Apparatus for Cleansing Casks.

I, FRANCIS ALLEN ROCHE, of 7, St. Luke's Place, in the City of Cork, Ireland,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an apparatus for cleansing casks.
According to the invention I provide an injector arrangement whereby steam
is first introduced into the cask to be cleansed so as to soften the impurities
adhering to the inside thereof after which a hot liquid is injected into the cask
by the steam jet so as to effectually clean the cask."
In carrying out the invention I advantageously construct my injector washing
or cleansing apparatus of an outer casing provided with inlets for steam and the
hot liquid and of a conical or other suitable plug adapted to turn in the said
casing similarly to the plug of an ordinary cock, the said plug being provided
with a central passage ending in a nipple formed upon the plug and having two
radial extensions of different cross sectional areas and both extending to the
periphery of the said plug and with a passage for placing the hot liquid inlet in
communication with the interior of the casing, the passages being so disposed
that the hot liquid inlet is opened simultaneously with the larger steam inlet.
To employ the device the apparatus is connected to a pipe which passes up into
the cask or barrel to be cleaned, the plug being normally in such a position that
both steam and hot water inlets are closed. The plug is now turned so as to
bring the smaller radial passage in the plug opposite the steam inlet thereby
causing a small jet of steam to pass into the cask and soften the impurities
adhering to the inside thereof. The plug is then turned further so as to bring
the larger radial passage in the plug opposite the steam inlet and at the same
time bring the hot water inlet opposite its passage in the plug in such a manner
that the full jet of steam which issues from the nozzle in the plug draws in a
supply of hot water, the temperature of which is increased by the steam with
which is mixes, and the mixture formed passing into the interior of the barrel
or cask to be cleaned.

in and by the following statement:

This invention relates to apparatus for cleansing casks, barrels and the like.
According to the invention I provide an injector arrangement whereby steam
is first introduced into the cask or the like to be cleansed so as to soften the
impurities adhering to the inside thereof, after which a hot liquid is injected
into the cask by the steam jet so as to effectually clean the cask."
In carrying out the invention I advantageously construct my injector washing
or cleansing apparatus of an outer casing provided with inlets for steam and the
hot liquid and of a conical or other suitable plug adapted to turn in the said
casing similarly to the plug of an ordinary cock, the said plug being provided
with a central passage ending in a nipple or nozzle and having two radial ex-
tensions of different cross sectional areas and both extending to the periphery
of the said plug and with a passage for placing the hot liquid inlet in communica-
tion with the interior of the casing, the passages being so disposed that the hot
liquid inlet is opened simultaneously with the larger steam inlet.
To enable my invention to be fully understood I will describe it by reference
to the accompanying drawing in which:
Figures 1 and 2 are vertical sections of the injecting device shewing the plug
in its two operative positions; and,
Figure 3 is a sectional view drawn to a smaller scale shewing the method of
employing the apparatus for cleansing the cask.
a is the outer casing and b and c are the steam and hot liquid inlets respectively
formed upon the said casing a. d is the conical plug which is adapted to be
turned in the said casing a similarly to the plug of an ordinary cock through
the medium of the squared projecting end with which it is provided. e is
the central longitudinal or axial passage formed in the plug and is the nozzle
which is screwed into the broad end of the plug d, the passage f in the said
nozzle being continuous with the above mentioned longitudinal passage e. g is
the larger radial passage extending from the longitudinal passage e to the peri-
phery of the plug and his the smaller radial passage also extending from the
said axial or longitudinal passage e to the periphery, the two passages g and h
being in alignment with one another and with the steam inlet b. is the passage
which is formed in the outside of the plug d for placing the interior of the
casing a in communication with the hot liquid inlet c.
The lower part of the casing is provided with a neck a¹, the area of which
contracts around the opening of the nozzle f so as to give the necessary injector
like action to the steam issuing from the nozzle. The lower end of this neck
is formed with an external screw-thread for enabling the apparatus to be screwed
to a pipe, such for example as the pipe shewn in Figure 3.
The arrows in the drawing indicate the direction of flow of the steam and hot
liquid.
To employ the device, the injector a is screwed to the pipe jas shewn in
Figure 3, which said pipe passes up into the cask or barrel A to be cleansed,
the end of the said pipe projecting into the cask being preferably provided with
a rose for distributing the fluid entering therein and the cask being held upon
suitable supports such as B, B; the plug d is, of course; normally turned into
such a position the none of the passages in the said plug are in communication
with the steam or hot liquid inlets in the casing. The apparatus being fitted in
position, the plug d is turned so as to bring the smaller radial passage in the
plug dopposite the steam inlet as shewn in Figure 1 thereby causing a small
jet of steam to pass into the cask and soften the impurities adhering to the
inside thereof. The plug d is then turned further so as to bring the larger
radial passage g in the plug d opposite the steam inlet b and at the same time
the passage i opposite the hot water inlet c as shewn in Figure 2 so that the full
jet of steam which issues from the nozzle f in the plug draws in a supply of hot
water through the said passage and inlet c, the temperature of which water is

page_text: increased by the steam with which it mixes and the mixture formed passing
through the pipe into the interior of the cask A. When the cask has been
sufficiently cleansed the plug is turned so as to cut off both steam and hot water
and the barrel can then be removed from its supports.
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. Apparatus for cleansing casks, barrels and the like comprising an injector
device consisting of a casing having a plug with passages which can be placed
in communication with a supply of steam and of a hot liquid in such a manner
that steam can first be introduced into the cask and the hot liquid then injected
into the same, substantially as, and for the purpose, hereinbefore described.
2. Apparatus of the kind described in Claim 1 comprising an outer casing
adapted to be fitted to a pipe leading to the cask barrel or the like to be cleansed
and having inlet openings for the steam and hot liquid respectively and a plug
turning in the said casing, the said plug having a longitudinal passage ending
in a nozzle, two radial passages of different diameters extending from the longi-
tudinal passage to the periphery of the plug in the plane of the steam inlet and
a passage for placing the interior of the casing into communication with the hot
liquid inlet, substantially as, and for the purpose, herein before described.
3. The apparatus for cleansing casks, barrels and the like, constructed sub-
stantially as herein before described and illustrated in the accompanying drawing.
