GAS HEATER Hart, Los Angeles, Calif. Application June 1, 1936, Serial No. 82,681 7 Claims. (Cl. 126—8'5) My invention relates more particularly to a type of gas heater which can be used as a port able heater and moved from place to place, or which can be permanently connected with the 5 gas supply in a room, and which stands above the floor in the manner of a stand lamp and so constructed and arranged that it develops a cir culating heat current and also a radiated heat directed downwardly and outwardly toward the 10 ?oor area surrounding the heater. Amongother objects of my invention are: to provide in a gas heater of the character referred to, an improved burner, preferably in sections and related so as to function as a circular burner unit, yet composed of a plurality of sections each of which receives its supply of gas and air and mixes it for combustion at the discharge outlet of the burner; to provide in connection with a gas H burner an overhanging heat radiating element of (20 refractory material of the radiant type and adapted to be heated by the combustion of the gas mixture thereunder whereby to cause a de? nite radiation of heat downwardly and outwardly from said element or elements; to provide in a £25 gas heater of the type referred to a construction and arrangement of hood or body which is kept cool around its outer surface, thus reducing any danger to a minimum and preventing possibility of ?re from contact of ?ammable material there L30 with; to provide in combination with a gas burner or heater of the character referred to an im proved thermostatic control for regulating the gas supply to the burner according to a pre determined temperature which it is desired to 35 maintain; to provide a gas heater of the char acter referred to having a supporting base casting of such weight relative to the top and body there of that there is little or no chance of its being overturned from accidental contact therewith; to 40 provide a construction and arrangement which permits of its being disassembled into small com pass for packing and shipping; and, in general, to provide an improved gas heater of the char acter referred to which is practical, ei?cient, 45 economical and ornamental. In order to fully explain my invention, I have illustrated one practical embodiment thereof on Figure 4 is a plan view looking down on the base or feet and the thermostat control, taken on line 4—4 of Fig. 1. Referring now in detail to the drawing, I have shown a base casting 5, having the legs or feet, 5 6, S, the top socket ‘I, and the dial supporting parts, 8, 8, with a dial 9 supported therein, with a revoluble dial indicator Ill, on the upper end of a rod I I, threaded at its lower end through a bracket-like member I2, forming a part of a ‘ thermostat, designated as a whole T. Said thermostat T includes a casting I3, se cured up under the base casting 5, with small screws, as at I4, and having therein two gas passages I5 and I6, leading to and from a cham 15 ber I'I, formed by a diaphragm I8, provided in its center with a diaphragm gasket I9 positioned and adapted to close the passage I5 to said cham ber H’, as shown. Supported immediately be neath said diaphragm I8 and adapted to engage and move it is a thermostat wafer 20, attached at its under side to a lever 2 I, pivotally supported at 22 in the casting or bracket I2, with the outer end of said lever 2| positioned under the end of said threaded rod II, as shown. A sheet metal housing 23 encloses the parts of said thermo stat, as indicated, said housing having the vent openings 23' around its lower end for tempera. ture influence of the thermostat wafer. A gas supply pipe 24 connects with the gas passage I5, and this pipe 24 can be either pipe or hose, as desired. Screwed into the thermostat casting I 3, is a vertical pipe 25, jointed at 26, to permit its being taken apart. This pipe communicates with the gas passage I 6 in the casting I3, as indicated. A tubular shield 21 is placed down over the pipe 25 and seated in the socket l in the base casting 5, as shown. The upper end of the tubular shield 2‘! has seated thereon a cap 28, with opening therethrough for the gas pipe 25, and it also is formed to receive the lower end of an upper tu bular shield 29, as indicated. Into the upper end of the tubular shield 29 is ?tted a tapering collar 38, screwed on the upper end of the pipe 25, and operating to force the tubular shields 2'! and 29 the accompanying sheet of drawing, which I will into rigid relationship with each other and with the base casting I6, and giving rigidity to the now describe: supporting structure and the base. Figure 1 is a vertical sectional view taken through a gas heater embodying my invention; Placed over the upper end of the gas pipe 25, is a cup-like casting 3 I, ?tting down over the col Figure 2 is a bottom plan view, with parts broken away, taken on line 2—2, of Fig. 1; Figure 3 is a fragmentary sectional view taken 55 on line 3—3 of Fig. 1; and lar 30, and