To all lwhom it may concer/n:

Be it known that I, CHARLES H. CAMP-y BELL, of Chelsea, in the county of SuffolkE and State of Massachusetts, have invented@ certain new and useful Improvements in; Cans, of which the following is a specifica-- tion. The present invention relates to Cans of. the sort which are commonly used for con= taining oils, varnish, etc., and which are; made of tinned4 sheet metal. Such cans are also frequently provided with pouringl spouts or lips surrounding the mouth. My object is first to construct a can of thischaracter with a nozzle havinga smooth opening which can be plugged,. and at the same timel provided withV an external threaded portion to receive a screwl cap; second to provide' a pouring spout or lip in connection with such nozzle, and third, to provide a construction of can having a pouring spout or 'lip which permits of tightv closing of the opening 'without difficulty.

In the accompanying drawings I- have illustrated a can embodying the preferred form of the improvements constituting my invention. Figure 1 is a plan view of a can top containing my invention. Fig. 2 is a cross-section on line 2--2 of Fig. 1. Fig. 3 is a side elevation showing the pouring lip in position for pouring. Fig. 4 is a cross-section on line 4-*4 of Fig. 2. Fig. 5 is a perspective view of the pouring lip. Fig. 6 isa perspective view of the screw of the can. Fig. 7 is a perspective view of the can nozzle.

The same reference characters indicate the same parts in all the figures.

a represents the body of the can and b represents the nozzle, that is the Haring mouth through which the can is filled and emptied. The nozzle may be made in the surrounding the mouth of the can bodyand lying outside of a lip c turned up around the mouth, to which it is soldered. The nozzle is of flaring shape and at its upper end is preferably provided with a iange (Z which is turned under to give stiffness. This nozzle is made smooth on the inside like' the ordinary can nozzle which is designed to be closed by a plug. 0n the outside of the nozzle is placed a shell e which has a lip f fitting tightly upon the outside of the flange d, while on its lower end the shell has a flange g which is 'turned inward and makes contact with the-walls of thel nozzle between the ends of the latter.

'The shell isformed with helical corrugations which provide the form of screw threads usually lemployed in .tin ware. Thesevthreads are adapted to receive a screw cap. Thethreaded shell is prevented from turning about the nozzle when the cap is rotated for the purpose of screwing it on and off by means partly of the tight fit between the lip f and flange d, but mainly by 'protuberances h which are bulged out from vthe walls of the nozzle and are contained in recessesz' in the flange g of the screwthreaded shell. It may be noted here that sake of brevity.

Surrounding the.nozzle is a pouring lip 7.2. which fits the screw e. One side of the lip isdrawn out to form a pouring channel for the liquid. Thelip maybe turned aboutthe screw so that its pouring channel projects over 'the' side of the' can .when it is t`o be used, or points inward when not in use. The threads of the screw e and neck portion la are so proportioned that when'the lip is turned into its pouring position it is raised to the mouth of the nozzle, being locked there by a flange' Z turned inward from the bott-omy end of the nelck. On the other hand when the lip is screwed down until the lower end-of the neck rests on the top of the can, the pouring channel is turned inward. In this posit'ion of the lip the threads of the screw are exposed, allowing a cap m to be placed upon the screw.

struction above described, among which the following may be named the can is provided witha combination screw and nozzlel which not only permits a screw cap to be applied to the can, but also enables the nozzle to be closed by a plug. That is the screw is wholly external to the nozzle, leaving the interior of the latter smooth so that it can be tigh-tly closed by a plug. The construction which secures this result is very inexpensive, and thus enables the can to be provided with either a plug or a screw cap, or both, without increasing the cost ofA production of the can to any material extent.

respect to the nozzle above described is novel with me, and makes it practical to employ a pouring lip in connection with a fixed nozzle can. When the can is closed or spout j having a threaded neck portion I prefer to term the latter the screw for the Several advantages arlse from thecon- The arrangement of the pouring lip with` the lip is turned down out of the way and the cap may be then put in place. It willbe noted that the cap when in place is held wholly by the screw and not by the lip. As the screw is ixed upon the nozzle, which itself istixe'd to the can, the cap can be vplaced upon or removed from the nozzle Without moving the lip, and it is not necessary therefore to hold the lipstationary while putting on or taking oft the cap. The cap also may be made tight onl the nozzle without necessitating the makingy of a tight joint between the lip and the can, or between the cap and the lip. In fact the lip vmay be loosely applied upon the nozzle, and

as it has no other connection with the can than through the nozzle, can be made and applied with very little expense..

1. The combination with a can having an externally threaded nozzle, of a pouring lip having a threaded neck rotatably engaged with the nozzle, being thereby capable of rotating until flush with the end of the nozzle,

and coperating abutments on the nozzle and lip for locking the latter when thus Hush with the nozzle.

'2. In a can, a nozzle having an externally threaded sleeve extending. less than the distance between the end of the nozzle and the canv body and having a shoulder Qn the end next to the body, and a lip surrounding t-he nozzle, having -a threaded neck rotatively engaging said sleeve and a flange underlying said shoulder, arrangedto be arrested thereby `when turned into pouring position.

ing from the outer end of the nozzle to a point between such end and the can bddy, and a pouring lip surrounding the nozzle having a threaded' neck engaged with the threads of the sleeve and adjustable thereon,

and a flange underlying the end of the sleeve, such neck being of substantially the same length as the sleeve. v

In testimony whereof I have aixed my signature, in presence of two witnesses.
