Passage of Steam, Water or other Fluids.
WILLIAM HENRY THOMPSON, and ROBERT THOMPSON, both of 155, Fenchurch
Street, London, E.C., Engineers, do hereby declare the nature of this invention
to be as follows: -
Our invention has for its object improvements in stop valves or valves employed
for stopping or controlling the flow of steam, water or other fluids (hereinafter
called Huid) whereby the seatings or fluid controlling parts or surfaces of the said
valves or those parts which are subject to the most wear and tear are arranged
or combined so as to be readily or efficiently adjusted or set into proper working
position in the body (or casing) of the valve or withdrawn from it for examination
renewal or repair; also for the more efficient direction and control of the force
of the fluid acting on the valve or of its passage through it.
In carrying our invention into practice we arrange the body or casing of the
valve (hereinafter called the body) with an aperture on its top surface (hereinafter
called the top aperture)-assuming the valve spindle to be in a vertical position
with the hand wheel uppermost-of suitable form for receiving and holding the
stem of the valve cup as hereinafter mentioned and we arrange the bottom surface
with an aperture (hereinafter called the bottom aperture) for the passage or
withdrawal of the valve cup valve and spindle and parts or surfaces connected
or combined therewith as hereinafter nientioned such bottom aperture being
screwed for the reception of a screw cover by which it is sealed when the valve
is in operation, and we form or prepare the surface part or partition of the body
(usually prepared as or for the valve seating) so as to receive and hold in position
or form a joint or union with the aforesaid valve cup (as hereinafter mentioned)
so that such surface is hereinafter called the valve cup seating.
The said valve cup is a hollow casting or part preferably made in the form of
a cup or bell which assuming it to be in an inverted position has a rim (or
shoulder) formed around its mouth or bottom end or at or near its largest circum-
ference (hereinafter called its bottom end) the upper surface of such rim is
prepared so as to form a suitable joint with the aforesaid valve cup seating when
drawn or set up to it as hereinafter mentioned; the bottom surface of the said rim
and valve cup is formed or prepared as the valve seating from which the cup
extending upwards terminates with the hereinbefore mentioned stem formed with
a hole through it into the cup for the passage of the valve spindle, the said
hole being formed with a suitable number of screw threads along part of its
surface so as to form a nut for the screw cut on the valve spindle which spindle
is connected at its lower end with the valve in a suitable manner while its
upper end passing through the hole extends beyond or above the stem a sufficient
distance for its proper connection with the hand wheel by which it and the valve
are operated by turning the spindle so as to work its screw in the nut in the
usual manner, the escape of the fluid around the spindle is prevented by a

page_text: gland nut containing packing and working on a screw formed on the stem
which screw is of such a length as to enable it not only to be employed as a
gland screw but to be utilized as a means for drawing the upper surface of the
Tim of the aforesaid valve cup into contact with the valve cup seating by means
of a second nut rim or worked on the said screw so as to preceed and be worked
in advance of the gland nut until it bears on the top surface or shoulder of the
herein before mentioned top aperture and pulls on the screw and valve cup with
sufficient force to draw the aforesaid upper surface of its rim into such contact
with the valve cup seating as to form a joint for preventing the escape of the fluid
between their surfaces and at the same time holding the moveable combination
of the valve cup, valve seating, valve and valve spindle and its screw and nut and
handle wheel and gland nut and screw (hereinafter called the combination of
wearing parts) in proper working relation with the body of the valve. Suitable
apertures are formed in the valve cup opening into outlet part or division of the
body so as to admit of the passage of the fluid from the inlet division or partition
of the body through the open valve and valve cup into the outlet.
After removing the screw cover from the bottom aperture the combination of
wearing parts are withdrawn for examination by removing the hand wheel and
running back or off the gland nut and second nut of the gland screw so as to
admit of the passage of the stem through the top aperture, the combination is
replaced by passing it up through the bottom aperture until the upper surface
of the aforesaid valve cup rim is in contact with the valve cup seating and the
stem projects through the top aperture when the nuts and hand wheel are replaced
and also the screw cover when the valve is in working order.
The valve may be composed of renewable seating or parts as may be found
expedient in the herein before arrangement; the force of the fluid is directed on
the back of the valve and the bottom surface of the valve cup so that when the
valve is closed both the valve and the valve cup are forced on to their seatings
with more or less force as the pressure rises and falls while the pressure being
entirely resisted by the said seating the valve spindle and its screw and nut
are relieved from the strain of the constant pressure the force of which also acts
on the valve cup rim holding it up to the valve cup .seating so that it does not
depend entirely on the pull or force exerted by the second nut on the gland nut
screw for the pressure with which it contacts with the seating.
