Application filed. Iltarch 29, 1915. I Serial No. 17,790.

To all whom it may concern:

7 Be it known that I, JOHN C. TATE, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Heaters, of which the following is a specification.

The present invention relates to improvements in heaters and more particularlyto a type of heater commonly known as gas radiators.

The invention consists in providing a structure of the radiator type with a reheating chamber on either side of the combustion chamber and which will superheat the already heated gases at a point adjacent the discharge opening, and thus cause a continuous circulation of gases in the heater.

The invention also consists in providing one or more relief valves in the heat circulation chambers to compensate for any sudden expansion of the gases when the burner .is lighted.

' The invention has for its objects to provide a heater of the above type having a large area of radiation surface, one wherein the heated air and products of combustion are discharged into a chimney instead of the room in which the heater is located, one having a clear air circulation, thus insuring proper combustion, and one provided with relief valves which admit an escape of sudden undue pressures within the heater.

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size, and minor details of construction within thescope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To more fully comprehend reference is .directed to the accompanying drawings, wherein- Figure 1 is a view in side elevation of a radiator constructed 1n accordance w1th this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a view in end elevation of a-portion of one of the sections, disclosing the reheating chamber. Fig. 4 1s a sectional view of one of the sections dis- Specification of Letters Patent.

closing the combustion chamber. Fig; 5 is a transverse sectional view taken on line 5-5 of Fig. 4. Fig. 6 is an enlarged detail of one of the relief valves in the upper portion of the heater in open position. Fig, 7 to is a vertical sectional view of the valve in Fig. 6. Fig. 8 is a transverse sectional view: taken on line 88 of Fig. 7. Fig. 9 is a top plan view of one of the relief valves at the lower portion of the heater. Fig. 10 is a as front elevation of the valve disclosed in Fig. 9, partly broken away. Fig. 11 is a vertical sectional view of the valve disclosed in Figs. 9 and 10.

Referring more particularly to the several 7o views of the drawings, wherein like characters of reference refer to corresponding parts1 designates a tubular radiator men1- ber preferably formed-vertically into two parts, the meeting edges of which are- 4 into which extends, through a suitable opening 5 a burner 6 connected to any suitable source of fuel supply. The burner is received at its inner end in a seat 7 and the fuel fiow is controlled by a suitable valve 8.

A lighting aperture 9 is formed in the wall of the member 1 above the burner, and an open portion 10 is formed in the base to admit a1r for combustion and for circulation through the radiator.

A reheating chamber 11 is formed on either side of the combustion chamber by the walls 12 which are preferably formed integral with the'walls of the member 1 and extend approximately one-half of the length of the'member 1. The chambers 11 connect as at a point adjacent their upper ends and provide an outlet 13 which is surrounded by a flange 16 projecting from the body 1, and to which a suitable stack is adapted to be attached.

the mom or 1 are formed with flanged outlet'openings 17, and the lower portion of the walls 12 are each formed with suitable inlet openings 18, and communicating with the 105 respective openings are the flanged walls 19 surrounding openings 19 in the upper and The '-u per ends of the side walls forming It will be apparent that the air entering the open portion lO and being heated by the flame from the burner will rise in the combustion chamber 4 and pass with the products of combustion outwardly through the openings 17 into the tubular circulating sections 20 through the upper openings 19. The heated gases rising in the combustion chamber 1 will cause the gases in the circulating sections 20 to pass downwardly and into the reheating chambers 11 through the openings 18, the reheating of the heated gases causing a rapid circulation of gases within the combustion chamber 1 and tubes 20, and the heated gases after passing through the reheating chamberswill pass outwardly through the stack opening 16.

It will be apparent that the heated gases passing into the reheating chambers and being again heated therein, and to a higher temperature than that in the tubes 20,- will in passing through the stack opening 13 draw the gases contained in the circulating sections 20 downwardly and thus maintain a constant circulation of heated gases within the heater.

The outer wall 21 of the circulation tubes 20 adjacent the

openings

17 and 19 are provided with suitable relief openings 22 at the upper ends and openings 23 at the lower ends, and through said openings are adapted to pass any sudden excess pressures created within the heater, such as that caused by the explosion of unconsumed gases in the combustion chamber. The openings 22, Figs. 6, 7 and 8, are normally closed by suitable covers or valves 24: which are adapted to seat against the outer surface of an annular member 25 surrounding the openings. Secured to a lug 26 projecting from the inner face of each valve 24 is the shank portion 27 of a substantially T-shaped member 28, the weight of which is sufficient to retain the valves in their closed position against their respective seats 25, and the lateral arms 29 of which contact with the interior of the circulating tubes 20 and limit the outward movement of the valves.

Surrounding the openings 23-Figs. 9, 10 and 11, are annular flange members 30 against which abut the seats 31 for the cover plates or valves 32 which are pivoted at their upper ends, as at 33, to the seats 31 and are. normally closed by gravity. The seats 31 are formed with a web 34 through which extends the rod 35 carrying the nuts 35 which retain the flanges 19 of the lower opening 19 in contact with the wall 12 surrounding the openings 18. Suitable yokes 36 connected by a rod 36' contactwith the inner surface of the walls 21 surrounding the upper openings 19 in the circulating tubes 20 and retain the flanged walls 19 thereof in contact with the wall surrounding the openings 17. Suitable supporting legs 37 are-carried by the lower ends of the circulating tubes 20 and support the heater above the floor.
