PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Operating Valves for Controlling
the Passage of Fluids.
I, HERBERT TROTT, of 75, High Street, Battersea, in the County of Surrey,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to means or apparatus for operating the valves employed
for controlling the passage of fluids and particularly the control of the passage of
water in baths or wash houses.
In carrying out my invention I employ say two valves of the description indi-
cated by me in the Specification of Letters Patent No. 15275 dated 9th November
1887 or other suitable form of valve to be either drawn or pressed to and from their
seats for opening or closing and the two valves have their valve pieces respectively
drawn to their seats by means of springs acting on the stems of the valve pieces so
as to give them a constant tendency to close to their seats. On the outer ends of
the stems are anti-friction wheels which come in contact with a circular rotatory plate
actuated by a hinged handle, or by a suitable lever or operating part. This rotatory,
plate is formed with rises depressions or other equivalent cam surfaces so that as it
is rotated the valve stems are pressed partly in, wholly in or left wholly out so as
to partly open, wholly open or leave closed one or both valves at one time, the cam
surfaces being arranged so that one valve say the cold water valve may by a move-
ment of a quarter turn of the handle plate be opened or by a like quarter turn in
the opposite direction the other valve may be opened instead-say for hot water-
whilst by a half turn in either direction both valves may be opened and both
temperatures admitted at once. By another movement of the handle on its
linge connecting it to the rotatory plate when the valves are off and the handle at
zero the waste plug may be raised from its seat and the water previously supplied
run off.
The same results may be attained by a modification in which for a rotatory plate
with cam surfaces to operate the valve stems there may be substituted lever handle
mechanism and a quadrant piece for operating the valve by means of cam surfaces
say on the outer edge thereof.

Improvements in Apparatus for Operating Valves for Controlling
the Passage of Fluids.
I, HERBERT TROTT, of 75, High Street, Battersea, in the County of Surrey,
Engineer, 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:-
This invention relates to means or apparatus for operating the valves employed
for controlling the passage of fluids and particularly the control of the passage of
water in baths or wash houses.
In carrying out my invention I employ say two valves of the description indi-
cated by me in the Specification of Letters Patent No. 15275 dated 9th November
1887 or other suitable form of valve to be either drawn or pressed to and from

page_text: their seats for opening or closing and the two valves may have their valve pieces
respectively drawn to their seats by means of springs acting on the stems of the
valve pieces so as to give them a constant tendency to close to their seats. Ou the
outer ends of the stems are anti-friction wheels which come in contact with a
circular rotatory. plate actuated by a hinged handle or by a suitable lever or
operating part. This rotatory plate is formed with rises depressions or other equi-
valent can surfaces so that as it is rotated the valve stems are pressed partly in,
wholly in, or left wholly out so as to partly open, wholly open, or leave closed one
or both valves at one time the cam surfaces being arranged so that one valve say
the cold water valve may by a movement of a quarter turn of the handle plate be
opened or by a like quarter turn in the opposite direction the other valve may be
opened instead-say for hot water-whilst by a half turn in either direction both
valves may be opened and both temperatures admitted at once. By another move-
ment of the handle on its hinge connecting it to the rotatory plate when the valves
are off and the handle at zero the waste plug may be raised from its seat and the
water previously supplied run off.
The same results may be attained by a modification in which for a rotatory plate
with cam surfaces to operate the valve stems there may be substituted lever handle
mechanism and a quadrant piece for operating the valves by means of cam surfaces
say on the outer edge thereof.

Fig. 18 shews by a sectional front view and Fig. 19 by plan view a modification in
which means for operating alternatively the pair of valves is provided, the alternative
motionsto the respectivevalve spindles being attained bymeans of cam surfaces arranged
on a parallel bar capable of being slidden horizontally by means of rack teeth h¹,
in which gear teeth formed on the surface of a pinion g mounted on the axis of the
}

page_text: operating plate b which is capable of rotation to the desired extent so as to produce
the desired extent of opening or closing of the respective valves.
Fig. 20 shews a front view and Fig. 21 a plan view of another modification of
the apparatus in which the movement of the valve spindles is effected by means of
tooth gearing, but in this case the teeth are arranged around a disk or wheel instead
of on a plane surface.