Suitable packing may be employed between the various surfaces
A suitable compression spring may be interposed between the valve and the
under side or other suitable part of the valve cup so as to keep the valve cup
and its rim aforesaid up to the valve cup seating by its pressure, in the absence
of the fluid pressure. the said spring may be arranged in a manner to be compressed
by the pressure of the fluid in the action of closing the valve and the force acquired
by such compression utilized in assisting the hand of the operator in opening the
valve or the said spring or its action may be similarly employed in any modifica-
fion and arrangement of the valve cup valve or spindle which spindle may also
be arranged with the necessary shoulder or shoulder surfaces worked or provided
with suitable bearing surfaces for supporting or resisting the thrust of any of the
forces acting on it.
The valve may be adapted for automatic action by connecting the part of the
spindle extending beyond the gland nut with a suitable rack and providing
suitable bearings (or supports) on the body of the valve for carrying a spindle
arranged or formed with a pinion (or spur wheel) the said bearings being so
arranged as to bring the pinion into gear or proper working relation with the
rack while a coiled or clock spring is connected at its central end with the
spindle and at its outer end with the case or cylinder in which it is contained
(hereinafter called the spring case) which case takes its bearing and works on the
spindle (hereinafter called the pinion spindle) and may be turned by a direct
application of the hand and held in position by a suitable pawl and ratchet wheel

page_text: formed or connected with it or when the power required for winding up is too
much for the direct application of the hand or the necessary adjustment of the
spring too infinitesimal for it to be regulated by the pitch of the ratchet teeth
we form or arrange the spring case with a worm wheel which we operate by a
suitably arranged worm connected with and operated by a suitable hand wheel
or handle, the spring is coiled or wound in the direction necessary for turning
the pinion spindle and pinion so that it will work the rack downwards or in the
direction, necessary to pull or force the valve against the opposing force of the
fluid so as to control its passage past or through the valve in such a manner that
it passes from the valve with its force reduced in proportion to the adjustment
of the spring or the force it is exerting on the valve, the spring case may be
stationary and the spring wound and set by operating and holding the pinion
spindle by a suitable application of ratchet wheel and pawl or worm wheel and
worm or other suitable mechanism or devices may be employed for winding and
adjusting the force of the spring or the spring force may be communicated to
the valve spindle by means of a cam on the pinion spindle working in contact with
a suitably arranged lever connected to or operating with the valve spindle to which
the spring force may be communicated by any other suitable arrangement of a
lever (or levers) or other mechanism.
The aforesaid arrangement and combination of spring and mechanism or parts
by which it is wound or adjusted or its power utilized may be arranged for
controlling any valve or arrangement of valve (or valves) hereinbefore mentioned
or any other form or arrangement of valve for which such spring and mechanism
or parts may be adapted or applicable.
Two or more of the aforesaid valves and valve cups or seatings and springs or
mechanism and parts by which they are controlled or set in position may be
grouped so that the fluid may pass from one to the other in order to sustain a more
uniform delivery or passage of the fluid.
The application or arrangement of the hereinbefore mentioned arrangement or
combination of wearing parts may be modified or varied according to the design
of the valve body or casing or arrangement of inlet and outlet passages screwed
ends or flanges or other provision for connecting with the piping or apparatus
to which the valve may be applied.
.
In order that the lift or movement of either of the hereinbefore mentioned
valves (hereinafter called the first valve) may be utilized to operate a second
valve so as to subject the fluid to a second control such second valve may be formed
or arranged with the first valve so that as the first valve opens it lifts or works the
second valve towards its seating or in the direction for closing it--the distance at
which the second valve shall be worked from its seating may be determined by
connecting it with a suitable spindle (operated by a handle wheel) screwed at its
lower end so as to screw into screw threads forming a nut in the first valve or
on or in a shank extending from it so that by turning the spindle the first and
second valves may be worked to or from each other-the arrangement of the
screw threads or spindle or spindles and valve may vary or the first valve may
be arranged to work the second valve at a distance or apart so as to open and close
it as aforesaid by means of suitable lever connection or connections arranged
according to the conditions of working or the design or arrangement of the
valve--the second valve may be controlled by the coiling or uncoiling of a spring
in a similar manner to the arrangement for controlling the first valve as herein-
before mentioned or any other suitable mechanism spring or springs for controll-
ing or communicating the necessary motion from the first valve to the second.

