What we claim asour invention, and desire to sc- 'cnre b Letters I'atent, is-

1. The method of closing the ends of Sheet-metal -eans bymeans of 'a count-ersnnk head 'or cap fitting within the orifice ,to be closed, and'provided with a flange, which rests. upon the npright edges of the can around the vorifiee, and is' formed, with said edges, into 'a ap-seem,` against anexternal mandrel, as a support, substantiaily as. shown and set'forth.

2.' The flaring lap-seam,formed by the union of the flange of the countersnnk head with the npright edges of the can suri'o'undingthe;ofiee to .which said head vis applied, substantiallyas and for thepnrposes shown and set forth.

3. A sheet -metal can, composed of flanged and.

countei'snnk h'eads, in combination with corrngated or bulgin sid'es, the two being united by a.lap-seam, form flsspecified, and -bronght within the Compass of the buiging sides, so that the s'eam or seams may be protected from injury, as hcrein set forth. 4. 'The 'orxnation of a groove 0x' recess in the body 'of the can, parallel with the iap-seam, and adjoining the edge ot' the tnrned-doivn fiange of the countersunk head or cap, as and'for the pnrposcsiset forth.

5. A. Sheet-metal can, one or both ends of which are closed by means of a flanged and conntersunk head or cap, applied and sccured to the can in the manner substantialiy as shown and. setfort'h.

lIn testhnony whereof; we have herennto set our hands, in the presence of two snbscribing witnesses.
