My invention relates to filling and venting devices and particularly to devices of the kind described that are adapted to be mountedl inbarrels, metallic drums, or the equiv? alent. v

The invention has among its other objects, the production of devices of thelrind described that are compact, convenient, durable, eiiicient and satisfactory for use wherever found applicable.

An object of theinvention is to provide an improved closure member for the lling opening of a barrel or the equivalent, which closure memberis adapted to permit removal of aV portion thereof for-filling the barrel, the portion remaining being constructed to serve as a lire bafHe suited to withstand usage incidental to inserting `a tube Vor thelike in the baille for filling.

Still'anotherobject is the provision' of an improved venting device adapted toH be mounted upon a barrel orv the'A equivalent, which' is capable of functioning as a venting device regardless ofv where it v.is located in the barreLand also regardless ofthe position of the barrel. g

lA particular objectfof the invention fis to provide ank improved lling and venting de-V vice which maybe mounted upon a barrel, or the equivalent, in such manner that it will not interferewith the handling thereof'.

Another particular object of the invention is to provide anrimpro'ved ventingdevice adapted to be mounted upon a barrel, or the Y equivalent, and constructed so that it may be readily adjusted to admit air 4into the barrel when the barrel is being emptied.

` Still another particular object of the invention is toprovide an improved ,closure memberl fort-he filling lopening of a barrel, or the equivalent, which closure member is adapted to permit the escape of gases from the barrel when the pressure ther/einy rises to a predetermined value, Y Many other ,objects and advantages of the construction herein shown and described'will be obviousV to those skilled in the artffrom the'dis'closure herein given; rIlo this endA my invention vvconsistsin` the 50 novel construction, Aai'ra"ngement and'c'ombination of parts herein shown and described,

andV more claim.

In the drawings, wherein like reference characters indicate like or corresponding parts: v f

Fig. 1 is a perspective view of a metallic barrel or drum upon which a device embody# ing my invention has been installed;

Fig. 2 is an enlarged section vtaken on line 2 2 of Fig. 1;

particularly pointed out in the Fig. 3 is a section taken online 8-*3 of Fig.

2; andl f o Fig. 4E is a' section taken on line 1- 4 of Fig. 2; v 'Y While my improveddevice isfshown and described in connectionV with 'a metallic bar-VV rel or drum, itis to be understood Athat my invention is'limited to this use only tothe extent indicated inthe appended claim. Referring to Fig'l, the reference character l0 designatesgenerally Ya filling and venting device which embodies aV preferred form of the invention and is installed upon'a metallic barrel orv drum whichV isdesig'n'ated bythe referencefcharacter 11. `The drum 11 is -of well'known construction and is substantially cylindrical in form. In linewith thev construction generally jemployed in -connection with drums or barrels of this type, the drumY 11 is provided with a plurality of annular beads 12 upon which the drinn may be rolled.` In this instance,l the iillin'gopening of the barrel` 0r drum 11 is disposed intermediate the beads 12 but it willbe `noted' that theimf provedlling andV venting devi-ce 10 may be mounted in the illingopening of the drum no matter where theiilling opening is located upon the drum. However, "my improved filling and venting device is particularly advantageous when itis mounted in thecylindrical WallVV of a drumlorlbarrel ofthe type shown in Fig. 1. n Referringto Fig. 42, the 'cylindrical'wall of the drum or barrel 11 is designated by the reference character 15 kand thel filling 'opening thereinis designated by thereference character 16. Mounted in the iillingopening 16 and rigidly secured to the wallfl is a collar 18. Screw-threadedinto the collar18 and projecting into the barrel 11 isv an annular member 19, the annular member 19 being provided with external screw-threads adapted to engage internal screw-threads formed upon the collar. The annular member 19 is also provided with internal screw-threads adapted to engage external l'screw-threads provided upon a boss 21 which form part of a plug 22, the plug 22 being adapted to be removed from the barrel whenever 'the barrel is to be filled. The annular member 19 is provided with a vdownwardly extending integral annular flange 23 provided with internal screw-threads which lare engaged bymenternal v screw-threads provided up'ona metallic ring' 2 4 to which a foraininous tube 25 is secured. The foraminous tube'2`5 is preferably pro-` vided with flame-proof apertures throughout its entire length and its lower end is preferably closed by a plate 27 which is' also preferably provided with flame-proof apertures. Resting upon the plate 27 is the bottomend of a tubular member 29, which is provided with a plurality of apertures 30,. rllhe apertures Jare preferably formed in the lower end of the tube 29 and are preferably larger than the iameproof -aperturesprovided in the tube 25. The lower end of the tube 29 is preferably closed Yby an apertured plate 32. The tube 29 and the plate 32 are preferably formed from thicker Ysheet metal than the tube 25 and its bottom plate 27 so that the tube29 and the plate 32 protectthe tube 25 and its plate 27 when sticks, filling nozzles, or the like, are inserted in the barrel through the filling opening thereof.y YAnother advantage of this construction is that the tube 29 protects the tube 25 in the event that an explosion occurs Within the tube 29. Thus, assuming that 'an explosion occurs vin thetube 29, it is readily understood that the lgases resulting from the `explosion will pass Ithrough the apertures -30 but the pressure thereof will be reduced to such an extentthat the tube v25 will not be subjected to the .full force of the explosion. The upper end of the tube .29 is preferably iared as Vat and preferably engages an annular :groove 36 formed in the bottom surface of the -annular member 19. Y

