We, ROBERT HENDERSON, Wine and Spirit Merchant of 110 Bellgrove Street,
Glasgow, Lanarkshire, and WILLIAM FLEMING, Plumber and Gasfitter of 269 Duke
Street, Glasgow aforesaid, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved apparatus for raising or forcing beer or other
liquid and it has for its object to so construct such apparatus that whilst having fewer
working parts, as compared with apparatus of this class heretofore in use, an equal if
not greater efficiency in the working is obtained.
The apparatus as constructed under this invention consists of a closed metallic
tank or vessel, having at one part of the lid or upper side, a raised portion of dome
or other shape whereon is situated a valve chest from which a pipe communicates
with the barrel or other vessel containing the liquid to be forced or raised, air under
pressure being passed into the barrel or other vessel by the action of the apparatus
as hereinafter described.
To one of the sides of the tank there is fixed an inlet or water supply valve, com-
municating with the water main, cistern or other source of water supply by a pipe
secured to its outer extremity. This valve allows water to rise in the tank to a
predetermined point the water on reaching which point is cut off by the action of
a float. This float is free to rise and fall in the dome or raised part of the tank, and
has connected to its under side a vertically moving lever pivotted near its lower
extremity to a standard or pillar secured to the bottom of the tank. On this standard
another, vertically moving lever, weighted at its upper end, is centred at some distance
from its lower end and it has on it two pins or projections. This latter lever which
has its path at right angles to the before mentioned lever is free to move in a slot
made in a bar or rod, one end of which is connected to or forms part of the inlet
water supply valve and its other end is connected to an outlet valve placed at the
opposite side of the tank from the inlet valve, these valves being opened or closed by
the reciprocation of the lever working in the slotted bar.

page_text: The action of the apparatus is as follows:-Water is allowed to flow into the tank
or vessel through the inlet valve until the desired pressure is reached. The rising of
the water in the tank forces the air through the valve chest on the upper part thereof
and thence through the pipe connected to the barrel or other vessel containing the
liquid to be forced, at the same time the water raises the float, which on the water
reaching a certain level, acts on the lever connected to its under side, and causes the
lower end of said lever to move in a downward direction. The lever in so moving
comes in contact with one of the pins or projections on the weighted lever and throws
it over, this action causes the weighted lever to traverse the slot in the bar connecting
the valves whereby the outlet valve is opened and the water supply valve closed. The
water in the tank is now allowed to flow away and the flot sinks into position to
actuate the slotted bar in the opposite direction and so to again open communication
with the water supply. The air forced into the barrel or other vessel by the rising of
the water in the tank is prevented from returning by the valve in the chest on the
upper side of the tank. This valve also in case of breakage or derangement of any
of the working parts of the apparatus prevents water entering the pipe leading to the
barrel or other vessel and spoiling its contents, it also obviates the necessity of great
lengths of piping being required to effect this prevention. On the dome or raised
part there is also provided a valve opening inwards to supply air to the interior of
the tank as the water is exhausted therefrom.
Under a modification instead of opening and closing the inlet and outlet valves by
the weighted lever working in a slot in a bar connected to and working both valves,
the same action may be produced by a vertical lever connected at its upper end to
said weighted lever and fulcrumed at its lower end on a bracket formed on the inlet
valve. The spindle of the inlet valve and that of the outlet valve being connected,
at some distance apart, to this vertical lever. The weighted lever, which is provided
with stops or other arrangement to prevent its too great lateral movement on being
thrown over by the lever connected to the float, takes with it the vertical lever and so
opens and closes the valves. This arrangement allows the inlet valve to be placed
higher than the outlet valve or vice versa.

Improvements in Apparatus for Raising or Forcing Beer and other
Liquids.
