Specification of Letters Patent.

Patented May 5, 1908.

Application filed January 28, 1903. Serial 110413019.

To altwhom it may concern:

Be it known that I, JOHN ZANDER, a citizen of the United States, residing at Chicago,

outer slip-cover, and a blade adjacentto the fulcrum-but lying in a planesubstantially at right angles thereto, to enter beneath the .flange of the slip-cover and raise and detach this cover from the fixed head, when the tool is pulled upward by the handle at its outer en The tool also has a lug, extending from the bar on the side opposite the coverdetaching blade, which l-ug cooperates .with the fulcrum in removing or replacing the screw-cover which closes the opening in the s so fixed head. I y

Referring to the accompanying drawings, Figural is a pers ective view of the tool; Fig. 2 is a sect ona view of the upper end of a. carbid-can, having an inner fixed head and .screw cover and an outer slip-cover; Fig. 3 is .a perspective view of the upper end of th s carbid-c'an, with the slip-cover in place,

showing the tool in position to remove this cover; and Fig. 4 is a plan view of the upper end of the carbid-can, with the slip-cover removed, showing the tool in screw the screw-cover.-

' lThe'can-opener; shown in Fig. 1, consists of a rigid bar 1, preferably a fiat strip of tempered steel, the .end 2 of which is forged position to unround and bent laterally to provide a terminal fulcrum 3. Adjacent to the round end 2 is the cover-detaching blade 4, made by forging the oflset end of the bar 1 to a sharp edge. f From the sideof the bar oppo- I site to the blade 4, extends a lug 5 having a s uared' end 6, which cooperates with the crum 3 in removing or "replacirig the screw-cover. The outer end of the bar may be provided with a Wooden handle 7.

The carbid-can, for the opening of which this tool isspecially designed, is shown in Figs. 2, 3 and 4. This can comprises a body E 8 having an inner fixed head 9 and an outer slip-cover 10; The fixed head has a central marginally-threaded opening 11 which is closed by a'screw-cover 12. This cover has a diametral piece 13 which serves as a handle in screwing the cover out or in. The slip cover 10 has a marginal flange 14 which is slightly crimped beneath the edge of the fixed head 9. In employing the tool to open .this can, the fulcrum 3 is placed on the upper edge, of the slip-coverlO, as shown in Fig. 3, and the blade 4 is inserted beneath the flange of this cover. By raising the handle 7 of the tool, the flange is detached from.

thetop of-the can at one point. By shiftingthe fulcrum 3 .to several points, the cover may be easily and quickly removed.

The tool may then be used to unscrew the cover 12, by applying it to the cover in the position shown by full lines in Fig. 4, with the fulcrum 3 resting against one end of the cover-handle 13 and thelug 5 resting against the vertical threaded edge of the cover. The tool is then rotated in a contraclock-wise direction. To replace the screw-cover the tool is applied in the position shown by dotted lines'in Fig. 4, the fulcrum 3 then bearing against the opposite side of the cover handle 13 and being rotated in aclock-wise direction.

I claim l. A can-opener, consisting of a bar having a lateral end fulcrum and an intermediate cover-detaching blade, said fulcrum and blade situate in different planes.

2. A can-opener, consisting of a bar having a lateral end fulcrum, a cover-detaching blade adjacent to said fulcrum, and a lug re 'mote from said fulcrum, said blade and lug being oppositely disposed.

Intestnnony whereof, I allix my signature in presence of two XVIUIGSSBS.
