EDDIE GOODELL ABBEY, OF MONETT, MISSOURI.

MUSIC-LEAF TURNER.

Application filed June 3, 1910.

To all whom it may concern:

Be it known that I, EDDIE G. ABBEY, a citizen of the United States, residing at Monett, in the county of Barry and State of Missouri, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an improvement in music leaf turners and one of the objects of the present invention is the provision of a simple and eflicient device of this character which is housed within a casing adapted to be supported upon a music rack after the manner of the usual music book and which, when not in use may be used as a receptacle for the music and may be readily trasnported from place to place.

A further object of the present invention is the provision in a device of this character, of improved means for turning the several leaves as they are played so that the turning of the leaves is effected by the natural movement of the hand of the person while playing and there is thus no interference with the proper execution of the music being played.

A further object of the present invention is the provision in a device of this character, of means whereby all of the leaves which have been turned may be simultaneously restored. to their initial position.

Other objects of the invention will be apparent from the detailed description hereinafter when read in connection with the accompanying drawings wherein a convenient embodiment of the invention is illustrated and wherein like numerals of reference refer to similar parts.

In the drawings: Figure 1 is a perspective view of the device in its closed position, Fig. 2 is a plan view of the device in its open position, Fig. 3 is a cross section on line 3 3 of Fig. 2, and Figs. 4, 5 and 6 are detail views.

Referring now more particularly to the drawings the body portion or case of the device comprises two flanged sections A, A which are hinged together at their inner edges and are adapted when folded to constitute a receptacle for holding sheet music and for carrying the same from place to place. The sections of the case are preferably so formed as to simulate the appearance of a book when folded and any suitable Specification of Letters Patent.

means is provided for locking the sections together when in their folded position.

B designates a shaft which extends for substantially the full length of the case and is positioned in substantial alinement with the axis of the hinges connecting the sec tions of the case. The upper end of the shaft B is journaled in a bracket 6 which is secured to a block B secured in the upper portion of the section A of the case, while the lower end of said shaft is journaled in a bearing Z) which is secured to the inner side of the lower end flange of the section A of the case. The lower end of the shaft B projects without the lower end of the case and terminates in a squared portion upon which is removably secured in any suitable manner, an actuating key B by means of which the shaft may be shifted in its bearings for a purpose to be hereinafter more particularly set forth. For convenience in shifting the shaft B the actuating key B is preferably secured thereto at an angle of +15 to the plane of the sections of the case when the same are in their open position.

Loosely mounted upon the shaft .B are a plurality of music carrying arms C, which may be com'eniently formed of sheet metal. Any number of music carrying arms C may be employed, four of such arms being shown in the embodiment of the invention illus trated in the accompanying drawings. Each of the music carrying arms C comprises a longitudinally disposed portion 0 which extends for substantially the full length of the case and from which depend ears 0 which loosely embrace the shaft B, and a portion 0 which projects laterally from the upper end of said longitudinally extending portion, said laterally projecting portion being slightly greater in length than the width of one of the sections of the case.

The several music carrying arms C are adapted when occupying either the section A or the section A of the case, to lie one upon the other and the laterally projecting portions 0 thereof are covered, either partially or wholly, with some sound deadening material 0 such as felt or like material. The sound deadening material on the laterally projecting portions of the music carrying arms not only serves to prevent any noise which might be caused by the impact of the music-carrying arms when shifted during the operation of the device, but the covering of the arms with such material also serves to space the outer end of the arms a slight distance apart when they are resting one upon the other.

The music carrying arms are normally held in the section A of the case by springs 0, there being one such spring provided for each of the music carrying arms. The springs c are conveniently in the form of flat leaf springs and the inner ends thereof are superposed and are secured to the block B in the section A of the case, heretofore referred to, by means of a metal plate which overlies the superposed ends of the spring and is secured to said block by screws or other suitable means. The free end of each of the springs 0* is secured to one of the music carrying arms C and the form of the springs is such that when they are so secured they will have a tendency to hold the music carrying arms in the section A of the case, one upon the other. lVhen the arms are in this position in the section A of the case it will be seen that any music which is placed in the section A beneath said arms will be held by the tension of said springs against displacement. The free ends of the springs 0 may be secured to the music carrying arms in any suitable manner and in the form of the invention illustrated each of the laterally projecting portions 0 of the music carrying arms is provided with a portion 0 extending upwardly therefrom which is folded about the ends of one of the springs. Obviously, however, the free ends of the springs might be attached to the laterally projecting p0rtions of the music carrying arms in any other desired manner.

Each of the laterally projecting portions 0 of the music carrying arms C is provided with means for detachably securing thereto a sheet of music and in the form of the invention illustrated in the drawings each of said laterally projecting portions has secured to its upper face adjacent the ends thereof sheet metal hooks c which hooks are engaged by an elastic band 0 under which the sheet of music is slipped when it is desired to secure the same to the music carrying arm. In lieu of the band thus described sheet metal clips may be secured to the laterally projecting portions of the music carrying arms for the purpose of clamping the sheets of music thereto.

