Application filed. November k3, 1919. Serialv No. 335,351.

To all whom t may concern: y

.Be it known thatL'EUeENE O. MURMANN,

Glendale, in the county of Los Angeles and State of California, have invented new and useful Improvements in Can-Openers, of which the following is a specification.

It is the principal object of this invention to provide a can opener which will cut downwardly,

inwardly. It is another object of this invention to provide a can opener which willV and will oper- It is a further object of this invention to provide a can opener which has a fulcrum'that may underlie the lid adj acent the portion which is cut, so that cans having little or no lip on the outside of the can adjacent the cover It is a still further object to provide a can opener of the class described with the can.

rIhese objects will be more fully .understood, as will also other objects and corresponding accomplishments of my invention from the following detailed description of an embodiment thereof. For the purpose of this description reference is had to the accompanyingI drawing, in which z` Figure 1 is an elevation of a can opener as seen from the knife blade side; Fig. 2 is afragmentary elevation looking at the can opener from the guide side; Fig. 3 is a front elevation of the opener inserted in a can, a portion of the can being shown in section; Fig. 4 is a fragmentary plan view of the out close to the edge of a can opener; and F ig. 5 is an elevation of the` opener inserted in a can, a portion of the can being shown in section. I

Referring more particularly to the drawing, 6 indicates a handle, preferably of wood, in which is mounted a shank 7. Secured to one side of the shank 7 is a knife blade 8, and secured to the shank upon the opposite side parallel tothe knife bladeis a guide 9. The guide and knife are oonveniently secured to the shank by means of rivets 10.

The guide 9, as shown herein is somewhat in the form of a triangle with one apex directed ldownwardly away vfrom the shank. The rear edge adjacent the lower apex is warped, as indicated by 11 in Figs. 2 and 3 so as to conform to the curved surface of thereby forcing the cut edge means to flatten the cut edge against the outside of the can. Theknife blade is in the general form of a hook with the point thereof projectingV Y the can.' The guide is intended to overhang form to the curved shape of the can. The

roof of the'mouth of the hook has al knifev edge'l3l formedthereon. The rear of the knife blade has a tail 14 which is warped for the purpose of crowding and bending the cut edge against the can.

. In order to cut the lid of a can, the opener is disposed with the penetrating tip resting upon the lid and the handle in anupright position. The tip must be disposed close to the edge so that the guide 9 may be forced over theside of the can as shown in Fig. 3. The tip is then pressed downwardly to penetrate the can. The handle is then tilted so that the opener is in the position shown in Figs. 3 and 5; A cut is made by forcing the handle downwardly toward horizontalposition. 'Ihe knife edge cuts downwardly, the rounded edge of the point of the hook serving as a fulcrum underneath the lid ofthe can, being warped at the tip, the latter engages the lid inside of the vline of severance.

isforced flat against the can by means of they This tail 14. The can is left with la smooth up- Y per edge so that there is no danger of the operator cutting himself. V What I claim is Y 1. A can opener comprising a handle having a blade securedtheretmsaid blade being of hook form with the point thereof projecting forwardly of the mouth to provide a fulcrumand having a knife edge formed on the roof of said mouth.

v 2. A can opener comprising a handle, a
