and the Means of Actuating same.
CHARLES STOUT Engineer 12 Westmorland Street in the City of Liverpool,
County of Lancashire do hereby declare the nature of this invention to be
as follows 1
Improvements in Hydraulic Stooring and starting engine valves and the means of
actuating same. The object of this invention is to more perfectly controll the flow
of liquid in the hydraulic cylinders of steering and starting engines and may be
described as follows-
Where a slide valve and cut off valve are used for the purpose of regulating the
flow of liquid as described in my Patent No. 7713-1885, the lower or cut off valve
instead of being opperated as described in that specification, I use a coarse pitched
screw as described but instead of having a different pitched screw at one end working
into nut in valve I secure spindle to valve and allow end to revolve freely, so arranged
that with the movement of truck or piston, the valve is moved a given distance in one
or other direction and any further movement of said trunk &c. causes the screw to
revolve without moving said valve.
The screw spindle is arranged without a collar in stuffing box, this spindle may be
connected to the steering wheel so that when the wheel revolves in one or other direction
the spindle likewise revolves.
The nut attached to trunk &c. being rigid the valve is moved, the port is opened,
and the trunk moves so long as the steering wheel and screw spindle are allowed to
revolve, but when they stop revolving the screw spindle is moved with trunk at the
same rate and in the same direction and with it the cut off valve which stops the flow
of liquid.
One valve only may with this arrangment regulate the flow of liquid.
To describe my valve to work in connection with the above that is where directly
attached to screw spindle end and capable of moving any required distance I prefer a
cylindrical form, hollow with each end stopped and spaces cut opposite each other to
allow the liquid to enter and leave.

page_text: I have two ports in valve cylinder or where flat valve is used on seat: one to top
and one to bottom end of main cylinders.
The valve cylinder is closed at each end and between each end of valve and the end
of valve cylinder a port is left to allow liquid to pass in or out as desired.
The spaces cut out in valve will be somewhat shorter than the distance between the
ports and the extreme length of valve will be somewhat longer than the distance
outside the ports so that the two ends form a complete covering for ports when the
valve is in centre.
•
Therefore any movement of valve opens each port, one to eduction and the opposite
one to pressure, by this means any length of travel may be obtained by cutting more
or less space in valve and having ports more or less distance apart.
Where a flat valve is used the eduction ports will be in face at each end corresponding
to those in valve.
If arranged with lever moved by screw spindle at one end and actuating valve
spindle in an opposite direction at the other the ordinary slide valve will do but this is
objectionable because in the event of sea moving rudder the necessary length of travel
cannot conveniently be obtained.
Or a number say 4 lifting valves, one valve opening eduction and one opening
pressure at the same time working on seats in any convenient part and arranged so
that a load is always upon them capable when not otherwise influenced of closing said
valves, these valves may be actuated by lever or its equivalent, or by a friction cam or
clamp so adjusted that when moved one way it opens two valves and allows liquid to
flow into one end and out of the other, when moved in an opposite direction it opens
the other two valves and allows a similar action only at the opposite end of cylinder
and when left at rest the load on valve closes them so that whilst the steering wheel is
being moved the cam or clamp opens the valves and when the steering wheel is at rest
the load closes the valve.
Delivered under my hand this day 18th August 1886.

page_text: and the means of Actuating same.
I CHARLES STOUT Engineer, of 12 Westmoreland Street, City of Liverpool County
of Lancashire 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 :—
The object of this invention is to more fully control the flow of liquid in the
Hydraulic cylinders of a Steering or Starting engine.
Where the slide 1 and cut off 2 valves are used for the purpose of regulating the
flow of oil as described in my Patent 7713-85 the lower or cut off 2 valve instead of
being opperated as described in my specification 1 use a coarse pitched screw 3 but
instead of having a different pitched scrow at one end 4 working into a nut in valve,
I secure spindle to valve and allow spindle to revolve freely so arranged that with the
movement of trunk 5 or piston rod the valve is moved a given distance in one direction
or the other, and any further movement of trunks 5 or piston rod causes the screw 3 to
revolve without moving the valvo. The screw 4 spindle is arranged without a collar
in the stuffing box: this spindle may be connected to the steering wheel so that when
the wheel revolves in one or other direction the spindle likewise revolves; the nut 6
attached to the trunk 5 being rigid the valve is moved, the port opened and the trunk 5
moves and continues to move so long as the steering wheel and the screw spindle 4
continues to revolve; but when the screw spindle 4 is stopped, then the screw
spindle 4 is moved by the trunk 5 in the same direction & speed, and with it the
cut off 2 valve until the ports 7 are closed and the trunk stops One valve only may
with this arrangement regulate the flow of liquid, but that valve is preferably a piston
valve (although a cylindrical slide will do) by the piston valve any reasonable length of
stroke may be obtained, and in the event of the rudder being struck by a sea the port
in communication with the end of cylinder that receives the shock is opened and the
piston forced into the position it occupied before such shock.
Or instead of the principle as above described a number say 4 lifting valves A one
open to eduction AI and one to pressure at the same time working on seats in
any convenient part and arranged so that a load is always upon them capable when
not otherwise influenced of closing same; these valves may be actuated by lever or
its equivalent, or by a friction cam B or clamp so adjusted that when moved one
way it moves two valves A & A 1, one to allow liquid to flow into one end and
the other to allow liquid to flow out of the other end of cylinder but when
the moving power stops then the valves closes; by this means, the fact of turning a

page_text: steering wheel one way keeps the valves opened, allowing the piston to move in one
direction and when the steering wheel is moved the other, with the opposite effect
upon the said piston, by the other two valves being actuated as described.
Having fully described my invention and the manner of its application I now
claim the following
First. The combination of screw, spindle, and valve as described, actuated by nut
connected to piston rod or trunk as described and for the purpose described.
Second. The combination of a series of valves and seats, levers cams & clamps,
actuated by a steering wheel or otherwise as described and for the purpose described.
Given under my hand this day May 16th 1887.
