ing from the can;" y I Second; to provide an attachment of this class with means for puncturing the can at the top for venting and also for pouring therefrom-and is not in use for pouring;

Fourth, to provide an attachment of this class which covers the can and so forms the can pourinllipout so that the contents of the can will" 25 not or run down between the casing and the can? Fifth; to provide an attachment of this class.

which is readily applied and secured to the can or removed therefrom;

30 Sixth. to provide an attachment of this class in the form of a pitcher with a handle for sup-f porting the can so that the can is entirely enclosed; v 1

Seventh. to provide an attachment of this class in which the can puncturing and forming members are sharp with keen edges so that the can is and not broken when punc-" punctured and cut turing the same; 7

Eight, to provide an attachment of this class' which maybe made of very thin metaland oifset. or'eorrugated. to reinforce the same: and

which isvery simple and ecdhornical of construction, easy to operate,-efllcient in its action and which will not readily deteriorate or get out of order. 7 i p With these and other objects in view as will appear hereinafter, my invention consists of 'cer-'.

Similar characters of referencerefer to similar parts and portions throughout the several views of the drawing.

Themain can casing I, handle 2, casing screwgo bottom 3, puncturing and closure lever'l, can puncturing and spout forming lug'5, vent puncturing lug 6, spring 1, and lever support 8, constitute the principal parts and portions of my milk can opening forming andpouring attachment. a V

i The main can casing I is cylindrical in formv and closed at its top or upper end and is adapted to fit the can when placed therein but permits the easy slipping of the can into the same. It

is screw-threaded around its lower end on which is adapted to screw the casing screw bottom 3 so that the can. is entirely enclosed therein. This casing is provided at the front upper side with an enlarged oii'set portion Id, asshown best in Figs. 1 and 3fo'f the drawing, which is adapted to permit the turning of the formed spout in the can to a position where itwill'enter enlarged longitudlnal portions lb depending uponthe direction it is'turned to facilitate the removing of the cas- 40 I ing.fromthe can. It willbenoted that the por- Ninth, to provide an'attachment of this class tions lb arecut away at the bottom leaving slots in the casing I at the bottom over which the screw bottom extends when it isin pQSitiOILBS .shown in Fig. 1 of the drawing. The casing i is "also provided withreinforcing ridges or corruga- ;tionsf lc at its side. The casing l is also provided with openings id and le to permit the can puncturing lugs to pass through for puncturing and forming the can. The casing is provided at its normally back side with a handle 2' which is adapted to facilitatethe handling of the casing with the can during the pouring operation and otherwise.

Secured to the back side of the casing immedi- 88 ately above the handle 2 is the lever support 8 which is a channel member and bifurcated at its upper end. Between the bifurcated portions the lever 4 is pivotally mounted on a pin Ba. Secured through the members of the channel of the lever support 8 is another pin 8b on which is mounted a coil spring I which is provided with extended ends, one extending end engaging the extended end 4a of the lever 4 and the other end resting against the surface of the support 8, thus supporting a coil spring means for tending to cause the lever 4 to move downwardly at the puncturing end, the portion 4a forming a handle which is adapted to be grasped by the thumb of the user for raising and lowering the lever 4 relative to the casing l. Secured to the lever 4 adjacent the support 8 so as to engage the side of the can through the opening le is a vent puncturing lug 6 which is preferably a round very sharp pointed relatively small lug for providing a vent in the side of the can towards the handle. At the'opposite end of the lever 4 from the handle 4a is a downwardly extending lug 5 which is provided with a very sharp edge 5a which is adapted to puncture the can close to the front edge thereof. It is'provided with a forwardly tapering portion 5b ,which is adapted to press the edge of the can outwardly forming a pouring spout, as shown best in Fig. 6 of the drawing. This upper edge is again forced outwardly past the side of the main portion of the casing i so that the contents of the can will not run down of spill down between the casing and can and will a readily pour from the can when the lever 4 is lifted out of the way by pressure of the thumb on the portion 4a of the lever 4.

It will be noted that the front portion of the lever 4 at its upper side is preferably rounded at 40 at the sides so that the spout formed in the can is rounded and extended.

It will be noted that the lugs 8 penetrate the can first, then the lug 5 begins penetration of the can after the penetration of the lug 6 so that the can is initially punctured at different times so that less pressure is required for puncturing and forming the can for pouring purposes.

The operation of my attachment is asfollows: The casing screw bottom 3 is removed from the casing l by screwing it off and a can is positioned in the casing I. Then the bottom 3 is screwed onagainst the bottonrbf the can holding the can rigidly in position in the casing. Then the casing is placed on its bottom and pressure is brought to bear on the lever 4 which causes the lug 5 first to enter the side of the can, then the lug 5, thus providing a vent at onefside and a pouring spout in the can at the opposite or front side. pouring purposes. By taking hold of the handle 2 the user presses the thumb on the end 4a of the lever 4 depressing the same and the hole is tilted forwardly the same as a pitcher for pouring from the can, after which the portion 4a. is released and the spring 1 causes the lever 4 to move downwardly whereby the lugs 5 and 6 enter the openings in the can and they are quickly Then the can is ready for use for sealed by the milk around the small opening and may be thus used until the can is empty. In removing the can the bottom I is removed, then the can turned in the casing i until either of the enlarged portions lb is reached and the casing then taken from the can.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a milk can opening forming and pouring attachment, a casing substantially closed at its upper end and open at its lower end for receiving a can and provided with an enlarged offset por tion at its front upper side, a handle therefor, a lever pivotally mounted on said casing adjacent said .handle and provided with a handle extending portion, and a spout forming lug forming the free end of said lever, said spout forming lug consisting of a sharp pointed-member provided with an upwardly diverging forwardly extending wall adapted to engage the side upper edge of the can and distort itoutwardly against said enlarged offset portion. 1

2. In a milk can'opening forming and pouring the can and distort it outwardly against saidenlarged offset portion, said forming lug provided with rounded portions at its upper front side. a

3. In a milk can opening forming and pouring attachment, a casing substantially closed at its upper end and open at its lower end for receiving a can and provided with an enlarged offset portion at its front upper side, a handle therefor, a lever pivotally mounted on said casing adjacent said handle and provided with a handle extending portion, a spout forming lug forming the free end of said lever, said spout forming lug consisting of a sharp pointed member provided with an upwardly diverging forwardly extending wall adapted to engage the side upper edge of the can' and distort it outwardly against said enlarged oifset portion, said forming lug provided with rounded portions at its upper front side and a vent puncturing lug secured to said lever near its pivotal mounting.
