Maine, a corporation of Maine Application April 30, 1943, Serial No. 485,226 4 Claims. ‘ (Cl. 220-55) 1 2 . The present invention relates to improvements in casing for truck and freight car heaters, and has for an object to provide an improved heater for portable use in trucks, freight cars and the like, to keep perishables from freezing. Another object of the invention is to provide such a heater constructed and built into a pro in the secondplace as a re?ector to cause the heat to spread horizontally outward in all radial directions and upwardly.‘ In~this last function the disc l8 cooperates withan inverted cone l9 which constitutes a spreader, serving to spread the ?ame and heat,_ and consequently creates more radiation and circulation of heat. The burner i4 is con?ned between the disc I8 and tection screen which extends wholly about the heater and is equipped with disappearing handles the cone l9 and the-parts l8 and I9 serve to co for carrying the same. 10 operate to divert the heat upwardly and out A ‘further object of the invention is to provide wardly in all radial directions.

The front panel 33 is not secured -.to the case but is readily removable for servicing and -re placements. The containers l0 and H are of course also removable when-‘empty for-substitu tion by other replenished containers. and the front panel 33 may be removed to give complete access to the equipment, thus enabling an exhausted container to be removed without _interrupting the service of heat maintained by the reserve container.
