PROVISIONAL SPECIFICATION left by the said Peter James Catterall and
Edward Birch at the Office of the Commissioners of Patents on the 21st
July 1881.
PETER JAMES CATTERALL and EDWARD BIRCH, both of Manchester, in the
County of Lancaster. "AN IMPROVED METHOD OF AND APPARATUS FOR RAISING
BEER AND OTHER LIQUIDS."
The object of our Invention is to raise beer or other liquid to the bar or other
part of an hotel or other building without the exertion of hand labour.
We use a chamber placed in the cellar to the upper part of which is connected a
pipe (in which is a valve) terminating in the bar or other room; this chamber may
be globe shaped and made in two halves, divided horizontally, secured together by
bolts passing through flanges; also connected to the upper part of the chamber is
a pipe (in which is a valve) connecting the chamber with the barrel containing
the beer; we place a diaphragm of india rubber or other flexible material in the
chamber; the edges of the india rubber is held between the flanges, and the
diaphragm rests in the lower part of the chamber; to the lower part of the
chamber is connected a water supply pipe provided with a tap or valve which
may be double acting to admit or discharge water.
The beer from the barrel fills the chamber, and the valve in the pipe prevents it
from returning to the barrel; when it is desired to draw beer in the bar, water is
admitted to the lower part of the chamber, and the pressure of the water is.
sufficient to force the beer up the pipe to the bar; the india rubber prevents the
water mixing with the beer; when sufficient beer has been drawn the tap in the
water supply pipe is turned, allowing the water to escape from the lower part of
the chamber, and the chamber is again filled with beer from the barrel.
We use enamelled pipes conveying the beer or other fluid from the barrel to the
bar to avoid injury to the flavor. The chamber through which we convey the :
beer to the tap may be of any suitable shape, and a piston or other equivalent
might be used instead of the diaphragm; the chamber and the barrel containing
the beer may be in the cellar or in any other convenient place or position; other
liquid might be used instead of water to raise the beer or other liquor.

PETER JAMES CATTERALL and EDWARD BIRCH, both of Manchester, in the
County of Lancaster. "AN IMPROVED METHOD OF AND APPARATUS FOR RAISING
BEER AND OTHER LIQUIDS."
The object of our improvements is to raise beer or other liquid from a barrel or
vessel in the cellar, store-room, or other place, to the bar or other part of a hotel or
building without the exertion of hand labour.
We use a chamber placed in the cellar, to the upper part of which is connected a
pipe (in which is a back pressure valve) terminating in the bar or other room. This
chamber may be globe shaped, and made in two halves divided horizontally, secured
together by bolts passing through flanges; also connected to the upper part of the
chamber is a pipe (in which is a back pressure valve) connecting the chamber with
the barrel containing the beer. We place a diaphragm of india-rubber or other
flexible material in the chamber. The edge of the india-rubber is held between the
flanges, and the diaphragın rests in the lower part of the chamber. To the lower
part of the chamber is connected a water supply pipe provided with a tap or, valve,
which may be double acting to admit or discharge water. The beer from the barrel
fills the chamber, and the valve in the pipe prevents it from returning to the barrel.
When it is desired to draw beer in the bar, water is admitted to the lower part of
the chamber, and the pressure of the water is sufficient to force the beer up the pipe
to the bar; the india-rubber prevents the water mixing with the beer. When
sufficient beer has been drawn the tap in the water supply pipe is turned, allowing
the water to escape from the lower part of the chamber, and the chamber is again
filled with beer from the barrel.
We use enamelled pipes for conveying the beer or other liquid from the barrel to
the bar to avoid injury to the flavor. The chamber through which we convey
the beer to the delivery tap may be of any suitable shape, and a piston or other
equivalent might be used instead of the diaphragm. The chamber and the barrel
containing the beer may be in the cellar or in any other convenient place or
position. Other liquid might be used instead of water to raise the beer or other
liquor.
