A New Method and Apparatus for Drawing or Pumping Beer and
other Liquids.
We, GEORGE HENRY KENDALL, of Firth Street Brass Works, Huddersfield, in
the County of York, Brass Founder and Finisher, and JOHN TYNE THORNTON, of
Paddock, near Huddersfield, aforesaid, Oil Merchant, do hereby declare the nature
of this invention to be as follows:-
In
Our invention has reference to a new means or method of drawing or raising beer,
and this we propose to do by operating the lifting pumps by hydraulic power.
carrying out our invention, we employ a small hydraulic cylinder with its accom-
panying piston.
A suitably arranged valve or valves is used in connection with the said cylinder,
which valve or valves is operated by the foot-or otherwise of the attendant, for
the purpose of admitting water to the cylinder and operating thereby the piston,
which in turn operates the lifting pumps. When the valve is operated in the reverse
direction, the action of the piston and pump is likewise reversed.
By the employment of hydraulic power to draw or raise beer, no exertion is
required on the part of the attendant, as is the case with the present method of
working pumps, as by our invention the pumps are raised up and down by the action
of the water.

COMPLETE SPECIFICATION.
A New Method and Apparatus for Drawing or Pumping Beer and
other Liquids.
We, GEORGE HENRY KENDALL, of Firth Street Brass Works, Huddersfield, in
the County of York, Brass Founder, and JoшN TYNE THORNTON, of Paddock,
near Huddersfield, aforesaid, Oil Merchant, 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 :-
Our invention has reference to a new means or method of drawing or raising beer,
and this we propose to do by operating the lifting pumps by hydraulic power. In
carrying out our invention we employ a small hydraulic cylinder with its accom-
panying piston and in connection therewith a suitably arranged valve or valves,
which, when operated by the foot or otherwise, of the attendant admit water to the
cylinder to operate the piston therein and the latter in turn operates the beer or
lifting pump. The reverse movement of the valve causes the return of the pistons
ready for the next up stroke.
In order the more fully to explain our invention we have annexed drawings
shewing in vertical section our improved apparatus for drawing or pumping beer and
other liquids by hydraulic power.
Referring thereto, A denotes a hydraulic cylinder provided at top and bottom
thereof with openings a and b communicating by pipes or passages a and b with
ports a2 and 3, respectively, in a valve box B cast or otherwise secured to or
supported at the side of the cylinder A. Capable of working in said valve box is
a valve C secured to a spindle D which passes through the gland or stuffing box c
and is connected at its lower end to a rod E coupled to a lever or treadle F by

page_text: which the valve is operated. The valve C is provided with suitable openings or
thoroughfares a3 and 63 for admitting water to the ports a², 62, respectively, and
with a groove or recess d to form a communication between one or other of the
ports a, 2, and the exhaust port e. f denotes the water inlet to the valve box
and the supply pipe.
The hydraulic cylinder A. has its accompanying piston G which is connected to a
piston rod H passing through each end of the cylinder and capable of sliding freely
through the stuffing boxes or glands and h, the said rod being made sufficiently
long to allow of one end thereof being connected to, or to form the piston rod of the
ordinary lifting or beer pump I so that the piston K therein may be operated by
and with the piston G in the hydraulic cylinder.
The action of the apparatus is as follows:-
Normally, the piston in the hydraulic cylinder is in the position shewn and the
pressure of water is on the upper side thereof, the valve C being in its lowest
position as indicated in dotted lines so as to leave the port a² open to the inlet f
When the pump is to be operated the attendant depresses the lever or treadle F
which raises the valve C to the position shewn in full line and closes the port a² to
the inlet and opens it to the exhaust port e, at the same time opening the port 62
to the inlet and closing it to the exhaust. The pressure of water from the supply
pipe thereupon passes through the opening 3, which is preferably of smaller area
than the port 2 in order that the up stroke of the piston in the beer pump may be
slower than the return stroke for purposes which will be obvious, and from thence
the water flows through the tube or passage b¹ to the opening below the piston G
which is thus forced upwards, the water above the piston being forced out through
the opening a passage or tube a¹ to the port a² from whence it is discharged through
the groove or recess d to the exhaust port e and conveyed away by a pipe el.
The piston G having been raised to its highest position and similarly raised the
piston K of the pump 1 and drawn up the beer, the lever or treadic F is released,
whereupon the pressure of water acting on the small ram L on the valve spindle
causes the valve C to be lowered again so as to close the port 62 to the inlet f and
open it to the exhaust and to open port a³ to the inlet and close it to the exhaust by
which means the piston G is forced downwards to the position shewn by the pressure
of water admitted to the upper end of the cylinder, whilst the water below the
piston is discharged through tube or passage port 62 and groove or recess d to
the exhaust e.
By the method and apparatus above set forth, no exertion is required on the part
of the attendant in drawing or pumping beer and other liquids as is the case at
present, the whole of the work being performed by the pressure of water.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The combination, with pumps for drawing or pumping beer, of hydraulic apparatus
for operating said pumps in the manner and for purposes substantially as herein
shewn and described.
