An Improved Fluid Pressure Reducing Valve.
We, EDWARD MAKIN Junior, of 33 New Brown Street, Manchester, in the County of
Lancaster,
ster, Manufacturer, and DAVID SPEIRS, of 514 Derby Terrace, Breightmet, near
Bolton, in the said County, Engineer, do hereby declare the nature of this Invention
to be as follows:-
read
Our invention relates to an improved steam or other fluid pressure reducing valve,
and consists in a novel arrangement and combination of parts.
In the passage leading from the steam generator to the steam vessel such as a kiér
we fit a, valve arranged to open under any desired steam pressure. The spindle of
this valve passes out of its casing through a gland and is connected to one end of a
lever the other end of which is connected to the spindle of a piston of larger area than
the valve and fitted in the steam passage leading to the kier or other vessel on the
delivery, side of the first valve. The steam when it has reached the desired pressure
in the generator lifts the valve and flows through it and the steam passage to the kier
or other vessel but when the steam pressure in the latter, exceeds the prescribed
limit the steam continuing to flow through the open valve and acting on the piston
of larger area than the valve forces the piston outward and through its spindle the
lever and the valve spindle closes the valve and shuts off the supply of steam until
the pressure in the kier or other vessel has been reduced below the normal limit when
the steam from the generator will again lift the valve and admit more steam to the
kier or other vessel.

An Improved Fluid Pressure Reducing Valve.
We, EDWARD MAKIN Junior, of 33 New Brown Street, Manchester, in the County of
Lancaster, Manufacturer, and DAVID SPEIRS, of 514 Derby Terrace, Breightmet, near
Bolton, in the said County, 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 :—
Our invention relates to an improved steam or other fluid pressure reducing valve,
and consists in a novel arrangement and combination of parts, as illustrated by the
accompanying Drawing and as hereinafter pointed out in the Claims.
In this Drawing, which is a sectional elevation of our improved valve, a designates
the pipe or passage leading from the steam generator to the steam vessel such as a
CD

page_text: kier, 6 the valve casing, and c the pipe or passage leading from the valve casing to
the kier. In the casing b we fit a valve d arranged to open under any desired steam
pressure from the generator. The spindle e of this valve passes out of the casing b
through a gland fand is connected to one end of a lever g which is fulcrümed on a
bracket secured to the casing b.; The lever g has a weight i secured to it and at
the other end is connected to the spindle ; of a piston k of larger area than the
valve d, and fitted in the steam passage leading to the kier or other vessel on the
delivery side of the first valve d, the piston being exposed to the atmosphere on
the outside and acted on by steam pressure on the inside.
The steam when it has reached the desired pressure in the generator lifts the
valve d and flows through it from the pipe a and through the steam passage c to the
kier or other vessel; but when the steam pressure in the latter exceeds the prescribed
limit the steam continuing to flow through the open valve d and acting on the
piston k of larger area than the valve d forces the said piston outward and through its
spindle the lever g and spindle e closes the valve d and shuts off the supply of steam
until the pressure in the kier or other vessel has been reduced below the normal
limit, when the steam from the generator will again lift the valve d and admit, more
steam to the kier or other vessel. The lift of the valve d is controlled by a screw, and
hand wheel m so that the valve can be screwed down when required.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what, we
claim is:-
1. In combination, the steam inlet passage a, the casing 6, steam outlet passage c,
valve d, lever g, and piston k, all arranged and operating substantially as herein set
forth.
2. The general combination and arrangement of parts constituting our improved
fluid pressure reducing valve substantially as herein described and as illustrated by
the accompanying Drawing.
