Abstract: 14,823. Thompson, W. P., [American Incandescent Gas Co.]. July 5. Air-heating gas stoves; water-heating gas stoves.- Relates to apparatus in which air and water are heated by gas jets, the apparatus serving as a radiator, and the air or water, or both, being circulated through pipes to be used for heating other apartments. Figs. 4, 5, and 7 are vertical sections of an apparatus, the base A of which stands on india-rubber feet a, a to prevent the transmission of heat. The burner F consists of a perforated U-tube held against the gas inlets by a spring a<2>. Under the burner is a removable grating B support ing a pan C containing a reflector, in which the burner can be seen through glazed openings E, E in the base. A pilot jet burns in a perforated metal cap for the instantaneous ignition of the burner F when the gas is turned on. The water-heater and radiator consists of a number of similar flat boxlike sections J, a top section K, and a bottom section I. The bottom section tapers towards the drop-down g, which is provided with a draw-off valve h. It is connected to the lowest section J by a screwed thimble j, the two being screwed up so that their bosses abut. The sections J are divided by diaphragms n extending across and from one end to near the other, and are connected by thimbles screwed into flanged openings p. The upper section K is connected by a thimble S extending to near the top. A pipe L screwed into the upper section passes through openings in the sections J, and is screwed into the lower section and made tight by a nut and washer. The water circulates upwards through the connecting-thimbles and down through the pipe L. Pipes M, M, passing through openings in the sections K and J and resting on the bottom section over the openings m, m, convey the combustion products into an air receiver N divided by horizontal diaphragms S, S. From this receiver the air may flow out into the apartment by a regulator Y, or it may be conveyed into a heating-system by a pipe U. The compartment 0 contains a safety-device to prevent overpressure in the water-heater. Openings Z are made in one end of the receiver to admit air. Corrugated metal ribbons x<2> may be placed in the tubes M to retard the passage of the hot gases. A gas jet burns in the pipe U to induce a current in the right direction, and any vapour condensing in it is conveyed by a pipe to the pan C. In a modification, the heated water circulates through heating-pipes connected to manifolds H<1>, H<2> as shown in Fig. 8. The pipes M, M are dispensed with, and the sections I', I<1> are enclosed in a casing J through which the products ascend to the receiver L'. The sections are shortened at opposite ends alternately, so that the products pass along their upper and under sides. From the receiver L' the products pass to a chimney. It is surrounded by an air-heating chamber N' divided by a vertical diaphragm O<1> separating the circulating pipes P<1>, Q<1>. The gas supply to a number of these heaters, distributed throughout a building, may be regulated by valves in a central station.
