Improvements in Liquid Valves for Producer and other Gases
and Air.
i
I, JOHN WILLIAM WAILES, 'of The Cedars, Bescot Walsall in the County of
Stafford Engineer, do hereby declare the nature of this invention to be as follows:-
The main object of this invention is to provide valves which shall be simple in
construction, durable in use not liable to derangement, and which can be easily
operated to shut off or regulate the flow of gases or air.
For these purposes I form in the gas or air flue or in a vessel. placed therein a
depression similar to an inverted syphon or a downwards projecting piece and
provide an opening through which water or other liquid can be admitted to the said
inverted syphon or vessel so as to at will wholly or partially fill the depression and
thus cut off or diminish the flow of gas or air through the flue. When the water or
liquid is withdrawn from the depression the passage through the flue is free and
unobstructed.
In one modification a vessel has inlet and outlet pipes. Water is filled below the
level of those pipes. A cover dipping into the water has a downwards projecting
piece which when sealed with water prevents the passage of gas or on the other hand
allows gas to pass.
When several valves are used in conjunction, as in regenerative steel and other
furnaces I prefer to fill or seal one or more valves with the water or liquid which is
withdrawn from the other valves which are being opened.
.
In some instancos the water or liquid to seal the valves is supplied through a pipe
from a vessel by means of a displacer inserted in such vessel. When the displacer is
withdrawn the water or liquid will flow back from the valves to the vessel, from
which it may be discharged from time to time if required and a fresh supply admitted
to the vessel through a tap or valve.
COMPLETE SPECIFICATION.
Improvements in Liquid Valves for Producer and other Gases
and Air.
I JOHN WILLIAM WAILES of The Cedars Bescot, Walsall in the County of
Stafford, Engineer, 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:—
The main. object of. this invention is to provide valves which shall be simple in
construction, durable in use, not liable to derangement, and which can be easily
operated to shut off or regulate the flow of gases or air.
For these purposes I form in the gas or air flue or in a vessel placed therein a
depression similar to an inverted syphon or a downwards projecting piece and provide
an opening through which water or other liquid can be admitted to the said inverted
syphon or vessel so as to at will wholly or partially fill the depression and thus cut
off or diminish the flow of gas or air through the flue. When the water or liquid is
withdrawn from the depression the passage through the flue is free and
unobstructed.
In one modification a vessel has inlet and outlet pipes. Water is filled below the
level of those pipes. A cover dipping into the water has a downwards projecting

page_text: piece which when sealed with water prevents the passage of gas or on the other hand
allows gas to pass.
When several valves are used in conjunction, as in regenerative steel and other
furnaces I prefer to fill or seal one or more valves with the water or liquid which is
withdrawn from the other valves which are being opened.
In some instances the water or liquid to seal the valves is supplied through a pipe
from a vessel by means of a displacer.inserted in such vessel. When the displacer is
withdrawn the water or liquid will; flow, back from 'the valves to the vessel, from
which it. may be discharged from time to time if required, and a fresh supply admitted
to the vessel through a tap.or. valve.
DESCRIPTION' OF THE: DRAWINGS.
Fig. 1 is a longitudinal section of a range of valves under my invention, adapted
for use with a regenerative air and gas furnace, a a' are air valves, bbl.flue valves,
aecis a' double gas valve, d dare displacers, e el are pipes connecting the valves.a. b.
and c; and a¹; b and c to their respective displacers d.d.

: Fig 2is a transverse section of an air. or. flue valve.
Eig. 3is a plan, andi fig.,4 a transverse section of. the double gas valve.
It will be seen that as one. displacer is raised the other is lowered and the water
is caused to rise or fall in the valves. When the water rises in the valves..the
through way is closed as will be seen on reference to..the air or fluo valve. fig..2. It
will also be seen that when the water rises in one of the gas valve.boxes c it falls in
the other c', and vice versa, so that the passage of gas from the inlet. way f, is directed
through one or other of the boxes c c as desired, the closing of .the way, in either
direction/being effected by the water rising above the lower edges. of a diaphragm¨or
depression g. g².
Fig. 5 is a transverse section of a valve.in which the water or sealing, fluid is. held
in a container and the closing of the valve is effected by raising, the container to
the required hoight.
It will be obvious that many modifications of valves may, be made., under; my
sinvention, and that an essential feature is that there are no internal moving parts.to
get out of order.
Having now particularly described and ascertained the nature of my saidi Inven-
tion, and in what manner the same is to be performed I declare that what I
claim is ;-
A W
First. Valves for producer. and other gas and air having an inverted syphon or
depression, and means for admitting. a sealing liquid thereto substantially as set-
forth.
Second. Valves for air and gas having a downward projecting piece dipping into
a sealing fluid substantially as setforth.
"Third. A range of valves under my invention combined with displacers for sealing
liquid-substantially as setforth.
