ABSTRACT:
A drum pedal, having a drive assembly supported by a pedestal, may include a drive shaft, a rotatably adjustable drive ring having an arm, and a rotatably adjustable beater ring. A link may connect a foot board with the arm. 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 another aspect, a drum pedal may have a drive assembly with a cam, having a slope, mounted on a drive shaft. The cam and a spring may cooperate to bias a cam follower toward a predetermined rest position. An adjuster may be provided to easily change the tension of the spring. In still another aspect, a drum pedal may have a drumward clamp 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.
