Serial No. 484,615.

To all whom it 'may concern:

Be it known that I, JOSEPH CorLiNKY, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented new and useful Improvements in Can-Openers, of `which the following is a specification.

This invention has for its object to provide a novel form of implement for opening cans or like sheet metal packages containing goods of different kinds, said implement being of such formation as to adapt itself to cans or packages of varying sizes and shapes whether circular, oval or rectangular.

The primary purpose of the invention is the provision of a tool or implement of the character aforesaid comprising pivoted members formed of telescoping sections, one of said members being provided with a cutter and the other member having a centering point or points to fix the relative position of the stationary member when the implement is in operation.

A further purpose of the invention is to supply an implement for the purposes hercin outlined which may be cheaply and economically manufactured and comprising parts adapted to be readily assembled and easily and cheaply replaced in the event of any one of the parts becoming disabled so as to render the implement unfit for further effective service without being repaired.

In the drawings herewith a preferred embodiment of the invention is illustrated, however, it is to be understood that within the scope of the invention as claimed, various changes, in the form, proportion and minor details may be resorted to without departing from the spirit of the invention.

Referring to the accompanying drawings forming a part of the specification, Figure l is a. top plan view of a can opener embodying the invention, parts being broken away. Fig. 2 is a view similar to Fig. l as it appears from the reverse side. Fig. 3 is a transverse section on the line 3 3 of Fig. 2 looking toward the pivot pins of the members. Fig. 4 is a detail perspective view of a portion of the handle or relatively stationary member, the outer portion being broken away. Fig. 5 is a perspective view of the cutter member, the handle portion being broken away. Fig. G is a perspective view of the intermediate section of the cutter member. Fig. 7 is a transverse section on the line 7 7 of Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the saine reference characters.

The two members are designated by the reference letters A and B and are pivotally connected at one end by a pivot fastening l of any construction. Each member comprises a plurality of sections which are telescopically or slidingly related to admit of the lengthening or shortening of the members.

The member A is relatively stationary when the implement is in use and may be properly designated as the handle member and it is provided with one or more spurs or points 2. The inner section 3 of the handle member is provided at one end with a disk or hub 4 which is centrally apertured to'receive the pivot fastening l. The opposite end portion of the section S is recessed in one side as indicated at 5 to receive the cooperating section (5 which is slidably mounted therein. Longitudinal grooves 7 are formed in the walls bordering upon the recess 5 and receive lugs 8 projected laterally in opposite directions from the inner end of the section G. Grooves 9 communicate at their inner ends with the longitudinal grooves 7 and extend outward through the recessed side of the section 3 and provide passages for reception of the lugs S when assembling the sections 3 and (3. The outer ends of the longitudinal grooves 7 are closed thereby preventing outward displacement of the section G and limiting the outward movement thereof as indicated most clearly in Figs. 1 and 2. Each of the sections 3 and G is provided with a point or spur 2 which is adapted to penetrate the can or package when placing the implement in. position preliminary to operating the same to et'r'ect an opening of the can. The section has a` longitudinal slot 10 through which a thumb screw 11 or like fastening passes and which is threaded into 'the outer end of the section 3. The fastening 11 provides ready and convenient means for securing the sections 3 and (5 in an adjusted position.

The cutter member B comprises a series of sections 12, 13 and 1st having a telescoping arrangement to admit of the member automatically lengthening or shortening so that the cutter 15 may follow an irregularly shaped can or package when opening the same. The inner section 12 is similar in construction to the section 3 and is provided at'one end with a disk or hub 1G having a central opening to receive the pivot fastening 1, said section having a recess 17 in one side to receive the section 13 and having longitudinal grooves 1S in the inner walls thereof bordering upon the recess 17, said grooves being closed at their outer ends and communicating at their inner ends with lateral grooves 19 which open through the recessed side of the section 12 and provide passages for the lugs 2O projected laterally from the inner end of the section 13. The section 13 has a recess 21 in one side extending throughout the length thereof and adapted to receive the section 14. Longitudinal grooves 22 are formed in the walls of the section 13 bordering upon the recess 21 and receive lugs 23 projected laterally from the inner end of the section 14e The grooves 22 are closed at their outer ends in a manner similar to the longitudinal grooves 7 and 18 to engage with the lugs 23 and limit the outward movement of the section 14. The section 14 is adapted to be placed Within the recess :21 of the section 13 with the lugs 23 clearing the inner end of said section 13 after which the section 1st is moved outward to cause the lugs 23 to enter the grooves 22.

The cutter 15 may be of any construction and is fitted to the section 1-1 in such a manner as to admit of its replacement when broken or otherwise rendered unserviceable. A grip or handle piece 24 is tted to the outer end of the section 1% and a similar grip or handle piece is fitted to the outer end ofthe section 6.

When the component parts of the implement are assembled the tool presents the appearance substantially as illustrated in Figs. 1 and 2. lVhen it is required to open a can or sheet metal package, one. or both of the points 2 are forced into the cover or part of the can to be opened thereby fixing the position of the handle member A. The cutter 15 of the operating member B is forced through the cover of the can preferably near the outer edge thereof after which, the handle piece 24 of the cutter member B is gripped and moved so as to cause the cutter 15 to follow the cover close to the edge or side of the can, the telescoping construction of the cutter member admitting of the cutter 15 following the irregular shape of the cover and always remaining near to and following the side of the can whether the latter be round, square, oblong or of other form.

Having thus described the invention, what is claimed is 1. A can opener comprising pivotally connected members, one of said members being extensible and comprising telescoping sections, a centering point applied to one of said members, and a cutter carried by the other member at the handle end.

2. A can opener comprising pivotally connected members, both members being eXtensible and each comprising telescopically related sections, a centering point applied to one of said members, and a cutter carried by the other member at the handle end.
