JAMESH. BRECKENRIDGE, OF MERIDEN, CONNECTICUT..

IMPROVED CAP FOR OIL-CANS.

Specification forming part of' Letters Patent No. 31,866, dated April 2, 1861. n

To @ZZ whom it may concern.-

Beit known that I, J. H. BRECKENRIDGE, ot' the town of Meriden, in the county of New Haven and State of Connecticut, haveinvented a new and Improved Cap for Cans, Sto.; andi I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had to the annexed drawing, making a part of this specification, and to the lettersof reference marked thereon.

This cap pertains to that class which are secured to the can by means of lugs or projections upon the neck of the can. The common method is either to have the cap made of such a thickness that suitable cam-shaped or bayonet-formed recesses may becut upon the interior ofthe. cap to fit the lugs, or if the cap is made thin ofsheet metal, then the sides are cut through into the bayonet shape. The first method is objectionable, because the whole cap `must be made thick, heavy, and clumsy, While the formation of the grooves is difficult, consumes much time, and is expensive. The second method is also objectionable, on account ot' the cost and difficulty of properly cutting out the metal, and also because it renders the cap weak in consequence ot' having its sides or band divided. Y

My invention consists of an improved article of man ufacture-viz. a sheet-m etal cau-cap having a portion of its exteriorsurface raised into the form of a hollow groove or groovesto receive the lugs, as will be hereinafter shown and described. y p

In the drawing, Ashows one of my improved caps in perspective and partially upturned, 2 indicating the raised groove for receiving the lugs.

`D shows the' neck of the can, lindicating the 1ugs,which tit into the grooves 2.

F is a side elevation of my improved cap, having a portion of its surface raised, so as to form the hollow groove 2, as shown. When desired, a spring, B, may be placed within the head ofthe cap, as shown at E. A disk of cork, C,is then placed upon the spring withinthe cap. Vhen a cap thus provided is placed upon the can, the edge thereof comes in Contact with the cork, and a. tight joint is formed. Any other elastic material may be substituted for the. I

spring and cork. i

My improved cap is made wholly of sheet metal by means of dies of proper form. j These caps are produced with great rapidity and very cheaply. The sheets or blanks are fed between the dies, which then move and at a single blow form the cap complete. All filing, cutting, andiitting are thus saved, no stock is wasted, and the time of Workmen is greatly economized. i

My improved cap is much stronger than the open-grooved or cut caps, because in my improvement the band of the cap remains entire. lFor the same reason -it is also much more convenient in placing upon or removing from the can. There are no sharp corners to abrade the ngers. Y j l Having thus described my invention, I claim and desire to secure by Letters lPatent as an improved article of manufacture- A sheetmetal can-cap havinga portion ot" its exterior surface. raised and formed into a groove of the form herein shown and described, for the purposesset forth.