page_text: Improvements in Valves for Stopping or Controlling the Flow or
Passage of Steam, Water or other Fluids.
We, WILLIAM HENRY THOMPSON and ROBERT THOMPSON, both of 155, Fen-
church Street, in the City of London, Engineers, 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:-
Our invention has for its object improvements in stop valves or valves employed
for stopping or controlling the flow of steam, water or other fluids (hereinafter
called fluid) whereby the seatings or fluid controlling parts or surfaces of the said
valves or those parts which are subject to the most wear and tear are arranged
or combined so as to be readily or efficiently adjusted or set into proper working
position in the body (or casing) of the valve or withdrawn from it for examination
renewal or repair; also for the more efficient direction and control of the force
of the fluid acting on the valve or of its passage through it.
In the accompanying drawings
Figure 1 represents a vertical side elevation, part in section of one form of the
valve, and its operating mechanism.
Figure 2 represents a similar view of the valve and operating mechanism form-
ing a modification of our invention.
Figure 3 represents a view of the same in end elevation, partly broken away.
Similar letters refer to similar parts.
In carrying our invention into practice we arrange the body A (or casing) of
the valve (hereinafter called the body) with an aperture B on its top surface
(hereinafter called the top aperture)-assuming the valve spindle to be in a
vertical position with the hand wheel uppermost-of suitable form for receiving
and holding the stem of the valve cup as hereinafter mentioned and we arrange
the bottom surface with an aperture C (hereinafter called the bottom aperture)
for the passage or withdrawal of the valve cup, valve and spindle and parts or
surfaces connected or combined therewith as hereinafter mentioned. Said bottom
aperture C is screwed (or prepared) for the reception of a screw (or other suitable)
cover D by which it is sealed when the valve is in operation. We form or prepare
the part or partition E of the body (usually prepared as for the valve seating) with
a suitable surface to receive and hold in position or form a joint or union with
the aforesaid valve cup (as hereinafter mentioned) and such surface is hereinafter
called the valve cup seating F.
The valve cup G is a hollow casting or part preferably made in the form of a
cup or bell, which assuming it to be in an inverted position, has a rim (or
shoulder) H formed around its mouth or bottom end or at or near its largest
circumference the upper surface of such rim is prepared so as to form a suitable
joint with the valve cup seating F when drawn or set up to it as hereinafter
mentioned, the bottom surface of the said rim H and valve cup G is formed or
prepared as the valve seating I from which the cup G extending upwards
terminates with the hereinbefore mentioned stem J formed with a hole through it
into the cup for the passage of the valve spindle K the said hole being formed
with a suitable number of right or left hand screw threads along part of its
surface so as to form a nut for the screw cut on the valve spindle K which
spindle is connected at its lower end with the valve in a suitable manner while
its upper end passing through the hole extends beyond or above the stem Ja
sufficient distance for its proper connection with the hand wheel L by which it
and the valve are operated by turning the spindle so as to work its screw in the

page_text: nut in the usual manner. The escape of the fluid around the spindle is prevented
by a gland nut M containing packing and working on a screw formed on the
stem which screw is of such a length as to enable it not only to be employed
as a gland screw but to be utilized as a means for drawing the upper surface of the
rim H of the aforesaid valve cup G into contact with the valve cup seating F by
means of a nut N (hereinafter called the second nut) run or worked on the same
screw so as to precede and be worked in advance of the gland nut M until it
bears on the top surface or shoulder of the top aperture B and pulls on the screw
and valve cup G with sufficient force to draw the upper surface of its rim H into
such contact with the valve cup seating F as to form a joint for preventing the
escape of the fluid between their surfaces and at the same time holding the
movable combination of the valve cup G, valve seating I, valve O, and valve
spindle K and its screw and nut and handle wheel and gland nut M and gland
screw on stem J with second nut N (hereinafter called the combination of wearing
parts) in proper working relation with the body of the valve. If found desirable
under some conditions a separate screw may be formed on the stem to receive the
second nut instead of utilizing the gland screw. Suitable apertures P are formed
in the valve cup G, opening into outlet part or division of the body so as to
admit of the passage of the fluid from the inlet division or partition of the body
through the open valve and valve cup into the outlet.