And in order that our Invention may be fully understood, and readily carried
into effect, we will describe the accompanying Sheet of Drawings, reference being
had to the figures and letters marked thereon.
r
Fig. 1 is an elevation of the entire apparatus; Fig. 2 is a view showing two
chambers (one in section) used in raising the liquid, and a longitudinal section of
the back pressure valves, through one of which the liquid is admitted to the
chamber, and through the other the liquid is forced to the bar or delivery tap;
Fig. 3 is a section of the three-way tap that admits and discharges the water used
to raise the beer or other liquid.
Similar letters refer to similar parts throughout the several views.
a is the stillage; b is the barrel containing the beer or other liquid to be raised.
To the tap of this barrel is connected one end of the flexible tube c, the other end
of which is connected to a back pressure valve d communicating with the upper
part of the chamber e. This chamber is made in halves, and a diaphragm f of
india-rubber or other pliant or flexible material is fitted in the chamber, the
periphery of the diaphragm being even with the periphery of the flanges of the
halves of the chamber which are then bolted together. This diaphragm effectually
prevents any liquid admitted to the upper part of the chamber e from mingling

page_text: with the water admitted to the lower part of the chamber e. The upper part of
the chamber e communicates through the valve g and pipe with the delivery tap i.
The lower part of the chamber e is fitted on a water chest j, to which water is
admitted through a three way tap k and supply pipe from the cistern m. The
tap has a weighted lever n (partly shown in dotted lines on Fig. 3); to this lever
is attached one end of a wire or cord o, the other end of which is fastened to a
treadle p near the floor below the tap i. The tap is for convenience connected to
the chest j by a short elbow, and to the lower part of the tap is connected a waste
pipe 9.
The mode of operation is as follows:-The beer flows from the barrel b through
the tube c and valve d and fills the chamber e, pressing the diaphragm finto the
position shown on Fig. 2. When it is wished to draw beer the tap i is opened, and
the treadle is operated to turn the three-way tap / so as to admit water from
the cistern m through the pipe 1, tap , and chest into the lower part of the
chamber e. The pressure of the water forces up the diaphragm f, and raises the
beer through the pipe h, and delivers it through the tap i
The back pressure
valve d prevents any beer from being forced back into the barrel. When sufficient
beer has been drawn the treadle p is released, and the weighted lever n brings the
tap into the position shown on Fig. 3, and shuts off the supply of water through
the pipe 7, and allows the water to escape from the chamber e and chest j through
the waste pipe q, and the beer from the barrel b again fills the chamber e.
We use
enamelled pipes to convey the beer or other liquor from the barrel to the delivery
tap to avoid injury to the flavor.
Any desired number of chambers e may be fitted on the chest j, each chamber
being connected to a separate barrel or vessel containing any kind of liquid to be
raised, and to a separate tap to deliver the liquid, the water supply being common
to all the chambers fitted on the chest. The chamber e may be of any convenient
shape, and the diaphragm of india-rubber or other material may be fitted in the
chamber in any suitable manner. A cylindrical chamber might be used fitted with
a piston instead of a flexible diaphragm. The water may be supplied to the
chamber e from any convenient source instead of the cistern m, but the pressure
must always be sufficient to raise the beer or other liquid from the chamber to the
tap i.
Having stated the nature of our Invention, and described the manner of per-
forming the same,
We declare that we claim,
The chamber e provided with the diaphragm f and with the back pressure
valves and g, one portion of the said chamber communicating with the barrel b
or other vessel containing beer or other liquid to be raised, and also communicating
with the delivery tap i, and the other portion of the chamber communicating with
a water supply pipe provided with a tap to admit and discharge the water,
substantially as and for the purpose shown and described.
In witness whereof, we, the said Peter James Catterall and Edward Birch,
have hereunto respectively set our hands and seals, this Nineteenth day of
January One thousand eight hundred and eighty two
