Abstract

Abstract Some commercial broilers have a conveyor extending through the broiler from an entrance opening to an exit opening and have a plurality of burner housings, including end burner housings, arranged above the conveyor and spaced apart with respect to each other and particularly with respect to the entrance opening and the exit opening to leave gaps. To conserve heat, the passageway through the broiler above the conveyor is herein restricted by baffles including an entrance shield of heat-reflecting material formed as a channel frictionally fitting over the entrance burner housing and having a baffle sheet extending from the entrance burner housing through most of the gap toward the entrance opening. Also included is an exit shield of similar material formed as a similar channel fitting over the exit burner housing and having a baffle sheet extending from the exit burner housing through most of the gap toward the exit opening. Further, there is an intermediate shield including a horizontal sheet of similar material resting on adjacent burner housings and having a vertical sheet depending from said horizontal sheet. The entrance shield, the exit shield and the intermediate shield define the upper limits of the passageway through the burner and tend to reflect heat away from the entrance and exit openings and to limit air circulation within and through the passageway.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 171 words
For use in a broiler having a conveyor running in a predetermined direction between an entrance opening to the broiler and an exit opening from the broiler; a plurality of burner housings above the conveyor, said burner housings having transverse, upright, side walls and a connecting, horizontal top wall; one of said burner housings being spaced in said predetermined direction from one of said openings to leave an end gap; and said burner housings being spaced apart in said predetermined direction from each other to leave a central gap between them; an array of heat reflecting baffles comprising an end shield having a top sheet and transverse, upright side sheets defining a channel adapted frictionally to engage and slide on said side walls of said housing and having a baffle sheet extending substantially in said predetermined direction across said end gap; and an intermediate shield having a horizontal sheet resting upon said burner housings and extending across said central gap, and including a vertical sheet depending centrally from said horizontal sheet.
Claim 2
Dependent Claim 171 words
For use in a broiler having a conveyor running in a predetermined direction between an entrance opening to the broiler and an exit opening from the broiler; a plurality of burner housings above the conveyor, said burner housings having transverse, upright, side walls and a connecting, horizontal top wall; one of said burner housings being spaced in said predetermined direction from one of said openings to leave an end gap; and said burner housings being spaced apart in said predetermined direction from each other to leave a central gap between them; an array of heat reflecting baffles comprising an end shield having a top sheet and transverse, upright side sheets defining a channel adapted frictionally to engage and slide on said side walls of said housing and having a baffle sheet extending substantially in said predetermined direction across said end gap; and an intermediate shield having a horizontal sheet resting upon said burner housings and extending across said central gap, and including a vertical sheet depending centrally from said horizontal sheet.
Claim 3
Dependent Claim 14 words
A device as in claim 1 in which said baffles are of heat-reflecting material.
Claim 4
Dependent Claim 32 words
A device as in claim 1 in which said end shield is inclined with respect to said conveyor in a direction to reflect heat away from an adjacent one of said openings.
Claim 5
Dependent Claim 69 words
As a sub-combination for use with a burner housing as in claim 1, wherein said baffle comprises a single sheet of heat-reflecting material bent upon itself to provide a channel shape generally rectangular in transverse cross-section and of a size frictionally engageable over said burner housing and having extending from one of the side walls of said channel a baffle sheet projecting at an angle to said side wall.
Claim 6
Dependent Claim 54 words
As a sub-combination for use between two adjacent but spaced apart burner housings having edge flanges in opposition as in claim 1, said baffle comprising a horizontal sheet of heat-reflecting material adapted to rest on said edge flanges and with a vertical sheet of heat-reflecting material depending from the center of said horizontal sheet.
