Abstract
A reversing drive for a triple action agitator is provided in which the agitator has an upper portion with helical grooves formed therein and a thruster barrel is received over the agitator upper portion. The thruster barrel has inwardly directed pegs which cammingly ride in the grooves to provide vertical movement to the thruster relative to the agitator. A two position clutch has an alternating rachet-type engagement between the agitator and the thruster to prevent rotary motion between the thruster and agitator when the agitator is rotating in a first direction, but to permit rotary motion between the thruster and agitator when the agitator is rotating in a second direction when the clutch is in a first position. When the clutch is in the second position, relative rotary motion is permitted when the agitator is rotating in the first direction and is prevented when the agitator is rotating in the second direction.
