UNITED STATES LOUIS KOSSUTH AND CHARLES LANZA, OF GARFIELD, NEW JERSEY.

CAN OPENER.

Application filed September 22, 1927. Serial No. 221,268.

This invention relates to a can opener.

It is aimed to provide a novel construction of opener for the closures'of cans-such as those which contain white lead and other paint, in particular, since the same must be hermetically sealed and are difficult to remove.

The primary object of the invention is to provide an opener having relatively movable levers, one of which is bifurcated, and the can engaging parts of which levers are con vex or concave according to the shape of the portions of the can to be engaged thereby.

Additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating an operative embodiment.

In said drawing Figure 1 isa view of the opener in elevation;

Figure 2 is a plan view thereof;

Figure 3 is a fragmentary view in elevation showing the opener in the act of being used;

Figure 4 is a detail sectional view taken on the line l4 of Figure 1, and

Figure 5 a detail sectional view taken on the line 5 5 of Figure 3.

Referring specifically to the drawing, the

same comprises relatively movable levers 10 and 11, pivotally connected together as by a pin 12 and being adapted to be gripped at handles 13. Lever 11 has a bifurcation 14:, providing lugs 15 and 16 on opposite sides thereof, the innerwall of the lug 15 at the bifurcation being convex as shown in Figure 5 and the inner wall oft-he iug 16 at such bifurcation being concave as shown in Fi ure 5, so as to conform to the shape of the portions of the can or closure to be engaged there by. The operating end 12 of lever 10 is gen erally pointed and is concave as at 17 where it is adapted to engage against'the side of a can.

In using the device, it is applied to a can such as 18 as conventionally suggested fragmentarily by the dotted lines in Figure 3. The closure of the can at the marginal portion is received in the bifurcation 14 with the convexity of the tooth 15 fitting the con cavity of such marginalportion and the concavityof the tooth 16 fitting the convexity of such portion. At the same time, the con cavity 17 fits the side of the can and the sharpened or pointed end of the lever 10 en gages under the depending portion of the closure. When the levers 13 are moved relatively, it will be seen that the closure will be engaged and disengaged and may readily be removed.

Changes may be resorted to provided they 7 fall within the spirit and scope of the invention.

lVe claim as our invention A tool of the class describe-d con'iprising relatively movable levers, one'of said levers being. bifurcated, the corresponding portion of the other lever being concave for the purpose specified the bifurcation providing lugs on opposite sides thereof, the outermost lug being convex on its inner surface and the innermost lug being concave on its inner surface.

In testimony whereof we our signatures.
