WILLIAM TAYLOR Watchmaker Union Street Coupar Angus Perthshire Scotland do
hereby declare the nature of this invention to be as follows:-
A vessel containing mercury or other fluid is attached to a vertical spindle which
revolves with the motor to be governed. The vessel is preferably of a more or less
conical shape, and with internally fixed vanes to facilitate the carrying round of the
fluid when the vessel revolves. At the centre a float rests on the fluid and is connected
by a lever or other gear with the throttle valve or other controlling mechanism of
the motor, in such a manner that when the float rises the power of the motor is
increased and when the float descends the power of the motor is diminished: The
float rises or falls as the speed of the motor diminishes or increases in consequence
of the vortical form which the revolving fluid takes under centrifugal force. The
float is held in place, with freedom to rise or fall, either by means of a central guide
on which it is free to slide, which may be the spindle continued upwards through the
cup; or by being attached to a hinged rod, which may be a lever connecting it with
the controlling mechanism.

I. WILLIAM TAYLOR, of Union Street, Coupar-Angus, in the County of Perthshire,
Scotland, Watchmaker, 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:—
A vessel containing mercury, or other fluid, is attached to a vertical spindle ;
which revolves with the motor to be governed.
The vessel is preferably of a more or less conical shape, and with internally fixed
vanes to facilitate the carrying round of the fluid, when the vessel revolves.
At the centre a float rests on the fluid, and is connected by a lever or other gear
with the throttle valve, or other controlling mechanism of the motor, in such a
manner that when the float rises the power of the motor is increased, and when the
float sinks, the power of the motor is diminished.
The float rises or falls as the speed of the motor diminishes or increases, in
consequence of the vortical form which the revolving fluid takes under centrifugal
force.
The float is held in place with freedom to rise or fall; by means of a central
guide on which it slides, which may be the spindle continued upwards through
the cup.
DESCRIPTION OF DRAWINGS.
Fig. 1. is a vertical section showing the float in its lowest position.
Fig. 2. a plan looking on the top, and
Fig. 3. a plan showing the vanes with the cover 17. and the float removed.
1. is the driving pulley firmly fixed to spindle 2.
3. is a screwed siieve within which the spindle 2. revolves.
4. is a friction pulley fixed to spindle 2. and 5. is another fixed to the slieve 6.
7. is a slot in slieve 3. for receiving the point of a set pin 8., and which is
intended to keep the slieve 3. from revolving when the nuts 9. or 10. are being
adjusted; when it is desired to move the spindle 2. and the friction pulley 4. nearer to,
or further from the vertical axis of slieve 6.
The purpose of this arrangement is to permit of the number of revolutions per
minute, of vertical slieve and coned cup, being varied.
Instead of using these friction pulleys, I may use ordinary bevel wheels instead ; in
which case the lateral adjustment of spindle may be dispensed with.
11. is the conical cup for containing the mercury 12., or other fluid; and may be
made of iron, iron enamelled, or glass.

page_text: Fixed to this cup are the vanes 13. 13. for the purpose of carrying round the fluid
with it.
14. is the float resting upon the top of the fluid and firmly secured at 15. to
rod 16.
16. is the connecting rod by means of which the throttle valve is actuated.
17. is the cover fitting air tight at 18. to conical cup 11. and descending into
same as shewn for the purpose of using as small a quantity of the fluid as possible.
The cover bears on the vanes so far as it extends; and thus keeps the fluid from
passing over into the adjacent chambers.
The cylindrical surface of the float 14., is kept clear of the cover 17. ; so that when
the conical cup with its cover is revolving, the float with its connecting rod 16. may
not do so, if desired.
19. 19. are communication holes between the annular space 20. and the inside of
the cover for the purpose of permitting the air which is above the mercury, to flow
into the space 21.
I may do away with these communication holes without any detriment to the
efficient working of the apparatus; the only effect being, that the air in the annular
space 20. will be compressed, instead of being allowed to flow into the space 21.
I may have either compressed air, carbonic acid gas (CO2); or may form a
vacuum within the space 20. and 21., although I do not specially claim this
modification.
The CO,, is for the purpose of preventing the mercury from oxidizing.
22. is a stuffing box for the purpose of excluding the air from the space 20.
23. shows the form of footstep I use for the slieve 6.
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 combination of a vertically moving float 14., with a coned cup 11., said
float being actuated by means of a fluid 12; the height of its surface supporting
the float being governed by the speed with which it is revolved, substantially as
described.
