Abstract

1,119,381. Keyboards. M. E. JOHNSON. 17 May, 1966, No. 21957/66. Heading G5J. The rest position of each of a number of piano keys is determined by a felt pad 65, the height of which is screw-adjusted and on to which the key is drawn by the sticker 47. Each key pivots on a balance rail 25 on pins 51 which pass through circular holes 54 in the key bottom and widen into rectangular slots which prevent sideways key movement. Pins 50 on the front rail 21 engage similar recesses 52 in the keys. The front rail itself is provided with pairs of screws along its length one of which pulls the rail down and the other forces it up. Adjustment of these screws along the keyboard ensures that the front rail is flat.
