Abstract

188,333. Frankel, F. Nov. 2, 1921, [Convention date]. Pianoforte sound-boards.-A metal soundboard 1 which has a series of corrugations 2 projecting from the front and is fixed to a rim which both contracts the edges, thus rendering the sound-board slightly convex, and also sets up a stress in the sound-board, is provided on the rear with wooden ribs 3, which are arranged transversely to the corrugations and maintain the plane parts between the corrugations in alignment on the fiat curve of the sound-board. The ribs 3 are secured by screws 4 at the intersections with the corrugations, and by cement.
