UNITED STATES ANDREW H. MILLS, OF WARSAW, INDIANA.

MUSIC-LEAF TURNER.

Application filed August 3, 1921.

To all whom it may concern:

Be it known that I, ANDREW H. MILLS, a citizen of the United States, residing at Warsaw, in the county of Kosciusko and State of Indiana, have invented certain new and useful Improvements in a Music-Leaf Turner, of which the following is a specification.

This invention relates to music leaf turners, and has for one of its objects to improve the construction and increase the efficiency and utility of devices of this character.

Another object of the invention is to provide a device of this character adapted to be attached to a standard for use by a musician playing an individual instrument or as a member of a band, or arranged for use on a piano, as may be preferred, without material structural change in the device.

Another object of the invention is to provide a simply constructed attachment whereby the improved device may be adapted for a large number of sheets of music, such as employed by musicians in bands and like purposes.

With these and other ebjocts in view the invention consists in certain novel features of construction as hereinafter shown and de scribed and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention.

Figure 12 is a plan view of the music sheet holding frames Figure 13 is a side elevation of the parts shown in Figure 12.

Figure id is a perspective View of a portion on one of the music sheetholding frames.

Figure 15 is an enlarged perspective View of the upper hinge members of the music sheet holding frames.

Figure 16 represents the blanks from which the lower hinge members of the music sheet holding frames are constructed.

The improved device may be arranged for use in connection with an ordinary foldable music stand operative by a foot lever or pedal, or mounted on the music rack of a piano or the like and operative either by the hand or foot.

The improved device comprises a base or platform 10, having a plurality of concentrically arranged segmental guideways 11, which have a common center in a post or standard 12, rising from the base 10. The guideways are slightly undercut or dovetailed as shown.

For the purpose of illustration the base 10 is mounted upon a support comprising a standard 13 having a sleeve lel at the lower end, the latter having ears 15to swingingly receiv foldable legs 16.

By this means the improved device may be moved from place to place in the same manner as an ordinary music stand. A frame for supporting the sheets of music each represented as a whole at 17, is provided for each guide channel 11. Each frame 17 is provided with leaf holding clips 18 at its upper outer corner and another leaf holding clip indicated at 18 at the inner upper corner. Each of the frame members 17 is also provided with a stud or projection 19 at its lower edge.

Any required number of the guide channels 11 and corresponding frames 1'? may be employed, but for the purpose of illustration three of the guide channels and three of the frames are shown.

Mounted to swing upon the standard 12 are superposed plates 20, 21, and 22, one for each of the frames 17, and upon which their lower inner corners rest, the plates having upstanding cars 23, 24, and 25. The ears 23 receive the lower inner corner of the right hand member 17 the cars 24 receive the lower inner corner of the left hand member 17, while the ears 25 receive the lower inner corner of the central member 17 as shown. Mounted to swing upon the post 12 near its upper end is a plate 26, while a similar plate 27 is also mounted to swing upon the same post, while athird plate 28 is likewise mount ed to swing upon the same post, the inner ends of the plates being provided with hinge members to rotatably engage with the post and to interengage as shown. The left member 17 is attached to the plate 26 while the right hand member 17 is attached to the plate 27 and the central member 17 is attached to the plate 28. By this means the plates 20, 21 and 22 coact with the plates 26, 27, and 28 to effectually support the holding member 17, for oscillation upon the post, as will be obvious.

The holding members 17 are preferably constructed of plates of sheet metal as light as possible consistent with the strains to which they will be subjected, the ends of the members 17 being folded upon each other and the upper and lower strips or members of the frame 17 are soldered or otherwise secured to the ends of the folded members shown. By this means a very simply constructed and rigid frame is produced, the parts being of relatively thin strips of sheet metal, thus reducing the expense and weight.

Mounted for slidable movement in the channel 11 are block members 29 each block having a standard 30 rising therefrom and each standard having a laterally projected terminal 31, the latter adapted to consecutively engage the downwardly directed projection member 19 of the member 17, as the members 29 are moved in the grooves or channels 11, as hereafter shown.

The members 29 are arranged in the respective channels 11 slightly in advance of each other, or arranged in skip-like order, so that when the members are disposed in one position the projecting portions 31 will engage the projections 19 simultaneously, or initially in contact with their respective pro- 'jections.

Pivoted in the bottom of the channel is a stop pawl 32, spring supported'and adapted to be projected by their springs into the paths of the blocks 29, and thus held initially in their withdrawn position, or at one end of the channel 11, as illustrated in Figures 7 and 9.

Attached to each of the pawls 32 is a pull wire or cord 33 bearing over suitable guide pulleys 34 and conducted downwardly alongside of the standard 13.

Rigidly connected to the standard 13 adj acent to the collar 14 is a standard including a body portion 35 and ears 35' at one end of the latter adapted to be extended around the standard 13 and secured thereto in any suitable manner.

At its lower end the member is provided with perforated ears 36 to receive one end of a pedal member 37. The pedal is formed in three portions, or as many portions as there are channels 11 and the wire member 33, or as many pedals as there are frame members 17 The members 37 are connected respectively to the pull wires 83, so that each pedal will operate one of the wires and release one of the pawl members 32.

Mounted for rotation on the member 10 at the ends of each of the channels 11 at the left is a winding drum 38 each having internal springs 38 to hold them yieldably in one position or wound up. Connected to each of these drums 38 is a pull cord or wire portion 39 leading through the channels 11 and attached respectively to the block member 29. Mounted within the channels 11 at suitable intervals are guide pulleys 40 over which the cords 39 are directed so that the pull of the drum 38 will be direct at all times upon the block members 29. By this arran ement it will be obvious that by moving t e block members 29 against the resistance of the springs 38 until they are engaged by the pawls 32, the blocks will be held initially in withdrawn position or at the end of the channel opposite to the winding drum 38. In disposing the device in position for use the sheets of 1111181 are arranged upon the members 17, one sheet being attached at its upper edge to one set of clips the clips 18, and the united member 17 rotated until they are all in spaced relation and in parallel relation at the initial end or turned to the right as illustrated in Figures 1, '7, and 12.

This will bring the projecting portions 31. respectively in the rear of the downwardly projecting stops 19, as will be obvious.

The pedal members 36 are so arranged that the foot of the operator can bear upon any one of the members 36 independently of the others. And in operating the improved device after the first sheet of music has been played through, the operator places his foot upon the left pedal 36 which will release the left pawl 32 and permit the spring 39 of the drum 38 at the inner side to draw the block member 3 around in the groove 1.1 carrying the member 17 with which it is associated and the sheet of music attached thereto, and reversing it into position. After the next page of music has been played the operator compresses the next pedal and thus draws the next sheet of music around and disposes it at the opposite side.

After the second sheet has been played the third pedal is actuated and the third sheet of music reversed in position in the same manner.

The improved apparatus is simple in construction and easy to manufacture and adapted without material structural change to any required number of sheets of music, as before stated.

Having thus described the invention what is claimed as new is 1. In a music leaf turner, a support having a segmental guideway, a follower device movable in said guideway and maintained in position by the walls of the same, a leaf holder device movable over said support and having a portion extending into the path of said follower device, means for forcibly moving said follower device in said guideway, a stop pawl holding said follower device in withdrawn position against the action of the moving force, and means under the control of the player for releasing said stop pawl.
