IRON RANGE (30., OF ST. LOUIS, MISSOURI.
STEAM-JAICKETED KETTLE.
SPECIFICATION forming part of Letters Patent No. 770,045, dated. September 13, 1904.
Application filed January 29, 1902. Serial No. 91,656. (No model.)
To all whom, it may concern.-
Be it known that I, WVALTER L. OULVER, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Steam-Jacketed Kettles, of which the following is a full, clear, and exact description,
reference being had to the accompanying drawings, forming a part hereof.
My invention relates to steam-jacketed kettles; and it consists of the novel features herein shown, described, and claimed.
In the drawings, Figure 1 is a sectional perspective of a kettle embodying the principles of my invention. Fig. 2 is a vertical sectional view of the base and cylinder.
Referring to the drawings in detail, the base 1 is a hemispherical casting cored to form a jacket and is provided with a drainage-opening, to which a faucet or similar device may be attached. The base is mounted upon supports 2. The cylindrical body 3 has a reinforced lower edge, the inner surface of which is curved inwardly, so that the base maybe inserted downwardly through the cylinder and driven tightly into place before the rivets are applied to connect the cylinder to the base, and a quantity of solder 4 is inserted around the upper edge of the base to make a smooth continuous surface between the base and the cylinder. The inner surface of the base and the cylindrical body are tinned separately or otherwise suitably finished. A flange 5 is attached to the upper edge of the cylindrical body, and a cover 6 is mounted upon the flange. The capacity of the kettles is varied by making the cylindrical body 3 longer or shorter.
It is of great importance that the base and the body of the kettle be made separately, as it is impractical and almost impossible to handle a large size kettle for tinning and finishing all in one piece or after the pieces have been attached together. It is also very difficult to make a tight joint between the base and the cylindrical body with the practice in vogue previous to my invention. Itherefore desire to call especial attention to the cylindrical body having a reinforced lower edge, the inner surface of which is curved inwardly to reduce the diameter of the cylinder, in combination with a hemispherical cast base adapted to be inserted downwardly through the cylindrical body and driven tightly into position before the rivets and finishing touches are applied. If the lower edge of the cylindrical body were simply corrugated or hammered inwardly without first reinforcing the lower edge, this edge would split when applied to the base, and it would be impossible to make a good substantial joint; but when this lower edge of the cylindrical body is reinforced the base may be driven tightly into position without splitting the edge, and then the rivets may be applied and the solder applied and the tight joint produced.
What I claim is 1. In a steam-jacketed kettle; a hemispherical base cored to form a jacket; and a cylindrical sheet-metal body having at its lower edge an integral reinforcement, the inner surface of which is curved inwardly to decrease the diameter of the cylinder and to tighten up around the hemispherical base; substan tially as specified.
2. In a steam-jacketed kettle; a cylindrical sheet-metal body having an integral reinforcement at its lower edge, the inner surface of which is curved inwardly to decrease the diameter of the cylinder; in combination with a hemispherical base cored to form a jacket; said base being inserted downwardly through the cylinder and driven tightly into position within said reinforcement; and rivets inserted through the reinforcement and through the upper edge of the base; substantially as specified.
In testimony whereof I afiix my signature in presence of two witnesses.
WALTER L. OULVER.
