THOMAS SEAVILLE TRUSS, of 11, Ridinghouse Street Portland Place London W.
Civil Engineer IMPROVEMENTS IN VALVE AND PLUNGER OR PISTON COCKS FOR
REGULATING THE TRANSMISSION OF FLUIDS PASSING THROUGH THEM APPLICABLE
FOR WATER CLOSETS, URINALS AND OTHER PURPOSES.
These improvements consists in the construction and arrangement of valves and
plungers and valves with plungers or pistons attached thereto and in the con-
struction of Boxes chambers or vessels for containing the same and in the
mechanical combinations for regulating and giving motion to such valves plungers
or pistons and valves with plungers or pistons attached thereto whereby the
distance such plungers or pistons shall move and such valves shall open are
regulated and the quantity of fluids to pass such such valves in a given time are
determined according to the pressure exerted by or on the fluids transmited
through such plunger or piston and valve cocks.
The first part of my said Improvements consist in constructing an oblong box
with an inlet pipe or orifice at about the centre of it longitudinally through which
the fluid is admited into such box one end of such box being constructed to
receive a plunger and the other end to receive a disk valve, which I name the
discharge valve on the outer edge of an orifice formed therein the outer edge of
such orifice being formed as the dull edge of a knife and projecting from such end
of the box outwards. The orifice at this end of the box on which such discharge
CD

page_text: disk valve acts being of less area than the area of the other end of the box in
which the plunger works which plunger and discharge valve are connected
together by a spindle passing through and fixed to them one or both ends of
which spindle may work in guides so that motion given to the plunger is also
motion to the discharge valve, and around the end of the box on which the
discharge disk valve acts a cap or cover is formed and attached to such end of
the box for such discharge disk valve to work in with a guide in the same to
receive the end of the spindle passing through such discharge disk valve and
to this cap or cover an outlet pipe is attached for the discharge of the fluids trans-
mited through such valve and plunger Cocks-To open the discharge valvo
motion is given to the plunger and discharge valve attached to it by means of
pressure on or at the end of the plunger or end of the spindle to which it is fixed
that is constructed to protrude outside the box at the plunger end thereof by
means of a lever one end of which works on a pin for its fulcrum fixed on one
side of the orifice in the box at the plunger end thereof which lever acts at about
its centre on the end of the plunger or plunger and valve spindle that protrudes
from the box and to the other end of this lever a double wedge form block is
attached by a screw bolt bolt to regulate the distance that the extreemn height of
such double wedge form block shall project from the face of such lever and thereby
determine the distance the plunger shall move and the discharge valve open
motion is given to this lever by means of a friction roller working on a pin that is
fixed on another lever at a distance from its fulcrum which fulcrum is a pin fixed
to the side of the plunger end of the box at and such part thereof that by raising
or lowering the other end of this lever the friction roller on such lever shall act on
the double wedge form block attached to the lever first described and so move the
plunger and open the discharge valve by forceing it from its seat tho distance it is
regulated to open by the friction roller acting on the incline surfaces of the double
wedge form block until such friction roller is forced passed the extreem height of
the double wedge form block by the upward or downward motion of this lever
For some purposes I modify the foregoing arrangements for opening the
discharge valve by employing only the first mentioned lever on which I so place
the double wedge form block that the same shall act on the spindle to which the
plunger and discharge valve are attached to move the same and so open the
discharge valve by the upward or downward motion of such lever
For some purposes I substitute for the herein before described lever motions a
bar with the double wedge form block attached thereto with an adjusting screw
which. bar works in a frame that is attached to the plunger end of the box and so
arranged that in its upward or downward motion the incline plain surfaces of the
double wedge form block attached to such bar shall act on the spindle to which the
plunger and discharge valve or valves are attached to move the same and so open
the discharge valve and in this arrangement for some purposes I form a screw nut
to fit on the end of the plunger and discharge valve spindle and in this nut fit a
friction roller for the double wedge form block attached to the bar to act on to
open the discharge valve which nut may be turned to approach or recced from the
double wedge form block on the bar and thus regulate the distance the discharge
valve shall open. For some purposes I apply a spring to act against the top of the
plunger and the end of the box and also a spring to act against the discharge valve
end of the spindle and the cap at that end of the box for the further adjustment
of such valves and plungers which springs are regulated by means of set screws
acting on such springs to compress them as may be required
By these means any desired quantity of fluids are regulated to pass such
discharge valves for each opening of the same according to the pressure of or on
such fluids admited into the box through the inlet pipe and acting on the area of
the plunger and on the area of the discharge valve as the area of the plunger is
greater than the area of the discharge valve the pressure on the plunger overcomes
the pressure on the discharge valve and so closes the same in a given time and

page_text: holds such valve tight to its seat after such discharge valves have been opened as
in manner herein before described.
