MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented May 15, 1917.

Application filed May 10, 1916. Serial No. 96,670.

To all "whom it may concern Be it known that I, Josnrrr B. TURNER, a citizen of the United States, residing at Sulphur, in the parish of Calcasieu and State of Louisiana, have invented a new and useful Music-Leaf Turner, of which the following is a specification.

This invention relates to music leaf turners one of its objects being to provide a se ries of leaf carrying members having sep arate means thereon for supporting the leaves and for backing them so that the leaves will be positively shifted to the right or to the left, according to the direction in which the members are moved.

A further object is to provide conveying devices of novel form adapted to shift the leaf carrying members to the right or to the left respectively, and each of which is so constructed as to engage only one member at a time, thus insuring the turning of a single leaf.

Another object is to provide mechanism of this character which is quick in action, compact and durable and which can be readily set up upon the music ledge of a piano or the like, or upon a music rack or stand, or which, if preferred, can be built into a piano or organ where it can be actuated either by hand or by foot.

With the foregoing and other objects in view which will appearas the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the inven tion.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure l is a front elevation of a portion of a piano having the present improvements combined therewith.

Fig. 2 is a plan view of the leaf turning mechanism.

Fig. 3 is a perspective view of a portion of one of the leaf carrying arms.

Fig. i is a rear elevation of a portion of the mechanism.

Fig. 8 is a perspective view of a support for holding said modified structure to the music ledge.

Fig. 9 is an enlarged front elevation of a portion of the slot in plate t and showing the lever deflecting means, the levers being removed.

Fig. 10 is a section on. line 1010 Fig. 9.

Referring to the figures by characters of reference 1 designates a portion of the case of a piano, the same being provided with a music rack 2 of the usual or any preferred construction. An opening 3 is formed in the case above the rack 2 and extending over this opening is a plate 4- having a longitudinal slot 5.

Arranged within the opening 5 are spaced pivot pins 6 and 7 carried by flanges 8 and 9 extending rearwardly from the upper and lower edges respectively of the opening. The upper portions of the pivot pins are ex tended into an upper deflecting strip 10 the lower surface of which is inclined upwardly and backwardly as indicated at 11, thus to constitute a deflector.

An inclined deflecting strip 12 is mounted on the pins 5 and 7, this strip having its lower end mounted on pin 7 close to the bottom of the slot 5, while the upper end of the strip 12 engages the middle portion of pin 6. This is shown particularly in Figs. 9 and 10.

Plate 4: has a depending tongue 13 provided with an outstanding ear lei from which extends a pintle 15. Mounted for rotation upon the pintle are superposed eyes 16 from each of which projects an L-shaped extension 17 provided at the inner end of an arm 18. All of the arms 18 are in the same horizontal plane and, consequently, the extensions 17 are of different sizes so as to practically nest when the arms are pressed toward the case 1, at one side of the pintle. Each arm is provided with spaced loops 19 depending therefrom and designed to receive a leaf between them. Secured to each arm and between the upper ends of the loops is a spring clip 20 of any preferred construction for gri ping the upper portion of the leaf between the loops, thereby to support the leaf. Upstanding from each arm 18 is an ear "21 and these ears constitute means for limiting the movement of the conveyor arms hereinafter described.

Secured to and extending forwardly from the plate 42 are superposed arcuate guides 22 and 23 between which the arms 18 are designed. to work. If cesired the upper guide 23 may be dispensed with.

Pivotally mounted on the pin 6 is a conveyer lever 21 offset downwardl -J as at 25' close to the pivot receiving opening 26. This lever has a long arm and a short arm, the long arm being above the plane of the short arm and having a laterally extending spring finger 27 the terminal portion of which is inclined upwardly toward its free end, thereby to form a spring catch as shown particularly in. Fig. 5. The pin 7 is extended through another conveying lever 28 comprising a short arm and a long arm, there being a laterally extending spring finger 29 at the free end of the long arm of the lever and which constitutes a catch, the end portion of the finger being inclined upwardly. The two spring fingers 27 and 29 are preferably disposed atright angles to the longitudinal axes of the respective levers.

Mounted back of the plate a are opposed bell crank levers 30 and 31, the lower arm of each of these levers being yieldingly supported by a spring 32 or in any other manner desired. The upper arm of the lever 30 is connected by a rod 33 to the short arm of lever 21*, while the upper arm of lever 31 is connected by a rod 3% to the short arm of lever 28. Rods 35 connect the short arms of the lovers 30 and 31 to pedals 36. It will be understood that the springs serve to hold the lovers 2 1- and 28 normally extended in opposite directions. lVhen these levers are in their normal positions the short arm of lever 2a is extended under the inclined strip 12 so that the spring finger 27 is thus held elevated out of contact with the leaf carrying arms 18 thereunder. lVhen the lever 28 is in its normal position the short arm thereof is extended under and held depressed by the strip 11 so that the spring finger at the end of said lever will thus be held elevated out of the path of any arms 18 which may be disposed thereunder.

Assuming that the sheets of music are supported by the respective clips 20 and between the loops 19 of the respective pairs, and that all of the arms 18 and sheets S engaged thereby are at the right of the structure, as shown in Fig. 1, then the spring finger 27 will be held elevated above the arms 18 and the spring 29 will be held olevated adjacent the opposite end portion of he ope ing Yi' hen it desired to turn one sheet, so as to move it from the right to the left of the apparatis, the lever 30 is actuated by means of one of the pedals 3G and thus pulls, through its rod 33, upon the short arm of Thus said lever is swung in the direction indicated by arrow (a in vFig. 2, and the spring finger on the lever will. ride over and engage the first arm 18. This finger will not engage the second arm 18 for he reason that lever 28 will be limited in its swinging movement by coming against the upstanding ear 21 on the Iii-st arm 18. As soon as the spring linger it) has snapped over the first arm 18, the pedal 36 is released whereupon the spring 32' will return the parts to their initial positions. This will cause the spring finger 29 to pull the engaged arm 18 to the left, carrying with it the sheet engaged thereby and, as the arm 18 approaches the extreme left position, the short arm of lever 28 will be depressed by the inclined strip 11 so that the said finger 29 will thus be supported in an elevated position so as not to interfere with the operation of lever 24:.

Should it be desired to return a shifted leaf to its initial position, the other pedal 36 is depressed with the result that lever 31 will be actuated and will pull through its rod 31 upon the short arm of lever 24:. Consequently spring finger 29 will move downwardly from its elevated position and will swing laterally and engage the first arm 18 in the path thereof and, when the pedal 36 is released, the lever 34 will return to its initial position, carrying said arm 18 with it. As lever 24 approaches its extreme position, the short arm of the lever will ride under and be deflected by the strip 12 so that the spring lingers 27 will be elevated out of engagement with the shifted arm 18.

As before stated, the structure herein described can be built into the case of an instrument. If preferred, however, it can be made a separate attachment to be applied to a music rack. This form of the device has been shown enerally in Fig. 7 wherein the body of the music leaf turner has been in dicated at 37 and the rods 35 have been shown connected to levers 38 designed to be pressed downwardly by hand. These lovers are pivotally connected to the sides of the body as shown at 39 and have their inner end portions working in slots 40 and these inner end portions are connected to the rods 35. In order that the levers 38 may be supported close to the keyboard of the in,- strument, a rack such as shown in Fig. 8 may be employed. This rack includes a frame 11 made of wire or the like and having depending hooks 4:2. The frame 41-1. is

lever adapted to rest upon the music ledge of a piano or other instrument and the hooks 4L2 depend from the ledge and serve to receive the lower edge of the body 37 which is thus held close to the keyboard.

As shown in Fig. 3 the loops 19 are preferably pivotally connected to the arms 18 at the inner ends of the loops as shown at 43 so that it is thus possible for the loops to be swung upwardly and inwardly as indicated by dotted lines in Fig. 3, thus to elevate the loops and permit them to be placed over the leaves to be engaged. Spring fingers 43 are preferably extended downwardly from the end portions of the plate 4 for engaging the cover pages of the sheet music.

What is claimed is The combination with a supporting structure having a transverse slot and a leaf carrying arm mounted for swinging movement upon the structure, of an inclined deflecting member within the slot, a conveying lever pivotally mounted in the slot adjacent the upper end of the deflecting member, yielding means for holding one arm of said lever normally positioned under the deflecting member and the other arm of the lever normally elevated, a finger depending from said elevated arm of the lever and normally supported above the path of the leaf carrying arm, and means for shifting the lever out of its normal position to bring the finger carrying arm of the lever into position under the deflecting member to lower said finger into engagement with the leaf carrying arm.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
