PROVISIONAL SPECIFICATION.
An Improved Apparatus with Automatic Water Cistern for Raising
or Forcing Beer or other Liquids.
I, WILLIAM Ross, Junior, of 62 Saint Vincent Street, Glasgow in the County
of Lanark, Engineer, do hereby declare the nature of this invention to be as
follows:
This invention relates to improvements in apparatus for raising or forcing beer
and other liquids to the point of drawing off or discharge and the improved
apparatus consists of an automatically acting water cistern or tank situated at a point
higher than the point of discharge and from the bottom of which a pipe extends
downwards to near the bottom of an enclosed tank or vessel at whose side and also
near the bottom a hole or opening is made or a tube leading to a drain is connected
this hole or tube heing of lesser area than the pipe leading from the automatically
acting water cistern. In the top of the closed tank two air valves are provided
one of which opens inwards to afford free communication between the interior of
the tank and the atmosphere whilst the other opens or lifts upwards into a
connecting tube extending between the closed tank and a compressed air
receiver from the top of which a branch furnished with a stop cock or valve
leads to the barrel or other vessel from which the beer or other liquid is to be
raised or forced. The air receiver is or may he furnished with a gauge to
indicate the air pressure and in some cases the air receiver may be dispensed
with the air tube from the enclo-ed tank leading direct to the barrel.
Whilst various forms of automatically acting water cisterns may be used or
combined with the other parts of my apparatus I prefer to employ an automatic
apparatus of improved construction and which consists of a cistern or vessel
having a bridge across the top and between which and a sleeve or footstep at the
bottom a central vertical spindle preferably of square cross section is held the said
pindle passing through a float which is capable of free vertical movement upon it.
In conjunction with the font there is provided a lever centred at a point between
its ends the end opposite to the float carrying a "sucker' or other valve which
when the apparatus is filling closes the upper end of the pipe leading to the bottom
of the enclosed tank or vessel. The other end of the lever which is weighted has a
cross knife edge against which a trigger centred on the lower part of the float acts.
Water is led into the cistern either continuously or intermittently and as its level
rises the trigger on the float raises the weighted end of the lever a certain distance
and then disengages from it so that the said end of the lever suddenly falling opens
the valve at the upper end of the pipe and permits of the discharge of the water
into the closed tank or vessel underneath before the sucker valve again shuts. The
area of the water entrance into this vessel being greater than that of the outlet the
water rises in the interior thereby compressing the contained air and forcing
it through the upwardly opening valve into the compressed air receiver or into the
barrel.

1, WILLIAM Ross, Junior, of 62 Saint Vincent Street Glasgow in the County
of Lanark, Engineer, 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 :-
This invention relates to improvements in apparatus for raising or forcing beer and
other liquids to the point of drawing off or discharge and as shewn by the figure
on the accompanying drawings the improved apparatus consists of an automatically
acting water cistern or tank A situated at a point higher than the point of
discharge and from the bottom of which a pipe B extends downwards to near the
bottom of an enclosed tank or vessel (at whose side near the bottom a tube D
leading to a drain is connected this tube being of lesser area than the pipe B leading
from the automatically acting water cistern A. At the top of the closed tank C,
two air valves are provided one of which (the valve E) opens inwards to afford
free communication between the interior of the tank and the atmosphere whilst the
other Fopens or lifts upwards into a connecting tube G extending between the
closed tank C and the barrel H or other vessel from which the beer or other
liquid is to be raised or forced through the pipe I. The air tube G may be
provided with a stop cock or valve and the barrel H furnished with a gauge
if desired to indicate the air pressure.
Whilst various forms of automatically acting water cisterns may be used or
combined with the other parts of my apparatus prefer to employ an automatic
apparatus of improved construction and which consists of a cistern or vessel A.
having a central vertical spindle J preferably of square cross section removably
connected to the bottom of it the said spindle passing through a float K which
is capable of free vertical movement upon it. In conjunction with the float there is
provided a lever 1. centred at M the end of the lever farthest away from the
Hoat carrying a "sucker" or other valve N which when the apparatus is filling
closes the upper end of the pipe B leading to the bottom of the enclosed tank or
vessel (. The other end of the lever L which is weighted has a cross knife
edge against which a trigger y centred on the lower part of the float acts. Water is
led into the cistern either continuously or intermittently through the pipe O and as
its level rises the trigger y on the float raises the weighted end of the lever La
certain distance and then disengages from it so that the said end of the lever
suddenly falling opens the valve N and permits of the discharge of the water into
the closed tank or vessel C underneath before the sucker valve again shuts. The
area of the pipe B being greater than that of the outlet D the water rises in the
interior of the tank (thereby compressing the contained air and forcing it through
the upwardly opening valve into the barrel.
To provide for overflow from the cistern a small tube of equal area with the
outlet D from the tank is connected to the upper part of the cistern and led into
an upward extension of the pipe B.
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 1
claim is
1. The arrangement and combination of parts constituting the improved
apparatus for raising or foreing beer or other liquids and consisting of an
automatically acting water cistern A connected to a closed tank C having inwardly
and outwardly opening valves the latter being connected by a tube to the barrel
and the water connection between the cistern and the tank being of greater area

page_text: than the water outlet from the tank substantially as described with reference to the
accompanying drawings.
2. In apparatus of the class set forth an automatically acting water cistern
having its parts combined substantially as described with reference to the annexed
drawings.
