FALL-BOARD FOR UPRIGHT PIANOS.

SPECIFICATION forming part of Letters Patent No. 247,473, dated September 27, 1881 Application filed July 28, 1880. (No model.)

To all whom it may concern:

Be it known that I, GHARLEs E. BOURNE, of Boston, Massachusetts, have invented an Improvement in Fall-Boards for Upright Pianos, of which the following is a specification.

The object of my invention is to so construct the fall-board of an upright piano that it maybe thrown back in opening the instrument without interfering with the music-rack, and also to so connect it with the music-rack that the latter will be put in position automatically by the opening of the instrument.

In the accompanying drawings, Figure 1 is a side View of an upright piano containing my invention, showing the position of the parts when closed. Fig. 2 is a similar view of the instrument on a larger scale, showing the position of the parts when open, the dottedlines alsodndicatin g their position when closed. Fig. 3 shows one of the arms to which thefront portion of the fall-board is attached. Fig. 4 is a front view of the instrument, showing the position of one of these arms at the side of the fall-board.

The fall-board is made in two parts, A and B, united by hinges opening upward. The front portion, A, is attached to the case of the piano by two arms, (3 0, one on each side, fastened rigidly at the upper ends to the sides of the tall-board, and pivoted by means of open slots at the lower ends to studs or pins in the case of the instrument. The rear end of the part B is also attached to the case above it by when the fall-board is thrown back in opening the instrument.

Behind and above the fall-board, and pivoted to the case of the instrument,is the curved lever E, whose lower end is in contact with the 40 back side of the fall-board B, while the upper end rests against the back side of the musicrack F, which is suspended by hinges at its upper edge in the usual manner.

Attached to the musicrack is a spring, G, 5 the other end of whichis fastened to thepianocase, so as to aid in bringing the music-rack back to a perpendicular position when the pressure of the lever E is withdrawn.

The construction and arrangement of the parts are such that when the fall-board A is raised and thrown back in opening the instrument the part B is carried backward and downward within the case, allowing the part A to be turned up under the music-rack without interfering with it. At the same time the pressure of the partB upon thelever E throws the lower end of the music-rack outward into place.

WVhat I claim, and desire to secure by Letters Patent, is

1. The jointed fall-board A B, suspendedby the arms 0 O D D, substantially as and for the purpose described.

2. The fall-board A B, lever E, and musicrack F, combined and arranged substantially as and for the purpose described.
