Abstract: The invention provides a modular gas cooktop system comprising a gas cooktop including compartments and standardized connections for a plurality of modular gas cooking units and an adapter. The standardized connections provide the maximum gas flow rates expected for use with the modular gas cooking units and the adapter provides gas flow rates compatible with the individual gas cooking units. The adaptor automatically reduces the gas flow rate provided to a modular cooking cartridge to match the gas flow requirement of the particular cartridge. The adapter can be added to the cartridge during the manufacturing process, thereby eliminating the requirement of removing an existing orifice from the gas appliance and replacing it with a second orifice when installing the cartridge in the gas appliance. The invention further includes a method for adapting the gas flow rate available to a modular cooking cartridge in a gas appliance.

Abstract: A gas appliance includes a pair of separate manifolds which each supply gas to two burner assemblies. Each manifold includes a relatively short and straight steel tube having a central section with a generally square-shaped cross-section and end sections with generally circular-shaped cross-sections, and a pair of end plugs closing the end sections to form a sealed interior space. The end plugs and the tube are swaged together at the end sections to form a gas-tight seal. A pair of bolt-through type valves are associated with each of the manifolds to regulate flow of gas from the manifolds to the burner assemblies. The valves have inlets directly secured to the manifolds and outlets connected to the burner assemblies with burner tubes. A pair of light-weight aluminum supply tubes connect a gas inlet with the two manifolds.

Abstract: A cooking machine control system for controlling the consumption of fuel by cooking machines, including cooking machines of the type used in restaurant kitchens, such as gas/barbecue broilers, and home cooking machines such as grills, and gas flow valves usable in such cooking machine control systems. The cooking machine control system controls the flow of gas to the burners of the cooking machine to maintain the cooking surface of the cooking machine at an appropriate standby temperature when no food is being cooked, to bring the cooking surface to an appropriate cooking temperature for a predetermined period of time when food is being cooked, and then to return the cooking surface to the standby temperature. The cooking machine control system includes a first gas pipe which provides gas to each burner of the cooking machine at the standby level and a second gas pipe which in the standby mode is closed by a valve.

Abstract: A removable interlock spacer is disposed between the rear face of a control knob and the face of a control panel of a cooking device, such as a stove or a barbecue grill, to prevent the control knob from being pushed in far enough to activate the associated cooking element(s). The push-in-and-turn type switches used in such devices require that the control knob be pushed in before the switch can be moved from its off position. The interlock spacer is of sufficient thickness to prevent the control knob from being pushed in far enough to allow the switch to be moved from its off position. Thus, the cooking element cannot be activated with the interlock spacer in position. When the cooking device is to be used, the interlock spacer may be removed and the switch will operate normally. Thereafter, when cooking is complete, the interlock spacer is re-installed so that young children and the like will not inadvertently create a hazard to themselves and others.

Abstract: A grill 10 is disclosed having: a burner housing 12; a frame 14 to support the burner housing 12; work surfaces 16, 18, and 20; and a gas supply system 22. These components provide a means for relatively easily adjusting the grill 10 between a cooking configuration and a storage configuration. Work surfaces 16 and 18 are positionable between a horizontal cooking position and a vertical storage position. A work surface 20 is removably attachable to grill 10. When work surfaces 16 and 18 are in a vertical position, and the work surface 20 is removed, the burner housing 12 and work surfaces define a first smallest perimeter around the grill. This configuration is ideal for moving and storing the grill 10. Depending on how many of the working surfaces 16, 18, and 20 are in a cooking position, second, third and fourth perimeters are defined. Thus, there is provided ample working surface space with optional reduction thereof for using, moving, and storing the grill 10.

Abstract: A burn rate control valve for gas fired heaters in the form of a 1/4 turn ball valve having two flow passages through the valve member in which one flow passage is for full gas flow and the other flow passage is smaller in diameter for low gas flow in order to provide a full burn rate or a low burn rate. The two passages are dimensioned and angularly related such that the larger or full burn rate passage essentially provides unrestricted flow when aligned with related ports or piping with the smaller or low burn rate passage being angularly related to the larger passage at an angle less than 90.degree. in order to maintain a flow passageway when the ball valve member is moved to a position with the larger passage perpendicular to the associated ports. This angular relation assures that the smaller flow passage will be opened before the larger flow passage closes too much in order that the burner will not cease to operate and not provide a lower burn rate than intended.

Abstract: The fuel and air supply apparatus provides a fuel/air mixture for gas burners. The ratio of fuel to air in the mixture is adjustable and remains constant at any setting in spite of changes in air flow rate made to adjust the flame size and height. The fuel/air mixture is supplied to the burner through a venturi which, in turn, is supplied with fuel and air. The venturi is such that the amount of gas entrained into and mixed with the air is directly proportional to the air flow velocity into the venturi. Such a venturi is available form the J & P Machine and Tool Co., 22 Delawanna Avenue, Clifton, N.J. 07014. The fuel is supplied to the venturi through a zero regulator which supplies fuel in direct proportion to the demand. The combined functions of the venturi and regulator provide the fuel/air mixture as described. A suitable zero regulator is available from Maxitrol, 23555 Telegraph, Southfield, Mich. 48037, Model No. R400SZ.
