RECEPTACLE.

Application filed. October 8, 1915.

To all whom it may concern:

Be it known that I, lVILLIAn r H. MoNUT'r, a citizen of the United States of America, residing at New 'York city, in the county and State of New York, have invented cer tain new and useful Improvements in Receptacles, of which the following is a specification.

My invention relates generally to receptacles especially designed to contain inflammable or explosive, liquids, and is concerned particularly with a closure for receptacles of this kind.

The general type of can to which I contemplate applying my invention is that disclosed in United States Letters Patent No. 1,114,165 issued to me October 20, 1914, and my present improvements relate to certain structural features to be hereinafter fully explained.

The principal object of the present in vention is to construct the can closure in such a manner as'to completely prevent leakage of liquid or escape of vapors from the interior of the can. I accomplish this purpose by a unique construction of the nozzle and cap or cover, whereby these two parts will be complemental to each other in providing the desired tight closure.

Another object of the invention is to simplify the construction of the closure so that the packing gasket, which is provided in the cap to seat against the upper edge of the nozzle, may be readily removed and replaced.

A further object of the invention is to provide a novel form of guard for the spring which seats the can closure over the nozzle mouth when the can is not in use.

Other objects of the invention, and its detail structure and operation, will be fully described in the following specification, reference being had to the accompanying drawing, in which Figure 1 is a perspective view, partly in section, of a can embodying my improve ments;

Fig. 2 is an enlarged vertical sectional view of the nozzle and appurtenant parts of thecan; and i Fig. 3 is a perspective view of a spring guard which I may employ.

The present invention is concerned with a type of can having a closure or cap which is normally drawn to its seat by a spring r quiva n t e h are. req i t he Specification of Letters Patent.

manually unseated when any of the contents are to be poured from the can. In this way the can is kept in closed condition when not in use so that evaporation and explosion and ignition are avoided.

Referring to the accompanying drawing by reference characters, 10 denotes the can body which may be of any desired form, although the form which I find to be best adapted to the purpose is substantially cylindrioal. The upper part of the can is formed with a breast 11 which may be somewhat tapered or conical in form, and has suitably secured thereto, as by spot welding or otherwise, the nozzle 12 which is of cylindrical formation.

Secured to the nozzle 12, and depending well within the can body 10, is a mesh tube 13, the function of which is to prevent ignition or explosion of the can contents, in a manner well-known in this art.

The upper edge 14, of the nozzle 12 is beaded or upset, and presents a surface with which the cap cooperates to provide a tight closure of the can in a manner to be described.

The form of closure which I prefer comprises a substantially circular cap 15 having the depending annular flange 16, the latter being designed to embrace the beaded portion 14 of the nozzle 12. Contained within the cap 15 is a gasket 17 of any suitable substance such as leather, asbestos, raw hide, or the like, the latter being preferable. The gasket 17 is designed to seat tightly against the upper face of the head 14. Engaging the gasket 17 is a preferably frusto-conical guide 18 which serves to guide the cap 15 into proper position when the same is released by the user of the can. This guide cooperates with the curved inner edge or surface of the head 14 in causing the cap 15 and gasket 17 to properly seat over the mouth of the nozzle 12.

I prefer to form the cover 15 with a central boss 19 which is telescopically engaged by a supplemental cap 20 having upstanding lugs 21 to receive the lower inturned ends of an operating bail 22.

The entire cap structure including the cap proper 15, the gasket 17, the cone 18, and the supplemenal cap 20, is held together by means of the eyelet 23 the upper end of which is threaded and receives the nut 24 which is adapted to be screwed down. against cap 20.

As heretofore seated, the means for normally forcing the cap 15 to its seat preferably consists of a coiled compression spring, which is engaged by a guard, forming one of the features of my invention which I will now describe.

/ In Fig. 3 of the drawing, I have illustrated the novel form of guard which serves the treble purpose of connecting the cap structure with the lower end of the mesh tube 13 through the intermediary of a coiled compression spring; preventing the spring itself from being subjected to excessive strains; and also preventing the cap from being pulled out of the can;

The guard comprises the substantially parallel shank members 29 and 29 the intermediate loop member 29 and the lower hooked member 29 Engaging the eye 25 of the eyelet 23 is an eye 26 'of a link 26, the opposite end of which has a loop or eye 26 engaging the upper hooked end of the coiled compression spring 27. The lower end of the compres sion spring is also hooked and engages the intermediate loop 29 of the guard. It will be noted that the shank 29 of the guard passes through the eye 26 of the link 26 and that the opposite shank 29 is downwardly bent so that the strand between the two shanks forms a stop for the upward pull of the spring.

.As appears clearly from Fig. 1, the hook 29 of the guard engages a stirrup 30 which is held in the lower end of the mesh tube 13, whereby the cap 15 is yieldingly connected to the mesh tube.

Pivotally supported by lugs 31 on the breast of the can is the carrying bail 32 which may be of any approved construction.

The operation of my invention is as fol- V lows :When it is desired to empty all or a portion of the can contents, the operator grasps the carrying bail 32 and passes one or two fingers through the operating bail 22, this'being done while the can is upright. To discharge the contents from the can, the lat ter is tilted into a horizontal position, as a result of which the cap 15 is unseated, allowing a free flow from the mouth of the nozzle 12. This unseating of the cap and its appurtenant parts takes place against the tension of the spring 27. When sufficient of the contents have been emptied or discharged, the operator simply releases the bail 22, whereby the spring 27 will contract and draw the cap 15 to its seat 14. In this action the cone 18 will cooperate with the curved inner surface of the beading 14; to properly center the cap 15 relatively to the nozzle 12 and cause the flange 16 to truly engage the outer periphery of the bead 14.

One of my aims has been to provide simplicity in the construction of the closure, and it will be observed that I have accomplished this by making the assembling and disassembling of the several parts of the cap practically dependent upon the nut 24 and the eyelet 23. If it be desired, for example, to disassemble the parts of the cap closure, it is merely necessary to loosen the nut 21 whereby the eyelet 23 may be withdrawn from the cap, and the several parts of the latter, including the cone guide 18, are free to be separated. This is of importance particularly when it is necessary or desirable to replace the gasket 17, which is subject to considerable wear. The spring 27 may be replaced with equal facility, by disengaging the link 26 from the eye 25, freeing the two ends of the spring 27 from the eyes in which they engage and thereafter, when a new spring has been inserted, again hooking the link 26 into the eye 25.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is .1. A device of the character specified, comprising a receptacle having a projecting nozzle, a cap adapted to seat over said nozzle,
