Improvements in and relating to Apparatus for Regulating or
Controlling the Supply of Steam and other Fluids to Engines
or Motors, and for similar Purposes.
1, WILLIAM TULLY, of 47 Rounton Road, Campbell Road, Bow, in the County
of Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
:―
My invention relates to apparatus for regulating or controlling the flow of steami
and other fluids.
The main object of my said invention is to provide for utilizing the dynamic force
of the steam or other Huid for regulating or controlling the supply thereof to an
engine or motor. And my said invention affords efficient means for preventing
racing of marine and other engines.
An important feature of my said invention consists in the combination of a governor
or regulator and a stop-valve in such a manner that the supply of steam or other
fluid can be regulated or controlled by hand as required, and, should the speed of
the engine increase by reason of any sudden diminution of the work which it has to.
perform, the supply of steam or other fluid thereto will be automatically cut off by
the dynamic force of the fluid. The stop-valve is, in some instances, however,
constructed separately from the governor or regulator.
Another important feature of my said invention is the construction of the apparatus
in such a manner that the part which operates to cut off the supply of steam is
within the steam-pipe, the spring or other device for effecting the return movement
of the said part being arranged outside the said pipe so that it will not be subjected
to the action of the steam and can be readily adjusted. The said spring or other
device is provided with means for adjusting it to suit any desired working pressure.
Suitable means are moreover, provided for indicating or registering the pressure for
which the said spring or other device is adjusted.
My said invention is conveniently and advantageously carried into practice as
hereinafter described that is to say: A suitable valve is arranged within a part of
the steam-pipe which is provided with a seat for the said valve, and with guides in
which the valve-stem is fitted so that the valve and stem can slide longitudinally
towards and away from the said seat. The said valve is formed or fixed on one end
of the said stem and the other end of this stem is provided with a disc or head or
with a hollow cone or cup. The steam-pipe is provided with a contracted part of less
diameter than the said disc, head, or cup, so that, when the speed of the engine
suddenly increases, the steam passing through the said contracted part of the pipe
with great velocity will impinge against the said disc, head or cup and drive the said
valve to its seat.
The valve-stem is provided with rack-teeth with which is geared a toothed wheel
or segment fixed upon a shaft fitted in suitable bearings in a chamber or casing
formed on or attached to the steam-pipe. The said shaft may or may not extend
completely through the sides of the said chamber or casing. The said toothed wheel
or segment is formed with a slot in which works a pin or stud whereby a rod is
coupled to the said wheel or segment. This rod extends through a stuffing-box in
the top of the said chamber or casing and through a cross-bar fixed upon suitable
pillars or columns. A spring is arranged upon the said rod between a fixed collar
thereon and the said cross-bar. The upper end of the said rod is screw-threaded and
has fitted thereon a nut or screw-threaded sleeve arranged to rotate in the said
cross-bar and provided with a flange or collar which bears against the upper side of
the said cross-bar. The said nut or sleeve is moreover, provided with a hand-wheel

page_text: whereby it may be turned to raise the said rod or permit it to be moved downward
by the spring and thus effect the opening or closing of the valve by hand. When the
valve is automatically closed by the steam, the said spring is compressed and will
react, as soon as the speed of the engine is sufficiently diminished, and thus
automatically open the valve to any extent determined by the adjustment of the said
hand-wheel. The said rod is provided with an indicator to show the extent of
opening of the valve under normal conditions. I prefer to divide the pipe or casing
containing the valve longitudinally into two halves or parts which are firmly united
by bolts or otherwise. I thus facilitate the construction of the apparatus.
"I do not limit myself to the construction of apparatus. herein before particularly
described as the construction thereof may be modified in many ways without departing
from the nature of my said invention. For instance, the spring may, if desire.l, be
arranged within the pipe. Moreover I can use other means than those above
described for connecting the valve with the spring or for operating the said valve
by hand.
Although I have more particularly described my improvements as applied to the
regulation of the supply of fluid to an engine or motor, it is obvious that they are
also applicable in other cases where it is desired to regulate or control the flow of
steam or other fluid.

