Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
238 words
A first two-way adjustable cooking grid comprising: a first set of parallel, spaced apart tubes perpendicularly attached to a first end tube; a second set of parallel spaced tubes perpendicularly attached to a second end tube, said first and second sets spaced apart from but parallel to each other, said second end tube having a first rod fixedly attached to its center and projecting therefrom to slidingly engage the open end of said first end tube; a third set and a fourth set of parallel, spaced apart tubes perpendicularly attached to a third and a fourth end tube, respectively, said third and fourth sets of tubes spaced opposite and coaxial with said first and said second sets of parallel, spaced apart tubes; a multiplicity of rods fixedly attached to the open ends of said third and fourth sets of parallel tubes, said rods extending from the open ends of said third and fourth sets of parallel tubes a distance, said multiplicity of rods slidingly engaging the open ends of said first and second sets of parallel, spaced apart tubes; a second rod extending from the center of said fourth end tube toward said third end tube and fixedly attached to said fourth end tube, said second rod extending therefrom a distance, said second rod slidingly engaging the open end of said third end tube; when the various rods engage their adjacent tubes, a two-way adjustable grid is formed.
Claim 2
Dependent Claim
238 words
A first two-way adjustable cooking grid comprising: a first set of parallel, spaced apart tubes perpendicularly attached to a first end tube; a second set of parallel spaced tubes perpendicularly attached to a second end tube, said first and second sets spaced apart from but parallel to each other, said second end tube having a first rod fixedly attached to its center and projecting therefrom to slidingly engage the open end of said first end tube; a third set and a fourth set of parallel, spaced apart tubes perpendicularly attached to a third and a fourth end tube, respectively, said third and fourth sets of tubes spaced opposite and coaxial with said first and said second sets of parallel, spaced apart tubes; a multiplicity of rods fixedly attached to the open ends of said third and fourth sets of parallel tubes, said rods extending from the open ends of said third and fourth sets of parallel tubes a distance, said multiplicity of rods slidingly engaging the open ends of said first and second sets of parallel, spaced apart tubes; a second rod extending from the center of said fourth end tube toward said third end tube and fixedly attached to said fourth end tube, said second rod extending therefrom a distance, said second rod slidingly engaging the open end of said third end tube; when the various rods engage their adjacent tubes, a two-way adjustable grid is formed.
Claim 3
Dependent Claim
83 words
A two-way adjustable cooking grid as defined in claim 1 comprising: a second adjustable cooking grid formed of rods and tubes similar to said first adjustable cooking grid and having ends fixedly attached to the first adjustable cooking grid, said second adjustable cooking grid being disposed in a plane parallel to the plane of said first adjustable cooking grid with the rods and tubes of said second cooking grid running at right angles to said rods and tubes of said first cooking grid.
Claim 4
Dependent Claim
24 words
A two-way adjustable cooking grid as defined in claim 1, said grid having disposed on its four corners removable legs for elevating said grid.
Claim 5
Dependent Claim
65 words
A two-way adjustable cooking grid as defined in claim 1, said cooking grid having a multiplicity of short lifting and adjusting pegs projecting outwardly at right angles from the tubes defining the periphery of said grid, said short pegs disposed in the plane of said grid, said pegs being located near the ends of said peripheral tubes, said pegs being spaced apart a predetermined distance.
Claim 6
Dependent Claim
137 words
A two-way adjustable cooking grid as defined in claim 4, said grid being provided with a pair of lifting and adjusting tongs, said tongs made in a continuous band of material in a modified keyhole shape, the top and bottom of said keyhole being flat, the sides of said tongs tapering outward to a width at the bottom which exceeds the spacing of said pegs on adjacent peripheral tubes when said grid is fully expanded, the narrowest part of said keyhole shape being less than the spacing of said pegs on said adjacent peripheral tubes when said grid is fully retracted, placing the bottom of said tongs under said pegs allows said grid to be lifted by said tongs, using the tapered sides of said tongs the spacing of said pegs on adjacent tubes can be altered.
