MUSIC-LEAF TURNER.

Specification of Letters Patent.

Application filed December 19, 1908. Serial No. 468,313.

To all whom it may concern:

Be it known that I, NICHOLAS ARMINIO, a citizen of the United States, residing in the borough of Brooklyn, of the city of New York, in the State of New York, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

The object of this invention is to provide a device for turning the leaves of sheet music, etc, which shall be readily applicable to a piano, organ or music stand and shall oper ate with certainty and ease.

The invention will be more fully eX plained hereinafter with reference to the accompanying drawings in which it is illustrated and in which Figure l is a view in front elevation, partly broken out to save space, showing the improved music leaf turner applied to a music stand. Fig. 2 is a view in front elevation of the music leaf turner on a larger scale than Fig. l and also partly broken out.

Fig. 3 is a top view of the parts shown in Fig. 2. Fig. 4: is a detail view in section on the plane indicated by the line H of Fig. 2 with the leaf holders omitted. Fig. 5 is a partial view in front elevation of some of the parts shown in Fig. 2 but in a different position. Figs. 6 and 7 are views in front and edge elevation respectively of a different form of leaf holder.

For convenience in illustration of the in vention it is shown in Fig. 1 of the drawings as applied to an ordinary music stand having a base a and supporting pillar 6 upon the top of which is secured a music rack c. To the latter is secured a plate (Z upon which are mounted the working parts of the leaf turner, the actuating device being shown as a pedal 6 mounted upon the base a and connected by a cord or chain or other suitable connection 6 with the working parts of the music leaf turner. It will be obvious, however, that the plate (Z, with the parts carried thereby, might be secured to the music rack or board of a piano or organ, or a music stand of other character than that shown, and that any other convenient form of actuating device might be employed and suitably connected to the working parts.

In the music leaf turner as shown in the drawings a shaft 7' is mounted in bearings f" secured to the plate (Z and has secured thereto one or more springs f by which it is rotated toward the right or contrary to the direction of movement of the hands of a watch (see Fig. 3). Looselyv mounted on the shaft f is a wheel or drum 9 to which is connected the chain or cord 6' by which the shaft may be rotated toward the left or in the direction of the movement of the hands of a watch and in opposition to the spring or springs F, as hereinafter explained. The wheel or drum 9 also has secured thereto one or more cam pieces it, for a purpose presently to be explained. Secured to the shaft f is a broad flat arm 2' having at its extremity a lip 2" which overlies the leaf holders hereinafter referred to and furnishes a bearing surface against which each leaf holder may be held firmly by a finger 74 adapted to slide longitudinally upon the arm 2' in guides 2' formed therefor. The finger 7c is normally withdrawn by a spring 70 and is projected by the rotation of the cams 72, with respect to the shaft- 7, such cams bearing against the rear or inner end of the finger 7c and working in slot-s formed therefor in the arm 2'. The lip 2" of the arm 2', as will be observed, is somewhat ofiset from the finger is so that there is left between the lip and the finger a space suflicient to receive the shank of the leaf holder as hereinafter explained. Also secured to the plate (Z are guides Z for the leaf holders, such guides being preferably formed by wires which are bent in semicircular or substantially semicircular form, but are slightly eccentric with respect to the shaft f, as clearly indicated in Fig. 3. The leaf holders, which may be of any suitable character, are mounted on the guides Z. As shown in the drawings each leaf holder comprises a thin fiat plate m of metal having holes 77?. for the guides Z and having lugs m by which the plates m are held slightly apart, as shown in F 2 and 3. The edges of theplates m are also slightly beveled, as shown at m in Fig. 2, to facilitate the engagement of the finger 7ttherewith. The shank of each holder carries a part to engage the corresponding leaf.

As shown in Figs. 1 and 2 the shank has pivoted thereon, as at n, a finger n which is Patented Aug. 24., 19M).

suitably formed to underlie the leaf to be turned and to support it during the turning movement, the finger n being pivoted so as to permit it to be turned down out of the way if desired. As shown in Figs. 6 and 7 each shank m is provided with a socket m to receive the tongue 0 of a spring clip 0 which may be made to grasp the lower edge of the leaf or sheet to be turned.

In the operation of the device as shown in the drawings pressure is applied to the pedal 6 and the tension thus created on the connection 6 is transmitted first to the wheel or drum 9, which is thereby turned upon the shaft 7', the arm i being then in its right hand position as shown in Figs. 1 l. The partial rotation of the wheel or drum 9 thus effected causes the cam piece it to act against the rear or inner end of the finger 7c and to project the same to the right, as indicated in Fig. at. As the lip z" of the arm 2' then lies upon the shank of the topmost leaf holder and is slightly ofiset from the extremity of the finger 7s, and as the shank of each leaf holder is slightly separated from the next, as shown in Fig. 3, the extremity of the finger It therefore passes under or behind the shank of the topmost leaf holder, causing such shank to be held firmly and with a broad bearing between the lip and the extremity of the finger. The continued movement of the connection 6 causes the cams to bear against the ends of the slots 2' which thus, with the cams, form stops to limit the movement of the wheel or drum with respect to the shaft, and thereafter the shaft is rotated. The rotation of the shaft causes the arm 2' to swing about the axis of the shaft from the position shown in Fig. 3 to the position shown in Fig. 5 and this movement of the shaft carries the leaf holder over from the right hand position to the left hand position. By reason of the eccentricity of the guides Z the leaf holder is carried clear of the lip z" of the arm 2' as it approaches the limit of its movement toward the left so that the arm is free to be returned to the right by the action of the springs f of the shaft as soon as the tension of the connection 6 is relieved, the finger ]t' being at the same time withdrawn by the spring .1 so that it will clear the topmost leaf holder at the right when the arm reaches its right hand position. Successive operations of the leaf turner will, therefore, move successive leaf holders from the right hand position to the left hand position, causing successive lea-f holders to be turned from the right to the left. To return the leaf holders, one or more, from the left hand position to the right hand position, the arm i is held in the left hand position with the finger 70 withdrawn and the leaf holders are then moved leaves engaged by such from left to right by hand. For convenience in holding the arm 2' in the left hand position a latch 79 is mounted on the plate cl and adapted to engage a lug p on the arm 2.

It will be obvious that various changes might be made in the details of construction, and arrangement of the leaf turner and the invention, therefore, is not to be limited to the precise construction shown and described herein.
