Abstract
Abstract A double-sided fireplace including a combustible material burning open cavity on one side and an electric resistance heater or gas fired heater on the other side. The combustible material burning cavity is designed to receive solid fuel to be burned and includes an upper portion defining an outlet for smoke and adapted for communication with the lower end of an upstanding smoke plenum or pipe. The electrical resistance heater or gas fired heater cavity also opens outwardly of the fireplace structure but is considerably more shallow than the solid combustible material burning cavity. Also, the entire body of the fireplace assembly is supported from a pedestal for rotation about an upstanding axis, whereby either side of the fireplace assembly may be faced in a given direction. Still further, the fireplace assembly is illustrated and described hereinafter in two forms, a first form comprising a conventional fireplace mounted form and the second form comprising a free standing fireplace assembly.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
232 words
In combination, a fireplace defining a hollow housing including a bottom wall, upstanding peripheral side wall portions projecting upwardly from said bottom wall and an upper smoke outlet opening defining an upper closure portion interconnecting the upper portions of said peripheral side wall portions, an upstanding transverse partition in said housing dividing the interior of the latter into front and rear chambers, solid combustible fuel support means in said front chamber and supplemental heating means disposed in said rear chamber, said side wall portions including front and rear openings opening into said front and rear chambers, a base, said housing being supported from said base for rotation relative thereto about an upstanding axis, an upper upstanding smoke pipe, and rotary coupling means rotatably connecting said smoke outlet opening to the lower end of said smoke pipe for rotation of the latter relative to the former about a second upstanding axis coinciding with the first mentioned axis, said partition isolating said rear chamber from said smoke outlet opening, said supplemental heating means comprising an electrical resistance heater, said base and housing including coacting brush and contact means operative to establish a rotatable electrical connection between said base and housing for said electrical resistance heater, said brush and contact means including means operating to automatically interrupt said electrical connection when saiD housing opening is rotated to a predetermined angular position relative to said base.
Claim 2
Dependent Claim

In combination, a fireplace defining a hollow housing including a bottom wall, upstanding peripheral side wall portions projecting upwardly from said bottom wall and an upper smoke outlet opening defining an upper closure portion interconnecting the upper portions of said peripheral side wall portions, an upstanding transverse partition in said housing dividing the interior of the latter into front and rear chambers, solid combustible fuel support means in said front chamber and supplemental heating means disposed in said rear chamber, said side wall portions including front and rear openings opening into said front and rear chambers, a base, said housing being supported from said base for rotation relative thereto about an upstanding axis, an upper upstanding smoke pipe, and rotary coupling means rotatably connecting said smoke outlet opening to the lower end of said smoke pipe for rotation of the latter relative to the former about a second upstanding axis coinciding with the first mentioned axis, said partition isolating said rear chamber from said smoke outlet opening, said supplemental heating means comprising an electrical resistance heater, said base and housing including coacting brush and contact means operative to establish a rotatable electrical connection between said base and housing for said electrical resistance heater, said brush and contact means including means operating to automatically interrupt said electrical connection when saiD housing opening is rotated to a predetermined angular position relative to said base.
Claim 3
Dependent Claim
25 words
The combination of claim 1 including motor means drivingly connected between said base and housing operable to selectively rotate said housing relative to said base.
Claim 4
Dependent Claim
107 words
The combination of claim 1 wherein said housing side wall portions in which said front and rear openings are formed are generally parallel and disposed normal to radii of said axes, a permanent wall structure having a fireplace opening formed therein, said base and housing being recessed behind said wall with said housing registered with said fireplace opening, and resilient heat resistant frame-like seal means carried by and extending about said front and rear openings and alternately engageable with the portions of said permanent wall structure defining said fireplace opening when said housing is rotated to alternately register said front and rear openings with said fireplace opening.
Claim 5
Dependent Claim
30 words
The combination of claim 1 including vertically spaced large and small diameter combined thrust and journal bearings, rotatably supporting said housing from said base for rotation about said upstanding axis.
