Year: 1873

page_text: LETTERS PATENT to Alfred Wharton, of Mirfield, in the County of
York, Dyer, and Thomas Lister, of the same Place, Gentleman, for
the Invention of "AN IMPROVED MEANS AND APPARATUS FOR RAISING
LIQUIDS."
Scaled the 22nd August 1873, and dated the 24th February 1878.
PROVISIONAL SPECIFICATION left by the said Alfred Wharton and
Thomas Lister at the Office of the Commissioners of Patents, with
their Petition, on the 24th February 1878.
WC, ALFRED WHARTON, of Mirfield, in the County of York, Dyer,
and THOMAS LISTER, of the same Place, Gentleman, do hereby declare
the nature of the said Invention for "AN IMPROVED MEANS AND APPARATUS
FOR RAISING LIQUIs," to be as follows:-
This Invention is especially applicable in cases where it is necessary
to raise liquids, such as beer, porter, or other liquids from the cellars to
upper stories, through pipes; and our improvements consist in the

page_text: employment of an air cylinder or vessol to contain compressed air
which is forced in by means of an ordinary air pump connected by pipe
and tap, or valve to regulate the supply and pressure of air. This
cylinder or vessel is connected by gutta percha, lead, or other pipe or
pipes to the bungs or upper part of the barrel or barrels containing the t
beer, porter, or other liquid to be raised. There are also pipes extending
from the barrels to the bar or other place required, being provided
with taps or valves in the usual manner. By opening the tap or valve
the compressed air in the cylinder will pass into the barrels and force
or raise the liquid contained therein to any height according to the 1
pressure employed. A pipe also extends from the air cylinder to tho
bar, and attached to which is an ordinary air or mercury gauge to
indicate the pressure of the air in the cylinder, which may be regulated
by means of the tap or valve in the pipe connecting the cylinder with
the barrels. The cylinder is also provided with another tap, by opening
which the compressed air may at any time be cut off from the barrel,
and thereby allow the beer, porter, or other liquid to descend from the
pipes into the barrels when not required to draw from them, and so keep
the same rood.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Wharton and Thomas Lister in the Great
Scal Patent Office on the 23rd August 1878.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wo, ALFRED

NOW KNOW YE, that we, the said Alfred Wharton and Thomas

3 manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, that is to say:-
This Invention is especially applicable in cases where it is necessary
to raise liquids, such as beer, porter, or other liquids from the cellars
to upper stories through pipes; and our improvements consist in the
O employment of an air cylinder or vessel to contain compressed air which
is forced in by means of an ordinary air pump connected by pipe and
tap, or valve to regulate the supply and pressure of air. This cylinder
or vessel is connected by gutta percha, lead, or other pipe or pipes to the
bungs or upper part of the barrel or barrels containing the beer, porter,
5 or other liquid to be raised. Thero are also pipes extending from the
barrels to the bar or other place required, being provided with taps or
valves in the usual manner. By opening the tap or valvo the com-
pressed air in the cylinder will pass into the barrels and force or raise
the liquids contained therein to any height, according to the pressure
0 employed. A pipe also extends from the air cylinder to the bar, and
attached to which is an ordinary air or mercury guage, to indicate the
pressure of the air in the cylinder which may be regulated by means of
the tap or valve in the pipe connecting the cylinder with the barrels.
The barrel is also provided with another tap, by opening which the com-
5 pressed air may at any time be let out from the barrel, and thereby
allow the beer, porter, or other liquid to descend from the pipes into the

page_text: barrels when not required to draw from them and so keep the same
good.
