MUSIC-RACK FOR UPRIGHT PIANOS.

SPECIFICATION forming part of Letters Patent No. 313,417, dated March 3, 1885.

Application filed October 21, 1884.

(No model.)

ets or hinge-pieces to which they are hinged Be it known that I, GEORGE M. GUILD, of at F F. The pin or rod in the part a of the Boston, in the county of Suffolk, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in Upright Piano-Fortes, andI do hereby dcclarcthe same to be described in the following specification and represented in the accoi'npanying drawings, of which- Figure l is a longitudinal section, and Eig. 2 a transverse section, of the upper portion ofthe case of an upright piano, with my invention applied to the music-rack and upper lid of suoli case, the nature of such invention being defined in the claim hereinafter presented.

In the above-mentioned figures, the musicrack when down in a vertical position does not close within an opening in the case; but in Fig. 3 it is shown as applied to the case in such manner as to admit of the rack when down going` within a recess or opening for its reception.

Instead of having the music-rack hinged at its upper edge to the case or to the top ol` an opening therein for reception of such rack, when the fall board is so arranged with such rack and opening that on such fall-board being turned back to uncover the keys and the rack swung forward out of its opening, the rack shall be caused to rest upon the fallboard and by it be supported in an inclined position. I, in carrying out my present invention, connect to the rack at its back two curved arms, to extend upward therefrom to hinge pieces or brackets projecting from the part of the case which is directly above the rack, such arms being attheir upper ends hinged or pivoted to such hinge pieces or brackets. I form vertically directly over one or each of the arms a hole, in which I place, to slide freely in it, a pin or rod to extend from the arms up to the lid. The arm under such pin is curved or so formed or inclined as to cause the pin, when the music-rack is drawn forward, to act as a cam to force the pin or rod upward and by means of it the lid.

In the drawings, the piano-case is shown at A, the music-rack at B, the fall-board at C, and the lid at the upper part of the case at D, such lid being hinged in the usual manner to the case and covering an opening in its top. The curved arms projecting from the music-rack are shown at E E, and the brackcase from which the brackets project is shown at G as extending upward from the curved arm to the lid, there being to each curved arm, or to but one only of them, such a pin. By having the curved arm inclined, as shown at b, in the part which bears against the pin while the music-rack is being drawn outward, the pin will, by such part b, be moved upward as the rack may advance, and consequently will force the lid upward to open the case at top in order to allow the sounds emitted by the strings when struck by the hammers to freely escape through the opening made by raising the lid.

In Fig. 3, c denotes the opening in the case for reception ofthe inusic-rack when in a vertical position, while in Fig. 2 the case has simply openings d in it in rear of the musicrack, and of sufiicient size for reception and working of the curved arms.

On drawing the music-rack forward and turning back the fall-boad, the latter will serve to support the rack in an inclined position when it may be resting at its lower edge on the said fall-board.

I do not herein claim a music-rack hinged at its upper edge to the top of an opening in the piano-case and arranged with the fallboard in such manner that the latter, when turned back, shall be lmade to support the rack in an inclined position, such being as described and represented in Letters Patent No. 243,700, granted on July 5, 1881, to me.

I claim- In the upright piano-case having a fallboard adapted to support the music-rack when drawn out into an inclined position, the coinbination of the bent or curved arms projecting rearward and upward from the musicrack and hinged to the piano-case or to brackets iixed thereto, with a pin extending from the upper edge of one or each of such arms to the hinged lid of the case, the whole being so that on the music-rack being drawn forward the lid shall be opened or forced upward, as explained, such lid descending and closing the opening in the top of the case on the music-rack being moved back to its normal or upright position.
