CAN OPENER.

Appfication filed. April 23, 1923, Serial Our invention relates to improvements in can openers and one object is the provision of a device which can be operated with ease and rapidity by any one to remove the entire top of the can to allow instant discharge of the entire contents of the can.

Another object of our invention is the provision of a can opener which in addition to removing the entire top of the can to allow discharge of the whole bulk or contents ot the can and insure a saving of a portion 01' such contents, will be oi? sucl simple, cheap and durable construction as to make its use a practical necessity.

To attain the desired objects, our invention consists of a can opener embodying novel features of construction and combina tion of parts, substantially as described and defined by the claims, and as shown in the accompanying drawings, wherein Figure 1 is a side elevationot our can opener, the parts being in the position they occupy before the cutting operation begins.

Fig. 2 is a similar view with the parts in the position they assume during the opening or cutting action. I

Fig. 3 is a top plan view of the can and device, showing the path or slit.

Fig. 4- is an end View of the can open, with can in elevation.

Figs. 5 and (i are detail views of important parts of our can opener.

Our invention consists of a rod 1, which has a curved point 2, at one end while the other end is bent or formed into a handleloop or link 3. Located on the rod 1, is a clip or bracket 4-. of the form shown and adapted to slide loosely on said rod. The handle-looped end 3, ot the rod 1, terms the lower handle of this device which operates somewhat like a pair oi pliers or tongs. 'llhe upper-handle 5, is formed from a rectangular piece of sheet metal, and is bent longitudinally into the form of an inverted ll-shape. This upper handle 5 is connected at the lower edge of one end to a jaw 6, by means of th rivets 7 and 8. The jaw 6 has an extension 9, in the form of a stud on which is located a small roller 10, which is adapted to revolve freely on said stud. 'this jaw and upper handle are hinged or pivoted to the lower end 11, oil? the clip or bracket 4, by means of the bolt 13, which No. 633,912. Renewed January 5, 1926.

passes through a hole in the jaw 6. and also through the ears 11 and 12, which form hearings for the ends or said bolt. The upper Ushaped handle 5, is adaptedto house or enclose the lower looped handle 3. Located on the rod 1, and in the clip 4C, is arotary cutter 14, which has a. blade 15, in the form 01 a circular disc which is connected to a hub 16, on which is a flange 17. This flange terms a groove 18, between it and the blade 15. When in operation, this groove 18, its over the rim of the can and acts as a guide to hold the cutter in proper relation to the rim of the can.

Connected to the lower handle 3, is a flat spring 19, which extends up into the upper handle 5., as shown in (Fig. 1). The object of this spring is to hold the handles 3, and 5, normally in open relation to each other so that the device can be easily applied to or removed from the can.

The operation is as 1EOllOWSZ-Tl1G curved point 2 is inserted at the center into the head of the can. Then the cutter is adjusted so that the blade its just inside of the rim 20, and rests on the head of the can. While in this position, the small roller is located directlv under the rim ofthe can. Then by a grip of the hand on the handles 3, and 5, they are brought together which forces the roller 1011p against the under side of the rim 20, and by a counter force the blade 15 is driven down through the head 01 the can, while the rim is forced up into the groove 18, which forms a guide that holds the cutter in fined relation to the rim of the can and causes the blade to cut or shear the head just inside the rim as shown in Fig. 2. then the can is held by one hand while, with the other, the opener is swept around the head of the can, the roller 10 rolling around under the rim while the blade cuts the head out close up to the rim.

It will be noted that the handles 3 and 5 operate after the manner of a pair of scissors in bringing the roller 10 and cutter or blade 15 in operative position, thus holding the roller and cutter in the best possible position, and this forms a most imortant teature of our invention.

W hen the operation is complete the grip is released on the handles 3 and 5, when the spring 19 torces them to the open position so that the device can easily be removed from the can, the curved point 2 lifting the severed top out.
