Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
211 words
An apparatus for successively broiling units of comestibles comprising: a broiling zone formed from oppositely positioned irradiating heating means; means for energizing said heating means; a substantially horizontal movable conveyor means, said conveyor means formed from two spaced-apart members, one of said members comprising a rotating continuous chain-link belt on edge that comes together with the other member within the broiling zone to form an elongated slot therebetween for supporting comestibles therein on both sides as the belt travels through said broiling zone and then separates from the other member after passage through said broiling zone by turning away from said member to discharge said comestibles from the conveyor after broiling, said continuous belt having an open grid surface throughout its length adapted to receive comestibles subsequent to the turning away travel by the belt and before the turning inwardly travel by the belt and support means for supporting the comestibles in a vertical position on said grid surface, a hinged elongated grid gate mounted adjacent the belt having an open grid surface and turnable from a horizontal position whereat the comestibles can be placed on to a vertical position whereat the comestibles are transferred to the open grid surface of the belt, and means to drive the continuous chain-link belt.
Claim 2
Independent Claim
211 words
An apparatus for successively broiling units of comestibles comprising: a broiling zone formed from oppositely positioned irradiating heating means; means for energizing said heating means; a substantially horizontal movable conveyor means, said conveyor means formed from two spaced-apart members, one of said members comprising a rotating continuous chain-link belt on edge that comes together with the other member within the broiling zone to form an elongated slot therebetween for supporting comestibles therein on both sides as the belt travels through said broiling zone and then separates from the other member after passage through said broiling zone by turning away from said member to discharge said comestibles from the conveyor after broiling, said continuous belt having an open grid surface throughout its length adapted to receive comestibles subsequent to the turning away travel by the belt and before the turning inwardly travel by the belt and support means for supporting the comestibles in a vertical position on said grid surface, a hinged elongated grid gate mounted adjacent the belt having an open grid surface and turnable from a horizontal position whereat the comestibles can be placed on to a vertical position whereat the comestibles are transferred to the open grid surface of the belt, and means to drive the continuous chain-link belt.
Claim 3
Dependent Claim
29 words
The apparatus of claim 1 in which said conveyor means is formed from two continuous chain-link belts on edge, one belt rotating clockwise and the other belt rotating counterclockwise.
Claim 4
Dependent Claim
14 words
The apparatus of claim 2 in which each of said belts is sprocket driven.
Claim 5
Dependent Claim
52 words
The apparatus of claim 3 in which the sprocket of at least one of the belts where the belts turn away from each other has means for extending through the chain links of the belt for pushing the comestible from it in those cases where it has seared to the chain links.
Claim 6
Dependent Claim
20 words
The apparatus of claim 4 in which said means that extend through the chain links are sprockets having elongated teeth.
Claim 7
Dependent Claim
36 words
The apparatus of claim 2 in which a comestible removal bar is operatively associated with said chain-link belts as they turn away from each other to strip any comestibles that have seared to the chain links.
Claim 8
Dependent Claim
40 words
The apparatus of claim 2 in which each of said chain-link belts is sprocket driven and one of said sprockets on each of said belts has cam means operatively associated therewith for slackening said belt for its removal for cleaning.
Claim 9
Dependent Claim
30 words
The apparatus of claim 2 in which one of the links in the chain of each of said belts is removable so that the belts can be removed for cleaning.
Claim 10
Dependent Claim
37 words
The apparatus of claim 1 further comprising guide means for maintaining said comestibles positioned on the open grid surface of the belt means in a vertical position on said belt until they travel into the broiling zone.
Claim 11
Dependent Claim
33 words
The apparatus of claim 1 in which said support means on the open grid surface of the belt comprises spaced stud supports at the bottom thereof for supporting the comestible in vertical position.
Claim 12
Dependent Claim
30 words
The apparatus of claim 1 in which said conveyor means has cleaning means operatively associated therewith for cleaning seaRed portions of comestibles from it during passage to the broiling zone.
Claim 13
Dependent Claim
29 words
The apparatus of claim 1 in which said broiling zone has positioned below it a residue trough for collecting proteinaceous juices and fats exuding from said comestibles during broiling.
Claim 14
Dependent Claim
35 words
The apparatus of claim 1 further comprising a receiving tray mounted beneath the belt and the other member at a point where the belt separates from the other member to receive the discharged broiled comestibles.
Claim 15
Dependent Claim
26 words
The apparatus of claim 1 in which said irradiating heating means has a thermostat control operatively connected thereto for controlling the temperature in the heating zone.
Claim 16
Dependent Claim
40 words
The apparatus of claim 1 in which said means for energizing said conveyor means has speed control means operatively connected thereto for varying the speed of travel of the conveyor through the broiling zone depending upon the requirements for broiling.
Claim 17
Dependent Claim
28 words
The apparatus in claim 1 in which said broiling zone has positioned above it a grill means which is heated from sensible heat rising from said broiling zone.
Claim 18
Dependent Claim
15 words
The apparatus in claim 1 in which said irradiating heating means are gas-fired ceramic plates.
Claim 19
Dependent Claim
14 words
The apparatus of claim 1 in which said irradiating heating means are electrically energized.
Claim 20
Dependent Claim
33 words
The apparatus of claim 1 in which a control means is operatively connected between said irradiating heating means and said conveyor means to deenergize the heating means when said conveyor means is inoperative.
