(CI. 45-82) My invention relates to music racks and more Figure 12 is a sectional view taken on the line particularly to auxiliary music racks for pianos. The music rests provided on the music desks 5 - In general my invention contemplates the pro vision of a supporting means adapted to clamp of pianos are primarily designed for adults. Children and near sighted persons have difficulty in using the music rests provided. There is a tendency to lean ‘forward, thus causing a particu upon the music rack of the piano and at once acts I larly unfavorable condition. Not only is the posi tion at the piano improper but in leaning forward Means are provided for adjusting the auxiliary and looking upwardly an undue amount of energy and also as to angle. is necessary, inducing fatigue and early robbing the child of its ability to concentrate at the music lesson._ The correct distance of music from the player’s eyesshould be sixteen inches. 16 One object of my invention is to provide a music rack which can be adapted to the music rest of the music desk on all pianos, including both the grand piano type and the upright piano type. Another object of my invention is to provide a 20 music rest which is light in‘ weight, can be easily adjusted and will not scratch or injure the piano. ' ther and further objects of my invention will 25 l2—-l2 of Figure 11. appear from the following description. In the accompanying drawings, which form part of the instant specification and are to be read in conjunction therewith and in which like reference numerals are used to indicate like parts in the various views. 30 Figure 1 is a fragmentary elevation of a grand piano showing my music rack in place. Figure 2 is a sectional elevation of the music rack shown in Figure 1. Figure 3 is a sectional view of a portion of my 35 music rack showing the music rest in one ad justed position. ' Figure 4 is a sectional view similar to that of Figure 3 showing the music rest in another ad justed position. Figure 5 is a perspective view of a portion of my assembly. Figure 6 is a perspective view of a detail. Figure '7 is an enlarged sectional view of a de tail. Figure 8 is an enlarged fragmentary elevation of a detail. Figure 9 is an elevation of a portion of an up right piano showing my music rack attached 50 thereto. Figure 10 is a side view partly in section of the arrangement shown in Figure 9. Figure 11 is an elevation on an enlarged scale of a portion of the assembly used on upright 55 pianos. as a support for the auxiliary music rack proper and as a bracing means for the piano music rack. music rack as to height, distance from the user More particularly ‘referring now to the draw 10 ings, the music desk of a grand piano usually comprises a member I pivoted at 2 so that it is adapted to assume the position shown in Figure 2 when erected. When not in use the music rest I is adapted to be pivoted around the hinge 2 so that the upper end will move to the left as viewed in Figure 2, that is toward the front of the piano. The supporting member 3 is then adapted to slide backwardly to closed position. There is 20 also provided a stringer 4 against which the lower edge of the music rests. The music racks l on various pianos are of different heights. The height of the music rack above the keys on dif ferent pianos is different and the support upon 25 which the music rack I is pivoted likewise is dif ferently positioned and has different amplitudes of motion. Furthermore, the angle which the music rest I assumes when in erected position is different on different pianos. 80 For grand pianos my music rack comprises a board 5 to which is hingedly connected a member 6. Member 6 is provided with a groove 1 in which the tongue 8 of clamp member 9 is adapted to ride. An auxiliary clamping member l0 may be provided. The pivotal connection between mem bers 5 and 6 may be by means of ?exible mate rial H glued or otherwise secured to both mem bers 5 and 6. The back of members 5 and 6 may be covered by felt l2 to prevent scratching the music rest of the piano. In use the clamping assembly is clamped over the top of the music rest of the piano by means of a clamping bolt l3 with the lower end of board 5 positioned against the stringer 4 as can readily be seen by reference to 45 Figure 2. In this position the board 5 will act as a brace preventing the music rest of the piano from pivoting around its hinge 2. The board 5 also acts as a support upon which the auxiliary music rack is adjustably mounted as will herein 50 after more fully be pointed out. Referring now to Figure 6 there is shown a bracket. One end M of the bracket I5 is adapt ed to embrace the board 5 as can readily be seen by reference to Figures 3 and 4. To the arms I6 55 2,133,368 2 of the bracket I secure the auxiliary music rest proper IT, by means of a clamp bolt l8. clamped between the arm I6 and the music rest II are a pair of wedges l9 and 20 through which the angle of clamping can be readily adjusted. It will be observed that if both narrow portions of the wedges are downwardly the angle between the brackets l6 and the plane of the music rest I? will be less than 90°, as shown in full lines in 10 Figure 2. By positioning one thin end upwardly and one thin end downwardly the angle can be made to be 90°, as shown in dotted lines in Fig ure 2 and in full lines in Figure 7. By placing both butt ends of the wedges together and posi 15 tioning them downwardly, the angle between the bracket l6 and the plane of the music rest ll can be made greater than 90°. It will be observed by intermediate positioning of the wedges, any de sired angle between the limits of the wedges can 20 be achieved. Likewise, different angles can be obtained by using only one of the two wedges of a clamping bolt 3!. In this manner various heights can be readily accommodated. The up per end of the member 26 is clamped to the up per end of the music rest 24 by means of the clamp 28. The music rest is moved to open po sition, as shown in Figure 10, and the lower end of the board 30 is placed against the stringer 32 of the piano. The clamping bolt 3! is then clamped to the music rack ll and its bracket with embracing end I4 is positioned upon the 10 board 38 precisely in the same manner as upon board 5; board 30 and board 5 being made of the same weight and thickness. It will be observed that I have“ accomplished the objects of my invention. I have provided an 15 adjustable auxiliary music rack which may be used upon all makes of grand and upright pianos. The construction is such that it will not scratch the piano, is light in weight, is easily adjusted and will provide a music rack which will enable 20 children to have the music properly positioned, or by using wedges having diiferent angles. In thus avoiding nervous strain and fatigue occa this manner a simple adjustment to obtain the desired angle for the music rest H is achieved. 25 The bracket 55 is made of malleable metal and the arm iii of the bracket is secured to the music sub~combinations are of utility and may bev em rest ll through slots 2 I. ‘ Referring now to Figure 3 it will be noted that the distance between end M of the bracket and the music rest I? is greater than this distance in Figure 4, thus providing an adjustment of dis tance of the music rest from the board 5 to en able the music rest to be used on pianos having sioned by improperly positioned music. It will be understood that certain features and 25 ployed without reference to other features and sub-combinations. This is contemplated by and is within the scope of my claims. It is further obvious that various changes may be made in de tails within the scope of my claims without de 30 parting from the spirit of my invention. It is, therefore, to be understood that my invention is not to be limited to the speci?c details shown and described. Having thus described my invention, what I ‘claim is: 1.
