PROVISIONAL SPECIFICATION.
Improvements in the Construction of Governors for Regulating the
Speed of Steam or other Motive Power Engines.
I JOHN WILD of Falcon Iron Works Falcon Street Oldham in the County of
Lancaster, Mechanical Engineer, do hereby declare the nature of this invention to be
as follows:-
Now the object of this invention is to produce governors that shall be more
sensitive and powerful than those in use at present and thereby secure a more
uniform speed of the motor governed than has been previously obtained.
To attain this a suitable standard is employed which supports a collared hollow
pillar. Below the collar and free to revolve on the pillar a block is placed to which
the driving gear may be attached and which is so constructed that the upper side of
the collar on the hollow pillar is below the upper surface of the block. On this block
two ears are formed through each of which a pin hole is bored.
On the upper end of the hollow pillar free to revolve and slide up or down a
threaded nut or bush is placed and upon this nut or bush a block is screwed having
ears similar to the block on the lower end of the hollow pillar and having a bush with an
internal flange at the top formed on the upper side of it.
At an equal distance between the centres of the pin holes in the ears of the upper
and the lower blocks and in the same plane two balls of a suitable size are placed
one on each side of the hollow pillar having holes of suitable diameters bored through
their centres.
Passing from the ball on one side of the hollow pillar to each of the ears on the
blocks of the opposite side of the hollow pillar pairs of arms are secured by means
of pins.
The distance between the centres of the holes in the said arms being determined
by taking the centres of the holes in the ears of either the top or bottom block and
measuring twice their distance or thereabouts as circumstances may require.
Between the nut or bush upon which the upper block is screwed and the lower
block a spiral spring is placed of such a strength as may be required by the velocity
and weight of the balls.
Now it will be seen that if the spiral spring be compressed by screwing the nut or
bush out of the top block a greater velocity of the balls will be required to compress
the spring and so secure the same movement of the top block as was obtained
previous to the spring being compressed by means of the said nut or bush.
A spindle is connected by suitable means to the internal flange of the bush formed
on the top block which may either pass down through the centre of the hollow pillar
to a valve to regulate the supply of motive power or otherwise as may be required.
When very steady running is required the spindle above mentioned is connected to
the central bevel of an ordinary friction reversing gear which by means of suitable
attachments will regulate the supply of motive power.

COMPLETE SPECIFICATION.
Improvements in the Construction of Governors for Regulating the
Speed of Steam or other Motive Power Engines.
I JOHN WILD, Falcon Iron Works Oldham in the County of Lancaster 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 improvements relate to that class of governors known as high speed 'governors

