Abstract
Abstract An apparatus for supporting a fireback without the need for additional support from a wall or other structure. The apparatus consists of two support bases, each with a flat upper surface including two buttresses separated by a gap, arising perpendicularly therefrom. The fireback is placed in the gap between the buttresses and held ajar in a generally upright position. The invention includes insertable wedges which permit the varying of the gap, and therefore the angle of incidence of the fireback relative to the vertical plane. The invention maximizes the full depth of the fireplace, as well as the light reflection, heat radiation, and ornamental qualities of the fireback.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
113 words
A holder for supporting a fireback in a fireplace having a forward sloping rear wall, comprising: at least two generally longitudinal support bases, each having an upper surface, each of said support bases further including: a first buttress extending vertically perpendicular from said upper surface; and a second buttress extending vertically perpendicular from said surface and spaced from said first buttress, and forming a gap therebetween; an aperture in the upper surface of each of said support bases in the region of said gap; and insertable metal wedges adapted to mate within said apertures between said buttresses thereby allowing the narrowing of said gap for restraining a fireback in a generally upright position.
Claim 2
Dependent Claim
113 words
A holder for supporting a fireback in a fireplace having a forward sloping rear wall, comprising: at least two generally longitudinal support bases, each having an upper surface, each of said support bases further including: a first buttress extending vertically perpendicular from said upper surface; and a second buttress extending vertically perpendicular from said surface and spaced from said first buttress, and forming a gap therebetween; an aperture in the upper surface of each of said support bases in the region of said gap; and insertable metal wedges adapted to mate within said apertures between said buttresses thereby allowing the narrowing of said gap for restraining a fireback in a generally upright position.
Claim 3
Dependent Claim
42 words
The holder for supporting a fireback as recited in claim 1 in which: said buttresses are of sufficient height with respect to said upper surface to maintain the fireback in a generally upright position when said fireback is disposed within said gap.
Claim 4
Dependent Claim
37 words
A holder for supporting a fireback as recited in claim 1 in which each of said support bases further comprises: at least one hole in said upper surface thereof to accommodate the legs of an andiron therein.
Claim 5
Dependent Claim
144 words
In a fireplace having a shallow depth and a substantially forward sloping rear wall, a fireback, and a pair of andirons, the improvement in combination therewith comprising: a pair of parallel bases for supporting said fireback against said rear wall in a substantially upright position, each of said bases including an upper surface, first and second buttresses protruding upwardly from said upper surface spaced apart thereby defining a transverse gap within which said fireback is positioned relative to said rear wall, a first hole in said upper surface within said gap, and at least one other hole in said upper surface adapted to receive a respective one of said pair of andirons; and wedge means adapted to be mounted within said gap for adjusting the position of said fireback relative to said rear wall and thereby utilizing a maximum portion of said shallow depth.
Claim 6
Dependent Claim
144 words
In a fireplace having a shallow depth and a substantially forward sloping rear wall, a fireback, and a pair of andirons, the improvement in combination therewith comprising: a pair of parallel bases for supporting said fireback against said rear wall in a substantially upright position, each of said bases including an upper surface, first and second buttresses protruding upwardly from said upper surface spaced apart thereby defining a transverse gap within which said fireback is positioned relative to said rear wall, a first hole in said upper surface within said gap, and at least one other hole in said upper surface adapted to receive a respective one of said pair of andirons; and wedge means adapted to be mounted within said gap for adjusting the position of said fireback relative to said rear wall and thereby utilizing a maximum portion of said shallow depth.
