Improvements in Apparatus for Aerating and Drawing off
Liquids.
I, SAMUEL MARKS, of the New York Brewery, Newtown, near Sydney, in tho
Colony of New South Wales, 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:-
Heretofore in retailing liquids which are required to be charged with air or gas it
has been customary to draw them off from a vessel reservoir or font in which they
have been previously charged with gas or in which they have of themselves generated
the gas but it has been found that with certain classes of liquids and especially with
malt liquors that retaining the gas in the bulk of such liquids has a deleterious effect
upon them-Now my invention has been devised in order to obviate the necessity
of having a large quantity of liquid under the influence of the gas or air and so that
apportionments or small quantities as they are drawn off may be aerated before being
distributed By this means I am enabled to aerate glasses or small quantities of beer
or other liquids as they are drawn from the cask and supplied to the customer and I
am further enabled to aerate heer or other liquids as they are drawn from the cask
or reservoir and being bottled.
These improvements in apparatus for acrating and retailing liquids consist
essentially in the combination and arrangement with a vessel adapted to be filled from
a reservoir or container of unaerated or partially aerated liquid of a font or reservoir
containing air under pressure carbonic acid gas or natural or other gases with or
without a holding liquid in such a manner that when the former is charged with
liquid from the said reservoir or supply a small quantity of the air or gas or of the
charged liquid from the latter may be allowed to enter and aerate said charge and
when said charge is drawn off the vessel may be recharged with liquid and with gas
as often as desired.
But in order that my invention may be clearly understood I will now describe
the same with reference to the drawing herewith which shows my improved combined
retailer and aerater for liquids attached in duplicate to the bar or counter of a hotel
or shop-A is a reservoir or container-B a pump or "beer pull"-Ca retailing
vessel and D a font or reservoir containing preferably a quantity of the beverage to
be retailed charged with carbonic acid gas or containing air or gas under pressure-
A' is supply pipe-B₁ discharge pipe-B2 tray for drippings-(distributing tap--
C pressure gauge-D₁ gas supply pipe-D tap or cock therein-In operation the
font or gas reservoir D being charged with gas or liquid under pressure is attached
to pipe D and a charge of liquid being drawn by pump or
beer pull B (of any
well known construction) to fill vessel C the tap D2 is turned on until sufficient gas
or liquid charged with gas has entered into the liquid in vessel C a fact ascertainable
by watching gauge (when tap D is turned off-The liquid thus treated by means
of the gas or the liquid charged with gas may be drawn off in small quantities through
tap C When required the pipos A and D₁ may be attached to fresh reservoirs A
and fonts D respectively.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is: :-
First. The combination and arrangement with a retailing vessel adapted to be filled
from a reservoir or supply of liquid of a font or reservoir from which charges of air
or gas or preferably liquid containing gas may enter said vessel substantially as

page_text: Second. The combination and arrangement with a reservoir A with or without a
pump or beer pull B of a retailing vessel C and a reservoir D containing gas or liquid
charged with gas and having stop cock D substantially as herein described and
explained and as illustrated in the drawings.