Improvements in and relating to Apparatus for Regulating or
Controlling the Supply of Steam and other Fluids to Engines
or Motors, and for similar Purposes.
1, WILLIAM TULLY, of 47 Rounton Road, Campbell Road, Bow, in the County of
Middlesex, 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 :-
:-
My invention relates to apparatus for regulating or controlling the flow of steam
and other fluids.
The main object of my said invention is to provide for utilizing the dynamic force
of the steam or other fluid for regulating or controlling the supply thereof to an
engine or motor, that is to say, for regulating or controlling the flow of the steam or
other fluid by the variations in the velocity of the same due to diminution or increase
of the work which has to be performed by the engine or motor. And my said
invention affords efficient means for preventing "racing" of marine and other
engines.
An important feature of my said invention is a combined governor or regulator
and stop-valve whereby the supply of steam or other fluid can be regulated or
controlled by hand as required, and, should the speed of the engine increase by
reason of any sudden diminution of the work which it has to perform, the supply of
steam or other fluid thereto will be automatically cut off or diminished by the closing
of the valve by the dynamic force of the fluid. This apparatus is so constructed that
the valve whereby the regulation or control of the flow of the fluid is automatically
effected, is also utilized for effecting such regulation or control by hand.
A spring or its equivalent is employed for effecting the return movement of the
valve and is provided with means for adjusting it to suit any desired working pressure.
Suitable means are also provided, if desired, for indicating the pressure for which
the said spring or other device is adjusted.
My said invention, moreover, comprises the adaptation of my apparatus for use
separately as a governor or regulator, and its adaptation for use separately as a
stop-valve.

page_text: My said invention also comprises other improvements hereinafter set forth.
In the accompanying drawings I have shown how my said invention may be
conveniently and advantageously carried into practice.

or modification of my apparatus.
Figure 11 is a vertical longitudinal central section illustrating a further modification
of the said apparatus, and
Figure 12 is a vertical longitudinal central section illustrating a still further
modification thereof.
Like letters indicate corresponding parts throughout the drawings.
A is a casing or chamber which is designed to form part of the supply pipe for
the steam or other fluid. In one end of this casing is fixed a valve-seat B. Cis the
valve, which is so arranged in the said casing that it can slide longitudinally to and
from the said seat B.
In the apparatus shown in Figures 1 and 2, the stem or spindle (of the valve C
extends through bearings or guides D formed or fixed in the casing A and provided
with removable caps to permit the withdrawal and replacement of the valve when
necessary. The said valve is formed or fixed on one end of the stem or spindle C¹
and the other end of this stem or spindle is provided with a hollow cone or cup E, or
it may be provided with a disc or head, or the cup may he reversed if desired. The
casing A is provided with a contracted part A¹ of less diameter than the said disc,
head or cup, so that, when the speed of the engine suddenly increases, the steam or
other fluid passing through the said contracted part of the pipe with great velocity
and impinging against the said disc, head or cup, will drive or force the said valve
towards its seat.
The valve-stem C' is provided with rack-teeth C with which is geared a toothed
segment F formed with a lever F pivoted at F2 to the casing A. The said lever is
provided with a slot F³ in which works a pin or stud G whereby a rod G is coupled
to the said lever. This rod extends through a stuffing-box A" in the top of the said
chamber or casing A and through a cross-bar H fixed upon suitable pillars or columns J.
A spring K is arranged upon the said rod between a fixed collar L thereon and the
said cross-bar H. The upper part of the said rod G is screw-threaded and has fitted
thereon an internally screw-threaded hand-wheel or nut M arranged to rotate on the
cross-bar H. This wheel or nut may be turned in one or the other direction to raise
the said rod or to permit it to be moved downward by the spring K.
I thus provide
for effecting the opening or closing of the valve by hand, and for regulating the
action of the said spring. A lock-nut N is provided for securing the hand-wheel or
nut M on the rod G in any desired position. The said rod G is provided with an
indicator or pointer O to show on a graduated scale on one of the columns J the
extent of opening of the valve under normal conditions. The case A is provided
with a cover A³ at one side thereof.
Instead of employing bearings or guides for the stem or spindle of the valve C, I

