GEORGE STIEFEL, OF CHICAGO, ILLINOIS.

BUNG-CLOSURE.

T0 all whom it may concern:

Be it known that I, GEORGE STIEFEL, a subject of the Emperor of Germany, and a resident of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Bring-Closures, of which the following is a specification.

The essential objectof this invention is to provide a bung-closure which, in certain respects, is an improvement upon and addition to the bung-closure which is shown and described in my pending application 'for patent filed August 8, 1911, Serial No. 643,002. The closure shown and described in the aforesaid application is particularly adapted for use in connection with the head of a barrel, whereas the bung-closure shown and described in this application is one which is primarily designed to be applied to a bung-hole which is bored through one of the staves of the barrel at or near the bilge.

In the drawings, Figure 1 is a top plan view looking toward the barrel, part o'E the outer casing being broken away; Fig. 2 is a View similar to Fig. 1, the movable parts being shown in dotted lines and in a different position from that depicted in Fig. 1; Fig. 3 is a sectional view taken on the line 3-3, Fig. 1; Figs. 4 and 5 are sectional views of the botttom cap, Figs. 4 and 5 being in inverted position as compared to Fig.`3; and Fig. 6 is a View of the bung-closure with the device :for operating the valve applied thereto, some of the parts being shown in section and some in elevation.

The casing 1 is cylindrical in shape and is provided with external screw threads 2 adapted to be screwed into the bung-hole of the barrel. The bottom cap 3, the construction of which will hereafter be more speciically described, may either be screwed upon the bottom of the casing or may simply be driven into position, this last-named construction being the one shown in the drawings. The circular closure plate or valve 7 provided with the aperture S is placed above the bottom cap 3. The plate bears a pin 17 which is received within the slot 16 upon the arm 13. To this arm 13 is connected the boss 14, within which there is formed the hexagonal aperture 15. It will be noted that up to this point the invention has been described using the same reference numerals as those employed to denote like parts in the aforesaid application, Serial Specification of Letters Patent.

Application 'filed June 12, 1913.

'Patented Aug. 1S, 1914.

serial no. 773,133.

No. 643,002, wherein the construction and operation oi' said parts are more specifi tally described.

Projecting outwardly 'from the casing l, and ijn'eierably il'ormed integral therewith, are large ears or plates 18. Since the device in its completed form is usually several inches in diameter, the particular stave which is provided with the bung-hole might be unnecessarily weakened by the boring ot' a large bung-hole. In the drawings, a fragment oil the stave 19 which is bored is shown in. Fig. 1 ol. the drawings, and the ears or projecting plates 18 protrude outwardly from the bung-closure beyond the edge ot' that stave. Said members 18, therefore, will rest upon and engage those staves which are respectively on one side or the other oi' the stave 19 and in this manner will serve to reinforce said stave and prevent the same 'trom caving in or breaking in case the weight of the barrel should happen at any time to rest upon the bored stave 19.

The casing 1 is provided with the perforation 2O which extends vertically therethrough, and within said perforation 20 the boss 14 is received, there being preterably a shouldered seat 21 in the perforation 20 to receive the boss 14. The circular closure plate 8 is directly beneath and in engagement with the boss 14 and arm 13, and said plate is caused to revolve when the arm 13 is rotated. Said arm is adapted to be carried -lrom the position shown in Fig. 1 to that depicted in Fig. 2. Then the parts are in the position shown in Figs. 1 and 3, the perforation 8 in the rotatable plate 7 will register with the opening 20, but when the parts are in the position of Fig. 2, the rotatable plate will close the opening 20.

The bottom plate 3, as shown in Figs. 4 and 5, is provided `with a boss 22 which is preferably screw-threaded on its interior wall, and the ring 23, which is provided with screw-threads upon its outer wall, is adapted to be received within said boss 22. Said ring 23 bears an annular seat 24, and upon this seat rests a ring or web of packing or the like. The screw threads upon the inner wall of the boss 22 do not extend to the top of the boss in Fig. 3 or to the bottom of the boss in Figs. 4 and 5, but at the bottom, Fig. 4, the inner wall of the boss 22 is smooth and the packing 25, therefore, is received between a smooth surface upon the wall of boss 22, and between a smooth surface on the outer edge of the ring 28. As clearly shown in Figs. 4 and 5, the web of packing projects a short distance beyond the ring 23 and the plate or cap 3, and is adapted to press against the closure plate 7 and in this manner to form a tight joint., 1When the parts are assembled, the central aperture through the ring 23 and the boss 22 is in registration with the aperture 20. When the movable parts are as depicted in Figs. l and 3, the aperture 8 will likewise be in registration with the aperture 2O and with the aperture through the ring 23; but when in the position shown in 2, the plate T will close the passageway through the device. Any liquor or liquid which may be within the barrel may press upon the under surface of the plate 7, but none of the liquid can escape because of the tight joint resulting from the engagement of the packing 25 upon the rotatable pl ate 7.'

A wrench with an ordinary hexagonal head may be used to open and close the valve, but since it is desirable to have such wrench used in conjunction with some kind of a lling head, a device like that shown in Fig. G may be employed. ln said gure there is shown a handle 26 which is attached to the casing 2i". The casing is of just the proper diameter to be received within the aperture 20, and at its lower end bears the hexagonal head 2S. llhe pipe 29 is secured in any suitable manner within the casing i7, some kind of a joint being used by which the pipe need not turn even though the handle and the casing are turned. lf so desired pipe may extend downwardly from the hexagonal h ead 28 to reach the bottom of the barrel, but such a pipe, which is not shown in the drawings, would have to be removed before the valve could be closed.

The ring 28 is preferably provided with slots or notches 8O to afford a grip` for whatever tool may be used to screw or unscrew the ring 23.

It is obvious that many changes in the details of construction and arrangement of parts may be made without departingg from the scope of the invention or of the various claims.

l claim as my invention:

l. A bung-closure comprising a casing, a bottom member received therewithin, a boss upon said bottom member, said casing and said boss being provided with registering apertures, a ring adapted to be secured within said boss, a packing adapted to be retained between the ring and the boss, a rotatable valve disposed between the top of said casing and said'boss, said valve being normally in engagement with said packing, and means to rotate the Valve.

it. A bung-closure comprising' a casing, a bottom member received therewithin, a boss upon said bottom member, said casing and said boss being provided with registering apertures, a ring` adapted to be secured within said boss,a packing adapted to be retained between the ring and the boss, those surfaces of the boss and of the ring whichengage said packing being smooth at the point of engagement, a rotatable valve disposed between the top of said casing and said boss, said valve being normally in engagement with said packing, and means to rotate the Valve.

j A bung-closure` comprising a casing having an aperture therethrough, a shouldered seat within said aperture, a bottom member received within the casing and having a packing member in connection therewith, a rotatable valve engaging said packing member and located between said bottom vmember and said seat, an arm, a boss thereupon, said boss being received within said seat, and means to rotate the arm, thereby to rotate the valve.

ln testimony whereof l have hereunto affixed my name in the presence of two witnesses.
