Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
172 words
For use with a stove generally of box shape having a bottom lined with a layer of fire resistant material, a plurality of vertical sides, a top, and a plurality of legs supporting the stove with its bottom spaced above a floor surface, heat shielding and air circulating attachment means comprising first panel means adapted for ready attachment beneath the bottom of said stove and having a substantially horizontal plate portion and a plurality of substantially vertical side portions extending upwardly from said plate portion, said plate portion and side portions having means adapted to accommodate the legs of the stove whereby said first panel means is readily attachable beneath the bottom of the stove with the upper edges of said vertical side portions adjacent the bottom so as to form a substantially horizontal air passageway between the bottom and said horizontal plate portion, said vertical side portions including a plurality of apertures through which air enters said passageway to cool the bottom of the stove and shield the floor surface underneath.
Claim 2
Dependent Claim
172 words
For use with a stove generally of box shape having a bottom lined with a layer of fire resistant material, a plurality of vertical sides, a top, and a plurality of legs supporting the stove with its bottom spaced above a floor surface, heat shielding and air circulating attachment means comprising first panel means adapted for ready attachment beneath the bottom of said stove and having a substantially horizontal plate portion and a plurality of substantially vertical side portions extending upwardly from said plate portion, said plate portion and side portions having means adapted to accommodate the legs of the stove whereby said first panel means is readily attachable beneath the bottom of the stove with the upper edges of said vertical side portions adjacent the bottom so as to form a substantially horizontal air passageway between the bottom and said horizontal plate portion, said vertical side portions including a plurality of apertures through which air enters said passageway to cool the bottom of the stove and shield the floor surface underneath.
Claim 3
Dependent Claim
74 words
The heat shielding and air circulating attachment means of claim 1 comprising second panel means adapted for ready attachment to one of the vertical sides of the stove to form a vertical passageway therewith, said first and second panel means being constructed so that said horizontal and vertical passageways communicate with each other whereby air entering said horizontal passageway through said apertures passes upwardly through said vertical passageway into the space surrounding the stove.
Claim 4
Dependent Claim
25 words
The attachment means according to claim 2 wherein said vertical passageway has a cross-sectional area substantially equal to the cross-sectional area of said horizontal passageway.
Claim 5
Dependent Claim
30 words
The attachment means according to claim 2 wherein said vertical passageway terminates at its upper end with an opening at substantially the vertical level of said top of said stove.
Claim 6
Dependent Claim
15 words
The attachment means according to claim 2 having adjustable damper means within said vertical passageway.
Claim 7
Dependent Claim
43 words
The attachment means according to claim 2 having a plate pivotally mounted at the upper end of said vertical passageway and adjustable both to deflect air emerging from said vertical passageway and to control the amount of air emerging from said vertical passageway.
Claim 8
Dependent Claim
20 words
The attachment means according to claim 1 wherein said first panel means includes an aperture in said horizontal plate portion.
Claim 9
Dependent Claim
24 words
The attachment means according to claim 7 comprising adjustable gate means connected to said first panel means for adjusting air flow through said aperture.
Claim 10
Dependent Claim
36 words
The attachment means according to claim 7 having a vertically-extending lip surrounding said aperture in the bottom of said horizontally-extending passageway to prevent water atop portions of said first panel means from flowing through said aperture.
Claim 11
Dependent Claim
23 words
The attachment means defined in claim 1 wherein said first panel means is adapted to be fastened to the legs of the stove.
Claim 12
Dependent Claim
16 words
The attachment means defined in claim 1 wherein said first panel means forms a water-tight trough.
