WILLIAM C. BOSENBURY, OF RICHMOND, INDIANA, ASSIGNOR TO STARR PIANO COMPANY, OF RICHMOND, INDIANA.
MECHANISM FOR ADJUSTING MUSlC-DESKS ON GRAND PIANOS.
SPECIFICATION forming part of Letters Patent N 0. 687,193, dated November 26, 1901.
Application filed April 6, 1901. Serial No. 54,708. (No model.)
To aZZ whom it may concern.-
Be it known that 1, WILLIAM C. BOSEN- BURY, a citizen of the United States, residing at Richmond, in the county of \Vayne and State of Indiana, have invented new and useful Improvements in Mechanism for Adjusting Music-Desks on Grand Pianos, of which the following is a specification.
The object of my present invention is to provide a music-desk especially adapted to be used in connection with grand pianos.
Anotherobject is to provide improvements for adjusting music-desks 011 grand pianos simple in construction, attractive in appearance, and efficient in operation.
I attain the above and other minor objects, which will appear from the subjoined description and from the mechanism illustrated in the accompanying drawings,forminga part of this specification, in which Figure 1 is a cross-section of a music-desk attached to a grand piano by means of and showing my improvements, taken on the line X X of Fig. 3, showing the desk closed. Fig. 2 is a cross-section of a'music-desk attached to a grand piano by means of and showing my improvements, taken on the line X X of Fig. 3, showing the desk opened. Fig. 3 is a top or plan view of a portion of a music-desk and a piano,showing my improvements. Fig. 4. is a detail sectional View showing a portion of my improvements, taken on the line Y Y of Figs. 1 and 3. Fig. 5 is a detail view showing a portion of the music-desk 1 on the opposite side than that shown in Fig. 3.
Similar figures of reference denote and refer to like parts throughout all the several views.
To accomplish the foregoing objects and other objects not specifically n1entioned,lpro- Vide the parts and the arrangement thereof as shown in the accompanying drawings and referred to by the following numerals.
1 represents the middle member of my improved double hinge, taken in connection with the two end members 2 and 3, each being hinged to the member 1, thus forming a hinge of novel construction designed by me for purpose for which it is herein shown and described. The outer members are provided with screw-holes for the purpose of attaching to the music-desk 7 by screws and provided with an upward and outward arm or member 5, the latter adapted to slide laterally in the groove 6, carrying with it one edge of the music-desk '7, the groove 6 being out in the inner edge of the cross-piece 11 of the piano.
9 represents a part of a piano and forms the base on which the music can rest when leaning against the desk 7.
10 represents a part of a piano parallel with the part 9 and in the rear thereof.
In the drawings I have shown and in the description so far have referred to only one end of a piano and the piano music-desk. It is apparent that the other end of the musicdesk (not shown) is equipped in the same manner as that shown and described.
Fig. 1 shows the music-desk closed. Should it be desired to open the desk, the outer or left-hand edge of the desk 7 is lifted up and back,'when the desk 7 will assume the position shown in Fig. 2. In the operation just stated the point 5 has traveled along in the groove 6 to the opposite end of the latter, and the point 5 on the opposite end of the desk 7 has accomplished the same, and the members 1 have raised up at an angle and act as braces to the music-desk 7, as shown in Fig. 2.
It can be seen that the desk 7 can be easily opened or closed without the necessity of the operator adjusting any of the mechanism in order to have the desk 7 to retain the position desired.
From the foregoing description, taken in connection with the accompanying drawings, forming a part of this specification, the operation of my invention will be readily understood and its many advantages will be fully appreciated, and I will simply state that the device, by reason of its simplicity, attractiveness, and ease and efficiency of operation, will prove a useful and practical improvement, as I have fully demonstrated to my entire satisfaction.
My improvements herein shown and described are perfectly adapted to accomplish the results for which they are intended; but it is evident that changes in and modifications of the construction herein shown and described may be made and that analogous parts may be used to accomplish the same results Without departing from the spirit of my invention or sacrificing any of its many advantages.
Having shown and described the best construction of my improvements 'to me known at this time, what I claim as new, and desire to secure by Letters Patent of the United States, is-
The combination in a grand piano of a front base-piece, a rear member, forwardly and rearwardly extending cross pieces or members having horizontal guideways, a musicdesk adapted to lie horizontally in the opening when closed, members secured to the rear portion of said desk and having projecting arms which are loosely received in said guideways, whereby the desk is both slidably and pivotally supported, and a support for holding the desk in raised and closed positions, consisting of a member with hinged plates at the ends thereof, one of which is secured to the top of the desk and the other to the top of the front piece, whereby when said desk is raised, the rear end having the pivotal members will slide toward the front of the piano. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
