ROBERT C. ELLIOTT, OF TERRE HAUTE, INDIANA.

MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent N0. 769,155, dated September 6, 1904.

Application filed December 8, 1903. Serial No. 184,261.

To all whom it may concern.-

Be it known that 1, ROBERT C. ELLIOTT, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Music-Leaf Turners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to turners for sheetmusic; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a front view of the music-leaf turner. Fig. 2 is a partial rear view of the same. Fig. 3 is an end view of the same.

A is a desk or back-plate for the sheet-music to rest against.

E is a stationary clamping-jaw secured to the middle part of the desk.

C is a slidable clamping-jaw provided with guide-pins c, which slide in guide-slots Z) in the desk A.

D is a bar for operating the sliding jaw and provided with a finger-piece (Z, which projects slightly at one end of the desk.

E is a spring which is secured to the back of the desk and which engages with a pin 0 on the slidable jaw and presses it toward the said stationary jaw. The middle part of the music Where folded is clamped between the two said jaws, and the bottom edges of the leaves rest on the ledges a, which project at the bottom of the desk.

F represents arms which prevent the cover portions of the piece of music from being turned. A lug f projects downwardly at each end of the desk and has a spring Gr secured to it. The arm F has a pivot f, which pro jects from it at a right angle and which is journaled in a bearing g on the end of the said spring. The arm is formed of a piece of wire, and the pivot is formed by bending it. The end of the piece of wire is rebent beyond the pivot to form a heel g, which is arranged parallel to the said pivot. This heel bears against the desk or the lug projecting there- (No model.)

from, so that the spring presses the free end of the arm against the cover-sheet.

H represents the turning-arms, which are pivoted on a pin 7t, secured to the middle portion of the lower part of the desk. Each turning-arm has a spring-clip It of any approved construction for engaging'with a leaf of music, and this spring-clip is secured to the free end of the said arm.

I represents the two levers for operating the turning-arms. These levers are provided with eyes I, which are slidable longitudinally on the arms H. Each lever I is secured to the upper end of a shaft i, which is journaled in a bearing secured to a bracket J. The bracket J is secured to the middle part of the bottom of the desk A, and j is a shaft carried by the lower part of the said bracket. A pinionK is secured on the lower end of each shaft t, and m and m are two pairs of toothed segments, said segments being arranged one on each side of each of the said pinions and gearing into their teeth. Each toothed segment is provided with a bearing a, which is journaled on the shaft 7' and provided with a finger-piece N for operating it. In order to facilitate the construction of the device, each finger-piece is formed separate from the segment to which it pertains and is provided with a separate bearing 91'. The stems or shanks of the toothed segment and of the finger-piece are secured together, so that the bearings 72 and '21- project in opposite directions.

0 represents angle-shaped guide-plates, of spring metal, which are secured to the bracket J and which bear against the backs of the toothed segments, so that the said segments are held in gear with the toothed pinions.

P is a cover-plate which is hinged to the top part of the bracket J and which protects the segments and pinions from injury.

The back of the desk is provided. with any approved clamping or fastening devices for holding the desk connected to any convenient support. R is a dovetailed socket secured to the back of the desk and which forms a slipjoint for engaging with the said clamping or fastening devices.

The music is held in position by the clamping-jaws, as hereinbefore described, and the leaves to be turned are inserted in the springclips. The leaves are turned over by depressing one of the finger-pieces N. These fingerpieces are arranged in pairs, and one turns the leaf in one direction and the other in the opposite direct-ion. The whole device is very simple and compact and is not liable to get out of order.

What I claim is 1. In a music-leaf turner, the combination, with a desk provided with a stationary clamping-jaw at its middle part and guide-slots, of a slidable clamping-jaw provided with guidepins which slide in the said slots, an operating-bar for the said slidable jaw provided with a finger-piece which projects at one end of the said desk, a spring which presses the said jaws together, a leaf-turning arm pivoted to the said desk in line with the said jaws, an operating-lever pivoted to the said desk out of line with the said jaws and provided with an eye which is slidable longitudinally on the said turning-arm, and operating mechanism for turning the said lever back and forth.

2. In a music-leaf turner, the combination, with a desk provided with means for supporting the music, and a bent spring secured to the lower part of the said desk; of a retaining-arm having a bearing at its lower end which is pivoted in the free end portion of the said spring and having also a heel arranged parallel to the said pivot-bearing and engaging with the desk, a leaf-turning arm pivoted to the said desk to one side of the said retaining-arm, an operating-lever pivoted to the said desk out of line with the pivot of the said leaf-turning arm and provided with an eye which is slidable on the said leaf-turning arm, and operating mechanism for turning the said lever back and forth.

3. In a music-leaf turner, the combination, with a desk provided with means for supporting the music, and a bent spring secured to the lower part of the said desk and provided with a bearing at its free end; of a retainingarm formed of wire and having a pivot at its lower end bent at a right angle to its main portion and journaled in the said bearing and having also a rebent portion arranged parallel to the said pivot and forming a heel which is pressed against the desk by the said spring, a leaf-turning arm pivoted to the said desk to one side of the said retaining-arm, an operating-lever pivoted to the said desk out of line with the pivot of the said leaf-turning arm and provided with an eye which is slidable on the said leaf-turning arm, and operating mechanism for turning the said lever back and forth.

4. In a music-leaf turner, the combination, with a desk provided with means for supporting the music, of a leaf-turning arm pivoted 1 to the said desk, an operating-lever provided with an eye which is slidable longitudinally on the said turning-arm, said lever being pivotally supported from the said desk out of line with the pivot of the said operating-lever, and operating mechanism for turning the said lever back and forth.

5. In a music-leaf turner, the combination, with a desk provided with means for supporting the music, of a pivoted leaf-turning arm, a vertical shaft, an operating-lever secured to the said shaft and engaging with the said arm, a. toothed pinion secured to the said shaft, toothed segments engaging with the said pinion, and angle-shaped guide-plates of spring metal which bear against the backs of the said toothed segments.

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

ROBERT C. ELLIOTT.
