GAS-HEATED STEAM RADIATOR.

Application filed May 10, 1927. Serial No..190,308.

The present invention is concerned with therprovision of a radiator in which gas is used as a heating medium. Part of the heat generated by the gas acts directly on the exterior walls of the radiator and part of the heat generated is transferred through the interior walls of the radiator to abody of w ter completely surrounding the burner chamber Steam is thus generated on the interior. of the radiator and an exceedingly eflicientheater is provided dueto the combined heat action of the steam andgas.

One feature of the invention is the pro vision of a radiator of this character in which the common inconvenienceand disadvantage of highly heating the floor 'beneath the radiator and the wall behind it, is entirely overcome, and substantially all of the heat. generated is radiated upwardly and outwardly into a room.

Burning or highly'heating the floor is prevented bythe use of the body of water which completely encircles the burner chamber. The products of combustion and hot gases from the burner escape through vents between the radiator sections, and baffle means is provided which throw such vapors forwardly into the room, effectively preventing them from scorching or overheating a wall behind the radiator. The radiator is preferably thermostatically controlled in any convenient or conventional manner so that a uniform temperature may be maintained.

Another object of the invention is to provide a radiator which may have the attractive appearance of an ordinary steam or hot water radiator, and will involve the use of no conspicuous structural features which might detract from its attractiveness.

Other and more general objects of the in.- vention are to provide a radiator of simple, 'practical construction which will be rugged, durable and efficient in use, and well suited to the requirements of economical manufacture.

With the above noted and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter set forth and pointed out in the claims. The invention may be more fully understood from the following description in connection with the accompanying drawings, wherein:

Fig. 1 is a view partly in front elevation and partly in vertical section through a radiator embodying the present invention.

2 is a vertical sectional view on the line 2 2 of Fig. 1.

1g. 3 1s a sectional plan view of the burner and 1ts associated parts.

Figs. 4 and 5 are plan, views of the two end closure plates for the burner chamber.

The radiator of the vpresentinvent-ion as stated above very closely resembles in exvertical sections,-each section includingthree spaced hollow columns 10 connected by upper and lower chambers 11, '11. The end sections of the radiator may include supporting legs 12 and the sections are connected by push nipples 13 entering aligned tapered openings 14 as well as bythe usual connecting tie bolts '15.

The cast sections are provided with cylindrlcal passageways 16 intersecting the lower chambers 11 and these passageways align to cooperatively define a burner chamber 17 within which is mounted a longitudinally extending burner consisting of the, tube 18 and the aperturedplate '19.

The lower portionzof the radiator contains water, the water level being always high enough to result in completely surrounding the burner chamber so that heat from the walls of the cylindrical passageways 16 will be transferred to the water and cause the generation of steam.

The burner chamber is provided with openings 20 between the adjacent radiator sections and the escaping hot gases and products of combustion are directed upwardly and forwardly by integral baffling flanges 21 carried by the sections. The flanges of the adjacent faces of adjacent radiator sections cooperate, as best seen in Fig. 1, to define baffle plates which prevent the hot gases escaping from the vents 20 from playing directly on a wall behind the radiator.

A valve. such as 22 may control the flow of gas to the pipe 18, and any convenientor conventional thermostatic means such as that indicated at 23, may be utilized to control the gas flow.

The ends of the burner chamber are closed by plates 24: and 25 providing mounting for the burner pipe 18 and means of attachment for the gas connections, thermostat etc. conventional safety valve may be provided at 26, and water introduced into 'ternal appearance a standard type of steam radiator bemg built up of a plurality of the radiator through a filling opening at 27.

From the foregoing description, it will be seen that I have provided a burner of a type which is highly efiicient in so far as the heat obtained from a given amount ofgas is con-' down in the chamber, and the flames do not impinge directlyon the walls of the vent openings.

There are no parts of the radiator which may burn or corrode, and in consequence the cost ofrepair and maintainance is slight. The radiator may be operated on any kind of gas, such for instance as illuminating gas, fuel gas, and natural gas.

This radiator is provided with the usual connections (not shown) so that it may be used in combination with a straight steam or hot water radiation system without making any alterations in the heater. Thus the device may function either as an independent unit or in connection with an ordinary system.

Various changes and alterations might be made in the general form and arrangement of parts described without departing from tions,

the invention. Hence I do not wish to limit myself to the precise details set forth, but shall consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. A gas heated steam radiator comprising a plurality of spaced and connected sections adapted to contain water in their lower pora transversely extending burner cham her in the lower part of the radiator and so located therein that it will be surrounded by Water, a gas burner in the chamber, said 7 chamber having openings in the top between the radiatorsections for the passage of the products of combustion, and bafiles extend,- ing upwardly and forwardly from thechamber adjacent the openings therein between the radiator sections for directing the prod,- ucts of combustion passing through said openings. 7

2. A gas heated steam radiator comprising a plurality of spaced and connected sec:

tions adapted to contain water in their lower portions, each radiator section having a cylindrical passage adjacent its lower end, said passages forming a transversely extending burner chamber and having their adjacent ends cut away to form openings in thetop of the chamber between the sections, said burner chamber being so located in the radiator that it will be surrounded by water, a burner in said chamber, and plates secured to the radiator at the ends of the chamber and in which the burner is mounted.
