BUNG FOR CONTAINERS Filed Dec. 8, 1930 INVENTORS Mei ATTORNEY 'Patente d Sept- 20, 2. V I
UNITED .s TATEs JosEPnmmME srAonEE Ann ERNST HEPTING, LOF NEWARK; NEW JERSEY- IB'UNG, EOE CONTAINERS I Application filed December s, 1930. S eria1 1lTo.f500,713I I 2 This invention relates to bungs for containers, andmore particula-rlytov abung for oil drums, barrels and other receptacles used in the shipment or transportation of como 5 modities. I
r The art has heretofore experienced con siderable difficulty in preventing the closure bung from working loose under severe shocks and jars, to which such containers or recep- Q tacles are subjected by the rough handling thereof in loading the same upon or removing them from the transporting vehicle. It is theprimary object and purposeof my present invention to provide a simple, effective and comparatively inexpensive means for tightly sealing the bung opening and securely locking the bung against turning movement from its applied position except bythe appli-' cation of a proper wrench and the use of considerable manual force.
More particularly, it is one of the important objects of my invention to provide a. bung adapted for use in connection. with the conventional internally threaded spud or "constructed and associated with parts of the i bung structure that said means will also exert a lateral expansive pressure against the bung 1 and the'threads of the spud or r1ng, thereby producing a supplementarylocking effect upon the bung and also thoroughly sealing the bung opening against every possibility of Z the escape of the contents of the container '4 therethrough.
With the above and other objects in; view, the invention consists in the improved bung forcontainers or receptacles and in the form, construction, and relative arrangementof its A 7 several parts as will be hereinafter more fully sealing and locking washer, the latter being ring'which is fixed to the receptacleWall the bung to tightly jam the threads thereof described, illustrated in the accompanying drawing, and subsequently incorporated in the subjoined claims.
In the drawing, wherein we havedisclosed 'onefsimpleand practical embodimentof the 55 I Y device, and in which similar reference characters deslgnate corresponding parts throughoutthe several views,.
' Figure l isa plan view showing one form of the device asapplied to the'containerwall {60 i Fig. 2 ls an enlarged sectional view taken .on the line 22 offFig. 1, and T a Fig; 3 is a detail View of the bung-and the shown in section.
i Referring in detail'tothe drawing, 5 desig 'nates a portion of one of the walls of a metal drum, barrel or other receptacle which isprovidedwithfthe opening indi'catedat 6 therethrough. 3 1
1 A ring or spud? of any conventional form is welded or otherwise rigidly and permanently fixed to the container wall 5 around the opening 6. As herein shown,this spud -1s-'provided with an outwardly extending '7 flange 8 internally threaded as at 9, an out- 1 wardly projecting annular-shoulder 10 being formed at the inner end of the threads 9-jfor a purpose which willpresently appear.
Theotherend of the bung 11 is formed with a concentric axially projecting reduced portion 15 which is unthreaded buthas cen- .trally' formed therein'a threaded bore 1 5 Upon. this unthreaded inner end of the bung,
an annular locking and sealing washer 16 is adapted to beengaged. J This washer is. constructed of a compressible material, pref i erably cork, and in its initial form has a thick- 5.9 5v ness somewhat exceeding the length of the cylindrical projection l5 of the bung, The compressible-washer '16 is held in its applied position by means of the metal washer plate 17-engaged against the end face of the,p'ro- The bung or plugllis externally threaded 80 ,as at'12 and'provided on one end with a flange V 18 of-any' desiredpolygonal contour for; the application of a -.su itable wrench thereto. Preferably, this end of the bung is also centrally provided with the wrench? receiving socket indicated at 14. I a
7 ing of greater diameter than said projec jection of the bung, said washer plate betion, and therefore, overlapping upon the washer 16. It will however, be noted that the diameter of the metal washer plate issuch that its outer edge isspaced from the shoulder 1O of the spud or ring 7. .This washer plate is rigidly fixed in its applied position by means of the screw 18 engaged through a central opening in said plate and threaded into the bore "15". If'desired, an "adapter member 19 in the form ofa short internally threaded sleevemay also be secured byfthe screw 18 to said bung,- t-heclos'ed end of the faucet to the bung whichwill therefore project: into the drum or container and be protected against injury. The consignee of a shipment, by unthreading the bung from'the spud or ring 7, may readily rem'ove this faucet and connect the same with the threaded ring or spud of a second opening provided in the wall of the container 1 and through which the contents, offthe container maybe Withdrawn in measured quantities. 7 y
