ABSTRACT:
Apparatus for safely dispensing flammable liquids from containers. A reciprocating piston, slidingly positioned within a cylinder, draws flammable liquid from a sealed drum and dispenses the liquid from a spout member extending from the apparatus. A flame-arresting device operably positioned within the apparatus disperses any flame advancing into the cylinder. A dip tube extends from the apparatus into the flammable liquid within the drum. In a preferred embodiment of the invention, the reciprocating piston dispenses flammable liquids on the upstroke only, thus preventing accidental or inadvertent discharge of the liquid.
