V. WI-LHELMI.
RANGE BOILBR.
No. 602,650. Patented Apr. 19,1898.
llNTTEn STATES PATENT @Errea VALENTIN WILHELMI, or 'rATERsoN NEW JERSEY.
RANGE-BOILYER.
SPECIFICATION forming para of Len-.ers ratent No. 602,650, dated April 19, 189s.
Application filed October 20, 1897.
To all whom t may concern:
Be it known that l, VALENTIN WILHELMI, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Range-Boilers, of which the following is a specication.
This invention relates to certain improvements in range-boilers of that class which are made of copper and the cylindrical body of the boiler is connected with a bulging top and bottom by an overlapping retaining-ring which is lirmly brazed with the overlapping parts of the body and ends and in which the reinforcing interior iron ring heretofore used can be dispensed with while an equally strong and reliable construction of the boiler is obtained; and the invention consists of a rangeboiler consisting of a body having a iiattened ring portion offset therefrom, so as to form a shoulder at its junction with the body and being of greater diameter than the diameter of said body, a head having an offset-rim forming a shouldered flange of greater diameter than the body thereof, the shouldered flange of the head overlapping said iiattened ring portion and being throughout in rm contact therewith, and said ange also terminating short of the shoulder at the base of said ring portion, and an exterior band extending over the said ring portion and the overlapping portion of the head, the upper and lower edges of said band fitting over the shoulders on said ring portion and iiange so as to form a three-ply joint from the inner surface of said body to the outer surface of said band, as will be fully described hereinafter and finally pointed out inthe claim.
The drawing illustrates a vertical central section of my improved ran ge-boiler complete.
Similar letters of reference indicate corresponding parts.
Referring to the drawing, A represents the body of my improved range-boiler, which is made of copper. The interior of the body is reinforced by annular ribs a, that are brazed to the inside of the body, so as to prevent the collapse of the" same by pressure. The ends of the body A are provided with shoulders or offsets d', from which shoulders or offsets the body of the boiler is extended, forming cylindrical flattened ring portions a2 Serial No. 655,811. (No model.)
of slightly larger diameter than the diameter of the body. The extremities of the body are again shouldered or offset at as, forming cylindrical rims a4, which are of substantially the same diameter as that of the body and slightly curved to conform to the curvature of the heads. These shoulders a a3 and the cylindrical flattened ring portions a2 form a means of attachment for the heads B B' and the reinforcing rings or bands C C spun around the same. The heads B B are curved or bulged at their upper portion and are provided with shoulders or offsets l), which rest upon the shoulders a3 and from which shoulders the rim b' of the heads B B' extend, which rims are of a diameter somewhat greater than the diameter of the beads or corrugations a2 of the body A of the boiler, so as to form a close fit thereon. The edges of the rims b terminate short of the connectingshoulders a between the body A and the ring portions a2. By means of the rims c4 at the ends of the body A, said rims being contracted and curved to conform to the shape of the larger bulged portions of the heads B, the latter are rmly and solidly braced and strengthened. The exterior rings or bands C C are spun or brazed over the shoulders a of the body A and the shoulders b of the heads, covering the points of connection or seams between the heads and the body A, so as to impart thereto the required strength. After the heads are applied to the body of the rangeboiler and the rings or bands C C spun thereon the joints are thoroughly sweated together with solder. The ring portions a2, the rims b, and the exterior bands c form a three-ply joint from the inner surface of the body of the boiler to the outer surface of said bands. The attened beads or corrugations give additional strength to the ends of the rangeboiler when the heads B B and exterior bands or rings `C C are being brazed thereon, thus doing away with the necessity of employing iron strengthening bands or rings upon the inner surface of said boiler, as is customary in boilers of the usual construction.
By the construction described a very strong range-boiler is obtained, by which the heads are rigidly and tightly attached to the body of the boiler and by which a neat and ornamental appearance is imparted to the same IOO without the objectionable bulging at the joints and seams as heretofore required. Furthermore, the heads are by my improved oonstruction attached to the body of the boiler so as to be leak-proof, and the heads cannot be loosened by an accidental blow or by unusual pressure tending to drive them downward, as maybe done With boilers constructed in the ordinary manner. The boiler is finally put through a finishing process and polished -in a manner Which gives it a handsome appearance.
Having thus described my invention, what I claim is- A range-boiler, consisting of a body having a flattened ring portion oset therefrom and of greater diameter than the diameter of said body, the said ring portion being provided with an offset and terminatingin a cylindrical rim of substantially the diameter of the body as set forth.
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.
VALENTIN WILHELMI.
