BUNGFASTENER.

SPECIFICATION forming part of Letters Patent No. 381,920, dated May l, 1888. VApplication tiled August 16, 1887. Serial No. 247,049. (No model.)

To all whom it may concern.-

Be it known that we, GEORGE ALEXANDER GEMNDEN and ALBERT F. GETNER, of Savannah, in the county of Chatham and State of Georgia, have invented certain new and useful Improvements in Closing Devices and Fasteniugs for Barrels orother Packages, ofwhich the following is a specication, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention is designed to prevent the 'forcing out of the bung by the pressure of the liquid heldin the package or the gases contained in said liquid, and also to prevent leakage caused by the use of an imperfect bung or by the rough handling of the-package.

The invention is also designed to. render unnecessary the use of a pressed or costly-1inished bung and the consequent hard driving of the bung into the bushing or package itself, thus facilitating a proper sealing and closing of the package without injury thereto.

In the accompanying drawings, Figure 1 is a vertical section of the ring. Fig. 2is a similar section showing the ring, bung, and fastening devices in one form of our invention. Fig. 3 is a plan view showing parts, as hereinafter explained. Figs. 4, 5, 6, 7, 8, 9 and 10 illustrate details, hereinafter explained. Fig. 11 shows a vertical section of a modication of our invention. Figs. 12 and 13 represent in detail parts of Fig. 11. Figs. 14 and 15 show vertical sections of modifications of our invention, as hereinafter described.

Similar letters of reference indicate similar parts in the respective figures.

A is the barrel or package.

B is the ring for attachment to the package, and C the bung. The ring B may be threaded or burred upon its exterior, as shown in Figs. 1, 2,' and 11, and adapted to be screwed or driven into the package, so as to be effectually held therein by such means alone, or it may be additionally secured by screws,as seen in Fig. 14, or simply screwed to the package, as shown in Fig. 15. The ringB is provided with a top flange, a, and a groove, a', the diameter of which is the greater at its base or bottom.

It being desired to close the package, the bung C is rst driven into the ring B, as shown in Fig. 2, whereupon the parts are in readiness to receive the fastening appliances. These consist of the following devices: A disk or washer, b, made of soft metal, rubber, leather, or any `suitable flexible material, is passed through the top of the ring B and pressed into the groove a. The disk b will effectually prevent leakage arising from the use of animperfectly constructed or imperfectly fitting bung. Upon the disk b is now placed an iniiexible metal plate or disk,c, as shown in Figs. 4, 5 and 6. The disk c is preferably shaped or beveled at its edges, as differently shown in cross-section in Figs. 5 and 6, the beveled or specially-shaped parts being intended for a purposer hereinafter explained. The entire periphery of the disk c may, however, be beveled or shaped as shown in Fig. 4 or 5. The disk c is adapted to press upon the disk b and thus spread it out upon the bung andinto the groove a. The disk o having been put in placethe guard d is applied. The guard may consist of a single bar of metal, as shown in plan in Fig. 3 and by full and dotted lines in Fig.2,or of a three-armed device, illustrated in Figs.7 and 8, or a four-armed device. (Seenin Figs. 9 and l0.)

In Fig. 1 the groove a is provided with notches a2, to receive the ends of the single bar or guard d. In all cases the guard d is made of any pliable metal of sufficient strength and rigidityfor the purpose in View. The guard d, lirst having the convex form seen in Figs. 2, 8, and 10, is entered in the top of the ring, as shown in dotted lines in Fig. 2, and then flattened out, so as to be forcedinto the groove a', as shown in full lines in the same gure. The arms of the guard fit over the beveled portions of the periphery of the disk d, said beveled parts being equal to the number of the arms and adapted thereto. The bung is thus tightly sealed and secured in the package.

Figs. 11, 12, and 13 show modifications of the invention as used for packages having small openings. Here the metal disk c is omitted, and instead of the skeleton guard d, (shown in Figs. 7, 8, 9, and 10,) or the simple guard d, (shown in Figs. 1 and 2,) a solid guard d is used, it being shown applied in Fig. 11 and detached iu Figs. 12 and 13.

Figs. 14 and 15 show further modilications,

lOO

in which the bung is not driven tightly into disks Z and @,and guard d, adapted to be driven the ring, but directly into the package. into the groove, so as to rest upon the disk c,

The advantages of this invention are obvisubstantially as Set forth. ons; and it is also evident that the various l In testimony whereof We have hereunto set I5 5 parts are capable of minor changes in construcour hands and seals.
