SFECIFICATION forming part of Letters Patent No. 541,375, dated June 18, 1895.

Application filed April 17,1895. Serial No. 546,110- (No model.)

To aZZ whom it may concern.- pivoted at or near the center of each end Be itknown that I, KNUT A. MODEE, asubdirectly to the adjoining end Z), of the case ject of the King of Sweden and Norway, resid- A, without the interposition of an auxiliary iug at Boston, in the county of Suffolk and frame,in thefollowingmanner: To each end I), 5 State of Massachusetts, have invented certain of the case A, is secured by means of a screw 6, new and usefulImprovementsin Music-Desks Figs. 3 and 6, passing through its center, an for Pianos, Organs, &c., of which the followadjustable disk D, which is provided near its ing is a full, clear, and exact description, refperiphery with an inwardly projecting stud erence being had to the accompanying drawd, the two studs forming pivot-pins or pintles 6o ings, making part of this specification, in on which the music-desk B, is swung in and whichout as required; each disk D, being held im- Figure 1 is a vertical section through an upmovably in place when adjusted by a screw right-piano case and its music-desk having f, Figs. 3 and 6, passing through the same my improvements applied thereto. Fig. 2 is near its periphery, whereby any rotary move- 6; an enlarged elevation of the inner side of the ment of the disk on its center screw 0, is premusic-desk and the portion of the piano-case vented. to which it is applied. Fig. 3 is a horizontal The music-desk B, is provided on its inner section on the line 3 3 of Fig. 2.

Fig. 7 cured in place by screws 1', the outer portion is an enlarged sectional detail of the spring 10, of said plate, which lies flush with the edge retaining device by which the music-desk is of the desk, being provided with an open held in an open or closed position. Fig. 8 is flaring-mouthed slot 7t, for the reception of an enlarged elevation of one of the desk-sup the stud in line therewith, which fits snugly 7 porting devices shown in Fig. 2. therein, as shown in Figs. 3 and 4, when the My invention relates to musicdesks for desk is applied to the front of the piano-case pianos, organs, and other similar musical in- A, said stud d, being locked in place within struments, and has for its object to simplify the slot is, which forms a bearing therefor, by and improve the'method of hanging the same a latch or lever G, pivoted at m, to the inner 8o 0 within the front of the case, whereby the neside of the music-desk B, and provided with a cessity of employing an auxiliary removable knob or handle 12, the outer end 15, of said frame to hold the desk in place, as has herelatch being bent inward at a right angle so tofore been customary, is avoided. that when it is forced down as shown in Figs.

To this end my invention consists in a de- 3 and 4, it will fit snugly against the pin (1, 85 5 vice of novel construction for hanging or the desk being thus held within the case A, pivoting the music-desk to the case of the inin such manner that it will be free to swing strument in such manner as to enable it to on the studs or pivot-pins d, but cannot be be easily removed and replaced as hereinafter removed until the latches G, are swung upmore fully set forth; and my invention also ward as shown at the right hand side of Fig. go

40 consists in an improved spring retaining- 2, to enable the slotted plates h, to be withcatch for securely holding the music-desk in drawn from the said pivot-pins. The recesses an open or closed position and preventingthe g, within which project the ends 15, of the same from being swung outward beyond the latches G, as shown in Fig. 3, are of sufficient proper limit, as hereinafter set forth and spesize to permit of the necessary movement of 5 5 cifically claimed. said latches, which movement is limited in In the said drawings, A represents an upeither direction by the contact of the bent right piano-case, to the upper portion of the ends 15, with the tops and bottoms of the refront of which is fitted the swinging musiccesses g. desk B, forsnpporting the sheet music, book, When the music desk 'isto be removed from I00 or other article. This music-desk B, which is the case A, it is simply necessary to lift its adapted to be swung outward at the bottom, is cover or top H, and reach down and raise the latches G, with the hand, thus releasing the desk which can then be easily taken outof the case, and when replaced the latches are swung down in the same manner, the operation being performed with great facility; and by the employment of the above described device the removable auxiliary frame within which the music-desk has hitherto been hung by means of ordinary mirror-hinges, is entirely dispensed with; thus simplifying and cheapening the construction. It will be seen that by turning the rotary disks D, upon their center screws 0, the height of the pivot-pins d, can be independently varied to nicely adjust the music-desk to the opening in the case within which it fits, and when properly adjusted said disks are prevented from turning projecting arms 19, 10, Figs. 1 and 7, each of which is provided with two concave notches q, r, for the reception of a rounded projection s, at the free end of a fiat springL, which exerts an upward pressure against said arm p, and engages the inner notch q, when the desk is closed in, and the outer notch 0", when the desk is swung out into position for use, as shown in Fig. 1; the spring thus forming a friction retaining-catch for holding the desk securely either in an open or closed position, while owing to the concavity of the notches q, r, and the shape of the end 8, of the retaining spring, a very slight pull or push on the desk according to its position will disengage the notch from the springas described.

In order to prevent the music-desk from being swung outward at its bottom beyond its proper limit, the end 20, of the spring L, is preferably turned under, as shown in Fig. 7, so that it will, when depressed, strike the portion of the casing beneath it, which thus forms a stop to prevent the end of the spring from being depressed sufliciently to allow of the passage thereover of the outer downwardly projecting hook-shaped end 25, of the arm p, connected with the desk, the further outward movement of which is thus prevented.

(hat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination with a piano or organ case having its sides provided with inwardly projecting pivot-pins or pintles, of a musicdesk having recesses at its opposite ends provided with plates having open slots for the reception of said pivot-pins and forming bearings therefor, and pivoted latches adapted to be swung over the said pivot-pins to lock the same within their slotted bearings, substantially as set forth.

2. In a piano or organ case, the combination with the swinging music-desk and its bearings, of a pair of rotary disks each provided on one side of its c enter with a pivot-pin or pintle for supporting said desk, said pivot-pins projecting inwardly from the sides of the case and being adjustable in height by rotating said disks on their centers, and means for securing said disks when adjusted, substantially as described.

3. The combination with a piano or organ case provided at its ends with rotary disks D, turning on center pins or screws 0, and each having a pivot-pin or pintle d, on one side of the center, whereby it is made adjustable in height by turning said disk, and the fastening screwsf, for holding the disks when adjusted, of the swinging music-desk B, having recesses g, at its opposite ends provided with plates h, having open slots k, for the reception of the said pivot-pins, and the latches G, adapted to be swung over the pivot-pins to lock the same within the slots 7c, all operating substantially as and for the purpose set forth.

Witness my hand this 15th day of April,.v

KNUT A. MODEE. In presence of P. E. TESCHEMACHER, J ULIEN W. Vosn.
