WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 13, Rue Gaillon,
Paris. "IMPROVEMENTS IN SELF-CLOSING VALVES."
This Invention of improvements in self-closing valves relates to a device whereby
a valve is made to be self-closing when the power used in opening it has been
removed, and is constructed so as to obviate the hydraulic shocks resulting from
thio varying pressure of the feed water, and consists,-
First. In connecting the regulating valve to two pistons of different diameters,
one situated above and the other below the said valve, and provided with a
peculiarly adjustable channel for the passage of the feed water to connect the
chambers situated above and below, and otherwise separated by the said pistons,
thus causing the valve proper to close by means of the excess of pressure brought
to bear upon the piston having the larger diameter.
Second. In placing an air chamber between the valve proper and feed water,
the entrance channel to the said chamber being partially obstructed by a diaphragm
In the accompanying Drawings Figure 1 is a partial sectional elevation of a
valve of this Invention, the air chamber and diaphragm in section while the valve
proper is in elevation; Figure 2 is a plan view of the same.
Figure 3 is a sectional elevation of the valve proper drawn to an enlarged scale,
and representing the air chamber removed.
Figure 4 is a transverse elevation; and Figure 5, a sectional plan through
line a, b.
In the annexed Drawings (A) represents a reservoir, which serves the purpose

page_text: of equalizing the uneven pressure resulting from the feeding process or from the
opening or closing of the valve, and greatly increases the durability of the valve and
pipes, while the diaphragm (a) having a small opening regulates the speed of the
water supply, thereby securing a quiet even flow of water through the valve and
a inore ready closing of the same, inasmuch as the water reaches the wide opening
to the valve after passing through a small opening in the diaphragın (a) and then
through a larger space, that of the reservoir (A).
The valve proper (V) consists of eight principal parts, viz.,—
The casing B, B¹.
The valve K', for shutting off the supply at (u).
The valve K, for shutting off the escape at (u').
The two regulating pistons and m.
The regulating valve rod f with valve at 8.
The counter current channels n, n¹, n¹¹, n¹, with valve at p.
The escape opening q for escapo pipe ".
The aperture b for the escape of air.
The regulating valve rod fenters the valve casing B through the stuffing box e,
which is secured to the upper part of the lid B' by means of a screw coupling.
The staple for tho reception of the lever g, h, i, is secured to the valve rod f by
Tucans of a screw coupling e' in such a manner as to permit the said rod to revolve
in the said screw coupling, for the purpose of regulating the speed of the valve K'
and K and pistons and m. Inside the casing B, B1, the valve rod f supports
the valve K', K", and pistons l, and m.
The chamber O is connected with the
chamber by means of the channels n, n¹, n", and valve 8, and again the
chamber is connected with the pressure supply ull by means of the valve and
channel. The chamber u communicates with the clevator pipe r and with
the escape pipe c¹; the stop screw c regulates the escape.
The closing of the aperture of supply at u is attained by means of pistons of
unequal diameters at land m, the piston at having the greater diameter, and
consequently the greater pressure surface, forces the valve K' to its scat at u; the
speed of the said valve can be regulated and the hydraulic shock obviated by
screwing together in a greater or less degree of the valve surface at 8, which occurs
when the valve rod fis screwed into the piston at f to a greater or less extent
by means of a rod inserted into the hole at . In this manner the opening cross
cut at 8, which communicates with the counter channels n, n', n¹, n¹¹¹, may be
narrowed or widened at pleasure, thereby securing a more or less rapid transfer of
water from the chamber O to the chamber O'.

WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 13, Rue Gaillon,
Paris. "IMPROVEMENTS IN SELF-CLOSING VALVES." A communication from abroad
by Ferdinand Behr, of Frankfort-on-Maine, Germany, and Eugene W. Lippert, of
Cincinnati, Ohio, United States of America.
This Invention of improvements in self-closing valves relates to a device whereby
a valve is made to be self-closing when the power used in opening it has been
removed, and is constructed so as to obviate the hydraulic shocks resulting from
the varying pressure of the feed water, and consists,―
First. In connecting the regulating valve to two pistons of different diameters,
one situated above and the other below the said valve, and provided with a
peculiarly adjustable channel for the passage of the feed water to connect the

