FABIUS R. PENDLETON, OF BOSTON, MASSACHUSETTS.

CAN-OPENER.

SPECIFICATION forming part of Letters Patent No. 766,379, dated August 2, 1904.

Application filed November 30, 1903. Serial Be it known that I, FABIUS RAY PENDLE'ION, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Can-Openers, of which the following is a specification.

This invention relates to improvements in can-openers; and the main object of the invention is the provision of a can-opener which provided with means for protruding the center of the top of a can, said means being slidably mounted within a handle which carries a stationary cutting-blade and a retaining cutting-blade in combination with a revoluble guard.

Another object of my invention is the provision of a simple, durable, and inexpensive construction of can-opener which is thoroughly efficient and practical in use.

To attain the desired object, the invention consists of a can-opener with novel features of construction and combination of parts, substantially as disclosed herein.

In the accompanying drawings, Figure l is a side elevation of the complete can-opener. Fig. 2 is a longitudinal sectional view through the handle and the guard and cutting devices with the sliding rod in elevation. Fig. 3 is an end view of the can-opener looking from the sliding rod toward the guard-disk.

Referring to the drawings, the letter A designates the handle, which is provided with the longitudinal socket B, extending from its inner end toward the handle portion. Fitting in the end of the socket is a sleeve C, in which is slidably mounted the adjustable rod D, having upon its inner end a projecting collar F, which prevents the complete withdrawal of the rod, said rod being adapted to slide within the socket of the handle. Upon the outer end of this rod is provided the abutting collar or shoulder F and the slightly-hooked point G, which is adapted to be forced into the central portion of the top of a can. Carried upon the outer end of the sleeve is a disk H, to whose rear face is secured the stationary double edged cutter J, and revolubly mounted upon this collar opposed to the rear of the stationary cutter is a disk cutter K.

-cutting thereof.

(N0 model.)

Mounted upon the sleeve and adapted to properly space the disk cutter and the rotatablymounted circular guard L is a loosely-mounted washer or collar M.

From the foregoing description, taken in connection with the drawings, it is evident that 1 provide a very simple and durable opener the operation of which is as follows: The hooked point (i of the rod is first forced into the center of the top of the can, and then the handle of the can-opener is pushed downward and slid in toward the center, so as to bring the cutting-blades at the desired point with relation to the center of the can. At this time the guard should be in contact with the rim and the vertical walls of the can, so as to present the rotary cutter K at the desired point upon the top of the can for the The rotary cutter is then operated by moving the handle, using the end of the rod as a center, until the out upon the top of the can is started, at which time the stationary cutter J is placed in the cut made by the rotary cutter, so as to cut the top from the can.

By employing the adjustable rod and guard should the point of the rod strike out of the center of the top of the can the rod will slide freely, as the guard will follow the contour of the walls or top of the can, thereby adjusting the cutters so that they should cut the top of the can at an even distance from the edge.

By employing the rotary cutter to start the cut the stationary cutter is saved very much wear and the amount of pressure required to start the cut is very much lessened, and it has therefore been my object to produce a canopener which is provided with a self-adjustingrrod, a rotary cutter to start the out, a stationary cutter to complete the cut, and a guard which will absolutely adjust the cutters so that they will cut an even distance from the top of the can.

By means of the shape of the shanks point should the point strike out of the center of the can the shank will freely slide to adjust the cutters so as to cut the can an even distance from the edge. I also use the can-opener in the following mannerthat is, I start to cut with the rotating disk and then turn the a guard carried by the handle adapted toguide the cutters in their movement with relation to the end of the rod.

2. In a can-opener, the combination of a socketed handle, a rod mounted therein and carrying a working point in the opposite end, a rotary and stationary cutter carried by the handle, and a revolubly-mounted guard carried by the handle exteriorly of the'cutters.

3. In a can-opener, the combination of a socketed handle, a rod slidably mounted in the handle and providedwith a working end to project through the top of the can, a sleeve mounted in said socket of the handle, surrounding the rod and projecting beyond one end of the handle, a stationary cutter carried upon the extreme end of said sleeve, a rotary cutter surrounding said sleeve, and a rotary guard surrounding said sleeve between the rotary cutter and handle.

4. In a can opener, the combination of a handle provided with a socket therein, a sleeve fitting in said socket and projecting beyond one end of the handle, a rod slidably mounted within said sleeve carrying a working end to engage the top of the can, a stationary cutter, a rotary cutter and a guard carried upon the projecting end of said sleeve for the purpose set forth.

engage the top of the can, a disk carried upon the outer end of said sleeve, a stationary cutter secured to the rear face of said disk, a rotary cutter revolubly mounted upon said sleeve, and a rotary guard loosely mounted upon the sleeve between the rotary cutter and handle.

6. In a can-opener, the combination of a handle provided with a socket, an adjustable rod provided with a working point slidably mounted in said socket, a sleeve mounted in the socket surrounding said rod and having one end projecting beyond the handle, means for cutting the top of the can carried by said projecting end, and a guard mounted on the sleeve interposed between the end of the handle and the cutting means.

7 In a can-opener, the combination of a handle provided with a socket, a sleeve mounted in said socket and projecting beyond the end of the handle, a rod provided with a working point slidably mounted within said socket, means carried upon the end of the rod mounted in the socket to prevent the withdrawal of the rod from the socket, means for cutting the top of the can carried by the extended end of the sleeve, and a guard interposed between the cutting means and the handle for the purpose set forth.

In testimony whereof I affiX my signature in presence of two witnesses.

FABIUS R. PENDLETON.
