BUNG.

SPECIFICATION forming part of Letters Patent No. 525,833, dated September 11, 1894.

Application tiled November 21I 1893. Serial No. 491,539. (No model.)

To all whom t may concern:

Be it known that I, JOHN BAEUMLE, of Milwaukee, in the county of Milwaukee and State of Wlsconsin, have inventeda new and useful Improvement in Bunge, of which the'followlng 1s a description, reference being had to the accompanying drawings, which are a part of this specification. f

My invention has relation to improvements 1n bungs.

rIhe invention consists of the devices and parts as hereinafter described and claimed, or their equivalents, constituting more espeelally certain improvements upon the Letters Patent of the United States issued to me under date of September 20, 1892, and numbered 482,714.

In the accompanying drawings, Figure 1, represents a fragment of a stave in which my improved bung is inserted. Fig. 2, is a trans- Verse section on the line 2-2 of Fig. 1. Fig. 3, 1s a view of the inner face of the frustoconical collar, and Fig. 4, is an elevation of the expansible ring.

Like numerals of reference denote like parts throughoutthe several views. Referring to the drawings, the numeral 1 1nd1cates a stave of a barrel in which an ordlnary bushing 2 is inserted in the screwthreaded bung aperture thereof.

The numeral 3 indicates a disk, forming part of my improved bung, provided with a central screw-threaded aperture, and having its outer face of substantially truncated conical form, and its inner face provided with a central inward projecting screw threaded b'oss 4, which is adapted to receive. an interlorly threaded cap 5. The edge of the disk 1s formed with an outward-extending peripheral flange 6. Adapted to pass through the central screw-threaded opening of the disk is a bolt 7, said bolt being threaded between the

plane portions

8 and 9, as clearly shown lin the drawings. The bolt is further formed, next to the part 9, into av hexagonal enlargement 10, and nally terminates in the'usual headed portion 11.

Bearing against the disk 3, and surrounding thebolt, is a ring 12, of rubber or other Suitable elastic material, of a form substantially cylindrical upon its outer face, and its inner surface beveled from the ends inward, forming tapering

portions

13 and 14, the former registering with the disk 3. The periphery of this ring, at opposite edges, is recessed, as indicated at 15, 15, the inner recess receiving the peripheral iange 6 of the disk 3, and the outer recess receiving a similar iiange 16 formed annularly around the periphery or rim of a frusto-conical collar 17, whereby said anges are brought flush with the main portion of the ring. The truncated apex of this collarv is provided with a central aperture through which the bolt 7 passes, the plane portion 9 of said bolt, when in the position illustrated in Fig. 2, registering therewith.

The outer face of disk 3, and the inner face of collar 17 are provided with a series of

radial ribs

18 and 19, respectively, which are adapted to take into corresponding grooves 2O formed in the respective contiguous surfaces of the ring 12, when the parts are adjusted t0- gether, and thereby hold the disk and collar rigid with the rubber ring. A transverse pin 21 intersects the plane portion 8 of the bolt, and is'adapted to act against the inner face of the disk 3, as will hereinafter more fully appear. It will be noticed that the cap 5 protects the central opening of the disk 3, and prevents the entrance of any pitch, or the contents of the barrel, into the bolt opening, by reason of which said opening is always kept free of extraneous matter, and therefore prevented from being clogged. The

flanges

6 and 16 of the disk and collar, respectively, also prevent the entrance of any pitch, or other matter, between the contacting faces of the disk and collar and the ring, which matter would otherwise enter said space and prevent a nice adjustment of the parts together, and also ll up the grooves 20, and thereby prevent the

ribs

18 and 19 from interlocking therewith. The lianges also have a further important function in preventing the outer edges of the ring 12 pressing or spreading out against the metallic bushing, and they also assist in holding the disk and collar more firmly to the rubber ring, so that the turning of said ring past the radial ribs is rendered more difcult.

IOO

Prior to applying my improved bung, it will be understood that the inner disk 3 is not screwed up against the face of the rubber ring close enough to expand the latter. In view of this, no trouble is experienced in inserting the bung in place. After adjustment, however, the bolt is turned, preferably by means of a tool or Spanner engaging the hexagonal enlargement. As the bolt is thus turned, the disk 3 is forced outward against the face of the rubber ring. When the bolt has been screwed inward far enough to allow the hexagonal enlargement to bear against the collar, the latter also is made to exert a pressure against the rubber ring. The result of these two pressures against opposite faces of the ring is of course to spread said ring outward against the bushing, thus making a perfect liquid and air tight closure of the bung hole.

When it is desired to remove the bung, the bolt is turned in the opposite direction to that before described, whereby pressure against the rubber ring is relieved. After this, the bung may be readily pulled out by applying lateral force thereto. It sometimes happens that the bore of the bushing becomes coated with pitch, resulting in the rubber ring 12 adhering closely thereto. In such case, it is quite difficult to remove the bungs by a direct pull thereon, without first turning the rubber rlng, and loosening the same. To provide for the removal of the bung under such circumstances,l employ the transverse intersecting pin 21, so that after the bolt has been screwed outward a certain distance this pin will come in frictional contact with the end i of the boss 4. Before such engagement the bolt of course turns independently of the other parts-that is to say turns in the aperture of the disk without imparting a corresponding rotation thereto. The moment the pin makes contact with the end of the boss, however, the disk is made to rotate, and as the rubber ring is locked thereto by the engagement of the ribs upon the outer face of the disk with the corresponding grooves of the ring, said ring is also rotated, and in addition thereto the frusto-conical collar. Of course, thc moment the ring is rotated, if any pitch upon the bushing has caused an adherence between the latter and the ring, said ring is loosened in this way, and the bung removed without difficulty.

In addition to the above means for 1cosening the rubber ring from the bushing in case the latter adheres to said bushing by reason of an interposed coating of pitch, I provide in the present improvement other means for obtaining the same result, which means may be either used in connection with the other mechanism above described, and which is covered in my former patent hereinbefore re ferred to, or may be used entirely separate therefrom. This means consists in forming in the rubber ring l2 an annular groove 22, which receives therein an expansible split ring 23. As the rubber ring is expanded by drawing together of the disk and collar throughtheaction of the bolt the split ring is also necessarily expanded. Now, without the employment of the expansible split ring, in case the rubber ring should stick to the bushing through the cause abovementioned, after the disk and collar are made to recede from each other, for the purpose of withdrawing the bung, it will perhaps be found that the rubber ring does not possess sufficient contractile power to release itself from the pitch. By the provision of the expansible ring, however, this ring will by its own inherent contractile power resume its normal condition, after the pressure of the disk and collar is discontinued, and in resuming this normal state will necessarily carry with it and contract the rubber ring, and thus release the latter from the adhering pitch.

The present invention differs from that described and claimed in my former patent, No. 482,714, dated September 20, 1892, not only in the provision of the feature just described, but also in providing the peripheral anges for the disk and collar, and the protecting cap secured to the projecting boss of the disk.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a bung, the combination, of an elastic ring, provided with a peripheral groove, a split spring ring fitting in the groove of the recess, and means for expanding the elastic ring against the bushing of the bung-hole,
