Abstract
A water gun having a water reservior adapted to be partially filed with water includes a piston pump having an outlet connected to the water reservior. A hand-operated slide member can be reciprocated by an operator for the water gun, and a rack connected to the slide member drives a gear train connected to a flywheel. The flywheel is connected through a crank wheel to the piston of the piston pump, and as the operator withdraws the slide member to rotate the flywheel, the piston is reciprocated back and forth within the piston chamber of the pump to drive air into the water reservior. The flywheel maintains the reciprocating motion of the piston as the operator slides the slide member forward in preparation for another stroke. In this way, the pumping action is maintained by the flywheel as the operator reciprocates the slide member forward to begin another stroke.
