page_text: LETTERS PATENT to Thomas Suffield of 150 Leadenhall Street in the City
of London, Hydraulic and Sanitary Engineer for an Invention of IMPROVE-
MENTS CONNECTED WITH HYDRANTS USED FOR WATER, GAS, AND OTHER
LIQUIDS AND FLUIDS
.
PROVISIONAL SPECIFICATION left by the said Thomas Suffield at the
Office of the Commissioners of Patents on the 10th February 1883.
THOMAS SUFFIELD of 150 Leadenhall Street in the City of London, Hydraulic
and Sanitary Engineer IMPROVEMENTS CONNECTED WITH HYDRANTS USED FOR
WATER, GAS, AND OTHER LIQUIDS AND FLUIDS
This Invention relates to the construction of Hydrants to be used as stop cocks
or valves for water or gas or other liquids and fluids where the flow is under
control, such Hydrants being applicable for the varied requirements on board
steam or sailing ships or vessels, fire and other mains, in towns, mansions,
manufactories, breweries, tanneries, and especially in theatres, large or small
buildings, baths, etc.
The Hydrant may be made from various metals, such as cast iron, Phosphor
bronze, brass, gun metal, vulcanite; or a combination of metals, or of any other
mixture or compound that will resist the action of chemicals, acids, or liquids.
The first improvement consists of a sheathe, cylinder, metal liner, to be inserted
in the upper part of the body or chamber of the Hydrant and of the Hydrant'
itself either with or without such sheathe, cylinder, or metal liner to receive a
cupped leather or other material capable of resisting the action of hot or cold water
or other liquid, such cup to be fixed on the valve spindle or frame of the valve, or
on the under side of the Hydrant cover or in such place and form as will act in the
place of a gland or stuffing box to the said Hydrant and may be removed with the
cover, spindle, and valve when required.
The second improvement consists of a washer or a number of washers stamped,
compressed, or otherwise formed hollow shape to be used in the construction and
formation of the said Hydrant.
The third improvement consists of a frost valve or cock arranged in the body of
the Hydrant at the lower part, said valve being kept open by the action of a spring
and capable of being closed by a lever connected to the main valve spindle when
said spindle is raised to open the passage,

by the said Thomas Suffield in the Great Seal Patent Office on the
10th August 1883.
THOMAS SUFFIELD of 150 Leadenhall Street in the City of London IMPROVE-
MENTS CONNECTED WITH. HYDRANTS USED FOR WATER, GAS AND OTHER LIQUIDS
AND FLUIDS
This invention relates to the construction of hydrants to be used as stop cocks
or valves for water or gas or other liquids and fluids where the flow is under
control Such hydrants being applicable for the varied requirements on board
steam or sailing ships or vessels fire and other mains in towns mansions manu-
factories breweries tanneries and especially in Theatres large or small buildings
baths etc
The hydrant may be made from various metals such as cast iron phosphor bronze,
brass, gun metal, vulcanite or a combination of metals or of any other mixture or
_ compound that will resist the action of chemicals acids or liquids.
The first improvement consists of a sheath, cylinder, metal liner inserted in the
upper part of the body or chamber of the hydrant and of the hydrant itself either
with or without such sheath, cylinder or metal liner to receive a cupped leather or
other material capable of resisting the action of hot or cold water or other liquid
such cup being fixed on the valve spindle or frame of the valve or on the under
side of the hydrant cover or in such place and form as will act in the place of a
gland or stuffing box to the said hydrant and may be removed with the cover
spindle and valve when required.
The second improvement consists of a washer or a number of washers stamped
compressed or otherwise formed hollow "shaped" and used in the construction and
formation of the said hydrant
The third improvement consists of a frost valve or cock arranged in the body of
the hydrant at the lower part said valve being kept open by the action of a spring
and capable of being closed by a lever connected to the main valve spindle when
said spindle is raised to open the passage.
My invention will be clearly understood by the annexed drawings in which in
Figure 1 my sheath or liner a in cylindrical form is fitted within the body b of the
hydrant for the cupped leather or other hollowed washer c of semicircular; shape
to bear against and preserve the upper part of the hydrant in a water tight
manner the shape of the cupped leather c being kept intact by the internal cup d
on the spindle e which is screw threaded and works in the threaded gland f of the
top cap g. h is the water valve also of cupped leather or other material shaped to
correspond and to sit upon the seating i to close the passage through from the
main or service connection ; to the outlet k on which a cap can be arranged in the
usual manner. The two cupped leathers in this arrangement are in the same
order or direction but in Figure 2 in which the liner cylinder is dispensed with
the two cupped leathers c are reversed.
Figure 3 shows a hydrant in section in which the upper cupped leather c
is flat in its body and held between the disc and a ring m by bolts or screws the
lip n only bearing against the body of the hydrant or against the liner cylinder
if one be fitted therein to make the upper part liquid tight The lower or liquid
valve h is of rounded cupped form but any other shape may be adopted to close the
passage from the main or service to the outlet.
In Figures 4 and 5 I have shown my frost valve or cock as part of or connected
to the body of the hydrant the passage through which is opened and kept open
for the escape of liquid that may be left in the branch k and body b after the

page_text: valve h is closed whereby the passage is always clear and the valve h readily lifted
from its seat which is so shaped that no grit or foreign substance can lodge itself
to prevent a perfect closing of the valve thereon. In the last two mentioned
figures and also in Figure 6 I have shown three hydrants as terminals to a single
main or service but any number of hydrants can be arranged as desired.
In Figure 5 I have shown a connection p to the main or service so that the
hydrants instead of serving as terminals are arranged as intermediates. The frost
or relief valve is provided with a spring u or a weight, to keep it closed when the
hydrant is open the rod q of the small valves being governed by the lever r the
end s of which projects under the flange. t of the hydrant screw stem
Having thus described the nature of my said invention and in what manner the
same is to be performed I declare that I claim.
First. The construction or arrangement of hydrant in which a clear passage for
the liquid or fluid from the main or service to the outlet is established as
described and as shown in the annexed drawings
Secondly I claim The inner cylindrical liner in combination with two cupped
leathers or equivalents shaped valves on the same stem-one valve to
shut off the liquid from the gland or upper part and the other to sit
upon a seating in or on which no grit or foreign substance can rest that
would prevent the proper closing thereof as described and as shown in
the annexed drawings
Thirdly I claim the construction arrangement or method of the relief valve for
emptying a hydrant after the main valve is closed as and for the purposes
set forth
In witness whereof I the said Thomas Suffield have hereunto set my hand
and seal this eighth day of August in the year of our Lord One thousand eight
hundred and eighty three.
