Sheet-Metal Can.
Patented Ang. 31,1875.

JOHN HERGET, OF ST. LOUIS, MISSOURI.
IMPROVEMENT IN SHEET-METAL CANS.l
Speeieation forming part of Letters Patent No. 167,172, dated August 31, 1875 application filed May 1, 1875.
To all 'whom it may concern:
Be it known that I, JOHN HERGET, of St. Louis, county of St. Louis and State of Missouri, have invented a new and useful Improved Joint for Metal Cans, ot' which the following is a specication:
This invention relates to cans for holding pigments, white lead, lard, and vother substances, as well as fluids, that require an airtight joint.
My invention consists in uniting the top, bottom, and sides ot' eans by means ofthe peouliarjoint, as will now more fully appear.
Ot' the drawing, Figure lis my invention in section. Fig. 2 represents my invention in enlarged detail view.
A is the body or sides ofthe can. The sides I form to have an inwardly-projecting bead, a. (See figures.) B are the heads or top and bottom of the can. The new feature I provide the heads B with is the indenting edge b. (See figures.) The heads I next tit in the body A, so that the edge b shall engage the bead a. It is this joining'of b with a that I rely upon in forming an air-tight joint. Therefore, in closing this joint, the edge b is virtually indented into the bead a, and as shown in the figures. The joint is completed by the edges a of the sides being made to overlap the edge b, as illustrated. This lapping' ofthe edge a being inward, it retains and holds the edge b on the bead.
As apparent, this joint can be readily closed and readily opened, and this done so that the can can be reused. The joint is most strong and durable, from the fact of the edges being short, and the shaped or stamped heads directing Whatever pressure or Weight they sustain in a direction that further tightens the joint.
In oase of some kinds of iluid matter, if neeessary, the edge a can be soldered where it joins the heads.
The heads of cans formed to have an indent- 4ing edge, b, as herein shown and described, in
combination with the body of cans formed with beads a and overlapping edge a', by means whereof an air-tight and secure joint is had, substantially as described and shown.
In testimony of said invention I have hereunto set my hand.
JOHN HERGET.
