I, AUGUSTUS DANIEL ROTH of 3 Woodland Villas Blackheath in the County of
Kent Merchant do hereby declare the nature of this invention (a communication
to me from abroad by Fritz Volk of 1 Fahnenbergplatz Freiburg Baden Merchant)
to be as follows:-
This invention has for its object improvements in apparatus for forming bushing
and closing the bung holes and tap holes of casks.
In order to bring the hole in the stave to the proper form and dimensions to
receive the bush a tool is employed consisting of a hollow cone with a flange around
its base and a stem receiving a cross handle connected therewith.
There is a longitudinal slit through one side of the cone and through the flange
and in this slit a steel blade or cutter is fixed with its edge projecting somewhat
from the face of the cone. There are set screws passing through the walls of the
cone and abutting on the back of the blade and by these the blade can be set
forward to cause its edge to protrude more or less as may be desired. There are
other screws passing through the walls of the cone and through elongated holes in
the blade and screwing into a clamping plate which rests against the blade and
which when the screws are tightened nips the blade and so holds it securely in
place.
In the use of this tool the cone is introduced into the hole in the stave and is
turned round by means of the cross handle. The blade then pares the sides of the
hole and enlarges it until the flange comes to rest on the face of the stave. The
holes are then made accurately to the form and dimensions required. The tool
which produces the hole for the tap hole bush has a cylindrical shoulder of small
depth between the cone and the flange and the blade or cutter has a corresponding
shoulder which produces a like enlargement in the hole adapting it to receive the
tap hole bush hereinafter described.
The bung hole is bushed by screwing into it a conical ring or bush of malleable
cast iron.

page_text: This bush has a sharp V form thread on its exterior and a rounded thread within.
The bush receives a bung or stopper composed of a core of cast iron covered around
its periphery with a tough horny covering consisting of leather cuttings suitably
prepared and put on to the core with heavy pressure. The tools which apply the
covering to the core also form in it a screw thread corresponding to that within the
bush. The core is formed with ridges on its exterior so that it may not separate
from the covering in screwing the bung or stopper into and out of the bush.
In
the outer face of the core is a square or other recess to receive the key for
turning it.
The tap hole is in like manner bushed with a conical ring of cast iron with an
external screw thread. The bush has a rim at its outer end of the full diameter of
the thread or somewhat larger and in the face of this rim is a circular cavity
concentric with the tap hole. This cavity receives and truly centres the nozzle of
the corking apparatus which is used to force the cork into the tap hole when the
cask is filled so that the cork may pass accurately to its place. The bush receives
a cylindrical lining of tough material such as that with which the core of the bung
is covered. This lining forms a tight joint around the stem of the tap when the
cask is tapped. In the interior of the bush annular grooves are provided to retain
this lining in place.
The end of the bush within the cask is provided with an inwardly projecting
flange to prevent the lining being-pushed through the bush into the cask in the
operation of tapping.
This interior flange has two notches formed in it to receive the key by which the
bush is turned in screwing it into its place.

I, AUGUSTUS, DANIEL ROTH of 3 Woodland Villas Blackheath in the County of
Kent Merchant do hereby declare the nature of this invention (a communication
to me from abroad by Fritz Volk of 1 Fahnenbergplatz Freiburg Baden Merchant)
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
This Invention has for its object improvements in apparatus for forming, bushing,
and closing the bung holes and tap holes of casks.
In order to bring the hole in the stave to the proper form and dimensions to
receive the bush a tool is employed consisting of a hollow cone with a flange around
its base and a stem receiving a cross handle connected therewith.
There is a longitudinal slit through one side of the cone and through the flange
and in this slit a steel blade or cutter is fixed with its edge projecting somewhat
from the face of the cone. There are set screws passing through the walls of the
cone and abutting on the back of the blade and by these the blade can be set

turned round by means of the cross handle. The blade then pares the sides of the
hole and enlarges it until the flange comes to rest on the face of the stave. The
holes are then made accurately to the form and dimensions required. The tool
which produces the hole for the tap hole bush has a cylindrical shoulder of small
depth between the cone and the flange and the blade or cutter has a corresponding
shoulder which produces a like enlargement in the hole adapting it to receive the
tap hole bush hereinafter described.
The bung hole is bushed by screwing into it a conical ring or bush of malleable
cast iron.
This bush has a sharp V form thread on its exterior and a rounded thread within.
The bush receives a bung or stopper composed of a core of cast iron covered around
its periphery with a tough or horny or somewhat compressible covering: the
material known as vulcanized fibre is of such a nature and it serves the purpose
well but other substances may be employed. The tools which apply the covering
to the core also form in it a screw thread corresponding to that within the bush.
The core is formed with ridges on its exterior so that it may not separate from the
covering in screwing the bung or stopper into and out of the bush. In the outer
face of the core is a square or other recess to receive the key for turning it.
The tap hole is in like manner bushed with a conical ring of cast iron with an
external screw thread. The bush has a rim at its outer end of the full diameter
of the thread or somewhat larger and in the face of this rim is a circular cavity
concentric with the tap hole. This cavity receives and truly centres the nozzle

