MUSIC-LEAF TIIRNER.

Application filed October 4, 1915.

To all whom it may camera.-

Be it known that I, EDWARD J. HAWKINS, a citizen of the United States, residing at Solvay, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Music- Leaf Turners, of which the following is a specification.

The present invention relates to improved music leaf turners designed for turning sheet music and operated by pedal mechanism.

The primary object of the invention is the provision of a device of this character that is simple in construction and operation, but eflicient in performing its functions.

The device is designed to be adjustable for different conditions, in order that the music rack, of which the leaf-turner forms a co-acting element, may be located in desired position above the key board of the piano or organ with which the device is utilized. By theutilization of pedal actuated instrumentalities, I am enabled to operate the leaf turner and permit the player or artist to use the hands freely for playing purposes only. Provision also is made for turning back one or more leaves of music when desirable or necessary, without recourse to the use of the hands, this being ac-, complished by an auxiliary pedal device.

The invention consists in certain novel combinations and arrangements of parts as will be hereinafter more fully pointed out and claimed.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention and a slight modification thereof, constructed according to the best mode I have so far devised for the application of the principles of my invention, but it will be understood that changes involving shapes and sizes of parts and colorable alterations are contemplated as within the scope of my claims.

Figure 1 is a side elevation of the device embodying my invention, the separated parts of the device being closed up for-convenience of illustration. Fig. 2 is a top plan view of Fig. 1. Fig. 3 is a front elevation of the device of Fig. 1, showing the pedal board and the music rack and leaf turner. Fig. 4 illustrates the three spring operated sprocket wheels, one for each leaf turner when three are used. Fig. 5 is a side view of the spring wheel at the left in Fig. 4,

showing the spring in its casing and attached to the wheel shaft. Fi 6 is a sectional view of the device of F 1g. 5 on line 6 6. Fig. 7 is a sectional detail view of the bearing head of Fig. 3. Fig. 8 illustrates the three locking latches for their respective pedals, and the return pedal slide rod co-acting therewith. Fig, 9 shows a modified form of head for the leaf turner. Fig. 10 is a sectional view of the head of Fig. 9.

In the preferred embodiment of my invention as illustrated in the drawings I employ a music rack or board 1 of convenient and proper size to be located in suitable position over the key board of the instrument, and suspended, vertically, by means of its bracket rod 2 which is supported in the bushing or head 3 of the swivel plate 4..

The board or rack 1 is equipped with the usual bottom ledge 5 and the pairs of spring retaining clamps or

clips

6 and 7 for holding the front and back pages of the music to the rack 1.

The rack may be supported from a suit able portion of the piano, or if used as a portion of a music stand, it may be supported from a wall. In any event the swivel plate 4 is adjustably secured to the adjustable slide plate or extension 8 through the pivot bolt 9 by which the swivel plate and slide plate are held, and the circular slot 10 in the plate 4 and set screw 11 which passes through the slot and is threaded in the end of the slide plate 8. By this connection it will be seen that the music rack may be adjusted on the pivot point 9 in order to vary the inclination of the music rack with rela tion to the vertical.

The adjustable slide or extension plate 8 is perforated to accommodate two bolts or screws 12. 12 which are utilized to secure the extension plate 8 in desired relation with the complementary plate 13 which is also slotted as at 13 to accommodate the

screws

12, 12 and overlaps the adjoining end of the plate 8. This arrangement of parts permits of an adjustment of the music rack toward or away from its supporting wall or other object, and enables the artist or musician to adjust the rack to his wishes.

A further adjustment of the device is accomplished through the connection between the arm 13 and the bracket 14 by means of which the music rack is supported from a stationary member as 15 by screws 16. The bracket 14 is fashioned with a swivel head 17 slotted 18 and pivotally connected with the arm 13 by the bolt 19. Thus this swivel connection may co-act with the swivel connection at the free end of the extensible arms 18 and 8, and when in adjusted position the

parts

13 and 17 may be secured together by the screw in the drawings T have illustrated the device as equipped with three leaf turners A, B, C, and it will be seen that these comprise angular arms each provided with the

usual spring clamps

21, 22, provided with a release lever 22 to hold the leaf and insure its quick and proper movement when the leaf is turned. The leaf-turners are each fashioned with a shank or arm 23, 24-, 25 respectively and these respective arms are fixed to bushings 26, 27, 28 of their

sprocket wheels

29, 30, 31. These bushings and sprocket wheels are rotatable on the bracket rod or shaft 2 which is threaded at 2 for the clamp nuts for holding the revoluble members on the shaft 2. Each of these sprocket wheels is revolved by a section of chain as 33, 8%, passed over the respective wheels and each chain has attached at its ends a cord or cable as 36, 37, 38, passing over guide pulleys 39 and tO, down to the pedal mechanism that is located in convenient position to be actuated by the foot of the musician.

Each pedal device includes a sprocket wheel as it, 4-2, 4:3 and a section of chain as 44 is passed over each sprocket and connected to the ends of its individual cord or cable.

The sprockets ll, 42, i3 are spring wound 2'. 6. each is equipped with a spring as L5, fastened. at one end in its casing i6 and at its other end to the shaft t? of the sprocket wheels. Each of these shafts has a pedal as as, L9, 50, formed each with a hook 51, for engaging the shaft and said pedals coact with a pivoted latch 53, 5a and 55, which have the cam face 52 and are pivoted at 56 on the board 57, the springs 56 being provided for retaining the latches in normal position. This cover board 57 is slotted so that the hooked ends of the pedals may protrude from the interior, and it will be apparent "hat by depressing the pedal 48 for instance by foot power, the cam face 52 will be forced aside to allow the pedal to pass below the straight underside of the latch 53, when the spring 56 will return the latch and thus retain the pedal in downward or depressed position, this depressing of the pedal revolves the sprocket wheel ll, winding or tightening the spring do, which re turns the parts to normal position as is hereinafter set forth, and through the chain and cord connections the leaf turner is folded or swung over to turn the leaf of music. The three pedals are operated successively and their individual actions are similar A fourth pedal is employed to return the latches to normal position. This pedal is pivoted on the cover board 57 at 59 and connected to a slide bar 60 at 61; The slide bar is movable in bearings 62 and is formed with series of three lugs 63 adapted to impinge against the lower end of the latches. When the pedal 58 is pressed down, the movement of the slide bar 60 to the right, see Fig. 8, moves all of the latches on their pivots 56, releasing the pedals 4:8, 49 and and allowing the springs 45 to unwind, revolving the sprocket wheels ll, 42 and backward, and through the chain and cord connections return the leaf turners to normal position, and when pressure is removed from the pedal the spring restores the latches to their normal position. Each latch is provided with an individual pin as 64; by means of which it may be swung on its pivot and returned to normal position.

In the modified forms of the invention in Figs. 9 and 10 the arms 25 24B 23 are ar ranged below the head 3 instead of above the head, to make more compact arrangement of parts which is sometimes desirable.
