A. PRIMAK Dec. 18, 1951 CAN OPENER Filed Feb. 14, 1947 INVENTOR. JDAM PA/M n Patented Dec. 18, 1951 UNITED STATES PATENT OFFICE 1 Claim.
the invention resides in the novel construction,
combination and arrangement of parts, substantially as hereinafter described, and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.
In the accompanying drawings is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.
In the drawings:
Fig. 1 represents a side elevation of a combination tool embodying the features of my invention with parts broken away and in section, as indicated by line Il of Figure 2.
Fig. 2 is a bottom plan view of the same with parts broken away to illustrate structural features.
Fig. 3 is a cross section of the tool the section being indicated by line 3--3 of Figure 1.
Fig. 4 is a rear end View of the tool looking towards its open end handle.
Referring by characters to the drawings, A indicates a hollow handle, the same being U- shaped in cross section having a top wall I and side Walls 2 and 2'. The handle carries a transversely disposed pivot rod 3 having mounted thereon a series of convenient tools or instru" ments, comprising a knife blade 4, a cork screw 5, a punch 5 and a screw driver 1, which tools, when folded, fit compactly within the hollow handle. The end of the side wall 2 is beveled to form a scraper 8 and the opposite side Wall adjacent to the open end of the handle, is folded backward upon its edge to form a can opening blade 9, which blade is extended outwardly from its companion. side wall and a clearance throat it! in the form of a slot is extended backwardly from the open end of the handle to form a clearance between the top Wall I and the adjacent face of the blade 9.
The top wall is cut away in rectangular form and the freed metal is bent upwardly and outwardly, with reference to the top wall, to form a bottlecap opening finger II.
The end of the top Wall is also folded upward- 1y to form a spur 12, which spur is associated with the finger H for convenience in lifting a cap from a bottle.
As shown, the end of the spur [2 may be tapered to a piercing point I2 for various purposes.
The pivot rod 3, which extends through the side walls of the handle, carries a rotary guide roller 9, which guide roller is utilized for abutting the body of a can when the blade 9 is functioning, to cut away the top of said can. From the foregoing description, it is apparent that the peculiar arrangement of the U-shaped handle, with its open end, provides means for forming a series of fixed tools while the handle serves as a nesting cavity for the reception or a gang of pivoted tools. 7
The button 9 may also serve as a hammer when it is desired to drive tacks or the like.
In the operation, it is apparent that the roller 9 serves as a guide for the can-opener blade due to its engagement with the side walls of a can. It is also apparent that the slot ID, formed in one of the side walls opposite the blade, serves as a clearance medium or throat, whereby said blade may be readily inserted into the top of a can for cutting out the same.
A can opener comprising a hollow handle including a top wall and side flanges, a can opening blade on the forward end of one of said flanges extending at right angles thereto, said last mentioned side flange being slotted to form a clearance throat between the blade and top wall, a rod extending through the side flanges and projecting beyond one side face of the handle, and a rotatable guide roller mounted upon the extended end of the rod adapted to engage the side wall of a can when the blade engages the top wall of the can to facilitate the travel of the opener around a can.