For some purposes I modify the foregoing arrangement of plunger and discharge
valve and substitute for the plunger herein before described a valve or plain disk
of the same area as the plunger and attach to this valve any suitable flexible
materiable of larger area than such valve which will admit of such valve moving
when fixed to such flexible material the surface of which flexible material may be
flat convex concave or any other suitable form and through this substituted valve
the spindle attached to the discharge valve is fixed and the flexible material so
fixed to such substituted valve is secured to the plunger end of the box by means
of a cap or cover and through this cap or cover the end of the spindle to which
such valves are fixed protrudes to be acted on by any one of the arrangements
herein before described for noving such spindles and opening such valves The
action by the pressure of or on the fluids acting on such valves being similar for
closeing the discharge valve as the action on the plunger and discharge valve as
herein before first described
Another modification of my said Improvements consist in the construction of an
oblong box to receive a plunger and valve attached thereto and also a loose disk
valve to work on a rod This box is constructed with a division in it for part of
its length so as to form two apertures or chambers in the same and to one end
of such box an inlet pipe is attached over an orifice made therein through which
the fluids are admited into such box and at this part of the box both of the
aperturers forned therein are open to receive the fluids passing into such box and
through one of these apertures the fluids passing into the box are discharged and
this aperture at a short distance from the inlet pipe is increased in area and at
this junction and around the end of the aperture of smaller area a raised pro-
jection is formed as the dull edge of a knife to make the seat for the disk discharge
valve and at this part of the box in the aperture of increased area an orifice is
made in one side of the box and an outlet pipe is attached through which the
fluids passing through the box and by the discharge valve are discharged The
discharge valve which covers and acts on the end of the aperture of the lesser
area is attached to a plunger by a spindle passing through and fixed to them
which plunger works in the aperture of the larger area in a line with the aperture
of lesser area through which the fluids are transmited to be discharged the end
of such valve and plunger spindle passes through the plunger end of the box and
through a stuffing box formed thereon and projecting outside such end of the
box, and within the box at the plunger end thereof the two apertures formed by
the division in the box are in connection at a point above the distance that the
top of the plunger moves to in the larger area aperture and at the inlet pipe end
of the box at the end of this connecting aperture a larger area is formed in the
box to receive a loose disk valve and around the end of this connecting aperture
a projection is formed as the dull edge of a knife to make the seat for the loose
disk valve which I name the regulating valve which valve covers and acts on this
end of the connecting aperturo which loose disk regulating valve works on a rod
with a collar on one end thereof on which collar such regulating valve rests and
on which it is raised from its seat the other end of such rod having a screw thread
formed on it which passes through a nut in a cap or cover fixed on this the inlet
pipe end of the box and on this rod between the inside of such cap with nut in it
and the top side of such regulating valve a coil spring is applied which acts on such
regulating valve to force it to the collar on the end of the rod that it works on so
that by turning the end of this rod that projects outside the cap at this the inlet
pipe end of the box by means of the screw thread on such rod working in the nut
in such cap the rod is drawn outwards to raise such regulating valve from its scat
on the end of the connecting aperture or is forced inwards for to admit of such
regulating valve taking its seat on the end of such connecting aperture. The end
of the plunger and discharge valve spindle that projects outside the plunger end of

page_text: the box is operated on by any one of the arrangements herein before described
for moving such plungers and opening the discharge valves attached thereto but
in this case the plunger and discharge valve are drawn outwards. By these
arrangements when the plunger with the discharge valve attached is drawn out-
wards the discharge valve is drawn from its seat and the fluid passing through the
box is discharged through the outlet pipe and the fluid between the top side of the
plunger and the end of the aperture in which it works is forced by the action of
the plunger when opening the discharge valve through the connecting aperture
and by the regulating valve into the inlet pipe end of the box after which action the
regulating valve assumes the position it is regulated for to allow of a given quantity
of fluid to pass through such connecting aperture to act on the plunger to again close
the discharge valve in a given time and thus regulate the quantity of fluid that shall
be transmited through such valve and plunger cock for each opening of the same
