Improvements in Tap Hole Closing Devices for Casks and Barrels.
We, WILLIAM HENRY BARRELL DAINTON of Silver Street, Uttoxeter, in
the County of Stafford, Brewer, and ARTHUR EDGAR DAINTON of 9 Stockwell
Park Road Brixton in the County of Surrey, Architect's Pupil, do hereby
declare the nature of this invention to be as follows:-
:—
The tap holes of beer casks or barrels are ordinarily closed with corks and tin
holders are
provided to receive extra corks for afterwards closing the empty casks.
When a cask is to be tapped, the tap is inserted, driving the cork into the cask.
Afterwards when the cask becomes practically emptied the tap is withdrawn, and
if then the tap hole be left open air and water are liable to enter the cask which
becomes foul and difficult to afterwards cleanse and render sweet enough to receive
more beer. The extra corks intended to be inserted in the tap holes when the casks
are empty, usually get lost.
Furthermore in order to make a tight joint between the cask and the tap it is
usual to employ paper as packing and in this way it happens that bits of paper get
into the casks.
Now this invention is designed to obviate these objections. For this purpose the
tap hole is provided with a cover or closure faced with elastic material such as
india rubber and adapted in one position to close the tap hole and in another position
(to which the cover or closure can be moved by turning about a pin or stud or by
sliding in suitable guides) to expose the tap hole-the arrangement being such that
a stop is provided against which the cover closes; and that when it is open it will
be suitably supported to prevent its being knocked off. To obviate the use of
paper there is provided around the tap hole at the outer side of the cask end a
sheet or piece of elastic material such as india rubber having through it a hole of
smaller diameter than that of the tap hole at its outer end, but about the same
diameter as the inner end of the tap hole; the outer end of the tap hole is of a
rounded form to receive and support the elastic material when the tap is being
inserted. A plate or ring between which and the cask end the elastic material is
interposed (and to which plate the cover or closure before referred to is or may be
applied) serves to support the elastic material when the tap is being withdrawn.
The invention may be carried out in various forms.

Improvements in Tap Hole Closing Devices for Casks and Barrels.
We, WILLIAM HENRY BARRELL DAINTON of Silver Street, Uttoxeter, in
the County of Stafford, Brewer, and ARTHUR EDGAR DAINTON late of
9 Stockwell Park Road, Brixton, in the County of Surrey, now of 40 Navarino
Road, Hackney, in the County of Middlesex, Architect's Pupil, 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
Estatement:
The tap holes of beer casks or barrels are ordinarily closed with corks, and tin
holders are provided to receive extra corks for afterwards closing the empty casks.

Now this invention is designed to obviate these objections. For this purpose the
tap hole is provided with a cover or closure (hereinafter called a cover) faced with
elastic material such as india rubber and adapted in one position to close the tap
hole and in another position (to which the cover can be moved by turning about a
pin or stud) to expose the tap hole, the arrangement being such that a stop is pro
vided against which the cover closes, and that when the cover is open it will be 15
suitably supported to prevent its being knocked off. To obviate the use of paper-
there is provided around the tap hole at the 'outer side of the cask, end a 'sheet or
piece of elastic material such as india rubber having through it a hole of smaller
aincter than that of the tap hole at its outer end, but about the same diameter as
the inner end of the tap hole; the outer end of the tap, hole is of a rounded form to 20
receive and support the elastic material when the tap is being inserted. A plate or
ing between which and the task end the 'elastic material is interposed, and to "
which plate the cover, before referred to is or may be applied, serves to support the u
elastic material when the tap is being withdrawn.

The cover at its inner side is provided with a tongue or projection-7 arranged to
take under and work against a slightly inclined surface 8 that is formed on that 40
side of the plate 3 that is nearly opposite to the pivot pin 2, and terminates in a
shallow recess 9 (Fig. 3). In the inner surface of the cover is fixed a disc 10 of
elastic or yielding material,such as india rubber. The outer surface of this disc,
as well as that of the annular projecting part 3 of the plate 3 against which the
disc is to bear, is made slightly inclined to the axis of the hole 6, so that when the 45
cover is moved into its closed!positionf'shown in Figs: 2, 3, and 4, the said disc 8
will be fixed tightly against the said annular part so as to form a tud
form a fluid tight
joint therewith, and effectually prevent the passage of air or water into the cask
through the hole 6. As the cover is nearing its closed, position the tongue 7. will
slide against the inclined surface 8 and thereby act to draw down and compress the 50
disc 10 against, the annular, part 3 and just as the cover arrives in its closed position
the tongue will spring into the recess 9 and effectually prevent the cover from
becoming accidentally opened. The cover can nevertheless be readily opened by
applying pressure to it literally in a direction opposite to the
e to the closing movement,
namely in the direction of the arrow Fig. 2.

11 is a sheet of elastic material such as india rubber, fixed between the cask 5
and the plate 3 and provided at the centre with a boss 11" the hole through which
is in line with the hole 6 and of a size to tightly fit the barrel portion 12" of a
tap 12 when the same is forced tightly therethrough as shown in Fig. 5. The
outer end of the hole 6 may advantageously be made of bell mouth form, as shown,
to receive and support the boss 11 whilst the tap is being forced into place, whilst
the annular part 3 of the plate 3 serves to support the boss when the tap is being
withdrawn.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what we
claim is :
1. A closing device for a cask or barrel comprising a cover or closure faced with
elastic material, a perforated plate capable of being fixed to a cask or barrel with
its opening in line with the tap hole therein and on which the cover or closure is
mounted in such a manner that when it is moved into its closed position it will be
pressed tightly against the plate and effectually close the hole therethrough, and a
sheet or piece of elastic material formed with a perforated part adapted to tightly
fit the barrel portion of a tap substantially as herein described.

2. The improved closing device for a cask or barrel, constructed arranged and
operating substantially as described and shown.