having formed thereon three support ing arms, 32, 32, 32, for supporting the re?ector 50 ' 33, and the outer shade or ornamental body 34, said re?ector 33 and outer shade being separated 2 2,130,086 by a spacing clip 35, ?tted down upon the up turned bead-like edges of said re?ector and shade, and held in place by a screw bolt 35 up through the outer ends of the arms 32. Screwed down upon the top of the casting 3!, is a triangular casting 3?, having its center open to receive the tapered screw end of the gas pipe 25, and having gas passageways extending 3i’ outwardly through its three arm portions, as 10 seen in Fig. 2, and also in Fig. 1. The outer ends of said arm portions are shown upturned or pro vided with jet nozzles, as at 38, and are formed to receive each a burner section 39, held in place . thereon by small screws 42?}. The burner is really three burners, or burner sections, in one unit, with three separate Venturi tubes 3Q, each re ceiving the gas jet at 38, and having in its upper part a projecting ba?ie lip 39' in its head por tion, designated 4!. The upper end of each head. portion 63! is provided with transverse discharge slots 132, at which the combustion takes place around the full circle of the three burner bodies, as shown. ' - Supported by means of small, brackets, 43, to 25 the inner middle part of the re?ector 33, is a hollow shell-like structure 44, providing air space , insulation above the burner. Suspended under this shell member M, by a bolt 45, is a supporting member 4-6, having its outer edge formed to sup port the lower ends of radiant elements 47, the upper ends or edges of which are supported by means of struck-out lips 48, around the outer edge of the lower member of the shell 44. Said' radiant elements are of segmental form and when 35 placed together form a conical surface with the usual small projections 41’ on their overhanging surfaces. Supported around the burner head 4|, upon the arms 32, is a wire screen 49, for 40 on its side, it is not a fire hazard for the reason that the burner is of the Bunsen type, is fastened securely and will remain burning evenly. By providing the large hole through the center of the sectional burner and enough distance be is not subject to the radiated heat, but is posi tioned where the cool air is always more noticeable near the floor and where it will function more effectively to regulate the temperature of the room according to the desire of those using it and it can be set to function automatically to maintain a predetermined temperature. -I am aware that changes in the general con struction and - arrangement of my improved heater can be made without departing from the spirit thereof, and I do not, therefore limit my invention to the embodiment thereof shown and described, except as I may be limited by the hereto appended claims. I claim: , base, a gas supply pipe having its lower end an chored in said base and standing upright like a stand lamp, a gas burner mounted on the upper end of said pipe, a heat radiating member of 30 inverted'conical form supported by said pipe centrally above said burner and adjacent there to, whereby to be directly heated thereby, and a surrounding shade supported by said pipe at its upper end around said burner for re?ecting 85 radiated heat from said radiating member. safety against any falling part and for protecting the open ?amefrom children. lamp, a gas burner mounted on the upper end ' I have worked out a construction and arrange ment of the several parts of my heater so as to get the proper amount of heat radiated down 45 wardly and outwardly and the proper amount of heat going up through the heater andcreat ing a circulating current of heat, and also the re?ected heat from the reflector. Consequently my heater can be placed near furniture, close 50 to a wall or even against lace curtains without any danger therefrom. The screen 49, not only serves as a protection from the possibility of any of the radiant elements falling out of place, and as a protection to prevent children getting to 55 the ?ame, but the screen is an important factor in preventing too much heat being radiated downwardly. The reflector 33, which is preferably made of aluminum, is placed at just the proper angle to 60 reflect the heat outwardly in. all directions and to the body of a person sitting close to the heater, thus making for comfort. The outer shade or body 34 is so placed with an inch or more space for air between it and the re?ector 33, that said 65 outer shade 34 is always cool. The insulating shell 44 above the burner and the radiant seg ments prevents too much heat from passing up ward through the center of the heater, and al though a curtain or other article might be 70 blown over the top of the heater, it will not be burned or damaged. The base casting structure is suf?ciently heavy relative togthe top part of the heater that it will right itself even though it be tilted to an angle 75 of 25 degreesyand even though knocked over 25 1.