For some purposes 1 modify the arrangements last described by attaching to
the discharge valve a valve or disk of the same area as the plunger and
to this disk I attach a suitable flexible material of larger area than such
disk which will admit of such disk and discharge valve attached thereto
moving the flexible material to which such disk and valve are attached is
held in position within the box and in the larger area thereof on an area
constructed to receive the outer edge or area of such flexible material by means of
a ring the internal area of which is larger than the area of the disk attached to the
discharge valve and through this ring and the outer edge or area of the flexible
material attached to such disk and over the connecting aperture an orifice is
formed for the fluid to pass from the inlet pipe end of the box through the connecting
aperture to act on such disk with the discharge valve attached thereto and above
and on this ring another piece of flexible material is placed the surface of which
may be flat convex concave or of any other suitable form and to this piece of
flexible material a disk similar to the one just described and of like area is attached
and to this disk a spindle is attached which passes through the cap or cover of this
end of the box which cap or cover holds the flexible material attached to the disks
as also the ring firm to their positions on this end of the box and the end of the
spindle attached to the last described disk passes to the outside of this end of the
box to be acted on by any one of the arrangements herein before described for
opening the discharge valves of such valve and plunger cocks.
For
The action of the last described arrangements of disk valve with spindle (which
acts like a plunger) and disk valve with discharge valve attached is such that
when the spindle with disk attached is pressed towards the other disk that as the
discharge valve attached to it the fluid between such disks is forced by such action
through the connecting aperture and by the regulating valve into the inlet pipe
end of the box after which action the regulating valve assumes the position it was
moved from by the passing of such fluid and when the pressure is removed from
the spindle of the disk such disk receeds and the discharge valve opens and the
quantity of fluid permitted to pass by the regulating valve passes between such
disks to act on the same and thus close the discharge valve in a given time.
some purposes I modify the foregoing arrangements and substitute for the disk
with a spindle and disk with discharge valve attached thereto a short plunger with
discharge valve attached to the same the area of the plunger being larger than the
area of the valve and construct on one side of the box another aperture from the
top side of the plunger to the outlet pipe in the box for the fluid to pass through
from the top side of such plunger and on the end of such aperture at the plunger
end of the box a disk relief valve is formed to act the spindle of which relief valve
passes to the outside of the box to be acted on by any one of the arrangements
herein before described for opening the discharge valves The action of this last
described arrangement is that when the relief valve is opened the fluid on the top
side of the plunger passes out into the outlet pipe and the discharge valve is forced
open by the fluid acting against it and when such relief valve is closed by being

page_text: releved of the pressure that opened it the fluid passing by the regulating valve
from the inlet pipe end of the box acts on the plunger with discharge valve attached
and closes the valve by forceing the same to its seat in a given time as it may be
regulated for by the regulating valve-As my said Improvements are capable of
various modifications without departing from the principle thereof I do not restrict
myself to material or dimensions or the precise form or placement of the several
parts thereof or to the packing material to be used in connection with the plungers
or stuffing boxes or to the opening of such valves in such cocks in all cases by any
mechanical actions inasmuch that for some purposes such discharge and relief
valves as described may be opened by direct pressure of the hand on the spindles
of such valves

THOMAS SEAVILLE TRUSS of N° 11 Ridinghouse Street Portland _Place
London W Civil Engineer IMPROVEMENTS IN VALVE AND PLUNGER OR PISTON
COCKS FOR REGULATING THE TRANSMISSION OF FLUIDS PASSING THROUGH THEM
APPLICABLE FOR WATER CLOSETS URINALS AND OTHER PURPOSES
My said improvements consist in the construction and arrangement of regulating
release or relief valves and plungers or pistons and discharge valves with plungers
or pistons attached or connected thereto and in the construction of boxes or
vessels for containing such valves and plungers or pistons and in the mechanical
combinations for regulating and giving notion to such valves plungers or pistons
and discharge valves with plungers or pistons attached thereto whereby the
distance such plungers or pistons shall move and such discharge valves shall open
are regulated by wedge or cam actions on plain or rotary and the quantity of
fluid to pass such discharge valves in a given time are determined according to
the pressure exerted by or on the fluid transmitted through such valve and
plunger or piston locks.
