RADIATOR.

SPECIFICATION forming part of Letters Patent No. 716,906, dated December '30, 190 2% hpplication filed March 24, 1902. Serial No. 99,568. (No model.)

To aZZ whom it may concern:

Be it known that I, ALFRED EDWARD LAY- COCK, a subject of the King of Great Britain,

residing at Moosoniin, county of Assiniboia, North-West'lerri-tories, Oanada,haveinvented certain new and useful Improvements in Radiators; and I do hereby declare that the following is afull, clear, and exact description livering it in the form of hot air into an apart mentor room and likewise to radiate the heat therefrom, so as to assist in heating said room.

My improved radiator is adapted either to be used in addition to the stove in the same apartment therewith and immediately thereover, whereby to increase the capacity of the stove for heating the apartment, or it may be placed inan upper apartment through which the flue pipe of the stove is carried and whereby the stove is enabled to heat simultaneously two apartments without any additional appliances, such as hot-air and coldair boxes, registers, steam-circulating means and the like, which greatly add to the expense of heating a house.

Myinvention consists, essentially, inan enlargement of the Stovepipe comprising a pcculiar arrangement of concentric cylindical or annular chambers, which are adapted alternately to contain the smoke or flue gases and to form circulating passage-ways through which the air of the room is adapted to pass.

My invention :further consists in the peculiar combination and construction of parts hereinafter more specifially set forth, and which will be particularly pointed out in the claims.

In the drawings formingapartof this specification, Figure 1 represents a vertical crosssection through a house, showing a stove with my improved radiator in the flue-pipe thereof in elevation. Fig. 2 is a central longitudinal sectional elevation of my improved radiator as usually mounted, and Fig. 3 .is a similar view showing my improved radiator as reversely mounted and provided with an attachment particularly fit-ting it for use with hard-coal fuel.

ported upon a foundation 8. The stove adapted to heat the lower apartment is indicated I j at 9, and it has a vertical flue-pipe 10, extending upwardly through the floor-.6 and into the upper apartment 5, and in that part which extends through the apartment 5 is provided my improved radiator, (designated by the numeral 11.) As herein shown, this radiator comprises a cylinder of sheet-iron 12, considerably exceeding the diameter of the stovepipe' and connected. therewith by reduced conical ends 13, having parallel flanges 14:, into which the ends of the Stovepipe 10 telescope. In the interior of this sheet-iron cylinder is located a similar but smaller concentric cylinder 15, which is solidly connected to the outer. cylinder by a pair of short cylindrical openings 16 at opposite extremities of a diameter located at the upper end, and

a similar pair 17, located at the lower end thereof, thus connecting interiorly the cylinder l5 witlrthe exterior of the radiator, while separating both from theintermediate annular space 18. Within the cylinder 15 there is another concentric piece 19, herein shown as somewhat conical in form, and tapering smaller toward the top, as I have found this form gives improved results in a manner which will be stated presently. This cone 19 is of slightly less length than the cylinder 15 and is connected therewithat top and bottom by dished annular plates 20 21, respectively, thus forming an annular closed chamber 22 between the cylinder 15 and cone 19 of roughly quadrangular section, which chamber is connected with the outside air of the apartment by the apertures 16 and 17, as above mentioned. The inner conical space 23, formed within the cone 19, is subjected to the action of the fluegases which pass therethrough, and its upper end is suitably closed by a damper in the form of a butterfly-valve 24:, having a shaft 25, which is pivoted at 26 in the walls of the cone,19 and extends upwardly through one of the apertures 16 and is provided with a cross-bar 27 to form a handle for turning the valve.

The flue-gases in passing up through the flue-pipe 1O impinge upon the dished plate 21 and are separated into two portions, one passing around through the annular chamber 18 and the other passing up through the conical chamber 23, and in both cases they part with a portion of their heat to the outside air of the apartment and to that which circulates in the air-chamber 22. These two portions of the fine-gases again join one another in the upper cone 13 of the radiator and pass out through the continuation of the flue-pipe 10, as indicated by the arrows. The airinlets 17, being separated by a quarter-circle from the air-inlets 16, cause more thorough circulation of the air through the inner chamber 22 than if they were located one above the other.

In Fig. 3 I have shown precisely the same device as in Fig. 2, and it is accordingly indicated by the same reference-numerals; but I have also shown in addition a funnel-shaped member 28, which is inserted through the upper end of the radiator within the flue-pipe,

as I have found this arrangement specially advantageous when hard coal is burned in the stove, because it causes a longer period of radiation and more thorough circulation of the flue-gases around the air-chamber 22 than where the upper end of the chamber 23 is simply open. This therefore illustrates the fact that myimproved radiator is reversible, and its two opposite positions are suitable for different conditions, as will be found by experience.

The object in having the plates 20 21 dished or concave is that it greatly strengthens the air-box in the flue and prevents warping or distortion of the metal in great heat.

While I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make such modifications as are included in the scope of the following claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A flue-radiator comprising a cylindrical casing having conical ends adapted to telescope into the flue, an air box or chamber supported therein having a concentric cylindrical outer wall, a concentric conical inner wall and dished annular end plates, a pair of passages forming supporting means for the air-chamber at opposite extremities of a diameter connecting the interior of the air-chamber with the outside air and at one end thereof, another pair of passages connecting the interior of the air-chamber with the outside air at the other end thereof, the last-named pair of passages being at an angular distance of ninety degrees from the first-named pair, and a damper operated by a handle extending through one of said passages, said damper closing the interior passage for the flue-gases.

2. A flue-radiator comprising a sheet-metal cylinder having conical reduced ends, an annular cylindrical air-box supported concentrically in said cylinder whereby to divide the flue-gases into two portions, a damper closing the inner passage-way for the fluegases, circulating-apertures connecting the interior of the air-box with the outside air, and a funnel-shaped pipe depending from the upper end of said radiator.

3. A flue-radiator com prising a cylindrical casing adapted to form a portion of a flue, an air box or chamber supported therein having a concentric cylindrical outer wall, a concentric conical inner wall tapered from top to bottom and dished or concaved annular end plates connecting said walls, in combination with a conical baffietube suspended from the upper end of the casing and depending within said inner conical wall and having its sides approximately parallel thereto, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
