Improvements in Mechanism or Arrangements for Governing ՂԵ
Speed of Steam and other Motive Engines.
We, SAMUEL BUCKLEY, and JAMES TAYLOR of Castle Iron Works, Oldham in the
County of Lancaster, Engineers, do hereby declare the nature of the said invention to
be as follows:-
Our invention is more particularly intended for governing the speed of steam
Engines by acting upon arrangements of mechanism for varying the "cut off" of the
steam at each stroke according to the speed of the Engine, that is, cutting off the
steam at an earlier part of the stroke, if the speed increases and at a later part of the
stroke if the speed diminishes.
But our invention is also applicable for acting upon the throttle or other valve or
valves of steam or other motive engines such as water wheels and Turbines the speed
of which is governed and can be varied by varying the quantity of motive fluid
supplied to the engine, in a given time, but our invention is not applicable to
marine or other motive Engines, where the Engine is subject to oscillations.
We employ the ordinary centrifugal ball governor or any other governor acted upon
by a varying speed of rotation, and convey the motion from the governor, which
results from the varying rotary velocities, by an adjustable rod or other suitable
connection to a lever on a fulcrum on the framing of the Engine-This lever is a
trough and in it a metal ball, disc or cylinder is placed so that it can roll freely to and
fro from end to end of the trough lever, the trough serving to guide the ball or its
equivalent and keep it central over the imiddle of another lever, which may be a T or
three armed lever which T lever has its fulcrum on the same fulcrum pin or axis as the
trough lever, the T lever oscillating clear and freely through a slot made for it in the
bottom of the trough lever.
One arm of the T lever or its equivalent forms a clutch fork arm and spans a boss on
a shaft in suitable bearings which boss can slide endways on the shaft on a fixed key
so that the boss and shaft will rotate together-Each end of the boss has one part of a
friction or toothed clutch formed upon it to correspond with the other part of a friction

page_text: or toothed clutch on the boss of two bevel wheels free to rotate but not to move end-
ways on the said shaft. These two bevel wheels gear with a bevel wheel constantly
rotated by connection with the Engine, so that the two bevel wheels are driven in
reverse directions, and the shaft is rotated one way or the other according to the
clutch which is brought into gear, and when neither clutch is in gear the shaft
remains stationary.
The said shaft gives motion to a screw that operates upon mechanism which alters
the position of cams that actuate the steam valves of the Engine.
When the Engine is working at the desired speed the connection between the
governor and the lever trough is adjusted to bring it into a level position when the
ball will stand in the central part of the lever trough over its axis and both clutches
will be out of gear, but should the speed of the Engine increase the trough lever will
be moved by the governor and the ball will roll to one side of the trough, and depress
the corresponding arm (over which it rolls) of the three armed lever and this will bring
one of the clutches in gear to act upon the cut off accordingly.
Should the speed of the Engine decrease the inclination of the trough lever will be re-
versed and the ball will roll to the other extreme and bring the other clutch in gear and
so on. After the ball has moved in the trough lever, the governor is free to move
further in the same direction in consequence of a further increase or decrease of speed
without restraint by the ball or lever trough.
The levers and clutch mechanism and gearing may be varied according to the
purpose and the arrangement of the engine to which our governing mechanism is to
be applied, as it may be arranged to act as above described upon cut off gear, or so as
to open and close a valve or valves for increasing and decreasing the supply of motive
fluids to Engines to be governed.

We SAMUEL BUCKLEY and JAMES TAYLOR of Castle Iron Works, Oldham, in the
County of Lancaster, 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 is more particularly intended for governing the speed of steam
Engines by acting upon arrangements of mechanism for varying the cut off of the
steam at each stroke according to the speed of the Engine, that is cutting off the steam
at an earlier part of the stroke, if the speed increases and at a later part of the stroke
if the speed diminishes.
But our invention is also applicable for acting upon the throttle or other valve or
valves of steam or other motive engines such as water wheels and Turbines the speed
of which is governed and can be varied by varying the quantity of motive fluid supplied
to the engine in a given time but our invention is not applicable to marine or other
motive Engines, where the Engine is subject to oscillations.
