CAN TOP PUNCHING IMPLEMENT Filed Aug. 20, 1931 the punch.

Patented July y l2, 1932 BERT GEER, OF MARYHILL, WASHINGTON CAN TOP PUNCB'ING IMPLEMENT Application led .August 20, 1931. Serial N0. 558,374.

This invention relates to implements for punching holes in. cans to permit the discharge of the contents and the general object of the invention is to provide a very simple, easily operated and convenient im.

plement of this character adapted to simultaneously punch a discharge aperture in the can and an aperture for the inlet of air and furthermore to so form the outlet aperture that it constitutes, when formed, a slightly projecting spoutso that the contents of the can may be readily poured off.

A further object in this connection is to provide a can punching device of this character in which the can is punched by a tr1angular blade or punch adjacent the side of the can and the material of the can top is forced inward and the side of the can is slightly forced outward, thus constituting the small spout before referred to.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawing, wherein Figure 1 is a side elevation of my can punching device, the can and bracket being shown in section;

Figure 2 is a. section on the line 2-2 of Figure 1;

Figure 3 is a fragmentary elevation of the bracket and punch operating lever;

Figure 4 is a fragmentary elevation of the structure shown in Figure 3, looking toward Referring to the drawing, designates an angular bracket apertured at one arm as at 11 so that screws may be passed through these apertures and hold the bracket to the wall and also preferably apertured at 12 so that screws may be passed -through the outwardly projecting arm 13 of the bracketv to hold the bracket upon a base. This arm 13 at its extremity is upwardly turned as at 14. This arm 13 has a length closely approximating the diameter of a standard size can so that when the can is in place, the base of the can will rest between the arm 10 and the upturned end 14 as upon a seat. The upwardly extending portion of the bracket 10 has a height slightly greater than the height of a standard can and the upper end of this bracket is bifurcated at 15. The arms of this bifurcated portion are bent around as at 16 to form a vbearing for a transverse pin 17. Mounted within the fork thus formed and upon the pin 17 is a lever 18, the inner end of which is bent to surround the pintle 17 and is then extended, then bent forward upon itself, as at 19 and then extended downward and rearward to constitute a curved triangular blade 20. This blade is sharp pointed at its lower end and the rear face of this blade is beveled at 21 so that the lower end of the blade is formed not only with a sharp point, but the rear face is formed with the vertical cutting edge 22.

The lever may be of any desired length, but is provided at a distance from the pivotal end of the lever with a prong or punch 23 which may be attached to the lever or' may be formed integral with the lever or made in any desired manner.

The lever may have any desired length, but the punch 23 is disposed a distance from the 75 blade or tooth 21 equal to the diameterl of a standard can.

While the bracket 10 may be disposed in any position, in other words, with the arm 13, for instance, extendingupward or extending horizontally, yet I will assume that the bracket 10 is mounted in a vertical position. with the arm 13 extending horizontally outward.

In order to punch a can, the can is placed upon aseat formed by the arm 13, the lever 18 being raised. The lever is then depressed and as it is depressed, the blade 20 is'moved downward and outward toward the rim of the can. Under these circumstances, the point of the blade will enter'the can at a slight 90 distance from the rim or side wall of the can and as the blade is depressed, a triangular spout is completed by the depression of the lever, the punch 23 will enter the opposite margin of the can and will punch a hole therein so that air may enter the can to permit the 5 pouring of the contents.

This implement is designed as a household convenience for punching milk cans, molasses cans, or other cans of like character. The spout permits the liquid to be poured as from a. 4pitcher with no dribble down the side of the can. The implement may be fastened to the wall or to a horizontal surface or merely held in the hand or set upon any surface for operation.

The lever may be varied as before stated, but preferably, it is of such length as will allow the operator to complete the punch without engaging his knuckles or any part of his hand with the can. The implement may :40 be iliade of only three parts if the air vent punch is cut out or formed in the lever handle itself.

1. An implement of the character described, comprising a bracket bent at right angles to form a can supporting seat and a portion extending at right angles to the seat, said portion at its end remote from the seat being bifurcated and having a transverse pintle, a lever pivotally mounted on the pintle to swing toward or away from the seat, the lever closely adjacent the pintle being formed with a blade extending toward the seat, the blade' being triangular and having its side edges beveled in a direction inward and away from the extremity of the lever, said blade being so positioned upon the leventhat it enters the junction between the top and sides of a can whereby as the lever is swung downward, the

40 blade will be swung downward and outward to punch a. hole in the can lid and press out the side ofthe canto form a spout.

2. -A can punching implement of the character described, comprising a right angular bracket, one arm of the bracket being provided with apertures for the passage of attaching screws, one arm of the bracket at its extremity being upwardly bent whereby said arm may form a can seat. the other arm of the bracket being bifurcated. a pintle extending across the bifurcation and a lever formed at one end to form an eye embracing the pintle and beyond said eye being bent toward said seat to form an end piercing blade, said 55 blade being triangular in form and the edges of the blade being beveled toward each other in a direction away from the extremity of the lever, the lever having a punching tooth inv spaced relation to said blade and adapted 69 as the blade enters a can to enter the can to form an air inlet opening.

3. A can punching implement of the character described', comprising a can seat having 'an outwardly extending bracket bifurcated at its outer end, a pintle extending across the bifurcation and a lever formed at one end to provide an eve embracing the pintle and constituting a ulcrum for the lever, said lever inward of said eye being bent downward and outward to form a can piercing blade, said blade being triangular in elevation andthe edges of the blade being beveled toward each other in a direction away from the extremity of the lever whereby as the lever is depressed in a position parallel with the can, the piercing bar will simultaneously pierce the can top and force the side wall of the can outward through the bifurcation of said bracket to form a spout.

4. A can punching device comprisin an upright engageable against the side o the can, said upright at its upper' end being bifurcated and having a transverse pintle, a lever pivotally mounted on the pintle to swing vertically, the bifurcated port-ion of the bracket being formed with a blade extending toward the seat, the blade being triangular in cross section and having its side edges beveled in a direction inward and away from the extremity of the lever whereby as the lever is swung downward, the blade will enter the top of the can closely adjacent the side wall thereof and force this side wall outward into the bifurcation of the vertical portion of the bracket to thus form a pouring lip on the can.

In testimony whereof I hereunto a`n`x my si gnature.

BERT GEER.
