Abstract

Abstract An electric broiler for hamburgers and the like has a supporting frame on which an endless bar conveyor is arranged to advance longitudinally with the conveyor upper run and the conveyor lower run in generally horizontal planes. A set of upper electric heating rods extends longitudinally and transversely of the frame above the upper run, and a set of lower electric heating rods extends horizontally and transversely of the frame below the lower run. Below the lower heating rods on the frame are longitudinally extending radiation baffle boxes generally rectangular in cross-section and arranged with their diagonals substantially vertical and spaced apart transversely to allow drippings to pass between them. There are radiation reflecting dihedral plates extending horizontally and longitudinally on the frame above the upper rods, the dihedral plates being supplemented by top plates supported by the dihedral plates but being largely spaced above the dihedral plates to provide dead air spaces.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 121 words
An electric broiler comprising a frame, an endless bar conveyor having an upper run and a lower run, means on said frame for supporting said upper run and said lower run in horizontal planes, upper electric heating rods, means on said frame for supporting said upper rods in a horizontal plane above said upper run, lower electric heating rods, means on said frame for supporting said lower rods in a horizontal plane below said lower run, means on said frame below said lower rods for baffling downward radiation, said baffling means including a plurality of spaced apart, hollow boxes, and means on said frame above said upper rods for reflecting upward radiation, said reflecting means including a plurality of dihedral plates.
Claim 2
Dependent Claim 121 words
An electric broiler comprising a frame, an endless bar conveyor having an upper run and a lower run, means on said frame for supporting said upper run and said lower run in horizontal planes, upper electric heating rods, means on said frame for supporting said upper rods in a horizontal plane above said upper run, lower electric heating rods, means on said frame for supporting said lower rods in a horizontal plane below said lower run, means on said frame below said lower rods for baffling downward radiation, said baffling means including a plurality of spaced apart, hollow boxes, and means on said frame above said upper rods for reflecting upward radiation, said reflecting means including a plurality of dihedral plates.
Claim 3
Dependent Claim 33 words
A device as in claim 1 in which said runs advance longitudinally of said frame, said rods extend transversely of said frame, and said boxes are elongated and extend longitudinally of said frame.
Claim 4
Dependent Claim 28 words
A device as in claim 1 including a sub-frame, means for securing said boxes to said sub-frame, and means for slidably mounting said sub-frame on said main frame.
Claim 5
Dependent Claim 23 words
A device as in claim 1 in which said boxes are rectangular in cross-section and are disposed with a diagonal thereof substantially vertical.
Claim 6
Dependent Claim 15 words
A device as in claim 4 in which said boxes are of bright, reflecting metal.
Claim 7
Dependent Claim 16 words
A device as in claim 1 in which said dihedral plates are of bright, reflecting metal.
Claim 8
Dependent Claim 18 words
A device as in claim 1 in which said plates have their ridges extending longitudinally of the frame.
Claim 9
Dependent Claim 29 words
A device as in claim 1 including top plates peripherally engaging said dihedral plates and centrally spaced from said dihedral plates at least partially to enclose dead air spaces.
