SHEET-METAL VESSEL.

SPECIFICATION forming part of Letters Patent No. 595,800, dated December 21, 1897. Application filed January 23, 1897- Serial No. 620,318. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE ACKERMANN, of Cincinnati, Hamilton county, Ohio, have invented certain new and useful Improvements in Sheet-Metal Vessels, of which the following is a specification.

This invention pertains to improvements in sheet-metal vessels, such as cans and buckets, designed for containing fruit, vegetables, paint, &c.

My improvements will be readily understood froin the following description, taken in connection with the accompanying drawings, in which- Figure 1 is an elevation of a paint bucket or can exemplifying my invention; Fig. 2, an elevation of the same, part diametrical vertical section, the ripping-tool being shown in position for use; and Fig. 3, a diametrical vertical section at a top portion of the vessel, this view being upon an enlarged scale.

In the drawings, 1 indicates the body of the vessel, the same being of cylindrical form and open at its top; 2, an outward swell or enlargement on the body a short distance below the rim thereof, this enlargement being tapered above to form a tapering shoulder enlarging downwardly; 3, the cover of the vessel; 4, the flange of the cover, the same capping down over the rim of the body and fitting over the rim freely and seating snugly upon the tapering shoulder formed by the enlargement 2; 5, a soldered seam at the juncture of the foot of the flange 4 with the body, this soldered seam forming the union and closure between the body of the vessel and its cover; 6, a bead surrounding flange 4 and formed by outwardly beading the metal of the flange, so as to leave the flange provided with an inwardly-open groove; 7, a ripping-wire disposed in the interior of bead 6; 8, the free end of this ripping-wire projected outwardly through a hole punched in the periphery of bead 6; 9, the ripping-tool, consisting of a handled stem or key having near its end a transverse perforation adapted to engage the projecting end 8 of the rippingwire; 10, a false wiring formed at the rim of the body and projecting inwardly; 11, a downward projection given to the top portion of the cover below the plane of the top of flange 4 and extending out to near the flange and resulting in a downwardly-open groove at the top of the flange, the periphery of the depression 11 fitting neatly within the rim of the body, and 12 the bail.

The cover is formed separately from the body, and the ripping-wire, previously made in the form of a ring with a projecting end, is inserted in the interior of bead 6, with its end projecting outwardly from the bead. The natural expansion of the ring formed by the ripping-wire tends to hold it in place in the bead of the cover during the general handling of the cover, the depth of the interior of bead 6 being sufficient to accommodate the full diameter of the ripping-wire. When the cover is to be permanently applied to the vessel, then it is placed on the body of the vessel, over which it caps easily, and, being pushed home, the lower portion of the flange fits tightly upon the tapering shoulder 2. Solder is now applied at 5 at the foot of the flange, thus permanently securing the cover to the body, a drop of solder at the same time being applied to projecting end 8 of the ripping-wire where it comes out of the bead, thus securing the wire and securing air-tight nose at the point where it projects from the bead.

When the vessel is to be opened, the ripping-tool 9 is applied to the projecting end 8 of the ripping-wire and the tool is turned so as to roll the wire up on the stem of the tool, the axis of the stem of the tool being parallel with the body of the vessel, so that as the winding takes place the stem of the tool rolls around on the circular track formed by the bead, the ripping-wire cutting its way through the bead and removing the peripheral portion of the bead and severing the cover at an intermediate point in the depth of the flange. The cover may now be removed, leaving the vessel open and with a smooth unmarred rim, adapting the vessel for use as a paint-bucket. The cover thus removed may be at any time temporarily employed in closing the vessel, the upper portion of the flange capping freely over the rim of the body and the periphery of depression 11 fitting snugly within the false wiring of the rim and preventing liquid contents of the can from escaping through the free space formed by the loose-fitting of the upper portion of the flange of the cover upon the rim. The operation of the ripping-Wire is such, as before stated, as to tear away and remove the peripheral portion of bead 6, the result being that when the severed cover is replaced upon F the can it may, so far as the flange is concerned, fit closer down upon the rim than it did before, thus allowing the periphery of depression 11 to be brought snugly home Within the rim of the body.

I claim as my invention- The combination of a vessel having an in- Wardly-turned rim and an outward swell below the rim, a cap or cover having a top depression and an exterior annular semicircular ridge fitting the inwardly-turned rim, the vertical deep flange of said cover extending downwardly into contact with said outward swell and being provided with an intermediate rib and counter-depression, and a ripping-wire having an end projecting through a hole in the flange and its body bearing expansibly against the walls of said counterdepression, whereby the said wire is held securely in said depression during the operations preliminary to sealin GEORGE KoKERMANN.
