An Improved Device for Opening and Closing Low-pressure Conduits

This invention relates to a device for opening and closing low-pressure con-
duits for gas or other fluid or liquid (hereinafter referred to as gas") from a
distant point of actuation by means of the compression or exhaustion of air or
other fluid or liquid (hereinafter referred to as air"), and is characterized by
the provision, at a suitable point in the gas conduit, of a chamber connected
both to the through-way of such conduit and to the supply of the controlling
air, and of a piston having a flow-through channel serving to communicate with
the conduit through-way and adapted to work hermetically in the chamber cross-
wise of the conduit through-way and to be moved with its flow-through channel
into or out of communication with the conduit through-way by the compression
or exhaustion of the controlling air acting in the chamber, as hereinafter more
particularly described in constructional form as applied to a burner or gas
conduit.
The burner is adapted to be screwed onto a gas supply-pipe, and is formed with
two through-ways or passages crossing each other at right angles.
One of such through-ways serves for the passage of the gas to the point of
ignition or use, and the other through-way serves to receive a piston having a
peripheral groove, and by means of which the passage of the gas through the
conduit through-way is permitted or prevented, as required.
One end of the piston through-way is closed by a suitably packed coupling and
communicates with suitable air supply and exhaust apparatus by a pipe, while
the other end of such through-way is closed by a suitably packed cap and com-
municates with the outlet part of the gas through-way by a duct made in its
upper part.
When it is desired to permit of the passage of the gas through the conduit,
air is forced through the said pipe into the adjacent end of the piston chamber
and causes the piston to asume a position which allows of the gas passing its
peripheral groove; and, when it is desired to prevent the passing of the gas
through the conduit, air is exhausted from the piston chamber through the said
pipe, when the atmospheric pressure acting on the other end of the piston causes
the latter to assume a position which prevents the gas from passing the piston
peripheral groove.
From the lower part of the conduit through-way, a pipe leads to the igniting
device-which consists of a gas nozzle above which is fitted an air and gas mixing-
tube having an air inlet and fitted at its top with a removable burner (or there
formed as a burner) having a less bore than that of the mixing-tube to prevent
the "Bunsen "Hame from striking back."

for Gas or other Fluid or Liquid from a Distant Point of Actuation.
I, CONRAD ADOLF WEBER-MARTI, of 3, Streulistrasse, Zurich, Switzerland,
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:-
-
This invention relates to a device for opening and closing low-pressure con-
duits for gas or other fluid or liquid (hereinafter referred to as "gas") from a
distant point of actuation by means of the compression or exhaustion of air or
other fluid or liquid (hereinafter referred to as "air"), and is characterized by
the provision at a suitable point in the gas conduit of a chamber connected
both to the said gas conduit and the atmosphere by a particular duct and to the
supply of the controlling air, and of a piston having a flow-through channel to
communicate with the through-way of the conduit and adapted to work her-
metically in the chamber cross-wise of the conduit through-way and to be moved
with its flow-through channel into or out of communication with the conduit
through-way by the compression or exhaustion of the controlling air acting in
the chamber, respectively by the action of the atmosphere..
In the accompanying drawing which forms a part of this specification and
which represents the invention applied to an acetylene gas burner,-
Figure 1, represents the device in sectional elevation, showing the same open
for the through passage of the
gas;
T
Fig. 2, represents the device in a like view, in part, showing it closed so as
to prevent the through passage of the gas; and
Fig. 3, represents a side elevation, partly in section.
b, represents a gas conduit, which is adapted, at a, to be screwed onto augas.
supply-pipe, and is formed with two through-ways or passages, c, d, crossing
each other at right angles.
The through-way, c, serves for the passage of the gas to the point of ignition
or use, and the througli-way, d, serves to receive a piston, 'f, having a peripheral
groove, e, and by means of which the 'passage of the gas through the through-
way, c, is permitted or prevented, as required.
One end of the through-way, dis closed by a coupling, m, having suitable
packing, m; and communicates with suitable air supply and exhaust apparatus
(not shown) by a pipe, k, while the other end of such through-way is closed by
a cap, h, having suitable packing, ', and communicates with the outlet passages c,
and the atmosphere, by a duct, g, made in it's upper wall.
When it is desired to permit of the passage of the gas through the channel, c,
air is forced through the pipe, k, into the adjacent end of the chamber, d, and
causes the piston, f, to assume the position indicated in Fig, 1 which allows
of the gas passing the peripheral channel, e; and, when it is desired: to prevent
the passing of the gas through the channel, c, air is exhausted from the
chamber, d, through the pipe, k, when the atmospheric pressure acting on the
other end of the piston causes the latter to assume the position indicated in
Fig. 2. which prevents the gas from passing the peripheral channel, e.
From the lower part of the through-way, e, a conduit, 7, leads to the igniting
device which consists of a gas nozzle, », above which is fitted an air and gas
mixing-tube, p. having an air inlet, o, and fitted, at its top, with a removable
burner, q. (or there formed as a burner) having a less bore than that of the
mixing-tube to prevent the "Bunsen flame from "striking back."

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
(1). In apparatus for opening and closing low pressure conduits from a distant
point of actuation, in combination, a conduit for the gas or other fluid or liquid
to be controlled, a chamber, d, intercepting the conduit through-way and always
communicating at one of its ends with such through-way by means of a duct, g,
made in the upper wall of the chamber, a piston, f, serving to close such through-
way and having a flow-through channel, e, serving to open such through-way
and adapted to work hermetically in the chamber, d, cross-wise of the conduit,
and means in connection with the other end of the chamber to that lastly referred
to for forcing air or other liquid or fluid thereinto and exhausting the same
therefrom so as to operate the piston, as set forth.
(2). In apparatus for opening and closing conduits from a distant point of
actuation, in combination, a conduit for the gas or other fluid or liquid to be

in the upper wall of the chamber, a packed cap, h', serving to close such end of
the chamber, a packed coupling, m, serving to close the other end of the chamber,

channel, e, serving to open such through-way and adapted to work hermetically
in the chamber, d, cross-wise of the conduit, and means in connection with the
coupling-fitted end of the chamber for forcing air or other fluid or liquid there-
into and exhausting the same therefrom so as to operate the piston, as set forth.
