I, WILLIAM HENRY EMPSALL, Brassfinisher, of Bradford, in the county of York,
do hereby declare the nature of iny said Invention to be as follows:-
This Invention relates to certain improvements in or connected with the seatings of
steam valves.
The seatings of such valves have been hitherto adapted to the part to which they
are connected by being screwed thereinto. This connection at times causes a difficulty
in properly adjusting the seating, and it is among the objects of the present Invention
to obviate this difficulty and to provide improved facilities of removing the valve
seating when desired.
In accordance with the present improvements, the valve seating is formed as a
skeleton plug which is adapted to the part to which it is desired to be connected and
is secured in position by a set screw which is passed through the connection and is
inserted into the bottom part of the plug and so holds it down upon its seating. The
parts of the plug which rest upon the said connection are truly turned or formed to
prevent passage or escape of steam, and the skeleton formation of the plug or seating
permits of the free passage of the steam when the valve lifts or is lifted therefrom.

page_text: I, WILLIAM HENRY EMPSALL, Brassfinisher, of Bradford, in the County of York,
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
statenient :-
This Invention relates to certain improvements in or connected with the seatings of
steam or water valves.
The seatings of such valves have been hitherto adapted to the part to which they
are connected by being screwed thereinto. This connection at times causes a difficulty
in properly adjusting the seating, and it is among the objects of the present Invention
to obviate this difficulty and to provide improved facilities of removing the valve
seating when desired.
In accordance with the present improvements, the application of which is illustrated
on the accompanying drawings, the valve-seating 1, is formed with a bridge piece, 2,
formed with lateral through openings, 3, for allowing of the free passage of the steam
or water when the valve lifts or is lifted and its periphery at, 4, is adapted to the part
of the casing, 5, upon which it rests or to which it is desired to be connected, by being
truly turned or formed so as to prevent the passage or escape of the steam or water
between such parts, and it is secured in position by a removable screw or set screw, 6,
which is passed through the valve casing, 5, and is inserted into the said bridge-
piece, 2, of the valve seating, and so holds the latter down in its desired position as
illustrated until it is required to be removed for repair or renewal of the working
parts, and which can be effected according to the present improvements without
disturbing the connected pipes or fixings, it being only necessary, in order to remove
the seating, to loosen the screw, 6, and by tapping thereon to remove the scat from its
normal position, and after removing the screw, 6, the seating can be removed through
the opening in the casing normally occupied by the stuffing box.
Fig. 1, represents, in sectional elevation, the application of the Invention to a steam
or water valve, and Fig. 2, represents the valve parts detached.
Having thus described the nature of my said Invention, and in what manner the
same is to be performed, I declare that what 1 claim is,
The hereinbefore described improvements in or connected with the seatings of steam
or water valves.