It will be noted that the tubular member `29 is disposed concentrically with respect to the tubular 'member 25 andthat :its wall is spaced from the tubular member 25 to provide an annular passage v38 which extends from the l bottom .of the -tubes up to the upper ends thereof. The upper end of the annular passage 38 communicates with the lower ends of a Yplurality of vertically extending apertures or passages 40 formed in the annular member 19.. Resting upon the upper sur-face of the annular member 19 :and interposed -between that memberand the -pl-uO 22 is agasket 42 which is preferably made of? some suitable material suchv as leather,'-or the equivale-nt. Obviously, if the plug 22 and thegasket'42 are removed from the barrel, and funnel or nozzle is inserted in the opening for filling the tank, gases may flow from the annular passage 38 up through the passages or apertures 40 and thence into the atmosphere.

Slidably journaled in the plug 22 is a vertically disposed pin or valve stem 44 which, at its upper end, carries a disk or valve 45. Also carried by the pin or valve stem 44 is an apertured gasket 47 formed from leather, or the equivalent, the gasket being adapted to seat upon an annular shoulder 48 formed in the bottom of a recess 46 provided in the plug 22. A compression spring 50 disposed around the pin or valve stem 44 and interposed between the plug Y22 and cast-le nut 51 carried by the valve stem yieldingly holds the gasket 47 in engagement with the seat or shoulder 48. Formed in the plug 22 Within the boundaries of the annular seat or shoulf der 48 are Aa plurality of ports or vents 54 through which gas may escape from the barrel when the gasket 47 is disengaged from the shoulder 48. Obviously, the spring 50 may be adjusted to permit the escape of gas from the barrel when a predetermined pressure obtains therein.

It will Ybe noted that the recess 46 is of sutlicient depth so that the upper surface of the valve 45 normally lies beneath the upper surface of the plug 22 and that the gasket 47 may be disengaged from the .shoulder 48 without bringing the upper surface of the valve 45 above the upper surface ofthe plug.

This is advantageous in that when the barrel is in a position wherein the plug contacts or substantially contacts the surface upon which the barrel is supported, the valve 45 may be displaced tojallow -a reduction in the pressure within the barrel. The plug 22 preferably projects a relatively small distance from the barrel so that it will not be injured when the barrel is rolled along 'upon its beads 12. n

When the barrel is to be filled with liquid, the plug 22 and the gasket 4 7 are preferably removed from the annular member 1-9 so that the liquid may be poured into the barrel or a nozzle maybe inserted in the tube 29 to discharge the liquid therein. The air displaced in the barrel then passes through the 4annular passage v38 and thence through the apertures 40. When the contents of the bar-rel are to be removed therefrom, the plug 10b is removed .from the screwthreaded opening 10a and a faucet (not shown) lis inserted therein. The plug 22 is unscrewed a few turns so that the gasket 42 does not seal the upper ends .of the apertures 40. Obviously, when the faucet is opened to permit the liquid to escape from the barrel, air may' enter through the apertures 40 so that lthe contents of the barrel can Vbe quickly discharged through the faucet. Y

Having thus Vdescribed my invention, it is obvious that various immaterial modifications may be made Vin the same without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or usesmentioned.

What I claim as new and desire to secure by Letters Patent is:

In a device of the class described, a pair of foraminous tubular members closed at one end and telescoping each other with a space therebetween, means engaging the open ends of said tubular members and adapted to close a tank or the like, said means having a flange forming a recess, said means also having a perforation therein, and a valve vseated in said recess, said valve having a face yieldingly seated over said perforation and adapted to be unseated upon the exertion of a predetermined pressure on said face, the depth of said recess being greater than the maximum movement of said valve.

In testimony whereof, I have hereunto signed my name.

RUDOLPH J. ANSCHICKS. l