We employ the ordinary centrifugal ball governor or any other governor acted
upon by a varying speed of rotations and convey the motion due to the rise and fall
of the balls from the governor, which results from the varying rotary velocities, by an
adjustable rod or other suitable connection to a lever on a fulcrum on the framing of
the Engine.
This lever is a trough and in it a metal ball, dise or cylinder is placed so that it can
roll freely to and fro from end to end of the trough lever, the trough serving to guide
the ball or its equivalent and keep it central over the middle of another lever which
may be a T or three armed lever, which T lever has its fulcrum in the same fulcrum
pin or axis (or another corresponding thereto) as the trough lever, the Ṭ lever
oscillating clear and freely through a slot made for it in the bottom of the trough lever.
One arm of the T lever or its equivalent forms a clutch fork arm and spans a boss
on a shaft on suitable bearings which boss can slide endways the shaft on a fixed key
so that the boss and shaft will rotate together-Each end of the boss has one part of a
friction or toothed clutch formed upon it to correspond with the other part of a friction
or toothed clutch on the boss of two bevel wheels free to rotate, but not to move end-
ways on the said shaft.
These two bevel wheels gear with a bevel wheel constantly rotated by connection
with the Engine so that the two bevel wheels are driven in reverse directions, and the
shaft is rotated one way or the other according to the clutch which is brought into
gear, and when neither clutch is in gear the shaft remains stationary.
The said shaft gives motion to a screw that operates upon mechanism which alters
the position of cams that actuate the steam valves of the Engine.
When the Engine is working at the desired speed the connection between the
governor and the lever trough is adjusted to bring it into a level position when the ball
will stand in the central part of the lover trough over its axis and both clutches will be
out of gear, but should the speed of the Engine increase the trough lever will be moved

page_text: by the governor and the ball will roll to one end of the trough, and depress the
corresponding arm (over which it rolls) of the three armed lever and this will bring
one of the clutches in gear to act upon the "cut off" accordingly.
Should the speed of the Engine decrease the inclination of the trough lever will be
reversed and the ball will roll to the other extreme and bring the other clutch in gear
and so on After the ball has moved in the trough lever, the governor is free to move
further in the same direction in consequence of a further increase or decrease of speed
without restraint by the ball or lever trough.
The bars and clutch mechanism and gearing may be varied according to the purpose
and the arrangement of the engine to which our governing mechanism is to be applied,
as it may be arranged to act as above described upon "cut off" gear, or so as to open
and close a valve or valves for increasing and decreasing the supply of motive fluids
to Engines to be governed.
Fig. 1 is an, elevation, and fig. 2 is a plan view illustrating our invention for
governing the speed of a Steam Engine by varying the position of the valve for cutting
off the supply of steam to the cylinder at an earlier or later part of the stroke
accordingly as the speed increases or decreases.
The governor is not shown-It is of the ordinary construction and its sliding sleeve
is connected with one end of a clutch fork lever, having its fulcrum on an arm or
bracket from the pillar holding the bearings of the governor shaft, the other end of the
said lever has one end of a rod jointed to it, this rod being formed in two parts
connected by a right and left handed screw coupling for shortening and lengthening
the connection, in the ordinary manner.
a is part of the pillar carrying the Governor shaft b, and c part of the adjustable
connecting rods from the said lever, the lower end of which rod c is jointed with one
end of a beam lever trough d having trunnions d¹ one on each side forming its fulcrum
which trunnions have their bearings in a stand from the framing.
Within the trough d of the lever, a ball d², is placed which is free to roll from end
to end along the bottom of the trough.
A cylinder may be used in place of the ball if desired.
There is a slot in the bottom of the trough d in its lengthway and within and clear
of the sides of the slot a T lever d³ is placed on a fulcrum formed by a pin d passing
through the hollow trunnions d¹ of the beam trough lever d.
The cross arm of the T lever extends in the lengthway of the trough lever d and its
upper surface is on a level with the inner bottom of the trough lever, the vertical arm
of the T lever d³ is forked to act upon a boss forming a double cone clutch ³ which
boss is upon a fixed key on a shaft e, in suitable bearings on the framing.
The cone clutch do can slide freely upon the shaft e but can only rotate with it.
