To all whom mag/concern:

. Be it known that 1,. GEORGE A. WILLIAMS,

' a citizen of the United States, residing at Watertown, in the county of Litchfield' and State of-Conneeticut,-have invented a cer-. tain new anduseful Improvement in Metal- Can Nozzles and Closures Therefor, of

which the following is a full, clear, and

exact description, reference being had to the accompanying drawings.

This invention relates generally to metal cans and more particularly to a nozzle and closure for the same.

Heretofore metal cans havebeen provided with comparatively short nozzles and consequently great difficulty has been experienced in pouring the liquid from the can through the said.nozzle, and in some instances supplemental devices have been attached to the nozzle'proper to facilitate the pouring operation.

Various 'forms of nozzle closures have also been employed inconnection with the aforesaid short nozzle, but all such closures re-' quire the use of a machine-or tool in applying the same, and after the closure has once been removed it is impossible to replace the same upon the nozzle and properly reseal it.

One of the objects of my invention, there fore, is to provlde an elongated nozzle which will greatly facilitate the pouring of the liquid from the can, such nozzle being of such construction as to prevent bubbling or foaming at the mouth of the nozzle and another, object of the invention is to pro vide a nozzle and closure therefor of such construction that if desired said closure can be applied by hand. and a perfectly tight seal obtained; and furthermore this. closure is of such nature, and cocperates with the nozzle in such a manner, that it can be easily removed and replaced,fand the opening and closing operations repeated as often as desired without impairing the tightness of the seal. Y

Another desired, be applied by machine or tool.

With. these va'rious ob ects. in view the invention consists in the novel features of construction hereinafter fully described and pointed out in the claims;

In the drawings forming a specification Figure 1' is a perspective view showing the upper portion of a can provided with in novel construction of nozzle and closure;- ig. 2- isa side elevation of the upper portion of the can, the closure being removed from the nozzle; Fig. 3 is a detail perspective view illustrating the nozzle with the closure removed; Flg. 4 is :1

part of this I detail sectional view' showing the nozzle,

with the closure sealed thereon; F i 5 is a sectional view on the line 5--5 o Fi 4 looking in the direction of the arrow, igs. I

6 and 7 are views illustrating the manner of sealing the "closure upon the'nozzle, and- Figs. 8, 9, 10 and. 11 are modified forms of nozzle.

Referring. to the drawings A, indicates the metal -can, l3, the nozzle and C, the 010- sure therefor. The metal, can; may be of any style or shape and of any desiredsize. The nozzle is of considerable, length as com- .paredwith nozzles heretofore employed and maybe described as elongated; this nozzle being secured in the head of the can in the usualmanner, and at-its extreme outer end it is rolled over, preferably inwardly and downwardly as indicated at 10, thereby somewhat contracting the dischargemouth.

Directly below'the outer'o upper end of the nozzle, the sides are made inclined or Q tapering as shown'at- 11, and are then swelled outwardly as shown at 12, and at the end of said swelled portion 12, is reduced an annular exterior shoulder 13. he

end of nozzle may be rolledover outwardly and downwardly as shown in Figs. 10 and 11 providing a rounded but an unobstructed mouth. From theshoulder 13 to the head of the can thenozzle is very'sli'ghtly tapered so as to.allow the. drawing punch to be withdrawn.

It will be noted, therefore, that looking at the nozzle from the interior there is a slight contraction just above the annular shoulder I that the liquid is first contracted "slightly '13 and then there is an expansion providing the annular space 14, and then the further contraction "due to the rolling in of the extreme end of the vnozzle.

5 In "pouring liquid'from the canthe unusual length of the' nozzle has been found highly beneficial, and the-formation of the nozzle upon the interior above the annular shoulder ,13 permits pouring the contents in a steady unbroken manner, due -to the fact and \then permitted to expand into the annularv space 14 and. then be discharged ed month which has the ieflect of completely eliminating the bubbling and frothing, com- 'mon with the short wide nozzles incom 'mon use.' For the purpose of tightly closing and sisting of a slotted apron to which'is connected a contracting ring 20, and to the ends of this ring is connected the lever 21 which is so constructed as to contract the ring when said lever is thrown, down to its locked position, thereby securely bindingthe cap upon the end of the nozzle, and the inclined portion 11. of the nozzle facilitates this binding action.asthe'contracting ring is drawn down'upon the inclined or-tapered portion i as'it is'contracted by'the lever, and as the cap has-a suitable sealing liner or filler 22,

for engaging'the support 23 which consti- 40 tutes a part ofthe machine or.to'ol used during the sealing operation, said support being shown in dotted lines in Fig. 6 resting directly beneath the annular shoulder 13 thereby relieving the .head of the can of pres- 5 sure during the sealing operation, it being understood that any suitable means may be em il oyed for throwing the lever down, and in igs. 6 and 7 I have shownin dotted lines a rotating finger capable of accomplish- 5 ing the proper-movement of the lever, said rotating finger being operated by any suit-,.

able mechanism. z

' It will thus be seen that the annular shoulder 13 performs the double function of serv-i ing as a fulcrum-for the clamping lever and also as a means for supporting the nozzle and relieving the head of the can from pressure during the sealing operation.

. While I have shown one particular type ..60 of cap and fasteningmeans to be used as a closure in'connection'with the novel form of nozzle, it is obvious that other forms of closures may be employed, provided they have a contractible and expansible skirt,

- through the inwardly contractedand round sealing the nozzle I employ a cap 0 (con-- together with means for contractingv and fastening the same upon the end of the nozzle. I I

Having thus described my invention, what I claim is 1, In a metalcan, a nozzle having its extreme outer end rolled inwardly and down wardly and spaced from the sides of said nozzle, said-nozzle also having an exterior annular shoulder adjacent the upper end thereof. i

2. A metal can having an elongated nozzle'the extreme outer end of which is rolled inwardlyand downwardly and-spaced from the sides thereof, an exterior annular shoulder adjacent the outerend' of said nozzle, the sides of said nozzle below'the inwardly rolled end and above the exterior shoulder 'beingitapered. inwardly and downwardly.

-3.- A metal can having an elongated nozzle, the extreme'outer end being rolled inwardly and downwardly, said nozzle having an" exterior annular shoulder adjacent the, outer end thereof, the sides of the nozzle between the inwardly rolled end and the shoulder being inclined first inwardly and then outwardly.

'4. In a metal can, the combination with a nozzle, the length of which is in excess of its diameter, the discharge end of said nozzle being rounded inwardly and downwardly. and spaced from the sides thereof,

said nozzle having an exterior annular shoulder adjacent its outer end, of a detachable, expansible' andcontractible closure adapted to befitted upon the outer end of said nozzle and secured by contracting said closure upon the same.

5. A nozzle .for containers, made of 'a single piece of sheet metal formed with a pouring opening and below said opening with an outward projection adapted'to support said nozzle against sealing pressure,- and formed with an inwardly bent circular portion between said opening and said projection; whereby a gasket may be tightly seated with pressure by. the aid of said projection and said pressure maintained by the aid of said inwardly bent portion.

. '6. A nozzle for containers, made ofa single seamless piece of sheet metal formed with a'beadedlipand with an outwardly bent'bead constituted of two thicknesses of metal flattened together, and formed with an inwardly bent circular portion between said lip and said flattened bead; whereby a gasket may be tightly seated with pressure by the aid of said bead'an'd said pressure maintained by the aid of said inwardly bent portion.

7. A sheet metal nozzle for containers,
