CAN-OPEN ER.

SPECIFICATION forming part of Letters Patent No. 601,182, dated March 22, 1898.

Applioation filed May 11, 1897. Serial No. 636,987. (No model.) I

To a'ZZ whom may concern.- I

Be it known that I, SYLVANUS D. TALBERT, of Ouray, in the county of Ouray and State of Colorado, have invented certain new and useful Improvements in Gan-Openers; and I do hereby declare the following to be a full, clear,

and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to can-openers, the object of the samebeing to provide a simple and elfective device for opening cans which will cut a perfectly round opening in the top or bottom thereof and in which the size of the opening cut may be regulated.

The invention consists of a flat bar having a handle formed upon one end thereof and a longitudinal slot in its opposite end, a cu ttingtooth secured to one side of said bar, a plate having flanges at its opposite ends adapted to embrace said bar, and a prong extending through said slot and through a threaded opening in said plate provided with means whereby it may be turned for the purpose of clamping it at different points upon said bar.

The invention also consists in other details of construction and combinations of parts, which will be hereinafter more fully described and claimed.v

In the drawings forming part of this specification, Figure 1 represents a perspective view of my device shown applied in the position it assumes in the act of cutting the head of a can. Fig. 2 is a top plan view of the same. Fig. 3 is a detail sectional view.

Like reference-numerals indicate like parts in the diiferent views.

My improved can-opener is made up of a fiat bar 1, of any suitable metal, having a handle 2 formed upon one end thereof and a longitudinally-extending slot 3 at the opposite end. Secured to the under side of the barl, at a point adjacent to therear end of the slot 3, is a cutting-tooth 4.. Upon the under side of the bar 1, adjacent to the slot 3 therein, is a plate 5, which has upturned flanges 6 6 at opposite ends thereof, which engage the outer edges of said bar and serve as guides for preventing the lateral displacement of said plate.

This plate has a threaded opening 7 extending through it, in which opening fits a pointed prong 8,having screw-threads 9 upon it, which engage the screw-threads in said opening, and a handle 10 upon its upper end, by means of which said prong may be turned. Upon the lower end of said handle is formed a shoulder 11, which engages the upper surface of which brings the shoulder 11 into close contact with said bar and clamps the plate 5 and the prong secured thereto firmly to the bar 1.

In using my device the pointed end of the prong 8 is forced through the top or bottom of the can at its central point. The said prong and the knife 4 are so adjusted relatively that the knife 4 will engage the upper end of the can at a point adjacent to its outer edge. With both the prong 8 and the blade 4 forced through the upper end of the can it is merely necessary in order to cut a circular opening in the can for the operator to draw the handle 2 toward him. The cutting edge of the blade a will then be brought into engagement with the top of the can at an acute angle, cutting a circular opening with the prong 8 at the center thereof.

By making prong 8 with screw-threads it is not only more easily forced through the top of the can by turning the handle 10, but when so forced in the screw-threads engage with the material of the can and securely hold the prong in place.

The device is extremely simple in construction, can be cheaply made, and is effective for the purpose for which it was designed.

Having now described the invention, what I claim as new, and desire to secure by Letters Patent, is

In a can-opener, the combination with the bar formed with alongitudinal slot in one end, and with a handle at the opposite end, and

provided with a cutting-tooth intermediate In testimony whereof I have signed this its ends, of the plate having its ends turned specification in the presence of two subscribupwardiy forming flanges embracing the sides in g witnesses. of said bar and the screw-prong passing SYLVANUS D. TALBERT. through a screw-threaded opening in said Vitnesses:

plate, formed with a circular shoulder bear- 0. O. SNARE,

ing upon said bar, substantially as described. I A. U. SMITH.