The first part of my said improvements consist in constructing an oblong circular
box with an inlet pipe or orifice at about the centre of it longitudinally through
which the fluid is admitted into such box and about one half of such box is
constructed to receive a piston and the end of the other half of the box is
constructed with a seat for a discharge valve to act on over an orifice or aperture
formed therein which discharge valve is of cone form from its seat to further
prevent concussion in the box when the valve is closing the orifice or aperture at
this end of the box on which the discharge valve acts being of less area than the
area of the other part of the box in which the piston works which piston and
discharge valve are connected together by a spindle passing through and fixed to
them one or both ends of this spindle working in guides one of such guides acting
as a dividing or separating plate for directing the course of the fluid in the box
and as the discharge valve and piston are fixed to this spindle motion given to the
piston is also motion to the discharge valve and over the end of the box on which
the discharge valve acts a cap or cover is formed for such discharge valve to work
in and to this cap or cover an outlet pipe is attached for the discharge of the fluid
transmitted through such valve and plunger or piston cock The mechanical
combinations for opening the discharge valve to admit of the fluid being transmitted
through such valve and plunger or piston cock consist of a cap or cover with a
frame attached thereto and fixed on the piston end of the box which cap or cover
receives one end of the spindle to which the piston and discharge valve are fixed
and in this end of the spindle is fitted a friction roller and in a longitudinal centre
line with it a like friction roller is fitted in the frame and between these friction
rollers a bar works on which a double wedge is formed on either or both sides
projecting from the surface of the bar at about its longitudinal centre thereof the
breadth of such wedge regulating the distance the discharge valve shall opon and
to one end of this bar a lever is attached by means of a joint aud pin passing
through them which lever works on a pin for a fulcrum that is fixed to one side
of the box so that by moving the end of the lever to or fro motion is given to the
bar and the double wedge formed thereon passes between the friction roller in the
end of the valve and piston spindle and the friction roller in the frame and thus
opens the discharge valve and when it is desired that such discharge valve shall
complete its opening after pressure is applied on the end of the lever to force the

page_text: discharge valve from its seat a given length of the lever is constructed of flexible
material so as to bend a given distance when the pressure required to move the
discharge valve from its seat is exerted and in conjunction with this action the
double wedge on the bar is constructed with decreasing gradient from a point
above the surface of such bar which gives a curved form of wedge so that tho
spring given to the lever by the pressure applied thereon shall complete the
opening of the discharge valve For some purposes I apply a spring to act
against the piston from the frame cover and also a spring to act against the
discharge valve from the cap at that end of the box for the further adjustment of
the action of such discharge valves and pistons.
