Abstract
Abstract Apparatus for cooking meat patties and the like including a pair of opposing heat transfer plates having inner cooking faces for holding the patties therebetween and an outer heat receptor portion for receiving heat such as from the surrounding fat in a deep-fat cooker. Securing the plates a predetermined distance apart corresponding to the thickness of the meat pattie. Adjustably connecting the plates together to compress the uncooked meat pattie and/or to compress the meat pattie as it is being cooked. Providing a stack of heat transfer plates which form a series of vertically spaced compartments, with alternate compartments being used for holding a meat pattie, and the interstitial compartments receiving the heat source medium such as fat.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
151 words
A device for cooking meat patties and the like in a deep-fat cooker, including in combination: a frame having an arm connected thereto; vertical rod means mounted on said frame; plate means carried on said rod means and comprising horizontal plate members for defining a plurality of interstitial cooking compartments to hold meat patties and vertically spaced-apart heating compartments above and below each interstitial cooking compartment to receive the hot cooking fat; actuating means coupled between said arm and said plate means to vertically enlarge each of the interstitial cooking compartments when said arm is moved to a second position and to vertically contract each of the interstitial cooking compartments when said arm is moved to a first position; and spring biasing means engaging each of the plate members for allowing the aforementioned vertical enlargement and contraction of the interstitial cooking compartments without changing the vertical spacing in the heating compartments.
Claim 2
Independent Claim
151 words
A device for cooking meat patties and the like in a deep-fat cooker, including in combination: a frame having an arm connected thereto; vertical rod means mounted on said frame; plate means carried on said rod means and comprising horizontal plate members for defining a plurality of interstitial cooking compartments to hold meat patties and vertically spaced-apart heating compartments above and below each interstitial cooking compartment to receive the hot cooking fat; actuating means coupled between said arm and said plate means to vertically enlarge each of the interstitial cooking compartments when said arm is moved to a second position and to vertically contract each of the interstitial cooking compartments when said arm is moved to a first position; and spring biasing means engaging each of the plate members for allowing the aforementioned vertical enlargement and contraction of the interstitial cooking compartments without changing the vertical spacing in the heating compartments.
Claim 3
Dependent Claim
79 words
The device of claim 1 wherein each of said plate members includes a cooking face forming a boundary for its adjacent cooking compartment and an oppositely directed heat receptor surface forming a boundary for its adjacent heating compartment, and wherein said spring biasing means includes first spacer means in the heating compartment extending between and spacing apart the heat receptor surfaces a first predetermined distance and a normally expanded spring in the cooking compartment extending between the cooking faces.
Claim 4
Dependent Claim
38 words
The device of claim 2 wherein said spring biasing means includes second spacer means in the cooking compartment extending between and spacing apart the cooking faces a second predetermined distance when said arm is in said first position.
Claim 5
Dependent Claim
29 words
The device of claim 3 wherein said first and second spacer means are differently sized to form a first predetermined distance which is different from said second predetermined distance.
Claim 6
Dependent Claim
41 words
The device of claim 1 wherein said plates are elongated, and wherein said rod means includes central rod means located intermediate of end rod means to form horizontally spaced-apart sections for holding two or more meat patties in each cooking compartment.
Claim 7
Dependent Claim
13 words
The device of claim 1 including a handle fixedly connected to said frame.
Claim 8
Dependent Claim
18 words
The device of claim 1 wherein the portion of said plates forming the cooking compartments are without perforations.
Claim 9
Independent Claim
293 words
A device for cooking meat patties and the like in a deep-fat cooker, including in combination: a frame; vertical rod means mounted on said frame; plate means carried on said rod means and comprising horizontal plate member for defining a plurality of interstitial cooking compartments to hold meat patties and vertically spaced-apart heating compartments above and below each interstitial cooking compartment to receive the hot cooking fat, each of said plate members including a cooking face forming a boundary for its adjacent cooking compartment and an oppositely directed heat receptor surface forming a boundary for its adjacent heating compartment; an arm connected to said frame said arm being shiftable from a first position to a second position; a handle on said frame fixedly connected to said vertical rod means; actuating means coupled between said arm and said plate means to vertically enlarge each of the interstitial cooking compartments when said arm is moved to a second position and to vertically contract each of the interstitial cooking compartments when said arm is moved to a first position; and spring biasing means engaging each of the plate members for allowing the aforementioned vertical enlargement and contraction of the interstitial cooking compartments without changing the vertical spacing in the heating compartments, including first spacer means in the heating compartment extending between and spacing apart the heat receptor surfaces a first predetermined distance when said arm is in both first and second positions, second spacer means in the cooking compartment extending between and spacing apart the cooking faces a second predetermined distance when said arm is in said first position, and a normally expanded spring in the cooking compartment for holding apart the cooking faces a third predetermined distance when said arm is in siad second position.
Claim 10
Independent Claim
293 words
A device for cooking meat patties and the like in a deep-fat cooker, including in combination: a frame; vertical rod means mounted on said frame; plate means carried on said rod means and comprising horizontal plate member for defining a plurality of interstitial cooking compartments to hold meat patties and vertically spaced-apart heating compartments above and below each interstitial cooking compartment to receive the hot cooking fat, each of said plate members including a cooking face forming a boundary for its adjacent cooking compartment and an oppositely directed heat receptor surface forming a boundary for its adjacent heating compartment; an arm connected to said frame said arm being shiftable from a first position to a second position; a handle on said frame fixedly connected to said vertical rod means; actuating means coupled between said arm and said plate means to vertically enlarge each of the interstitial cooking compartments when said arm is moved to a second position and to vertically contract each of the interstitial cooking compartments when said arm is moved to a first position; and spring biasing means engaging each of the plate members for allowing the aforementioned vertical enlargement and contraction of the interstitial cooking compartments without changing the vertical spacing in the heating compartments, including first spacer means in the heating compartment extending between and spacing apart the heat receptor surfaces a first predetermined distance when said arm is in both first and second positions, second spacer means in the cooking compartment extending between and spacing apart the cooking faces a second predetermined distance when said arm is in said first position, and a normally expanded spring in the cooking compartment for holding apart the cooking faces a third predetermined distance when said arm is in siad second position.
Claim 11
Dependent Claim
63 words
The device of claim 8, wherein said plate means includes a bottom plate member having downwardly extending flange means along its periphery to form a support base for the device and for spacing apart the heat receptor surface of said bottom plate from the cooker bottom a fourth predetermined distance to define a heat compartment between the cooker bottom and said bottom plate.
Claim 12
Dependent Claim
16 words
The device of claim 8 wherein said cooking faces of said plate members are without perforations.