:
Fig. 24 shews by a sectional view an arrangement of the apparatus substantially
as shewn by Fig. 15 adapted especially to a bath. Fig. 25 shews a front view of a
portion of the apparatus shewn by Fig. 24.
Fig. 26 shews by a vertical section Fig. 27 by a front view with the enclosing
plate removed and Fig.28 by front view with the enclosing plate in its place an adapta-
tion of the arrangement described in respect of Figs. 20 & 21, but with the omission of
the rack teeth on the edge of the operating plate and of the pinion operating the same.
In the present arrangement the operating plate is moved by means of a handle, thie
point of which is inserted in a hole formed in the periphery of the operating
plate but so that the said handle may be removed by the attendant so as to prevent
illicit interference with the valve" arrangements, and particularly adapted fór
asylums and public or other institutions.
Fig. 29 shews a modification in the arrangements for attaining the cam motion to
the two valve spindles operating the respective valves, especially adapted for use
in valves, controlling the supply of liquid under high pressures, and designed to
admit of one valve being open to a much slighter extent than the other, and so as
more readily to control the pressure of the fluid.
Fig. 29 shews a detail view indicating the operating cam r and the cam pulley d
on the end of the spindle d.
Fig. 30 shews by side view and Fig. 31 by plan view a modification of the
arrangement shewn by Fig. 29. the motion for controlling the respective valves
being attained by inclines formed on the inner face of a disk capable of rotation in
a direction at right angles to the line of movement of the valve spindles, somewhat
similar in manner to the arrangement shewn in Fig. 1.
Fig. 32 shews an inner face view of the cam plate attached to the lever of the
ball valve shewn in the preceding figures.
In Fig. 33 is shewn a modification of a mode of attaining the respective
movements by means of a rotatory plate attached to the lever of the ball and
traversing a screw in manner substantially as indicated in respect of Fig. 9.
Fig. 34 shews a modification in a detail for operating the waste valve especially
adapted for arrangements of bath apparatus, such as indicated by Figs. 15 & 16.
In this case instead of rocking the indicating handle, a stud of a rod passing
there-through may be operated which draws upon a crank arm carrying a segment
to which is attached a chain connected to the rod of the waste valve to raise it as
will be more fully described.
In the arrangement of apparatus shewn by Figs. 1 to 8 a is the operating
plate formed with a sleeve a' (see Fig. 4) through which passes a stem on which
is mounted the index plate b, and on this stem is formed the screw 62 (Fig. 5)
which is passed or screwed into the opening provided for it (Fig. 8) in the body
of the valve c and locked therein by means of the lock nut 13, (Fig. 7) a² are
springs retained in recesses formed for them in the plate a and bearing against the
index plate to provide frictional tension between them to prevent slipping. The
plate a is rotated by means of the handle and indicating lever a³. On the inner
surface of the plate a are formed the inclines or cam surfaces a as against which
press the pullies mounted on the ends of the spindles d which operate the valves.
These valve spindles d are formed with two diameters, the smaller diameter being
encircled by the spring having its abutment at one end on the collar d³ of the
spindle & and at the other on a collar working against the cone packing piece №³

