ALFRED GEORGE BROOKES of 55 & 56 Chancery Lane in the County of
London, Chartered Patent Agent do hereby declare the nature of this invention
to be as follows:-
This invention has for its object the production of a steam valve provided with a
removeable seat the seat being preferably constructed in tube form, perforated and
provided with suitable means of fastening same at the lower or outer end to the
valve case or chamber, so that it can be taken out of the valve without opening the
valve box cover.
Steam or like valves known at present in use have the disadvantage that it is
difficult to get at the seat of the valve, the distance between the latter and the
cover of the valve chamber being too great. It is therefore always difficult to
readjust a steam or like valve. Steam and like valves into which the seat is
introduced from the top present the same difficulty i.e. to get the seat fastened
tightly to the part of the chamber to which they have to be attached.
To avoid these disadvantages the present steam or fluid valve has an opening at
the rear or opposite side to the stem into which the seat is put.
According to one embodiment of this principle of construction the valve
chamber is provided with a conical opening at the back, into which the valve seat
is introduced. The valve cone which must be attached to a spindle is shaped in
such manner, that it glides from the side over the lower knob or head of the
spindle and is thus moved up and down with the screwing of the spindle.
In the first place the valve cone is put in its position and then through the
same opening the seat of the valve is put into the chamber and finally fastened by
screws.
If an inspection of the valve becomes necessary, all that is needed is to loosen
screws and by screwing down the spindle the cone presses upon the seat pushing it
out of the valve chamber. The valve itself is left in its position in the conduit
of pipe.

COMPLETE SPECIFICATION.
Improvements in Valves for Controlling the Passage of Fluids.
A communication from abroad by the Firm of MAX GREEVEN AND Co., of
Crefeld, in the German Empire, Engineers.
I, ALFRED GEORGE BROOKES, of 55 & 56 Chancery Lane, in the County of
London, Chartered Patent Agent, 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 for its object the production of a steam valve provided with a
removable seat the seat being preferably constructed in tube form perforated and
provided with suitable means of fastening same at the lower or outer end to the

page_text: valve without opening the
valve box cover.
Steam or like valves known at present in use have the disadvantage that it is
difficult to get at the seat of the valve the distance between the latter and the cover
of the valve chamber being too great.
It is therefore always difficult to readjust a steam or like valve. Steam and like
valves into which the seat is introduced from the top present the same difficulty
i.e. to get the seat fastened tightly to the part of the chamber to which they have
to be attached.
To avoid these disadvantages according to the present invention the improved
steam or fluid valve has an opening at the rear or opposite side to the stem into
which the seat is put.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 shews a vertical section of a steam valve according to one embodiment of
this principle of construction.
Fig. 2 shews by sectional view and Fig. 3 by plan the plug D separately,
shewing the form of the part d thereof for grasping the end of the spindle C.
The valve chamber A is provided with a conical opening at the back, into which
the valve seat B is introduced.
The valve cone D which for use must be attached to a spindle C is shaped in
such a manner (see Figs. 2 and 3) that it slides from one side over the lower knob
or head of the spindle C and when so engaged is moved up and down with the
screwing down and unscrewing of the spindle C.
In the first place the valve cone is put in its position as already described and
then through the same opening the seat of the valve is put into the chamber and
finally fastened by screws s, §. If an inspection of the valve becomes necessary,
all that is needed is to loosen screws s, sand by screwing down the spindle the cone
presses upon the seat pushing it out of the valve chamber. The valve D itself is
left in its position in the conduit or channel through the valve.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is
1. The construction and use of a steam or other fluid valve provided with a
removable seat which seat is of substantially tubular form, perforated and provided
with suitable means of fastening the same at the lower or outer end of the valve
case or chamber, with capability of removal of the valve without opening the valve
box cover substantially as set forth.
2. The construction and combination of parts of a steam or fluid valve so that the
tubular valve seat thereof may be removable as and for the purpose set forth.
Dated the 14th day of October 1893.
