Abstract

23,539. Bruer, J. J. Oct. 23. Pianofortes, actions for. The hammers and dampers are reversible and rotatable, and may be made entirely of felt, the hammer butt being connected to both the jack and the rail by adjustable springs. Fig. 1 shows the application to an upright piano. The hammer e is made with two or more faces, and is rotatably mounted in a spring clip which also has small projections fitting recesses g to prevent rotation, except when it is desired to change the working face. The clip i is swivelled to the socket h, turned to suit the inclination of the strings, and fixed by solder. The socket h is fixed to the shank by means of a screw or pin k with a suitably weighted head. The dampers are mounted in a similar manner. A screw l adjusts the pressure of the throw-off spring m, which rests against an arm z with a cupsocketed end. The jack b is connected to the hammer butt c by means of a repetition spring n, passing through the jack, and a lever p, adjustable by a screw q. The invention is applicable to horizontal pianos.
