W51 invention is toprovide a can cuttin device of this character t ture and very simple of operation, the same consistin of fewparts and these soco-related asto re uce the ment to a minimum.

-IYWith the foregoin and other objects in novel form, combination and arrangement of parts hereinafter more fullydescribed, s 'own in the accompanying drawings and claimed. s i In the accompanying 'drawin s iormin part of this applicatlon and in which like re erence characters indicate corresponding parts:

y" Figure 1 1s a side elevation of my impr oved can opening device. a a

Figure 2 1s a top plan view thereof.

. Figure 3 isa fragmentary inner side felevation.

j Figure 4 is a outer sideelevation, and

Figure 5 1s a perspective of the-lower'end' of thereciprocatory cutter carrying bar.

Now having particular referenceto the 5 drawings, my novel can cutting. device consists of a suitable base board 5 upon which is arranged transversely adjacent one end thereoi an L-bar 6 to which is securedat a point intermediate the ends thereof vertically extending posts 7 upon the back side of which is arrangedfor rotation a train of high aeed geanng' 8 then permost'large gear ing equipped with a crank handle} while the lowermost gear-4s arranged possibility of disarrange-v .view as the nature 0 .the invention will bebetter understood, the" same comprises the- One of the most important objectsof the at is inexpensive o manufacis rovided;with a depending upper end of the ofiset portion 14is a cutter extending fiat ba r guide 13 through which is I mounted for vertical reciprocation a flat .bar 14. Shdably arranged upon the bar 14 be= neath the guide 13 is a sleeve 15 that may be secured thereto .in predetermined :adjusted positions by reason of. a set screw 16. jPivoted to the back sideof. this sleeve 15 as at 17 isthe upper end of a connecting rod 18, the

lower end of which i's eccentrically pivoted as at 19 to the; frontYfaceof-the fly wheel 111' and ata point but 'slightly ofi'set as clearly I disclosed in Figure .3. i The lower end of the reciprocatory bar 14:

- and rearwardl'y 0 set extension 14., while Zdetachably secured to the lower end of the bar directly-above the blade 20, the side edges of which converge inwardly toward the lower end so that t e same willeasily pass throu h the'lid ofa can. 1

- The invention flirt er consists'of a transversely e'xtendin bar 21 arranged upon the base 5 in front ,0 the fly wheel 11 and against which a'can A-is forced I disposed upon the base 5 at substantially-the center thereof. In order to.prevent';trans-.

verse movement of the can upon the '.there is provided for coo ation withth'e bar 21 a metallic fork 22,- t e apex 'ofwhich'is remote from the-bar 21 and provided with a- 'when-thesameis plate' 23 formed with alongitudinal slot 24 so I' that the same maybe adjustably secured to;

the'base 5 by reason ofa bolt and wing nut connection 25.

Obviously, in actualpractice the can. A-is arranged beneath the cutter' 20 in raised condition and the can forced againstthe bar 21- and the ofiset extension 14' of the reciproeatery bar 14. The screw 16 of thesleeve 15 is released so that the bar 14 may be properlyadjusted so that when the bar 14 is in its fully-H raised position, the cutter 20 will be above the e 'lid' of the can. The screw 16 is then tightened af er, which the handle 9 is to-be rotated for reci rocating-the'cutter bar 14whieh will cause .t erapid projection of the cutter 20 into the lidof -the can A, said cutter being p t -Me d of a shaft 10 that is mounted for rotation edge s the post-7 theifrontend of;

guided through thelid at a of thecanA by-the o v setextensidnl t ofsaidbarli L int adjacent the.

Obviously if it is desired to remove the lid of a square or rectangular shaped can the fork 22 is slid out of the way and during the reciprocation of the cutter bar the can is moved transversely across the base 5 in contact with the outer edge of the guide bar 21.

In view of the foregoing description when considered in conjunction with the accompanying claims it will at once be apparent that I have provided a highly novel, simple and extremely efficient can opening device that is well adapted for all the purposes heretofore designated, even though I have herein shown and described the invention as consisting of certain detailed structural elements it is nevertheless to be understood thatsome changes may be made therein without affecting the spirit and scope of the appended claims.

Having thus described the invention, what I claim as new is 1. In a can opening device of the character described, a rigidly mounted vertically extending post, a train of high speed gearing associated with the post, means whereby the gearing may be rotated, a fly wheel associated with one gear of the train, a vertically extending guide sleeve associated with the post adjacent its upper end and at the same sideof the post as said fly wheel, a bar mounted for vertical reciprocatory movement through said sleeve, a cutting knife arranged upon the lower end of the bar and adapted to be engaged through the lid of a can arranged beneath said bar and a driving connection between the fly wheel and said reciprocatory bar.

2. In a can opening device of the character described, a rigidly mounted vertically extending post, a train of high speed gearing associated with the post, means whereby the gearing may be rotated, a fly wheel associated with one gear of the train, a vertically extending guide sleeve associated with the post adjacent its upper end and at the same side of the post as the fly wheel, a bar mounted for vertical reciprocatory movement through said sleeve, a cutting knife arranged upon the lower end of the bar,and adapted to be en- 1 gaged through the lid of a canarranged beneath said bar and a driving connection between the flywheel and said reciprocatory bar, and means whereby a can may be secured against lateral or longitudinal movement beneath said knife.

3. In a can opening device of the character described, a rigidly mounted vertically extending post, a train of high speed gearing associated with the post, means whereby the gearing may be rotated, a fly wheel associated with one gear of the train, a vertically extending guide sleeve associated with the post adjacent its upper end and at the same side of the post as the fly Wheel, a bar mounted for vertical reciprocatory movement through said sleeve, a cutting knife arranged upon the lower end of the bar and adapted to be engaged through the lid of a can arranged beneath said bar'and a driving connection between the fly wheel and said reciprocatory bar, means whereby a can may be secured against lateral or longitudinal movement beneath said knife, said means consisting of a bar arranged transversely beneath the knife and against which the can is to be engaged, and a clamping form arranged beneath the knife at the outer edge of said bar for engaging the opposite side of said can.

4. In a can opening device of the character described, a rigidly mounted vertically extending post, a train of high speed gearing associated with the post, means whereby the gearing may be rotated, a fly wheel associated with one gear of the train, a vertically extending guide sleeve associated with the post adjacent its upper end and at the same side of the post as the fly wheel, a bar mounted for vertical reciprocatory movement through said sleeve, a cutting knife arranged upon the lower end of the bar and adapted to be engaged through the lid of a can arranged beneath said bar and a driving connection between the fly wheel and said reciprocatory bar, means whereby a can may be secured against lateral or longitudinal movement beneath said knife, and an inwardly offset ex tension arranged upon the lower end of the bar and projecting beyond the cutting end of the knife for engagement at the outer surface of the can for guidin the knife through the top adjacent the end ody.

In testimony whereof I atfix my signature.

IRVING ANDERSON.