After removing the screw cover D from the bottom aperture C, the combination
of wearing parts can be withdrawn for examination by removing the hand wheel L
and running back or off the gland nut M and second nut N of the gland screw
so as to admit of the passage of the stem J downwards through the top aperture B
and out at the bottom aperture C. The combination is replaced by passing it up
through the bottom aperture C until the upper surface of the valve cup rim H
is in contact with the valve cup seating F and the stem J projects through the
top aperture, when the nuts and hand wheel are replaced and also the screw
cover D and the valve is then in working order.
Suit-
A
The valve may be composed of renewable seating or parts as may be found
expedient in the hereinbefore arrangement; the force of the fluid is directed on
the back of the valve and the bottom surface of the valve cup so that when the
valve is closed both the valve and the valve cup are forced on to their seatings
with more or less force as the pressure rises and falls, while the pressure being
entirely registered by the said seating the valve spindle and its screw and nut
are relieved from the strain of the constant pressure the force of which also acts
on the valve cup rim holding it up to the valve cup seating so that it does not
depend entirely on the pull or force exerted by the second nut on the gland
screw for the pressure with which it contacts with the seating.
ablo packing may be employed between the various surfaces.
suitable compression spring may be interposed between the valve and the
under side or other suitable part of the valve cup so as to keep the valve cup
and its rim aforesaid up to the valve cup seating by its pressure in the absence of
the fluid pressure. The said spring may be arranged in such a manner as to be com-
pressed by the pressure of the fluid in the action of closing the valve and the force
acquired by such compression utilized in assisting the hand of the operator in open-
ing the valve. Or the said spring or its action may be similarly employed in any
modification and arrangement of the valve cup valve or spindle, which spindle may
also be arranged with the necessary shoulder or shoulder surfaces worked or provided
with suitable bearing surfaces for supporting or resisting the thrust of any of the
forces acting on it.
The valve may be adapted for automatic action (as shown by Figures 2 and 3)
by dispensing with the internal screw threads formed in the stem J and the
corresponding threads on the valve spindle K. so as to leave the spindle free to
reiprocate or to be operated by a coiled or clock spring by connecting the part
of the valve spindle extending beyond the gland nut with a suitable rack Q and
providing suitable bearings R (or supports) on the body A of the valve for carry-

page_text: ing a spindle S arranged or formed with a pinion T (or spur wheel) the said
bearings being so arranged as to bring the pinion T into gear or proper working
relation with the rack Q. A coiled or clock spring is connected at its central
end with the spindle S and at its outer end V with the case (or cylinder) in
which it is contained (hereinafter called the spring case W) which case W
takes its bearing and works on the spindle (hereinafter called the pinion spindle) S
and may be turned by the direct application of the hand and held in position by a
suitable pawl and ratchet wheel formed or connected with it; or, when the power
required for winding up is too much for the direct application of the hand or the
necessary adjustment of the spring too infinitesimal for it to be regulated by the
pitch of the ratchet teeth we form or arrange the spring case W, with a worm
wheel X which we operate by a suitably arranged worm Y connected with and
operated by a suitable handle or hand wheel Z. The coiled spring UV is coiled
or wound in the direction necessary for turning the pinion spindle S and pinion T
so that it will work the rack upwards or in the direction necessary to pull or
force the valve 0 against the opposing force of the fluid so as to control its passage
past or through the valve in such a manner that it passes from the valve with
its force reduced in proportion to the adjustment of the spring or force it is
exerting on the valve. The spring case may be stationary and the spring wound
and set by operating and holding the pinion spindle S by a suitable application of
ratchet wheel and pawl or worm wheel and worm or other suitable mechanism or
devices may be employed for winding and adjusting the force of the spring or the
spring force may be communicated to the valve spindle by means of an arrange-
ment of a lever (or levers) or other suitable mechanism.
The aforesaid arrangement and combination of spring and mechanism or parts
by which it is wound or adjusted or its power utilized may be arranged for
controlling any valve or arrangement of valve (or valves) hereinbefore mentioned
or any other form of arrangement of valve for which such spring and mechanism
or parts may be adapted or applicable.
Two or more of the aforesaid valves and valve cups or seatings and springs or
mechanism and parts in which they are controlled or set in position may be
grouped so that the fluid may pass from one to the other in order to sustain a more
uniform delivery or passage of the fluid.
