Abstract
821,174. Keyboard musical instruments. SLUYTER, A. March 25, 1957, No. 9638/57. Class 88 (2). Each key is connected to spring means which, when the key is depressed, is at first held by magnetic attraction until this is overcome by further depression of the key, whereupon the spring means is suddenly released to actuate the associated sounding element. In a pianoforte as shown, each key 1 carries a spring blade 5, which normally rests on a support 7 and carries at its free end an armature 6. On depression of the key 1, the spring blade 5 bends (Fig. 3), so that the armature 6 is held by a permanent magnet 8 and then, on further depression of the key 1, suddenly released to project a hammer 10 against the associated string 11. Depression of the key 1 raises a damper 14, and all the dampers 14 may be raised by means of a combshaped member 21 controlled by a pedal.
