FREDERICK WESTERBEOK, OF ST. LOUIS, MISSOURI.

SHEET-METAL CAN.

SPECIFICATION forming part of Letters Patent No. 591,313, dated october 5, 1897.

Application filed December 14,1896. Serial No. 615,683. (No model.)

To all whom t may concern/.f

Be it known that I, FREDERICK WESTER- BECK, a citizen of the United States, and a resident of the city of St. Louis, in the State vof Missouri, have invented a certain new and secured to the can-body by folding or rolling over the body and cover inwardly together into a secure seam, such Construction obviating the use of solder or other sealing material in attaching the cover to the can. W

My invention consists in .features of novelty hereinafter fully described', and pointed out in the claims. I

Figure I shows an elevation of myim proved can. Fig. II is an enlarged detail vertical section of the can-cover. Fig. III is an enlarged detail vertical section of the upper portion of the can-body. Fig. IV is a side view, enlarged, of the stiffener applied to the body ofthe can. Fig. V is an enlarged detail vertical section of a portion of the can body and cover before the application of the stiffening band` and before the body and cover have been joined together. Fig. VI is a similar view to Fig. V with the stiifeningband applied and the seam formed to connect or join the Can body and cover.

In the drawings, l designates the body of the can, provided at its upper end with an inturned shoulder 2 and an outturned shoulder 3. Immediately beneath the outturned shoulder 3 is abead 4, projecting into the interior of the can-body. Extending upwardthe shoulder 3.

4 fitting within the extension 5 of the canbody. A

9 designates a stiifening-band that fits in the channel 6, its lower edge resting upon the shoulder 2 and its upper edge fitting against The stiffening-band 9 is provided for the purpose of preventing the body of t-he can from buckling or collapsing in the act of forming the seam that joins the body and cover of the can.

The joining-seam is designated by 10, (see Fig. VI,) and as this seam is produced in a forming-machine of very considerable power the production of the seam has a great tendency to cause the body of the can to buckle or collapse immediately below the can-cover. The stiening-band 9 prevents such occurrence.

I Claim as my inventionl'. In a sheet-metal can, the combination of a Can-body provided withan inturned shoulder, an outturned shoulder, a stiftening-band located in the channel formed by the shoulders and fitting between said shoulders, a vertical extension above said outturned shoulder, and a cover provided with a flange and located within the body, said eX- tension and flange being arranged to be folded over inwardly together into a seam, substantially as described.

y 2. In a sheet-metal can, the combination of a can-bodyl provided with an inturned shoulder,an outturned shoulder,an inwardlyprojecting bead located beneath said outturned shoulder,y a stiifening-band located in the channel formed by the shoulders and iitting between said shoulders, an extension above said outturned shoulder, and a cover provided with a Iiange and located within the body, said extension and iiange being arranged to be folded over inwardly together into a seam, substantially as described.
