CAN POURING APPLIANCE. I

Original Filed June 1'7, 1955 INVENTO? Patented Oct. 6, 1936 UNITED STATES PATENT OFFICE CAN POURING APPLIANCE n bra, Calif.

Application J une 17,

Renewed 1 Claim.

This invention relates to devices used for punching sealed cans for drawing liquids therefrom by means of suitably shaped parts of the devices.

One of the objects of this invention is to provide a device that can be applied by quick lever action to make it ready for the pouring.

Another object is to provide means whereby air will be shut oil automatically by action of the spring that controls the pouring or spout shutter.

Another object is to provide a device so designed that it will stay clamped to a can by the very movements in pouring liquids from the can.

Another object is to provide a simplified structure that is at the same time sturdy and easily handled.

Other objects will appear from the following description and appended claims as well as from the accompanying drawing, in which- Fig. 1 is a fragmentary vertical section through the device in a position as it appears when applied over the top of a can, showing also in dotted lines the position of the handle for and preparatory to clamping the device to a can, and also the position of the discharge mechanism in open position in dotted lines.

Fig. 2 is a fragmentary side elevation partly broken away of a slightly modied form.

As illustrated, a cross bar 3 serves as a support or mounting for the other parts of the device, at the same time having the hook-end 4, to engage over one side of a can while the bar is placed over the top of the can. 'Ihe opposite end 5 is provided with lugs 6 with a pivot l, by which the handle 8 is swingably mounted on the bar 3 for engaging over the opposite side of the can.

At the end t there is a spout 9, extending outwardly from the bar 3, and from the spout extends a conduit or passage II)` provided in a pointed punching member I i, of which the pointed end projects inwardly.

The pointed member il is so designed that a can, when placed sidewise against the member il, can be punched at such a side by means of lever action on the handle 8 forcing the can towards and over the member' I I.

A lever-end I2 is provided on the` handle 8 and the lever-end is designed with a shouldered portion I3, adapted to engage over the opposite side of the can and so that, when the handle is pressed downwardly, the engaged can is tilted upwardly, iirst, so as to cause the punching of the opposite side bythe member II, and, as the can moves 1935, Serial N0. 26,914 July 1, 1936 further upwardly, so as to cause a punching of the top of the can for an air-vent.

From the bar 3 projects for this purpose a second punching member I4 with a pointed end poised so that it will force itself into the top of the can as the can is moved into its proper pouring position, this member I4 being also provided with a passage, indicated at I5, extending upwardly through the bar 3, forming the airlo vent.

A control lever I6 is pivotally on the top of the bar 3 having at one end a closing member or portion II to t snugly over the spout 9 for .keeping the spout and thereby any attached can sealed when not handled for pouring purposes and having at the other end a handle member I8.

For keeping the control device in a closed position, a spring I9 is iirmly secured to the underside of the handle member I8 and the spring is formed so as to come with its end portion 20 to rest over the passage I5 in normal closing position.

When a pouring is desired from a can held in this device, the handle member I8 is pressed downwardly against the tension of the spring I9 so as to lift the closing member I1 to the position indicated in dotted lines at Ila, freeing the spout 9, at the same time the spring I9 is compressed to bring the end 2li to an upwardly tilted position indicated at 20a, so that air can enter through the passage l5 that is thereby made free at the same time when liquid is drawn from the spout 9 through the hollow punching member I I. The air-vent I5 is automatically closed by the spring returning to its normal position when the handle I 8 is released for closing the spout 9 by the member Il.

8a indicates the position of the lever 8 when in the position for catching a can for forcing the can to be punched and moved into engaged position, a portion of a can being indicated at 2l in a position preparatory to being forced against the punching members and preparatory to being moved into engaged position, the engaged position of the can being indicated in dash-dotted lines at ZIB.

In Fig. 2, a slightly modified form is illustrated, especially suitable with cans that are commonly fully emptied after once being punctured or opened, as, for instance, with sealed oil cans; while the device illustrated is preferably used with cans that are emptied from time to time, such as milk cans.

In this modified form, the cross bar 22 is preferably made of heavy steel with a hook-end 23,

provided with a suitably long tube 24. The opposite end 21 is provided with pivot 26. y A handle 25 is swingably mounted in a similar manner as with the device illustrated in Fig. l.

Being of steel, vthe punching member 28 is readily stamped out of the material of this bar, as will easily be understood from the illustration.

In application, this device is handled in a similar manner as described with reference to Fig. 1. A can is firstapplied in a tilted position to be caught on the punching end of the tube 2l and is then forced upwardly until the top of the inserted can is punctured by the punching member 28. A tearing of a hole forthe air-vent is all that is necessary with cans that are to be handled with this device, while with the device of Fig. 1 suitable sealing around the punching members can readily be provided for, as will readily be understood from the illustration. Y

Having thus described my invention, I claim:

In a can appliance of the class described, a member forming a support and designed to rest over the top of a can having a portion extending downwardly from one end for engaging over one 25 side of the inserted can and having a pivoted member at the opposite end for engaging the opposite side of said can, a. punching member disposed in the mst-named end poised to puncture the adjacent side oi' the inserted can and having a-passage extending outwardly, a handle swingably mounted on the-pivoted member and having a lever portion to engage over the opposite side of the can and designed to force the can against the punching member and move the can into pouring position, a second punching member in the support having the punching end extending downwardly so as to become eiective when the can is forced into pouring position and being provided with a passage, and a control device swingably mounted on the top of the support with one end formed as a closing member for the first-named passage and the other end formed as a handle, and a spring disposed between the handle and the second-named punching member so as to rest on the second-named passage for closing this when the device is in closing position, the spring being designed and arranged so that it automatically tilts so as to free the second-named passage for an air-vent when the spout control device is moved to the pouring or open position.
