ABSTRACT:
A space heater is operable at a low cost by a small electric motor which rotates an elongated tubular cylinder rotor member on a vertical axis, within an elongated cylindrical outer stationary member, and outwardly of an upper convection chamber member and a lower metering chamber member at a clearance of about five thirty-second of an inch in the vertical, outer and inner angular chambers formed therebetween. A supply of heavy lubricant normally occupies the lower portion of the vertical, outer and inner annular chambers and the lower metering chamber member but rises to fill the vertical, outer annular chamber and overflow the elongated tubular cylinder rotor member and return through the vertical, inner annular chambers to the lower portion during rotation of the elongated tubular cylinder rotor member; and serving for through flow of the lubricant. The elongated cylindrical outer stationary member is enclosed within a housing, having an upper plenum chamber with louver openings and a lower chamber containing an electric drive motor an an outwardly mounted electric motor and blower.
