CHARLES CASIMIR BARTON, of Rochester, New York, United States of America,
now of 8, Southampton Buildings, London. "AN IMPROVED FLUID PRESSURE
REGULATOR, CHIEFLY DESIGNED FOR MAINTAINING A DETERMINED AND UNIFORM
PRESSURE IN HOUSEHOLD AND OTHER WATER SUPPLY PIPES."
My Invention relates to an improved apparatus to be connected with the pipes
which supply water to houses, or with other pipes for conveying water or other
fluids under pressure from a main or otherwise.
This improved apparatus is chiefly designed as a regulator or controller of the
pressure in the water supply pipes, so that the pipes in any part of a house or
building supplied with water will not be exposed to excessive pressure, or to any
but very slight variations of pressure; and for the same purpose the said apparatus
may be applied to any of the mains or service pipes of the waterworks of a town
or city, its advantage being most apparent in cases where the water-has-to be
delivered to points or localities situated at greatly different levels or elevations.
In practising my Invention I provide a suitable case or box, which is to be con-
nected on one side with the supply pipe from the main, and on the other side with
the discharge or delivery pipes in the house or otherwise. Within the said case or
box I arrange a valve which is closed by the pressure in the outlet or delivery
pipe against the action of a controlling spring or weight. I prefer that the said
box should be formed in three pieces or parts; one of these parts is connected with
the supply and contains the valve and valve seat; another part is connected with
the discharge and is provided with a diaphragm of india rubber or other flexible
material; and the third part forms a cover placed over the said diaphragm.
I prefer to use a valve constructed in the form of a cylindrical weight, and
suspended by a sheet of india rubber or other suitable material interposed between

page_text: the said cylindrical weight and the seat in such a manner that when the valve
descends the said india rubber or other material makes a perfectly tight joint
between the valve and seat, and also allows the said valve to rise and descend with
the slightest possible friction.
An arm attached to the said valve projects through the orifice or aperture thereof,
and is connected with a rod or link which is jointed to a rod or spindle that passes
centrally through the said diaphragm, and is secured and made water tight therein
by nuts and washers or other suitable means. The said rod or spindle also passes
through the cover, and has its upper end arranged in contact with the aforesaid
controlling or regulating spring. This spring is carried by a bracket formed on or
attached to the said cover, and provided with an adjusting screw or other device
for regulating or varying the tension or pressure of the said spring; or in place of
a spring a weight may be used if found more convenient or desirable under any
particular circumstances; and a butterfly or other suitable form of valve may be
used if desired, although I prefer to use the valve above described in all cases where
it is desired to perfectly close the orifice of the same.
When this apparatus is properly connected with the supply and delivery pipes
the pressure to be permitted to exist in the delivery or discharge side of the valve
must be first determined, and the spring or weight must be adjusted or regulated
to this pressure. This adjustment or regulating having been effected it will not be
possible for the pressure in the delivery pipes to exceed the determined amount or
degree, whatever may be the pressure or variations of pressure in the main or other
pipes on the supply side of the valve. The slightest excess or preponderance of
pressure on the delivery side will overcome the resistance of the spring; the valve
will then close and will remain closed until by the opening of one of the cocks or
valves in or connected with the discharge pipe, or by leakage, the pressure in the
said pipe is reduced; the spring then opens the valve and allows sufficient water
to pass through the valve to restore the pressure in the discharge pipe, the said
valve then closing immediately. Thus it will be seen that the said apparatus is
very effectual for controlling or limiting the pressure in the pipes without obstructing
the supply of water.
My improved apparatus may be constructed of any required dimensions, and
used under all circumstances when it is desirable to control fluid pressure in the
manner above specified.

