CAN OPENER Filed May 24, 1955 Patented Dec. 24, 1935 UNITED STATES PATENT OFFICE CAN OPENER Harry Haudenschild, Maumee, Ohio Q Application May 24, 1935, Serial No. 23,298

3 Claims.

, This invention relates to can-opening devices, and is more particularly directed to a can puncturing and forming means.

The primary object of the invention is the provision of a can puncturing device, which, in the course of its puncturing operation, will form a portion of the can into a pouring spout.

Another object of the invention is the provision of a device of this character which is inexpensive to make, sturdy in construction and certain, efllcient and rapid in operation. Other objects and advantages of the invention will become apparent asthe description proceeds, reference being had to the accompanying drawing, in

which- Figure 1 is a perspective view of the device applied to a. can; Fig. 2 is a fragmentary elevational 'view of the tool itself; Fig. 3 is a side view thereof; Fig. 4 is a central vertical section, with parts in full, of the tool in operating position on a can, and

Fig. 5 is a section on line 5-5 of Fig. 4.

Referring to the drawing, the device is adapted to operate on any typeof can having a side wall I and a top 2 united therewith as a closure member. In the instance of cans containing liquids such as evaporated milk, fruit juices, lubricating oils, etc., it is desirable to open the can only by puncturing the top and at the same time provide a pouring spout.

The tool itself comprises a; handle 4 which may be formed of wood, or other suitable material, in

. any desired configuration. A sharpened punch part 6' is connected to the handle through its shank in any desired manner. This punch part is provided with opposed converging cutting edges and is curved and reduced in width at its lower end, so as to present a sharp piercing point to the can surface without decreasing the thickness of the stock of which the punch is made.

The curvature of the punch brings theinitial point of contact with the can top 2 well inside the edge of the can so that the punch forms an opening of the desired size by progressively press-- ing out a tongue like area of metal attached to the edge of the can.

A forming guiding body I having spaced guide legs 8 depending therefrom is fixed to a side of the punch by rivets Ill, or other suitable fastening elements, so as to be substantially integral with the punch part. The guide legs 8 are curved so as to lie out of the plane of the body I for a purpose which will presently become apparent.

A can forming die part II, which is substantially V-shape in cross-section, is also formed integral ith the body I and extends downwardly therefrom between the guide legs8 and is bent to lie against and conform to the curvature of the punch part 6. While the forming part I2 is part of the body I, it is in effect a part of the punch, as it cooperates therewith to form the tongue out by the punch and the side walls into the desired shape. It will be seen, in Fig. 5, that the apex of the die part I! faces outwardly from the part 6 and extends beyond the inner plane of the guide legs 8. 10 In operation, when it is desired to open a can, the point of the punch G-is placed on the top of the can while the guide legs 8, which are longer than the punch, are placed in contact with the outer periphery of the can. The entire device is 15 then forced downwardly so that the punch l penetrates the top of the can; Continued downward movement of the tool forces the forming die l2 and tongue into engagement with the edge of the can so that this'part becomes distorted to 20 conform to the configuration of the triangular area formed by the die l2 and guide legs 0, as shown in Fig. 5. The fact that the outer surface of the v-shaped die member lies beyond the inner surface of the guide legs 8 causes the 25 opening made in the can to assumetriangular configuration which is suitable for a pouring spout. It will be seen that the tongue punched from the top of the can in forming the hole or opening therein is forced inwardly from the can 30 top and rearwardly of the punch and die member, so as to lie closly adjacent the side wall of the can.

While the invention has been described in connection with a particular construction, it should 35 be appreciated that it may be made in various ways and may assume various forms. It should be expressly understood that the inventionis not limited to the form shown, but may properly include all such modifications as may fall within 40 the scope of the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent, is:

1. In a device of the class described, guide 45 means adapted to lie at the outside of the side wall of a can, a punch member inwardly disposed with respect to said guide means and adapted to engage a. can top and form a tongue from such top and bend it inwardly and against the side 50 wall of the 'am when the device is forced inwardly with respect to the can, said punch having provision for cooperating with said guide means to form the tongue and adjacent side wall of the can into a pouring spout. 55

2. In a device of the class described, guide means adapted to lie at the outside of the side wall of a can, and a punch member having cutting edges terminating in a piercing point, and forming means adapted to engage the can top and progressively cut a tongue from such top, bend it inwardly and against the side wall of the can and form a pouring spout when the device is forced inwardly with respect to the can.

3. In a device of the class described, guide means adapted to lie at the outside of the side wall or a can, a punch member having opposed converging cutting edges which extend gradually outward relative to said guide means and terminate in a piercing point adapted to engage the can top and progressively cut a tongue from such top and bend it inwardly and against the side wall of the can when the device is forced inwardly with respect to the can, said punch having provision for cooperating with said guide means to form the tongue and adjacent side wall of the can into a pouring spout.
