Improvements in Valves and Fittings for Steam, Water, or
other Fluids.
I, INGLIS Ross of 19 South Saint James Street in the City and County of
Edinburgh Engineer, do hereby declare the nature of this invention, to be as
follows:-
My invention has reference to a new or improved construction, or arrangement and
combination of the parts, of valves and valve chests and their fittings, which will be
very applicable for high and low pressure steam, water and other fluids, and for giving
full, free and unobstructed flow and delivery of the fluids through them, and suitable
for easy connection or coupling to their supply and service pipes, and their branches ;
while being more easily actuated or opened and closed and made and retained perfectly
fluid-tight and more easy of access for inspection or cleaning, than such valves have
been as heretofore constructed.
The nature and novelty of my invention consist all as follows:-The valve chest
proper is formed at one end, and a lateral outlet chamber at the other, both opening
to a face on one side closed by a screwed-on or other flat door or cover, with duct in
it leading from the one chamber to the other.
The inlet and outlet branches lead into these in a straight line, (but they might be
formed laterally at right or other angles as desired), to suit the supply and service
pipes, and these branches might be as screwed or other faucet or spigot joints or with
Banged joints, to suit the pipes to which they are to be coupled. The valve chamber
would be large enough to allow of a flat swivelling valve being inserted through the
said opening in the top or one side; and fulcrummed on a transverse spindle passed
in through a stuffing box in one side of the valve chamber, the spindle being attached
loosely through the eye of the valve with a deep longitudinal feather so as to allow the
valve to adjust itself to the seat and close perfectly tight on its seat, which is screwed
or fitted on the under side of the cover projecting down into the valve chamber at the
other side, this valve seat leading up into the duct in the cover communicating with
the outlet chamber.

page_text: The spindle of the oscillating valve has secured on it, outside its stuffing box at one
side a worm wheel with a screw working in it on a short spindle carried in bearings
projecting out from the valve chest, or from the valve chest and the cover before
mentioned, with a hand wheel secured on the outer end of the screw spindle for
actuating it and the valve spindle through the worm and worm wheel, which would
open or close the valve with great force against the pressure of the fluid whether this
was acting on the face or back of the valve to make it perfectly tight, or hold the
valve in any position desired the valve chest being made large enough to swivel the
valve quite down and leave a free unobstructed opening through the valve seat and
cover to the outlet chamber at the other end of the valve chest. In some cases this
valve might be actuated by a hand wheel on the valve spindle itself (without the worm
wheel and worm spindle) and notches or other equivalent might be formed on the side.
of the hand wheel with a spring catch or other equivalent which would hold the valve
close or open, or in any mean position between these as desired.

Improvements in Valves and Fittings for Steam, Water, or
other Fluids.
I, INGLIS ROSS, of 19 South Saint James Street, in the City and County of
Edinburgh, Engineer, do hereby declare the nature of my said Invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement in writing reference being had to the accompanying
Sheet of Drawings and to the letters and figures marked thereon that is to say:-
My said invention has reference to a new or improved construction, or arrangement
and combination of the parts, of valves and valve chests and their fittings, which will
be very applicable for high and low pressure stean, water and other fluids, and for
giving full, free and unobstructed flow and delivery of the fluids through them, and
suitable for easy connection or coupling to their supply and service pipes, and their
branches; while being more easily actuated or opened and closed and made and
retained perfectly fluid-tight and more easy of access for inspection or cleaning, than
such valves have been as heretofore constructed.
And in order that my said invention, and the manner of performing or carrying the
same into effect or practice may be properly understood, I have hereunto appended an
explanatory Sheet of Drawings in which the same reference letters are used to indicate
corresponding parts in all the Figures where shown.
Figure 1 is a side elevation of my improved arrangement of valve, valve chest and
fittings, and showing the worm and wheel for actuating the valve. Figure 2 is a
corresponding plan with the top cover of the valve chest removed; and Figure 3
shows an inverted plan of the valve chest cover. While Figures 4 and 5 are
longitudinal and transverse vertical sections taken on the lines 1-1 and 2-2,
respectively, each on the other, to more clearly show the construction and arrangement
of my improvements, the latter Figure 5 showing the spindle and valve in elevation.
Referring to these Drawings, the nature and novelty of my invention consist all as
follows:-The valve chest proper A is formed at one end, with a vertical and lateral
outlet chamber B, b at the other, both opening at e, c¹, to a face on one side closed by a
screwed-on or other flat door or cover C, with longitudinal duct C¹ in it leading from
the one chamber A to the other B. The inlet and outlet branches a, b, lead into these
chambers A, B, in a straight line, (but they might be formed laterally at right or
other angles as desired), to suit the supply and service pipes, to be coupled to them ;
and these branches ab might be as screwed or other faucet or spigot joints, or with
flanged joints, to suit the pipes to which they are to be coupled at a and b respectively.
The valve chamber or chest A would be large enough to allow of a flat swivelling
valve A¹ jointed on its eye and arms A³ being inserted through the said opening in
the top face c or it might be at one side. The valve A¹ is mounted loose on a pin a²
by its arms and eye A³ on a transverse spindle A³ passed in through a stuffing box D
formed on one side of the valve chamber A, with screw gland outside. The spindle A³
is attached through the eye A' of the valve A¹ with a deep longitudinal feather, all so

page_text: as to allow the valve A¹ to adjust itself to the seat a¹ and close perfectly tight on this,
which is screwed or otherwise secured or fitted on the under side of the cover C₁
projecting down into the valve chamber A at its face, this valve seat a leading up into
the duct C, which communicates with the outer chamber and branch B b. The
spindle A of the oscillating valve A¹ has secured on it, outside its stuffing box D at
one side, a worm wheel E with a screw E, working in it on a short spindle E
carried in bearings F, F, projecting out from the valve chest A and cover C before
mentioned, with a hand wheel secured on the outer end of the screw spindle E' for
actuating it and the valve spindle through the worm E' and worm wheel E, which
would open or close the valve A¹ with great force against the pressure of the fluid
whether this was acting on the face or back of the valve A' to make it perfectly tight,
the valve chest A being made large enough to swivel the valve A¹ quite down and
leave a free unobstructed opening through the valve seat a¹ and cover C to the outlet
chamber B at-the other end of the valve chest A; all as preferred and indicated by
the arrows; but the fluids might flow in the other direction when desired, the screw
maintaining the valve A¹, so tight against its seat a¹.
In some cases although not preferred or illustrated in the Drawings this valve A¹
might be actuated by a hand wheel on the valve spindle itself (without the worm wheel
and worm spindle) and notches or other equivalent might be formed on the side of the
hand wheel with a spring catch or other equivalent which would hold the valve close or
open, or in any mean position between these as desired.
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 :-
First. The construction or arrangement and combination of valve, and its valve
chest and screw actuating and retaining fittings for steam, water or other fluids,
substantially as herein described, in reference to and shown in the accompanying
Drawings.
Second. In a valve chest A for steam, water or other fluids, the arrangement and
combination of an oscillating valve A¹, A' mounted on a transverse spindle A³ actuated
outside, and leading to an outlet duct or chamber C¹, B, substantially as herein
described in reference to and shown in the accompanying Drawings.
Third. In a valve chest A for steam, water or other fluids, the mounting of the
valve A¹ A on a transverse spindle A' within and passed outside, and actuated and
retained in any desired position by a screw and screw wheel, all substantially as herein
described in reference to and shown in the accompanying Drawings.
