Abstract
Abstract A barbecue grill having a grate comprised of a plurality of parallel, spaced apart slats defining minute slots therebetween the distance between edges of adjacent slats being substantially less than the width of each slat. The grate is supported above a charcoal fire and supports food thereon, whereby the food undergoes the processes of frying, broiling, grilling and smoking.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
244 words
A grate for a barbecue grill, this grate to be positioned above a radiant heat source and to support food to be cooked by the heat therefrom, the food having a frying substance associated therewith, comprising: metal support assembly means for supporting the food and for supporting a substantial portion of the frying substance in a position contiguous to the food, said support assembly means including a plurality of parallel, spaced apart slats defining a plurality of minute slots between adjacent edges thereof, a continuous ring rigidly coupled to the bottom surface of each of said slats adjacent the ends of each of said slats, and a plurality of spaced apart parallel support rods rigidly coupled to the bottom surface of each of said slats extending perpendicular to said slats and rigidly coupled at their ends to the inside periphery of said ring; said slats each having a substantially flat top surface; and said minute slots each having a width much less than one-half the width of each of said slats, thereby allowing smoke from the radiant heat source to pass upwards into contact with the food on said support assembly means and allowing only a small portion of the frying substance to pass downwards through said support assembly means where it contacts the radiant heat source and forms the smoke, said width of said minute slots being fixed in dimension by the rigid coupling of said slats to said ring and said rods.
Claim 2
Dependent Claim
244 words
A grate for a barbecue grill, this grate to be positioned above a radiant heat source and to support food to be cooked by the heat therefrom, the food having a frying substance associated therewith, comprising: metal support assembly means for supporting the food and for supporting a substantial portion of the frying substance in a position contiguous to the food, said support assembly means including a plurality of parallel, spaced apart slats defining a plurality of minute slots between adjacent edges thereof, a continuous ring rigidly coupled to the bottom surface of each of said slats adjacent the ends of each of said slats, and a plurality of spaced apart parallel support rods rigidly coupled to the bottom surface of each of said slats extending perpendicular to said slats and rigidly coupled at their ends to the inside periphery of said ring; said slats each having a substantially flat top surface; and said minute slots each having a width much less than one-half the width of each of said slats, thereby allowing smoke from the radiant heat source to pass upwards into contact with the food on said support assembly means and allowing only a small portion of the frying substance to pass downwards through said support assembly means where it contacts the radiant heat source and forms the smoke, said width of said minute slots being fixed in dimension by the rigid coupling of said slats to said ring and said rods.
Claim 3
Dependent Claim
13 words
A grate according to claim 1, wherein said slats are rectangular in cross-section.
Claim 4
Dependent Claim
28 words
A grate according to claim 1, wherein the distance between adjacent slats and the width of one of said slats are in a ratio of 1 to 48.
Claim 5
Dependent Claim
16 words
A grate according to claim 1, wherein each of said slots has a rectangular cross-sectional configuration.
Claim 6
Dependent Claim
15 words
A grate according to claim 1, wherein the top surfaces of said slats are co-planar.
Claim 7
Dependent Claim
24 words
A grate according to claim 1, wherein the grate support surface formed by the tops of all said slats is substantially a convex surface.
