Improvements in Valves for Water, or other Liquids or Fluids.
We, EZRA SYKES and EDWIN SYKES, of the. Firm of John Sykes and Sons, of
Turnbridge Iron Works, Huddersfield, in the County of York, Machine Makers, do
hereby declare the nature of this invention to be as follows:-
The primary object of our invention is to dispense with the ordinary plug valve
and to use instead thereof a valve of an entirely new and novel construction. In
making a valve according to our invention the inlet orifice is placed in connection
with a pump and the outlet orifice connected to the machine or other purpose to
which it is applied. We employ two valves in one casing a lower one connected
to a central spindle and hand wheel, and an upper one connected to a sleeve or
tube surrounding the central spindle. Both the spindle and the said tube are
attached to separate hand wheels so that the valves can be worked independently
of each other.
When the valve is required to be used for the purpose of passing water or
steam, the upper valve is opened and a clear thoroughfare is obtained. We might
add that this operation can be reversed, the pump being at the opposite end to
When the

valve is employed to draw off waste water, the central spindle is operated and the
lower valve opened whereby waste water can be let off into the drain or other
place to receive it. It will be clearly understood that both valves are actuated
separately.

Improvements in Valves Or Water,
We, EZRA SYKES and EDWIN SYKES, of the Firm of John Sykes and Sons, of Turn-
bridge Iron Works, Huddersfield, in the County of York, Machine Makers, 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 primary object of our invention is to dispense with the ordinary plug valve
and to use instead thereof a valve of an entirely new and novel construction. In
making a valve according to our invention the inlet orifice is placed in connection

page_text: with a pump and the outlet orifice connected to the machine or other purpose to
which it is applied. We employ two valves in one casing a lower one connected to
a central spindle and hand wheel, and an upper one connected to a sleeve or tube
surrounding the central spindle. Both the spindle and the said tube are attached
to separate hand wheels so that the valves can be worked independently of each
other. When the valve is required to be used for the purpose of passing water or
steam, the upper valve is opened and a clear thoroughfare is obtained.
We might
add that this operation can be reversed, the pump being at the opposite end to that
described and the machine at the other end, that is vice versa.
When the valve is employed to draw off waste water, the central spindle is 1
operated and the lower valve opened whereby waste water can be let off into the
drain or other place to receive it.
To more clearly illustrate our invention we will make reference to the
accompanying sheet of drawings, wherein
Fig. 1 is a vertical section of our improved valve.
Fig. 2 is an end or side elevation.
Fig. 3 is sectional plan through line x, x, of Fig. 1, and
Fig. 4 is sectional plan through line y, y of Fig. 1.
a represents the valve casing in which are two valves b and c placed one above
and one below the inlet d, said valves b and c resting upon the valve seats b¹ and c¹2
respectively. Above the valve b is the outlet e which is connected to the machine
by a pump or other motor or object, whilst under the valve c is a second outlet f
which is arranged to be in connection with a drain or other place where dirty or
waste water may be discharged. The lower valve c is connected to a central
vertical spindlog supported at its upper end in bearings in the framework h such 2
framework being bolted to the top of the valve casing a by bolts a¹. On the top
of the vertical spindle is secured a hand wheel g' which acts as a nut and on
the said hand wheel being revolved in either direction, the spindle g is made to
slide up or down vertically, rotation thereof being prevented by means of the
arm g² fixed to the said spindle but engaging at its free end with the slide g
forming part of the framework h, thus by operating the handle g¹ the spindle g is
raised, consequently the valve c is opened and whatever may be passing through
the inlet d escapes at the outlet f providing valve b is closed. The valve bis
connected to a sleeve or tube surrounding the central spindle g but not
connected therewith, such said sleeve being supported at its upper end in 3
a suitable bearing or stuffing box k¹. A screw thread is formed on the
upper end of the sleeve k into which takes a corresponding screw thread
formed in the boss of the hand wheel k¹ so that when the said wheel is
rotated it answers the purpose of a nut causing the tube to move up and down
vertically, the said tube or sleeve being prevented from rotating by an arm k² 4
secured thereto with the free end thereof engaging with the slide on the
framework h in the same manner as the arm g² with regard to the vertical
spindle g. To make a steam tight joint between the parts, a stuffing box
employed to surround the sleeve k. When requiring to pass water, steam or other
fluid through the valve b to the outlet pump, the hand wheel k¹ is rotated so as to 4
raise the tube k, whereby the said valve b is opened allowing water or steam to
pass from the inlet d to the outlet e but if the water or steam is not required
to pass to the pump but has to be discharged through the outlet f, the valve b is
closed and the valve c opened by operating hand wheel g¹ whereby the water or
steam is allowed to run off' to the drain. It will therefore be seen that the two valves 5
can be worked independantly of each other and that in both cases a full and free
thoroughfare can be established in the direction of both outlets.

Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
