UNITED STATES PATENT OFFICE-O AND CONSTANTINE RIES, OF THE SAME PLACE.

STOVE-PIPE DRUM.

To all whom it may concern: I

Be it known that I, WERNER Knonena, of Milwaukee, in the county of Milwaukee and State of Wisconsin, haveinvented a new and Improved Heat-Radiator; and I do hereby declare that thefollowin g is afull, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure i represents a vertical central section of this invention. Fig. 2 is a horizontal section of the same, taken in the plane indicated by the line 00 w, hig. 1.

Similar letters of reference indicate like parts.

This invention consists in a heat-radiator composed of three concentric cylinders and three dampers, the second or middle cylinder being separated in two parts by two horizontal partitions in such a manner that the draft'can be made to pass through the central pipe in a direct course, or that the heated gas can be compelled to pass up and down in a zigzag course, whereby the smoke is consumed and a large amount of heat radiated; and, furthermore, the chamber inclosed by the two horizontal partitions forms an airheater, which materially assists in raising the temperature of the room without requiring an additional quantity of fuel.

A represents a heat-radiator constructed according to this invention. It is composed of three concentric cylinders, a, b b, and c. The outer cylinder or drum, to, is made in one piece throughout, and it is contracted at both ends to correspond to the size of the inner cylinder, 0, or nearly so, and also to conform to the ordinary size stove-pipes. Said drum is divided in three compartments, d e f, by

'two horizontal partitions, g g, which form the support of the inner cylinder, 0, and which separate the second or middle cylinder in two parts, 11 I), as clearly shown in Fig. 1 of the drawings. These two parts are held in position by suitable braces, and they are provided Specification forming part of Letters Patent No. 55, 119, dated June 5, 1866.

with dampers h it, one of which is situated on the bottom part of the cylinder b and the other in the top part of the cylinder 1). An additional damper, t', is sitnatedin the bottom end of the drum (0. Suitable air-holes jj on diametrically opposite sides otthe middle compartment allow the external air to circulate in said compartment and to form an aireheater.

It all the dampers are opened, the heated gases or the draft pass through the drum and the inner pipes as through an ordinary Stovepipe; but if the damper h is shut the heated gases pass up between the drum and the cylinder I) until they strike the partition g,- then they descend through the cylinder 1) until they strike the damper h, and then they ascend through the inner cylinder, 0. If the damper h is also closed, the gases on coming in contact therewith are again compelled to descend, and caused to pass out at the bottom end of the cylinder 7) and out through the top of the drum a. While the heated gases pass down through the cylinder 1), after they have come in contact with the lower partition, g, much smoke is consumed as it comes in contact with the highly-heated surfaces, and by checking the draft again by the damper 72/ all the heat is made available.

By this arrangement a heat-radiator is ob tained which insures a capital draft and obviates all smoking, the smoke being consumed to a remarkable degree. It also forms an airheater of good efiect, and it workswith great economy of fuel.

What I claim, and desire to secure by Letters Patent, is-

A heat-radiator composed of three concentric cylinders, a, b b, c, in combination with two horizontal partitions, g g, and dampers 71, h i, all constructed and operating substantially 111 the manner and for the purpose herein set forth.
