Application filed September 30, 1908. Serial No. 455,431.

To all whomtt may concern:

Be it known that I, EDWARD E. VAN DINE, a citizen of the United States, residing at Elmira, in the county of Chemung and State of New York, have invented certain new and useful Improvements in Music- Turners, of which the following is a specification.

This invention'relates to music sheet holders and refers especially to music leaf turners.

An object of this invention is to construct a device for holding sheets of music which will turn the same very quickly at the will of the operator for the purpose of facilitating the reading of the music by obviating the necessity of employing the hands for the manipulation of the sheets thereof.

Another object of this invention is the provision of means for accomplishing the above enumerated results which are simple, easy and positive of action, producing a mechanism which will be more adaptable to the public use than any device heretofore devised.

Other objects and advantages will be apparent from the following description, and it will be understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts, in the sev eral views, Figure 1 is a front elevation of the complete device, Fig. 2 is a top plan view of the same, Fig. 3 is a detailed view, an enlarged view of the operating disk and arms actuated thereby, Fig. 4 is a transverse section through the disk, showing the position of the operating spring therefor, Fig. 5 is a detailed view of the pawl disposed upon the disk for engagement with the operating arms, Fig. 6 is a detail view of the lever and connected parts in side elevation.

Referring now to the drawings, 10 designates a base which intermediately supports a vertically disposed tube 11 which loosely carries upon its upper extremity a disk 12. The disk 12 is secured to one end of a coil spring 13 which surrounds the tube 11 directly beneath the disk 12 and is rigidly engaged thereto at its opposite extremity. The disk 12 carries a sleeve 14 upon its opposite sides of the tube 11 are backs 16 and 17 against which sheets of music are adapted to rest and which also serve as a support for a trip lever 18 which is disposed upon the upper edge of the back 16 immediately beneath the disk 12. The trip lever 18 is provided with a depending rod 19 which extends downwardly through the tube 11 where it is pivotally secured to the middle of a lever 20 hingedly supported at its rear extremity to the base 10 and which extends forwardly where a disk attachment 21 is positioned for the purpose of actuating said lever. The rod 19 is provided with a spring 30 beneath the lower face thereof for the purpose of tensionally holding the same in an upward position, which spring 30 is carried upon the upper edge of the back 16 directly beneath the rod 19 and serves the purpose of normally holding the same in an upward position to lock the disk 12 at each complete revolution.

Disposed about the sleeve 14 are a number of operating arms 22 which extend from the sleeve 14 and carry at their outer extremities depending clamps 23 for the purpose of engaging the upper edges of sheets of music disposed against the backs 16 and 17. The disk 12 is apertured near the outer edge thereof in which is pivotally disposed an automatic catch 241 which is adapted to en gage the foremost arm 22 when the trip lever 18 is engaged against the disk 12. The engaging member 2 1 comprises a small portion of metal which has a rectangular aperture in its upper edge to form shoulders therein for the reception of the arms 22 and it is also provided with a beveled forward upper edge 25 to allow the member to pass beneath the arms 22 which are disposed backwardly on the device and to prevent the engagement of the same in the member 241-. A spring 26 is mounted about the pivot pin 27 for engagement with the member 2% of the disk 12 for the purpose of normally and tensionally holding the same in an upward position.

It will be noted from the top plan view of the device, that the arms 22 are flattened at their inner extremities and are curved centrally proportionately to their relative positions from the sleeve it With this construction the arms 22 are disposed in parallel and a. second clasp 28 may be employed intermediately disposed upon the rms 'l' t r 5 engagementwith the opposite sides or the 5 the sheets, it is necessary only to depress the member 21 which draws the lever 20 downwardly and releases the trip 18 through the connecting rod 19 and allows the spring 13 to rotate the dish halt a revolution when the engaging member will be stopped by the bracket 31. As the engaging men'iber 2+ is released and allowed tree circular n otion it passes to wrardly beneath the a rnis allon ing the beveled portion 23 only to contact 5 with the lower faces of the arms until the last or fore-most arm is reached. when the beveled taco portion is released and allowed upwariil movement under the ten sion of the spring 26 to ei'igage the shoulder formed in the upper ed e thereot about the foremost arm 22.

"What is claimed isz t. In a music leaf turner the combination of a base, backs upwardly extended from said base, a tube ipi'ardly extended from said base between said backs, a dish pivotally secured about the upper extremity of said tube, a spring carried by said tube and extended about the same connected to said dish, a i lurality of arms pirotally and concentrically disposed above said dish, a spring disposed against said disk, an engagement member disposed upon the upper face oil said disk to carry said spring tor abutment with said arms tor the purpose of actnatiiw said arms sepa 'ately upon the rotation oi said dish, a rod disposed through said tube t'or locking engagement with said dish, a spring carried by one or said backs engaged with said rod to normally hold the same in engagement with said dish and a ever pirotally disposed upon said base and ronuerd to said rod for depressing the same at ti t.

in a music leaili turner the combination with a base and ba -l s upwardly disposed on said base, of a tube carried by said base pd ,itioned between said backs, a disk pirotally disposed about the upper extremity at said tube, a spring disposed between said tube and said dish for rotating said dish, a pin 'a ity of radially extended arms disposed on said tube above said disk, an ttlgttilltittlilmember carried by said dish for locking en. g ap ement with the foremost of said arms to rotate the same upon the artuat on o'l said dish, a lever :arried. by said base, a rod disposed through said tube having locking en gg'einent with said disk and connected to said lever for releasing said d q and a stop upwardly OXlZQl'ltlitl from one of said backs tor preventing the complete rotation at said arms.

In testimony whereof it allix my signature. in presence oi two witnesses.
