strasse Berlin Germany "IMPROVEMENTS IN THE MODE OF AND IN APPARATUS
OR APPLIANCES FOR TAPPING CASKS AND OTHER VESSELS AND IN COCKS OR TAPS
FOR THE SAME" (A Communication from Anton Jos: Schaefer of New York in the
United States of America)
The object of this invention is to facilitate the tapping of casks and other vessels
to avoid the hammering in of the cock or tap the injury attendant thereon and to
prevent loss of contents. For this purpose there is placed in the head of a cask or
vessel a shell or ferrule provided with shutting off socket which by the insertion
of a suitable tapping cock or tap turns in such a manner that the passage for the
liquid is opened while by the removal of the cock or tap from the shell the passage
is closed.
A convenient way of carrying the Invention into effect is as follows:
Into the head of the cask the shell or ferrule which is made somewhat conical
is screwed or secured in any other suitable manner. This conical shell or ferrule
is closed at its inner end by a plate and near the latter it is provided with holes
which are preferably oblong. In the shell or ferrule is accurately ground in or
fitted a shutting off socket or second ferrule which is provided with holes corre-
sponding with the holes in the fixed ferrule. This inner socket turns in the outer

page_text: shell or ferrule and is held in its place by pins. These pins allow of the turning of
the inner socket or ferrule but prevent its axial displacement. The inner ferrule
or socket which is also closed only at one end, serves for the reception of. the tap
or cock and by means of the same can be so turned that the holes of the two
sockets or ferrules come opposite to one another so that the liquid contained in the
énsk or other vessel can flow through the said holes into the inner socket or ferrule
and thence into the cock. The tap or cock fits exactly in the inner socket and
is provided with two pins which correspond with grooves formed in the inner shell
or ferrule leading to the front rim of the same. The pins extend some distance
through these grooves in the outer ferrule or shell which also is provided with
longitudinal channels, which extend into cross channels so that a bayonet fastening
is made and the cock held fast in the socket.

It should be observed that the inner ferrule or socket by means of a screw and
nut may be held fast to the other socket or ferrule.

The object of this Invention is to facilitate the tapping of casks and other vessels
to avoid the hammering in of the cock or tap the injury attendant thereon and
to prevent loss of contents. For this purpose there is placed in the head of a cask
or vessel a shell or ferrule provided with shutting off socket which by the insertion
of a suitable tapping cock or tap turns in such a manner that the passage for the
liquid is opened while by the removal of the cock or tap from the shell the passage
is closed.
A convenient way of carrying the Invention into effect is as follows Into the
head of the cask the shell or ferrule which is made somewhat conical is screwed
or secured in any other suitable manner This conical shell or ferrule is closed at
its inner ends by a plate and near the latter it is provided with holes which are
preferably oblong. In the shell or ferrule is accurately ground in or fitted a
shutting off socket or second ferrule which is provided into holes corresponding
with the holes in the fixed ferrule This inner socket turns in the outer shell or
ferrule and is held in its place by pins These pins allow of the turning of the
inner socket or ferrule but prevent its axial displacement. The inner ferrulé or
socket which is also closed only at one end serves for the reception of the tap or
cock and by means of the same can be so turned that the holes of the two sockets
or ferrules come opposite to one another so that the liquid contained in the cask
or other vessel can flow through the said holes into the inner socket or ferrule and
thence into the cock. The tap or cock fits exactly in the inner socket and is pro-
vided with two pins which correspond with grooves formed in the inner shell or
ferrule leading to the front rim of the same The pins extend some distance
through these grooves in the outer ferrule or shell which also is provided with
longitudinal channels which extends into cross channels so that a bayonet fastening
is made and the cock held fast in the socket.
It should be observed that the inner ferrule or socket by means of a screw and
nut may be held fast to the other socket or ferrule.
In the accompanying drawing is represented such a tapping cock. Figure 1 is
a longitudinal section of the cock Figure 2 a front view of the shutting off box
Figure 3 a section on the line A. B. Figure 4 a section on the line C.D Figure 5
a section through the tapping cock and Figure 6 a modification.
Into the head of the cask is screwed or secured in any other suitable manner
the shell or ferrule a which is made somewhat conical. This conical shell or ferrule
is closed at its inner end by the bottom plate c and near the latter it is provided
with holes & which are oblong. In the shell or ferrule a is accurately ground in
the shutting off socket which is provided with holes g corresponding with the
holes d. The socket turns in the socket a and is held in place by pins i which
admit the turning but prevent actual displacement.
The socket f receives the tap h which is shown in dotted lines Figure 1 and can
by means of the same be so turned that the holes g and d come opposite each other,

page_text: the liquid in the cask then entering the interior of the cock h which latter has two
pins o which work in grooves r in the socket f leading to the front rim shown at
Figure 4. The pins o extend through these grooves into the shell a which is also
provided with longitudinal grooves which latter extend into cross channels &
Figure 4 forming a bayonet joint whereby the cock his retained in the socket f.
Figure 6 shows another mode of retaining the socket f in the socket a namely by
screw and nut m
Having now described and ascertained the nature of the Invention communicated
to me I declare that I claim
The shell a closed at one end. and adapted to be fixed in the cask and having
holes & in combination with the socket f turning in the shell and provided with
holes g and the tapping cock h having pins o by means of which the socket can
be turned substantially as set forth
