COMPLETE SPECIFICATION.
An Improved Tapping Device for Casks.
I, ANTON BECKER, of 23, Röhrergasse, Cologne, on the Rhine, in the German
Empire, Master Brewer, 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 device for drawing liquid from casks par-
ticularly from casks which are emptied under pressure. The said device consists
of three parts, a tap, a hollow plug entering the barrel and a casing screwed into
the cask and into which the tap and plug is screwed and my invention is charac-
terised essentially by the fact that the casing or sleeve screwed inside the cask
acts by means of a rubber disc fixed in the casing to make a perfectly tight joint
with the plug through which the liquid is to be drawn off.
Furthermore, the tap carries at its end an oval extension which is inserted
into the enlarged aperture (formed 'as an oval to correspond with the extension) of
the plug so that by screwing the tap into the casing the plug is screwed up,
whereby a connection is effected between the interior of the cask and the tap.
In the accompanying drawing which illustrates one form my invention may
assume, Fig. 1 is a view showing the casing and the plug in longitudinal section
and the tap in elevation, whilst,
Fig. 2 is a cross sectional view of the casing and plug on the line A-B of
Fig. 1.
The casing or sleeve a is screwed fast in a cask stave F. In this casing a is
inserted the plug b which can be partially screwed into a, and adjusted by means
of its screw thread on. It consists of a narrow tubular part which is closed
at its end, and terminates advantageously in a point and of an enlarged rear part 32
which is externally screwed. The narrow tubular part . is formed with any
desired number of apertures c. (according to requirement) four being shewn in
the present case. The liquid is able to flow through the apertures c into the interior
of the plug b when the plug, is sufficiently screwed up into the casing a.
part 6 of the plug is guided in and makes a tighter point with the casing a, whilst
its enlargement is screw threaded externally so as to screw in the screw threaded
interior of the casing a and thus allows of adjusting the plug to any degree of
entry into the cask. The tight joint of the part ¹ is effected by means of a rubber
disc d which bears against the shoulder of the casing and is pressed firmly up
by means of the screw-threaded portion f.
The
The screwing of the plug into the casing a is effected by means of the cock or
tap which is provided for this purpose with an oval extension i which is inserted
into a similarly shaped oval aperture of the enlarged part 2 of the plug 6 con-
nected to the extension i of the cock or tap h is a part m which is provided with
screwthreads corresponding to the internal screw threads of the casing a thus
allowing the cock or tap h being also screwed into the casing a.
If now the extension i of the cock h be inserted into the plug 6 and then be
screwed into the casing a the plug 6 will also be screwed up and the apertures c
will be brought into communication with the interior of the cask, so that the

page_text: liquid can then flow direct from the interior of the cask through the plug into
the cock h. The cock is of course always closed whilst it is being inserted so
that no liquid can flow out. The two handles o on the cock serve to facilitate the
screwing in of the said cock into the sleeve or casing a. A rubber disc or
washer 2' is provided to make a tight joint between the cock and the casing a.
Having now described the nature of this invention and in what manner the same
is to be performed I declare that what I claim is :-
1. A hermetically closing and drawing off device for casks, consisting of, in
combination, a casing a screwed fast in the cask and containing a rubber ring d
fixed inside the said casing, a plug with lateral holes c and adapted to screw up
in the casing a, making a tight joint with the said casing and a cock h adapted
to engage with and screw up the plug to allow of tapping the cask in a perfectly
tight jointed manner without waste of liquid.
2. In the device referred to in Claim 1, the arrangement of an oval extension
or shoulder on the cock h, which in screwing the cock into the casing or busha,
engages in a corresponding aperture k in the enlarged part 2 of the plug 6 for
the purpose of allowing of tapping the cask easily, substantially as described.
