Abstract: A pneumatically operated fastener-driving tool, particularly adapted for nailing drywall to the framing of a building, comprising a housing, a reciprocator assembly mounted within the housing, and a piston mechanism mounted within the reciprocator assembly for axially driving the fastener into the drywall and underlying framing member. Upon actuation of the tool, the piston is pneumatically driven through a fastener-driving stroke and the reciprocator is reactively driven in an opposite direction. The oppositely driven reciprocator assembly absorbs recoil energy during the piston's driving stroke without transmitting an appreciable amount thereof to the housing, thereby substantially precluding housing recoil during driving of the fastener. At the end of the driving stroke, the reciprocator engages and is decelerated by the piston, thereby reducing housing recoil subsequent to the driving of the fastener.

Abstract: A fuel supply system for internal combustion engines whereby a liquid hydrocarbon fuel is supplied to an enclosed pressure chamber, and wherein the chamber the liquid fuel is heated to within temperature limit of 95% plus or minus 5% of that said fuel's refined distillation end point. At that temperature high vapor pressure exists within the enclosed compression chamber. The resulting vapor is conveyed to the carburetor venturi system and combustion chamber in true vaporous state by means through a cooperating system of primary and secondary pressure reducing regulators. Attached onto the interior wall of the compression chamber is a liquid fuel dispensing pump, which maintains a constant fuel level within that chamber. Energy to operate the pump is derived from surrounding pressure within the compression chamber.

Abstract: A pneumatically operated fastener-driving tool, particularly adapted for nailing drywall to the framing of a building, includes a housing, a reciprocator assembly mounted within the housing, and a piston mechanism mounted within the reciprocating assembly for axially driving the fastener into the drywall and underlying framing member. Upon actuation of the tool, the piston is pneumatically driven through a fastener-driving stroke and the reciprocator is reactively driven in an opposite direction. The oppositely driven reciprocator assembly absorbs recoil energy during the piston's driving stroke without transmitting an appreciable amount thereof to the housing, thereby substantially precluding housing recoil during driving of the fastener.
