UNITED STATES PATENT OFFICE.

THOMAS F. BURNS, OF OKLAHOMA, OKLAHOMA, ASSIGNOR OF ONE-HALF TO ROBERT P. CRUSE, OF ANADARKO, OKLAHOMA.

MUSIC-TURNER.

Application filed September 1, 1916.

To all whom it may concern:

Be it known that I, THOMAS F. BURNS, a citizen of the United States, residing at Oklahoma, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Music- 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 a music leaf turner and has for its primary object the provision of means, whereby the leaves of music may be readily turned as they are played or read.

Another object of this invention is to pro-' vide a base or casing carrying a plurality of "leaf supporting arms, having means attached thereto, whereby one arm may be swung about a vertical axis at a time to turn the leaf of music carried thereby.

Another object of this invention is to provide means for returning the leaf supporting arms to their normal position after the leaves of music have been once turned.

A further object of this invention is to provide means upon. an operating arm and actuated by a cam to grip the uppermost leaf supporting arm to turn it upon actuating the operating arm.

A still further object of this invention is the provision of a music leaf turner of the above stated character, which shall be simple, durable and efficient, and which may be manufactured and sold at a comparati ely low cost. 7

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as. will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure l is a top plan view of a music Specification of Letters Patent.

Serial No. 118,061.

leaf turner, constructed in accordance with my invention, having the top of the base or casing removed,

Fig. 2is a longitudinal sectional. View taken on the line 22 of Fig. l,

i Fig. 3 is a fragmentary front elevation partly in section with the leaf supporting arms removed, illustrating the means of actuating the operating arms,

Fig. 4: is a fragmentary enlarged vertical sectional view illustrating the manner of mounting cams and ears upon the base or easing,

Fig. 5 is a. detail sectional view illustrating the means of pivoting the leaf supporting arms to the base or casing,

Fig. 6 is a detail view partly in section illustrating one of the operating arms, and

Fig. 7 is a detail sectional view taken on the line 77 of Fig. 1.

Referring in detail to the drawings, the numeral 1 indicates as an entirety a base or casing, consisting of a rear plate 2 and a front plate 3, which plates are spaced apart by side strips 4. The front plate 3 being provided with an elongated slot 5 adjacent its lower edge to allow for a plurality of leaf supporting arms 6 to extend through the front plate 3.

A bracket 7 secured to the rear plate 2 adjacent the elongated slot 5 has formed upon its upper edge an ear 8 to which is pivotally secured the leaf supporting arms 6. Each of the leaf supporting arms 6 has a clasp 9 secured to their free ends and each clasp consists of a bottom plate 10 and a top plate 11. The top plate 11 being hinged to the bottom plate 10 as illustrated at 12 and the top plate 11 is normally held into engagement with the bottom plate 10 by means of a leaf spring 13 so as to tightly clamp a leaf of music between the top and bottom plates 10 and 11.

A pair of relatively spaced bearings 14 are secured to the rear plate 2 of the casing or base 1 and are positioned upon each side of the bracket 7 and have secured therein a shaft 15 which has each end squared to fit squared openings in the bearings 14: to PI'B' the sleeve 19 and has secured thereto a rod.

22 which has a ring 23 formed upon its free end. The ring 23 surrounds a cam 24 secured to the shaft 15.

Each of the leaf supporting arms 6 have pivoted thereto a bell crank arm 25 which is normally spring pressed by a leaf spring 26 for holding the bell crank arm 25 in a position so that one arm portion thereof extends at right angles to the leaf supporting arm 6. lVhen the operating arm 17 is swung from a vertical position to the right to occupy a substantially horizontal position, the sleeve 19 is caused to slide in the direction of the free end of the operating arm by the cam 24 and as the operating arm assumes a substantially horizontal position and the beveled end 18 thereof has passed below the uppermost bell crank arm 25 on the uppermost leaf supporting arm 6, the extension 20 will be overlying the free end of the operating arm thereby clamping the respective bell crank arm between the extension 20 and the free end of the operating arm 17. As the operating arm 17 is swung about the shaft 15 to turn the up permost leaf supporting arm 6, the sleeve 19 will be drawn downwardly upon the operating arm 17 when the operating arm 17 assumes a horizontal position upon the opposite side or left hand side of the base 1. to free the bell crank arm 25 therefrom, thereby allowingthc operating arm 17 to return to a substantially horizontal position upon the right hand side of the base to grip the next adjacent bell crank arm 25 of the next adjacent leaf supporting arm 6.

