Patented Dec. 16, 1952 CAN PUNCH Edwin Albert Briner, Seattle, Wash. 7 Application April 7, 1950, Serial No. 154,588 c 32 Claims.

1 This invention relates to new and useful improvements and structural refinements in can punches, and the principalebject of the invention is to facilitate convenient, safe and expeditious puncturing of cans preparatory to pouring out their contents.

An important feature of the invention resides in the provision of a can punch which may. be quickly and easily adjusted so as to accommodate cans of difierent diameters as well as of difierent types.

Some of the advantages of the invention reside in its simplicity of construction, in its convenient operation as aforesaid, and in its adaptability to economical manufacture.

With the above more important objects and features in view and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially in the arrangement and construction of parts as illustrated in the accompanying drawings, in

which:

Figure l is a side elevational view of the invention;

Figure 2 is a top plan view thereof;

Figure 3 is a fragmentary sectional view, taken substantially in the plane of the line 3-3 in Figure 1;

Figure 4 is a sectional view, taken substantially in the plane of the line 44 in Figure 2;

Figure 5 is a fragmentary sectional view, taken substantially in the plane of the line 5--5 in Figure 2;

Figure 6 is a fragmentary sectional view, similar to that shown in Figure 5 but on an enlarged scale;

Figure 7 is a perspective view of a carrier used in the invention; and

Figure 8 is a sectional view, taken substantially in the plane of the line 8-8 in Figure 1.

Like'characters of reference are employed to designate; like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in dt'aiL-the invention consists of a can punch" which zis designated generally by the reference character l0 and embodies in its construction an upright standard l2, preferably in the form of a channel having a U-shaped cross-section, the lower end of this standard being provided with a horizontally elongated base [4 which may also be in the form of a U-shaped channel having its side flanges extending upwardly, while its web portion rests on a suitable supporting surface, as is best shown in Figure 8.

in box-shaped carrier is is slidable vertically- ;on the-standard :12 and is provided with a pair .of transversely spaced, apertured ears [8 toreceive a horizontal pivot pin 20 on which-is mounted one (end portion of :a lever '22. for swing :ing "movement in a vertical plane.

The lever 22 may also assume the form of a U-shaped channel and the inner, pivotally mounted end portion thereof is provided with a longitudinally projecting tongue 24 which is receivable selectively in a vertical row of apertures 26 provided in the standard l2. In other words, when the lever 22 is swung downwardly to a substantially horizontal position, the tongue 25 extends into one of the apertures 26 and, by thus preventing the carrier 16 from sliding on the standard l2, the lever 22 is sustained in a predetermined position or at a predetermined height above the base 14. However, by simply swinging the lever 22 upwardly to the position shown in Figure 5 by the dotted lines 28, the tongue 24 is disengaged from the apertures 26 so as to facilitate sliding of the carrier I6 on the standard l2 and, at the same time, permit the height of the lever 22 above the base I4 to be adjusted.

A channel-shaped sleeve 30 is slidable longitudinally on the lever 22 and is provided with a tubular handle 32, the inner end portion of the sleeve 30 being provided with a downwardly projecting can-piercing element 34 while a similar element 36 projects downwardly from the pivoted inner end portion of the lever 22.

The base I4 is adapted to support a can 38 which is to be punched, and if desired, an upwardly projecting detent 40 may be provided on the outer end portion of the base for properly lo-v cating the can, while the inner end portion of the upstanding flanges of the base may be formed with transversely aligned notches 42 for locating cans which have a downwardly projecting bead or rim at the lower end thereof.

In any event, when the invention is placed in use, a can 38 is positioned on the base l4 against the standard l2 and the carrier I 6 is slid on the standard so that it is disposed somewhat above the upper end of the can, as shown sliding the handle 32 together with the associated sleeve 30 on the lever 22 the spacing of the piercing element 34 from the piercing element 36 may be increased or decreased so as to accommodate cans of difierent diameters, while the adjustment facilitated by the slidability of the carrier 16 on the standard l2 will enable the invention to accommodate cans of different heights.

It is believed that the advantages and use of the invention will be clearly understood from the foregoing disclosure, and further description thereof at this point is deemed unnecessary.

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

1. In a can punch, the combination of a base plate, an upright standard secured to said base plate, said standard comprising a channel-shaped member having a back portion provided with a vertical row of apertures and a pair of forwardly projecting flanges, a carrier slidable on said standard and including a front wall having a pair of transversely spaced lugs, a pair of side walls slidably engaging said flanges, and a pair of spaced inturned back wall portions provided at the rear edges of said side walls and slidably engaging said back member at the opposite sides EDWIN ALBERT BRINER.
