MJHUTO-LITNQWASHINFIUNDC UNITED STATES PATENT OFFICE.

JOHN PETER ANDERSON, OF EW HAVEN, OONNEOTIOUT.'

CAN-OPENER.

SPECIFICATION forming part of Letters Patent No. 558, 546, dated April 21, 1896.

Application filed December 5, 1896. Serial No. 571,173. (No model.)

' a citizen of Sweden, residing at New Haven,

in the county of New Haven and State of Connecticut, have invented a new and useful Gan-Opener, Of-which the following is a specification.

My invention relates to improvements in can-openers in which a movable knife or cutter operates in conjunction with a fixed pivot; and the objects of my improvements are, first, to facilitate the opening of tin cans; second, to improve the appearance of such openings when made, and, third, to avoid the danger of injury to the hands of the Operator. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure l is a general view of the apparatus seen from the front. Fig. 2 is a side view of the movable part of the apparatus, and Fig. 3 is a top view of said movable parts.

Similar letters refer to similar parts throughout the several views.

A is a rod or bar partly round, but fiat on top, to receive the thumb-screw G.

B is a neck or pivot, and O is a point or keeper used for puncturing the center of the desired opening and next for keeping the neck B in the hole so made when the apparatus is used.

D is a sleeve sliding on the bar A. E is a shoe or guide keeping the apparatus in proper position. F is the knife or cutter. The parts D, E, and F are made in one entire piece, this piece being movable on the bar A and fixed, when in the desired position, by the thumbscrew G.

The parts A, B, and O are one entire piece fixed in any suitable handle, the handle H, with the ring I, (shown on the drawings,) forming no part of my invention.

To use this can-opener, push the point 0 through the tin in the center of the desired opening and drive the neck B into said opening, leaving C under the tin to be cut. Next push the knife F through the tin and draw the handle toward you, letting the shoe E slide on the tin. v

It will be observed that the knife F is notched, as shown in Fig. 2, and this notched knife, in cooperation with the shoe E, prevents altogether any rotation of the handle-bar A and corrects any tendency of the knife to slip out of the out.

hat I claim, and desire to secure by Letters Patent, is-

A combination in a can-opener, of the handle-bar A, having point C and neck B, with a sliding sleeve D provided with the laterallyextending shoe E and notched knife F, substantially as and for the purposes described.

JOHN PETER ANDERSON.
