Title: Device for coupling the octave or other keys of a piano
IPC: G10C3/30
Filed: 1919-05-21
Abstract: 150,036. Muller, H., and Churchman, F. R. May 21, 1919. Pianoforte octave couplers.-A series of horizontal coupler levers for connecting octave or other keys lie beneath the key frame with their front ends supported by a sliding board fixed in any position by means of setting-keys, and their rear ends carrying vertically-disposed rods engaging with the regulating-screws of the playing- keys and the hammer action. A pedal raises the coupled levers so as to engage with the keys by means of a pin, and another pedal causes a pivoted frame carrying the rods to swing back in order to disconnect the kevs from the actions. Fig. 1 shows a vertical section of the apparatus; Fig. 2 is a part front view of the setting-device, and Fig. 3 a plan of the coupler levers. The front ends of the playing-keys a rest on spring-controlled pins c in the frame b extending to the coupler levers f. These are pivoted on the balance rail p, their front ends rest on the setting- board q between the pins z; their rear ends are each provided with a slot in which engages a pin h carried by a bar mounted on the supporting-board o, hinged at the back to the sides of the piano case. The front part of the board o carries the balance rail p and rests on the lifting-lever i, which is hinged to a similar lever k resting on a knife-edged rail l extending from side to side of the piano, on which the levers i, k are rocked by means of pedals m, n. Depression of the pedal n raises the board o and balance rail p, the keys and coupler levers then being connected by the pins c. By means of the wire i<2> the pedal n also swings back the pivoted frame e against the spring x and withdraws the rods y from under the hammer actions d<x>, thus disconnecting the playing-keys. The setting-board q carrying the pins z is mounted below the key frame b and moved sideways by knee boards q*. The desired setting- key t when depressed locks the catches w on the setting-board and is retained in the depressed position by a plate u and spring v until an adjacent key is depressed sufficiently to press back the plate and release the catches w. The shifting of the board q moves the coupler levers and balance rail transversely, and the latter has in addition a forward movement imparted to it by the surfaces p<2> bearing against the pins o<1> in the board o in order to prevent the leverage of the coupler levers from being altered.
