JOHN ARTHUR ROBINSON, OF OTTAWA, AND MILTON LORNE ROBINSON, O15 ARN'EBIOE,

ONTARIO, CANADA.

CAN-OPENER.

Specification of Letters Patent.

Patented Aug. at, rare.

Application filed December 6, 1916. Serial No. 135,481.

of Ontario, in the Dominion of Canada,

plumber, have invented new and useful Improvements in Can-Openers, and do hereby declare that the following is a full, clear, and exact description of the same.

Our invention relates to improvements in can-openers, in which the can-opener has two levers, the one being straight is provided with a piercing point at its extremity, and the opposite lever has a curved jaw, at the extreme end of which is located a circular knife, with a guide directly over said knife. The levers are operated on a pivot.

The invention is illustrated in the accompanying drawing, in which Figure (l) is a top view of the can-opener, showing how the different parts are shaped, and where they are Located.

Fig. (2) is a side view of the can-opener, showing where the circular knife is located, also to show how the cork-screw is made to form the pivot for the levers.

Fig. (3) is an end view showing the guide which rides around on the top of the can to keep the circular knife in its proper course, also showing how the cork-screw is held in position when not in use.

Similar figures refer. to similar parts throughout the several views.

4 and 5 represent two levers, one straight and one curved, pivoted at 10. The straight lever 4; carries a piercing point 8' offset from one of its ends secured thereto by'a riveted head 11. The curved lever 5 has an extremity bent over upon itself and 1 represents a knife journaled in said bent over portion by means of a rivet 9 and 2 indicates a guide carried b said rivet. The pivot 10 is extended and ormed into a corkscrew 6. The curved lever 5 is providedwith a bottle opener 3 and a concaved portion 7. 13 represents the top of a can to be opened.

The piercing point (8) is inserted into the center of the can, and pressed downward until the levers (4) and (5) are in a horizontal position, placing guide (2) on top of the outer edge of said can, with the cutting edge of knife (1) pressing'against the outer upright surface at a distance of about fath of an inch from its top, and forced through the tin by the levers (4) and (5) being drawn together and moved horizontally in a circle, making a vent in said surface until the top of the can is severed from the body of said can.

Bottle cap remover (3) is used to remove metallic caps from the tops of bottles by placing the point underneath the edge of said caps and prying upward.

Cork-screw (6) is used for taking corks from bottles by inserting said cork-screw into the cork to be drawn, by a righthand circular motion until said corkscrew has sufficient hold and is to be drawn upward. The 'end of cork-screw (6) also forms the pivot at (10) for levers (4) and (5).

We are aware that prior to our invention can-openers have been made with circular knives and piercing points. We therefore do notclaim such a combination broadly; but

What we do claim as our invention and desire to secure by Letters Patent, is-- A can-opener comprising a pair of levers pivoted together intermediate of the length, one of said levers having a straight end, the other of said levers having a curved end, the end of the lever having a curved end being formed with a U-shaped extension, a pivot pin extending transversely across the U-shaped extension, a rotary cutting knife mounted on the pivot pin, a guide on the top of the U-shaped extension adapted to engage the edge of the can and a piercing point on the extremity of the lever having a straight end, substantially 'as and for the purpose specified.
