  • Patent number: 4089642
    Abstract: The space heater of the invention features an improved motor-transformer package which may be easily applied to and removed from the heater, as an integrated unit. The design and mount of this package makes it extremely easy to service and insures that in the placement and operation thereof the total package will be surrounded with an insulating flow of air, the cooling effect of which guarantees a longer and more useful operating life for the included components and related apparatus. In the preferred embodiment illustrated, the motor and transformer elements of the package are connected, in a superposed relation, to opposite sides of a mounting plate the design of which essentially dictates the required placement of the package in a heater housing.

  • Patent number: 4081238
    Abstract: A compact, relatively midget sized, portable heater a stable base for which is provided by its fuel tank per se. The tank features a plug fit filter tube formed to facilitate the connection of a fuel supply line. Preferred embodiments of the heater are characterized by plate formed air deflector fins which are arranged to most effectively control the delivery of air to and about the discharge from a simply mounted and constructed fuel nozzle at the entrance to a combustion chamber. The illustrated embodiment shows the fins as included in a bracket-type support for the fuel discharge nozzle and on a deflector plate which defines the entrance to the combustion chamber to which it mounts. The relationship of parts enable the use of a minimal amount of energy for a given application.
