Improvements in and relating to Apparatus for Drawing off Beer
and other Alcoholic Liquids.
I, CHARLES HUELSER of the firm of Huelser & Co., of Temple Chambers,
London, International Patent Agency, do hereby declare the nature of this
invention a communication to me from abroad by the firm of Gebrüder
Guttsmann of Breslau in the Empire of Germany, Manufacturers, to be as follows:-
The object of this invention is an apparatus by means of which beer or other
alcoholic liquids can be drawn under high pressure from casks or receptacles,
which are capable of resisting only low pressure, without placing the latter under
high pressure.
The improved apparatus is in the main constructed as follows:
Two wrought iron receptacles are mounted on a common base plate. On a fixed
shaft provided on a carriage are secured the plugs of two three-way cocks, while
the body of each cock communicates through knee pipes with each of the two
receptacles mentioned above which are so mounted on the fixed shaft that they can
be tilted over from one side to the other whereby the bodies of the cocks are
caused to turn about the stationary plugs.
To relieve the cocks of the weight of the receptacles, the latter are supported
by arms revoluble about the fixed shaft. Each of the receptacles is at the top in
such connection with a four-way cock, that alternately either of the receptacles
can be made to communicate with the air pressure-inlet duct while the other
receptacle communicates with the air-pressure outlet duct. The four-way cock
is reversed by a pin provided on the plug lever moving, when the receptacles are
tilted to the other side, in a horizontal slot of an upright post rigidly secured on
the carriage. Near the carriage is placed an air-vessel with air-pump, which vessel
carries on top a pressure regulator which can be adjusted to any suitable pressure.
One tube or hose connected with the regulator conducts the full pressure of the air
vessel to the four-way cock and another tube leads the reduced pressure to the
cask or receptacle from which the liquid is to be drawn. Another tube connecting
the four-way cock with the air pump serves for pumping the utilized air contained
in the two receptacles back to the air vessel. One of the cocks with stationary plugs
is connected with the inlet sleeve for the liquid coming from the store cask or
reservoir, while the other of these cocks is connected with the sleeve leading to
the filter.
When one of the two receptacles is filled with the respective liquid, the apparatus
is tilted over to one side by the preponderance of the filled receptacle. The latter
is thereby caused to communicate with the outlet sleeve to the fitter and also with the
air pressure inlet tube; the liquid is thereby pressed from the receptacle to the
filter. The other receptacle is at the same time connected with the inlet tube from
the cask or store reservoir and with the tube for conducting the air to the air pump,
so that the liquid can be filled into this receptacle from the cask or reservoir.
When one receptacle is emptied and the other filled, the apparatus assumes the
opposite position so that the receptacle now filled can be emptied to the filter and
the other filled from the store cask. Thus a constant discharge to the filter is
attained and the required reversing of the cocks is effected automatically by the
apparatus.
To prevent the liquid from entering the air passages, a float ball is arranged in a
widening of each of the pipes connecting the two receptacles with the four-way
cock. The ball is lifted by the liquid and closes the air passage. Over the inlet
of each of the three-way cocks at the bottom of the receptacles a ball valve is

page_text: provided for the purpose of 'obviating a reaction, immediately after the apparatus
has been reversed, of the air pressure contained in the receptacles.
In a modified form of the apparatus the two receptacles are connected with and
bear on the two shells or bearing plates of a scale. They receive their movement
through two beams arranged as a parallelogram hinge fashion with the two supports
of the bearing plates. The shafts of said beams are lodged in stands provided on
the carriage. By the alternate ascent and descent of the two receptacles a four-
way air cock provided above and a three-way cock for the outlet of the liquid
provided below the receptacles are so regulated, that at the low position of one
receptacle compressed air enters the same from an air cliannel and presses the
liquid out of the receptacle while a valve provided in the bottom of the latter
remains closed by the higher tension of the compressed air. At the same time the
outlet opening of the other receptacle is closed by the three-way cock, the liquid
passes from the store cask into the receptacle through the valve provided at the
bottom thereof, expels the air, which passes through the four-way cock into the
outlet pipe and is blown with slight pressure through a reduction valve into
the atmosphere.
The same process is repeated in inverse order when the last mentioned receptacle
descends below the other receptacle.
The lower of the two beams mentioned above has an elongation with which it.
strikes against two superposed projections connected by a link and pivoted on a
stand. These projections are charged by a poise provided on the rearward
extension of one of them. By displacing the poise, the play of the beams can be
limited according to requirement. The elongated beam. is connected with an air
brake having a regulating cock and serving to diminish the increase of speed by
the action of overweight. Within the receptacles, valves are provided which close
the air openings of the receptacles when filled with liquid.. With each of the two
receptacles is connected a manometer for ascertaining the air pressure and a gauge
for ascertaining the level of the liquid.

