Abstract

1,099,280. Piano action. MALMSJO PIANO AB. Nov. 19, 1965, No. 49239/65. Heading G5J. Individual sections of a piano action are attached to a metallic action rail by fastenings which are displaceable along a guide in the rail. As shown, whippen 24, damper lever 26 and hammer butt 28 are respectively fulcrumed on flanges 18, 20 and 20 integral with a carrier 16 which is fastened to the action rail by bolts 38 through the carrier and nuts 36 engaging within a groove 32 in the rail. Each flange is deformable to enable adjustment of the whippen, damper lever and hammer butt after mounting the carrier 16 on the action rail. The carrier is prevented from turning by projections which engage guide grooves 42. The escapement action of the jack 44 is produced by engagement of spring 64 with pad 62 on the carrier. The bent portion 66 at the end of the spring prevents over-throw of the jack and helps spring 52 to restore it. Spring 78 acting on a metal plate or silk pad 80 on the hammer butt restores the hammer.
