.SPECIFICATION forming part of Letters Patent No. 273,060, dated February 27,1888.

Application ijled January 2l. 1885.. (No model.)

T o all whom Ait may concern Be it known that we, L. EUGENE FULLER` and JOSEPH H. MACAULEY, both of Chicago, in the county ot' Cook and State of Illinois, have invented a new and useful Improvement in Sheet-Metal Cans,l of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l represents a vertical section of a sheet-metal can constructed in accordance with our improvement, and Figs. 2, 3, 4, and 5 diagrams illustrating different stages in the pro cess of forming the seam which unites a fixed cover with the body ofthe can.

This invention relates to sheet-metal cans which are designed to be used for packing and transporting` liquid paints, oolorsfor making paints, preserved fruits, meats, and other substances or articles which in order to preserve them from deterioration or injury require to be protected from exposure to the atmosphere, or which, by reason of their liquid consistency, are liable to escape by leakage.

The invention consists in a sheet-metal can having the mouth end of its body closed without solder by a countersunk fixed cover arranged to fit within said mouth or open end of thebody, and united with the body byarounded seam or joint formed by lrolling over the marginal portions of the open end of the body and as hereinafter described. Combined with this fixed cover and the body of the can is a slip lid or cover constructed to t over the fixed cover.

A indicates the bodyof the can, which may be made of sheet metal in the usual way, and preferably round, but which may be of other form.

Bis the bottom of the can, which may be Aunited with the body A by an ordinary soldered joint or otherwise.

C is an inner fixed top or lid,which is stamped from soft sheet metal, preferably taggers tin or taggers iron,7 and is formed with a countersink or depressed surface extending nearly the full width or area of the mouth or open end of the caubody, and so that the outer wall of such depressed portion will correspond to and t closely within the open end of the body of the can. The marginal or outer edge portion of this tixed cover extends beyond the countersunk portion of said cover, and when applied to the can-body has a pendent ange, which iits down or over an outer anged projection of the upper edge of the can-body, as shown in Fig. 2. The can having been lled with its contents, the seam is then closed by turning the pendent ange of the fixed co'ver under and up .against the under side of the flange on the upper edge of the can-body, thus making a single seam, as shown in Fig. 3. This seam is then turned down, as shownwin Fig. 4, and ultimately rolled under again, so that it forms a round scroll-like triple' seam, and so that the extreme edge portion b of the xed cover will be tucked up within the rolled-over edge portion c of the body and between it and the main portion ot" the can-body, as shown in Figs. l and 5. This gives a firm seam and avoids the expense and labor of soldering, and such round seam or joint is easier on the metal and less liable to crack when seaming than is a flat double seam. It also forms a tightjoint, and by being rolled over on the outside of the main portion of the body of the can, and the marginal portions of the open end of said body and of the fixed cover being not only pressed together but against the main portion of the body ot' the can, there is but little or no liability to leak. After the can has been thus closed a slip-lid, D, is applied tol the body of the can and over the fixed lid or cover C.

When it is desired to use the contents of the can the slip-lid D is removed and the extended countersuuk portion of the fixed cover C is cut away at or around the base of the wall ot' the eountersink by means of an ordinary pointed kuifeblade, thus leaving the wall of the countersunk portion of the cover C united to.

the body of the can, and forming, in connection with the seam on the outside of the can, a smooth and tirm edge, which supports and strengthens the upper edge of the can, and on 'or over which, when the can is used for holding paint, the paint-brush may be wiped or drawn without injury to it. After the iixed cover has been removed the slip lid or cover IOO can be used to cover and protect the contents The combination', with the can-body A, hav"- of the can against dust und the action of the ing its upper edge turned over, ot the counteratmosphere. f sunk fixed cover C, carried over and turned A paint-can constructed as described reunder the body-edge, and the extreme portion x5 5 quires less labor to make it and can be furb tucked up between the rolled portion a and nished to the trade at less cost than a can havthe body, as shown and described.
