ABSTRACT:
A drive mechanism for converting a reciprocating angular movement into one directional angular movement is disclosed for driving a shaft in a submersible cleaning device. In particular, a positive engagement clutch converts an alternating pivotal or angular motion of a shaft to a unidirectional circular motion of a driven gear. The shaft is affixed to a collar formation comprising pockets in which pawl elements are movably placed. The pawl elements engage teeth of a periphery ring that encloses the collar. The driven gear is affixed to the ring. The pawl elements operate in a dense medium such as the water of a pool in which the device is operating. The water imparts a high degree of inertia to the pawl elements and cause them to engage in the peripheral ring during the alternating motion of the shaft. Rotational movement of the driven gear to one direction is accomplished using a second pawl engaging a ratchet affixed to the periphery of the ring. With this single rotation of the driven gear, a number of cleaning device functions can be performed including, for example, a dislodgement mechanism.