In addition to the sealing and locking washer'16, we also preferably ,provide an annular gasket 21which-is adapted to be interposed between the inner face of the flange 13 and the flange 8 of the spud or ring 7 .1 In the use of the device as above described, after the sealing ring 16 has'been assembled. on the reduced inner'end of the bung '11 and secured in place by the washer plate 1'? and screw 18, the gasket 21 is" inserted' -over the threaded part'of the bungagai nst the flange '13 The bung is then screwed or threaded in- "w'ardly into the threaded flange of thering or spud- 7'and after the sealing'ring 16 engages upon the shoulder10, upon further turning movement of the hung in the same direction, said ring 16 will becompressed. It
will of; course,-l oe understood that whenfthe "washer plate '17 was appliedand tightened against the end face of the extension 15 of the bung by means of the screw 18, the inner part of the washer 16 was; somewhat compressed,- owing to the fact that the thickness 7 (if-said washer slightly;exceeds the length of the extension-15'. Therefore, when the furthercompression of said washer occurs'under the inward threading movement of the bung,
it tends toflexert a hi hly expansive force or 1 pressure both-axially and laterally, the outer side" of 's'aidcompressible material of. the
washerinterlocking with the threads 9'of the ring or spud while said washer at'its'inn'er side is forced into very; tight frictional binding cont-act againstthe periphery ofthe extension 15 of the bung, For. the same--reason, said compressible sealing ring will exert an outward axial pressure against the bung at the inner end of the extension 15 thereof until it becomes no longer possible to thread the bung inwardly due to the jamming of the threads thereof with the threads of the ring flange 85 which produces such a high frictional locking action that reverse rotation of the bung or unthreading movement thereof from the flange 8 such as wouldbe incident to heavy shocks or jars; is also effectually prevented. At the same time, the outer annular gasket 21'isj placed undera heavy compressive forceg l lhus in this manner, it will be evident that the opening'through the spud or ring 7 is tightly sealed both at the inner and outer endsv of thebungwhilecat the same time the bung is securely'lockcd in itsapplied position and loosening thereof byt'outwardturning movement of the bung in the spud or ring 7swhich would destroy' the effective sealing action of the ring 16 and permitof the seepage of the contents of the container. outwardly through the bungopening or'the escape of air or gasestherethrough is obviated. In order to remove the bung, it is necessary to apply the proper wrench to the outer end of the same and exert a very heavy manual turning force in order to overcome the frictional binding actionbetween the threads. of the bung and the threads on the .ring or spud '7,
From the foregoing (18801111131011COnSlClIQd inconne'ction with the accompanying drawing,it will be *seenthat we have produced a very simply constructed, inexpensive and efficient sealing bung for containers or receptacles; 'lhe device is particularly advantageous for use in connection-with such metal drums,- casks or barrels as are. commonly emp'loyed for the shipment ofoilsand lubricants which are frequently subjected during transportation, to rough and abusive handling.
also be incorporated invarious other alter-' native structural forms, and we therefore,
legitimate changes therein as may be fairly embodied within-the spirit and scope of the appended claims;
*We'claimc :r f "1'. In combination: withan internally threaded spud provided atthe inner end of its threads with an inwardly projecting annular shoulder, an externally threaded bung, said bungqat its innerend havinga reduced axial extension, an annual sealing and locki'ng' washer' engaged upon said bung extension', sa1d washer being composed of a com reserve the privilege of resorting-toall such pressible material, a retaining plate engaged against the end face of thebung extension and overlapping upon the inner portion'of said washer, and an attaching screw for said 7 plate having threaded engagement in the:
bung extension, the outer part of the'compressible washer engaging the shoulder of the spud upon inward threading movement of against the bung to frictionally lock the threads thereof with the threads of the spud and thereby prevent casual reverse movement of the bung. 7 Y I 2. In combination with an internally threaded'spud provided at the inner end of its threads with a narrow inwardly projecting annular shoulder, a bung having an ex? ternally threaded portion to engage the threads of the spud andprovided with a re-' 7 v duced axial extension projecting from said threaded portion of materially less diameter than the internal diameter of said shoulder,
a an annular sealing and locking washer of com-V pressible material normally of greater thickness thanthe length'ofs'aid bung extensionv and closely surrounding the latter, and means 7 retaining said washer in assembled relation with the bung to be handled as an entity there I with, said means including a part engaging the inner portion of the washer and holding the same under compression, whereby upon the inward threading movement of thebung into the spud, the outerportion of said washer is engaged upon the shoulder of the spud and placed under compression to interlock'said' washer with the inner'threads of the; spud and exert an outward axial force against the v bung to frictionally lock the threads thereof with the threads of the spud.
In testimony that we claim the foregoing as V our inventlon, we have slgned our names hereto.
