MUSIC-LEAF TURNER.

Specification of Letters Patent. Patented J an. 15, 1918.

Application filed September 21, 1914. Serial No. 862,763.

To all whom it may concern:

Be it known that I, GEORGE E. MOWERY, a citizen of the United States, residing at Lancaster, in the county of Fair-field and State of Ohio, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

MIy invention relates to new and useful improvements in a music leaf turner, and has for its primary object the provision of such a device which may be easily attached to a piano or other similar musical instru ment.

A further object is the provision of a leaf turner which can be easily attached to the various leave of a book of music.

With these and other objectsin view the invention consists in the novel details of construction and arrangement of-parts which will be more clearly understood from the following description and drawings, in which,

Figure 1 is a front elevation.

Fig. 2 is a longitudinal vertical section.

Fig. 3 is a longitudinal section on the line 3-3-of Fig. 2.

Fig. 4 is a transverse vertical section on the line H of Fig. 2;

Fig. 5 is a fragmental top view of the leaf holders. 1

Fig. 6 is a detail of the operating arm. Fig. 7 is a detail of the leaf holder, and

Fig. 8 is a detail of the attaching mecha-- nism with the spring broken away.

Fig. 9 is an end view of the upper plate shown in Fig. 8. Fig. 10 is a plan view of the upper plate of Fig. 8 showing a detail formation thereof.

Fig. 11 is a perspective view of the adjustable portion of the knee operated rod with the parts disassembled.

In the drawings, the numeral 1 indicates a piano or similar instrument and 2 the keyboard thereof. Secured above the keyboard preferably on the music holder of the piano is a boxing 3 having the longitudinal grooves A therein. This boxing is also provided with the back plate 5 and a Vertical opening 6. A gear 7 is received in the vertical opening 6 and has a rod 8 secured thereto and said rod 8 has a leaf-engaging arm 9 secured thereto. A similar gear 10 is loosely mounted upon the rod and has an extension 11 to which is secured a leaf-engaging arm 12. Athird gear 13 is loosely mounted upon the extension of the second named gear and this gear 13 has an extension to which is secured a leaf-engaging arm 14:. All of the leaf-engaging arms are similarly constructed so I will just describe one as shown in detail in Fig. 7 of the drawings.

In this figure I have shown the bottom gear 7 secured to the shaft 8 and the leafengaging arm 9 secured to the shaft. This arm 9 has an extension 15 secured thereto and the-loops 16 surround the arm 9 and extension 15 for holding them in sliding relation. Secured to the arm 9 are the vertical rods 17 and secured to the extension 15 are the vertical rods 18. The vertical rods 17 and 18 are adapted to engage each side of a leaf of music, the rods 18 engaging the outer edge and the rods 17 the inner portion.

A slidable plate 19 is mounted within the boxing 3 and is provided with the vertically and longitudinally spaced rowsxof teeth 20, 21 and 22, the teeth 20 adaptedto engage the small gear 7 when the plate is operated, the teeth 21. adapted to engage the gear 10 and the teeth 22 adapted to engage the gear wheel l3. These teeth extend and operate within the longitudinal grooves 42 formed in the boxing.

Secured to each end of the piano by means" of a plate 23 is a vertical rod 24 and slidable on the rod 21 is an extension rod 25 which carries a plate 26 on the top thereof. A coil spring 27 is mounted between the plates 23 and 26 and surrounds the rods 24 and 25. A roller 28 is mounted in the end of the plate 23 and a roller 29 mounted in the end of the plate 26. The plate" 26 is provided with a slotted extension 30 which is adapted to straddle a headed stud 31 on the ends of the piano.

A rope or cable 32 is secured to each end of the plate 19 and passes over the rollers 29 and 28 and'under the keyboard of the piano where it is attached, as shown. at 33, to the end of the operating rod 34. This operating rod is secured to the underside of the piano keyboard by means of the bracket 35 and is pivotally connected thereto at 37 and is provided on the opposite end with a knee engaging loop 36 formed of spring metal. The operating rod 34 is formed in two sections and may be adjusted, one of the sections having up-turned ears 37 which guide this section 111 its adjustment along the other.

To permit of adjustment, this section is provided with an elongated slot 38 through which passes the securing element 39.

Having fully described the invention in detail I will now proceed to describe the operation. In its initial position the sliding plate 19 and the gears 7, 10 and 13 with the leaf-engaging arm secured thereto will be in the position shown in Fig. 2 of the drawing. When it is desired to turn the leaves the knee is engaged in the loop 36 and by moving to the leftthrough means of the rope or cable 32 will slide the plate 19 longitudinally of the boxing and the teeth 22 engaging the small gear 13 will turn the leaf-engaging arm ll, thereby turning one leaf of the music. By the further sliding of the plate the teeth 21 will engage the gear 10, thereby turning the arm 12. By a still further movement of the plate the teeth 20 will engage the small gear 7 and turn the arm 9. It will thus be seen that by the operation of the plate through means of the operating rod' 3% the teeth will successively be brought into engagement with the various gears, whereby the leaf-engaging arms are turned for turning the various leaves or sheets of muslc.

The operating rope or cable 32 is held taut or under tension by means of the two sliding rods 24 and 25 which are forced outwardly by means of the coil spring 27. The rope or cable passes over the rollers 28 and 29, thereby preventing any friction.

The forked end 30 on the plate 26 engaging the headed stud 31 on the end of the piano forms a guide for'the upper plate 26. By reversing the movement of the plate the arms are returned to their normal or first position.

By having the leaf-engaging arms adjust able the turner may be used with music in which the sheets are of greater or less width.

Having fully described my invention what I'claim as new and desire to secure by Letter's Patent is z- 1. The combination in a piano, of a plate secured thereto, a vertical rod secured to the plate, a sliding rod secured to said first mentioned rod, a plate secured to the sliding rod, rollers mounted in each of the plates, a spring between the two plates, a :boxing,

a plurality of leaf-engaging arms mounted on the boxing, a sliding plate for operating the arms, a rope secured to the plate and passing over the rollers on the plates at the end of the piano, and a rod pivotally secured to the piano and attached to the rope, said rod having an inverted U-shaped loop secured thereto.

2. The combination in a piano, of a plate secured thereto, a vertical rod secured to the plate, a sliding rod secured to said first mentioned rod, a second plate secured to the sliding rod, an extension at right angles to said second plate provided with a slot to straddle a projection on the piano end, rollers mounted in each of the plates, a spring between the two plates, a boxing, a plurality of leaf engaging arms mounted on the boxing, a sliding plate for operating the arms, a rope secured to the sliding plate and passing over the rollers on the plates at the ends of the piano, and a rod pivotally secured tothe piano and attached to the rope, said rod having an inverted U-shaped loop secured thereto.

3. The combination in a piano, of a plate secured thereto, a vertical rod secured to the plate, a sliding rod secured to the said first mentioned rod, a second plate secured to the sliding rod, an extension at right angles to said second plate provided with a slot to straddle a projection on the piano end, rollers mounted in each of the plates, a spring between the two plates, a boxing, a plurality of leaf-engaging'arms mounted on the boxing, extensible sections carried by the said arms, leaf holders on the leaf-engaging arms and on the extensible sections, asliding plate for operating the arms, a rope secured to the sliding plate and passing overthe rollers on the plates at the ends of the piano, and a rod pivotally secured to the piano and attached to the rope, said rod being adjustable in its length and carrying on its outer terminal an inverted U-shaped loop.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGE E.MOWERY.