A plurality of pins 27 are formed upon the rear plate 2 of the base or casing 1 and arranged in parallel rows to form a guard to slidably receive a rack bar 28. The rack bar 28 is in mesh with the gear 16 upon the operating arm 17 A link 29 is pivoted to one end of the rack bar 27 and to a bell crank lever 30 pivoted to the rear plate 2 of the base 1 as illustrated at 31. A coil spring 32 is secured to one of the arm portions of the bell crank lever 30 and to the rear plate 2 of the base or casing 1. A link 33 is pivoted to the bell crank lever 30 and to an operating arm 34 which is slidably secured in brackets 35 carried by the rear plate 2 of the base or casing 1 and has its Slidable upon the free end of the free end bent to form a finger grip 36. By pushing or pulling downwardly upon the finger grip 36, the rack bar 28 is caused to slide between the parallel rows of pins 27 rotating the gear 13, swinging the operating arm 17 about a vertical axis, turning the leaf supporting arm which is attached there to in the manner heretofore described and swinging same about a vertical axis against the tension of the spring 32. When the finger grip 36 is released, the rack bar 28 returns to its normal position under the influence of the spring 32, thereby returning the operating arm 17 to its normal position, ready to turn the next adjacent leaf supporting arm.

A gear 37 is journaledon the shaft 15 and has formed thereon an operating arm 38 which normally extends in the opposite direction from the operating arm 17. sleeve 39 is slidably secured to the free end of the operating arm 38 and has an eXtension 40 formed thereon for overlyingthe beveled end 41 thereof. A rod 42 is secured to the sleeve 39 and has a ring 43 formed thereon for surrounding the periphery of a cam 44 for causing the sleeve 39 to slide downwardly upon the operating arm 38 when swung to a parallel position with the operating arm 17 when it is in its normal position. A rack bar 45 is slidably secured to the rear plate 2 of the base or casing 1 by rows of parallel pins 46 and has pivoted thereto a rod 46 which is in turn pivoted to a bell crank lever 47. The bell crank lever 47 is pivoted to the rear plate 2 of the base or casing 1 as illustrated at 48 and has secured thereto a coil spring 49 which is in turn connected to the plate 2 of the base or casing 1. A link 50 is pivoted to the bell crank lever 47 and to an operating arm 51 which slides in the brackets 35. The free end of the operating arm 51 is bent to form a finger grip 52. hen all of the leaf supporting arms 6 have been turned, they rest upon the extension 40 and to return them to their normal or initial position, the finger grip 52 is pulled, causing the rack bar 45 to swing the arm 38 to the right of the device, depositing the bell crank levers 25 upon the extension '20 of the sleeve 19. As the arm 38 moves to the right side of the device, the cam 44 causes the sleeve 39 to move downwardly upon said arm, disengaging the extension 40 from the bell crank levers 25, allowing the arms 6 to fall to their initial or normal position. By manually rocking all of the bell crank levers 25 on their pivot, they will pass the extension 20, leaving the arm 17 or extension 18 thereon disposed thereover. The weight of the arm 17 then being on the outermost bell crank lever 25 Wlll cause the same to move on its pivot for admitting the bevel face of the extension 1.8 to pass the same and the respective spring 26, connected to the bell crank lever 25, forces it between the extensions 18 and 20, hus positioning the device for operation.

An operating rod 53 is slidable in the brackets 35 and has its free end bent to form a finger grip 54 and has its other end pivoted to a link 55. The link is pivoted to a bell crank lever 56 which is pivoted to the rear plate 2 of the base or casing l as illustrated at 57. An outwardly extending extension 58 is formed on the free end of the bell crank lever 56 of sufficient length to engage all of the bell crank levers 25 but the outermost one when all of the leaf supporting arms 6 have been turned, whereby upon pulling or pushing downwardly upon the finger grip 54:, the extension 58 will rock the, bell crank levers 25 that are in engagement therewith, so that upon moving the arm 38 to the right by pulling on the finger grip 5a, the outermost or last leaf-support ing arm 6 that was turned from its initial position, will be engaged by the extensions L0 and 41 and returned to its initial position, providing means whereby the chorus of the music can be replayed and which is usually the last sheet of the series of sheets to a piece of music.

In operation, the device is placed vertically upon a music rack and the leaves of music are each received by the separate clasps 9 carried by the leaf supporting arms 6. When it is desired to turn the first leaf of music, the finger grip 36 is pushed or pulled downwardly causing the operating arm 17 to engage the uppermost bell crank arm 25 and swing the respective leaf supporting arm secured thereto to a substantially horizontal position upon the left hand side of the base 1, thereby bringing the next adjacentleaf of music in view so that the same may be played or read by a person. After the leaves of music have been all turned, they may again be returned to their normal position by pressing or pulling upon the finger grip 52, causing the operating arm 38 to return the leaf supporting arms 6 to their normal position.

While I have shown and described the preferred embodiment of my invention, it will. be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.
