IMPROVEMENTS IN APPARATUS FOR AERATING MALT AND OTHER LIQUORS
Year: 1885

page_text: I, GEORGE BARKER, of the Crown Hotel, Higher Ince, near Wigan in the
County of Lancaster, Publican, do hereby declare the nature of said invention
for "IMPROVEMENTS IN APPARATUS FOR AERATING MALT AND OTHER LIQUORS" to
be as follows:-
This Invention relates to apparatus for attachment to the mouthpiece or nozzle
of taps employed in connection with beer pumps and has for its object the
disturbing of the liquor and the introduction of air therein as it issues from the
tap. I employ a mixing chamber or box preferably in the form of a hollow
sphere made in two halves screwed together. The upper half of the chamber
screws on to the nozzle of the tap, the lower half being provided with a stand
pipe (serving also as the outlet) projecting about half way up the interior of the
chamber. The stand pipe carries a bell or semi-spherically shaped cap having holes
or perforations through its lower flat side which open into an inner space or cavity
surrounding the upper end of the stand pipe. The cap is screwed upon the outside
of the stand pipe and is thereby capable of adjustment to the required height
according to the amount of air to be introduced.
By causing the liquor to be passed through a mixing chamber arranged as above
described the liquor is disturbed and the air introduced at each stroke or pull of
the pump at its point of exit from the tap.

I, GEORGE BARKER, of the Crown Hotel, Higher Ince, near Wigan, in the
County of Lancaster, Publican, 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:-
This Invention relates to apparatus for attachment to the mouthpiece or nozzle
of taps employed in connection with beer pumps and has for its object the
disturbing of the liquor and the introduction of air therein as it issues from the tap.
The accompanying drawings illustrate the nature and details of my said
invention. Fig. 1 is a side view of a beer pump having my improved aërating
apparatus attached to the nozzle a of the ordinary tap. Figs. 2 and 3 are
respectively side and plan views of the apparatus; Fig. 4 is a vertical section;
Fig. 5 an interior plan view; and Fig. 6 a sectional view shewing the several
parts of the apparatus detached from each other.
I employ a mixing chamber or box preferably in the form of a hollow sphere
made in two halves band b¹ screwed together. The upper half b of the chamber
screws on to the nozzle a of the tap, or on to a nipple g soldered thereto, the lower
part of the nipple being screw-threaded to fit the upper part of the chamber as
shown. Where more than one pump is employed a similar or other suitably
formed nipple may be attached to the nozzle of each of the taps so that one
mixing chamber may answer for the series by being transferred from one pump
to another as required. The lower half 61 of the chamber is provided. with a
stand pipe c (serving also as the outlet) projecting about half way up the interior
of the chamber. The stand pipe c carries a bell or semi-spherically shaped cap d
having holes or perforations e. e through its lower flat side which open into an
inner space or cavity f surrounding the upper end of the stand pipe. The cap d
is screwed upon the outside of the stand pipe and is thereby capable of adjustment
to the required height according to the amount of air to be introduced. Fig. 7 is an
underneath view of the cap d. The upper edge of the stand pipe is preferably
made with one or more grooves i so that, in the event of the cap being screwed
hard down upon the end of the pipe, provision is made for the escape of the liquor
as it is forced into the chamber by the pump. The cap d is preferably employed
as being an adjustable intercepting medium whereby to regulate the amount of air
with which the liquor at each stroke of the pump is to be charged. The cap may,
however, be dispensed with, in which case the stand pipe c may be made up or
covered at its upper end with wire gauze or pierced or drilled with small lateral
holes or ducts for the egress of the liquor.
Where the parts are screwed together an intervening washer h of india-rubber or
other suitable material is employed to ensure the requisite air-tight joint. The
apparatus as above described by having a suitably formed outlet or mouth piece
is adapted for bottling purposes, that is to say, for charging the liquid with air as
it enters the bottle from a cask or other vessel,

the pump at its point of exit from the tap.
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. The use or employment in apparatus for aërating malt and other liquors of a
mixing chamber substantially such as described with reference to and shown in the
drawings.
2. Apparatus for aërating malt and other liquors constructed and arranged as
shewn and described.