Each end of the clutch boss d³ is formed with a cone cavity to correspond with a
cone on the boss of a bevel wheel.
There are two bevel wheels on the shaft e and the bosses of the wheels are arranged
to rotate in bearings on the framing but not to move end ways.
The two bevel wheels de and d' are in gear with another bevel wheel fl on a shaft f
in suitable bearings on the framing which shaft is driven by bevel wheels from a
horizontal cross shaft g which drives the vertical shaft of the governor by bevel
wheels.
It will be seen that the two bevel wheels do and d' on the shaft e are rotated in
opposite directions, and when the cone clutch d³ is brought into gear with the cone on
the boss of one bevel wheel, the shaft e will be rotated one way and when the cone
clutch is brought into gear with the cone on the boss of the other bevel wheel the
rotation of the shaft e will be reversed.
The shafte has a bevel pinion e¹ at one end which gears with a wheel h¹ on
one end of a vertical screw shaft in suitable bearings on the framing.
The screw shaft h has a screw nut 2 upon it with pivots which enter slots in
a forked arm ³ from a boss h which can oscillate on a shaft i in suitable bearings
on the framing.
The boss with the forked arm ³ has another arm that forms a stud for a

page_text: bevel wheel to rotate upon, which bevel wheel gears with two other bevel wheels,
one fast on the shaft and the other fast on a hollow or tubular shaft j in
suitable bearings on the framing through which hollow shaft the shaft i passes.
j
The other end of this hollow shaft has a spur wheel upon it that is driven
by a spur wheel g' on the end of the shaft g which last named spur wheel g¹ has
a bevel wheel on its disc face which is driven by a spur pinion 93 on a shaft h
receiving rotation by being geared with the crank or fly wheel shaft of the Engine.
Upon the shaft the cam is fixed for actuating the cut off valve, this cam
acting upon bowls in a dovetail slide which works in slideways formed in the
base plate framing and to this slide the rod is connected which gives motion
to the cut off valve.
It will be seen that the bevel wheel is driven by the bevel j¹ and that the bevel
wheel drives the bevel wheel ¹ fast on the shaft i.
It will also be understood that if the bevel wheel 6 is oscillated one way or the other,
this by causing the shaft to rotate more or less changes the position of the cam 2 in
relation to the crank of the Engine, that is to say, if the bevel 6 is oscillated
one way the cam is advanced to cut off sooner, if oscillated the other way the
cam is brought backwards and thus cuts off the steam to the cylinder at a later
part of the stroke.
When the Engine is working at the desired speed, the rod c is adjusted by the
screw coupling c¹ to bring the inside bottom of the trough lever d level, so that
the ball or cylinder d² will stand in the central position as shown in fig. 1, the
T lever d³ will then not be acted upon and the cone clutch d³ will be clear of the
cones on the bosses of both bevel wheels do and d but if the speed of the Engine
increases the trough lever d will be oscillated accordingly and the ball d² will roll
to one end, and its weight will depress the arm of the T lever d³ at that end of
the trough and force and hold the corresponding clutch in gear, this will cause
the shafts e and h to be rotated and the forked arm h³ of the boss to be moved
by the screw accordingly.
If the speed of the Engine decreases, the ball or cylinder d² will move to the
other end of the trough lever d and the other cone clutch d will be brought into
gear, which will reverse the movement of the forked arm ³ accordingly.
When the beam lever d has oscillated to bring the ball d² to one end and begins
to oscillate the reverse way the ball is lifted from the arm of the T lever d³ and
this allows the cone clutch to go out of gear.
It will be obvious that motion may be transmitted from the screw nut /² or
screw shaft to act upon a throttle valve or upon valves for supplying the motive
fluid to Turbines or water wheels or other motive Engines.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is.
1. The combination with a governor of a beam trough lever or its equivalent, a
T lever or its equivalent, a rolling ball or cylinder and clutch mechanism for
governing the speed of steam or other motive Engines substantially as hereinbefore
described and illustrated by the drawings.
2. The combination and arrangement of mechanism for governing the speed of steam
Engines by acting upon the cut off valve mechanism substantially as hereinbefore
described and illustrated by the drawings.
