UNITED STATES PATENT OFFICE.

JESSE S. MOORE AND JEROME MEYER, OF NEW YORK, N. Y.

CAN" OPENER.

Application filed. April 29, 1922. Serial No. 557,334.

T 0 all whom it may concern:

Be it known that we, Jnssn S. MOORE and .Tnaoarn MEYER, citizens of the United States, and residents of New York, county and State of New York, have invented certain new and useful Improvements in Can Openers, of which the following is a specification.

This invention relates to a type of can opener in which acircular or semi-circular opening is out into the top of the can by a single operative movement of the device. The object of the invention is to provide a can opener having such characteristic and of such simplicity that it may be manufactured at very small cost, while at the same time it may be positive in its action.

The invention will be understood by reference to the accompanying drawings, in which- Fig. 1 comprises a side elevation of the device, and

Fig. 2 is a plan view of the same.

Fig. 3 is an end elevation of the can opener.

Fig. 4; is a perspective view of the device, illustrating the manner in which the top" and side of the can is penetrated by the curved prong, thus affording the latter two fulcrum points.

By reference to the drawings, it will be seen that the device consists of an arm or hand lever B formed at its outer end with the downwardly curved prong A which is adapted to penetrate the top and side of the can, as shown in Fig. 4e. Overhanging prong A is a fulcrum-blade A", to adapt the device for use as an ordinary can opener. In such case the prong A serves as the knife.

The hand lever B is provided, immediately in advance of prong A, with a blade D which may be circular but which in the present instance is semi-circular. It will be noted from the drawing that the blade D has a depth gradually increasing toward the centre from each end and merging into a point C, the rear of the blade being disposed nearest the prong A.

At opposite sides the blade is formed with an angular slot so that two small wedge-like sections E of the blade may be bent inwardly for the purpose hereinafter described.

In opening a can with the device, the operator pierces the top and side wall of the can with the prong A so that the pierced walls of the can may act as a fulcrum-bearing for the hand lever. The lever may now be depressed, point C entering the can fol lowed gradually by the entire cutting edge of the blade.

Prior to the end of the cutting movement of the blade wedge-hooks E will be carried below the top of the can. However the edge of the cut-out section, temporarily displaced by the wedge-hooks will spring back over the horizontal top walls of the latter. And in the reverse movement of the device the cut-out section of the can will be elevated thereby.

It will be understood that various changes in the embodiment of the invention shown in the drawings may be made without departing from the spirit of our invention. The blade may be cast in one with the hand lever, or it may be formed separately and welded or otherwise secured to the lever. And if desired the hand lever may be permanently attached to the frame. However, the means of attachment shown and described is desirable in that the members may be very readily assembled and disassembled for packing or for cleaning after use.

What we claim and desire to secure by Letters Patent is A can opener comprising a lever arm having at its front end a forwardly projecting curved prong adapted to penetrate the top and side wall of a can to provide two spaced fulcrum points, a fulcrum-blade overhanging said prong, and a curvilinear blade carried by the lever arm, as and for the purpose described.

In testimony whereof, we have signed our names to this specification in the presence of two subscribing witnesses.

JESSE S. MOORE. JEROME MEYER.
