摘要： A drum pedal, having a drive assembly supported by a pedestal, may include a drive shaft, a rotatably adjustable drive ring, and a rotatably adjustable beater ring. In another aspect, a drum pedal may have a drive assembly supported by a pedestal comprising a journaled drive shaft, a rotatable bearing mounted off center of the drive shaft, a spring, and a biasing arm pivotally mounted on the pedestal, wherein the bearing and the spring cooperate to bias the arm toward a predetermined rest position. A linkage may operatively connect a foot board and the drive ring and may have means for selectively defining a connection to the foot board from one of plurality of positions. A beater may have a stem affixed to the beater ring. The beater may be actuated to a forward position when the foot board is depressed. The foot board may be biased toward a raised position and the beater may be biased toward a rearward position. In still another aspect, a drum pedal may have a drumward clamp, mountable to a bracket on the base, including a shaft, a rotatable arm, and a torsion spring for biasing the arm toward locking with a drum rim. The arm may be unlocked by rotating a lever connected to the shaft.

摘要： A bass drum beater may include a shaft having a length, a beater head fixable to a selected position along the length, and a connector engageable to the beater head and to the shaft to secure the position. The beater head may form an angle with respect to the shaft and the angle may be adjustable along a range, which may be about 20 degrees to either side of perpendicular. A bass drum beater may also include a shaft, a beater head having a drumward side and a hole to engage the shaft, a beater face attachable to the drumward side, and a means for holding the beater head in a longitudinal position and an angular position with respect to the shaft, wherein the longitudinal position and the angular position are adjustable. The means may include a bushing around the hole and a screw engaging the bushing.
