PATENT OFFICE.
STEAM-RADIATOR.
SPECIFICATION forming part of Letters Patent No. 273,066, dated February 27, 1883.
Application filed December 9, 1882- (No model.)
To all whom it may concern:
Be it known that I, ABNER A. GRIFFING, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Steam-Radiators, of which the following is a full, clear, and exact description.
The object of the invention is to so construct a radiator-tube and its interior airpipe that a maximum of heat will be applied to the air as it circulates through the interior pipes.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation, partly sectional, of a radiator with my improvements. Fig. 2 is a longitudinal section of one of the tubes in larger size. Fig. 3is a longitudinal section at right angles to Fig. 2. Fig. 4 is a transverse section on line a: 00, and Fig. 5 a transverse section on line 3 3 Fig. 3.
A are the steam-tubes. B is the base,and G the cap, of the radiator. The tubes A are of flattened or oval form throughout their whole length, except at their upper ends, which are swelled to a circular form. At their lower ends they are formed with threaded flanges or bosses at, that are screwed into the upper plate of the base B. Through the center of the steam-tubes air-tubes 61 pass, these air-tubes being screwed into the bottom plate of the base B and into the upper ends of the steamtubes A, so as to form internal passages for air from the under side of the base B to the cap 0. The external diameter of the air-tubes d corresponds to the internal shorter diameter of the steam-tubes, so that there is contact between the exterior surface of the air-tubes and the interior surface of the steam-tubes, and the steam-tubes are thereby divided into two longitudinal passages for circulation of the steam, the two passages being connected at the upper end by the enlargement of the steam-tubes at that point. By this construction and arrangemeant I obtain a largely-increased heatiugsurface in proportion to the size of the steam-tubes and insure a greater upward circulation of air. I do not limit myself to this special construction and arrangement, as they may be varied within the scope of my invention.
1 am aware that air-circulating pipes have been formed in steam or hotwater heating tubes by runuin g two parallel partitions across the inside of a tube laterally open above the bottom for the reception of air and closely covered at the top, below the top of the tube.
What I claim as new and of my invention 1s- The'combination of a flattened or oval tube, A, swelled out in a circular form at the upper end, with a circular interior air-tube, d, in contact with the sides of said tube A, to form a steam-radiator tube, as shown and described.
