Definitions

• the primary object of the present invention is to provide a heating apparatus which is adapted to use gaseous fuel in such a manner as to store, retain and radiate the heat in a more eflicient manner than has heretofore been obtained 7with the use of a conventional type of stove or the like.
• Another object of the present invention is to provide a means for a gas burner heating apparatus which is adapted to retain and maintain heating elements in predetermined positions and to concentrate and connelthe heat so as to forceit to travel in certain well defined paths and permit it to escape into the room or. enclosure containing the vheating apparatus. ⁇ a y A further object is to provide means for supporting the heating elements in such a manner as to hang them in predetermined positions with respect to each other and prorange the heating elements in such a manner as to providefor automatic mixture of air,
