SHEET-METAL CAN.

SPECIFICATION forming part of Letters Patent No; 245,371, dated August 9, 1881, Application filed June 11, 1881. (No model.)

To all whom it may concern:

Be it known that I, CHARLES GREEN, of Greenville, Delaware, have invented an Improvement in Sheet-Metal Cans, of which the following is a specification.

My invention relates, generally, to the class of sheet-metal vessels employed to hermetically contain liquidpaints, preserved edihles, powder, and kindred substances, and which are known in the trade as wire ripping provide means whereby the wire is with greater readiness retained in place during the process of securing the cover or sealing the can, and whereby strains upon the solder-envelope are lessened.

To the above ends my invention consistsin the improvement hereinafter described and claimed.

In the accompanying drawings, Figure l is a view, in perspective, of the cover of the can.

0 Fig. 2is asimilar view ofaband ofsheet-iron or other material to which solder will not adhere, employed in my former invention to prevent improper adherence of the solder. Fig. 3 is a similar view of the ripping-wire Fig. 4 is 3 5 a central sectional elevation of the upper portion of the can embodying my present im-, provement, with the cover represented as sealed in place; and Fig. 5 is a view, in perspective, of a closed and sealed can embody- 0 ingmyinvention.

Similar letters of reference indicate corresponding parts.

In the accompanying drawings, A represents a flanged cover, and B a band of sheet- 5 iron or other material to which solder will not adhere, placed between the flange of the cover and the chine of the can.

0 is the body of the can, D the ripping- Wire, and E the envelope of solder. These parts, in a given relative arrangement, con- 0 stitute the features of my former invention.

G is a circumferential corrugation formed in the upper portion of the can-body below the chine. It opens outward, and is of such depth and extent as to afford a means for locating and partially retaining the ripping-wire in the operation of sealing the can. In the provision of this circumferential groove, in combination with the members forming the elements ofmy former invention, this improvement consists.

In the sealing of a can constructed according to this improvement, after the cover has been placed in position, the wire is laid in the groove, in which position the wire resting in the groove comes in contact with the lower edge of the sheet-iron band only, or with the lower edge of both band and flange of the cover, and an envelope of solder extending from the lower edge of the flange to the body below the groove is then applied to secure the wire in place.

The advantage of my improvement is that it assists in locating and retaining the wire during the sealing operation, and also serves to relieve strains upon the solder-envelope, which heretofore alone retained the wire.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- In a sheet-metal can, the combination of a flanged cover, a body provided with acircumferential groove adapted to form a seat for a ripping-wire, aband or ring of sheet-iron, or other material to which solder will not adhere, between the flange of the cover and the body above the groove, a ripping wire seated in said groove, and a solder-envelope inclosing the wire and uniting the flange of the cover with the body of the can below the wire and the groove, substantiallyas and for the pur- 9o poses set forth.

In testimony whereofI have hereunto signed my name this 26th day of May, A. D. 1881.

CHARLES GREEN.

In presence of J. BONSALL TAYLOR, W. G. STRAWBRIDGE.
