4 Claims. (01. 221-27) I This invention relates to improvements in pouring spouts, particularly spouts that are adapted. to be retracted into the container for protection during shipment and handling.

One of the objects of the invention is the provision of a spout construction of this character which shall have a rigid mounting in the container when it is in extended or operative position.

Another obect of the invention is the provision of a mounting for the spout such that the joint between the container and the spout in the operative position of the latter shall be a metal to metal one of a nature such that a good sealing of the joint is effected. p 1

Other objects and features of novelty will appear as we proceed with the description of that embodiment of the invention which, for the purposes of the present application, we have illustrated in the accompanying drawing, in which Fig. 1 is arrelevational view of a metal pail in which the invention is incorporated, the pail being shown resting upon its side, parts of'the pail being broken away and other parts shown in section in order to more fully illustrate the invention.

Fig. 2 is a fragmental cross sectional view on a larger scale, showing the spout in retracted or inoperative position.

Fig. 3 is a view similar to Fig. 2, but with the spout in extended or operative position.

Fig. 4 is a fragmental plan view looking down upon the head of the pail, the spout being shown in extended position, and

Fig. 5 is a perspective view of a modified form of the spout.

In the drawing we have shown at it a metal pail of more or less conventional form intended for the packaging of oil, alcohol and various other liquid materials. This pail is illustrated in the drawing in pouring position, its normal position being upright. At one end the pail proper is open, itsedge being finished with a bead ii. when the pail is filled with liquid this open end is closed by a cover or head 52, also of sheet metal, which is removably securedto the barrel in any approved fashion, as for instance by means of tabs or lugs i3 which may be bent inwardly beneath the bead, a ring gasket it being thereby compressed between the bead and the outturned flange it of the head, sealing the container.

In the head it, preferably near the rim thereof, we form a circular opening in which is mounted a collar it, preferably by means of a lock joint ll. This collar is so formed as to takea closing cap,

for example the collar may be provided with an encircling groove 18 adapted to receive the flexible inwardly bent edge of a resilient metal cap I! provided with a gasket 20 for engagement-with a circular seat 2| on the collar.

The collar structure comprises an inner sleeve 22 which is separated somewhat from the outer wall of the collar. This sleeve is circular in cross section about an axis which extends at an angle v to the main axis of the collar and the axis of the pail likewise. at the inner end ofthe sleeve there is a band, indicated at 23, which is flared, that is to say it is tapered away from the inner end. This flare or taper is relatively small, for example twenty thousandths to the inch'. The band 23. however may be considerably less than an inch in. width. The sleeve 22 is preferably formed of metal tubing flanged at its outer end and soldered, welded or otherwise permanently and rigidly Joined to an inwardly extending flange 26 on the remaining portion of the collar l6;

In the flange 26 of the collar between the sleeve 22 and the seat 2! we form an opening 24 which serves as a vent opening. A vent tube 25 is soldered or welded to the collar within this opening, and extends for a short distance inwardly in a curve alongside the sleeve 22 and thence in a straight line beneath the head l2 of the pail to a position near the rim upon the opposite side of the center of the head. The vent opening is of course closedwhen the spout is retracted and the closing cap I9 is in place, as illustrated in Fig. 2.

The pouring spout 21 is generally cylindrical in form. Its outer end is preferably cut at an angle so as to be parallel with the pail head, and it may be reenforced by a rebent edge 28 if desired. The lower part of the forward end of the spout has a lip 29, the purpose of which is to prevent liquids, particularly liquids that are highly fluid, from backing up onto the exterior surface of the spout. This lip 29 also serves as a stop when the spout is pushed into the sleeve 22, as indicated in Fig. 2.

The spout 2'! is formed from a sheet of thin gauge metal which is flanged along its longitudinal edges and rolled up to bring the flanges together, after which the flanges are joined by solder, forming a longitudinal internal rib along the top surface of the spout. 'I'hlsrib at the forward end is enlarged and perforated transversely. The ends of the wire ball 3! are mountr ed in this perforation. Ball 3! is formed of, somewhat resilient material which is so shaped that in its natural condition the ends are crossed. Near the ends also there are formed small re verse bends 32 which bear against the sides of rib 33, Because of the resilience of the bail,

these reverse bends 32 provide friction surfaces that by engagement with the rib 30 tend to hold the bail 3| in any adjusted position. Hence when 5 the bail is swung out and used as a finger hold for pulling the spoutout to operative position, the bail remains in its outwardly extended position, indicated in Fig. 3, where it is out. of the way of the liquid when lO'the container.

The metal of the spout is preferably of somewhat lighter gauge than that of the sleeve 22, and at its inner end it is flared or reversely tapered with the same degree of taper as the band 23, and this flared portion of the spout is marked 33 on the drawing- The flared portion 33 may be a trifle wider than the flared band 23. The inner extremity of spout 21 is not reenforced in any manner, and accordingly its natural resilience is not interfered with. It-may therefore conform very readily and effectively with the flared band 23 when the, spout is pulled out to operative position. In Fig. 5 we have illustrated a spout of slightly 25 modified form, having a cylindrical body 21 and an inner flared band 33. In this form the metal of the spout at the pouring end is pinched inwardly to some extent, as indicated at 34 and 35, leaving a narrow pouring groove 36, which is useful when the liquid in the pail must be transferred to small mouthed bottles or other containers. In thus forming the groove 38 we take precautions to prevent the inward bending at the points 34 and 35 from forcing the metal of the groove outwardly, as the spout must be capable of being fully retracted to the position shown in Fig. 2.

In order to take liquid from-a pail or drum equipped with the spout of this invention, the operator first removes the cap it from the pail while the latter is sitting on its bottom end. He then grasps the bail 3| and pulls the spout 21 outwardly to the position of Fig. 3. As soon as the flared 'or tapered portions 33 and 23 of the spout and sleeve come into tight engagement, further movement is of course stopped and the Joint between the spout and the sleeve is then liquidtight. It is also rigid and secure. Rigidity is eifected not only by the engagement of the flared portions, but also by the engagement of the cylindrical portion of the spout with the cylindrical portion of the sleeve. This latter engagement, while not liquid-tight, is close enough to provide. an excellent mechanical connection.

There results a spout mounting which is firm and secure and capable 'of resisting all forces naturally to be encountered except force applied the latter is poured from inwardly along the axis of the spout. The rigidity of the spout mounting is suiiiciently good to permit supporting the filled container upon its spout during the pouring operation. In so far as the sealing effect is concerned, there is no dependence upon gaskets, which sooner or later become leaky, and the metal to metal flared bands, if carefully formed, produce an entirely liquidtight connection.

Variations from the described structure may be employed. Accordingly we desire it to be understood that the scope of the invention is to be regarded as defined exclusively by the appended claims rather than by the foregoing description orthe accompanying illustration.

Having thus described our invention, we claim:
