PROVISIONAL SPECIFICATION.
Improvements in Automatic Water Gauges for Steam Boilers and
the like.
EDWARD STAMFORD HOUGH Engineer 2 Adelaide Road Brockley Kent do
hereby declare the nature of this invention to be as follows:-
My invention relates to an improvement in automatic water gauges such as
described in my Specifications Nos. 6126 and 12857**
Its object being to simplify the working of the valves by the hand levers and to
facilitate the substitution of new valves or valve seats when required.
For this purpose I provide lugs, or open ended square boxes on the top of the
automatic valves and the inner end of the screwed spindles have projections, or
square ends, loosely fitting into these lugs, or the square boxes on the valves so as
to cause the valves to rotate when the spindle is moved by means of the hand lever
-the spindle having on it a coarse pitched thread working through a female thread
and stuffing box, and having on its outer end a hand lever-the action being on
turning this lever the valve is rotated and at the same time forced down on to its
seat, or lifted off as may be desired. I leave sufficient play in the box or lugs, so
that when this lever is left in its intermediate position it allows the valve to close
automatically on the breakage of the glass or in blowing through the drain valve.
These valves have their boxes placed diagonally and they represent an ordinary
non return valve (with connections to spindles as described) upside down, so that
when the pressure is equal on both sides they drop open by their own weight. I also
put an indicating pointer or plate shewing the position of the valve inside viz. " valve
open," "automatic," valve shut." I provide loose valve seats to these automatic
valves, the seats being screwed or otherwise fixed into the body of mounting and
the seats have square holes in them, this provision 1 make for the purpose of readily
renewing a worn out seat. The blow through or drain valve has a loose seat with
square hole through same and a flat face so that I can use soft material on the face
of the valve. I make the valve cup shape to prevent the soft material spreading.
This arrangement of drain valve enables me to renew both the soft material and the
valve sent itself.

COMPLETE SPECIFICATION.
Improvements in Automatic Water Gauges for Steam Boilers and
the like.
I, EDWARD STAMFORD Hough, Engineer of 2 Adelaide Road, Brockley, Kent,
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 thereof :-
My invention relates to an improvement in automatic gauges such as are described
in my previous Specifications No. 612 of 1886 and No. 12857 of 1888.
The object of my present invention is to simplify the working of the valves by
the hand levers and to facilitate the removal of the valves and the substitution of
new valves when required, as I shall describe referring to the accompanying
drawings.

page_text: Fig. 1 is an elevation of a glass gauge shewing the valve boxes at the ends,
Fig. 2 is a longitudinal section of one of the valve boxes and
Fig. 3 is a transverse section of the head of the valve.
I form the end of the valve rod R as a T head which enters a transverse slot
formed in the head H of the valve, this slot having inwardly projecting lips h, under
which the shoulders of r engage, so that, on turning the screwed rod R in the one
direction, the valve is raised from its seat, and on turning R in the opposite direction
the valve is pressed against its seat, being in both cases turned round. Usually the
valve, after being seated, is raised a little by turning the rod R in the one direction,
after which the rod is turned a little back, and there is sufficient freedom left in the
valve slot for the head r, to allow the valve to close automatically, in case of
fracture of the gauge glass.
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 and valve rod for an automatic. water gauge having the valve head
slotted and a T end of the valve rod engaged in the slot, substantially as described.
Dated this 3rd day of May 1894.
