Portable heater

A fuel filter unit particularly advantageous for insertion in the means defining an outlet opening in a fuel tank of a device such as a space heater comprising a tubular unit, said unit having a fuel passage incorporating filter means and being characterized by an outer peripheral surface a portion of which embodies resilient means providing for a plug fit of said unit in said means defining said outlet opening and means to form a seal between said unit and the means defining the outlet opening in which it is plug fit and one end of said unit embodying means providing for a slip fit of a fuel supply line and anchoring means resisting displacement of the fuel supply line, once it is applied.

A portable space heater comprising a fuel tank mounting means defining a combustion chamber having at one end thereof means defining an inlet thereto and at the opposite end thereof means defining an outlet therefrom, a strap-like structure connected with said means defining said combustion chamber to bridge the inlet thereto, said strap-like structure having a central opening in line with the inlet to said combustion chamber, a fuel nozzle, an adapter coupled to and forming an axial extension of said nozzle, said fuel nozzle and said adapter, in the coupling thereof, being applied to have portions thereof abut relatively opposite faces of said strap-like structure whereby to clamp a portion of said strap-like structure therebetween and position the discharge end of said nozzle at and in a generally coaxial relation to the inlet to said combustion chamber, means for directing fuel from said tank and to said adapter for movement through said nozzle, means for ignition of said fuel on its discharge from said nozzle and means mounted on said tank for effecting a directed flow of air under pressure to said nozzle and said combustion chamber to insure ignition and support combustion.

A portable heater comprising a fuel tank mounting means defining a combustion chamber, said combustion chamber having an inlet thereto and an outlet therefrom, means in connection with said combustion chamber mounting a fuel nozzle and having in connection therewith means for delivering fuel from said tank to and through said nozzle, means on said tank for delivering air to and about said combustion chamber and said nozzle, means for igniting the fuel delivered from said nozzle for combustion thereof in said combustion chamber, said fuel tank per se forming the base of said portable heater and being characterized by a depth providing that there is no appreciable variation in the head pressure within the tank as the fuel therein drops from its highest to its lowest level and said fuel tank mounting on the upper surface thereof an elongated bracket which is generally U-shaped in transverse section and positioned intermediate of and spaced from the respective ends of said fuel tank, said bracket forming a base for said means defining a combustion chamber and positioning to one end thereof while the remainder thereof extends over said tank in elevated spaced relation thereto.