the said Charles Casimir Barton in the Great Seal Patent Office on the 10th
September 1880.
CHARLES CASIMIR BARTON, of Rochester, New York, United States of America,
now of 8, Southampton Buildings, London. "AN IMPROVED FLUID PRESSURE
REGULATOR, CHIEFLY DESIGNED FOR MAINTAINING A DETERMINED AND UNIFORM
PRESSURE IN HOUSEHOLD AND OTHER WATER SUPPLY PIPES."
My Invention relates to an improved apparatus to be connected with pipes which
supply water to houses, or with other pipes for conveying and delivering water or
other fluids under pressure.
This improved apparatus is chiefly designed to so regulate or control the pressure
in water-supply pipes that the pipes in any part of a house or building supplied
with water thereby will not be exposed to excessive pressure, and the variations of
pressure will be very, slight; and for the same purpose the said apparatus may be
applied to any of the mains or service pipes of the water-works of a town or city,
its advantage being most apparent in cases where the water has to be conducted
and delivered to buildings or localities situated at greatly different levels or
elevations.
My Invention is illustrated in the accompanying Drawing, in which,-
Figure 1 is a central vertical section of my improved fluid pressure regulator
shewing the valve open.
Figure 1 is a similar section of a portion of the said regulator shewing the valve
closed.
Figure 2 is an end view of the same with a portion removed.
Figure 3 is an end view of a valve, hereinafter described.
Like letters indicate the same parts throughout the Drawing.
The said apparatus is constructed with a case or box a, which is connected on
one side with the supply pipe b from the main, and on the other side with the
discharge or delivery pipe c from which the water is to be drawn. Within the
said case or box a I arrange a valve d, which is closed by pressure in the outlet or
delivery pipe c against the action of a controlling spring e or a weight. I prefer
that the box a should be formed in three pieces or parts a¹, a³, a³. The part a' is
connected with the supply pipe b, and contains the valve d and the valve seat d¹;
the part a² is connected with the discharge pipe e, and is provided with a diaphragm e¹
of india-rubber or other flexible material; and the part a³ forms a cover, placed
over the said diaphragm.
The valve d is preferably constructed in the form of a cylindrical weight,
suspended by a flexible strap or sheet or sheets f, preferably of india-rubber or
other like material, interposed between the said cylindrical weight and the seat d'
in such a manner that when the valve descends the said india-rubber or other
material makes a perfectly tight joint between the valve and seat d', and also
allows the said valve to rise and descend with the slightest possible friction. The
seat & preferably consists of a disc of_india-rubber-or-other-like-material, which
surrounds the orifice or aperture a³. a represents a concave offset or projection
below the aperture in the partition. The said disc or flexible material extends
over this offset, which is so formed that the part of the flexible disc covering it
conforms to the contour of the valve d when the same is down, thereby ensuring
the effectual closing of the aperture.a³.
An arm g attached to the valve d projects through the orifice or aperture a³ in
the partition a*, and is connected with a rod or link g' which is jointed to a rod
or spindle g that passes centrally through the diaphragm e, and is secured and
made watertight therein by nuts and washers, as shewn, or by other suitable means.
The said rod or spindle gå also passes through the cover a³, and has its upper end
arranged in combination with the controlling or regulating spring e, as shewn in

page_text: Figure 1. This spring is carried by a bracket h formed on or attached to the
cover a³, and provided with an adjusting screw h¹ or other device for regulating
or varying the tension or pressure of the said spring; or in place of the spring e a
weight may be used if found more convenient or desirable under any particular
circumstances, and a butterfly or other suitable valve may be used if desired,
although I prefer to use the valve above described in all cases where it is desired
to perfectly close the orifice in the partition.
When this apparatus is properly connected with the supply and delivery pipes
the pressure to be maintained on the delivery or discharge side of the valve must
be first determined, and, the spring or weight must be adjusted or regulated to this
pressure. This adjustment or regulation having been properly effected it will not
be possible for the pressure in the delivery pipes to exceed the determined amount
or degree, whatever may be the pressure or variations of pressure in the main or
other pipes on the supply side of the valve. The slightest excess or preponderance
of pressure on the delivery side of the valve will overcome the resistance of the
spring; the valve d will then close and will remain closed until by the opening of
one of the cocks or valves in or connected with the delivery or discharge pipe, or
by leakage, the pressure in the said pipe is reduced; the spring e then opens the
valve d and allows sufficient water to pass through the orifice a³ to restore the
pressure in the discharge pipe c, the said valve then closing immediately. Thus
it will be seen that the said apparatus is very effectual for controlling or limiting
the pressure in the pipes without obstructing, diminishing, or stopping the supply
of water.
My improved apparatus may be constructed of any required dimensions, and
used under all circumstances where it is desirable to control fluid pressure in the
manner above specified.
Having thus fully described my said Invention, and the manner of performing
the same, I wish it understood that I claim,-
First. The valve, consisting of a cylindrical weight attached to a flexible sheet
or strap arranged in contact with the india-rubber or other face or scat of the
partition which separates the supply side from the delivery side of the said
regulator, which valve acts in such a manner as to effect the tight closing and the
opening of the orifice or aperture in the said partition, as and for the purposes
specified.
Second. Providing the said partition with a concave portion or offset below the
said aperture, so arranged that the valve when in its lowest position will act in
combination with the said offset, as and for the purpose specified.
Third. In my improved fluid pressure regulator the coinbination of the aforesaid
valve, or any other suitable valve, with a diaphragm, controlled by a spring or
weight, as above described and for the purposes specified.
Fourth. In the said regulator the combination of the above described valve
arranged on one side of the partition, and connected with the diaphragm on the
other side of the same by means of a rod extending through the aperture in the
said partition and a link jointed to the said rod and to the spindle of the diaphragm,
substantially as described with reference to the Drawings, and for the purpose
specified.
In witness whereof, I, the said Charles Casimir Barton, have hereunto set
my hand and seal, this Tenth day of September, in the year of our Lord
