UNITED STATES PATENT OEEIcE. a
THOMAS P. HARDY, OF MARION, NEW JERSEY, ASSIGNOR TO PETER P.r KELLER, OF NEW YORK CITY.
IMPROVEMENT IN STEAiM-RADIATORS.
Specication forming part of Letters Patent No. 216,400, dated June 10, 1879; application filed f December 11, 1878.
To all whom it may concern.-
Be it known that I, THOMAS' P. HARDY, of Marion, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Steam-Radiators, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure l represents a sectional elevation of a steam-radiator constructed according to my invention. Fig. 2 is a horizontal section of one of the radiating-tubes on a larger scale than the previous figure. Fig. 3 is a longitudinal sectio'n of the same in the plane a' x, Fig. 2. Fig. 4 is a similar section in the plane y y, Fig. 2. Fig. 5 is a transverse section of a modification thereof.
Similar letters indicate corresponding parts.
This invention consists in a radiating-tube provided with one or more depressions, which commence near the open foot of the tube, and terminate within a short distance from the closed top thereof, leaving a narrow channel opposite their inner edge or edges, a steamchamber above, and two more steam-chambers on opposite sides of and connected by said narrow channel, so that the radiatingsurface of the tube is increased, and a circulation of the steam through said tube is effected.
In the drawings, the letterA designates my radiating-tube, which is preferably made of cast-iron, and which is open at its foot and closed at its top. On opposite sides of said tube are formed depressions a a, which commence near its open foot and terminate within a short distance of the closed top, thereby forming a chamber, b, and two chambers, c c, on the sides of the tube, while an open channel, d, extends from the chamber b down to the open foot.
In the example represented by the drawings I have shown a radiating-tube with two depressions, aa but, if desired, the number of depressions may be increased, or the tube may be formed with only one depression, as shown in Fig. 5.
The radiating-tubes A are secured in a base, B, of the ordinary construction, and if steam is admitted to the same it passes up through the chambers c c, and down through the narrow channel d, between or opposite the inner edges of said depressions, thereby creating a circulation which materially increases theheating capacity of my radiator.
Furthermore by providing the tubes with depressions a. a, their radiatingsurfaces are increased, and a radiator is obtained which produces a superior heating eiect with comparatively little expenditure of steam.
What I claim as new, and desire to secure by Letters Patent, is-
A metallic radiatingtube formed in one piece, and provided with one or more longitudinal depressions, which commence near the open foot of the tube and terminate within a short distance from the closed top thereof, leaving a narrow channel, d, a steam-chamber above, and two at opposite sides of and connected by said narrow channel, substantially as and for the purpose set forth.
In testimony that I claim the foregoing I have hereunto set my hand and seal this 4th day of December, 1878.
