CAN PERFOHATOR Filed May 28, 1950 lnvenlor Patented June 30, 1 931 UNITED STATES.

ALONZO G. TURNER, OF MOOAMHON, TDAHO CAN PERFOBATOR Application filed m 28, 1930. Serial No. 456,574.

This invention relates to new and useful improvements in can perforators generally and more particularly to a device of this character which is especially adapted for use i; in perforating milk cans of different sizes but it is to be understood that a can perforator in accordance with this invention is to be utilized in connection with or for operation on any type and size of can for which same is found adapted and desirable.

An important feature of the invention resides in the provision of a novel construction and arrangement of parts whereby a can perforator is provided having no movable elements constituting a part thereof, which includes means adapting same for use in perforatin the'two widely used sizes of milk can an which is formed of a single piece of material.

All of the foregoing and other obJects and structural features of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings, wherein like charactors of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in side elevation of a can perforator constructed in accordance 3G with this invention mounted rigidly on a vertical supporting structure, 0

Figure 2 is a front elevation of the device detached from any supporting structure.

Referring to the drawings in detail, it

will be seen that reference numeral 1 designates an elongated, flat metallic plate provided with the countersunk spaced opening 2 for the passage of the anchoring screws 3 for mounting the plate vertically on a suitable support such as a wall 4. At its lower end the metallic plate 1 terminates in an inclined extension 5 providing a cam surface 6 the purpose of which will be presently set forth. The portion of the metallic plate 1 which is disposed above the uppermost opening 2 is offset laterally as at 7 and terminates in an outwardly and then downwardly extending perforating prong 8. A tongue 9 is struck out from the plate 1 at an intermediate portion thereof and terminates in a downturned perforating prong 10. As will be seen in Figure 1, the perforating prong 10 is disposed inwardly of the vertical flange of the perforating prong 8.

In use, the device is ri idly mounted in vertical position on a suita le support in the manner clearly illustrated in Figure 1 and when it is desired to perforate a comparatively small can, said can is disposed in the inclined position seen in Figure 1 with the upper end thereof engaged beneath the prong 10 and the lower end engaged on an intermediate portion of the cam surface 6. It will be noted that the vertical distance between the prong 10 and the upper portion of the cam surface 6 is less than the length of the can to be perforated. After the can is placed in the inclined position, the lower end thereof is forced inwardly and upwardly on the cam surface 6 provided by the extension 5 with the result that the prong 10 is caused to penetrate the upper end of said can when same is forced to the vertical position also indicated in broken lines in Figure 1.

Substantially the same procedure is followed when a comparatively large can is to be perforated, said large can being engaged beneath the upper prong 8. I

It is believed that the many advantages of a can perforator constructed in accordance with this invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that the changes in the details of construction may be had which will fall within the scope of the invention as claimed.

What I claim as new is:

1. A can perforator of the character described comprising a plate adapted for mounting on a support, an inclined extension on the lower end portion of the plate providing a cam surface, a perforating prong mounted on an upper portion of the plate in spaced opposed relation to the cam surface, said prong engageable with the upper end ofthe can and the cam surface engageable with the lower end of said can in a manner to force the can upwardly to cause the prong to penetrate same when the lower end of the can is forced inwardl on the cam surface, the distance between t e perforatinglprongs and the cam surface being less than t e length of the can to be perforated.

2. A can perforator of the character described comprising a plate, an extension projecting from the plate at an angle with re- 4 spect thereto and providin a cam surface, a

perforating prong forme on an intermediate portlon of the plate and disposed in spaced opposed relation to the cam surface, and a perforating prong on one end portion of the plate in spaced relation to the first named prong and in opposed relation to the cam surface.

3. A can perforator of the character described comprising a plate, an extension projecting from. one end portion of the plate at an angle with respect thereto and providing a cam surface, a perforating prong on the opposite end portion of the plate in opposed relation to the cam surface, and a perforating prong on an intermediate portion of the plate in opposed relation to the cam surface.

4. A can perforator of the character described comprising a plate, an extension projecting from one end portion of the plate at an angle with respect thereto and providing a cam surface, a perforatin prong on the opposite end portion of the p ate in op osed relation to the cam surface, and a per orating prong on an intermediate portion of the plate in opposed relation to the cam surface,

the second named prong disposed inwardly of the vertical plane of the first named prong,

5. A can perforator of the character described comprising a plate adapted for mounting on a support, an integral extension projecting from one end portion of the plate at an angle with respect thereto in a manner to provide a cam surface, an integral prong on the opposite end portion of the plate in opposed relation to the cam surface and laterally of said offset with respect to said plate, an integral prong struck out from an intermediate portion of the plate and disposed inwardly of the vertical plane of the prong and in opposed relation to the cam surface, the first and second named frongs adapted for engagement with cans 0 different sizes in a manner to penetrate same, the distance between said prongs and the cam surface being less than the length of the cans which are engaged with the prongs.

6. A can perforator of the character described comprising an elon ated metallic plate having openings therein or the passage of securing elements for anchoring said plate rigidly on a support, an integral extension wardly directe perforating prong disposed in spaced opposed relation to the cam surface, a perforating pron struck out from an 7. A can perforator'of the character described comprising an elongated, flat metallic plate having longitudinally spaced openings therein for the passage of securing elements for rigidly mounting said plate in vertical osition on a support, said plate terminating at its lower end, in an integral outwardly disposed extension providing a cam surface, the portion of the plate above the uppermost opening therein extending laterally at an obtuse angle away from the supporting structure, an integral downturned perforating prong on the upper end of the plate disposed in opposed relation to the cam surface, and an integral perforating tongue struck out from an intermediate portion of the plate between the openings therein and disposed inwardly of the vertical plane of the first named prong and in opposed relation to the cam surface.

In testimony whereof I afiix my signature.

ALONZO G. TURNER.
