Abstract:
1. A piano action which includes a wippen having a wippen body, the wippen body being pivotally mountable via a first end of the wippen body on a first rail of a piano, the wippen including a wippen flange for mounting the wippen relative to the first rail and the wippen body including a first pivot point for pivotally mounting it to the wippen flange; a repetition lever pivotally mounted on the wippen body; a jack pivotally mounted on the wippen body; a boss arranged on the wippen body, the boss defining a second pivot point on which the repetition lever is pivotally mounted with the pivot point between the jack and the wippen body being a third pivot point, the arrangement of the pivot points being such that the first pivot point and the third pivot point are aligned along a line; and a repetition lever spring interposed between the repetition lever and the wippen body and pivotally mounted to the repetition lever, the repetition lever spring having a first limb which acts on the jack for restoring the jack to its rest position and a second limb which acts on the repetition lever for restoring the repetition lever to its rest position, the second limb being shorter than the first limb such that a free end of the second limb is out of engagement with the repetition lever and being shaped and dimensioned to move together with the repetition lever, and the first limb, when the wippen is in its rest position, in use, being substantially rectilinear along its length.
