Improvements in Bung Hole Bushes.
I KUNO VESSELER of Milspe near Hagen, Westfalia, Germany, Manufacturer
o hereby declare the nature of this invention and in what manner the same is to be
erformed, to be particularly described and ascertained in and by the following
tatement:-
My invention relates to an improved bung hole bush the characteristic feature of
which consists in the use of an exchangeable, elastic lining, into which the bore

ole for the cork or for the tapping cock is drilled.
he hole the shape of the new bung hole bush at the inner side gives absolute
guarantee for tight closing and against flying out of the cork and on the other side
the lining prevents the cock from injury by holding it off from the metal of the
oush and it secures also tight fitting.
On the accompanying drawing
Figure 1 is a section of the bush with a cork driven therein along line I-I of
Fig. 2;
Figure 2 is a plan of the same;
Figure 3 is a cross section along line II-II of Fig.
Figures 4 and 5 show the lining, partly in section;
i
Figure 6 shows the new bung hole bush as applied with a tapping cock.
A is the casing or bush proper, it is slightly conical and provided with screw
thread; at the narrow side the casing is provided with a bottom B, bored through
centrally; the inner surface of the bush A is also provided with screw thread
nearly down to the bottom B. The lower or outer side of the bottom B is counter-
sunk, as will be seen from Fig. 1.
Into the metal bush A I put the lining D (Figures 1, 4 and 5) of wood or other
Buitable soft or elastic material, and I drive it firmly down to the bottom by means
of a screw E, having a central hole in the middle.
The bung hole bush described is fixed to a barrel in the usual manner and its
central hole in the lining is closed by a cork, which is driven in firmly so that its
outer end spreads out and fills up the widened part of the screw piece E, whereas
at the inner side the cork opens and the projecting spreading part thereof is pressed
against the countersunk at the bottom B of the bush by the pressure of the fluid
in the barrel thus assisting a close and tight shutting up; whilst at the same time
the enlarged inner part also prevents the cork from flying out of the bush and the
lining.
When a tapping cock is used, the shape of the screw piece E assists the driving
in of the cone of the cock and the lining D secures a close and tight fitting, so that
no fluid can escape along the sides of the cock. The lining also guards the cock
from injury, when driven in firmly, by its keeping it off from the hard metal of
the bush.
When the lining is damaged or worn it can easily be replaced by a new piece of
wood bored and cut to proper shape.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
A bung hole bush, A, having an exchangeable lining, D, of wood or other elastic
material, held therein by a piece, E, screwed firmly down upon the lining and

-driven into the central hole of the lining and the bush by spreading out is pressed
against the countersunk or conical surface of the bottom securing a tight fitting
and preventing the cork from flying out by the pressure of the fluid in the
barrel.
