Improvements in Devices for Closing the Bung Holes of Casks,
Barrels, and the like.
We, CARL KÜHNER, Bung Manufacturer, and JOSEF SCHMATZ, Machine
Manufacturer, both of Johnsdorf near Brüx, Bohemia, Austria, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The present invention relates to a closing-device for casks and the like for the
purpose of effecting a simple and absolutely tight closing of bung-holes which bas
not been possible by the method, hitherto employed, of closing bungholes by
driving plugs into them, and which had another great disadvantage of making the
removal of the plugs extremely difficult.
In the present invention the tight closing is effected simply by compressing, by
means of a screw and two central superposed parts or plates provided with flanges
a packing (rubber) ring arranged between the plates which ring becomes pressed
against the walls of the hole or bush in the barrel and in this manner effects an
absolutely tight closing.
In the accompanying drawing
Figure 1 shows the closing device, in section, inserted into the bunghole, the
packing ring not being compressed,
Figure 2 shows the same, the ring being compressed and in use,
Figure 3 being a plan.
The closing device according to the present invention chiefly consists of three
parts.
A is the bung hole bush screwed into the cask and slightly tapered inside.
The closing device proper consists of an upper part or plate B and a lower part C
which are connected together by a screw D which passes loosely through the
upper part B and bears against it with its head and is screwed into a boss a of
the lower part c.
The screw D may be either rivetted over at its lower part
may be provided with a pin (Figure 2).
(Figure 1) or
The upper part B of the closing device fits with its projecting edge within a
correspondingly formed flange on the lower part C and the two parts are hollowed
out on their circumference so that a hollow space is formed which is filled with the
packing ring c (say of rubber). When the device is to be used, the parts B and C
are separated by unscrewing the screw D, packing ring c (say of rubber) is
placed round the outer edge 6 of the upper part B, said downward projecting edge
being preferably made of such width that the lower part C can only slightly
overlap the edge 6 of the upper part B. The screw D passes loosely through the
upper part B and is screwed into the boss a of the lower part and the whole device
is inserted into the annular bush A (Fig. 1).

By screwing the screw D further in, the parts B and C are drawn nearer
together and the ring c is compressed and, by further screwing of the screw D, is
pressed fast at all sides against the walls of the bush and thus effects a secure and
tight closing (Fig. 2). By unscrewing the screw D the closing device can be
easily withdrawn from the bush A.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
A closing device for casks barrels and the like consisting of two parts B and C
adjustable the one relatively to the other and surrounded by a packing ring c
whereby by drawing the two parts B and C together (by means of a screw D) the
packing is compressed and pressed against the walls of the bung-hole or bush
whereby an absolutely tight closing is effected.
