We ALLEN RIDGE, Engineer, and JOSEPH BLAKE, Foreman both of Townley Iron
Works Bradford Manchester in the County of Lancaster do hereby declare the nature
of our invention for AN IMPROVED REGULATING VALVE FOR STEAM ENGINES to be
as follows:--
This invention relates to an improved construction of regulating valve to be applied
to steam engines and actuated by the governor, the object of the invention being to
admit the full amount of steam at once or cut off the same by a slight rotary movement
of the valve only.
The body of the valve is cast or made in a cylindrical form about twice the diameter
of the bore of the pipe, or rather larger and at right angles thereto, and is fitted inside
with a fixed cylindrical shell closed at both ends and of lesser diameter so as to leave
an annular passage all round excepting on the inlet side where the bore of the pipe
communicates with an opening in the shell, so as to admit steam into the interior
thereof, the bore at the outlet side communicating with the annular passage before
mentioned.
Inside this fixed shell is mounted the valve which is formed as follows. Upon
the valve spindle (which passes through a stuffing-box) we fix two dises fitting inside
the ends of the cylindrical shell and connected to each other by a series of longitudinal
bars having spaces left between them so as to form a kind of cylindrical grid. The
ends of these bars are let into notches in the circumference of the two dises and a
certain amount of play is allowed thereto so that the outward pressure of the steam
presses them against the inside of the fixed shell so as to make a good joint. The fixed
shell is also provided with longitudinal openings or slits corresponding with the spaces
between the bars and it will be evident that a very slight rotary movement of the
valve (imparted by the governor to a lever fixed on the spindle) will open or close the
several apertures or slits the full length of the shell and thus admit or cut-off the full
amount of steam quickly.
As a modification we propose sometimes to make the apertures or slits in both the
shell and the valve in a diagonal, instead of a longitudinal form, and as a further
modification they may be made in a circumferential direction, but in the latter case
the valve would have to move in a longitudinal direction instead of revolving to open
or close the apertures.

An Improved Regulating Valve for Steam Engines.
We ALLEN RIDGE Engineer and JOSEPH BLAKE, Foreman, both of Townley Iron
Works Bradford Manchester in the County of Lancaster do hereby declare the nature
of our invention for AN IMPROVED REGULATING VALVE and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to an improved construction of regulating valve to be applied
to steam engines and actuated by the governor, the object of the invention being to
admit the full amount of steam, or cut-off the same by a slight rotary movement of
the valve only.
The construction of our improved regulating valve will be readily understood on
reference to the annexed sheet of drawings and the following explanation thereof.
Fig. is a vertical section, and Fig. 2 a horizontal section of a regulating valve
constructed according to our invention, and Fig. 3 is a detached elevational view of
the valve proper.
The body or casing a, a of the valve is cast or made in a cylindrical form about
twice the diameter of the bore b, of the pipe, or rather larger, and at right angles
thereto, and is fitted inside with a fixed cylindrical shell e, e closed at both ends and of
lesser diameter so as to leave an annular passage d, d all round excepting on the inlet side
where the bore b, b of the pipe is contracted and communicates with an opening e, e in
the shell, so as to admit steam into the interior thereof (see Fig. 2) the hore b, bat
the outlet side communicating with the annular passage d, d before mentioned. Inside
this fixed shell e, e which is made like a cylindrical grid with alternate bars and spaces,
is mounted the valve (see detached view Fig. 3) which is formed as follows:-Upon
the valve spindle (which passes through a stuffing box) we fix two discs, fit-
ting inside the ends of the cylindrical shell e, e and connected to each other by a series
of longitudinal bars h, having spaces i, i left between them so as to form a kind of
cylindrical grid corresponding with the shell c, c. The ends of these bars h, are let
into notches in the circumference of the two discs g, y and a certain amount of play is
allowed thereto so that the outward pressure of the steam presses them against the
inside of the fixed shell, e so as to make a good joint. The fixed shell is also
provided as before stated with longitudinal openings or slits corresponding with the
spaces i, between the bars h, and it will be evident that a very slight rotary move-
ment of the valve (imparted by the governor to a lever k, fixed on the valve spindle)
will open or close the several apertures or slits the full length of the shell c, c and thus
admit or cut off the full amount of steam quickly.
As a modification we propose sometimes to make the apertures or slits in both the
shell and the valve in a diagonal, instead of a longitudinal form, and as a further modi-
fication they may be made in a circumferential direction, but in the latter case the
valve would have to move in a longitudinal direction (instead of revolving) to open or
close the apertures.

page_text: Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed we declare that what we claim is:-
First. In a regulating valve for Steam Engines the combination with a cylindrical
body or casing at right angles to the steam pipe and of larger dimensions, of an
internal cylindrical grid or shell, inside which works a cylindrical grid-shaped valve,
the inlet box of the pipe communicating with the interior of the valve and the outlet
bore of the same communicating with the space between the body or casing and the
outside of the cylindrical grid or shell; all being constructed and operating substan-
tially as hereinbefore described and illustrated by the drawings annexed.
Secondly. We claim: In a regulating valve for Steam Engines constructing a cylin-
drical grid-shaped valve with loose bars, in order that the pressure of the steam may
cause them to make a perfect joint with the bars of the cylindrical casing or gril
inside which they work."

The body or casing a, a of the valve is cast or made in a cylindrical form about
twice the diameter of the bore b, of the pipe, or rather larger, and at right angles
thereto, and is fitted inside with a fixed cylindrical shell e, e closed at both ends and of
lesser diameter so as to leave an annular passage d, d all round excepting on the inlet side
where the bore b, of the pipe is contracted and communicates with an opening e, e in
the shell e, e so as to admit steam into the interior thereof (see Fig. 2) the bore b, bat
the outlet side communicating with the annular passage d, d before mentioned. Inside
this fixed shell e, which is made like a cylindrical grid with alternate bars and spaces,
is mounted the valve (see detached view Fig. 3) which is formed as follows:-Up
the valve spindle (which passes through a stuffing box) we fix two dises fit-
ting inside the ends of the cylindrical shell c, e and connected to each other by a series
of longitudinal bars, having spaces i, i left between them so as to form a kind of
cylindrical grid corresponding with the shell c, c. The ends of these bars h, are let.
into notches in the circumference of the two dises, and a certain amount of play is
allowed thereto so that the outward pressure of the steam presses them against the
inside of the fixed shell e, e so as to make a good joint. The fixed shell
provided as before stated with longitudinal openings or slits corresponding with the
spaces, between the bars h, and it will be evident that a very slight rotary move-
ment of the valve (imparted by the governor to a lever k, k fixed on the valve spindle)
will open or close the several apertures or slits the full length of the shell c, e and thus
admit or cut off the full amount of steam quickly.

internal cylindrical grid or shell, inside which works a cylindrical grid-shaped valve,
the inlet box of the pipe communicating with the interior of the valve and the outlet
bore of the same communicating with the space between the body or casing and the
