Abstract: The present invention provides a barbecue grill assembly comprising an upper assembly and a lower assembly, the upper assembly adapted to receive a cooking chamber. The grill assembly further comprises at least one projection on one of either the lower assembly or the upper assembly, and at least one receiver on the other of said lower assembly or said upper assembly. The projection and the receiver are cooperatively dimensioned such that the projection is received by the receiver. The projection having a first portion and a second portion wherein the first portion is adapted to be biased into contact with an inner surface of the receiver. The barbecue grill assembly includes a lateral assembly, positioned proximate the upper assembly. The lateral assembly is adapted to receive an auxiliary work surface or a cooking burner. The upper, lower, and lateral assemblies are each formed from a plurality of tubular frame members.

Abstract: A connecting structure of a blast furnace hot stove of the type in which a heat accumulation chamber dome and a combustion chamber dome are directly connected to each other through a dome connecting pipe which does not have any expansion joint. The ratio (RD/TD) of the diameter (RD) of the dome connecting pipe to the diameter (TD) of the heat accumulation chamber dome approximately meets the condition wherein 0.24.ltoreq.(RD/TD).ltoreq.0.60, while the ratio (RD/ND) of the diameter (RD) of the dome connecting pipe to the diameter (ND) of the combustion chamber dome approximately meets the condition wherein 0.44.ltoreq.(RD/ND).ltoreq.0.80. The connecting structure may have a reinforcement ring provided on straight barrel portions immediately under the heat accumulation chamber dome and the combustion chamber dome, and a connecting beam may be fixed at one end to one of the reinforcement rings and engage at its other end with the other of the reinforcement rings for limited sliding motion.

Abstract: Element structures are assembled from separately formed modular elements. Incorporated in the modular elements are stressing members, for example, connecting rods or the like, which can be aligned when the modular elements are positioned for installation. The adjacent connecting rods are secured to a coupling by means of which the rods can be tensioned and the entire assembly braced and rigidified. Tensile or compressive forces, due to elongation and shrinkage, are transmitted to and absorbed by the stressing members. The separate modular elements can be easily assembled or disassembled. The element structure has numerous uses, for example, in prefabricated wall or ceiling construction, in the manufacture of tiled stoves, and the like.

Abstract: An improved heating apparatus, for example for use as a wood or coal burning parlor stove and providing a significant heat output, has a construction for reducing thermally induced mechanical stress and for enabling the interior baffle assembly components of the apparatus to be removed therefrom, for replacement if necessary, without dismantling the apparatus exterior frame. The elements of the interior baffle assembly are interconnecting and are secured in a mechanically stable configuration by single point connection to the apparatus frame. The apparatus can have primary and secondary combustion chambers and a baffle system for directing flue gases along a circuitous path from the secondary combustion chamber to an exit aperture whereby a significant proportion of the heat of said gases is given up to the apparatus. A vertically oriented downwardly directed two component baffle separates the combustion chambers.

Abstract: A ceramic stove that may be supplied in kit form includes a base frame, a cast iron firebox secured on the base frame, a top frame attached to and surrounding the top of the firebox, and ceramic panels extending between and held by the frames in spaced relation from the firebox. The ceramic panels are "ship-lapped" relative to each other and are not cemented or otherwise positively attached to each other. Logs may be fed as fuel into the firebox door from one side of the stove allowing longer logs to be burned. The logs rest on a grate which includes a "shakable" portion for shaking ashes onto an ash pan located below the grate. A separate, small door into the firebox is provided for starting the fire and that door is covered by another, safety door which also closes the space through which the ash pan is removed for emptying. An outer screen gate is provided to overlie the firebox doors and the entire side of the firebox.

Abstract: The ceramic shell of a stove encloses a firing chamber and a helical flue gas passage and is composed of superimposed blocks, each of which has the same cross-sectional shape as the corresponding height portion of the shell. The bottom block consists of a bottom tub. The uppermost block consists of a cover provided with a smoke outlet for connection to a smoke pipe. The intermediate blocks comprise at least one set of blocks which are substantially identical in shape. In order to facilitate the building of the stove and to ensure an improved utilization of the heat of the flue gases, each of the blocks has in each end face confronting an adjacent block an annular groove, which is covered by the adjacent block and contains a refractory sealing cord, which seals the joint between said adjacent blocks. The firing chamber is surrounded by a refractory insert structure, which is disposed within the blocks that surround the firing chamber.

Abstract: A space heating wood burning stove, formed as a rectangular fire box, having a plurality of horizontal flue ducts leading to a flue manifold, adapted to generate substantial vertical convection currents of air, and further including vertical fins to enhance said convection currents, and further including a plurality of draft valves in substantial alignment with respective ones of said flue ducts for efficient burning of wood within said fire box. Assembly of the fire box of the stove is completed under stressed conditions to prevent warping of the fire box panels from heating and cooling cycles.

Abstract: An improved combustion chamber comprises a shell having a circular array of integral teeth formed at one end thereof. Shrunkfit onto said shell end at or near the roots of the teeth is a ring. The toothed end of the shell is received in an opening in a sheet header so that the ring engages against the header sheet and a continuous weld bead is formed between the ring and the header sheet all around the shell. The shell teeth are bent radially outward and engage the header sheet on the opposite side thereof from the ring so as to be in intimate thermal heat exchange contact with the sheet and these teeth are also welded to the header sheet. The aforesaid engagement between the chamber and rear head minimizes stresses on hot end of the chamber and prolong its useful life. Means engaged around the opposite end of the shell supports, and yet permits lengthwise movement of, that end of the shell.
