Claims
- 1. A portable heating device for use in a standard fireplace opening in conjunction with an aperture permanent damper frame of said standard fireplace, the original fireplace damper plate opened to its furthest upstanding position with the remaining portion of the original fireplace damper assembly disconnected from said original fireplace damper plate, said heating device comprising:
- (A) housing means, a portion of which forms a heating chamber having an apertured region in the upper portion of said heating chamber, said housing means incorporating means for positioning the housing within the standard fireplace opening inwardly spaced from the masonry wall thereof, said housing further incorporating an openable front portion communicating with the heating chamber for placement of fuel therein;
- (B) a closeable damper assembly movably mounted in said upper apertured portion of the heating chamber for connecting the heating chamber to the fireplace flue, said damper assembly incorporating,
- (1) an adapter plate dimensioned to cover and block a pre-existing damper opening in said permanent damper frame having a central aperture formed therein;
- (2) an aperture adapter assembly dimensioned to cover and block a portion of the central aperture of the adapter plate, comprising:
- (a) an aperture adapter frame dimensioned to contact a portion of the adapter plate, having an aperture substantially equal to and aligned with the central aperture of the adapter plate; and
- (b) an aperture adapter plate positionably mountable to the aperture adapter frame generating a second central aperture;
- (3) a damper flue conduit dimensioned to extend through said second central aperture and having:
- (a) a lower entrance portal juxtaposed to the apertured region in the upper portion of the heating chamber and
- (b) an upper exit portal opening into the fireplace flue;
- (4) a damper plate movably mounted to said housing means at the upper portion of said housing means; and
- (5) means for manually positioning said damper plate; and
- (C) means for admitting air into the heating chamber;
- whereby an air convection space is created between the outer portion of the enclosed heating chamber and the masonry fireplace wall so that air entering the convection space is circulated back past the housing and outside the fireplace for space heating purposes.
- 2. The portable heating device defined in claim 1, wherein the aperture adapter assembly and the adapter plate are positioned and held beneath the damper frame by telescoping support means extending from the masonry floor of a standard fireplace to the lower surface of the aperture adapter assembly, and positioned near the two sidewalls of the standard fireplace so as to secure the aperture adapter assembly and plate to the existing damper frame while allowing the self-contained heating device to be readily installed and removed from the standard fireplace.
- 3. The portable heating device defined in claim 2, wherein said telescoping support means comprises a pair of telescoping slotted T-members.
- 4. The portable heating device defined in claim 1 wherein the damper plate is of a smaller cross-sectional area than the damper flue conduit, thereby preventing smoke buildup within the portable heating device even when the damper plate is in the fully closed position.
- 5. A portable heating device as defined in claim 1, wherein the openable front portion of the housing means incorporates pivotal glass doors which may be opened to supply fuel to the heating chamber and closed to prevent escape of soot, ashes and smoke.
- 6. A portable heating device as defined in claim 5, wherein the glass doors are removably pivotally supported by the housing means.
- 7. A portable heating device as defined in claim 6, wherein each glass door is pivotally secured to the housing by a coaxial pair of pivot pins.
- 8. A portable heating device as defined in claim 1, wherein the openable front portion of the housing means incorporates pivotally mounted metal doors which may be opened to supply fuel to the heating chamber and closed to prevent the escape of soot, ashes and smoke, said doors incorporating a substantially flat grillwork spaced therefrom for providing further air convection by the heating device.
- 9. A portable heating device as defined in claim 1, wherein the housing means inorporates an outer framework spaced from and substantially surrounding said heating chamber, a frontal screen interconnected with the inner periphery of said outer framework, and a portal fascia interconnected at its outer periphery with the frontal screen and at its inner periphery with the heating chamber.
- 10. A portable heating device as defined in claim 1 wherein the aperture adapter plate of the adapter assembly has a pair of parallel slots, and wherein said aperture adapter assembly incorporates a pair of bolts passing through said slots into said aperture adapter frame so as to allow sliding linear positioning of the aperture adapter plate with respect to the adapter frame.
