ABSTRACT:
In a Power Propelled Reciprocating Piston Pump Liquid Sprayer, there is a reservoir which is mounted on a frame to whose cross members wheels are attached by which the reservoir with its contents is propelled forward. The power unit mounted on the reservoir can be either electric or the gas powered engine type, it drives both the sprayer and the reciprocating piston pump mounted at the base of the reservoir. The pump employs a spring tensioned rubber piston with manual adjusting mechanism and is reciprocated by a power driven crank. On the induction stroke liquid in the reservoir is drawn through the sliding disc valve into the cylinder, on compression, contents is forced through a spring ball loaded valve into a separate chamber situated within the reservoir. From the chamber runs a tube to the exterior of the reservoir where a flexible hose is attached with a spray nozzle on the end. Spring loaded release valve with the pressure adjustment and faucet are situated on the chamber which enable any surplus fluid to be released back into the reservoir. The power to the rear wheels is transmitted via a "V" belt to a pulley attached to the crankshaft to which a sprocket is attached and from which power is further transmitted via a link chain, clutch and shaft arrangement, propelling the sprayer in the forward direction and reducing its speed to approximately walking pace.
