GEORGE A. SNOW AND FRANKLIN L. OOE, OF NEW YORK, N. Y.

CAN-OPENER.

SPECIFICATION forming part of Letters Patent No. 233,813, dated October 26, 1880.

Application filed August 19, 1880.

e To all whom it may concern:

Be it known that we, GEORGE A. SNOW and FRANKLIN L. (JOE, of the city, county, and State of New York, have invented a new and useful Improvement in Gan-Openers, of which the following is a specification.

Figure 1 is a sectional elevation of the improvemen t. Fig. 2 is an edge view of the fast-- ening-band. Fig. 3 is a cross-section of the band.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish improved can-openers so constructed that they can be readily adjusted to cut larger or smaller openings as required.

A represents the stock or knife-holder, which is made in circular form,and has a handle, B, formed upon or attached to it. Upon the face of the stock A are formed one or more circular shoulders, O, which are inclined or flared, as shown in Fig. i.

D is the knife, which is made of a strip of sheet-steel of such a length as to meet, or nearly meet, when placed around the outer shoulder, O, ofthe stock A. The end edges and one side edge of the knife D are straight, and the other side edge is inclined, giving to the said inclined edge aspiral shape when the knife is bent into tubular form, as indicated by the dotted line in Fig. 1. The inclined edge of the knife I) is beveled to cause it to pass through the shell of the can more easily. To the inner side of the outer part of the wider end of the knife D is secured, by rivets or other suitable means, a strip of steel,E, the outer end of which is inclined to coincide with the inclination of the cutting-edge of the knife D. The strip E stiffens and strengthens the point of the knife D, so that it can be used for opening cans made of thicker sheet metal than would be practicable were the knife made without the said stiflening-plate. The straight side edge of the knife D is bent inward to fit upon the (No model),

beveled or flaring shoulders of the stock A, where it is secured in place byaband, F, slipped down over the knife D. The band F 18 made with a hook, G, at one end, to hook into a hole or eye. H, formed in the other end of the said band F, as shown in Figs. 2 and 3. As many holes or eyes H are formed in the band F to receive the hook G as there are shoulders O formed upon the stock A, so that the band F can be adjusted to correspond with the adjustment of the knife D.

With this construction the knife D can be detached from the stock A by sliding the band F off the said knife, and can then be adjusted upon any desired shoulder O and secured upon the said shoulder by adjusting the size of the band F correspondingly and slipping it upon the said knife D. With this construction it will be impossible for the knife D to be drawn oil the sh oulderO of the stock A when the band F is in place.

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

l. A can-opener consisting of a stock with flaring shoulders, a blade wide at one end, narrow at the other, bent into tubular form, and having straight side edge bent inwardly, a steel plate, and an adjustable band, substantially as shown and described.

2. The stock of a can-opener with one or more flaring shoulders, in combination with a blade adjustable on said flaring shoulders, substanti ally as and for the purpose set forth.

,3. The blade of a can-opener, consisting of a steel strip tapered on one edge, bent into tubular form, and having its straight side edge inclined inwardly, substantially as shown and described.
