Abstract: An adjustable height grilling grate assembly includes a grate having a perimeter edge. A lift is attached to the grate for lifting or lowering the grate. The lift comprises a pair of vertical supports and a spindle is rotatably attached to and extends between each of the vertical supports. A pair of cables is attached to the spindle and are wound onto the spindle when the spindle is rotated in a first direction and unwound from the spindle when the spindle is rotated in a second direction. Each of the cables terminates with a connector and the connectors are attached to the grate. A pair of couplers is provided and each the vertical supports has one of the couplers slidably mounted thereto. The couplers engage the perimeter edge of the grate to retain the grate in a horizontal orientation when the vertical supports are in a vertical orientation.

Abstract: The specification describes a system for initiating and promoting combustion of fuels such as wood, coal, oil, etc. Virtually complete combustion is achieved by feeding combustion air under pressure through openings in a diffuser plate with the diameter of the opening having a calculated size and spacing therebetween. By-products of primary combustion are burned by the system. The specification also describes an exemplary wood stove and a cooking unit which utilizes the novel combustion principle.

Abstract: A miniaturized forge consisting of a metal body with slots and openings to admit the metal to be heated, along with a bracket for holding a separate fuel tank containing a torch which extends vertically downward through a hole in the metal body. The torch within the forge is able to selectively heat areas of metal objects to a temperature high enough to allow them to be bent into a desired shape.

Abstract: A portable gas forge. The forge is comprised of a housing having an insulated interior and an opening for insertion of the article to be heated such as a horseshoe or the like. The forge is resistant to blow-out by wind when used in the field and has a specially designed burner connected to the top of the housing. The burner is connected to a source of gas such as an LP gas cylinder. A gas orifice is connected to an enlarged burner pipe having a bell-shaped primary air inlet adjacent the gas orifice. A source of secondary air is located at the exterior pipe connection to the housing to provide an annular air passage through the housing to the burner outlet to obtain maximum flame concentration in the housing and inhibit burn back or back flaming. An internal restrictor adjacent the burner pipe outlet is employed to increase the burner gas velocity and aid in secondary air aspiration and combustion efficiency.

Abstract: Diverse ceramic briquettes, for example clay tiles, are fired in holders which are stacked on top of one another on a firing conveyor. Firing takes place in a tunnel kiln which is primarily heated with gas or oil. Firing with solid fuel has the disadvantage that the firing conveyor is heavily dirtied. With the new holder according to the invention, the holder floor is filled with solid fuel and thereafter the briquettes are put in. This holder and the method used for firing permit a clean firing without dirtying the kiln and without high dust emission.

Abstract: The present invention consists of a forge for heating horseshoes or the like to enable a blacksmith to shape and form metal objects. The forge or oven includes a gas burner which is positioned to maximize the heating capabilities of the oven while utilizing a minimum of gas fuel.
