ABSTRACT:
A hand-held and hand-operated condiment grinder-dispenser includes a housing adapted to be held by an encircling grip of the user's hand, a grinding mechanism having a rotary grinding wheel and a driving mechanism having an operating lever coupled to the grinding wheel and arranged for a reciprocating motion composed of a manually-induced forward motion and a spring-induced return motion. An overrunning clutch couples the driving mechanism to the grinding wheel for transmitting a torque from the driving mechanism to the grinding wheel solely during the foward motions of the operating lever. The operating lever is positioned with respect to the housing such that it is included in the encircling grip of the user's hand.
