COMBINED CAN PERFORATOR AND CLOSURE.

Specification of Letters Patent.

Patented July 24, 191?.

' Application filed July 24, 1916. Serial No. 113,027.

To all whom it may concern:

Be it known that I, MICHAEL WILD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Combined Can Perforators and Closures, of which the following is a specification.

My invention relates to combined perforating and closure means for milk cans and the like and the primary object is to provide a simple and eflicient device of sanitary character which may be used principally for piercing the tops of condensed milk cans so that the milk may be poured from the cans readily when the can is tilted, but which, when the can is held or supported vertically, will completely close the perforations thus made and prevent the entrance of dirt into the cans. Flies are also prevented from having access to the openings in the can, and this feature alone commends my device to householders.

It is usually necessary to provide but a very small opening in the tops of the can as relatively small quantities of the milk are used at a time, and in order that the milk may flow readily from the opening I provide another opening in the can top through which the air may enter the can. Other objects may appear as the description of my invention progresses.

Referring to the drawings, Figure 1 is a plan view of my device attached to the top of a can; Fig. 2 is an elevation of the same, in section on the longitudinal center line of Fig. 1; Fig. 3 is a front end elevation; and Fig. 4 is a rear end elevation. Similar characters of reference are used 'in the vanous views of the drawing and in the specification to indicate like parts.

My device comprises two members, the lower member 1 forming a base and being capable of attachment to the top of thecan 2 and the other member 3 bemg pivoted thereto. The member 1 is bifurcated at the front end and the furcations 4 are bent upwardly and then downwardly to form resilient clamps and are adapted to be forced downwardly over the bead 5 of the can 6.

e rear end of the member 1 has a single centrally formed clamp 7 which resiliently engages the opposite side of the head 5 and on each Side of the clamp 7 a hinge extension 8 is formed which is extended upwardly above the central body of the member 1. An operating lever, which constitutes the member 3, hereinbefore referred to, is pivotally attached to the member 1 at the rear end by means of the hinge pin 9 which extends through the extensions 8 on the member 1 and the similar extensions 10 on the lever. An extension lip 11 is formed on the lever 3 at the rear and is extended sufficiently back of the hinge joint for raising the lever from its normal position, this extension being bent upwardly over the hinge.

The front portion of the lever 1 extends over the top of the can and the body of the member 3 and is provided with two cutters 12 and 13 which are flat and relatively narrow and are reduced at their upper ends and riveted to the body of the lever. ters may be suitably arranged as shown in Fig. 2, or otherwise, as convenience may require.

The forward cutter 12, which is the longest of the two, is preferably positioned at a point near the periphery of the can 6 and the other cutter 13 may be positioned at a point on the opposite side of the center, preferably near the opposite portion of the periphery of the can. The cutter 13 is substantially shorter than the cutter 12 so that when the device is placed in position on the can top the points on both of the cutters may both rest thereon before the perforating operation, so that but a single pressure on the part of the operator will be required to make both perforations. The cutter 12 engages the can top 14 between the furcations 4 of the member 1, and the cutter 13 engages the top through the opening 15 formed in the sure of the hand of the operator on the flat surface of the lever 3 which rests normally above the member 1 operation, causes the points of the cutters 12 and 13 to pierce the can top 14 and the openings l6 and 17 are made in the top of the can. It is preferable, for the best results that the lever 3 should be forced downwardly until it will rest upon the body of the member 1, so that no dirt can enter the openings and flies will be prevented from having access to the portion of the can top on which any of the milk may remain after the openings are made. It is apparent that when the can is in an upright position, as shown in Fig. 2, the lever 3 will rest upon These cut- 7 prior to the perforating member 1, and a slight presthe member 1 and the cutters 12 and 13 will occupy the openings in the top of the can which conform exactly to the shape of the cutters by which they were formed, thus providing closures for the openings.

When the can is inclined for pouring off a quantity of the milk therefrom, the lever 3 may be raised by pressing downwardly on the extension lip 11, when the lever will occupy a position as indicated by the broken lines in Fig. 2, or, the lever may be permitted to fall by gravity, which it will do readily if the finger of the operator does not prevent.

It is obvious that the cutters may be made of any desirable shape or size to suit the requirements and many other modifications may also be made in the device without enlarging the scope or departing from the spirit of my invention.

Having thus described my invention, what I claim is:

1. A combined can perforator and closure therefor including a base member removably and resiliently attachable to the can in proximity to the top thereof, and cutter means arranged to operate through said base member for perforating the can at one or more points, said cutters forming closures for the perforations in the can when the can is'supported in upright position.

2. A can perforator and closure comprising a base resiliently and removably supported on the can in proximity to the top thereof, and an operating member pivotally supported on one end of said base and provided with cutters for perforating the can top at points and capable of movement in a plane longitudinally of the can to permit the emission of the contents therefrom and the admission of the air thereto, said cutters forming closures for the perforations when the can is supported in an upright position.

3. A can perforator and closure comprising a base resiliently and removably supported on the can in proximity to the top thereof, and an operating member pivotally supported on said base and provided with a pair of cutters operable through said base for perforating the can top at difierent points, said cutters forming closures for the perforations thus made when the can is in an upright position and being movable out of the perforations when the can is inclined for discharging the contents of the can.

4:. A can perforator and closure comprising a base member resiliently and removably held in position on the can top, and an operating member hinged thereto and capable of movement Vertically relative thereto, cutters being provided on said operating member for piercing the can top and said cutters being operable through said base member.

5. Acan perforator comprising a removable base and an operating member pivoted thereto having a pair of cutters movably held for piercing the can top, openings being provided in said base to permit the ac tion of the cutters on the top and said outters being capable of use for closing the openings thus made.

Signed at Los Angeles, in the county of Los Angeles and State of California, this 5th day of July, 1916.
