PROVISIONAL SPECIFICATION.
Improvements in or connected with Valves for Hot Gases.
We, JOSEPH VON LANGER, Engineer, and LEONARD COOPER, Iron Merchant, both
of 32, Park Row, Leeds, Yorkshire, do hereby declare the nature of this invention to
be as follows:-
My invention has for its principal object, to provide a valve suitable for
controlling or arresting the flow of hot water-gas from the producer to the
scrubber, but is generally applicable to stop-valves for hot gases or air.
The valve proper is a hollow disc or plate, preferably circular, and provided with
a hollow rim or flange adapted to dip into an annular cup containing a suitable liquid
or solid packing material. This valve is mounted on a hollow vertical spindle which
receives cold water at the lower end by means of a flexible pipe and discharges it at
the top through another flexible pipe. The interior of the spindle communicates with
the interior of the valve and supplies the latter with cooling water. The valve casing
is composed of the lower part or casing proper which contains the gas inlet situated
below the annular cup mentioned above, and the outlet situated above the same, as
well as the said annular cup itself, the valve chamber, and a stuffing box for guiding
the lower part of the valve spindle. The upper part consists of a lid or cover for the
valve chamber, a stuffing box for guiding the upper part of the valve-spindle, and an
open water receptacle which surrounds the said stuffing box. The lower part or
casing proper is provided with a closed receptacle for cooling water, which surrounds
the gas inlet, the valve chamber, the gas outlet and the lower stuffing box. The hot gas
enters radially into the lower part of the valve casing, then passes upwards into the
valve chamber and then radially outward. This course may, however, be reversed,
the inlet being at the top and the outlet at the bottom.
The cooling water enters through a pipe at the bottom of the valve casing, and is
discharged at the top of the said casing. The lid or upper part of the valve
casing is supplied with cooling water by means of a pipe dipping into the water
receptacle.

Improvements in or connected with Valves for Hot Gases.
We, JOSEPH VON LANGER, Engineer, and LEONARD COOPER, Iron Merchant, both
of 32, Park Row, Leeds, in the County of York, do hereby declare the nature of this
invention and in what manner the same is to be performed, to bo particularly
described and ascertained in and by the following statement :-
My invention has for its principal object, to provide a valve suitable for controlling
or arresting the flow of hot water gas from the producer to the scrubber, but it is
generally applicable to stop valves for hot gases or air.
in the accompanying drawings, Fig. I is a vertical section, Fig. 2 an elevation
and Fig. 3 a horizontal section and Fig. 4 a plan of a valve embodying this
invention.
The valve proper is a hollow disc or plate A, preferably circular. It may be
provided with a hollow rim or flange adapted to dip into an annular cup containing
a suitable liquid or solid packing material. This valve is mounted on a hollow vertical
spindle or on a pair of spindles a, a which receive cold water at the lower end by
means of a flexible pipe a¹ and discharges it at the top through another flexible pipe a².

page_text: The interior of the spindle communicates with the interior of the valve and supplies
the latter with cooling water. The valve casing chiefly consists of the cast iron
body B or casing proper, which contains the valve seat, the gas inlet & situated above
the valve seat, and the outlet & situated below the same, as well as the valve chamber b
and a stuffing box for guiding the lower part of the valve spindle. This casting is
open at the top and covered by a lid C provided with a stuffing box c for guiding the
upper part of the valve-spindle, and with an open water receptacle c¹ which surrounds
the said stuffing box. The casing or cast iron body B is provided with a closed
jacket or receptacle B' for cooling water, which surrounds the gas inlet, the valve
chamber, the gas outlet and the lower stuffing box. The bottom of the receptacle B¹
is perforated and provided with a lid D. The hot gas enters radially into the upper
part of the valve casing, then passes downward into the valve chamber and then
radially outward. This course, may however, be reversed, the inlet being at the
bottom and the outlet at the top.
The cooling water is admitted through the lid D by means of a pipe E, and is
discharged near the top of the jacket B₁ through a pipe E. This pipe extends
upward above the top of the receptacle c' and terminates in a double elbow connection
which leads the water downward through a pipe E2, while the steam which has been
mixed with the water, escapes upward through a pipe e. A small branch pipe e
supplies water from the discharge pipe E¹ to the open receptacle c¹. e² is a stay for
securing the discharge pipe E, to the casing c¹.
The horizontal section Fig. 3 is taken partly through the gas inlet and partly
through the gas outlet. In the plan Fig. 4 one half of the lid C is removed, to show
the apertures in the top of the jacket B'.
The pipes a and E are connected with a continuous supply of cold water
or other suitable liquid, so as to establish a constant circulation of cooling
liquid.
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 apparatus for controlling the flow of hot gases or air, the combination of a
hollow valve, with a hollow valve spindle or a pair of hollow spindles forming
a continuous passage through the valve, a valve casing adapted to guide the said
spindle or spindles, and a pair of flexible pipes connected with the ends of the valve
spindles, one serving to supply cooling liquid, and the other to discharge it,
substantially as described:
2. In apparatus for controlling the flow of hot gases or air, the combination of
a hollow valve, with a hollow vaive spindle or a pair of spindles extending on
opposite sides of the valve, a valve casing adapted to guide the said spindle or
spindles on opposite sides of the valve, a flexible water supply pipe connected with
one end of the spindle and a flexible water discharge pipe connected with the opposite
end of the spindle, substantially as described.
3. The combination of a lifting valve and valve spindle, with a valve box B, cooling
jacket B having lids C and D, water supply pipe E and water discharge pipe E¹,
substantially as described.
4. The combination of a lifting valve and valve spindle, with a valve box or
casing B, cover C baving a water receptacle c', cooling jacket B' having a lid D with
inlet pipo E, and a water outlet E, E, provided with branch pipe e¹ and steam vent e,
substantially as described.
