ARTHUR WALTER MILLER, OF YVILD ROSE, SASKATCHEWAN, CANADA.

MUSIC-LEAF TURNER.

Application filed July 18, 1911.

To all whom it may concern:

Be it known that I, ARTHUR WV. MILLER, a subject of the King of Great Britain, residing at lVild Rose, in the Province of Saskatchewan and Dominion of Canada, have invented new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

This invention relates to music leaf turners and the object of the invention is the provision of a device of this character wherein the leaves of sheet or book music may be readily and conveniently turned so as to avoid delay in turning the leaves by hand.

A further object of the invention is the provision of means, in a device of this character, for holding the leaf to be turned and also the leaves preceding the same in such instances where there are several intervening leaves between the first leaf and the second leaf to be turned.

A still further object of the invention is the provision of novel means for adjusting the size of the rack and the length of the turning arms so as to accommodate the device for different sizes of sheet and book music.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawings, which form a part of this appliation, and in which Figure 1 is a front elevation. Fig. 2 is a side elevation. Fig. 3 is a horizontal section taken on the line of Fig. 1. Fig. 4 is a detail vertical section taken on the line et4 of Fig. 1. Fig. 5 is a detail horizontal section taken on the line of Fig. 1. Fig. 6 is a detail perspective view of the mounting clips. Fig. 7 is a detail section through the frame on the line 7-7 of Fig. 1 showing the application of the clip thereto. Fig. 8 is a perspective view of the sheet clamp removed fro-m the frame.

Referring more particularly to the drawings, the frame is constructed of side members 1 and 2, a top member 3 and a bridge piece 4. Immediately below the bridge piece the legs or side members 1 and 2 are connected by the book supporting bracket 5 and extendingtherefrom, over the bridge piece 4 to the top member 3 in the center of the frame, is a center piece 6. This center piece 6 rests upon the bracket 5 at 7 Extending at right angles from the ex- Specification of Letters Patent.

tension 8 and arranged in separated relation are bracket pieces 9 in which are secured the shafts 10 and 11, the former being directly in line with the center of the frame and having loosely mounted thereon the independent hubs 12 and 13. These hubs are normally held in contact with each other by operating springs 14 and 15 which have one end connected to the brackets and their opposite ends connected to the respective hubs so that, when the hubs are turned upon the shaft, the springs will be placed under tension. Each hub is provided with a suitable notch 16 which is adapted to be engaged by the pawls 17 and 18 journaled upon the shaft 11. These pawls are normally held in engagement with the hubs by means of springs 19 which surround the shaft 11 and are connected to the brackets at one end and to the pawls at the other. At the opposite side of the shaft the pawls have extensions in the form of levers 20 and 21 upon the outer ends of which are secured suitable operating buttons 22 which when pressed, will release the pawls from the hubs.

Secured into the hubs 12 and 13, adjacent the notches, are substantially L-shaped securing members to which. are suitably secured the hollow turning arms 2% and 25. These arms have suitable reinforcements 26 upon their outer ends into which are threaded the set screws 27 adapted to clamp the extensions 28 and 29 of said arms. These extensions are substantially U-shaped in outline, one leg being considerably longer than the other so as to slide within the arms 2st and 25. Both the extensions and the arms and are preferably squared so as to prevent relative turning. The upper end of each extension 28 and 29 upon the opposite leg from that secured in the arms 24: and 25 has secured thereto clamps 30 and 31 which are adapted to receive the leaves of the music. The clamp 31 also carries a spring 32 which is adapted to engage the leaves of the book, as will be hereinafter described.

Slidably mounted in grooves 83 formed in the upper and lower edges of the cross piece are rods 34 which have connected to their outer ends the supporting plates or extensions 35. These rods are adapted to be normally telescoped within the grooves so that the plates or extensions 35 lie along side of the legs or side members 1 and 2. When extended the frame is adapted to receive large sheet music, the extensions 28 and 29 being adjusted in the arms 2t and so as to properly connect with the edges of the sheets.

The center member 6 is rabbeted out upon its rear side and the flanges 36 formed are provided with grooves 37 in which are slidably mounted the legs 38 of the U-shaped extensions 39. This extension is adapted to be used in connection with supporting clips 40 for mounting the frame upon the music rack of a piano or organ. They consist essentially in a single piece of material having one end bent back upon itself and slot ted, as at 41, to receive the head (1'2 of a rivet which passes through the legs of the frame. Suitable ears 43 are bent out fro-m the sides of the clip so as to straddle the leg and prevent lateral movement of the clip. The rivets s2 are headed upon the front side of the legs so as to receive the spring arms 4A which are adapted to clamp the sheet of music to the frame which lies adjacent the last sheet to be turned or preceding the first sheet.

In order to hold the sheet music down upon the center piece the clamping arm 45 is provided having a right angularly offset lower end to which is bent back upon itself in the form of a triangle so as to clamp'over the member 5, as shown, the arm lying against the center piece.

In the operation of the device a sheet of music is placed upon the frame beneath the clamping bar a?) which lies in the center of the sheet and the arm 25 bent over to the right of the frame against the tension of the spring 15. The pawl 18 engages the notch in the hub and holds the arm in position at the right hand side of the frame where the last page to be turned is clamped in between the jaws of the clamp 31. The arm 24; is then bent over in a similar manner against the tension of the spring l t, the pawl 17 properly engaging the notch of the hub and holding it in such position where the clamp is engaged with the first page to be turned. By pressing the button 2st of the pawl 17 the hub 12 is released and the arm 2% thrown over the left of the frame, carrying with it the attached page. The pawl 18 is then operated to release the hub 13, so that the arm 25 may be similarly thrown by the spring 15. While loosening the set screws 27 the extensions 28 and 29 may be adjusted outwardly so as to accommodate the device to any size of sheet music. The extensions are drawn out to accom modate different sized sheet music. The frame normally has its legs resting upon the rack of the piano or organ but when the music is too heavy with the frame in this position it is dropped down so that the clips rest upon the rack. In this position the U-shaped extension 39 is pulled out so as to engage beneath the top of the pinion or organ and hold the frame firmly in position.

Having thus described the invention, what I claim as new is 1. A music leaf turner comprising a frame, a bracket arranged centrally of and depending from said frame, a pair of vertically disposed parallel shafts mounted in said bracket, a plurality of independent notched members loosely mounted on one of said shafts intermediate its ends, sheet turner means carried by said notched members, operating springs encircling said shaft above and below said notched members and adapted to normally hold said members in engagement with each other, said springs having one terminal secured to the bracket and the other terminal connected to the respective hubs and adapted to be placed under tension on rotation of said hubs, pawls loosely mounted on the other of said shafts and adapted to hold said notched members against rotation, springs encircling said shaft above and below said pawls and adapted to retain said pawls in operative position with relation to said notched members, and operating arms carried by said pawls, substantially as and for the purpose set forth.

2. A music leaf turner, comprising a frame having an extension depending centrally therefrom, spaced bracket members extending at right angles from said exten sion and forwardly of said frame, a pair of vertically disposed shafts mounted in said bracket members and arranged in parallelism with each other, one of said shafts being disposed in line with the center of said frame, a plurality of independent notched members loosely mounted centrally on said shaft, sheet turning means carried by said notched members, operating springs encircling said shaft above and below said members and adapted to normally hold said members in engagement with each other, pawls loosely mounted centrally on the other of said shafts, springs encircling said shaft above and below said pawls and having one end connected thereto and operating to hold said pawls in operative engagement with said notched members, and operating arms carried by said pawls for the purpose specified.

In testimony whereof I atlix my signature in presence of two witnesses.
