I, LOUIS MATHIEU REGNAC-PAILLE of Charleroi in the Kingdom of Belgium, do
hereby declare the nature of this invention to be as follows:-
My invention relates to an improved construction of automatic closing bung which
will operate with either absolute hermetic closure or, when required, with partial
closure only, such as during the fermentation of beer. The construction will be readily
understood on reference to the accompanying drawings in which Fig. 1 is a cross
section of the circular ring which is screwed in the cask, shewing the lower toothed
edges disposed as inclined planes, Fig. 2 is a plan view of the same, Fig. 3 is a cross
section of the bung proper shewing the air holes and their covering plate, Fig. 4 is a
plan view of the same, Fig. 5 is an elevation of the bung with its indiarubber
packing.
A is a metallic ring externally threaded to be screwed in the cask stave; the lower
edge D of the ring is shaped as a double inclined plane and it is provided with teeth
upon which slide two projections H of the bung. The lower part K of the ring is
grooved and is provided with an indiarubber ring C Fig. 2 making a tight joint.
The groove K is provided with two notches L through which pass the two projections H
of the bung.
It.follows from this arrangement that when the bung is placed in the ring A, the
projections H being passed through the notches L, if the bung is turned from left to
right, the projections pass along the inclined planes D of the ring, squeezing more
and more the indiarubber ring C between the conical part B of the bung and the
groove K, thus affording a closure which will be the more perfect, the farther the
bung turned. The teeth formed upon the lower edge of the inclined planes have for
their object to prevent the projections from sliding back and thus prevent any
loosening of the bung which might occur owing to impact or shaking resulting from
the removal of the cask.
The bung proper is composed of a disc M provided with a flange N the
upper part
of which widens in a conical surface B so as to more strongly compress the india-

page_text: rubber ring forming the joint. At diametrically opposite points of the disc Mare
two projections H which effect the pressing down of the bung as described. In the
centre of the disc is a threaded opening in which is screwed a bolt E the head of
which projects inside the bung; the lower end of this bolt is provided with a metallic
disc F upon which rests a leather washer I which pressing upon the edge J of disc M
effects the perfect closure of two or more openings G disposed in the interior of
edge
J and which establish communication from the inside of the cask to the atmo-
sphere. In order to close these openings G it suffices to rotate the bolt E until the
washer I presses sufficiently against the edge J. A nut O serves to maintain the
discs F and I in their respective positions. As shewn in Fig. 4 the bung is formed
with a square or polygonal recess in order that it may be rotated as much as necessary
by means of an appropriate key. Further, the notches L of the ring are intended to
receive an appropriate key in order to rotate the ring so as to screw it into the cask
stave. In order to fit this bung to a cask, the hole in the stave being prepared,
the ring A is first screwed tightly by means of a key inserted in the notches L; the
projections H are then inserted in the notches L and by means of another key the
bung is turned until the indiarubber ring C is sufficiently compressed to afford a tight
joint. During the fermentation and when it is necessary to evacuate the air or gas
contained in the cask, the valve F is unscrewed, thus opening the small holes G. A
great advantage of this arrangement is that it allows the easy clearing of these
openings when obstructed with yeast &c.
In order to enlarge the bung holes existing in casks where the automatic bung is to
be applied, a special boring arrangement is used that is illustrated in Fig. 6 by a trans-
verse section, Fig. 7 in plan, Figs. 8 and 9 shewing the cutters and Figs. 10 and 11
the borer carrier.
This tool is used as follows: The borer carrier F¹ is forced by its lower conical end
into the bung hole, then upon its cylindrical upper part the collar E¹ of the cutter
carrier A is passed. In the lower circular part of this latter are formed slots in order
to receive three cutters B fixed by means of set screws C so as, when the cutter
carrier is rotated by means of handles D D, to cut a hole in the stave wide enough to
permit the admission of the lower end of the threaded ring of the bung which is
securely screwed in place as above described. The spring J surrounding the cutter
carrier has for its object to automatically raise the cutting tool and to push out the
shavings which are cut by the action of the cutters and to prevent them from falling
into the cask.
Dated this 7th day of December 1886.

