I, CHARLES REGINALD PARKES East Ferry Road, Millwall London, E. Civil
Engineer do hereby declare the nature of my invention for HYDRAULIC AUTOMATIC
GOVERNOR AND EXPANSION GEAR FOR STEAM OR OTHER FLUID PRESSURE ENGINES
to be as follows:-
I
}
This invention consists in using the governor of any steam or other engine to
work the valve or valves of a special hydraulic cylinder or cylinders, so that on
the rise and fall of the governor balls the said valve or valves shall admit and
exhaust water under pressure to the said cylinders, the rams or pistons working in
the cylinders shall move to and fro or up and down or rotate and shall by a
suitable arrangement of gearing, levers, chains or other appliances cause to revolve
the expansion rods of expansion alide valves working on the back of main slide
valves and adjustable by right and left banded screws on the spindles or by lifting
a motion link to alter the stroke of such valves. The water under pressure
required for working the hydraulic cylinders may be obtained from any convenient
source.

or other Fluid Pressure Engines.
I, CHARLES REGINALD PARKES East Ferry Road, Millwall, London, E. Civil
Engineer do hereby declare the nature of my invention for HYDRAULIC AUTOMATIC
GOVERNOR AND EXPANSION GEAR and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
i
This invention consists in using the Governor of any steam or other engine to
work the valve or valves of a special hydraulic cylinder or oylinders, so that on
the rise and fall of the Governor Balls the said valve or valves shall admit and
exhaust water under pressure to the said cylinders, the rams or pistons working in
the cylinders shall move to and fro or up and down or rotate and shall by a
suitable arrangement of gearing levers, chains or other appliances cause to revolve
the expansion rod or rods of expansion slide valve or valves working on the back of
the main slide valves and adjustable by right and left handed screws on the spindles
or by lifting a motion link to alter the stroke of such valves.
The water under pressure required for working the hydraulic cylinders may be
obtained from any convenient source.
DESCRIPTION OF DRAWINGS.
In Figs. 1 and 2. A A shows the Governor of a suitable form operating the
hydraulic valve B which admits and exhausts the water under pressure to and
from the hydraulic cylinder E according to the height the governor balls may rise
as the speed of the Engine varies. The ram or piston as shown at F and G
represents the crosshead to which the straps H H are secured. These straps H H
pass over pulleys keyed to the valve rods C. C., to be rotated for altering the
position of the expansion valves by right and left hand screws. DD are the
weights for revolving the shafts C. C. in the reverse direction when' the water is
exhausted from the hydraulic cylinder E.
I
In Fig. 3 the cylinder and piston K are shown operating the valve rod N so as to
alter the stroke of the slide valve by lifting and lowering the valve rod N in the
link L The link L is fixed at one end and is driven by the eccentric M. The
Governor A. A with the hydraulic valve B as previously described admit to and
release the water from the piston K thereby automatically adjusting the movement
of the valve rod N to the work of the Engine.
In Figs. 4. 5 and 6 a combination of hydraulic cylinders are shown for obtaining
more power by means of multiple pulleys or for giving a series of adjusted
movements to the expansion valves by more than one hydraulic cylinder being
used.
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
1st A suitable hydraulic valve operated by a ball Governor attached to and
Tarins

page_text: 2nd One or more hydraulic cylinders fitted with pistons or rams working therein
and operated by the water under pressure admitted and exhausted by the hydraulic
valve aforesaid.
3rd The arrangements as described for automatically working the expansion
valves on the back of the main slides by suitable connections to the said pistons
or rams as described.
