FREDERICK WV. HEDGELAND, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE W. WV. KIMBALL COMPANY, OF SAME PLACE.

FALL-BOARD FOR MUSECAL INSTRUMENTS.

SPECIFICATION forming part of Letters Patent No. 594,012, dated November 23, 1897.

Application filed September 1'7, 1897. Serial No. 652,020. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK W. HEDGE- LAND, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Fall-Boards for Musical Instruments, of which the following is a specification.

This invention relates to the construction of a fall-board capable of being folded upon itself and moved into a recess in the case of the instrument.

The invention consists in the novel features of construction shown in the accompanying drawings and set forth in the claims.

The drawings show atFigures 1 and 2 vertical sections of the fall-board and the adjacent parts of the instrument, the fall-board being shown in different positions in the two figures.

In said drawings, A represents one of the ends, B the front, C the finger-board, and D the top, of the instrument-case. E E are the keys. The fall-boardis composed of three sections F, G, and H, the latter being the innor section and pivotally attached at each end to swinging levers J. Each lever J is supported upon a pivot K, secured in the end of the case or otherwise supported. The section H is provided with an upright extension H, which when the instrument is closed sets close under the top D. The middle section G is hinged to the section H at the outer surface of those sections, as at G, so that section G can be folded over upon section H, as shown. The outer section F is hinged to section G at the lower surface of those sections, as at F, so that section F maybe folded over upon section G after the latter has been folded upon section H. Then thus folded, the three sections lie one on the other, as shown in broken lines in Fig. 1, and the entire fallboard may then be pushed into the recess in the case above the board C and under the top D, as plainly indicated at Fig. 2. The section F is provided with a downward exten. sion F which when the board is folded, as above described, extends down in front of both of the sections Gand H and entirely conceals them from view, so that at such times no hinges or metal parts employed in the fallboard are Visible, and as this extension F may be handsomely veneered or polished it presents a very finished appearance in the folded position. The extension H and section H are adapted to conceal the opening in the case when the board is unfolded.

Oneadvantage attending my construction is that my improved fall-board when folded enters the case but a short distance, so that the major portion of the space back of the fall-board can be utilized for the sounding devices or action of the instrument.

I claim- 1. The combination in a fall-board, of three hinged sections F, G and H, the front section having an extension adapted to cover the edges of the other two sections when folded, substantially as specified.

2. The combination with an instrument hav- 7o ing a recess in its front adapted to receive the folded fall-board, of a fall-board composed of three hinged sections F, G and H, substantially as specified.

3. The combination with an instrumenthaving a recess in its front adapted to receive the folded fall-board, of a hinged fall-board composed of three hinged sections F, G and H and swinging levers J attached to the inner section, substantially as specified.

4:. The combination in a fall-board of three hinged sections F, G and H adapted to fold together, as set forth, said section F having a downward extension F and said section H having an upward extension H, substantially as specified.

5. The combination of an inner section H supported by swinging levers within the case, an intermediate section G hinged at its top to section H, and a front section hinged to section G at its under surface, with a musical instrument having a recess adapted to receive said sections when folded one upon the other, substantially as specified.