I, LOUIS MATHIEU REGNAC PAILLE of Charleroi in the Kingdom of Belgium
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:
My invention relates to an improved construction of automatic closing bung
which will operate with either absolute hermetic closure or, when required, with
partial closure only, such as during the fermentation of beer. The construction will be
readily understood on reference to the drawings accompanying my provisional Speci-
fication filed on the 7th December 1886, in which Fig. 1 is a cross section of the
circular ring which is screwed in the cask, shewing the lower toothed edges disposed
as inclined planes, Fig. 2 is a plan view of the same, Fig. 3 is a cross section of the
bung proper shewing the air holes and their covering plate. Fig. 4 is a plan view
of the same. Fig. 5 is an elevation of the bung with its indiarubber packing.
A is a metallic ring externally threaded to be screwed in the cask-stave; the
lower edge D of the ring is shaped as a double inclined plane and it is provided with
teeth upon which slide two projections H of the bung. The lower part K of the
ring is grooved and is provided with an indiarubber ring c, Fig. 3, making a tight
joint, this ring being by preference covered with woven fabric to prevent its
adherence to the iron when rusted. The groove K is provided with two notches L
through which pass the two projections H of the bung.
It follows from this arrangement that when the bung is placed in the ring A the
projections H being passed through the notches L, if the bung is turned from left
to right, the projections pass along the inclined planes D of the ring, squeezing
more and more the indiarubber ring c between the conical part B of the bung and
the groove K, thus affording a closure which will be the more perfect the farther
the bung is turned. The teeth formed upon the lower edge of the inclined planes
have for their object to prevent the projections from sliding back and thus prevent
any loosening of the bung which might occur owing to impact or shaking resulting
from the removal of the cask.
The bung proper is composed of a dise M provided with a flange N the upper part
of which widens in a conical surface B so as to more strongly compress the indiarubber
ring forming the joint. At diametrically opposite points of the disc M are two pro-
jections H which effect the pressing down of the bung as described. In the centre
of the disc is a threaded opening in which is screwed a bolt E, the head of which
projects inside the bung; the lower end of this bolt is provided with a metallic
disc F upon which rests a leather washer I which, pressing upon the edge J of
disc M, effects the perfect closure of two or more openings G disposed in the
interior of edge J, and which establish communication from the inside of the cask to
the atmosphere. In order to close these openings G it suffices to rotate the bolt E

page_text: until the washer I presses sufficiently against the edge J. A nut O serves to main-
tain the discs F and I in their respective position. As shewn in Fig. 4 the bung is
formed with a square or polygonal recess in order that it may be rotated as much
as necessary by means of an appropriate key. Further, the notches L of the ring
are intended to receive an appropriate key in order to rotate the ring so as to screw
it into the cask stave. In order to fit this bung to a cask, the hole in the stave
being prepared, the ring A is first screwed tightly by means of a key inserted in the
notches L.; the projections H are then inserted in the notches Land by means of
another key the bung is turned until the indiarubber ring c is sufficiently compressed
to afford a tight joint. During the fermentation and where it is necessary to evacuate
the air or gas contained in the cask, the valve F is unscrewed, thus opening the small
holes G. A great advantage of this arrangment is that it allows the easy clearing
of these openings when obstructed with yeast &c.
In order to enlarge the bunghole existing in casks where the automatic bung is to
be applied a special boring arrangement is used that is illustrated in Fig. 6, by a
transverse section, Fig. 7. in plan, Figs. 8 and 9 shewing the cutters and Figs. 10
and 11 the borer carrier.
This tool is used as follows: The borer carrier F is forced by its lower conical
end into the bung hole, then upon its cylindrical upper part the collar E¹ of the
cutter carrier A is passed. In the lower circular part of this latter are formed slots
in order to receive three cutters B fixed by means of set screws C so as, when the
cutter carrier is rotated by means of handles D D, to cut a hole in the stave wide
enough to permit the admission of the lower end of the threaded ring of the bung
which is securely screwed in place as above described. The spring J surrounding
the cutter carrier has for its object to automatically raise the cutting tool and to push
out the shavings which are cut by the action of the cutters and to prevent them from
falling into the cask.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
1. An improved construction of bung consisting of an external screwed ring A
having a groove K, and the lower edge of which has two notches L, and two hollowed
inclined planes D, in combination with a bung the upper part of which is conical
while the lower part is of disc form and has two projections H and is also provided with
two or more air holes G capable of being closed by discs F and I acted upon by a
screw bolt E, substantially as herein described.
2. A metallic bung wherein the closure is effected by means of a caoutchouc ring
covered with fabric arranged between two surfaces that are made to approach each
other by the action of projections on the moveable part sliding on hollowed inclined
planes on the fixed part substantially as herein described.
3. The construction of metallic bung having one or more central openings for the
escape of gas, and capable of being closed by a disc valve actuated by a screw bolt
substantially as herein described.
4. The use for making or enlarging bung holes of a tool consisting of an annular
cutter carrier A containing three cutters B and bearing against the borer carrier Fl
having a conical surface that is forced into the bung hole, a spring J being provided
for raising the cutting tool which is rotated by means of handles D D, substantially
as herein described.
