Abstract: The specification discloses a novel energy saving forced-air furnace. In contrast to previous forced-air furnaces, which ran only on gas or oil and in which approximately half of the energy derived from the burning fuel was lost through the chimney, the furnace of the present invention can run on coal, wood, gas or oil and retains a substantial portion of the heat which normally would be lost by the utilization of special tubing units and refractory plates. My furnace saves the greatest amount of energy possible by providing a heat chamber having a special tubing unit therein from the surface area of which heat generated in a stove chamber is transferred to a heat chamber and simultaneously through which exhaust gases air conducted from the stove chamber mounted below the heat chamber to the exterior of the furnace. Refractory plates are placed in a serial arrangement within the furnace heat chamber with spaces provided between them.

Abstract: The specification discloses a conversion system for a pedal operated cycle to provide a pedal operated cycle for use on ice and/or a motor operated cycle for use on snow, both with improved rear wheel apparatus, wherein a regular bicycle can be converted to a vehicle having a forward ski mechanism and an integral rear wheel and rearward ski mechanism. The combination rear wheel and rearward ski mechanism comprises a pair of brackets mounted to the frame in place of the rear wheel, which, in turn, has been remounted within said bracket. To the brackets there are attached, by way of braces, a pair of winter use skis.

Abstract: The specification discloses an improved washing machine having an outer wash tub adapted to be filled with water to a desired predetermined level. An inner perforated washtub is mounted in a concentrically spaced relationship to said outer wash tub and is adapted to receive the clothes to be washed. A compressor unit is adapted to reciprocate from the top to the bottom of said wash tub to briefly agitate the clothes and then to squeeze the water from them from the inside out.