Improvements in and relating to Apparatus for Drawing off Beer
and other Alcoholic Liquids.
í, CHARLES HUELSER of the firm of Huelser & Co. of Temple Chambers,
London, International Patent Agency, do hereby declare the nature of this
invention, a communication to me from abroad by the firm of Gebrüder
Guttsmann of Breslau in the Empire of Germany, 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 apparatus, by means of which beer or other alcoholic
liquids can be drawn under high pressure from large casks or other receptacles
which are capable of resisting only low pressure.
Referring to the accompanying drawing,.
Fig. 1. is a lateral view,
Fig. 2 a front view,
Figs. 3, 4 and 5 are details of the improved apparatus.
Fig. 6 is a side view and
Fig. 7 a horizontal section of a modification.
In Figs. 1 to 5, A, A¹ represent two wrought iron receptacles, which are mounted
on a common plate D. On a carriage C are mounted the bearings for a fixed
shaft w.
To this shaft are secured the plugs of three-way cocks a and b... The
bodies of these cocks are connected by knee-pieces y with the interior of the

page_text: receptacles A and A', so that when, the latter are tilted about the fixed shaft w,
the bodies of the cocks turn about the fixed plugs.
For the purpose of relieving the cocks, the receptacles A. A' are supported.on
the shaft w by arms e turning loosely about the latter. Furthermore, each of the
two receptacles A and A' is in connection with a four-way cock v, in such a
manner, that receptacle A can be connected with the, air-inlet duct and at the same
time A with the air-outlet duct,, and vice versa.
The four-way cock v is reversed by a pin of the cock-lever abutting (when the
apparatus is being tilted) against the sides of a slot formed on the stand which is
fixed on the carriage C. B is an air vessel with air pump, said. vessel carrying a
reducing valve adapted to be adjusted to any suitable. pressure. The tube or hose s
leads the full pressure obtaining in the air vessel to the four-way cock e, while
hose s conducts the pressure reduced at will, for instance to atmosphere, to the
store cask (not shown). Through tube the air which has been used in the
receptacles A or A' is pumped back into the air vessel. Figs. 3, 4 and 5 represent
cross sections of the three cocks in a position corresponding to the position of the
apparatus in Fig. 1. Cock a is connected with the inlet tube e for the liquid
coming from the store cask or reservoir, and cock 6 with the outlet tube i leading
to an ordinary beer filter (not shown).
In the position of the apparatus, shewn by Fig. 1, receptacle A has filled with liquid
and brought the apparatus by its over-weight into the position shewn. Thereby, as
may be seen from the cross-sections of the cocks, Figs. 3, 4 and 5, receptacle A is
connected with the outlet tube leading to the filter (through which the beer
passes to the retailing tap) and also with the air pressure inlet tube s.
The liquid
therefore is pressed out of the receptacle A and into the filter. At the same time
receptacle A is connected with the inlet tube e coming from the store cask and
likewise with the air-outlet tube leading to the air pump. Beer or other liquid
may therefore flow from the store cask into A¹. When A is pressed empty and A
filled, the apparatus assumes the opposite position of that shewn in Fig. 1, and A'
can be emptied towards the filter, while then A. fills from the store cask.
By the
described construction therefore a continuous outflow to the filter is attained, the
apparatus effecting the requisite reversal of the cocks automatically.
To prevent liquid from entering the air ducts, float balls y are arranged, which
are raised by the liquid, thereby closing the air passages. A reaction of the air
pressure existing in receptacles A and A¹ upon the store cask, immediately after
the reversal of the apparatus, is prevented by the ball valves (Fig. 1).
In the modification, represented by Figs. 6 and 7, the receptacles A and A' are
connected with bearing plates 12 arranged like scale pans and receive or transmit
motion through balance levers or beams c¹ c² forming part of a parallelogram,
and the shafts d' d² of which are lodged in stands e¹ e. By the alternate ascending
and descending of the receptacles A and A', the four-way cock v is so regulated for
air and the three way cock w for liquid, that, at the low position of receptacle A,
compressed air flows from duct into receptacle A. and presses the beer through
the outlet opening into the discharge tube, while the valve provided in the
bottom of receptacle A, remains closed by the greater tension of the com-
pressed air.
At the same time the outlet opening in the receptacle A¹ is closed by the
three-way cock w¹. The liquid coming from the store cask enters the receptacle A¹
through a valve in the bottom of the latter and displaces the air contained
therein, which arrives through the four-way cock in the outlet duct n and escapes
with slight pressure through a reducing valve into the atmosphere.
This process is repeated in the inverse order, when receptacle A' is in a lower
position, than receptacle A.
The lower beam c' abuts, at the ends of its stroke, against one or other of two
buffers or projections p', p² which are suspended in boxes moveable about the
pivots g and 9. The projecting buffers pl p² are wedge-shaped at their abutting
ends, the remainder sliding within the said boxes, which contain spiral springs, each

page_text: spring resting with one end against the bottom of the spring box and with the other
against a loose collar which has an arm projecting radially through a slot of the
spring box and abutting against the fixed stand which supports the brake
cylinder S. The buffers are connected together by a curved link, and both acted
upon by an adjustable poise r, acting against the spiral springs. By relatively
adjusting the poise, the free play or stroke of the scale beams c¹ and c³ can be
limited or increased by the position of the buffers p' and p² relatively to the end of
the beam c², according to requirements. The air brake ³, with regulating cock t,
serves to retard the motion produced by the difference between the weights of
receptacle A and A'. Within the receptacles suitable valves are provided, which
-close the air apertures of the receptacles, when filled with liquid.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1) In an apparatus for drawing beer and other alcoholic liquids under high
pressure from receptacles capable of resisting only low pressure, the combination
of the tilting receptacles A A¹, with the axle w, the three-way cocks a and b and
the four-way cock v, substantially as and for the purpose described.
2) The combination of the receptacles A A ascending and descending
alternately upon the plates 62 carried by the beams c¹² of a parallelogram, with the
three-way cock w' and the four-way cock v, as and for the purpose set forth.
