JOHN ETHERINGTON Consulting & Inspecting Engineer & Sole Manufacturer
& Refiner of "Cylindrine" lubricating Oils 39a King William Street London
Bridge London EC do hereby declare the nature of my invention for IMPROVE-
MENTS IN AND RELATING TO STOP AND SLUICE VALVES FOR THE USE OF STEAM,
WATER, GAS, OR ANY OTHER KIND OF FLUID, to be as follows:
The valve spindles are made pressure or steam tight without the use of packing
entirely, by the adoption of a valve with top seatings in the form of a sleave & nut
screwed to coarse pitch for rapid opening or closing and working in' grooves or
channels attached to the inside shells of the valves, the wheels for opening & closing,
the valve consist of a hollow rim cored out and holes drilled at the ends of arms
into the hollow rim to admit air for keeping starting wheels cool.

JOHN ETHERINGTON M.I.M.E. Consulting and Inspecting Engineer 39ª King
William Street London Bridge London E.C. 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:-
My Invention relates to that class of Sluice or Stop Valve, which is especially
designed for steam, water, gas, or any other liquids opened or closed by a feather
valve, this said feather valve working in grooves or channels on the sides thereof
on a conical valved spindle working in a conical valve seating. The principle
object of my Invention being to do away with all packings, keeping the valve
bearings with uniform pressure against their respective facings without the use of
springs or wedges Secondly-The construction of the cored wheel always being
kept cool by the arrangement of the hollow or cored out rim.
Such being the nature and object of my said Invention, and in what manner the
same is to be or may be performed, I will now proceed to describe in detail the
manner in which the same is to be or may be performed, and in order that the same
may be clearly understood I have annexed hereunto a Sectional Drawing illustrative
thereof and have marked the same with letters of reference.
A. A is the body of valve b. b the spindle guide through which the spindle gets
direct action upon the valve seating h. h. C. C. is conical valve spindle. E. conical
valve to which is screwed left handed male thread d. for feather valve K. K. to
work theron, Lugs on the side's of feather valve F. F to prevent cylindrical
motion. GG grooves or channels for working of the said lugs so that as the
spindle is turned to the right, the feather valve shuts upon seating of the said
body of valve A and as the spindle C. C. is turned to the left so it opens same
thereof.
Having now particularly described and ascertained the nature and object of
my said Invention, and in what manner the same is to be or may be performed,
I declare that what I claim is as follows.
Firstly In Sluice or Stop Valves, opened or closed (the conical valved spindle
working in conical valve seating of saine) and the said feather valve working on
left handed or right handed thread of same.
Secondly. In Sluice or Stop Valves opened or closed, I claim the cored wheel
or cylindrical chamber round the rim of the said wheel, as by having the said
cylindrical chamber there is always a current of cold air passing through same and
by that mean's the said wheel being kept perfectly cool.
