onusornnnn GUIDE.

Application filed ll'anuary 2a, 1924. Serial no, 689,177;

To all whom it may concern J Beit known that-I, S MunL M. Tnnrnn, a citizen of the United States, residing at- Saint Louis, in the county of Saint Louis and State of ,Missouri, have invented oer tainnew and useful Improvements ina -Gan- QpenerGuide, ofwhich the following is a specification, I a

I This inventionappertains todevices for opening cans. and .thl p m y bje t f. h invention is to provideja novel can..opener which is so constructed th t es me w cut:..the= topv of the .canentirely of! of? the same and permitthe can to be; used over again with the addition of a lidfonhome canning'purposes; I

A fiirther object of? the: i n o is, the provision of an improved can opener having a novel cutting blade, which is so shaped, as to turn down a flange on the remaining portion of the top of the can during the opening of the can, whereby the said flange will act as a retainer for the new can top, when the same is associated with the can.

A further object of the invention is the provision of a novel guide and holder for the can opener, whereby the can opener will be held in correct position relative to the can during the opening operation, so that a complete disk of circular shape will be cut from the can top.

still further object of the invention is to provide an improved can opener of the above character, which will be durable and eificient in use, one that will be simple and easy to manufacture and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction,

arrangement and formation of parts, as will p be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a side elevation of the improved can opener showing the same in use, the canbeing partly broken away, the novel guide for the can opener being shown in diametric section.

Figure 2 is a top plan view of the can opener and the guide, and

Figure 3 is a bottom plan view of the guide for the can opener.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates the can opener therefor and C a canon which the openet and guide can be used, v y I The opener A comprises a; flat, shan'lgjf5' having one end anchored in, a suitable m ap a ng ha d g p 16- The'oute iendint I j the shank 5 has riveted or otherwise. secured to its. lower surface as at .7 a metal stripfi, 'l h forwa rl nclof th tal trip 8,5 ,113.19,- vlded with. a depending pivot 9 :andl i fOr wardly extending punching jpointdllk shown the a punching point 10'. j located, 7 at right angles to the depending pivqt 1 11151 in para le felationto the shank .51] ppm site end ofthe strip 8v is. provided a dc pending cutting l vital part of the presentginvention,

negligent posite side edges of the cutting blade 11 are beveled from the outer face toward the inner face to provide opposite'cutting edges and the lower end of the blade is beveled downwardly from the outer face of the blade toward the inner face of the blade to provide a cutting and punching point 12. The cutting edges of the blade and the Thanhpunching and cutting point 12 are so formed as to make a clean cut of the circular disk cut from the can top as will be hereinafter more fully described and to form a depending flange on the portion of the top after the disk has been cut therefrom.

The improved guide B also forms a vital part of the invention and comprises a circular top 15 and a depending flange 16 which is adapted to snugly receive the upper end of a can and to engage the side walls thereof. The axial center of the top wall 15 is provided with a pivot opening 17 for the reception of the pivot 9, for a purose, which will also be hereinafter more fully described. The top 15.at a point adjacent to the flange 16 is provided with a slot or opening 18 through which the cutting blade 11 is adapted to project for permitting the blade to cut the can top.

This guide B is so formed, that it will be necessary for the shank 5 to be always held in a horizontal position thereby insuring of the correct and easy cutting of the can top. I

which the can opener is held in a vertical position and the penetrating point 10 is inserted through the opening 17 and forced through the can. Now this insures the punching of the can at the center thereof. After the point 10 has been driven through the can top 21 the can opener is moved down to a horizontal position and the cutting blade 11 is forced throughthe slot 18 into the can. The can is now tightly held in one hand and the can opener in the other and the can opener is given a rotary movement around the can, which will effectively sever a disk from the top thereof. As the disk is being severed a flange 22 will be formed on the remaining portion of the top, which will serve as means for holding a snap lid in position on the can. It is desirable to cut the top from the can in such a manner that the can can be used over again for home canning purposes and when the top is severed in themanner described, ordinary snaps for the top such as are employed on syrup cans can be bought and associated with the can. If desired the top can be sealed by the use of suitable wax or the like.

Changes in details may be made without departing from the spirit or the scope of this invention.

What I claim as new is:

1. A can opener comprising a shank, a handle at one end of the shank, a penetrating point and pivot at one end of the shank, and a cuttingand penetrating blade carried by the shank and disposed at a point intermediate its ends, and a guide for engaging the top of the can for detachably receiving the penetrating point and pivot and the cutting blade.

2. A can opener comprising a shank, a penetrating point and pivot at the forward end of the shank, a cutting blade carried by the shank at a point intermediate its ends, a guide including acircular top and a depending flange for receiving the top of'the can, the top wall having an axial opening therein for detachably receiving the penetrating point and pivot, and a slot adjacent to the flange for detachably' receiving the cutting blade.

In testimony whereof I aflix my signature.
