Application November 16, 1950, Serial No. 196,019

1 Claim.

The present invention relates to new and useful improvements in can punches to provide a pouring opening therein.

An important object of the invention is to provide a can punch which may be moved to any desired punchin position on a can for punching one or more openings therein.

Another object is to provide a novel supporting base and guide means for a can perforating plunger and wherein the guide means forms a shield for the piercing point of the plunger.

A further object is to provide a device of this character of simple and practical construction, which is efficient and reliable in operation, strong and durable, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference bein had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view;

Figure 2 is a vertical sectional view taken on a line 2-2 of Figure 1;

Figure 3 is an enlarged sectional view taken on a line 3-3 of Figure 2;

Figure 4 is an enlarged longitudinal sectional view of the piercing point of the plunger; and

Figure 5 is an enlarged fragmentary perspective view of a modified plunger construction.

Referring now to the drawing in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of my invention, the numeral 4 designates a base of semi-circular or half-ring construction having an opening 5 at its central portion and from the rear edge of the base a strap metal guide 6 rises, and which includes a lower upstanding le I and upper and lower horizontal arms 8 and 9 connected by a vertical web positioned forwardly of leg 1.

Arms 8 and 9 are formed with guide openings ll slidably receiving a plunger l2 having a flat head l3 secured at its upper end. A coil spring 14 is placed on the plunger between upper arm 8 and head l3 to hold the plunger upwardly and stop lugs l are formed on the sides of the plunger under upper arm 8 to limit raising movement of the plunger.

The plunger is solid with a hollow lower end I6 which is beveled on a curve, as shown at H, to form a piercing point [8.

Figure 5 illustrates a plunger [9 having a hollow head 20 at its lower end which is also beveled to form a piercing point 2|, the head striking lower arm 9 of the guide to form a stop for the upward or retracting movement of the plunger.

In the operation of the device, the base 4 is placed in a desired position, on a can 22 and plunger I2 depressed to force piercing point I8 downwardly through opening 5 of the base into the can to punch the can.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

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

A can punch comprising a fiat half-ring base adapted for resting on top of a can adjacent the edge of the can, said base having end portions positioned substantially at diametrically opposite side edges of the can top and adapted to be held on the can by the hand of a person placed transversely on top of the end portions of the base and on the can, a strap metal guide rising from the base at a point substantially midway between the ends of the base and including a leg, upper and lower horizontal arms supported by the leg and a vertical web rigidly connecting the arms to each other, said base having a pilot opening under the lowermost horizontal arm and said arms having openings aligned with the pilot opening of the base, a can piercing plunger slidable in said openings, and spring means holding the plunger in a raised position with its lower end shielded under the lower arm.
