US Patent 7861891 Apparatus for discharging a stream of fluid

A device for discharging a stream of fluid is presented. The device includes a water pump handle and trigger mechanism that are selectively connectable to a ratchet mechanism to allow incremental discharge of the fluid. The device includes a body accommodating a water reservoir and a fluid line extending through the body. A spring urges the ratchet bar to allow the discharge of fluid during the spring-induced movement of said ratchet bar. A trigger mechanism arrests the spring-induced movement of the ratchet bar.
