Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
Pyrolytically self-cleaning apparatus for uniformly and efficiently cooking portions of meat and bread, comprising: a first generally tubular passageway defining a first oven, said oven having disposed therein a conveyor for transporting meat portions longitudinally therethrough, and radiant energy burners located in the top wall and lower side walls of said passageway for cooking the meat portions as they travel therethrough; a second generally tubular passageway defining a second oven, said second oven being disposed parallel to said first oven and said second oven having disposed therein a conveyor for transporting bread portions longitudinally therethrough; said first oven being connected with said second oven by a longitudinally extending opening along substantially the entire length thereof, so that heat from said first oven may be readily transferred to said second oven; and, means for connecting said burners to a source of combustible gas.
Claim 2
Dependent Claim
142 words
