AN IMPROVED STOPPER FOR THE BUNG HOLES OF BARRELS OR OTHER VESSELS AND APPARATUS FOR FIXING THE SAME
Year: 1884

page_text: I, WILLIAM WEBSTER, of Park Mills, Leeds in the County of York, Engineer,
do hereby declare the nature of said invention for "AN IMPROVED STOPPER FOR
THE BUNG HOLES OF BARRELS OR OTHER VESSELS AND APPARATUS FOR FIXING
THE SAME" to be as follows:-
My improved stopper for the bung holes of barrels or other vessels and apparatus
for fixing the same, consists in a metallic shell the periphery of which is slightly
tapered and has a screw thread formed thereon for screwing into the stave of a
barrel or other vessel. This shell is suitably recessed on its outside and has an
opening in the centre through which liquid or other matter may be passed into the
barrel or vessel. The said central opening has a screw thread formed therein and
being less in diameter than the recess referred to, thus leaves a surface or soat
(plain or otherwise) around such contral opening. Into this central opening I
screw a metallic plug, which is provided with a head projecting around its screwed
part, and which forms on its underside a corresponding surface to that formed by
the bottom of the rocess in the shell. On the upper or outside surface of the plug
I form a suitably shaped recess by which it can be turned into position in the said
shell. Between the aforesaid surfaces formed by the bottom of the recess in the
shell and by the projecting head of the plug, I place a washer of leather or other
suitable material, which by the screwing home of the plug forms a perfectly tight
joint, all the parts being flush with the outside surface of the barrel or vessel.
In some cases I make the metallic shell with a small projecting flange, which
may either be sunk flush with the outsido of the barrel stave or vessel, or may be
allowed to project as desired.
I also make the shell without a screw thread on its periphery, but with a flange
projecting sufficiently for fixing by screws or rivets, (as is usual with ordinary
metallic bung hole bushes heretofore in use) These last two described forms of
shells aro recessed, screwed and fitted with the closing plug as above referred to.
My invention relates further to apparatus for fixing the said stopper in a barrel
or vessel and consists in an elongated plug which screws into the central hole of
the shell and is suitably arranged for the application of a key or lever for turning
the same, and also of a suitable wrench for screwing in the metallic plug.

I, WILLIAM WEBSTER, of Park Mills, Leeds in the County of York, Engineer,
do hereby declare the nature of my invention for "AN IMPROVED STOPPER FOR
THE BUNG-HOLES OF BARRELS OR OTHER VESSELS AND APPARATUS FOR FIXING
THE SAME," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:―
My invention has reference to an improved stopper for the bung-holes of barrels
or other vessels, and apparatus for fixing the same, the construction, arrangement
and operation of which will be readily understood by reference to the accompanying
sheet of illustrative drawings. and the following description thereof.
Fig. 1, is a sectional elevation, and Fig. 2, is a plan of my improved stopper
according to one arrangement. a, is a metallic shell slightly conical on its
periphery and threaded for screwing into the stave or other part of a barrel or
vessel, it is recessed on its outer side at b, to receive a leather or other elastic
washer c, and is formed with a central opening threaded to receive a screw plug d,
whereby the opening is closed. This plug is provided with a projecting head d²,
that takes into the recess b, and bears upon the washer c, so as to make an air-
tight joint. A square recess d³, is formed in the plug d, to enable it to be readily
fixed into the shell a,-e, is a small screw taking into a central threaded and
slotted opening in the plug d, the hend e', being large enough in diameter to close
the lower end of the slot d. This screw is squared at its outer end and fitted with
a key f, whereby it can be turned when it is required to vent a barrel or other
vessel, but I do not lay any general claim to this method of venting. Fig. 3,
shews in sectional elevation, and Fig. 4, in plan, a modification wherein the body
of the outer shell is slightly conical and plain, and has a projecting flange a', by
which it is secured to a barrel or vessel by means of screws or rivets as illustrated
at g, and h, respectively, and as practised with ordinary bung hole bushes.
There is a recess b, and central threaded opening for the reception of an
appropriately formed plug d, d, is a projecting head, and c, a leather or other
elastic washer, like that shewn in Fig. 1. A venting screw such as described with
reference to Fig. 1, may be used in this arrangement, i, is a lever or key provided
with a square projection ¹, to take into the recess in the head of the plug d, for
fixing the same in position. Fig. 5, shews an outer shell a, with a projecting rim
that may either be let into the stave of a barrel or vessel so as to be flush as at a³,
or may project therefrom as at a³.-Fig. 6, shews my apparatus for fixing the
outer shell a, of the metallic plug into position in the barrel or vessel. The part j,
is externally of the same form as the plug d, and is provided with a part k,
projecting therefrom and pierced or otherwise suitably formed to receive a lever or
key for turning the same,

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1st A stopper for the bung hole of a barrel or other vessel comprising a recessed
shell a, and a flanged plug à, suitable to receive packing between them (with or
without vent hole and screw e) the construction and arrangement being such as
above described with reference to and shewn in Figs. 1, and 2, or Figs. 3, and 4,
or Fig. 5, of the drawings.
2nd The apparatus described for securing the shell a, into the barrel or vessel.
