BARREL-CLOSURE.

Specification of Letters Patent.

Patented May Q 1911 Application filed April 5, 1909. Serial Ilo. 3853923.

To all whom "it may concern:

Be it known that I, AUGUSTA M. Screen, a citizen of the United States, residing at Buli'alo, in the county of Erie and State of New York, have invented a new and useful Improvement in Barrel-Closures, of which the following is a )ecificatio'n. I

This invention re ates to a barrel closure and has the object to provide a closure of this character whereby the barrel may be securely and reliably closed, which can be easily and conveniently manipulated and which can be produced at comparatively low cost. 7

In the accompanying drawings Figure l is a longitudinal section of my improved barrel closure showing the parts assembled preparatory to tightening the closure. Fig.

2 is a similar View but sh wing the holding device in elevation and the closure tightened. Fig. 3 is an end view of the outer section of the bung. is a cross section in line 44. Fig. 2. Fig. 5 is a fragmentary longitudinal section showing the manner of interlocking the holding device and the outer bung section.

Similar letters of reference indicate corresponding parts throughout the several news.

A represents a barrel or similar vessel or article having an opening in which is secured a circular bushing B having an external screw thread 7) and an inwardly or for wardly tapering bore. Within this bushing is arranged a hung having inner and outer sections C, C which are movable axially relatively to each other and which are adapt: ed between them to expand a packing ring D within the bushing.

The relative axial movement of the bung sections is preferably ellccted by means of a screw joint between them so that upon turning the sections one with reference to 'the other the ections will approach onrecede from each other. This screw connection, as shown in the drawings, consists of an internally threaded annular flange 0 on the outer end of the inner hung section rec-1' iug an externally threaded annular ti: on the inner end of the outer bung section.

The inner bung section is smaller in diam: etcr than the inner end of the tapered bore of the bushing and provided externally with an annular forwz rdly facing and beveled tapered shoulder 0 while the outer bung tion is of larger diameter than the inner. end of the bore of the bushing, so thatupon inserting the hun in the bushin the inner bung section will pass inwardly yond the inner end of the bushing but the outer bung section will engage the bore ofthe same, as shown in. Fig. 1. The packing ring D which consists of rubber or similar material sur rounds the inner bung section and is en aged at its inner edge bv the beveled shou der e of the same while its outer ed e is engaged by an opposing abrupt shoulder e on the outer bung section.

While introducing the bung into the bushing the sections of the same and the packing contracted. After these parts have been inserted in the bushing until the outer section engages the bore of the bushing and the inner section is arranged beyond the inner end of the bushing, as shown in Fig. 1, the inner section is turned, so that the screw connection between the same and the outer section causes the same to move outwardly. thereby expanding the packing at the inner edge of the bushing and tightly closing the barrel, as shown in Fig. 2-. For opening the closure of the bar," rel the operation of the bung sections and packing gust described is reversed, so as to separate the bung sections and permit the packing to contact.

The separation of the bung sections is limited by means of two parallel lugs l1, F projecting outwardly from the cntral part of the inner bung section. and eac 1 provided with a laterally projecting lip f forming an imvardly facing shoulder which is ada )ittl to engage with an outwardly facing shou dcr formed on an internal annular flange y within the bore of the outer hung section. The hung sections are coupled in this mannor by inserting the lugs F, F outwardly through the central opening'in the outer bushing section and then breaching, upsetting or swuging the ends of these lugs outwardly, soas to form the laterally project-' ing lips f thereon which overlap the flange 0. The opposinginuer sidcs ot the lugs l l of t e inner bushing section are preteruoly tlat sidednnd parallel, forming a socket which is adapted to receive the flat sided inner end 71. or a key rod H which passes through a central opening ii in the outer hung section and whereby the inner bung section may be turned when tighteuin5 orare separated turned, the outer bung section @t the coupling dill loosening the closure. This key rod is provided at its outer end with a finger piece h for operating the same.

While the inner bung section is being is held against turning by a holding device which constructed as follows :--1 indicates a hollow cylindrical holder body surrounding the key rod and provided on opposite sides'of its inner end with T-shaped coupling or locking heads 2' which are adapted to enter corresponding undercut sockets or recesses J-fornied on the outer end of theout'e'r bung section on opposite sides-of its center. At its outer end the holder body is provided with a knurled finger piece K which contains an opening Z through which the key rod passes and an inwardly facing shoulder m in its bore which cooperates with an outwardly facing shoulder m on the periphery of the key rod for limiting the retracting ncovement of the rod in the holder.

In ap lying the bung to the bushing the same is rst coupled with the holder and key by engaging the inner end of the key with the socket of the inner bung section and enaging the hooks on one side of the heads of the holder With the corresponding sides of the undercut sockets t the outer section. "When the parts are thus coupled, the hey is turned in a direction opposite to the interlocked sides of the holder beads, whereby the outer bung section is held against turning and the inner section is turneo. in the d'rection for causing it to preach the outer section, thereby expanding the packing in the bushing and closing the barrel. F or opening the barrel the holder is turned in a reverse direction until the hoolts on the opposite sides of the coupling heads engage under the opposit" undercut parts of the sockets in the outer bung tion then the key is turned in ti After the bong has vets direction. loosened the same is withdrawn from the bushing. lily thus coupling the bushing with the holder While introducing the same into the bushing and removing the same therefrom, the saline in the absence of any provision to prevent it, would be liable to drop ed the holder, inasmuch asthe hooks heads are of less thickness the sockets in the outer than the depth oil? a yielding lonng section. To prevent this, tension or pressure draws the hooks outwardly against the un: dercut parts of the sockets therein and thus bu 11g a hollow body device is provided which i holds these parts 'trictionully in place relatively to each other. The preferred means "for thus frietionully coupling the holder and outer bung section consists of a hearing or pressure sleeve ix movable lengthwise in the inner part. of the pocket in the hollow body of the holder and provided with a central opening it through which the key rod passes and a spring osurrounding the key rod and hearing at its opposite ends against the outer end t said pressure sleeve and the outer end of said pocket, the inward or for- Ward movement of the hearing or pressure sleeve being limited by an inwardly facing shoulder 72 formed on the bearing sleeve and adapted to bear against an outwardly facing shoulder 7) in the bore of said holder pocket. By this means the bung may be readily attached to and removed from the holder and freely manipulated Without liability of dropping oil, thus facilitating the Work of applying the bungs and removing the same from the bushings.

I claim as my invention:

A barrel closure comprising a bushing adapted to be secured in an opening in a barrel, a hung arranged in said bushing and having inner and outer screw-connected scotions provided with opposing external shoulders, an elastic packing ring arranged between said shoulders and adapted to be expanded within said bushing, said inner bushing section'having a flat sided socket and said outer bushing section having an undercut socket, a handle for holding the outer lu'ashing section against, turning havand a T-shaped head adapted to engage with said undercut socket of the outer bushing. section, a key for turning said inner bushing section having a rod arranged centrally within said. holding handle and having a iiat sided inner end ch is adapted to engage with the flat sided socket oi"? the inner bushing section and a yieltfling pressure device for holding the ilOlCllllf handle in place comprising a sleeve movablelengthwise within the holding handle and adapted to engage with the outer side of the outer bushing section, and a spring arranged within the holding handle and pressing said sleeve inwardly.