The springs 0 as heretofore stated, serve to normally hold all of the music carrying arms C in the section A of the case and the shaft B is operatively connected to the lowermost one of said arms when they are so positioned, so that by shifting said shaft through the instrumentality of the key B heretofore described, all of the arms may be turned and moved to a position in the section A of the case. In the form of the invention illustrated the means utilized for this purpose comprises an arm Z2 which projects laterally from the upper end of the shaft B and the outer end of which is secured in any suitable manner to the music carrying arm C which is lowermost when such arms occupy their normal position in the section A of the case. hen the shaft 13 is turned to shift the music carrying arms C to the section A of the case, means are provided to lock the arms in said section and to release the same one by one, thereby permitting the springs to shift the arms back into the section A of the case and thus effect the turning of the sheets of music carried thereby. This is accomplished, in the embodiment of the invention illustrated in the drawings, by means of a rod D, which is positioned in a groove or channel formed in the upper surface of the side flange of the section A of the case and which is provided adjacent its upper end with a downwardly bent U-shaped portion (Z. The upper portion of the side flange of the section A of the vase is provided with a pocket in the inner surface thereof over whiclr'is removably secured a plate F which is provided with integral flanges projecting from one side thereof in which are slidably mounted the portions of the rod D at each end of the U-shaped portion (Z thereof. The space between the flanges f of the plate F is such that when the rod 1) is moved downwardly until the U-shaped portion (Z thereof contacts with one of said flanges, the upper portion of said rod will have been disengaged from the other of said flanges, thus permitting the rod to be removed withoutdisengaging the bearing plate. The bearing plate F is provided with a cut-away portion f therein into which the outer end of the music carrying arms C are moved when such arms are shifted from the section A of the case to the section A of the case. Rigidly secured to the side arm of the U-shaped portion (Z of the rod D, nearest to the lower portion of the case is a hook member (1 having an upwardly projecting nose. Pivotally secured to the side arm of the U-shaped portion (Z of the rod D, which is nearest to the top of the case is a hook member (Z having a nose turned toward the nose of the hook member (l but positioned in a higher plane. A spring (1 which is secured to the bearing plate F engages the rear portion of the hook member (Z and such hook member is provided on its rear edge with a portion (Z' which is adapted to engage the arm of the U-shaped portion (Z of the rod D and thus limit the movement of the hook portion on its pivot. The spring (Z serves to normally hold the hook portion (Z in a position at right angles to the rod D. lVith the hook portion (Z thus held against movement on its pivot, the spring also serves to normally shift the rod D in its bearing, means being provided, however,

as will be hereinafter more particularly set forth, for preventing the spring from shifting the rod a sufficient extent to disengage the upper end thereof from its bearing wit-l1 the flange projecting from the plate F. The nose of the hook member d is beveled and when the music carrying arms are moved to their position in the section A of the case they will engage the beveled face of the nose of the hook member d and as such member is pivoted it will be forced upward on its pivot, allowing the arms to pass into position below the nose, the spring 6Z3 returning the hook member (Z to its normal position with the nose thereof overlying the topmost one of the music carrying arms and thereby looking all of such arms in the section A of the case. The hook members (Z and (Z are so spaced apart that when the nose of the hook member (Z is in engagement with the uppermost one of the music carrying arms C, the nose of the member (Z is out of engagement with the arm C and the members are normally held in this position by the spring (Z G designates an actuating member for releasing the music carrying arms from the sections A of the case and permitting the same to be shifted to the section A thereof by their respective springs. In the embodiment of the invention illustrated such actuating member comprises a wire or rod, which is pivotally connected at its inner end to the lower flange of the section A of the case, adjacent its connection with the section A, and which extends downwardly and outwardly to the outer edge of the section A of the case and terminates in an upwardly bent portion 9, the upper end of which is bent inwardly as at g and is pivotally connected by means of a removable pin 9 with the lower end of the rod D which projects beyond the lower flange of the section A of the case. The laterally projecting portion 9 of the actuating member G passes through a slotted guide plate 9 which is secured to the exterior of the lower edge of the section A of the case and which serves to limit the downward movement of the rod D due to the tension of the spring (Z thereon. The slot in the plate 9 is of such a length that the rod D cannot be moved downwardly a sufficient distance by the spring 623 to disengage the upper end thereof from its bearing in the flange proj ecting from the plate F. If for any reason, however, it is desired to remove the rod D and its attached parts, the lower end of the rod D can be disconnected from the actuating member G so that the rod can be shifted downwardly a sufficient extent to withdraw the upper end thereof from engagement with the flange projecting from the plate F after which the rod can be readily disengaged.

In using the device, the music carrying arms C are all moved into the section A of the case and engaged under the nose of the hook member d After the music on the first sheet has been played-and the player desires to turn such sheet, the hand is elevated until the back thereof engages the actuating member G and moves the same upwardly on its pivot. Such movement shifts the rod D upwardly and moves the hook member (Z from out of engagement with the top-most arm C, thus permitting its spring to shift such arm to the section A of the case. During the movement of the rod D which effects the disengagement of the hook member (Z from the top-most arm C, the hook member (5 is moved so as to overlie the arm C immediately below the top-most arm and thus prevent the release of but one of such arms at a time. As soon as the pressure on the actuating member G is released, the spring 6Z3 will restore the parts to their normal position.

Inasmuch as the actuating member is of a width substantially equal to the width of one of the sections of the case, it will be apparent that the player may by merely raising the hand to a slight degree more than it is raised in playing the music, engage such member at any point and effect the turning of the leaf, so that since no special movement of the hand is required to effectthe turning of the leaf there is no interference with the proper execution of the music being played. l urthermore, since the lower edge of the actuating member slopes downwardly, it will be seen that the necessary movement can be imparted to the rod D to efiect the turning of the leaf by a lateral movement of the hand.

Vhile a convenient embodiment of the invention is illustrated in the accompanying drawing it will be understood that many changes may be made to the aforementioned structure therein shown without departing from the spirit and scope of the invention as defined in the appended claims.
