UNITED STATES PATENT OFFICE.

AZARIAII HORACE HASTINGS, OF NEIV YORK, N. Y.

MUSIC-DESK FOR PlANO-FORTES, 800.

SPECIFICATION forming part of Letters Patent No. 439,87 5, dated November 4, 1890.

Application filed January 29 1890.

To all whom, it may concern:

Be it known that I, AZARIAH HORACE HAST- INGS, a citizen of the United States, residing at New York city, in the county and State of New York, have invented certain new and useful Improvements in Music -Desks for Piano-Fortes, &c., of which the followingis a description.

This invention relates more particularly to that class of music-desks for piano-fortes and other musical instruments in which the desk proper is arranged in an upright portion of the frame of the instrument and is folded flat therein when not in use, and is capable of being extended by a downward and outward sliding motion for use in receiving a piece of music.

The invention consists in a downwardly and outwardly movable desk, combined with a cranked rod for holding the desk in its positions of use and disuse, as I will now proceed more particularly to set forth and finally claim.

In the accompanying drawings, illustrating my invention, in the several figures of which like parts are similarly designated, Figure 1 is a perspective view, looking at the rear of the device when not in use. Fig. 2 is a similar view with the desk in position for use; and Fig. 3 is a perspective view, looking at the front with the desk in position for use.

a may represent any upright portion of a musical instrument. In this frame is arranged the desk 19, to resemble when not in use a panel of the frame, if so desired; but for purposes of simplicity I will confine this description to a desk thus arranged. The rear of the frame is provided with pins or pivots c, which enter longitudinal slots or grooves d, made in opposite edges of the upper portion of the desk.

6 is a cranked rod or shaft, the ends of which Serial No 338,505. (No model.)

are journaled in the back of the desk Z), and the said cranked rod is secured between its ends and at the dip in the bend to a bracket f, made fast to thelower portion of the frame a.

The lower portion of the desk may be provided with a bar or offset g to support the edge of the piece of music, such as sheet-music or a book.

As thus constructed the desk may be pulled into position of use by catching hold of the bar g and exerting pressure outwardly, the cranked rod 6 serving to throw the desk down and outwardly under such pressure, its grooves or slots d, working upon the pin 0, permitting this motion. By a reverse movement the desk may be elevated and returned to its position in substantial alignment with the frame.

For purposes of greater securityin holding the desk in either position, I prefer to add to the cranked rod an eccentric projection h, which may be engaged by a spring-finger 2', having sufficient pressure to lock the cranked rod in either of the two positions before mentioned.

IVhat I claim is- The combination, with a frame and a desk adapted to be moved vertically thereof and toward and from the same, of a cranked rod journaled to the desk and to the frame and provided with an eccentric projection to lock the cranked rod and the desk in either of the two positions which they may be made to assume, and a spring co-operating with the eccentric projection, substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand this 27th day of January, A. D. 1890.

A. HORACE HASTINGS.
