I RICHARD MOUNTFORD DEELEY, Junior, Engineer, of N° 1, Highland Villas,
Mill Hill Road, Derby, do hereby declare the nature of my invention for
IMPROVEMENTS IN VALVES FOR CONTROLLING BY HAND OR OTHERWISE THE
MOVEMENT OF HYDRAULIC AND OTHER ENGINES, to be as follows:-
My invention relates to improvements in hydraulic or other valves for actuating
various kinds of machinery.
The arrangement consists of a piston (trunk or otherwise) in which there is a
valve, partially balanced by preference. This valve is so arranged that a rod or
pipe passing through the cylinder end shall come in contact with it and be capable
of lifting it from its seat, thus establishing a communication between the two ends
of the piston.
When the rod or pipe is not in contact with the valve, the valve is
seated upon the piston, and an exhaust passage is opened between the valve and
the pipe or rod. The exhaust port may pass either through the pipe or through a
hole passing through the centre of the valve.
When the power required is small the piston may be coupled directly to the
object to be moved, but when the power required is very great the ends of the
cylinder containing the small piston and valve may be placed in communication
with larger cylinders, the pistons of which are connected with the smaller piston
containing the valve by suitable gearing.
Valves constructed upon this plan may be used to actuate guns, cranes, lifts, hoists,
shearing machines, punching machines, ships' rudders, reversing gear, &c. &c.
I claim as my invention the placing of a loose valve in a piston, which valve
is actuated by a rod or pipe passing through the cylinder end, and so arranged
that when the rod or pipe is not in contact with the valve the valve is seated upon
the piston, and the opening between the rod or pipe and the valve forms the
exhaust. When on the other hand the rod or pipe is in contact with the valve,
the exhaust is closed and a communication may be opened between the two ends
of the cylinder by raising the valve from its seat.

the Movement of Hydraulic and other Engines.
1 RICHARD MOUNTFORD DEELEY, Junior, Engineer, of N° 1, Highland Villas,
Mill Hill Road, Derby in the County of Derbyshire, do hereby declare the nature
of my invention for IMPROVEMENTS IN VALVES FOR CONTROLLING BY HAND OR
OTHERWISE THE MOVEMENT OF HYDRAULIC AND OTHER ENGINES, and in what
manner the same is to be performed; to be particularly described and ascertained
in and by the following statement:-
My invention relates to improvements in hydraulic and other valves for actuating
and controlling various kinds of machinery.
My improvement consists in so arranging the parts of the valve that any motion
given to the spindle thereof shall cause an exactly proportional movement to be
communicated to the bydraulic or other ram which it is intended to control.
This is effected in the manner shewn in Figures 1, 2, 3, 4, 5, 6, and 7, sheet 1.
of the accompanying drawings.
Figure 1 is a longitudinal and Figure 5 a cross section of one of my hydraulic
valves. It consists of a cylindrical barrel M with stuffing boxes at each end through
which the spindle D and piston rod E. pass. Sliding in this cylinder is a
piston e fitted with two cupleathers, one at each end of the central chamber a.
Water under high pressure is admitted by the pipe A to the chamber a, and through
the holes a¹ to the central valve V. This valve, which is hollow and threaded on
to the rod D, is partially balanced by a spindle passing into the exhaust chamber b.
A spindle D actuates the valve V. The piston rod E, and piston e, which contains
the valve V, is coupled by suitable levers or brackets to the piston or ram whose
motion it is intended to control. The action of the valve is as follows:-The high
pressure water entering the pipe A passes into the chamber a and through the
holes a to the valve V. On the spindle D being forced inwards the valve V is
raised from its seat on the piston e; and water passes into the chamber F and into
the cylinder through the pipe C. The ram and piston rod E are then moved by
the pressure in the cylinder and chamber F until the valve V again seats itself
upon the piston e. If instead of being forced inwards the spindle D is drawn out
some distance the spindle D is parted from the valve V and the water in the
chamber F passes through the hollow valve V, through the perforations b', into
the chamber b, and out-by the exhaust pipe B. As soon as sufficient water has
passed away to allow the piston e to cause the valve V to again become seated
From this it will
upon the spindle D, the piston e and piston rod E come to rest.
be seen that for any amount of stroke given to the spindle D an exactly
proportional movement, with immensely increased force, will be given to the piston
rod E and ram with which it is coupled.

When the power required is,small the piston rod E may be coupled directly to
the object to be moved, but when the power required is very great the chambers F
and a are placed in communication with larger cylinders, the pistons or rams of
which are coupled by suitable levers or brackets with the piston rod E. In
Figure 4, sheet 1, the valve is shewn arranged to work a hydraulic shearing

page_text: machine. The pressure enters the valve by the pipe A and passes by the branch A¹
into the chamber a¹ around the ram E. The pressure in the chamber a¹ presses
upon the piston e¹ and keeps the ram E¹ raised. The ram E¹ is coupled by means
of a bracket to the piston E of the valve. Any motion given to the handle H
actuates the spindle D and valve V either admitting water to or exhausting water
from the chamber F, and since the ram E¹ and piston E are coupled, the opening
and closing of the valve V causes the stroke of the ram E¹ to be exactly similar in
amount to that imparted to the spindle D by the lever H.
Figure 2 shews a longitudinal and Figure 6 a cross section of a modification of
the apparatus. In this design the exhaust port instead of being carried through
the valve V is carried by the passage B through the centre of the spindle D. The
cylinder M is also made in two portions their point of contact forming a stuffing
box around the piston e. The spindle D is actuated by the wheel G and screw d.
Another modification is shewn in Figures 3 and 7. In this design in addition to
the exhaust being carried through the spindle D the inlet A is through the
piston E. Both the spindle D and piston rod E terminate in suitable stuffing boxes.
These stuffing boxes are not shewn in the drawing. The spindle D is actuated by
the lever H. The piston is here dispensod with the valve V being fixed in the
end e of the piston rod or ram E. In other respects the action of the valve is
very similar to those shewn in Figures 1 and 2.
Valves constructed upon this plan may be used with advantage to actuate heavy
guns, cranes, lifts, hoists, shearing machines, punching machines, ships' rudders,
reversing gear, &c, &c.
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:-
Firstly. The construction of valves substantially as herein-before described for
the purpose of controlling the action of various kinds of machinery.
Secondly. The use of such valves without the aid of separate cylinders, pistons,
or rams.
