PROVISIONAL SPECIFICATION.
Improved Apparatus for Drawing Beer and other Liquids.
I GEORGE WILSON LUNN of 21 Yorkshire Street Oldham in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows: :―
The object of this invention is to provide simple and efficient means for drawing
beer or other liquids at a hotel bar or similar place from barrels or casks in a cellar
without pumping the same by hand as is usual at present.
According to my invention I connect the pipe from the barrel or cask with a
cylinder by means of a suitable valve at one end thereof. This cylinder may be
made of aluminium, hard wood, vulcanite, or other suitable material to avoid the
formation of verdegris, and is by preference placed in a vertical position in the cellar
or in the bar.
At the other end of the cylinder is a gland or stuffing box, through which works
the shaft of a rotary propeller of suitable construction, and at or near this end of
the cylinder is an outlet communicating by a pipe with a vessel or receiver on the
bar counter provided with a tap or taps hereafter described.
The propeller shaft is driven by suitable toothed or friction gearing from a
horizontal shaft rotated by electricity, turbine, hand or other power; the driving
wheel on the said horizontal shaft is mounted so that it can slide thereon and move
into or out of gear with the wheel driving the propeller shaft, and it is moved by
means of a lever which can either be set in one position or the other by hand or by
means of an electro magnet controlled by a switch button conveniently situated in
the bar or other place where the beer or other liquid is required. Thus it will be
evident that the beer or liquid in the cask or barrel can be raised by the propeller
when required into the receiver.
I prefer to make the said receiver of glass and protect it by a brass or other
casing or frame, so that the supply can be seen, and as the receiver is large enough
to contain more than one glass-ful of beer or liquid the attendant can see whether
it is necessary to raise more beer &c. before turning his tap to fill his glass or
tankard therefrom. The receiver is also made with its lower end or bottom
inclined towards a tap or valve from which hops sediment and other impurities can
be withdrawn when required; it is also provided with a small vent or valve at the
top to relieve pressure.
I further propose to use a small float inside the receiver provided with a suitable
spindle or device whereby it can automatically complete an electric circuit when
the said receiver is empty or nearly empty, and so excite the electro magnet above
named to set the propeller shaft in motion and raise the liquid automatically when
required. Should the receiver become broken it can readily be replaced by
another, or by a plain hood provided with a withdrawal tap, and repaired.
The receiver may be made in other forms or shapes and of other materials if
preferred, and may be provided with an outer casing to contain ice or other
refrigerating material. Or a turbine can be employed instead of the propeller
above described.

GEORGE WILSON LUNN of 21 Yorkshire Street Oldham in the County of
Lancaster Engineer I 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:-
The object of this invention is to provide simple and efficient means for drawing
beer or other liquids at a bar or similar places from barrels or casks in a cellar
without pumping the same by hand as at present.
According to my invention I connect the pipe from the barrel or cask A Fig. 1
with a cylinder B with suitable valves at each end thereof. This cylinder and
valves may be made of aluminium vulcanite or other suitable material to avoid the
formation of verdegris and is placed in a vertical or horizontal position in the cellar
or in the bar. At the other end of the cylinder B is a gland or stuffing box
through which works the shaft D of a rotary propeller or piston rod of a pump of
suitable construction and at or near this end of the cylinder is an outlet communi-
cating with a pipe H with a vessel or receiver R Fig. 2 on the bar counter provided
with a tap T hereafter described.
The propeller or pump shaft is driven by suitable tooth or friction gearing F
Fig. 3 from an horizontal shaft M rotated by electricity turbine or hand power the
friction wheel F on the said lever L is mounted so that it can slide or move
horizontal or vertical into or out of gear with the wheel M driving the propeller or
pump shaft P it is moved by hand or electric moter controlled by a switch S Fig. 2
conveniently situated in the bar or other place where the beer or other liquids is
required thus it will be seen that when the electric current is switched on the
electric magnet E Fig. 3 acts on the lever L and draws it down bringing the
wheel F in contact with the wheel M which the moter turns and then turns
the wheel F and P which works the pump or propeller shaft thus it will be evident
that the beer or liquid in the cask or barrel can be raised by the propeller or pump
when required in the receiver R Fig. 2.
I prefer to make the receiver R Fig. 2 of glass and protect it by
a brass or
other casing or frame so that the supply can be seen and as the receiver is large
enough to contain more than one glass of beer or liquid the attendant can see
whether it is necessary to raise more beer before turning his tap to fill his glass or
tankard therefrom the receiver R is also made with its lower end or bottom inclined
towards a tap I or valve from which hops or sediments can be withdrawn when
required it is also provided with a small vent or valves V Fig. 2 at the top to
releive pressure in or outside the receiver R and the valves are covered with a metal
cap C.
a
Should the receiver R become broken it can readiley be replaced by another or by
plain hood provided with a withdrawal tap I untill repaired.
The receiver may be made in other forms or shapes and of other material if
prefered with an outer casing G made of glass or other materials to contain water
and ice or other refrigerating materials.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
1st. The appliance for working pumps or propeller shaft by electricity with
friction or tooth wheels and electric magnet as described above.
2nd. The use of receiver or vessels to hold the beer or liquid with or without an
outer casing as described above.
