CHARLES THOMAS BULLOUGH 6 Meads Row Lambeth Surrey Engine Fitter do
hereby declare the nature of my invention for IMPROVEMENTS IN APPARATUS FOR
REGULATING THE SUPPLY OF STEAM TO MARINE STATIONARY & OTHER MOTOR
ENGINES to be as follows:-
This invention has reference to an apparatus which I call a governor for
regulating the speed of Steam Engines or other motors. It consists of a spindle
which I call the vane spindle, revolved from the motor to be regulated, to which
are fixed a number of moveable vanes-the vanes being enclosed in a cylindrical
casing filled with a liquid. These vanes are so arranged that they fly out or close
up as the speed of the vane spindle increases or decreases, the movement of these
vanes turns a hollow spindle which I call the disc spindle & which is fitted outside
the vane spindle by means of a horizontal disc with suitable slots & pins enclosed
in the vane casing. The vane spindle is attached to a box containing a helical
spring one end of which is fixed to & wound round the disc spindle, so that the
spring offers a resistance to the movement of the disc spindle. The spring can be
adjusted to any tension by means of a ring (which I call the adjusting ring & other
suitable connections outside the spring box. The movement of the disc spindle is
made to give a rectilinear movement to another disc which I call the regulator
disc by means of a curved & straight slot & pin connection.
This regulator disc by its movement gives a movement to what I call the
regulating lever which is connected to the end of a valve spindle working an
ordinary slide valve on a small adjacent cylinder. This cylinder contains a piston
& piston rod, the latter being connected to the supply or regulating valve of the
driving motor, so that when the regulating lever fitted to the regulating disc on
the disc spindle moves through the flying out or closing up of the vanes, movement
is given to the cylinder slide valve so that steam is admitted to the sinall cylinder
which acting on its pistons opens or shuts the supply or regulating valve of the
driving motor & so governs the speed of this motor.
This apparatus or governor is not dependant in its action upon any particular
arrangement or position of its parts.

I CHARLES THOMAS BULLOUGH 6 Meads Row Lambeth Engine Fitter do hereby
declare the nature of my invention for IMPROVEMENTS IN APPARATUS FOR REGU-
LATING THE SUPPLY OF STEAM TO MARINE, STATIONARY AND OTHER MOTOR
ENGINES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference being had
to the accompanying drawings:-
Fig. 1 Elevation and plan partly in section of my improved apparatus.
Figs. 2 and 3 show the vanes when thrown out and closed up respectively.
Figs. 4 and 4b show position of pin in slot in disc spindle when the vanes are
thrown out or closed up as shown in Figs. 2 and 3.
This Invention has referenco to an apparatus which I call a governor for
regulating the speed of steam engines and other motors. It consists of a spindle 2
which I call the vane spindle revolved from the motor to be regulated to which
are fixed a number of moveable vanes 1, the vanes being enclosed in a cylindrical
casing filled with a liquid.
These vanes 1 are so arranged that they fly out or close up as the speed of the
vane spindle 2 increases or decreases; the movement of these vanes 1 turns a
hollow spindle 3 which I call the disc spindle and which is fitted outside the vane
spindle 2 by means of a horizontal disc 3* with suitable slots 8 and pins 9 enclosed
in the vane casing.
The vane spindle 2 is attached to a box containing preferably a helical spring S
one end of which is fixed to and wound round the disc spindle 3 30 that the spring
offers a resistance to the movement of the disc spindle 3. The spring S can be
adjusted to any tension by means of a ring 6 (which I call the adjusting ring) and
other suitable connections outside the spring box 7. The movement of the disc
spindle 3 is made to give a rectilinear movement to another disc which I call the
regulator disc 41 by means of a curved and straight slot and pin connection 4.
This regulator disc 41 by its movement gives a movement to what I call the
regulating lever 5 which is connected to the end of the valve spindle working an
ordinary slide valve in a small adjacent cylinder Y. This cylinder Y contains a
piston and piston rod the latter being connected to the supply or regulating valve
of the driving motor so that when the regulating lever 5 fitted to the regulating
disc 4 on the disc spindle 2 moves through the flying out or closing up of the
vanes 1, movement is given to the cylinder slide valve so that steam is admitted
to the small cylinder which acting on its pistons opens or shuts the supply or
regulating valve of the driving motor and so governs the speed of this motor.

page_text: The action of this arrangement is as follows:-From the motor to be governed
a band is passed over pulley X which is attached to the vane casing 6 in which
the vanes I are enclosed said vanes 1 being attached to boss 2 having a feather
(shown in dotted lines) to prevent said boss 2 from revolving, the spindle 3 being
held by pin 7 working in the groove 7¹ also in the boss of the spring box 5 and in
the disc spindle 4.
'
The spring S is wound round and attached to the disc spindle 4 also to the
regulating ring 8*. The flying out or closing up of the vanes 1 turns the disc
spindle and so drives the pin 7 working in the grooves 7' to the other end of the
grooves 71 which causes the spring box 5 to partly turn as shown at a and a¹ Fig. 7.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1. The improved governor constructed and arranged in manner substantially as
shown in the drawings and as hereinbefore described.
2. The vanes and parts arranged as shown and for the purpose hereinbefore set
forth and described.
