A drum pedal assembly is constructed with a beater assembly having a base
plate adapted to sit on the floor and having an outer end adapted to be
juxtaposed with a drum. Upright posts are mounted on the base plate and a
split shaft is mounted to an upright posts. The split shaft has a pair of
coaxial shaft parts having outer ends journaled in bearings housed in the
upright posts and axially juxtaposed inner ends journaled in a central
support member. A drum beater is mounted on each of the coaxial shafts.
The beater is driven by a pair of pedal assemblies, each provided with a
pedal pivoted mounted on a separate base plate and a pair of posts having
upper and lower ends mounted on the base plate. The post upper ends house
bearings and a shaft is rotatably mounted in the bearings. A linkage is
mounted on the pedal and is secured to a sprocket mounted on the shaft
for rotation of the shaft on depression of the pedal and connector
assemblies connect the pedal shaft with the beater split shaft to
transmit torque to the split shaft driving the drum beater.
