Murphy Application February 2, 1951, Serial No. 209,065

1 Claim.

The present invention which is a continuation in part of application 94,573, filed May 21, 1949, pertains to a novel punch for cutting holes in cans containing various liquids such as milk, juices, and the like.

The principal object of the invention is to provide a simple punch that can be set upon the can and operated manually. Another object is to provide a punch that can form successively triangular and round holes in the can. Still another object is to provide an integral guide for positioning the punch properly on the can. A further object is to provide a conventional bottle opener and cork screw incorporated in the body of the device.

In the accomplishment of these objects, the device comprises a body with a spring-raised punch member therein. This member has a straight, sloped cutting edge of triangular section whereby the form of the hole cut in the can may change from triangular shape to a round hole. The bottom of the body is formed with a curved lip that engages the edge of the can to locate the punch. The punch is guided in order not to rotate in the body.

The invention is fully disclosed by Way of example in the following description and in the accompanying drawings in which:

Figure l is a perspective view of the device;

Figure 2 is a longitudinal section;

Figure 3 is a detail elevation of the punching member;

Figure 4 is a part bottom plan view; and

Figure 5 is a detail longitudinal section in a different position of Figure 2.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

In Figures 1 and 2 is shown an elongated body I formed at one end with a vertical column 2. The upper end of the column is formed with a recess 3 in which is slidably mounted a head 4. A spindle 5 is secured to the head 4 and passes through the bottom of the recess 3 into a cavity 6 in the bottom of the body I. The cavity 6 is cylindrical and the body is also formed with a pair of slots or grooves 1 communicating with the cavity 6 for a purpose that will presently be described.

A coil spring 8 in the recess 3 bears on the bottom of the recess and against the top of a counterbore 9 in the head 4, thereby normally lifting the head and the spindle 5. The lower end of the spindle is shaped as a triangular blade lil having a sloping cutting edge H. The blade W at its upper part is angular at l2 for a purpose to be described. A pin 13 passed through the spindle 5 is guided in the slots 1 and lies in the same axial plane as the edge ll.

The forward lower edge of the column 2 is formed as an arcuate lip l4 extending downwardly beyond the plane of the bottom of the body I. In use the body is set upon a liquid containing can [5, and the lip 14 serves as a guide on the edge of the can. The blade I!) is pushed through the top of the can by pressure on the head 4. The size of the hole thus formed is triangular. By further pressure applied on the head, due to the slope of the edge l2 the triangular hole will become round. A small hole may be cut for milk cans and a larger round hole for cans of fruit or vegetable juice. The small hole may be used for air and the larger for emptying the can.

In the bottom of the body I is formed a longitudinalrecess It in which is pivotally mounted on a transverse pin I! a hooked end l8 of a wire which when swung out as in Figure 4, is adapted to remove the cap from a bottle I9. To the other end of the wire is formed a spiral cork screw 20.

Although a specific embodiment of the invention has been illustrated and described, it will be understood that various alternations in the details of construction may be made without departing from the scope of the invention as indicated by the appended claim.

What I claim is:

A can opener comprising a body portion having a vertically extending aperture therethrough, a first recess in said body in communication with said aperture, said recess opening into the bottom of said body, a second recess in the top of said body in communication with said aperture, a rod slidably mounted in said aperture, stop means carried by said rod extending into said first recess, said rod having a pointed end and a threaded end, a head detachably secured on said threaded end, a recess in said head, and a spring biasing said head and said body, said spring being engaged in the recess in said head and in said second recess, said spring being coaxial with said rod, said rod having an opening extending transversely therethrough, said stop means comprising a pin received in said opening.