page_text: The escape opening y for escape pip
The aperture b for the escape of air.
The regulating valve rod fenters the valve casing B through the stuffing box e,
which is secured to the upper part of the lid B¹ by means of a screw coupling.
The staple t for the reception of the lever g, h, i, is secured to the valve rod ƒ by
means of a screw coupling e¹ in such a manner as to permit the said rod to revolve
in the said screw coupling, for the purpose of regulating the speed of the valve K¹
and K and pistons and m. Inside the casing B, B', the valve rod f supports the
valve K, K, and pistons and m.. The chamber O is connected with tho
chamber O¹ by means of the channels n, n', n¹, and valve 8, and again the
chamber O¹ is connected with the pressure supply ull by means of the valve p and
channel n. The chamber ul communicates with the elevator pipe r and with
the escape pipe c¹; the stop screw c regulates the escape.
The closing of the aperture of supply at u is attained by means of pistons of
unequal diameters at land m, the piston at 1 having the greater diameter, and
consequently the greater pressure surface forces the valve K to its seat at u, the
speed of the said valve can be regulated and the hydraulic shock obviated by
screwing together in a greater or less degree of the valve surface at 8 which occurs
when the valve rod fis screwed into the piston lat fl to a greater or less extent
by means of a rod inserted into the hole at x. In this manner the opening cross
cut at 8, which communicates with the counter channels n, n¹, n", n, may bo
narrowed or widened at pleasure, thereby securing a more or less rapid transfer of
water from the chamber O to the chamber O¹.
A point of great importance in this construction is the fact that by attaining a
closing of the valve entirely free from any jar the durability of the whole apparatus
is greatly increased. The screw valve C is used for cutting off the supply when
repairs may be necessary. The entire apparatus is secured to a plate P by means
of screws.

page_text: All the brass parts in the interior of the apparatus may be nickel plated, thus
obviating the formation of verdigris and its deleterious effects on the health of the
public and increasing the durability of the valve.
The mode of operation is briefly described as follows:-When by means of any
of the familiar appliances the lever g, h, i, turning on a fixed axis at g is lifted, the
pistons and m and valve K', K", move in the same direction, being connected
with the lever g, h, i, by the valve rod fand the valve K", and then the leather
packing above the disc K shuts off the escape valve at u. The leather packing
beneath the disc K, and then the valve K' open the aperture at u, and the water
in the chamber O enters through the channels 8, n, m, n, into the chamber 01.
The water in the air reservoir A reaches the escape q in passing through u" and ",
and then through the elevating pipe 1.
and
When the upward draft ceases the difference of pressure between the large
piston and the small piston has its effect. The water in chamber O¹ forces
itself through the channel n", n', n, and through the valve s into the chamber O,
and here exerts its influence on the larger piston surface. The channel
valve effect the equalization of pressure between the supply and the chambers O
and O. The piston K in moving downwards shuts off the passage of water to the
escape at u, and K" opens the aperture to the rain pipe Cat u. The leather
packing below K closes completely at u, and the elevator pipe 7 empties itself into
the chamber 11, and finally through channel c¹ into the open air.
If it is desired to save the water which here escapes after each draft the least
waste of water may be entirely prevented by the insertion of a cylindrical vessel
between the valve and elevator pipe, as shown at D, and leading the water here
escaping into the elevator pipe by means of an injector adjusted at the bottom of
this cylindrical vessel, the water here accumulating in the vessel D after each draft
is carried away with each succeeding draft, thus obviating entirely any waste of
water.
Having thus described and particularly set forth the nature of the Invention,
I would have it understood, that what I claim as new and desire to secure in the
before in part recited Letters Patent is,―
First. The regulating valve rod revolvable at e and supplied with screw thread
at the bottoin, by means of which the valve surface at 8 may be increased or
lessened, thereby obviating the hydraulic shock in closing the valve.
Second. The peculiarly adjusted channels n, m, n, which enable the transfer
of water from 0 to 01, as and for the purpose specified.
Third. The peculiar construction of the channel and valve p, by means of
which the equalization of pressure is attained in the supply and in the chambers O
and O¹.
Fourth. The valve K, K, arranged to cut off the escape through channel C'
before the passage of water into the chamber 11, and in reverse order cuts off the
feed water before opening the entrance to channel c', substantially as and for the
purpose specified.
Fifth. The valve proper V in its combination and mode of operation, as and for
the purpose specified.*
In witness whereof, I, the said William Morgan-Brown, have hereunto set my
hand and seal, this Fourth day of November, in the year of our Lord
One thousand eight hundred and seventy-six.
