Abstract

226,616. Axtens, R. A. Nov. 5, 1923. Pianoforte actions.-An upright action, readily adaptable bv the use of an additional wippen-like lever as a horizontal action, comprises a repetition lever 31 carried on a stationary pivot 32 and controlled by a stop 33 on a rod 34 which is pivoted on the wippen 6 and passes through the repetition lever, the dampers being mounted on a separate rail. The rod 34 is adjustable in length by a right- and left-hand nut 33x to which a spring 35 carried by the repetition lever is connected. Springs 41 acting on the hammers may be of double or multiple wires. The rails 17, 19, 25 are connected so that the action can be removed as a whole independently of the damper mechanism. The dampers 2 carry adjustable stops 8 on arms 9 pressed upwards by springs 11, and are actuated by arms 5 on the wippens. The dampers may be withdrawn simultaneously from the strings by a bar 61 and bell-crank 60 connected by a rod 63 to the loud pedal. The action is turned through a right angle when arranged for use as a grand action, the additional lever, which is acted on by the key, being connected to a rod carried by the lever 6 in place of the check 26, and the damper and check being arranged as usual in a grand action.
