To all whom it may concern:

Be it known that I, JOHN S. WILLIAMSON, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Can-Openers, of which .the following is a specification.

This invention relates to can openers, and its object is to provide a device for use in establishments where canned-food is used and where the cans may be (guickly and sat isfactorily opened without aniaging their contents, as will be more fully explained in the following specification, set forth in the claims and illustrated in the drawings, wherein Figure 1 is a front view of the opener with the can shown in dotted lines. Fig. 2 is a side view of the same. Fig. 3 is a plan view.

The opener comprises an upright 5, having at its lower end a aw 6, to be fitted on the edge of a table an clamped to same by thumb screw 7. The upright carries the adjustable segments 8 having serrated faces to come in contact with one side of the can and create sufficient friction to prevent it from being turned. This face may be made of rubber or similar material to more effectually hold the can if desired and the can is gripped and held in place against these segments by means of a flexible band 9 of wire or similar material passing through guides 10 and terminating in handles 11 by which the band is operated.

At the upper end of the upright 5 is an over-hanging arm 12having at its outer end a perforation through which passes a stem 13 which carries at its lower end the head 14 with the pin 15 in its lowerside. Through a slot in the head 14 passes a slide 16 to which is' hinged a lever 17 carrying a knife 18. The pin 15 is adapted to be pushed down into the upper end of the can as shown in Fig. 1, and the knife 18 will then be just below the up er edge of the can when it is forced inwar fend the-lever 17 with the'slide 16 is swept around the can cutting the to loose almost the entire distance around the can itself.

The segments 8 are right 5 and may be adapted to provide :for different diameters of cans. They are forced outward and retained in, position by the adjustable the upthumb screw 19 which plays through the up right 5, and the guide-ways 10 are connected by means of pins 20 which may be arranged at various oints in order to draw the band. 9 so as to c amp it around the can according to the size of can to be operated on.

The operation of this can opener is rapid and satisfactory and it is obvious that the parts may be modified or otherwise arranged without departin from the essential foa tures shown and ascribed.

What I claim as new and desire to secure by Letters Patent is,-

1. A can opener comprising an upright having an integral arm formed on the upper endthereof and a clamp formed on the lower endvthereof, a stem mounted to depend from the said arm, a slotted head mounted on the lower end of the said stem, the said slotted head being carried by the said stem, a depending pin on the said stem and adapted to engage the top of the can at a central point, a handle, a cutting knife carried by the said handle, a slide mounted to operate laterally in thcsaid slotted head, the said slide having the said handle pivoted thereto, a clamping member comprising a flexible band of a shape to conform to the periphcry of cans of various diameters, the free ends of the said band forming arms cxtending laterally and terminating in handles, a guide mounted on the said upright and adapted to receive the laterally extending arms and locking pins adapted to project through one of a series of apertures in the said guide to hold the said arms in adjusted position.

2. A can opener comprising an'upright having an inte 'al arm formed on the upper end thereof an? a clamp formed on the lower end thereof to receive a base, a stem mounted to depend from the said arm, a slotted head mounted on the said stem, a slide carried by the said slotted head, a handle pivotally connected to the outer end of the said slide, a knife carried by the said handle, a clamping member comprising a band, said band being shaped to conform to the periphery of cans of various diameters, the free ends of the said band-forming arms extending laterally and terminating-in handles, the said arms being projected through a ide mounted on thesaid 1 P- right the said guide being provided with apertures to receive locking pins for holding In testimon whereof I affix my signature tlgla said armshin adjusted pzsfition, adjust in presence 0 two witnesses.
