ABSTRACT:
A volume controllable applicator is disclosed in the form of a self-contained spot gun for the application of pesticides and the like. The applicator includes an elongate applicator tube where terminates forwardly in a spray nozzle and rearwardly in a connection to a piston within a cylinder. A housing overfits a rearward portion of the applicator tube and the applicator tube is reciprocal relative to the housing by employing a pivotal, operating handle. An adjustable stop is affixed to the applicator tube forwardly of the housing to precisely limit and control the length of movement of the applicator tube relative to the housing in a manner to precisely control the volume of the effluent as it is pumped by the piston. A first one-way valve is connected to the cylinder inlet to admit the liquid chemical into the cylinder upon movement of the operating handle toward its suction position. A second one-way valve is secured within the piston to permit liquid flow through the interior of the piston upon movement of the operating handle toward its applicating position.