We, ROBERT HENDERSON, Wine and Spirit Merchant of 110 Bellgrove Street
Glasgow, Lanarkshire and WILLIAM FLEMING Plumber and Gasfitter of 269 Duke
Street Glasgow, aforesaid, 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 an improved apparatus for raising or forcing beer or other
liquid and it has for its object to so construct such apparatus that whilst having fewer
working parts as compared with apparatus of this class heretofore in use, an equal if
not greater efficiency in the working is obtained.
As shown on the accompanying drawings, fig. 1 of which is a side elevation fig. 2,
an end elevation, fig. 3 a plan fig. 4, an end elevation of the modification of the
invention and fig. a detail, shown in section, our improved apparatus consists of a
closed metallic tank or vessel A, having at one part of the lid or upper side a raised
portion of dome or other shape B, whereon is situated a valve chest C, from which a
pipe communicates with the barrel or other vessel containing the liquid to be forced
or raised, air under pressure being passed into the barrel or other vessel by the action
of the apparatus, as hereinafter described.
To one of the sides of the tank A, there is fixed an inlet or water supply valve D,
which may be of any convenient form but is preferably a Lambert valve' as shown
more particularly at fig. 5, communicating with the water main, cistern or other source
of water supply. This valve on being opened allows water to rise in the tank to a
predetermined point, on reaching which the water supply is cut off by the action of a
float E. This float is free to rise and fall in the tank and it has connected to it a
vertically moving lever F, pivotted at F to a standard or pillar G, secured to the
bottom of the tank. Centred at G¹ on a pin fixed in this standard is another verti-
cally moving lever or 'kicker 'H, weighted at its upper end H¹, and which has on it
two projections or pins I, I'. These projections may if desired be made so as to form
a curve as seen at 1' fig. 2. The lever H, has its path at right angles to the lever F,
and is free to move in a slotted bar J (or a bar having a projecting part at each end
may be used) one end of which is connected to the inlet water supply valve D, by a
link K, and its other end is connected to the outlet valve L by a link M. These
valves D, L as seen more particularly at fig. 5, are opened and closed by the recipro-
cation of the links K, M, the links being made to work in slots O, made in the
plunger O', of the valves and so open and close them, and in order that the valve D,
may be opened when the valve L is closed and vice versa, the link K, is fulcrumed
on a lug P, formed on the under side of the valve D, whilst the link M, is fulcrumed
on a lug Pi formed on the upper side of the valve L. By this means a
effective action of the valves is secured.
simple and

page_text: The action of the apparatus is as follows:-Water is allowed to flow into the
tank or vessel through the inlet valve D, which when working from a cistern is con-
nected direct to the source of water supply but when working from the main on
account of the great water pressure it is found advantageous to use a pressure
reducing valve Q, figs. 1, 2 and 3 hereinafter described. The rising of the water in
the tank forces the air through the valve R, on the upper part thereof and thence
through the pipe connected to the barrel or other vessel containing the liquid to be
forced, at the same time the water raises the float E which on the water reaching a
certain level acts on the lever F, connected to it and causes the other end of said
lever to move in a downward direction. The lever F in so moving comes in contact
with the pin or projection I on the weighted lever or 'kicker" H, and throws it
over, this action causes the weighted lever H, to traverse the slot in the bar J, and
strike the opposite end of the slot with sufficient force as to reciprocate the
links K, M, and so open the outlet valve L and close the inlet valve D. The water
in the tank A, is now allowed to flow away and the float E sinks into position to
actuate the slotted bar J, in the opposite direction by striking the projection I' and
thereby again open communication with the water supply. The air forced into the
barrel or other vessel by the rising of the water in the tank is prevented from
returning by the valve R, in the chest C, on the upper side of the tank. This valve
also in case of breakage or derangement of any of the working parts of the apparatus
prevents water (through the action of a. small float T, attached to its under side,
rising and closing the valve R) entering the pipe leading to the barrel or other vessel
and spoiling its contents it also obviates the necessity of great lengths of piping being
required to effect this prevention. On the dome B, there is also provided a valve U,
opening inwards to supply air to the interior of the tank as the water is exhausted
therefrom.
