Year: 1883

page_text: LETTERS PATENT to Joseph Whitley of Railway Works Leeds in the County
of York Engineer and Founder for an Invention of IMPROVEMENTS IN
THE CONSTRUCTION OF GOVERNORS FOR THE PURPOSE OF CONTROLLING AND
INDICATING THE SPEED AND POWER OF STEAM ENGINES AND FOR OTHER
PERROS
PROVISIONAL SPECIFICATION left by the said Joseph Whitley at the Office
of the Commissioners of Patents on the 15th February 1883.
JOSEPH WHITLEY of Railway Works, Leeds in the County of York Engineer
and Founder IMPROVEMENTS IN THE CONSTRUCTION OF GOVERNORS FOR THE
PURPOSE OF CONTROLLING AND INDICATING THE SPEED AND POWER OF STEAM
ENGINES AND FOR OTHER PURPOSES
The improvements consist in the construction of a vessel or otherwise and which
I charge or load with mercury, shot or other suitable material and which I attach
to a pulley scroll lever or other actuater for the purpose of manipulating the valve
or valves or other regulator of the Engine or other motor or machine the vessel
having a valve or tap or other regulator for the purpose of facilitating the removal
of any required quantity of the mercury shot or other material so as to reduce the
speed and power of the Engine or other motor or machine to any known speed or
power that may be required the same being indicated by a graduated scale or
otherwise and which mercury or shot or other suitable material may be removed
from or added to the vessel or other arrangement at will whilst the engine or
other motor or machine is in motion thereby increasing or reducing the speed and
power as required without stopping the Engine or other motor or machine

by the said Joseph Whitley in the Great Seal Patent Office on the 3rd August

JOSEPH WHITLEY of Railway Works Leeds in the County of York Engineer
and Founder IMPROVEMENTS IN THE CONSTRUCTION OF GOVERNORS FOR THE
PURPOSE OF CONTROLLING AND INDICATING THE SPEED AND POWER OF STEAM
-ENGINES AND FOR OTHER PURPOSES
The improvements consist in the construction of a vessel or otherwise and which
I charge or load with mercury shot or other suitable material and which I attach
to a pulley scroll lever or other actuater for the purpose of manipulating the valve.
or valves or other regulator of the engine or other motor or, machine the vessel
having a valve or tap or other regulator for the purpose of facilitating the removal
of any required quantity of the mercury shot or other material so as to reduce the
speed and power of the engine or other motor or machine to any known speed or
power that may be required without stopping the engine I also so construct the
vessel or otherwise formed apparatus that mercury shot or other suitable material
may be added to the quantity already placed in such vessel or otherwise formed
apparatus so as to increase the speed and power of the engine or other motor or
_machine if so required. By the adding to or letting out a given quantity of
mercury shot or other material as per an indicated scale previously adjusted to the
known requirements of the case and which may be read off from the indicator
subsequently the same being indicated by a graduated scale or otherwise the speed
and power of the engine motor or other machine is thereby increased or reduced at
will whilst the engine motor or other machine is in motion to any previously
ascertained speed and power indicated upon a given scale or otherwise registered
without stopping the engine or other motor or machine.
Having now described the nature of my said Invention I wish it to be understood
that I in no way limit myself to these several modes of construction and application
or to the precise form or arrangement of the apparati as hereinbefore described as
these may be variously modified without departing from the nature of my
Invention but what I claim as new and novel in my Invention is
First. The Introduction of mercury or other suitable material as a weighting
medium for the increasing or diminishing of the speed and power of Steam Engines
and for other purposes substantially as hereinbefore described.
Second. The Introduction of a scale indicating the ascertained speeds and powers
of the engine motor or other machine in conjunction with the rise and fall of the
governing material contained in the hereinbefore mentioned vessel or otherwise
formed apparatus substantially as bereinbefore described
In witness whereof I the said Joseph Whitley have hereunto set my hand and
seal this second day of August in the year of Our Lord one thousand eight hundred
and eighty three
