SH EET-METAL CAP.
SPECIFICATION forming part of Letters Patent No. 331,999, dated December 8, 1885.
Application filed April 24, 1885.
To all whom it may concern.-
Be it known that I, FRANK WV. PER-RY, a citizen of the United States, andaresident of Philadelphia, Pennsylvania, haveinvented certain Improvements in Sheet-Metal Caps, of which the following is a specification.
My invention consists of an improvement in sheet-metal caps for oil and'other cans, and in the manner of securing the connecting-chain thereto, as fully described and claimed hereinafter.
In the accompanying drawings, Figure 1 is an enlarged sectional perspective view of my improvement. Fig. 2 is a perspective View showing the cap in place, and Fig. 3 is a side view showing the cap unscrewed from the neck of the can or jar.
In the drawings I have illustrated the cap as applied to an ordinary sheet-metal oil-can, although it will be understood that my invention is applicable to various styles of cans, jars, or other receptacles.
A represents part of the body of the can, which has the usual threaded or screw neck or top, A, and B is the cap, which is come spondingly th readed,so as to be adapted to the screw thereon and form a close joint. It is usual to provide the screw-caps with a connecting-chain,D, one end of which is connected at (Z to the body of the can or jar, while One method of making this connection with the cap has been to use a rivet, which is passed through an eye on the chain and through an opening in the topof the cap; but this is objectionable, principally on account of the consequent liability to leak at that point. To
overcome this objection and to provide a con- .Serial No. 163,314. No model.)
nection which will be at the sametime simple and cheap, I provide the chain with a ring,d which I prefer to make ofstamped sheet metal, as shown in the drawings, although it may be made of wire, and I spin or draw upon the center of the cap a boss or projection, b, of a size to about fit the opening in the ring d. After the ring has been passed over this boss or projection, the latter is pressed downward, so as to press its upper projecting edge slightly over the inner edge of the ring (2, thus forming a lip to hold the latter in place,while at the same time allowing the ring to be freely rotated on the boss. By this means the securing-chain D is well but simply attached to the cap,while the latter can be freely turned so as to be screwed onto or off the neck A of the receptacle without twisting the chain D.
I claim as my invention-- 1. The combination of a receptacle and its sheet-metal cap with a securing-chain having aring, d, said cap having a projection, b,with its outer edge pressed down onto the ring, substantially as set forth.
2. A receptacle having a securing-chain attached thereto, provided with a sheet-metal ring, d, at its end, in combination with a screw-cap having a central projection, b,with its upper edge bent over said sheet-metal ring, as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