This interior flange has two notches formed in it to receive the key by which
the bush is turned in screwing it into its place.
In order that my said invention may be most fully understood and readily
carried into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of a tool employed in fashioning the tap hole to
receive the bush.
Figures 2.2ª 2b˚ are transverse sections of the same on the line A A, B B and C C.
in Figure 1.
Figure 3 is an elevation. Figure 4 a plan and Figure 5 a transverse section of
the bush for the bung hole.
Figure 6 is an elevation. Figure 7 a plan and Figure 8 an underside view of
the bung or stopper. Figures 8* show the covering separately. Figure 9 is an
elevation. Figure 10 is a plau and Figure 11 a vertical section of the bush for the
tap hole. Figures 12 show the lining for this bush. Figure 13 is a transverse
section showing the bush in place in the stave and with the lining within it.
Figure 14 is an elevation of the tool employed to screw the bung or stopper and
also the bush to their places.
Figure 15 is an elevation of the tool employed to screw the tap hole bush into
its place.
Figure 16 is an elevation of the tool employed to force the lining of the tap hole
bush to its place within the bush.
In Figures 1 and 2 a is the cone of the tool. 6 the projecting flange. c the
cylindrical shoulder between the cone and the flange. d the socket for the cross
handle. e the longitudinal slit in the cone and flange. f the cutting blade.
gg the screws by which the blade is adjusted so that its edge may project to a
suitable extent. hh are the clamping screws passing through the blade and
screwing into the clamping plate i. The knife can be readily removed and when
it has become blunt it can be replaced by another, and the first can be resharpened
at leisure.
The metal bung hole bush j is clearly represented by the Figures 3, 4 and 5 and
further description of it is unnecessary.
In Figures 6, 7 and 8-k is the metal core of the bung or stopper. k¹ the key
hole therein and k² k² the ribs or ridges on its exterior to prevent it turning within
its covering. is the covering. This covering which may be of vulcanized fibre is
made to the form indicated by Figures 8× it is soaked in water to soften it and
then the core k is forced into it. Then to make the covering grip closely upon the
core and to form on its periphery the external screw thread corresponding to
that in the bush j it is forcibly screwed into a tapering mould or socket within
which there is a corresponding screw thread. Here it is left until the covering
is dry and set. Artificial means may be resorted to if desired to accelerate the
drying.
The screw threads fully fill the corresponding threads in the bush so that
the covering material is compressed as the bung or stopper is screwed home, all the
parts being slightly tapered as is the socket or mould in which the exterior of the
covering is moulded.

page_text: The screw thread on the exterior of the bung or stopper and within the bush
may in some cases be omitted: the metal part k being then made so that it can be
laid hold of with tongs and drawn out.
In Figures 9, 10 and 11 which show the tap hole bush m¹ is the external screw
thread, m² is the cylindrical rim, m³ is the concentric circular recess within this
rim to guide the nozzle of the corking apparatus. m³ are the grooves to keep the
lining in place. m³ the inwardly projecting flange to prevent the lining being
driven into the cask. m³× are notches in the flange m³ to receive wings on the
key shown by Figure 15 by which the bush is screwed into its place in the stave.
The lining shown by Figures 12 and 13 may be made of the same composition
as that employed for covering the bung or stopper, it is softened by soaking in
water and is then forced into its place by means of the tool shown by Figure 16.
The bung hole may be bushed and lined in like manner.
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:-
1. A tool for fashioning the bung holes and the tap holes of casks to prepare
the same to receive bushes; such tool being a cone a to enter the hole, and a
flange 6 limiting the distance it can enter, a longitudinal slit e in the cone and
flange a cutting blade f secured in the said slit and a cross handle by which the
tool is turned to cause it to operate all substantially as herein described.
2. A bung or stopper consisting of a metal core k, covering l, and screw thread l
therein substantially as described.
3. The combination of the parts j, k, and 1 substantially as described.
4. A tap hole bush consisting of a metallic ring with internal screw thread m¹
and especially having an internal flange m³ preventing the lining n being driven
into the interior of the cask substantially as described.
5. The combination in a tap hole bush of the parts m³, m², m³, m³, m³, and n,
substantially as described.
6.--The combination with the bush for the bung hole or tap hole of a cask of a
compressible horny lining substantially as described.
7. The combination in a stopper or bung for a cask of a metal core k and a
compressible covering & substantially as described.
