I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.L.M.E., of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street, Manchester, both in
the County of Lancaster, and 323 High Holborn, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object an air compressor for pumping up beer or for
other use, actuated by water pressure.
It consists essentially of the following parts:
The hollow body of the pump preferably made of thin metal, a receiver super-
imposed thereon for containing and transmitting the air compressed in the said body
and composed of a hollow chamber or inain part, an orifice which is normally closed
against internal pressure by means of a ciack valve actuated by a weight and having
a manometer destined to give a constant air pressure, a pedestal upon which is
mounted the pump body, a union to which may be attached the feed pipe for the
water, an air combined admission and escapement tube, a valve for governing the air
tube leading into the body of the pump, a float moving in a regulating container and
governing the waste water exit. This container is a sort of inner chamber com-
municating with the pump body by means of a small orifice in its bottom, which is
slightly raised, an emptying float regulating the air suction valve above mentioned, a
union tap for the pipe, conveying the compressed air to the beer barrel or otherwise,
a chamber situated between the body of the pump and the clack valve above mentioned
and containing a small emergency Hoat.
An open work sole serving to support the emergency float and which receives
beneath, on an india rubber washer, the thrust of the empyting float when the pump
empties itself.
The mode of working the apparatus is as follows:
:-
Water is introduced by a pipe into the hollow body and rising therein compresses
the contained air, the air thus compressed passes through the apertures of the open
work sole, past the emergency float, raises the clack valve when the pressure is
sufficient to do that, and its admission into the receiver is thus regulated by the
weight on the clack valve.
From this receiver, the air may be directed by a tube fixed to the joint tap
either into the beer casks or for any other purpose for which it is desired to
utilize it.
It must be noted that during the whole duration of the compression of the air in
the body of the pump, the water exit valve is kept pressed down on its seat by the
pressure of the compressed air in the body of the pump.
The water introduced into the pump body continuing to ascend, meets the emptying
float and raises it, in consequence of the movement of this float the air tube valve is
raised and the compressed air in the body of the pump escapes by the said air tube;
at this moment the equilibrium of pressure being destroyed the clack valve closes and
the water exit valve lifts, thus permitting the water contained in the body of the pump
to escape.
To insure the complete passing away of the water and in order at the same time to
prevent the water exit valve from falling back into its socket too suddenly, the
arrangement of the receiver is to be noted, which always maintains the float on the
water when the pump empties itself by reason of the slow emptying of the receiver.

page_text: In this manner, the exit float, being supported by the shank of the larger float,
remains raised, and in consequence keeps the exit valve up; suction of air is
produced thereby during the whole escape of water from the body of the pump by
the water exit opening, and also from the regulating chamber itself by the small
hole.
Another advantage of this regulating chamber is to modify the fall of the large.
float and consequently of the water exit valve as may be easily understood.
It is necessary to prevent water entering the compressed air receiving chamber
and consequently into the beer casks, in case, by reason of any accident, the valve
did not work and the water should fill the body of the pump and raise the clack
valve.
In order to prevent this mishap, the emergency float above mentioned is arranged
in such a manner that it may be raised by the water and closes the opening beneath
the clack valve.
All penetration of the water is thus avoided.
It
This apparatus being elegant and not bulky, and not requiring a special water
supply, can be made to represent a barrel, or Cambrinus or a Bacchante etcetera.
can be easily placed in a shop either on the counter, sideboard or elsewhere.

COMPLETE SPECIFICATION.
Improvements in Air-compressing Apparatus, Applicable to Raising
Beer or the like.
A communication from abroad by Messrs. JAY and JALLIFIER, 19, Avenue Thiers,
Grenoble, in the Republic of France, Builders.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, and 323, High Holborn in the County of Middlesex,
Civil 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 has for its object an air compressor for pumping up beer or for other
use, actuated by water pressure.
The annexed drawing represents in section an elevation of this apparatus in which
the following letters designate the various parts
A the body of the pump.
B, a receiver superimposed thereon, for containing and transmitting the compressed
air; it is composed of a hollow chamber or main part B, a clack valve R, a weight O
for actuating this valve, and a manometer M destined to give a constant air
pressure.
C, a pedestal upon which is mounted the pump body.
D, a union for the feed water pipe.
E, a combined air admission and exhaust tube.
F, a valve for admitting air into the body of the pump.
G, a float moving in a regulating container H.
H, a regulating container.
I, a valve actuated by the float G.
J, a float, actuating the air admission valve F.
K, a union tap for the pipe conveying the compressed air.
L, an aperture for emptying the water from the regulating chamber H.
S, a chamber situated between the body of the pump and the valve R adapted to
contain the float N.
N, a float adapted when raised to close the aperture of the valve R.

page_text: n² a perforated plate or grid serving to support the float N and which receives
heneath on an india rubber washer the thrust of the float J when the pump empties
itself.
The mode of working the apparatus as follows:-
Water is introduced through the pipe D into the hollow body A. and rising therein
compresses the contained air, the air thus compressed passes through the apertures
in n between the emergency float N and the sides of the chamber S, raises the clack
valve R when the pressure is sufficient to do that, and its admission into the receiver B
is thus regulated by the weight O on the clack valve.
From this receiver B, the air may be directed by a tube fixed to the union tap K
either into beer casks or other receptacle according to the purpose for which it is
desired to utilize it.
It must be noted that during the whole duration of the compression of the air in
the body A of the pump, the water exit valve I is kept pressed down on its seat.by
the pressure of the compressed air in the body A of the pump.
.
The water introduced into the pump body A continuing to ascend, eventually lifts
the float J in consequence of the movement of this float J, the air tube valve F is
raised and the compressed air in the body A of the pump escapes by the said air
tube E. At this moment the equilibrium of pressure being destroyed the clack
valve R closes and the water exit valve I lifts, thus permitting the water contained in
the body of the pump A to escape. Thus the moment the pressure ceases the
valve R closes, the valve F opens, and also the valve I and the floats G and J are
raised.
"
To insure the complete passing away of the water and in order at the same time to
prevent the water exit valve I from falling back onto its seat too suddenly, the
arrangement of the receiver is to be noted, which always maintains the float G on
the water when the apparatus is emptying itself by reason of the slow emptying of
the receiver. In this manner, the exit float J, being supported by the shank
g on the
larger float G, remains raised, and in consequence keeps the exit valve F raised; air
suction is thereby obtained while the water is passing away from the body of the
pump through the water exit opening I and also through the regulating chamber H
itself by the small hole L.
Another advantage of this regulating chamber is to allow the float G and
consequently the water exit valve I to descend gradually as may be easily
understood.
It is necessary to prevent water entering the compressed air receiving chamber B
and consequently into the beer casks, lest in the case of any accident the valve F
does not work and the water should fill the body of the pump and raise the clack
valve R.
In order to prevent this mishap, the emergency float N above mentioned is arranged
in such a manner that it may be raised by the water and close the opening beneath
the clack valve R.
The admission of water is thus avoided. It must also be noted that the admission of
compressed air into the receiver B is prevented by the weight O placed on the
valve R.
This apparatus being elegant and not bulky, and not requiring a special water
supply, can be made to represent a barrel, a Cambrinus or a Bacchante, etcetera.
can be easily placed in a shop either on the counter, sideboard or elsewhere.
It
Certain modifications may be made in the design and general arrangement of the
parts of the apparatus without departing from the nature of the invention herein
described and shown in the drawings.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
In an air compressing apparatus for raising or pumping up beer or other liquids
actuated by the pressure of water.
