PROVISIONAL SPECIFICATION.
Improvements in or relating to Hydraulic and other Valves.
We, FRANCIS LAWRENCE LANE, of 66, Cardigan Road, Headingley, Leeds, in
the County of York, Engineer and Manager, and WILLIAM RAINFORTIL, of
Edinboro' Grove, Upper-Armley, Leeds, aforesaid, Engineer, do hereby declare
the nature of this invention to be as follows:-
In accordance with this invention we operate the spindle or spindles con-
trolling the ways or ports of hydraulic and other valves by means of any suitable
mechanical inclined-plane actuated by hand or power in any convenient manner.
In one instance we construct a hydraulic valve with four spindles two of which
control the outlet or exhaust ports whilst two control the inlet or live ports. One
end of each of the said spindles is placed within an adjustable sleeve arranged to
hear and work upon a circular disc having part of its area of a varying thickness
so as to be in cross-section of a wedge-shaped form. The compression upon the said
disc may be adjusted by means of springs suitably attached at the other ends of
the said spindles. The said disc is secured to a hand-lever of any convenient
design in such wise that by operating the latter the said dise may be moved in
either direction away from a given centre and so actuate the spindles controlling
the respective ports as may be desired.
Various apparatus may be devised without departing from the nature of this
our said invention..

We, FRANCIS LAWRENCE LANE, of 66, Cardigan Road, Headingley, Leeds, in
the County of York, Engineer and Manager, and WILLIAM RAINFORTH, of
No. 6, Edinboro' Grove, Upper Armley, Leeds, aforesaid, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
This invention relates to hydraulic and other valves and has for its object the
provision of means for readily operating a group of two or more valves through
the medium of inclined surfaces mechanically actuated by hand or other power
in any convenient manner.

page_text: In order that our invention may be the better understood we will now proceed
to describe the same in relation to the accompanying drawings hereunto annexed
reference being had to the letters and figures marked thereon. Like letters refer
to like parts in the various figures.
Figure 1 is a part sectional view of a form of a hydraulic valve made according
to our invention in which there are two supply and two exhaust valves which
have to be alternatively operated in pairs by a device having a circular_motion
the section of the valve spindle and operative gear being taken on the line re
Figure 2.
.
Figure 2 is a plan of the operating device as seen from below.
Figure 3 show's a plan of the disc carrying the inclined surfaces for operating.
the valves; and side views of these surfaces.
Figure 4 shows detail views of the valve spindle and adjustable sleeve with
inclined face.
Figure 5 is a modified form of valve lifting device in which a reciprocating
rectilineal motion is substituted for the circular motion.
Figure 6 is a plan of the reciprocating plate carrying the inclined surfaces.
To carry our invention into effect in a valve having four spindles a a a' a¹,
two of which a à control the inlet or live ports while the other two a¹ a control
the outlet or exhaust ports. These spindles are carried through the bottom of
the valve casing and are screw threaded on their exterior portion. Between two
lock nuts a sleeve c is secured on each spindle, the said sleeve being provided
with inclined faces d. A central support or stud es supported on and projects
downward from the bottom of the valve casing. This stud e carries rigidly two
guide plates ff and also forms a pivot for the operating disc g which is
journaled thereon between the guide plates f f
The disc g is provided with inclined surfaces h which coact with the inclined
surfaces of the sleeves when the disc is moved about its axis relative to the
sleeves by any convenient handle m, and the surfaces are arranged to lift and lower
the spindles in pairs, ie, spindles a and a forming a pair at each alternative
motion, in other words the supply on one side and the exhaust on the other is
opened while the converse obtains in the other pair at the same operation.
The sleeves are provided with flats which engage in slots i in the guide
plates ff so as to effectively guide the spindles and resist any transverse strain
liable to be set up during the operation of the spindles by the disc in its
circular movement. Springs are provided in the cap which press the spindles
downward to keep the valves normally on their seats. The lift of the spindles
is regulated by adjusting the position of the sleeve e by means of the lock
nuts, Slots are provided in the disc g through which the sleeves c and
spindles pass, the length of the slots being sufficient to permit the proper rotation
of the disc to lift the spindles to their full height.
In Figures 5 and 6 we show a modified arrangement by substituting a rectilineal
moving plate for the rotating disc. In this case the plate 7. is provided with
inclined surfaces h two being arranged on one side of the plate and one with
double inclines on the other. The four slots & are also provided but in this case
they are parallel to one another in pairs.
The movement of the plate is effected by the bell crank lever n and the general
operation is the same as hereinbefore described.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is:-
=
1st. In a valve haring two or more spindles to which an alternative or inter-
mittent action has to be applied, the arrangement of surfaces inclined to the
axes of the spindles carried by a support and adapted to move transversely relative
to the said spindles to lift and lower the same, substantially as described.
2nd. In a valve having two or more spindles to which an alternative or inter-

page_text: mittent action has to be applied the combination of surfaces inclined to the axes
of the spindles carried by a support and adapted to move transversely relatively
to the said spindles, with sleeves adjustable upon the said spindles, substantially
as described.
3rd. In a valve having two or more spindles to which an alternative or inter-
mittent action has to be applied, the combination of surfaces inclined to the axes
of the spindles carried by a support and adapted to move transversely relatively
to the said spindles, sleeves adjustable upon the said spindles, with guide plates
or the like rigidly carried by the valve casing the said guide plates being adapted
to guide the spindles axially. substantially as described.
4th. A valve arrangement and operating gear constructed and arranged, sub-
stantially as described and illustrated in and by the accompanying drawings.
