UNITED STATES ANGELO DE STEFANO, OF RIDGEFIELD PARK, NEW JERSEY.

MUSIC-LEAF TURNER.

Application filed March 8, 1918.

To all tf1/omit may concern Be it known that l, ANGELO Dn STEFANO, a citizen of the United States of America, residing at Ridgeiield Parli, in the county of Bergen and State of N ew Jersey, have invented new and useful improvement-s in Music-Leaf Turners, of which the following is a specification.

This invention relates to improvements in music leaf turners and seeks for its principal object to simplify and reduce the expense of manufacture of devices of this character, the same employing a minimum number of parts, which effectively operate at all times to accomplish a purpose for which they are designed. l

Another obj' ect of the invention is the provision of a music leaf turner which is so constructed as to allow the arms which carry the sheets, to be readily turned in either direction independently of the mechanism for operating the same.

Another obi ect of the invention is the provision of a music leaf turner comprising plurality of swinging arms arranged in superposed relation, an actuator arranged above said arms, means for transmitting motion to the actuator and a spring pressed trigger vertically movable through said actuator and provided at its lowerniost end with means for successively7 engaging the arms and correlating the same with the actuator' for turning the leaves successively.

lith these and other objects in view the invention resides in the novel construction, combination and arrangement of parts, fully described and pointed ont in the following description and claims and illustrated in the accompanying drawings in which- Figure 1, is a front elevation of the device.

Fig. 2, is a horizontal section on the line 22, of Fig. 1, looking in the direction indicated by the arrows.

Fig. 3, is a vertical section on the line 3 3, of Fig. 1, looking in the direction indicated by the arrow.

Fig. 1, is a diagrammatic view of the arms and the trigger.

Figs. 5, G and 7 are detail views illustrating the manner in which the arms 14 are moved from one side to the other of the device successively.

Referring to the drawings, 10 designates Specification of Letters Patent.

Serial No. 221,239.

a base plate w iich is provided with the pivoted clamp 11, the same being designed as a means for clamping the device to the stand or other article to which the device is to be applied, and which also serves as a means for positioning the hook or sheet music thereon. Secured to the plate is a casing` 12, which is provided with a pivot pin 13, extending vertically therein, upon which are mounted for swinging movement the arms which are provided at their outer ends with any suitable clamping means 15, for engagen ent with the music leaves. Each arm le is provided with an enlargement 14a the purpose of which will appear hereinafter. Mounted above the arms 14, on the pin 13, is an actuator 16, which is provided with teeth 17, and an outwardly extending arm 'ng a sleeve 19, through which a trigger pm 20, is adapted to slide. The pin is provided at its lower end with an enlarged head 21, having a reduced lue` 22, pr jecting downwardly therefrom and the sleeve is provided with enlarged bore at its lower eX- tremitjf forming a shoulder 23, therein between which and the head 21, is inserted a coi ed spring 2e?, whereby the trigger is norll projected toward the arms 14, as is shown in Fig. 3 of the drawings. The lug 22 is adapted to ride over the enlargement 14: of the arms. The lug 22 is of a length equal approximately to the thickness of either of said arms. rlherefore it is impossible to move more than one arm at a time. rllhe trigger is provided at its upper ing portion 25, and has end lith manipul a stesl pin 26 therein, which is adapted to engage the upper extremity of the sleeve whereby the trigger may be locked in an inoperative position when desired. Extending transversely of the easing 12, is a bar 27. provided with rack teeth 2S, for engagement with the 17, on the actuator. One eX- tremiti7 '..ic lar 2T, is reduced as at 29, to form a snoulder 3G, between which and the side of the casing is interposed a coiled s V nag; 31, the purpose of which is to normally project the bar 27, in one direction. The opposite extremity of the bar is pro- .'dcd with an opening 52- in which is received a HeXible shaft 33, which is )rovided with an operating` head 34. This operating means may also be used in com ysation with a foot pedal and may be positioned at any point within convenient reach of the musician. si stop member 35, is provided adjacent the pin 13, and projects upwardly through the bottom of the casing where it is adapted to be engaged by the arms in either direction to limit the movement thereof. This stop positions the arms with relation to the trigger to cause the same to positively bring` the lug 22, into proper place. rlhe lower side and front walls of the casing` are slotted as at 36, to provide a working space for the arms and the upper wall of the casing` is provided with an arcuate slot 37, which receives and guides the upper ez:- tremity et the sleeve 19.

To turn the leaves or sheets of the music to be played individually, the operating head 34: is moved toward the bar 227 and this action through the intervention ot the parts 17, 18 and 19 cause the pin 2O to move in an arc. lnasmuch as the lug 22, in its normal position, is in engagement with the uppermost arm 1e, the same will be caused to move to its other extreme position. Upon removal oit pressure on the head 34, the spring` 31 will Yfunction to cause the return movement of the pin 2O and in the return movement of the pin 20, the lug 22 will ride over the enlargement lla of the next uppermost arm 14l until it clears the back edge thereof, when the spring' 24 will impart a .downward movement to the pin 20 causingl the lug 22 to be positioned behind the arm 141. The head 21 limits the downward movement of the pin 20. lt will be understood that the pin 20 is capable oi reciprocatory, arcuate and turning' movements.

In Fin: 5 one of the arms 14 is shown about to be moved to an opposite extreme position from over the alined arms beneath.

Fig. 6 is a sectional view taken on the line 6 6 or" Fig. 5. Fig. 6 shows the relative disposition of the parts as shown in 5.

Fig. 'Y shows the lug 22 disposed behind the arm 1%2 next lowermost to the arm 1l being moved as in Fig. 5. rlhe lug 22 never rode off of the enlarged part 14 of the arm 142 until it arrived at the baci; edge of the arm 142, at which point the said lug is projected down behind the arm 1&2 by the spring 2li. Such operation is repeated until all of the arms have been moved by the mechanism, when they are returned by hand to their other extreme positions.

While I have shown and described a simple and preferred form oi? the invention, l do not care to be limited to the exact details therein exhibited but desire to reserve the right to make such changes and alterations as liall within the scope of the appended claims.

lWhat l claim is 1. A music leaf turner including a pivot, a plurality or" superposed leaf turning arms loosely mounted on said pivot, means for effecting the movement of said arms singly in succession including a flexible thrust member and a spring pressed pin havinp` a lug` which is engageable with said arms, and a shoulder embodied by said pin whereby the same is limited in its downward movement.