page_text: closing the spring chamber from the valve passage c¹ formed in the body of the
valve c.
The end of the valve spindle d is formed with an enlargement which takes into a
groove or clips formed on the valve-piece e which valve-piece is suspended from and
slides on ears or lugs el supported on ledges in the valve case. is a screw cap
or stopper closing an opening by which the valve-piece c is accessible for removal or
examination.
By the rotation of the operating plate a to a greater or less extent on its central
axis the inclines or cam surfaces a are caused to press in or out more or less the
respective valve stems d and so open more or less the valve passages to admit of
the inlet of hot or cold water through those passages, whilst in its midway position
they will both be closed. This will be seen by reference to Fig. 2 where the
handle lever is shewn in the position of "off" or midway with both valves closed.
By turning the handle a certain distance, say to the point marked cold" the
one valve will be opened admitting cold water whilst the other valve controlling
the hot supply will remain at rest. By further turning the handle in the same
direction it may be moved so that whilst the "cold" valve is still open the "
valve also is opened causing the supply to be tepid.
66
hot":
By turning the handle in the reverse direction say to the point marked "hot"
whilst the cold" valve has been allowed to close the hot water valve is opened
and by a further movement hot and cold again may be allowed to enter.
The
detail view Fig. 3 indicates the inner face and arrangement of the inclines a¹ a
Fig. 6 indicates the opposite or outer surface of the operating plate «, and the
location of the friction springs a².
In Fig. 9 the respective movements to the valve stems are attained by means of a
rotatory plate a operated by a handle a which may project in line with the face of
the plate or at right angles thereto as indicated by dotted lines. This plate has a
central sleeve a' which is threaded and rotates on a corresponding screw thread
formed on a stem mounted on the stem 7 mounted on the body of the valve.
the arrangement shewn the valves are designed so that the movement of the
plate a will cause the one valve to be first opened and then the other valve so as to
allow first of the ingress of the hot water and then of the cold water to modify the
degree of heat or vice versa.
In
In Fig. 10 the two valves are shewn at zero or both closed but by rocking the
handle on its centre a the arms a a³ will press on one or other of the pullies on
the ends of the valve stems & so as to open or close one or other valve and allow of
the entrance of hot or cold water or otherwise as desired, whilst tilting at right
angle to the motion to open or close a single valve opens or closes both valves.
In Figs. 13 and 14 the cam surfaces a a are formed on the interior surface of
the circular part barrel a mounted on the axis 61 and these cam surfaces at a³
operate the pulley d mounted on the end of the valve stem d and so cause it to be
more or less pressed in so as more or less to open or close the valve controlling the
supply of hot or cold water. In the position shewn both valves will be closed.
By drawing the handle a³ in the direction of the arrow a short distance so as to
bring one of certain indications that may be made on the outer surface of the
barrel a in line with a pointer as f one valve may be opened supplying hot water
whilst by a further movement both valves may be opened-supplying-a-mixture of
hot-and-cold-water; and by a reverse movement of the barrel the valve containing
the cold water alone may be operated.
In Figs. 15 & 16 is shewn an arrangement in which is coupled with the
operating plate and indications for regulating the supply of the hot and cold or
hot or cold water, a device, by which the waste may be opened but only when
the hot and cold supply are off so that running away of the main supply to waste
is prevented.
In Fig. 15 this device is constituted by the adaptation of the handle otherwise
used to rotate the rotating plate for the purpose of giving movement to an arm
which lifts the waste valve rod. The handle a when the waste is to be operated

page_text: is tilted forward through a slot a cut in the operating plate coincident with the
point "off," so that when both valves are off this handle can be operated by tilting
forward, and in tilting forward it raises the lever a carrying the antifriction
pulley which rising raises the arm a attached to the rod as riding in the
bearing a and lifting or operating the waste valve, forming interlocking
mechanism to prevent illicit use of the waste.
By this means any accidental leaving open of the waste during ingress of hot or
cold water is prevented, or malicious or other waste of water.
an axis.
Fig. 17 shews an arrangement of the operating plate in combination with an
outlet flexible tube and rose for distribution of liquid either hot, cold or tepid.
In Fig. 18 b is an indicating plate g is a toothed pinion mounted on
central of the plate b; this pinion is rotated by a removable handle the squared
end of which is inserted in a squared hole formed in the axis of that pinion by
which it is rotated, and. in its rotation it gives movement to and fro to a toothed
rack formed on the part h. On the opposite side of this part are formed
inclines h h and h³ which correspond in their operations to the inclines a a³ of the
preceding figures. Thus when the pinion g and its pointer g' are rotated so as to
come opposite indications which may represent hot, cold or tepid displayed around
the circumference of the plate the part h will be moved so that the inclines h³
or operating on the pulleys d' of valve spindles operating a pair or other
number of valves controlling the supply of hot or cold water will regulate the
supply accordingly.
In Figs. 20, 21 and 22 instead of the toothed wheel y being mounted centrally
on the indicating plate it is mounted at the side thereof and its teeth engage
corresponding teeth a¹s formed around the periphery of the operating plate a so as
to cause that plate a to rotate to the desired extent and this plate is mounted on a
central axis b¹.
On the inner surface of this operating plate are formed the cam surfaces a* a
indicated by dotted lines in Fig. 22 substantially corresponding to the cam courses
shewn in Fig. 1. The axis on which the toothed wheel g is mounted is carried by
a projection from the body of the valve and the spindle is kept tight by means of a
spring interposed between the socket for the axis and the plate g. This plate g
is secured to the stem by a pin g*. In this arrangement facility is afforded by
the attendant of say a lunatic asylum or other institution to remove the handle or
operating means for the valves so as to prevent illicit interference with the supply.
Another advantage attendant on this arrangement is that of imparting a regular
and steady movement to the valve, concussion being prevented.
In Fig. 23 this last arrangement is shewn slightly modified and adapted to bath
supply and ii shewing two alternative forms for operating the wheel g, and the
inlets to the valves k 7 may be arranged at the side and the outlet arranged
centrally.
In Figs. 24 and 25 the arrangements indicated by Figs. 15 and 16 are here
shewn applied to a bath supply, the dotted lines a³ indicating the closed position of
the waste, whilst the full lines indicate it in the open position with the waste
valve n raised so as to allow of the water running away. indicates the joint
inlet for the water from the "hot"
"
and cold valves, and arranged at the top of
the bath, but it may be arranged to be supplied as shewn by the dotted lines or
at the bottom by means of a pipe as indicated by the dotted lines which would
supply the water to pass into the bath through the same inlet o as serves for
the outlet.
In Figs. 26, 27 & 28 the controlling apparatus is arranged within a casing, the
front of which is removable as shewn in Fig. 27 for access to the mechanism.
Referring to Figs. 26, 27 and 28 the operating plate is rotated by a removable
handle inserted into a hole, as p, which rotates that part and with it the cam
surfaces operating the apparatus as already described.
In Fig. 29 is shewn an arrangement of duplex valves e e adapted to be operated
by their spindles d d being operated upon by cam surfaces rr mounted
on an

