can OPENER.

Application mea January 4, leer. sei-iai No. 158,952.

This invention relates to can openers and l has for its object toprovide a Adevice that can be conveniently handled in the household foropening tin cans of any size and shape.

l/th this object in View my invention consists in the novel construction, combination andarrangement of parts as will be hereinafter more fully described and defined iii the appended claims. Y

In the accompanying drawing which constitutes part of this specification and in which similar reference characters denote corresponding parts Fig. 1 is a front elevation of my device; Fig. 2 a` side elevation thereof; Fig. 3' a cross-section online 3 3 of Fig. 2 and Fig. 4 a. front elevation of a modified form of construction.

The device comprises a vrigid upright supportlO having a flat front face and which at its lower end'is U shaped as at 101. The" lowerV forwardly project-ing part of said .id shaped part carries a vertically working clamping bolt 11 whereby the support lcan be conveniently and easily clamped to a table or the like. The upper portion of the support is centrally and longitudinally slotted as at .10n to adjustably and pivotally support f a cutter or knife 12. This-cutter or knife consists of a comparatively long arm or handle which at its lower end is formed with laterally projecting curved wingsV 121 the outer circumferential edges 122 of which are sharpened to constitute blades. rlhe lower` opened, is placed on the table T close to the support 10 and the knife adjusted in the support so that when the arms are swung to vand fro like a pendulum inopposite directions around its pivot the two blades will alternately be forced through the top of the can and lproduce incisions therein. During this cutting operation the can is guided and fed by hand.

y In the modified construction shown in Fig. 4, the knife has a single blade 12G the rcutting edge ofwhich is formed around the curved bottom edge of the wing as at 12T.v The opposite wing 12s is adapted to serve as a grip per and vto this end bottom edge is roughened or formed with ridges as at 129.

this modified knife is arranged eccentric-ally as at 131 so that as the arm 12a is swung to theleft (according to F ig. t) the blade 127 will first pierce the top of the can with its tip 1210 andthen 'produce an incision in the forward direction. TWhen the arinis swung inztliereverse direction the gripper12i will engage tliejcan and feed it rearwai'dlyor toward the blade. f

"W hat I claim is 1. A can opener, comprising an upright support adapted to be removably attached to a table or the like and having 'acont-inuous longitudinal slot7 and a comparatively longV lever arm pivoted in said slot so as to be ad Justable therein in a continuous manner', and

formed with a curved cutting edge arrangedvv laterally of the pivotal point of saidV arm, a portion of said cutter Vbeing roughened The pivotal point of the arm 12n vformed with sev whereby in one position automatic feeding of the can being cut will result. Y

`2. A'. can opener7 comprising anfupright support adapted to be removabiy attached 'to nous longitudinal slot, a coiniiaratively `long table or` the like aiidformed with acontinlever arm pivoted in said slot so as to be adjustable therein ina continuous manner and formed with a curved cutting' edge projecting laterally relative tothe pivotal point of said a'rm,av portion o'f'said cutting edge be-` ingsei'rated toform'a can feeding means.' 3. A can opener comprising an upright support adaptedto be removably attached to a base7 and formed withalongitudinal slot, va comparatively long arm provided at'one end thereof,vwith a curved laterally eXtending cutting edge formed-.with a roughened v.

portion, said arm beingpivoted at a point intermediate its end to a pivot slidably adjustable in saidlongitudinal slot, whereby when said arm is given 'a pendulous motion about said pivot7 alternate cutting and automatic feeding of the can tofbe cut will result.

4C. A can lopener comprising an upright support adapted to be removably attachedfto a base7 a comparatively long'arm provided ing cutting edge and automatic feeding means on sadentter Wherely alternate'eutting and: automatlc fe'edlvng of tlecfmltobe `cui: Will result.

5. A can opener comprising imT upright support adapted to be removably attached to a base, an arm :Ldjustably pivoted the'reo lani S provided at oneend thereof with a laterally GUSTAV MEIER.
