Description
Patented Feb. 3, 1953 UNITED STATES PATENT OFFICE CAN PERFORATOR John McDevitt, Margate, N. J.
Application May 28, 1951, Serial No. 228534 1 Claim.
My invention is primarily a household tool having no moving parts.
This tool is intended for perforating tops of sifter cans, such as cleansing powder and the like. Said cans Which are made with partly cut out holes for punch out or knock out purposes.
My invention can be made of metal, plastic, or a combination of any suitable material having the proper quality of rigidity and wear resistance.
Fig. 1 is a perspective top view of my opener.
Fig. 2 is a bottom view.
Fig. 3 is a view of diso Which carries the pegs or spikes.
In the drawing- This tool consists of (Fig. 1) a cap, Or cover (A) convex or rounded on top, having a lip (D) which fits closely down over edge of can to be perforated, approximately three quarter inch.
In Fig. 2 is shown the inside View or under side of the tool which comes in contact With top of can to be perforated.
A series of pegs, or spikes, B and C, protrude downward. These pegs or spikes are arranged exactly so as to correspond or fit into punch-out holes in top of said can.
All said pegs Or spikes are approximately one half inch long, except one (B) which is known as the pilot peg." Said peg to be one inch in length, so as to be one quarter inch longer than lip of can.
The purpose of this pilot peg" is explained in the following, Method of operation" or "Directions.
First-Place the tool so that the pilot peg (B) is directly over one of the punch-out holes in top of can.
Second-Press down On tool until this one hole is perforated.
Third-Move tool around so as to fit perfectly over top of can, and press down until all holes are perforated. The pilot peg must be kept in hole which it perforated while tool is being moved into position.
The pegs or spikes are built into the underside of perforator on a fiat disc (Fig. 3). Said diso fits closely under top surface of tool, and
2 pegs (B) and (C) are welded, soldered, or cemented to diso in proper position.
The disc is then set in any suitable material so as to hold it firmly in place on inside of tool; a thin layer of said material to cover disc and around pegs.
In my invention, the pilot peg having punctured the first punch-out hole (a visible operation) guarantees that all the other pegs will meet the other holes (an invisible operation), owing to the fact that the tool has completely covered top of Can, but all pegs (B) and (C) are set in position to automatically meet punch-out holes.
In the drawing a total of eight pegs (B) and (C) is shown. But difierent makes of cans, having greater or lesser number of punch-out holes, require a separate tool. As the pegs are not adjustable, separate tools are made with the proper number of pegs to correspond with punchout holes, but having all the other features of my invention.
I claim:
An opener for sifter top cans comprising a cap having a flat top diso and a dependent fiange on the edge of the disc to fit over top of the can to be opened and a plurality of punching elements carried by a second diso secured to the top, one of said elements being longer than the depth of said fiange and the remaining elements being shorter than the depth of the fiange, Whereby the long element locates the opener on the Can prior to the action of the remaining elements.
JOHN MCDEVITT.