page_text: axis and carried by a forked lever ² which lever also carries the ball. As the
water enters the reservoir and the ball rises it rotates the cams r and these cams
press on the ends of the rods d and so effect opening of the valves c, but these cams
are so arranged that the one valve is opened slightly in advance of the other so as
to remove the pressure of the fluid thereon, and in the reverse movement
of the ball and cams the valves e, e will correspondingly be closed one slightly
in advance of the other, assisting the closing especially against high pressures.
in
Figs. 30, 31, and 32 shew another arrangement for like purposes and operating
in substantially the same manner, except that in place of the cam shewn
Fig. 29 the cam surfaces are arranged around the inner surface of a rotating
disc or operating plate a much as described with reference to Fig. 1 and the rotation
of this plate a is effected by the ball operating the lever attached to that
plate a.
In Fig. 33 in place of anti-friction pulleys on the end of the stems being
operated directly by cam surfaces to open or close first one and then the other
valve, the valves are opened and closed by means of a rotatory plate a operated by
the lever and ball being caused to approach nearer to and to retreat from
those pulleys as it is rotated on the screwed central stem 61 substantially as already
described in respect of Fig. 9.
In Fig. 34 is shewn a modification in the manner of operating the waste valve
from that shewn by Figs. 15, & 16 in that instead of rocking the handle lever a³
forwards the knobs is as shewn drawn forwards drawing forward the rod and
with it the hook end which engages the arm t formed on the quadrant t¹ mounted
on the centre and connected by the chain to the waste valve rod a¹³, this
hook is only in position to engage the rod t when the indicating handle a³ is at
zero and both valves are "off" and the supply closed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In apparatus for operating valves for controlling the passage of fluids.
1. The combination, or arrangement, of two, or more, valves controlling two, or
more, supply passages for fluid, each valve separately, or two, or more, of such
valves together, being capable of operation by one controlling part, the extent of
movement of which part is indicated substantially as and for the purpose herein-
before set forth.
2. The combination or arrangement of two, or more, valves controlling two, or
more, separate pipes of supply and capable of being controlled by the movement of
one part to a greater, or less, extent so as to open either one valve separately, or
two, or more together; coupled with means for operating the waste valve so that
the waste valve can only be operated when the supply valves are in their closed
position, substantially as and for the purposes herein before set forth.
3. The combination or arrangement and use of parts of apparatus operating
substantially as set forth in respect of Figs. 1, 2, 3, 4, 5, 6, 7, 8, 13 and 14.
4. The combination or arrangement and use of parts constructed and operating
substantially as indicated by Fig. 9.
5. Two or more valves operating separate sources of supply controlled by one
rotating part so as to enable one or more of such valves to be opened or closed at a
time, coupled with mechanism controlling the opening of the waste pipe so
arranged that such waste pipe can only be opened when the sources of supply
are closed, substantially as shewn and described in respect of Figs. 15, 16, 24, 25
and 34.
6. The combination or arrangement and use with two or more inlet passages and
controlling valves thereto of parts for regulating the movements of the said valves
together or independently by means of one operating part so as to enable one or
more of the valves to be opened, partly opened or closed substantially as and
for the purposes set forth in respect of Figs. 18, 19, 20, 21, 22, and 23.

page_text: 7. The various arrangement or combinations of parts for opening one or more of
a set or series of valves in advance one of another by means of inclines or cams and
of closing them in like manner substantially as set forth in respect of Figs. 29, 29*
30, 31, 32, and 33.
S. The general arrangement or combination of the parts of apparatus as and for
the purposes herein before set forth.
