JAMES OHISHOLM, OF FORT LISCUM, ALASKA TERRITORY.

CAN-OPENER.

SPECIFICATION forming part of LettersPatent No. 707,207, dated August l19, 1902. Application led January 20, 1902. Serial No. 90,-526. (No `model.)

T0 all whom t may concern: V

Be it known that I, JAMES.CHIsHOLM,a citizen of theUnited States, at present stationedl at Fort Liscum, in the Territory of Alaska,

quickly and easily opened and all danger ofv cutting the hand during such operation entirely avoided. 1 Another object is to provide a can-opene in which the cutting-blade can be quickly.`

and easily adjusted to out adjacent to or remote from the edge of the can, thereby cutting either a large or small opening, as preferred; and another object is to provide a can-opener in which the cutting-blade can be adjusted with reference to the guidin'gporf.

tion of the cutter, so that the device can be used for opening all sizes of cans.

With these and various other objects in view Vthe invention consists of the novel features of construction and combination hereinafter fully described, and pointed out in the claims.

In the drawings forming apart of this specification, Figure l is a perspective View illustrating the application of my invention. Fig. 2 is a perspective view of the device as viewed from the under side. Fig. 3 is a detail-bottom plan view, and Fig. 4 is a detail sectional view illustrating the blade-adj usting mechanism.

In carrying out my inventionl employ a handle A,Which is preferably formed integral with the body portion B, which is in the nature of a thick plate, the edge B of which is curved and provided With-an undercut shoulder B2, the edge B and shoulder B2'being1 constructed upon different curves and meeting at the point or end B2. The body is formed with an extension or projection O at the side opposite the point or end B2, said projection or extension having'an oblique slot C' produced therein and in which works the shank D of the cutting-blade D, said -shank having a head D2, Whichrests upon the top of the extension, being wider than the slot. An adjustingscrew E passes transtudinally within theoblique slot, the inner end being journaled at the end of said slot, and a collar E2 is fastened upon the screw and adapted to bear against the opposite end of the slot for the purpose of holding the screw in itsrproper longitudinal position, so that by turning the head' E in either direction the blade can be adjusted as desired.- The undercut shoulder B2 is produced upon a slight inclination, as clearly illustrated in Fig. 4, in order to prevent slipping during the operation of the device.

In operation the edge of the can is placed again/st the undercut shoulder B2 and the blade D forced' down through the top of the can, and by pushing uponl the handle and forcing the body around the edge of the can the cutting-blade is caused to travel around, l

cutting the top in a circular line adjacent to the edge of the can. Theundercut shoulder B2 is curved in such a manner that it will snugly't nearly all cans now in common use, and by adjustingthe blade` in or out the device can be made suitable for operation upon all sizes of cans.

Having thus fully described .my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. A can-opener having a body provided with av curved undercut shoulder, va slotted extension orprojection, the cutting-,blade adjustably arranged in said I slotted extension, and an operating-handle connected to the body, as set forth.

2. A can-opener comprising a body portion having a curved undercut shoulder, an 0bliquely-slotted extension or projection, a cutting-blade having its shank arranged in said slotted extension, and means arranged within the slot and connected to the shank for the purpose of adjusting the blade, as set forth.

3. A cani-opener comprising a body portion having a curved edge and a curved undercut shoulder, the obliquelyslotted extension or projection, the cuttting -blade having its shank located in said slot, the adjustingscrew workingin the slot'aud passing through the shank and theoperating-handle integral with the body portion,. substantially asset forth.
