Abstract
A mechanism for producing a multiple number of drum beats from a single downward depression of a drum foot pedal. A slipping linkage is utilized to produce multiple oscillations of a shaft member during the continuous downward motion of the drum pedal. The drum mallet is attached to the oscillatory shaft and therefore produces a number of beats for each foot pedal depression.
