7 Claims.'

The invention relates to new and useful improvements in a can opening and spout forming device which may be utilized for forming a pouring opening in a can end and the shaping of the can body wallso as to provide a pouring spout which is associated with the opening and through which the contents of the can may be dispensed.

Eiorts have been made to provide a can .with

an opening and to shape the body wall adjacent the opening so as to provide'a pouring spout. In

all such devices, the opening and spout are formed in one operation, or'substantially simultaneously,

and therefore, it is dilcult to operate such a device. l A

An object of the present invention is to provide a can opening and spout forming device which is so constructed that the can end may be first severed, and after which the body wall of the can shaped to provide a spout.

A further object of the invention is to provide a device of the above type which may be positioned on the can end, and while held in place, the can end severed and the body wall shaped to form the spout.

These and other objects will in part be obviou and will in part be hereinafter more fully disclosed.

The invention resides in a can opening and 50 spout forming device which includes a base inemberfadapted to be positioned on the top of the can so as to rest on the double seam. This base member is providedwith offset lugs at opposite sides thereof, and one pair of the lugs engages 55 the double seam at the inner'face thereof; while the other pair of lugs engages the double seam at the outer Vface thereof, and these lugs, therefore, prevent the base member from moving endwise on the can while it is held in contact therewith. The base member has attached thereto a cutter for severing the can end. This cutter has a depending blade providedwith a piercing point and cutting edges diverging from the piercing point. The lugs are placed in contact with the double seam, with the point of the cutter contacting with the can end, and then the base plate is forced to a horizontal position, orl into contact with the can end, and this will force the cutter through the can end, severing the can end and rolling the same back so as to form a dispensing opening. The cutter pierces the can end adjacent theJ double seam, and as it is lowered it will cut the can end along lines extending inwardly from the double seam. After the end has been severed and while the cutter is still in the opening, the spout forming member, which is mounted on the base member, is brought into contact with the double seam at the inner side thereof. This spout forming member has means associated therewith for producing a lateral pressure against the inner face of the double seam so as to force the double seam and the body wall adjacent thereto outward, and thereby form a pouring spout which is associated with the dispensing opening.

Referring more in detail to the drawings, the invention is used for severing a can end and forming a pouring spout. The can body is indii vention has to do particularly with a can opening and spout forming device for opening a sealedcan and preparing the same for dispensing the liquid content thereof. Lubricating oil for automobiles is being marketed in sealed cans of the type above referred to, and the present invention has particularly to do with a device which may be quickly used at the oil filling station or in a garage for opening and preparing the can for the dispensing of the lubricating oil therefrom. The can opening device includes a base member or plate 4 which is of considerably greater length than the diameter of the can. Said base member is provided with oiset lugs 5, 5 which are cut from the plate and bent downward, so that when the plate rests on the double seam, these lugs will extend `down into the usual recess in the can end and, 4'IQOntaQt with the inner face of the double seam. The plate is also preferably provided with spaced lugs 6, 6 which will engage the outer face of the double seam. The purpose of these lugs .is to hold the base member in a fixed longitudinal position and for preventing the base member from sliding endwise on the double seam during the operation of the severing of the can end and the forming ofl the s pout. The base member, as shown in Figures 1 and 2, is provided with another set of lugs 5a, 5a, and an associated set of lugs 6a, 6a which are similar to the lugs 5 and 6. The purpose of the second set of lugs is for vuse in connection with a can of a larger diameter, as Awill be referred to more fully hereafter. Fixed to the under side of this base member or plate 4 is a cutter including a shank '7 which is welded or otherwise attached to the base member 4,' and a blade 8 which extends substantially at right angles to the base member 4. Said blade 8 is provided with a piercing point 9 (see Fig. 3) and cutting edges 10, 10 which diverge from each other and terminate in the piercing point. When it is desired to open a can, the base member 4 is applied to the can so that the double seam 3 thereof lies between the lugs 5 and 6. 'This will place the piercing point of the cutting blade in contact with the end close to the double seam atV the opposite side of the can body. The operator presses down on the base member, holding the same in contact with the double seam, and also presses down on the outer end of the handle portion 4a which is a part of said base member. This will force the. cutter down through the. can end, severing the can end along lines extending from the point a where the piercing point initially While thev cutter is still in ,the opening, as

shown in Fig. 4, the spout forming devices are operated to shape the double seam and the body` Wall adjacent thereto into a. pouring spout. This spout forming device, as shown, consists of a ,spout shaping member'12 which ispivoted at -v13 to a supporting link member 14. -This link member 14 is in turn pivotedA at 15 to a lug 16 formed from the base memberl 4. Said base spout forming member 12 carries a nger 17 which is adapted to engage the upper face of the double seam centrally of the opening formed by the cutter. Said spout forming'member is also provided with a shoulder18 which is brought into register'with the' inner face of the double seam centrally of the opening. There is 19 which is coiled about the pivot 15 securing the link member 14 to the base member 4. One

arm of this spring 19 engages underneath the link member 14and the other arm engages the upper vface of the base` member 4.I This will normally hold thevlink member 14- raised to a set position, and in this set position,the spout shaping member `12 is set so that the shoulder 18 will be placed just inside the doubleseam. The upward movement of the member 12 through the action of this spring 19 is` limited by a lug 19a. This lug 19a is struck up from the member 12. The member12 extends through a. slot 4b in the base member 4 and the lug 19a is offset to one side as clearly shown in Fig. 7, so that it engages the under face of the base member 4. Mounted on the pivot 13 is a U-shaped plate 20 which serves as a hand rest on which the operator may press to force the joined ends of the link member 14 and the spout forming member 12 downward from the position shown in Fig.

4 to the position shown in Fig. 6. When these members are forced downward, the shoulder 18 will contact with the inner face of the double seam. The lugs 5, 5 will prevent any longitudinal movement of-the base member 4, and therefore, the double seam and the can body wall just below the same will be forced outward and shaped into a spout. The double seam is bent outward from the points d, d to the point e which is the end or nose of the spout. This bending of the side wall and the spout outward will contract the portions of the can in the region of the opening formed by the cutter and will distort slightly the side walls b, c of the opening.

From the above it will be apparent that a canl .opening and spout forming device has been provided wherein the opening through the can end is formed and completed, after which the parts of the can in the region of the opening are shaped to provide a pouring spout. tributes the power or force necessary to operate This disthe device so that it may be readily manipulated lby hand for the producing of the opening and thek forming of the spout. f Y

It is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the Yap- `double seam in the region of thev opening for I forcing the can wall and the double seam outwardly and shaping'. the same into a pouring spout. v Y
