Abstract

Abstract A "Steam Powered Stove" which burns any suitable fireplace fuel in a standard stove firebox. Directly above the firebox is a water boiler tank. This tank has tube penetration extending into the firebox for increased steam generation efficiency. Steam pressure is directed to a regulator which can readily be adjusted to the desired pressure by turning a long stem handwheel. Steam pressure strikes the blades of a turbine causing fans to rotate. Cold air is drawn by the fans through a heater box and then into the atmosphere. A removable pulley can be attached for driving other equipment. Water level is maintained by an inherent water fill tank. Used steam is exhausted up the vent pipe.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 303 words
A Steam Powered Stove comprising: A. a stove means having a liquid containing portion therein, a means for feeding said liquid containing portion, a means of exhausting steam, and a steam pressure safety valve means, B. a steam pressure regulator means having a long stemmed hand wheel thereon whereby steam pressure may be conveniently adjusted and set at various pressures, said regulator means further consisting of a nozzle attached thereto whereby steam pressure may be directed to a turbine, C. a turbine means having a body with a plurality of blades extending therefrom said body being centered about a shaft such that said turbine blades are equidistant from said shaft's centerline said body being securely mounted on said shaft and generally centered thereon whereby torque may be transmitted to a plurality of fan means positioned on said shaft, said shaft being supported from a plurality of support blocks having bearings mounted thereon said fan means being securely mounted on said shaft and are positioned and designed to blow hot air from heater boxes, D. a plurality of heater boxes positioned adjacent to the firebox and liquid containing portion of said stove means and in thermal communication therewith whereby the heat of conduction, convection, and radiation may be transferred therethrough, said heater boxes having a plurality of secreened cold air openings near the bottom portions thereof and hot air discharge openings near the upper portions thereof, said hot air discharge openings being in alignment with said fan means, said heater boxes rising to a vertex at the approximated centerline and above said shaft, e. and a removable torque transfer means or pulley whereby other equipment may be driven by said stove means, said torque transfer means being securely mounted to said shaft in such a manner that it may be conveniently removed and replaced.
