Abstract
Abstract A top grill converter for a conventional outdoor electric or gas-fired grill is disclosed. The converter is a cartridge having side, front and back walls, a foraminous floor and a roof-forming undulated heat shield. Contained within the cartridge are preferentially regulated heating elements and heat transferring rocks. Means are provided for suspending the cartridge inside the lid of a conventional outdoor cooker and other means are shown for holding the cartridge level within the lid when the lid is raised and lowered. In use, food will be placed on a grill and the converter will be lowered over the food to cook it. Because the flame is above the food, grease and liquid secretions from the food will not catch on fire and "flare-ups" are eliminated.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
167 words
A top grill converter for a conventional outdoor electric or gas-fired grill comprising: (a) a generally parallelpipedal cartridge having a foraminous floor; (b) a back wall, front wall and side walls attached along bases of said walls to said foraminous floor, said walls being of a sufficient height to provide containment for heat transferring bricks intended to rest on said foraminous floor; (c) a roof-forming, undulated heat shield attached to said walls along the uppermost edges of said walls, said undulations paralleling the longitudinal axis of said cartridge, and said undualted heat shield's troughs being located proximate the top of said walls, and said undulated heat shield's peaks providing space and protection for heating elements; (d) heating elements located longitudinally inside said parallelpipedal cartridge under said heat shield in spaces created by said undulated heat shield's peaks, one end each of said heating elements attached to an exterior heat source; and, (e) means for suspending said cartridge beneath and inside a lid of said conventional outdoor grill.
Claim 2
Dependent Claim
167 words
A top grill converter for a conventional outdoor electric or gas-fired grill comprising: (a) a generally parallelpipedal cartridge having a foraminous floor; (b) a back wall, front wall and side walls attached along bases of said walls to said foraminous floor, said walls being of a sufficient height to provide containment for heat transferring bricks intended to rest on said foraminous floor; (c) a roof-forming, undulated heat shield attached to said walls along the uppermost edges of said walls, said undulations paralleling the longitudinal axis of said cartridge, and said undualted heat shield's troughs being located proximate the top of said walls, and said undulated heat shield's peaks providing space and protection for heating elements; (d) heating elements located longitudinally inside said parallelpipedal cartridge under said heat shield in spaces created by said undulated heat shield's peaks, one end each of said heating elements attached to an exterior heat source; and, (e) means for suspending said cartridge beneath and inside a lid of said conventional outdoor grill.
Claim 3
Dependent Claim
54 words
The cartridge according to claim 1 wherein said means for suspending said cartridge from said lid comprises a removable assembly, at least one on each side, including a hook/bolt demountably attached at its bolt end into said lid, bill of said hook/bolt placed in an aperture in short side wall of said parallelpipedal cartridge.
Claim 4
Dependent Claim
31 words
The cartridge according to claim 1 wherein said heat shield's peaks include apertures for the release of heat to allow for expansion of said heat shield during operation of said cartridge.
Claim 5
Dependent Claim
39 words
The cartridge according to claim 1 wherein said means for suspending said cartridge from said lid in a permanent installation includes a set of bolts fixed through said heat shield into said lid proximate four corners of said cartridge.
Claim 6
Dependent Claim
40 words
The cartridge according to claim 1 wherein said cartridge includes, additionally, a longitudinal foraminous wall between heat element adjacent to back wall and said other heat elements and touching said foraminous floor and said heat shield on opposing lengthwise edges.
Claim 7
Dependent Claim
60 words
The cartridge according to claim 1 wherein said cartridge includes, additionally, as a latching means on said back wall, a positioning ratchet, said ratchet sliding through and being caught by said rack of said ratchet in a slot in said lid, whereby when said lid is raised to varying heights,, said cartridge may be held parallel to a cooking grid.
Claim 8
Dependent Claim
41 words
The cartridge according to claim 1 wherein said longitudinally placed heating elements are unevenly spaced within said cartridge, said heat elements closest to front wall being more closely aligned to each other than to said element adjacent to said back wall.
Claim 9
Dependent Claim

The cartridge according to claim 1 wherein said undulations form three peaks, said peaks forming a cover for three longitudinally placed heating elements.
Claim 10
Dependent Claim
32 words
The cartridge according to claim 9 including means for preferentially regulating said heating elements, whereby when only warming is desired, the two elements closest to said front wall may be turned off.
Claim 11
Dependent Claim
65 words
The cartridge according to claim 1 wherein said means for suspending said cartridge from said lid comprises a removable assembly, one on each side, including a hook/bolt demountably attached at its bolt end into said lid, bill of said hook/bolt hooking on a detent on short side of said parallelpipedal cartridge, said detent located between front edge and horizontal midpoint of said short side wall.
Claim 12
Dependent Claim
15 words
The cartridge according to claim 10 wherein said detent on side wall is a knob.