It is found advantageous when working our improved apparatus from the main, to
have a pressure reducing valve such as shown at Q, figs. 1, 2, and 3 of the drawings.
This valve which may be a 'Lambert' valve as shown, communicates with the main
by means of a pipe connection V, and by a short pipe W and screwed connection W'
with the water inlet valve D. The valve Q is actuated by means of a small ball or
other float X, connected by a lever Y with the plunger Z of the valve. The rise and
fall of the float X and consequent opening and shutting of the valve Q is regulated
by the adjustment of a weight a, hung on a graduated lever b, centred at c, to a
bracket d, formed on a tubular casing e, on top of the small dome f, secured to the
top of the tank. The graduated lever b, bears on its under side on a short spindle g,
free to move in the casing e. The lower end of the spindle y bears on the top of an
india-rubber cup h, contained within the dome f. A spindle i connected at its lower
end to the lever Y and having a knob j bearing on the inside of the cup h, allows
the float X, to rise or fall, and so open or close the valve Q, according to the expan-
sion or contraction of the india rubber cup. As shown at figs. 1, 2 and 3 the pressure
reducing valve is allowing water to enter the valve D and so into the tank. The
weight a being shifted along the lever b, to a point indicating the pressure of air
required, its tendency is to press down or collapse the cup h, and thus keep the
valve Q open; but when the desired pressure of air is exceeded, the air forces up or
expands the cup h and so allows the float X to rise and cut off the water supply
through the valve Q..
Under a modification as seen at fig. 4, instead of opening and closing the inlet
valve D (which in this case communicates direct with the water supply without the
intervention of a pressure reducing valve) and the outlet valve L, by the weighted
lever H, working in a slotted bar connected to and working both valves, the same
action may be produced by a vertical lever L' having a slotted bar J, or a bar
having a projection at each end may be used, wherein works the weighted lever H,
connected to it at its upper end and fulcrumed at its lower end on a bracket k formed
on the inlet valve D. The spindle of the inlet valve D and that of the outlet
valve L being connected at and m respectively to the vertical lever L'. The
weighted lever or 'kicker' which may be provided with stops or other arrangement

page_text: to prevent its too great lateral movement, on being thrown over by the lever F,
connected to the float E strikes one end or projection of the bar J with sufficient
force to open and close the valves. Under this arrangement the inlet valve may be
placed higher than the outlet valve or vice versa. Valves of the construction shown
may be used or 'Lambert' or other suitable valves may be employed.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. In an engine for raising or forcing beer or other liquid, the use of a weighted
lever or 'kicker H, having on it two projections 1, I substantially as and for the
purposes set forth.
2. In an engine for raising or forcing beer or other liquid the opening and closing
of the inlet and outlet valves by means of links reciprocated by the action of a
weighted lever or 'kicker,' having on it two projections, striking the ends of a slotted
bar (or of a bar having a projection at each end) to which said links are pinned
substantially as described and shown on the drawings annexed.
3. In an engine for raising or forcing beer or other liquid the use of a float
attached to the under-side of the air outlet valve for the purpose of preventing water
entering the pipe leading to the barrel or other vessel containing the liquid to be
forced.
4. In a beer or other liquid raising engine the combination of the weighted lever
or 'kicker' H, reciprocated by the action of a float, with the slotted bar J, and
links K, M, substantially as and for the purposes described.
5. In a beer or other liquid raising engine the combination of the lever H,
links K, M, and inlet and outlet valves D, L, with a pressure reducing valve acting
as described.
6. The combination in a beer or other liquid raising or forcing engine of the
lever H, bar J, and vertical lever L' substantially as described and shown on fig. 4
of the drawings annexed.
7. The general arrangement and combination of parts of our improved beer or
other liquid raising or forcing engine, substantially as described and shown on the
accompanying drawings.