By these contrivances any desired quantity of fluid is regulated to pass such
discharge valves for each opening of the same according to the pressure of or
exerted on the fluid admitted into the box through the inlet pipe and acting on
the areas of the piston and discharge valve the area of the piston being greater
than the area of the discharge valve the pressure on the piston overcomes the
pressure on the discharge valve and so closes the same in a given time
according to the difference of such areas and the distance the discharge valve is
opened
The second part of my said improvements consist of a modification of the
arrangement herein before first described by the application of a regulating valve
that is constructed to work on the spindle connecting the discharge valve and
piston between the discharge valve and the piston and in the piston end of the
box at a point clear of the travel of the piston and between the piston and
discharge valve a seat is formed with an orifice or aperture through it for such
regulating valve to act on which regulating valve is kept to its seat by a spring
acting against it from the guide plate in the box through which the spindle passes
and through the regulating valve seat a hole is made for a communication for the
fluid to pass through to act on the piston the size of such hole determining tho
quantity of fluid that shall act on the piston in a given time and so close the
discharge valve connected to such piston in a given time and when it is desired to
vary this time at will a hole is made into this communication from the outside of
the box and a screw bolt or time screw is inserted to partially close such
communication at will and so regulate the flow of fluid to act on the piston to
close the discharge valve connected to it such communication may also be mado
by a hole through the regulating valve or by the regulating valve not being
allowed to approach within a given distance to its seat by a projection on its rim
forming a stop for that purpose By this arrangement when the piston is being
moved and the discharge valve opened the fluid that is between the piston and
the regulating valve lifts such regulating valve and passes thereby and afterwards
such regulating valve resumes its seat by the action of the spring acting against it
when the fluid again passes through the communication as before described to act on
the piston to force it back again and so close the discharge valve connected to it
and by this arrangement the same valve and plunger or piston cock can be
regulated at will to pass different quantities of fluid.
The third part of my said improvements consist of a modification in the
placement of the regulating valve hereinbefore described in the second part of
my said improvements and this is effected by constructing a division in the box
at a point clear of the travel of the piston and between the piston and the
discharge valve through which division the spindle connecting the piston and
discharge valve passes and from a point between this division and clear of the
travel of the piston an aperture is formed in the side of the box to a point between
the division and the discharge valve and on this end of the aperture a scat is forined
for the regulating valve to act on which regulating valve works on a spindle in a
cover at that part with a spring acting on it from such cover to keep it to its
seat The effect by this arrangement is the same as that described in the second
part of my said improvements.
The fourth part of my said improvements consist of a modification in the

page_text: arrangements hereinbefore described by substituting for the piston hereinbefore
described a disk of the same area which disk is fixed to the connecting spindle in
like manner as the piston herein before described and to the disk is attached any
flexible material of larger area than such disk the surface of which may be flat
convex, concave or of any other suitable form which flexible material is fixed to
this end of the box by the bar frame cover hereinbefore described-The effect of
this arrangement is the same as that herein before described as due to the piston
The fifth part of my said improvements consist of a modification in the
placement of the inlet and outlet pipes attached to the box and consist of
attaching the inlet pipe to near one end of the box and the discharge pipe at
about the centre of the box longitudinally and at a point between the inlet pipe
and the outlet pipe a seat is formed in the box for the discharge valve to act on
and the area of that part of the box in which the discharge valve works is larger
than the area in the end of the inlet pipe part of the box on which the discharge
valve acts and to this discharge valve the piston is connected by a spindle in
manner hereinbefore described which piston works in the same part of the box as
the discharge valve but of larger area than such discharge valve and at a point
clear of the travel of the piston in this part of the box and between the piston
and this end of the box or aperture is formed in the side of the box to a point
between the discharge valve seat in the box and the inlet pipe and on this end of
the aperture a seat is formed for the regulating valve to act on which regulating
valve works on a spindle in a cap or cover at that part with a spring acting on it
from such cap or cover to keep it to its seat. The effect of this arrangement is
similar to that hereinbefore described in the second third and fourth arrangements
of my said improvements except that in this arrangement the fluid acts on the
back of the piston to close the discharge valve connected to it.
