A New or Improved Automatic Steam and Water Reducing Valve.
We, JOE BOOTH WHITELEY, WILLIAM WHITELEY, and EDWARD WHITELEY,
of Prospect Iron Works, Lockwood, near Huddersfield, Yorkshire, Machine Makers,
do hereby declare the nature of this invention to be as follows:-
:-
This invention has reference to a new construction of valve for reducing the
pressure of steam and water, the arrangement being of such a character that the
steam or water is the medium by which the pressure is reduced.
In carrying out our invention we employ a suitably sized steam chest or box
having openings therein for the inlet and outlet of steam or water. In connection
with the inlet pipes we place a high pressure valve of an ordinary or other suitable
construction, and in connection with the outlet of the said steam chest we place
a piston working within a cylinder. Upon the top of the steam chest a lever
is suitably hinged, the longer arm of which lever is connected by a pin to the top of
the piston rod, whilst an adjusting weight is placed on the end of said lever to
regulate the pressure of the steam, therefore when steam or water enters the valve
chest at a given pressure, and passes through the high pressure valve, it is then free
to act upon the piston, and if the steam exceeds a given pressure the piston is raised
thereby, in doing which the piston rod actuates the weighted lever previously referred
to, causing the opposite end of such lever to press upon the spindle of the high
pressure valve in such a manner as to reduce the pressure of the steam or water
entering therein.
By the employment of the piston and weighted lever as herein described it is
evident that whenever the steam or water in the chest exceeds the pressure it
is proposed to reduce the steam to, that the piston will rise and cause the weighted
lever to act upon the high pressure valve, which at once diminishes the pressure
of steam or water entering therein.
It must be understood that so long as the pressure of steam or water is not excessive,
that the admission valve works independently of the piston, but if the pressure

page_text: becomes excessive, the piston causes the weighted lever to act upon the admission
valve as above described.
By the construction and arrangement of the valves as herein described, the pressure
of the steam or water directs, controls, and reduces its own pressure.

A New or Improved Automatic Steam and Water Reducing Valve.
We, JOE BOOTH WHITELEY, WILLIAM WHITELEY, and EDWARD WHITELEY, of
Prospect Ironworks, Lockwood, near Huddersfield, Yorkshire, Machine Makers,
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 has reference to a new construction of valve for reducing the
pressure of steam and water, the arrangement being of such a character that the
steam or water is the medium by which the pressure is reduced.
In carrying out my invention. I employ a suitably sized steam chest or box having
openings therein for the inlet and outlet of steam. or water. In connection with the
inlet pipes we place a high pressure valve of an ordinary or other suitable construction,
and in connection with. the outlet of the said steam chest, we place a piston working
within a. cylinder. Upon the top of the steam chest a lever is suitably hinged,
the longer arm of which lever is connected by a pin to the top of the piston rod,
whilst an adjusting weight is placed on the end of said lever to regulate the pressure
of the steam.
In order that our invention may be better understood, reference is made to the
accompanying sheet of. Drawings, which is sectional representation of automatic valve
constructed according to our invention, wherein A is the steam chest or box, B being
the inlet thereto, and C the outlet therefrom. Within the entrance part of the steam
chest is a high pressure valve D connected to a vertical spindle E carried on the end
of a short arm F having its fulcrum at G on the top of a short pillar rising from the
steam chest. Near the outlet part of the steam chest is a piston H working in
a cylinder I. To the piston is attached a piston rod J. whose..upper end is connected

page_text: by a pin to a horizontal lever K hinged at L to a suitable bracket rising from
the steam chest; an adjustable weight M is placed on one end of the horizontal lever
for the purpose of setting and adjusting the said piston to a given pressure.
The action of the apparatus is as follows:-The piston H is set to be raised
by a given pressure of steam; therefore when steam or water is about to enter the
steam chest it passes through the high pressure valve D into the steam chest A, where
it is free to act upon the bottom of the piston H, and if the steam or water exceeds
the given pressure the piston is raised thereby, in doing which the piston rod lifts the
weighted end of the lever K causing the free or opposite end N thereof to press upon
the upper end of the spindle E of the valve D in such a manner as to reduce the,
aperture or opening in the valve, consequently reducing the quantity of steam
or water entering therein.
By the employment of the piston and weighted lever as herein described it is
evident that whenever the steam or water in the chest exceeds the pressure it
is proposed to reduce the steam to, that the piston will rise and cause the weighted
lever to act upon the high pressure valve, which at once diminishes the pressure
of steam or water entering therein.
It must be understood that so long as the pressure of steam or water is not
excessive, the admission valve works independently of the piston, but if the pressure
becomes excessive, the piston causes the weighted lever to act upon the admission
valve as above described.
By the construction and arrangement of the valves as herein shewn and described,
the pressure of the steam or water both controls and reduces its own pressure.
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 :-
Firstly. In a steam reducing valve, the combination therewith of a valve spindle E,
piston rod J, and free ended lever K, for automatically reducing the pressure of
steam or water in manner substantially as set forth.
