EDWARD H. WHITNEY, OF CAMBRIDGE, ASSIGNOR TO THE DOVER STAMPING COMPANY, OF BOSTON, MASSACHUSETTS.

SH EET-METAL VESSEL.

SPECIFICATION forming part of Letters Patent No. 254,417, dated February 28, 1882,

Application filed December 7, 1881. (F0 model.) i

To all whom it may concern Be it known that I, EDWARD H. WHITNEY,

of Cambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement inthe Construction of Sheet-Metal Vessels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature, in which Figure 1 is a vertical section of a slop-jar made in accordance with my invention. Fig.2 is a perspective of the slop-jar with the foot re moved from the bottom. Fig. 3 is a vertical section of a portion thereof enlarged, more clearly representing the construction.

This invention is applicable to all classes of vessels having a bottom and foot portion, generally known as stamped ware, and including coal-hods, slop-pails, 850.

In the drawings I have represented my invention as applied to a slop-jar, and A represents the body of the jar. The bottom B is formed in the usual manner with the lower edge turned outwardly and upwardly to form the upwardly-projecting flange b, which has the downwardly-projectingextension b, as represented in the drawings, making, as it were, a hook-flange, and this hook-flange is of a size to close over the upwardly-projecting flangea of the body, and thejoint thusformed may be consolidated in any suitable manner. This is the common method of construction. The foot part or base 0 is struck up from a ring, or from a disk of metal from which the center has been removed, to the shape shown in Fig. 2, and is united to the bottom of the pail by the rivets 0 through the bottom B to the inside of the jar.

The jar or pail thus constructed is strong and cheap, and is held together without the use of solder orits equivalent, and this I esteem to be of advantage,because it enables me to galvanize the vessel by dippingin hot metal without any liability of the parts becoming separated, as they are very likely to do when solder is used as the means of fastening the parts together; but of course I may solder the bottom to the body without departing from the spirit of my invention.

I prefer that the foot or base have the shape shown in Figs. 2 and 3, or a shape to partially inclose the joint formed by uniting the bottom and body; but of course the flange may project inwardly from the upper level of the base, if desired.

The circular piece that is removed from the disk used in making the base can be utilized for other purposes.

Of course Imay use any desirable metal for making the vessel.

The exterior of a vessel thus formed has a very finished and even ornamental appearance, which I conceive to be another advantage.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- A hollow sheet-metal vessel comprising the body A, thebottom B, united to the body, substantially as specified, and the base G, struck up from a ring or disk of metal from which the center has been removed and fastened to the bottom B by rivets, all substantially as set forth.

EDWARD H. WHITNEY.
