CHRISTOPHER THOMAS WORDSWORTH of Leeds in the County of York, Engineer,
and JOHN WOLSTENHOLME of Radcliffe, in the County of Lancaster, Engineer,
"IMPROVEMENTS IN THE METHOD OF RAISING AND FORCING ACIDS, CHEMICALS,
AND OTHER FLUIDs, and in the APPARATUS FOR Effecting the samE,"
This invention relates to Improvements in the method or system of forcing
Acids, Chemicals, or any other kind of liquids, such as, Beer, Milk, Spirits, &c. by
the action of Air, Gas, Steam or any other liquids acting upon the internal or
external body of an elastic bag or bladder, which may be constructed of india-
rubber or other suitable material, inside a vessel or casing. The object is to
dispense with diaphragms, pistons, or any working parts liable to leakage or
deterioration, and in cases where necessary has a higher degree of refrigerating power
upon milk or perishable liquids. The same system may be utilised as a medium
for imparting a suitable temperature to any liquid it may be desirable to operate
upon. For conciseness and brevity water shall be hereinafter referred, to, and,
understood as, the motive power in this Specification. 1st. The first part of our
improvements consists in having a Casing or Vessel, or any number of them, such
herein after, being referred to in the singular, to be made of suitable material,
preferably iron or earthenware, erected upon a bed plate or framing, such vessel
may have any suitable form, but spherical is preferred, with an extension or foot
piece, through which is an aperture large enough to insert or pass through the
contracted body of an elastic bag or bladder, the external shape of which, when

page_text: not under pressure, approximately fits the inside shape of the vessel. This elastio
bladder has a strong extension or neck, and an orifice through the neck, with a
suitable flange which fits a corresponding recess formed between the joint or face
of the foot piece or bed plate. We insert a central tube or pipe connection
having a collar or flange attached into the inside body of the elastic bladder
through the orifice, but made sufficiently tight as to resist all leakage from one
side to the other. The said central pipe is branched to á valve chamber having
suitable valves therein, and in direct communication with the liquid, which runs in
by gravitation, that is required to be forced to any other part of the building. The
Vessel or Casing is provided with a port or passage suitably placed to allow the
ingress or egress of the water close to and in connection with which is placed a
cock or valve with suitable ports or passages, and for distinction is herein called
the transmitting Valve. Such transmitting valve is connected to a branch supply
pipe that may be placed in a horizontal position, and in a line with the bed plate.
On the main supply pipe is attached a Reducing Valve, to regulate the required
pressure for the discharge of the liquor. The said branch supply pipe may be of
sufficient length and in connection with, any number of vessels or casings, through
their respective transmitting valves, as may be required. The said branch supply
pipe is separated from the main supply pipe by a cock or valve, hereinafter called
the main inlet valve. Such main inlet valve is actuated by any well-known
mechanical means, such as levers, &c, and wires, that may be in direct cómmuni-
cation with any other room, landing, or other portion of a building, where it is
desirable to force the liquid. The main inlet valve may be actuated by the
well-known pneumatic system in hotels, steamships, &c., or by an electric apparatus,
suitably placed to save the wear and tear of the wire connections.
The transmitting valve when open to the branch supply pipe has a restricted

the branch supply; it opens the outlet port to the inside of the casing or vessel, and
allows the body of water that has accumulated in the inside of the casing by a
previous compression, to escape and thereby allow the bladder to refill. It will be
noticed that in one of its principal functions, that as the water from a previous
compression is rushing out by the outlet passage, the beer or liquid will be con-
siderably asssisted by, the action of atmospheric pressure to refill the elastic bag or
bladder. When the lever is moved so that the restricted opening is in line with
the branch supply, the outlet is shut. When the operator requires to force liquid
to any given portion, he first opens the transmitting valve to the branch supply by
the action of a lever, and assuming the elastic bag or bladder to be filled with beer
or other liquid. When the main inlet valve is opened, the pressure accumulates
inside of the casing and compresses the contents of the elastic bag or bladder
through the central pipe and valve chamber and up to the tap or any other desired
position, after the manner of a syringe. 2nd. This method gives a greater capacity
to refrigerating liquids,. if necessary, having nearly all its circumference immersed
with water.
.
This system can with advantage work by the inverse rule, viz: By taking in
.the liquid to be forced into the casing and the water would be conducted by a
suitable system of piping into the body of the bladder by an arrangement of valves
to suit the alteration.
3rd This arrangement is also applicable for the purpose of raising or elevating
chemicals in Bleachworks, by the foregoing method.

Great Seal Patent Office on the 23rd September 1882.
CHRISTOPHER THOMAS WORDSWORTH, of Leeds, in the County of York,
Engineer, and JOHN WOLSTENHOLME, of Radcliffe, in the County of Lancaster,
Engineer, "IMPROVEMENTS IN THE METHOD OF RAISING AND FORCING ACIDS,
CHEMICALS, AND OTHER FLUIDS, AND IN THE APPARATUS FOR EFFECTING. THE
SAME,"
This Indenture relates to Improvements in the method or system of forcing
Acids, Chemicals, or any other kind of liquids such as Beer Milk Spirits &c by the
action of Air Gas steam Water or any other fluids acting upon the internal or
external body of an elastic bag or bladder which may be constructed of india-
rubber or other suitable material inside a vessel or casing. The object is to
dispense with diaphragms pistons or any working parts liable to leakage or
deterioration and in cases where necessary our invention imparts a higher degree of
refrigerating power upon milk or porishable liquids. The same system may be
utilised as a medium for imparting a suitable temperature to any liquid it may be
desirable to operate upon.
For Conciseness and brevity, water shall be herein
after referred to, and understood as the motive power in this Specification
1st The first part of our improvements consists in having a casing or vessel or any
number of them, such hereinafter being referred to in the singular number to be
made of any suitable material, preferably iron or earthenware erected upon a
bedplate or framing such vessel may have any suitable form but the spherical
form is preferred with an extension or foot. piece through which is an aperture
large enough to insert a pass through the contracted body of an elastic bag or
bladder the external shape of which when not under pressure approximately fits
the inside of the vessel. This elastic bladder has a strong extension or neck and
an Orifice through the neck with a suitable flange which fits a corresponding
recess formed between the joint or face of the foot piece and the bedplate. Wo
insert a central tube or pipe connection having a collar or flange attached into the
inside body of the elastic bladder through the orifice but made sufliciently tight as
to resist all leakage from one side to the other. The said central pipe is branched
to a valve chamber having suitable valves therein and in direct communication
with the liquid (which runs in by gravitation) that is required to be forced to any
other part of the building-The vessel or casing is provided with a port or passage
suitably placed to allow the ingress or egress of the water
2nd. The second part of our Invention consists in the method of operating the
elastic bag or bladder by a system of valves to admit the inlet and outlet of water
to the vessel or casing. For this purpose we mount upon a plate or any suitable
table, a valve or tap suitably interposed between the main supply pipe and the
branch supply pipe. The said branch supply pipe being in connection with one or
more of the before mentioned casings. When the valve or tap is depressed by the
operator by means of the action of a lever it allows water to pass into the branch
supply pipe. On the same plate or table is suitably mounted a compound exhaust
valve which is depressed when the lever is in a neutral position; after first
shutting off the water inlet by the same lever, and allowing the surplus water
that may have accumulated in any of the casings to pass by way of the branch
supply pipe.
3rd. The third part of our Invention consists in having a casing suitably fitted
with a bag as before described which dispenses entirely with the use of water for
its motive power and instead thereof is actuated by mechanical means.
