UNITED STATES PATENT OFFICEo GEO. D. GREENLEAE, OF THREE MILE BAY, NEV YORK.

STOVE-PIPE DRUM.

Spcciiication forming part of Letters Patent No. 17.945, dated May 30, lta').

To all whom may 0071.081172,.-

Be it known that I, GEORGE I). GREEN- LEAEof Three Mile Bay, in the county of Jefferson and State of N ew York7 have invented a new and Improved Heat-Radiator for Stoves; and I do hereby declare that the following isa full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specication, in which- Figure 1 is a vertical central section of my invention; Fig. 2, a horizontal section of the same, taken in the line .fr w,'Fig. l.

Similar letters of reference indicate correspending parts. A

This invention relates to a new and improved heat-radiator to be applied to stovepipes for the purpose of radiating the heat, which would otherwise escape intothe chimney.

The invention consists in a novel arrangement of draft passages or rines placed within a drum,and provided with dampers in such a manner that either a direct or sinuous draft may be obtained within the drum, as required.

A represents a drunnwhich may be of cylindrical or oval form, the latter being preferable. This drum is provided at its upper and lower ends with collars B, to receive the joints or pieces of stove-pipe with which the drum communicates. Vithin this drum there are placed and permanently secured four within the drum A, and is in line with the collars B B, and said flue a has a damper, C, at its upper and lower ends, the two dampers working on pivots c at the centersof their ends, and connected by arms d with a vertical rod, D, the lower .end of which projects through the bottom of the drum. By thus connecting these dampers they are both moved simultaneously by actuating the rod D. When the dampers C are open, a direct draft is obtained through the flue a, as indicated by the dotted arrows in Fig. 1,and when the dampers are closed asinuous draft is obtained, the pro-y ducts of combustion passing up through ilue a" into the upper part of flue a, down the latter into the lower end of iiue c, up the latter into the upper end of iiue am', and down ilue 60 into the lower end of iiue am, and up said iiue into the stove-pipe, as indicated by the solid arrows. By this arrangement avery ci rcuitous draft is obtained and a large amount or volume of heat radiated into the apartment in which the drum is placed, and at the same time, when a direct and strong draft is required-as in kindling a fire, for instanceit may, by a simple adjustment ofthe dampers, be obtained.

I claim as new and desire to secure by Letters Patent- The combination, in heat-radiators for stoves, of the drum A, iues a a a am aw, :arms d d, 'and rod D, substantially as and for the pun poses set forth.
