 19, and one of the clamping jaws of each clip has a finger piece 17, rigidly connected with one of the arms 13, the other jaw having a finger piece 20, for convenience in opening the clip. Each arm is also provided with a triangular wing or vane 21, near the bearing head and on the upper face of the arm, for a purpose to be presently described.

A pair of pinions 22 and 23 is journaled on the bolt 14:, above the bearing heads, and each pinion is provided with a radial arm 24. A sickle-shaped extension 25 is pivoted to each arm, each of the said extensions extending approximately circumferential of the pinion, with its concave edge toward the pinion, and each of the said extensions is provided with a notch 26 in its convex edge and intermediate its free end and its attachment to the arm 2%. The notches 26 are for engaging the triangular wings or vanes 21, before mentioned. Each extension is engaged by a coil spring 2 1, the spring being on the opposite side of the arm 24 from the extension and acting normally to press the free end of the extension away from A. toothed segment meshes with each pinion, the segment 27 meshing with the pinion 22 and the segment 28 with the pinion 23, and the said segments are pivoted on a journal pin 29 on the lug 11 before mentioned, and each segment is provided with a radial arm 30 and 31 respectively, extending through the opening 5 beyond the inner face of the stand 1.

A link 32 is provided with an angular arm 32 for engaging an opening in the free end of the arm 30, and a similar link 33 is provided with a similar arm 38 for engaging an opening in the inner end of the arm 31. Each link is pivoted at its outer end to one of the arms 84 of an elbow lever 3-i85, and each elbow lever is pivoted to the outer end of the adjacent arm 9 of the frame 8 9, as indicated at 36. A coil spring 37 is arranged between each arm 3d and the frame 8-9, the said springs acting normally to hold the elbow levers in the position of Fig. F. is stirrup 38 is connected to the outer end of each arm 85 by means of a pivot pin 39, and a bearing 40 on a rod i1 is received -between the arms of each stirrup and is pivoted thereto by means of a bolt and nut d2. Each of the rods is provided with an eye. at its lower end for engaging a similar eye on the upper end of the upper section of an extension rod, consisting of upper and lower sections and 44, connected at their meeting ends by a clamp The lower end of the lower section of each rod is pivoted to a pedal 46, the said pedal extending at its front end through an opening 457 in the piano casing and having at the said front end a treadle or foot plate 48. The rear end of each pedal is pivoted to a bracket 49 on the bottom of the piano casing and each pedal is normally pressed upward by a coil spring 50. he the pedal connected with the arm 30 of the segment 27 is pressed downwardly, the said arm will be swung and the segment will be rotated, and will rotate the pinion 22 which meshes therewith. It will be noted from an inspection of Fig. 4 that the convex edge of the extension 25 extends beyond the notch 26 and the said convex edge acts as a cam to prevent the notch engaging the wings or vanes, until the said edge has passed beyond the said wings or vanes. The said edge thus prevents the notch engaging any of the wings or vanes except that of the arm remote from the face of the stand 1. Thus when the said pedal is operated to swing the elbow lever connected with the said arm 30, the pinion 22 will be rotated and the extension will engage the wing or vane 21 of the outermost arm and will swing the said arm to the opposite side of the stand. The leaf of music engaged by the clip on the said arm will also be swung to the opposite side of the stand. l s hen the pedal is released, the spring 50 and the spring 3. will return the parts to their original position. The notch 26 of the extension 25 cannot engage any of the wings or vanes except that of the arm in front. The music leaves may be swung from either side of the stand, the arm 31 of the segment 28 being operated to move the music leaves from left to right, while the arm 30 of the segment 27'is operated to move the leaves from right to left. Rods 51 and 52 depend from a plate 53, held in a rabbet on the under face of the lug 11 of the body 8 of the frame 8-9 and on the underface of the extension 12 of the said lug, and the said rods are connected at their lower ends by means of a cross plate 54. A music supported plate or shelf 55 is mounted on the rods, the said plate or shelf having a central upwardly extending lug 56, provided with a lateral forwardly extending flange 57, having openings through which the rods 51 and 52 slide. The said rods also pass through the plate or shelf 55, and a latch plate 58 is pivoted to the plate or shelf 55 below the same. The latch has a finger piece 59 for operating the same, and has a cam-shaped head 60 at its pivotal end for engaging the rods to prevent movement of the plate or shelf with respect to the said rods. The plate or shelf may be thus adjusted vertically with respect to the leaf engaging mechanism to provide for music leaves of various heights.

By means of the extensible and contractible rod l3 l l, the pedal may be arranged at any desired height in the casing and the connection may also be adjusted to compensate for wear. Each of the segments 27 and 28 is provided with an arc-shaped slot 61, for engagement by a pin 62 on the lug 11 before mentioned, to limit the swinging movement of the segments. The springs 2 f hold the extensions with their convex edges in engagement with the wings or vanes and permit the extensions to yield toward the pinicns on the return movement in order that the notch or the catch behind the notch may pass the wings or vanes.

I claim Tn combination with a piano having a music stand, of a frame comprising a body and diverging arms, and adapted for attaclnnent to the rear face of the music stand, said frame having a lug extending laterally from the body and adapted to extend through an opening in the stand, turning arms pivoted to the lug in front of the stand for swinging movement from side to side of the stand, means in connection with the lug for swinging the arms in either direction, an

elbow lever pivoted to each arm of the frame, each elbow lever comprising an arm connected with the turning mechanism for swinging the leaves toward that side of the stand, and an arm extending laterally in the opposite direction from the frame, a stirrup pivoted to the last-named arm of each elbow lever, and an expansible and contractible rod connecting each stirrup with the adjacent pedal and pivoted to the stirrup to permit the stand to swing with respect to the rod.
