摘要
A drum beating assembly comprising a frame, including at least one pedestal; an axle carried by the pedestal to rotate relative thereto, the axle having an axis of rotation; a drum beater carried by the axle; a pedal operatively connected to the axle to rotate the axle and beater in response to pedal movement; a crank connected with the axle to rotate therewith; a return spring positioned to exert tension on the crank to yieldably resist axle rotation by the pedal, about the axis; and an infinitely adjustable connection between the spring and crank to allow adjustment of the position of spring tension exertion on the crank, about the axle axis, whereby the rest position of the beater relative to a drum surface may be infinitely adjusted.