page_text: and such as may be arranged in combination with a throttle valve and caseing (or
otherwise as circumstances may require) for the purpose of regulating the supply of
steam or other motive power of the engine or machines to which such governors are
applied.
My invention consists essentially in improvements in governors hereinafter
described.
i
In the old style of governors the weights or balls as they are called have a greater
relative movement than the valve spindle consequently the increase or decrease in
the speed of the engine is considerable before the movement of the valve is sufficient
to decrease or increase the supply of motive power.
In order to remedy this and to make the governor more sensitive and prompt in
responding to any change of speed that may take place in the engine governed I
cross both the top and bottom pairs of arms so as to obtain a large movement of the
valve spindle for a small movement of the weights or balls consequently a small
variation in the speed of the engine will be immediately checked by a corresponding
movement of the valve which regulates the supply of motive power.
Instead of a central weight I employ a spiral spring which may be compressed or
released by a suitable means hereinafter described so as to vary the resistance it
offers thereby varying the speed of the engine.
In order that the speed of the engine may be varied whilst in motion I make a
screw thread upon the valve spindle or its equivalent so that it may be raised or
lowered by screwing through a loose ferrule hereinafter described.
When very steady running is required the valve spindle or its equivalent is
connected to the central bevel of an ordinary friction reversing gear which by
means of suitable attachments hereinafter described will regulate the supply of
motive power.
In order that my invention may be more readily understood I have annexed here-
unto two sheets of drawing Figs. 1 2 and 3 Sheet 1 and Figs. 1 and 2 Sheet 2 Fig. 1
Sheet 1 representing a sectional elevation Fig. 2 Sheet 1 an end elevation Fig. 3
Sheet 1 the plan. Figs. 1 and 2 Sheet 2 represent a sectional and end elevation
of my frictional arrangement which I apply when very steady running is required.
I will now proceed to describe my improvements illustrated by the before
mentioned drawings.
I employ a suitable standard N (whose base may or may not as circumstances
require form a throttle valve cover) supports the hollow pillar A below the collar a¹
and free to revolve on the hollow pillar A a block e is placed to which the driving
gear m may he attached and which is so constructed that the upper side of the
collar a¹ on the hollow pillar A is below the upper surface e² of the block e¹ on the
block e two ears and are formed through each of which a pinhole is bored.
On the upper end of the hollow pillar A free to revolve and slide up or down a
threaded nut or bush g is placed and upon this nut or bush g a block e is screwed
having ears and with holes bored through similar to the ears and on the
block e¹ and having a bush p with an internal flange 9 formed on the upper side
of it.
At an equal distance between the centres of the holes in which fit the pins l'
and 31 and 12 in the ears 15 and 114 and 1 of the blocks e and e¹ and in the same
plane two weights or balls c and c² of a suitable size are placed one on each side of
the hollow pillar A having holes to receive the pins 2 and 3 bored through the
centres. Passing from the ball c¹ to the ear on the block e¹ a pair of arms d' are
placed and passing from the earl on the block e¹ to the ball cl another pair of arms d
are placed and also the pair of arms d passing from the ball c to the ear on the
block e and passing from the ball c' to the ear a pair of arms d' are placed and each
pair of arms d d¹ d2 and d³ are connected at their ends to the ears 11 11 and Z and
to the balls c and c¹ by means of pins 16 17 1³ ³ and c³ which when secured in
position by means of nuts complete the link work.
5
The distance between the centres of the holes in the arms d d d and d³ for the
pins c² 32 and 13 being determined by taking the distance between the centres

page_text: of the pin holes 16 and 17 or 12 and 13 and measuring from two to two and one half
times that distance as circumstances may require.
Between the threaded nut or bush g upon which the block e is screwed and the
block el a spiral spring 6 is placed of such a strength as may be required by the
weight and velocity of the balls c and
By screwing the nut or bush out of the block e and thus compressing the
spring a greater velocity of the balls c and c¹ will be required to compress the
spring 6 thereby insuring a greater speed of the motor governed for the same
movement of the block e as was obtained previous to the spring being compressed
by means of the bush g.
The rod i is screwed into the ferrule ; and passes down through the hollow pillar A
to a valve which regulates the supply of motive power.
By unlocking the nut h the spindle i may be raised or lowered by screwing either
one way or the other through the ferrule j and so regulate the supply of
motive power.
When very steady running is required the gearing is employed to drive the
shaft t and with it the bevel friction. The rod i is then connected to the sleeve u
so that when the governor raises or lowers the rod i the bevel friction ³ is brought
in contact with the bevel friction or thereby causing them to revolve in one
direction or the other according as to whether the bevel friction is brought in
contact by the raising or lowering of the rod i with the bevel friction r or r¹ thereby
raising or lowering the screw s which may be connected either to the throttle valve
or cut off motion of the engine to be governed in any convenient way.
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-
1. The crossing of the bottom pairs of arms substantially and for the purpose
described and illustrated by the accompanying drawings.
2. The employment of a regulating nut or bush substantially and for the purpose
described and illustrated by the accompanying drawings.
3. The screwed spindle and lock-nut and ferrule substantially and for the purpose
described and illustrated by the accompanying drawings.
4. The employment of friction gear for the purpose and in the manner described
and illustrated by the accompanying drawings.
5. The general arrangement of governors for steam or other motive power engines
or any other colourable imitation thereof substantially as described and illustrated by
the accompanying drawings.
