SO UNDlNG-BOARD SUPPORT FOR PlANOS.

SPECIFICATION forming part of Letters Patent No. 593,039, dated November 2, 1897. Application filed December 9, 1896- Renewed August 18, 1897. Serial No. 648,721. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY ZIEGLER, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Sounding-Board Supports'for Pianos, of which the following is a specification.

This invention relates to an improved sounding-board support which can be used for pianos of all kinds, but which is more especially adapted for upright pianos.

Ileretofore the sounding-boards were secured at their edges to the supporting main frame, which, however, was objectionable to some extent for the reason that at those portions of the sounding-board where the sounding-board bridge is situated close to the edge of the sounding-board the tone of the instrument is less resonant than at those portions where the bridge is located at some distance from the edge. Pianos have been made in which the sounding-board was isolated en.- tirely from the main frame at the edge, but this has the result that the sounding-board makes transverse vibrations which produce a weak and shaky tone quality.

The object of my invention is to overcome the objections to the sounding-board supports heretofore used and to furnish an improved support for sounding-boards by which freer and fuller vibrations of the sounding board are obtained and the vibrating portions of the board extended beyond the soundingboard bridge.

My invention consists of a sounding-board for pianos which is supported at the points where the bridge is located close to the edge by a bracket-support that extends from the edge of the sounding-board inwardly to the main frame, as will be fully described hereinafter and finally pointed out in the claim.

In the accompanying drawings, Figure 1 represents a front elevation of the treble por tion of an upright piano with my improved sounding-board support. Fig. 2 is a vertical transverse section of the same on line 2 2, Fig. 1. Fig. 3 is a detail section of my improved sounding-board support, shown as applied to the sounding-board of a square or grand piano; and Fig. 4 is a detail section showing the sounding-board support heretofore in use.

Similar letters of reference indicate corra sponding parts.

Referring to the drawings, Arepresents the supporting main frame of an upright or other piano; B, the string-frame; O, the soundingboard; 1), the sounding-board bridge, and E the support for the edge of the soundingboard, which support was heretofore made at right angles to the sounding-board and the main frame, as shown in Fig. 4.

In my improved construction the soundingboard support E is made in the shape of a bracket and extended inwardly from the edges, its middle portion being inclined toward the sounding-board and the stringframe, the upper portion supporting the edge of the sounding-board, while the lower portion rests ,on the main frameA at a point below or beyond the sounding-board bridge D, as shown in Fig. 2. The inclined bracketsupport E has the advantage that the vibrating part of the sounding-board beyond the bridge is extended for the reason that instead of a direct rigid support a yielding support is substituted which permits the soundingboard to vibrate more freely and fully than heretofore.

My improved bracket-support is of special advantage at those portions of the soundingboard where the sounding-board bridge approaches close to the edge of the soundingboard; but it'may be extended around the edge of the entire sounding-board, as thereby the portion beyond the sounding-board bridge can partake in a freer and fuller manner in the vibrations of the sounding-board than by the construction heretofore in use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent As an improvement in pianos, the combination, with the main frame of a piano, of a sounding-board and a bracket-support for the edge of the same, said bracket-support ex tending inwardly from the edge of the sounding board to the main frame, substantially as set forth.

In testimony that I claim the foregoing as myinvention I have signed my name in presence of two subscribing witnesses.

HENRY ZIEGLER.
