COMBINED CAN OPENER AND STOPPER.

Application filed October 19 1921. Serial No. 508,796.

' T 0 all whom it may concern:

Be it known that I, ALFREDO. ANDERSON, .a citizen of the United States, residing at in the county of Salt Lake Salt Lake City, and State of Utah, have invented certain new and useful Improvements in Combined Can-Openers and Stoppers, of which the following is a specification.

The present invention relates to a combined can opener and stopper for cans con-- taining liquid substances such as condensed milk, sirup, fruit juices, paints and varnishes, and the like. a

The object of the invention is to providean implement of this character which first punches a couple of holes in the top'for emptyin the can, and then also serves as a closure or these openings in case the can should not be drained at one time. For this purpose the implement is secured to the can and remains in this position until the can has been emptied, when it may be removed and applied to another can.

In the accompanying drawing one em-' bodiment of my invention is illustrated, and Figure 1 shows in perspective view the can opener and stopper secured to the top of a can;

Figure 2 is an elevation in partial section the implement in use; and Figure 3 is a cross section on line 3-3 of re 2. eference numeral 10 represents the can central post .of the implement. 2, Securely fastened to the upper end of the post 11 is a head 12 which is preferably knurledand the lower end of the shank is provided with a threaded point 13. A shoulder 14 is formed on the shank and against which is" tightly pressed a washer or collar 15, whichrmay be integral with the shank-and to this collar a rubber packing 16 is held. l

On the straight portion or shank of the post 11 is mounted a bridge piece 17 adapted to seat against collar 15 and revolubly and slidably connected with the post 11. This bridgepiece has two arms 18 extending in diametrically opposite directions and providedv at their extremities with a tapered point or knife edge 19. This point or knife edge is also formed with a shoulder 20.

ing 25 ml 11 the.

which tends to press the against the collar 15. The can opener is attached in the followmg manner:

The implement is placed on top of the can to be opened with its threaded (end 13 approximately in the center of the top, and after a slight blow has been delivered on the head 12 to pierce the metal on the can, the post is screwed down tightly by turning the head 12 of the post 11, until the washer 16 is compressed so as to make the opening, produced in the top of the can, air-tight. By next pressing on each end of the bridge member 17, the tapered points 19 will .pro duce a pair of longitudinal slits" or holes 25 in the top of the can. It will now be evient that the spring 22 tends to press the bridge member-downwardly and at the same bridge piece 17 pered' points or knife edges 19 and the washer 21, thereby also making these holes air-tight.

The implement might now be left in this position until the contents of the can are used, when the bridge piece 17 is first lifted and then turned about a quarter turn around the post 11, as indicated in full lines in Figure 1, leaving the openings 25 free.

- The can. may now be tilted preferably with one opening lowermost and the otheropenuppermost, and the contents will then run out of the lower opening, and the air pass into the can through the upper opening permitting free passage ofthe liquid from the can. tity of the liquid has been poured out, the bridge piece is turned back until the tapered points 19 register with the openings 25, as Indicated in dot-and-dash lines in Figure 1, and the spring 22, pressing against the bridge member 17, will close the openings tightly through the cooperation of the washers 21.

It has been found that it is immaterial what position the can has after the implement has been applied, standing upright or lying on the side, down, as the stoppers formed by the tapered points '19 and the washers 21 form a perfectly air-tight closure.

It is evident that in some instances it might be desirable to provide more than two polnts, and a modification of this kind will be covered by the scope of the invention.

With the points 19 in the shape of knife When a sufiicient quan- I or even standing-upside edges as shown in the drawing, and particularly in Figures 2 and 3, the advantage is gained that the entire top of the can may be removed after first punching the holes and then revolving the bridge member 17 a half turn. The cut out portion of the top can then be lifted by means of the can opener without falling into the can.

Having thus described the invention what is claimed as new is:

A can opener comprising a central post with ahead and a threaded end, a shoulder adjacent said threaded end and awasher under said shoulder, a two armed handle slidably and revolubly mounted on said post between said head and said washer, a, pointed double edged knife rigidly secured at each end of said arms at the same radial end.

In testimony whereo'f ll afiix my signature.
