SPECIFICATION forming part of Letters Fatent NO. 586,874, dated July 20, 1897.

Application filed July 30, 1896. Serial No. 601,022. (No modelJ To all whom it may concern: tical member 10. The foot 11 is pointed and Be it known that I, \V ALTER A. SIMOND, of its upper surface is usually made flat, so that Tilton, in the county of Belknap and State of it may engage readily against the under face New IIampshire have invented a new and of the head of a can into which the pivot-sec- 55 useful Improvementin Can-Openers,of which tion may be introduced.

The object of my invention is to construct Ayoke 1S ismounted to slide upon the stem, a can-opener of the central-pivot type comand the rear member of this yoke is enlarged 60 IO prising but few parts and provided with a where the yoke passes through it and is of cutter capable of being readily and convensuch length that it may extend downward beiently adjusted to open cans of different diyond the stem, and the lower extremity of ameters, the cutter always opening the canthe longer member of the yoke is shaped to top at the same distance from the side edge, form a spur ll, which is to engage with the 65 15 no matter whether the can be large or small outer side face of the can and form a guide in diameter; and a further object of the infor the cutting portion of the opener.

Fig. 3 is will be brought to an engagement with the a section taken substantially on the lines 3 3 outer side face of the can, as shown in Fig. 2. of Figs. 1 and 2; and Fig. 4. is a side elevation The yoke l5, as illustrated in Fig. 4, may of a portion of the opener, illustrating doube made of suflicient size to accommodate 4o ble cutters, one being interchangeable with two cuttersnamely, the cutter 18 above rethe other. ferred to and a cutter 18, the hubs of which In carrying out the invention a main stem are usually placed end to endand the rear A is employed, which is preferably circular cutter 18 will not engage with the can, being in cross-section, and the said main stem is located in a dip or loop 10 formed in the provided at its outer or forward end with a longer member of the yoke, and when the pivot-section B, the said pivot-section comlarger form of yoke is employed the guideprisinganiember 10, which is projected downspur 14 will be in advance of the rear cutter, ward at an angle, usually a right angle, to the sustaining the same relation to the forward stem A, and a foot 11, which is given parallel critter as the spur shown in Fig. a does to the too 50 position with the stem yet extends forwardly single cutter. hen the forward cutter bebeyond it and at a right angle to the vercomes dulled, the handle 12 may be removed and the two cutters taken out, and in replacing the cutters the rear or auxiliary cutter will be placed at the front.

It will be observed that this device is exceedingly simple, durable, and economic, and that when its pivot 13 is entered into the central portion of the top or bottom of a can and its stem A is pressed downward the cutter will enter the head of the can and will make a clean continuous cut around the entire circumference of the head, it being simply necessary to hold the stem A downward and at the same time give it a circular movement.

The arms 15 and their extensions serve when in engagement with the head of the can to prevent the cutter from dragging, permitting it to perform its work without any hindrance and likewise enabling a person to manipulate the entire cutter with the least possible exertion and without difliculty.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A can-opener having a main stem at one end of which is a pivot-point, a rotary cutter freely slidable and revoluble on the main stem, a yoke embracing the rotary cutter and having its arms perforated to slidably mount the yoke on the main stem, one arm of the yoke having a downwardly-extending guidespur capable of running around the outer edge of the can, and said arm of the yoke also having two oppositelyin'ojected lateral arms capable of running along the upper surface of the can to hold the yoke in a vertical position, substantially as described.

2. A can opener, having a stem with a pivot-point at one end, a yoke each arm of which loosely receives the stem whereby the yoke may move toward and from the pivot, and a cutter freely slidable and revoluble on the stem and inclosed by the yoke, the outer portion of one arm of the yoke being plane in a transverse line to rest said portion on the top of the can when the opener is operating and to hold the yoke in a vertical position, and a guide-spur projecting longitudinally from the lower end of the outer arm of the yoke and running in operation around the outer side of the can, substantially as described.

- A canopener, having a stem at one end of which is a pivot-point, a vertically-sustained yoke each arm of which has an opening receiving the stem, whereby the yoke is freely movable on the stem and a cutter slidable and revoluble on the stem and inclosed by the yoke, the yoke having a guide-spur projecting longitudinally from the outer arm of the yoke and running in operation around the outer side of the can, substantially as described.
