CHARLES E. LEOPOLD, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE AMERICAN MANUFACTURING COMPANY, OF SAME PLACE.

CAN-OPENER.

SPECEFICATION forming part of Letters Patent No. 333,764, dated January 5, 1886.

Application filed October 24, 1885. Serial No. 180,794.

To all whom it may concern:

Be it known that I, CHARLES E. LEOPOLD, a citizen of the United States, residing in the city and county of Philadelphia,State of Pennsylvania, have invented a new and useful Improvement in Can-Openers, which improvement is fully set forth in the following specification and accompanying drawings,in which- Figure 1 represents a side elevation of a can opener embodying my invention. Fig.2 represents a side elevation at a right angle to Fig. 1. Fig. 3 represents a front end View thereof.

Similar letters of reference indicate. corresponding parts in the several figures.

My invention consists of a can-opener which operates effectively, is properly guided in its motions, and constructed strong, durable,and inexpensive, as will be hereinafter fully set forth.

Referring to the drawings, A represents the handle of the can-opener, and B represents the stock thereof, cast with said handle. Connected with the stock is the knife or cutter O,

the same consisting of a pointed blade sharpened on its upper edge, and having its body curved laterally in the direction of its length, said edge also being curved. Projecting forwardly and downwardly from the front of the stock is a bearingpieoe, D, and below the same is a guide, E, said piece and guide being cast with the stock, the bearingpiece being above the cutting-edge of the blade, and the guide at what may be the outer side of the blade. The bearing-piece is of arched form, whereby it is strong and durable, and the guide is continuous of the outer side of said pieoe,at the lower end thereof. The stock has a groove into which is fitted the upper end of the shank of the blade, said shank being se- (No model.)

cured to the stock by a rivet, whereby it is firmly held in position.

The operation is as follows: The point of the blade is forced into the can to be opened, piercing the same at the required place, and the piece D then resting on the outer edge or rim of the can, it being noticed that the guide E occupies a position outside of the body of the can and projects below the top thereof. The implement is now worked, and as it rises its blade cuts the can with a draw out, thus easily severing the same. In the motions of the implement the piece D bears on the can as a fulcrum, and the guide E overcomes the tendency of the blade to move to the center or leave its proper path, so that the cutting is uniform, and may be made close to the outer edge of the can. The shape of the blade also admits of the cutting being accomplished in a curved line,avoiding the angular edge left on 5 the can where a straight blade has been employed.

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

A can-opener consisting of the handle A, stock B, bearingpiece D, guide E, and curved knife 0, said handle,stock, piece, and guide being formed integral,of cast metal,the knife having its point projecting beyond and in front of the guide and bearing-piece, the latter being above the cutting-edge of the blade, and the guide at the outer end thereof, said bearingpiece being of arch form, substantially as and for the purpose set forth.

CHARLES F. LEOPOLD.
