UNITED STATES PATENT OFFICEQ CHARLES ARON ANDERSON AND OSCAR ANDERSON, OF PORTLAND, OREGON.

CAN-OPENER.

SPECIFICATION forming part of Letters Patent No. 664,033, dated December 18, 190i) Application filed August 25, 1900.

To all whom it may concern:

Be it known that we, CHARLES ARON AN- DERSON and OSCAR ANDERSON, citizens of the United States, residing in the city of Portland, county of Multnomah, State of Oregon, have invented certain new and useful Improvements in Can-Openers, of which the following is a full, clear, and exact description, reference being had therein to the accompanying drawings, in which Figure 1 is a perspective view showing the device in operative position; Fig. 2, a plan View of the knife-carrying bar; and Fig. 3, a side elevation showing the device in operative position, the can and a portion of the knifecarrying bar being in sectional view.

The invention has for its objects to provide a device of this class which shall be simple in its construction, and therefore may be cheaply manufactured, effective in operation, and which may be readily adjusted for use on cans of different sizes.

Referring to the various parts by numerals, 1 designates the lever-bar, which is formed at one end into an entering-point 2, which is L-shaped, as shown, and is adapted to form a fulcrum for the lever-bar. The other end of this lever-bar is formed into a flat handle part 4, and a portion of the bar adjacent the entering-point is formed rectangular in crosssection, as shown at 5. Sliding on this rectangular part of the lever-bar is the cuttercarrying bar 6. This bar is formed at one of its ends with an integral forward-extending cutter or knife 7, and on each side of this cutter is formed a depending guide-lug or stop 8, which fits close against the side of the can when the device is in operation, the two lugs maintaining the cutter a certain distance from the edge of the can-cover at all times during the operation of cutting out the cancover, as shown clearly in the drawings. This cutter-carrying bar just above the cutter is provided with an opening 9, which is rectangular and through which the rectangular portion of the lever-bar extends. A short distance above the opening 9 this bar is bent slightly to bring the handle thereof near enough to the handle of the lever-bar so that both of said bars may be conveniently grasped in one hand. Above the opening 9, on the right-hand edge of the cutter-carrying bar, is

Serial No. 28,052. (No model.)

a depending lug 10, which forms a stop, said stop engaging the right-hand edge of the lever bar during the operation of opening a can and preventing any rocking or lateral motion of the cutter-carrying bar.

When using the device, the entering point of the lever-bar is forced down through the can-top, at the center thereof, and then said bar is swung down until the cutter is near the top of the can. The cutter-carrying bar is now slid along the lever-bar until the stops or guide-lugs are close to the side of the can, so that when the cutter is forced through the can-cover said stops will contact with the side of the can, as shown in Fig. 3. After the cutter has been forced through the can-top the handle ends of the two bars are grasped in one hand and sufficient pressure brought thereon to cause the two transverse edges of the opening9 in the cutter-carrying bar to bind on the lever-bar, one of said edges binding on the upper surface and one on the under surface of said bar, as shown in Fig. 3,.and thereby hold the two bars practically immovable with respect to each other. The device is now swung around on the pivot or fulcrum and the cover cut out. The lug 10 bears on the right-hand edge of the lever-bar and prevents any lateral movement of the cuttercarrying bar on the lever-bar during the cutting operation. It will be noted that the cutter is inclined downward and in the direction of the cntthat is, toward the left as shown in the drawings. This is so that the cutter will make adraw out, the cutter as it is forced around tending to lift the can-top and slide it up the cutter, and therebyinsuring a steady cutting action, which will not cause the metal of the can-top to buckle.

It willthus be seen that the device is readily adjustable to cans of various sizes and can be readily and cheaply made, as there are no separate clamping devices to be specially made and secured to either of the bars, the bars themselves forming the clamping members. It will also be noted that by reason of having the guide-legs 8 and the stop 10 the lever-bar maybe made perfectly smooth on its upper and under sides to permit the cutter-carrying bar to be readily slid back and forth thereon in adjusting the cutter to the can, these stops preventing any inward or any lateral movement of the cutter-bar during the operation of openinga can and rendering it unnecessary that these bars be clamped together as tightly as would be required if the clamping means were depended on entirely to maintain the two bars immovable with respect to each other during the cutting operation. The binding action of the two edges of the opening caused by grasping the two handles during the cutting operation will be sufficient to hold the cutter-bar against outward movement on the lever-bar.

What we claim is 1. In a can-opener, the combination of a lever-bar formed with a handle part and an entering-point adapted to form a fulcrum, a cutter-carrying bar provided with an opening through which the lever-bar works and with an outward-extendinghandle partlyingabove and adjacent the handle part of the lever-bar, so that both said handle parts may be grasped with one hand, a downward-extending cutter on the inner end of the cutter-carrying bar, a guide-lug or stop formed on the cutter-carrying bar adjacent the cutter and adapted to engage the, side of the can and prevent the cutter-bar moving toward the fulcrum-point of the lever-bar while in operation.

2. In a can-opener, the combination of a lever-bar provided with an entering-point adapted to form a fulcrum for the lever, a cutter-carrying bar adapted to slide on said leverbar and provided with a downward-extendin g cutter and a depending stop adapted to engage the side of the can, and a downward-extending lug formed on the side of said cutterbarand adapted to engage the right-hand side of the lever-bar, substantially as described and for the purpose set forth.

3. In a can-opener, the combination of a lever-bar provided at one end with an entering fulcrum-point and at its other end with a handle, a cutter-carrying bar bent downward at one end and provided with a pair of stoplugs and a euttertherebetween and atits other end with a handle lying above. and adjacent to the handle of the lever-bar, this cutter-carrying bar being provided with an opening in the downward-bent portion, just above the cutter, through which said lever-bar works, and also with a depending stop-lug above the opening adapted to engage the lever-bar, for the purposes set forth.

In testimony whereof we hereunto aflix our signatures, in the presence of two witnesses, this 18th day of August, 1900.