The sixth part of my said improvements consist of a modification of the
arrangement herein before described in the second part of my said improvements
by the addition of a second piston and in this arrangement the discharge valve
and piston are connected together in manner herein before described and this
second piston is fixed to a spindle that is alone acted on by the double wedge on
the opening bar which second piston is arranged so as not to come in contact with
the piston connected to the discharge valve but to leave a space between such
pistons and the seat for the discharge valve in this arrangement is formed within
the end of the discharge valve end of the box so that the discharge valve shall
recede to open By this arrangement when the second piston is forced towards
the piston with the discharge valve attached the fluid between such pistons is
forced passed the regulating valve and when the spindle of such second piston is
relieved from pressure such piston recedes and the piston with the discharge valve
connected to it also recedes by the pressure of the fluid acting on it from the infet
pipe part of the box and thus opens the discharge valve such discharge valve
being again closed by the fluid admitted through the communication herein before
described to act between the two pistons the second piston being at rest the
piston with the discharge valve connected to it is forced forward and the discharge
valve is so closed By this arrangement the discharge valve does not open until
the second piston is relieved from pressure -
The seventh part of my said improvements consist of a modification of the
arrangements herein before described in the sixth part of my said improvements by
the addition of a second regulating or release valve and a second aperture which
is connected with the outlet pipe and in this arrangement the discharge valve and
piston are connected together in manner herein before described (but the second
piston is not employed) and in the end cap or cover with fraine attached in which
the opening bar works this second aperture is formed through one side of the
same from the inside face thereof and also in the side of the box to the outlet pipe
and over the end of this aperture and on the inside face of such cap or cover a
seat is formed for the second regulating valve to act on to which regulating valve
a spindle is attached which passes through such cap or cover the end of such

page_text: spindle having a friction roller fitted therein to be acted on by the double wedge
on the opening bar as in manner hereinbefore described By this arrangement
when the spindle attached to this second regulating valve is acted on by the
double wedge on the opening bar such regulating valve attached thereto is forced
from its seat and the fluid between the piston and this end of the box passes out
by such regulating valve and through the second aperture into the outlet pipe and
the piston with the discharge valve connected thereto recedes and the discharge
valve opens by the pressure of the fluid acting on it and when this second regu-
lating valve spindle is released from pressure the regulating valve attached to it
closes again by the spring acting against it when the fluid admitted by the time
screw through the communication herein before described again acts on the piston
and thus moves the same and so closes the discharge valve.
The eighth part of my said improvements consist of a further modification of
the sixth part of my said improvements as herein before described by making the
aperture between the piston end of the box and the discharge valve end thereof
through the piston with discharge valve attached instead of as described in the
sixth part of my said improvements and on the side of this piston and facing the
discharge valve a scat is formed on the end of such aperture for the regulating
valve to act on and the regulating valve is arranged to work on the spindle
between this piston and the discharge valve with a spring to act against it from
the guide plate in the box to keep it to its seat-By this arrangement when the
second piston is forced towards the piston with the discharge valve connected to it
the fluid between such pistons is forced passed such regulating valve and when
the spindle of the second piston is released from pressure it recedes as do also the
piston with the discharge valve connected to it by the pressure of the fluid acting
on it and so opens the discharge valve when the regulating valve closes by the
spring acting against it and again the fluid passes through the time hole in the
regulating valve and thus acts between the two pistons and moves the piston with
discharge valve attached thereto and so closes such discharge valve-The effect of
this arrangement is the same as that herein before described in the sixth part of
my said improvements
I have described the lever for some purposes as constructed with a spring in it
for a given length but the like result can be obtained by a pin with a head to it
passing through the lever with two springs on each pin one on each side of the
lever and the other end of the pin being fixed in the end of the opening bar Or
the opening bar may be made hollow with a stop in the centre thereof and a
spring applied on each side of such stop with a pin from the lever passing through
them and having collars on it to hold such springs in position and compress them
in either direction by motion of the lever-The several parts of my said improve-
ments are held together by screws, screw bolts or any of the contrivances usual
for such purposes
In order that the nature of my said improvements and in what manner the
same are to be performed may be more fully understood I will proceed to describe
the several Figures on the sheet of Drawing hereunto annexed

As my said improvements are capable of various modifications without departing
from the principle thereof I do not restrict myself to material, dimensions or the
precise form or placement of the several parts thereof or to the packing material
to be used in connection with the plungers or pistons and spindles or to the opening
of the discharge valves in all cases by any mechanical motions inasmuch that for
some purposes such valves may be opened by direct pressure from the hand on the
spindle to be operated on.

the same are to be performed I declare that I claim as my Invention the arrange-
ments of valves plungers or pistons and the mechanical combinations for valve
and plunger or piston cocks for regulating the transmission of fluids passing
through them applicable for Water Closets Urinals and other purposes as herein-
before described
