A New Valve adapted for Engine Governors, and for Steam,
Hydraulic, and other purposes.
CHARLES COUTTS COOPER 94 Glengall Road Peckham S.E. (Engineer) do hereby
declare the nature of this invention to be as follows:--
My new valve is made of iron gun metal or other metal to suit the class of
fluids, arranged as follows the valve box divided in various number of outlets as may
be required the centre of same to have separate hole for the spindle of valve to pass
through and the wheel for working the valve to be at the back of valve box, the valve
revolving on face of valve box, with passages through valve corresponding to passages
on valve box a cover over valve with inlet at side or any other part as may suit best
thus the pressure can be worked either on or under the valve by this arrangement no
packing is required to any part of the valve or spindle.

A New Valve adapted for Engine Governors, and for Steam,
Hydraulic, and other purposes.
I, CHARLES COUTTS COOPER, of 94, Glengall Road, Peckham, in the County, of
Surrey, also of 15 Chesterfield Grove, East Dulwich, in the County of Surrey aforesaid,
Engineer, 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 :-
This invention relates to a valve adapted for engine governors, and for steam,
hydraulic, and other purposes which is simple in construction, requires no washers or
other packing, and which is so made and fitted that access to the working parts can
be easily obtained when desired.
In the accompanying drawings Fig. 1 is a vertical section and Fig. 2 a plan with
the cover removed of a valve constructed according to this invention,
A and B are the valve inlet and outlet ports respectively, C is the valve cover which
is screwed at c c into the valve casing D which latter is itself screwed at d d to the
valve box E. The valve box E is provided with a central cylindrical boring e and
with a valve seat E¹. F is a disc va ve having a number of ports therein which
correspond in number and position with ports el in the valve seat E which are in
open communication with an annular chamber G leading to the ontlet port. B. The
under side of the valve F is formed or provided with a central cylindrical stem Fi
Prise d

page_text: which is made to accurately fit the boring e in the valve box. The lower end of this
stem F projects through the bottom of the valve box and is furnished with a radial
arm H. J is a spring which takes a bearing on the underside of the valve box E and
on the upper part of the root H' of the arm H tending to force the latter down and
thus to keep the valve F on its seating. K is a collar, or its equivalent, fixed on or
formed in one with the underside of the valve box to keep the spring J in proper
position. The valve is opened or closed by a partial retation of the arm H.
When the valve is opened the ports f and ef are in register and the fluid passes in
the direction indicated by the arrows in Fig. 1. It will be seen that the valve
operates on the "hit and miss "principle and that the pressure of the fluid is on the
top of the valve, tending to keep it closed tightly on its seating. The working faces
of the valve and seating, and of the valve stem and the boring in which it is fitted,
are faced perfectly true.
To gain access to the interior of this form of valve it is only necessary to unscrew
the cover C, and if desired to unscrew the casing D. Then by disconnecting the
arm H the valve F may be raised off its seating.
Several modifications may be made without departing from the nature of the
invention. For example more than one outlet may be provided if required; B may
be the inlet port and A the outlet in which case the pressure being on the underside
of the valve, it would be necessary to provide a stronger spring J to keep the valve
close on its seating; also the inlet may be situated below the valve and open into a
chamber under the valve seating, the way being through the seating and valve ports
across the top of the valve and down through the valve and seating ports on the
opposite side into a second chamber leading to the outlet port or ports as the case
may be. But these are details of construction not affecting the general character of
the invention.
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 :-
A valve comprising inlet and outlet ports, a valve casing carrying a perforated
seating and having a central cylindrical aperture therein, a perforated disc valve with
a central cylindrical stem fitted in the central aperture aforesaid and projecting
through the bottom of the valve casing and furnished with an arm or other means by
which it may be rotated, the valve being held on its seating by a spring bearing on
the outside of the valve casing and on a fixed part of the valve stem substantially
as described and illustrated by way of example in the accompanying drawings.
Dated this 10th day of May 1896.
