ABSTRACT:
An apparatus for discharging a stream of fluid includes a water pump, a trigger mechanism, a ratchet mechanism, a fluid reservoir, and a secondary fluid chamber. A pump handle is used to move a piston that draws the fluid from the fluid reservoir into the secondary fluid chamber before discharge. The pump handle is also used to selectively connect the trigger mechanism to the ratchet mechanism to allow incremental discharge of the fluid from the secondary fluid chamber. A handle is selectively connectable to the ratchet mechanism and configured to manually move the ratchet mechanism to a first position against the urgency of the spring. The handle is also selectably connectable to a pump mechanism, the handle being movable from a first position to a second position, wherein the handle is connected to the ratchet mechanism in the first position and connected to the pump mechanism in the second position.
