GEORGE BEN GOODFELLOW and ROBERT MATTHEWS both of Hyde in the
County of Chester "IMPROVEMENTS IN THE CONSTRUCTION OF APPARATUS FOR
REGULATING OR GOVERNING THE SPEED OF STEAM ENGINES OR OTHER MOTORS"
This Invention has for its object the making of "governors" more sensitive and
capable of governing with variable loads and variable steam or other pressures,
whereas in most existing "governors" the variation in load when great, has to be
attended to by adjusting the governor or governor rods by hand.
The Invention consists in applying two cylinders to any governor of the pen-
dulum or other form already known, tho said cylinders being fitted with pistons
both coupled on to the same rod and to which is attached the throttle valve or cut
off rod.
One of the cylinders has cast or fixed on to it a valve chest in which works
a valve of the piston, slide, or other form, so constructed as to be capable of
giving steam or other fluid pressure to one side of the piston, or to the other,
and when the said pressure is given on one side the other is exhausted; the other
cylinder which is filled with liquid in which works one of the aforesaid pistons,
has a valve chest fixed or cast on to it in which works a valve of the piston, slide,
or other form of known construction, so arranged that when motion is given by
the "governor" from its working position, either way a communication is made
from one side of the piston to the other. The two valves are worked by the rise and
fall or movement of the "governor." The travel of the valve is adjustable and the
openings or valves are so constructed that according to the travel of valve so will
be the speed of action of the "governor" and when the "governor" is in its correct
position for speed the piston in the liquid cylinder will be locked at any part of
its stroke by the valve having closed the communication from one side to the other,
thus meeting the defect in most other "governors.”

GEORGE BEN GOODFELLOW and ROBERT MATTHEWS both of Hyde in the
County of Chester * IMPROVEMENTS IN THE CONSTRUCTION OF APPARATUS
FOR REGULATING OR GOVERNING THE SPEED OF STEAM ENGINES OR OTHER
MOTORS
"
This Invention has for its object the making of "governors" more sensitive and
capable of govering with variable loads, and variable steam or other pressures,
whereas in most existing "governors" the variation in load, when great, has to be
attended to by adjusting the governor or governor rods by hand.
Such being the nature and object of our said Invention we will now proceed to
describe the manner in which the same is to be or may be performed or carried into
practical effect and in order that the same may be clearly understood we have
annexed hereunto a Drawing representing our Invention in longitudinal section and
have marked the same with letters of reference corresponding with those in the
following explanation thereof.
This Invention consists in applying two cylinders a, a and b, b to any governor
of the pendulum or other form already known, the said cylinders being fitted with
pistons c, c and d, d both coupled on to the same rod ff by preference but each
piston may be coupled onto its own separate rod if thought desirable in which case
the relative strokes of the two pistons may be varied.
The piston rod f, f is attached to the throttle valve or cut off rod.
One of the cylinders a, a has cast or fixed on to it a valve chest g, g in which
works a valve h, h of the piston slide or other form so constructed as to be capable
of giving steam or other fluid pressure to one side of the piston c, c or to the other,
and when the said pressure is given on one side the other is exhausted through
the passage e, e and vice versa.
The other cylinder b, b which is filled with liquid in which works the other of
the aforesaid pistons d, & has a valve chest i, i fixed or cast on to it in which works a
valve k, k of the piston slide or other form of known construction, we prefer how-
ever as most convenient to make the valves i, i and k, k in the piston form of a
single rod as shown, the end 7 whereof is connected to the "governor."
The valves are so arranged that when motion is given to the "
governor" from
its working position, either way steam is admitted into the cylinder a, a and a
communication is made from one side of the piston d, d to the other.
The two valves ii and k, k are worked by the rise and fall or movement of
the "governor."
The travel of the valve may be adjustable and the openings or valves are so
constructed that according to the travel of valve due to the amount of fluctuation
of the governor so will be the speed of its action and when the governor is in its
correct position for speed, the piston in the liquid cylinder will be locked at any
part of its stroke by the valve having closed the communication from one side
to the other as shown in the Drawing thus meeting the defects in most other
governors."

Having now described the nature and object of our said Invention together
with the manner in which the same is to be or may be performed or carried into
practical effect we would remark in conclusion that we do not wish to limit
ourselves to the particular form and arrangement of our Invention as illustrated
by the annexed Drawing, as the same may be varied considerably without