page_text: sometimes make the said valve with guides or feathers C³, Figure 3, fitted to slide
in,the,. valve-seat B, and I provide the cup E with guides E' fitted to slide in the
casing A.
When my apparatus is intended for use only as a governor or regulator, I can
simplify the construction of the same as shown in Figures 4, 5 and 6, that is to say,
I can arrange the whole of the working parts within the pipe or casing A. In the
modification of my invention shown in these figures, the spring K surrounds the
valve-stem Cand bears at one end against one of the guides I) and at its other end
against one of a pair of lock-nuts P, whereby the degree of compression of the said
spring may be varied as required and the action of the apparatus thus regulated or
determined. The guides D are formed separately from the casing A and without
caps, and are united by a bar or plate D', so that the valve and spring can be properly
fitted in the said guides and the whole then inserted in the said pipe or casing A
through one end thereof and secured therein in any convenient manner. The inlet
end of the casing A has an annular piece or disc A secured therein which can be
removed to permit the withdrawal of the guides D, the valve and the spring.
When my apparatus is intended to serve only as a stop-valve, I dispense with the
spring and the cup, disc or head on the valve-stem, and I substitute for the rack
and toothed segment above described, a lever F*, Figure 7, one arm of which extends
into a circumferential groove C3 in the valve-stem. the other arm being forked and
engaging with a screw-spindle G* extending through a stuffing-box A³ in the
casing A.
In the modification of my invention illustrated in Figures 8, 9 and 10, the toothed
segment F is fixed upon a spindle F which extends through a stuffing-box A² in
the casing A and which has fixed on its outer end a lever Q. This lever is acted
upon at its free end by a spring K provided with a screw K' for regulating its
tension. I sometimes provide a suitable clip so that the lever Qmay be operated
by hand to close the valve C and may then be held in position by the said clip. The
apparatus thus arranged is a combined governor and stop-valve.
In the modification of my invention illustrated in Figure 11, I provide for
permitting the passage of steam or other fluid through the valve when the latter
is closed, in order to facilitate the re-opening of the valve by the spring. For this
purpose I bore a hole longitudinally through the valve C and provide the same with
a relief valve R, the spindle R' of which extends through the valve C and is retained
therein by a nut or head R2. The spindle R and nut or head R2 are so shaped as
to permit the passage of steam through the valve C when the valve R is open. The
valve-seat B is provided with a bridge B₁ against which, when the valve C is closed,
the spindle R will strike; the said spindle will thereby he moved longitudinally and
the valve R thus opened. When the valve C is reopened, the valve R will be closed
by the fluid acting upon it.
I sometimes provide the valve-stem (with more than one cup or disc for the
fluid to act upon for the purpose of closing the valve C. Moreover, in some
instances, I form a cup at the back of the valve C.
In the modification of my invention shown in Figure 12, the inlet is at a right
angle to the main portion of the casing A, and the valve-stem C¹ extends through a
stuffing-box A in a cover A³, which is screwed into the casing A. The gland A
of the said stuffing-box is provided with a screw threaded extension A upon which
is fitted a screw-cap S. This screw-cap bears against a shoulder C on the spindle (³,
so, that, by turning the said cap in one or the other direction, the extent of opening
of the valve C can be regulated or determined. The spring K surrounds the
spindle between the said screw-cap and a pair of lock-nuts P screwed upon the
said spindle. The valve C has formed or fixed on the back thereof a cup E³, and
two other cups E, E² are formed or fixed on the spindle C, the cup E being of
slightly larger diameter than the cup E and of slightly smaller diameter than the
cup E The valve C is, moreover, provided with a short guide-rod or stem ( which
works in a hole in a bridge B¹ in the valve-seat B.
It will be seen that, in the different forms or modifications of my combined

page_text: governor and stop-valve above described, the valve C serves for the regulation or
control of the flow of the fluid by the dynamic force of the same, and also for effecting
such regulation or control by hand.
I do not confine myself to the use of a spring for keeping the valve C away from
its seat and effecting the return movement of the said valve after it has been moved
towards its seat. I can, if desired, use for this purpose one or more weights placed,
for example, on the rod G or on the lever Q. Moreover I can use means other than
those above described for connecting the valve with the spring or for operating the
said valve by hand.
Although I have more particularly described my improvements as applied to the
regulation of the supply of fluid to an engine or motor, it is obvious that they are
also applicable in other cases where it is desired to regulate or control the flow of
steam or other fluid. For instance, my improved apparatus may be used as a gas-
governor or for regulating the flow of water or other liquids. Moreover the valve
may be used in a vertical instead of a horizontal position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it understood that
I claim :-
First A valve fitted to slide longitudinally to and from its seat in a casing or pipe
and acted upon by a spring or its equivalent which keeps or tends to keep the said
valve away from its seat, and provided with one or more cups, discs or the like to
be acted upon by the dynamic force of the steam or other fluid, for the purpose
above specified.
Second The combination, with the said valve, the casing and the spring or its
equivalent, of suitable means for operating the said valve by hand and for regulating
the action of the said spring or its equivalent, substantially as, and for the purposes,
set forth.
Third A combined governor and stop-valve wherein the valve for automatically
effecting the regulation or control of the flow of the fluid is also utilized for effecting
such regulation or control by hand.
Fourth A governor comprising a valve having a spindle or stem provided with
one or more cups, discs or the like for the purpose above specified, and arranged to
slide longitudinally to and from its seat in a casing or pipe, and a spring also arranged
within the said casing or pipe and acting upon the said valve to keep it from its
seat, whilst permitting its movement towards the said seat by the dynamic force of
the fluid.
Fifth The improved stop-valve comprising the valve proper arranged to slide
longitudinally to and from its seat in the casing, and suitable means for operating
the said valve by hand, substantially as above set forth.
Sixth The provision of suitable means for permitting the passage of steam or
other fluid from one to the other side of the valve when the same is closed, for the
purpose above specified.
Seventh-The improved apparatus constructed substantially as described with
reference to Figures 1 and 2, or to Figures 4, 5 and 6, or to Figures 8, 9 and 10 or
to Figure 12 of the accompanying drawings and operating as, and for the purposes,
above specified.
