IMPROVEMENTS IN ENGINES OR APPARATUS FOR FORCING OR RAISING LAGER BEER AND OTHER LIQUIDS
Year: 1884

We JAMES FORMBY and CHARLES KEIZER of No 18 Regent Road, Liverpool,
in the county of Lancaster, Engineers do hereby declare the nature of our said
invention for IMPROVEMENTS IN ENGINES OR APPARATUS FOR FORCING OR RAISING
LAGER BEER AND OTHER LIQUIDS to be as follows:-
१
This invention relates to apparatus for forcing or raising lager beer and other
liquids from a cask or equivalent receptacle say from a cellar to a higher elevation.
The object is to provide engines or apparatus which will automatically do the
required work with steadiness and without undue disturbance of the beer or
liquid.
For the above purpose air or suitable gas such as carbonic acid is maintained at
the necessary pressure above the beer or liquid in the receptacle holding the same,
by means of a pump operated by a hydraulic engine connected to a towns or other
suitable supply. The water supply valve of the said engine is so connected by
levers rods or otherwise to the cock or tap used for drawing off of the beer or liquid
that the opening or closing of the said cock or tap admits water on one or other
side of the piston of the said engine.
The piston rod & the hydraulic engine is connected directly to the piston of a
double acting air pump from which a pipe or pipes is or are led to one or more
casks or receptacles. One or more pipes is or are led from each cask or receptacle
to a draw off tap or cock. Each draw off tap or cock is connected to the water
supply valve of the engine.
The action of the apparatus is as follows:-
When a tap or cock is opened to draw off beer or liquid the water supply valve
is also opened, water flows into the hydraulic cylinder on one side of the piston
and causes it to force air into the cask or receptacle as long as the beer or liquid
is being drawn off so keeping the pressure acting on the said beer or liquid uniform
or nearly so: by the closing of the said draw off cock or tap water is admitted to
the other side of the piston and the hydraulic and air pistons are caused to return
to their normal positions.

We JAMES FORMBY and CHARLES KEIZER of N° 18 Regent Road Liverpool
in the County of Lancaster Engineers, do hereby declare the nature of the
said invention for "IMPROVEMENTS IN ENGINES OR APPARATUS FOR FORCING OR
RAISING LAGER BEER AND OTHER LIQUIDS" 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 forcing or raising lager beer and other
liquids from a cask or equivalent receptacle say from a cellar to a higher elevation.
The object is to provide engines or apparatus which will automatically do the
required work with steadiness and without undue disturbance of the beer or
liquid.
For the above purpose air or suitable gas such as carbonic acid is maintained at
the necessary pressure above the beer or liquid in the receptacle holding the same,
by means of a pump operated by a hydraulic engine connected to a towns or other
suitable supply. The water supply valve of the said engine is so connected by
levers rods or otherwise to the cock or tap used for drawing off the beer or liquid
that the opening or closing of the said cock or tap admits water on one or other
side of the piston of the said engine.
The piston rod of the hydraulic engine is connected directly to the piston of a
double acting air pump from which a pipe or pipes is or are led to one or more
casks or receptacles. One or more pipes is or are led from each cask or receptacle
to a draw off tap or cock. Each draw off tap or cock is connected to the water
supply valve of the engine.
DESCRIPTION OF THE DRAWINGS.
Fig 1 is a vertical section and fig 2 a plan of my improved apparatus, a hydraulic
engine, 6 water supply, c exhaust, d controlling valve, e valve spindle, f crank on
valve spindle, g rod connecting the valve spindle crank to the beer tap h, i piston
of hydraulic engine, piston rod connected to the air pump piston k,l air pump,
m inlet valves for air, n exhaust valves opening to the pipe and branches o. The
pipe o is led to a barrel, and a pipe p leads from the said barrel to the tap h. The
pipe may be connected to several barrels, and each barrel may have a pipe leading
to a tap h.
The action is as follows:-
U.
When the tap his opened to draw off beer or liquid the valve d is opened
through the connections fg so that water flows into the bydraulic cylinder on one
side of the piston and causes it to force air or gas out of the pump into the barrel
and cause the beer or liquid to rise up the pipe p and out of the tap h. The
pistons i will travel upwards or downwards according as the valve d is moved in
one direction or the other by the tap h. The pressure on the beer or liquid is
uniform or nearly so.

page_text: A single acting pump may be used in which case the valve d and connections
will be arranged so as to cause the piston i to be moved to one end of its stroke
each time the tap h is closed.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is
Improvements in engines for forcing or raising lager beer substantially as set
forth.
