RADIATOR OR OTHER HEATING-STOVE HEATED BY GASEOUS FUEL.

Specification of Letters Patent.

Patented Sept. 27, 1910.

Application filed July 12, 1909. Serial No. 507,121.

To all whom it may concern:

Be it known that we, HAROLD NEwsoM DAVIS, a subject of the King of Great Britain and Ireland, residing at 4 Lansdowne road, Luton Beds, and WALTER RATLEDGE Twice, a subject of the King of Great Britain and Ireland, residing at 71 Alleyn Park, West Dulwich, Surrey, England, have invented certain new and useful Improvements in Radiators or other Heating-Stoves Heated by Gaseous Fuel, of which the following is a specification.

' This invention for improvements in radi ators heated by gas relates to radiators of that type in which the products of combustion from the gas flame pass through a central tube out at the end and then into and through the annular space between the central tube and an outer tubeand this inven tion has for its object, instead of passing the products from the end of the central tube to the annular space, to distribute the products of combustion from the central tube to the annular space over the whole of the annular space so that the temperature of the outer tube shall be uniform throughout and consists in closing the end of the inner tube and in providing openings from the central tube to the annular space arranged and proportioned so that the outer tube shall be uniformly heated.

In the accompanying sheet of illustrative drawings, Figure 1 is a horizontal sectional view of one section of a single column radiator; Fig. 2 is a similar view of one section of a double column radiator; Fig. 8 is a sectional view of two sections of a single column radiator on the line XY in Fig. 1 and Fig. A is a sectional elevation taken along VW.

The radiators are made in any desired number of sections and each radiator section comprises the outer tube or shell A and the central tube B extending from the base of the shell A almost to the top thereof. The tubes are suspended from the bolt E which also securely holds the shells A together and are held in position at their lower ends by the tube plate G which also holds the base of the shells together. The ends of the two end shells are closed by large solid washers F. The tubes B are open at the lower ends and are closed at the upper ends by the plugs C and are perforated at the sides with holes D. The burner H is supported below I the tube plate G by feet K on the end shells and is provided with jets L one jet for each central tube B and arranged centrally under the tubes. The products of combustion pass up the tube B and out through the perforations D into the outer shell A thus causing the whole of the apparatus to become heated.

WVhen working, within the tubes B, there is a very high'temperature, and therefore a strong upward tendency of the gases, but in the annular spaces between the tubes B, and the shells A, the temperature is not so high owing to the loss of heat by radiation from the outer surface of the shell A, therefore the upwardtendency in the annular space is less than that within the tubes B, thus allowing the products of combustion to leave the apparatus from outlets arranged in any suitable position in the shells A. In the drawings these outlets are shown at the base as M. and N.

What we claim and desire to secure by Letters Patent, is

1. A radiator section comprising in combination, an outer shell closed at its upper portion and provided with an outlet near its base, a tube having openings arranged lengthwise thereof and disposed in said shell and extending substantially throughout the length thereof, and a burner delivering products of combustion to the bottom of said tube.

2. A radiator section comprising in combination, an outer shell provided with an outlet near its base, a tube having openings arranged lengthwise thereof and disposed in said shell and extending substantially throughout the length thereof and having its lower end extending through said shell and a burner delivering the products of combustion to the bottom of said tube.

3. A radiator section comprising in combination, an outer shell provided with an oulet near its base, a tube having openings arranged lengthwise thereof and disposed in said shell and extending throughout the length thereof and having its lower end extending through said shell, means at the upper end of said shell for suspending the tubes therein, and a burner delivering the prlgducts of combustion to the bottom of said tu e.

4:. A radiator comprising in combination, a plurality of distinct units communicating with each other at their lower ends and comprising a shell provided with an outlet near its base, a tube having openings arranged lengthwise thereof and disposed in each of said shells and extending substantially throughout the length of said shells, and a burner delivering the products of combustion to the bottom of said tube.

5. A radiator comprising a plurality of distinct units communicating with each other at their lower end each unit comprising a shell provided with an outlet near its base and closed at its upper portion, a tube in each shell provided with openings arranged lengthwise thereof and delivering to such shell, said tubes extending substantially throughout the length of said shells, the upper ends of each tube being closed, a wall portion closing the lower end of said shells, and a burner projecting through the bottom wall portion and delivering the products of combustion to said tubes.

6.'A radiator comprising a plurality of distinct units communicating with each other and each unit comprising a shell provided with an outlet near its base and closed at its upper portion, a wall closing the lower ends of said shells, a tube in each shell provided with openings arranged lengthwise thereof and extending substantially throughout the length of such shell and downwardly through said bottom wall, a burner below said lower or bottom walls delivering to said tubes, and means located wholly in the upper portion of said shells for centering said portion therein.

7. A radiator comprising a plurality of distinct units vertically disposed and communicating with each other near their lower end, a bottom wall closing the lower ends of said shells, said shells being closed at their upper portions and having outlets at their lower ends, a tube for each shell having openings arranged lengthwise thereof, and closed at their upper ends and provided with openings at their lower ends and projecting through said bottom wall, a burner delivering to said tubes and a rod for uniting the upper ends of said units or shells and eX- tending through said tubes to suspend the same wholly at their upper ends.

In testimony whereof we have aifixed our signatures, in presence of two witnesses.
