Pipes at a Distance by means of Air Pressure.
I, NICOLAUS BECKER, of 5-7, Kleine Schifferstrasse, Saxenhausen, Frankfort-on-
the-Main, in the Empire of Germany, Manufacturer, do hereby declare the nature of
this invention to be as follows:-
This invention has for its object an arrangement for opening and closing low
pressure supply pipes in place of the ordinary taps from a point at a distance from
the places of consumption of the substance conveyed (gas, water, steam and the like)
and is designed to effect the opening or closing of the pipe or pipes by means of air
pressure.
A form of construction of this invention is shown in the accompanying drawings
in which Figure 1 is a side view and Figure 2 a plan view.
A is the supply pipe for gas, water, steam or the like, whilst B is the actual device
for opening and closing this pipe by means of air pressure.
In the example shown in the drawings, this device consists of a suitably shaped
enlargement of the pipe or a box inserted therein, in the interior of which enlarge-
ment or box a flat bladder C of indiarubber or the like, capable of being inflated by
air pressure, is mounted by means of a gas tight joint. The latter is connected
with a supply pipe D provided at some suitable point of the room in question with a
device E for introducing compressed air into the bladder C. In the example shown
in the drawings this device E consists of an indiarubber ball filled with compressed
air and mounted in a recess in a plate F in such a way that by passing over it a
dise G pivotally mounted on the plate, the indiarubber ball may be more or less com-
pressed as desired. The air thereby discharged from the ball passes through the
pipe D into the indiarubber bladder C inserted in the pipe A and inflates more or
less said bladder, thereby closing more or less the pipe A so that the supply of the
substance conveyed therein is entirely or partially interrupted.
Of course the pressure of the substance conveyed by the pipe A must not exceed
the inaximum pressure attainable in the indiarubber bladder, and the present inven-
tion is therefore mainly intended for use in gas pipes but may also be employed for
low pressure, water, steam and other pipes.
In place of the compressed air ball E shown in the drawings, a cylinder filled with
compressed gas or the like may be employed more particularly where the invention
is employed for several pipes from a central station, and in place of the indiarubber
bladder C directly effecting the closing of the pipe, mechanical aids connected
therewith, such for instance as stoppers or closing cones of indiarubber, metal or the
like mounted thereon, or valves operated by the air pressure may be employed.
All these forms of construction have one principle in common viz. that of closing
or opening pipes at a distance from some suitable point by means of compressed air.
The form of construction shown in the drawing is also particularly suitable for use
for lighting gas in chandeliers and the like, an electric igniting device or small
constantly burning pilot flame being employed which acts as follows. On the disc G

page_text: travelling completely over the compressed air ball E the indiarubber bladder C is
inflated in such a way that it presses tightly on all sides against the inside of the box
or chamber B and thus completely shuts off the gas and consequently extinguishes
the flame or flames, whilst by merely partly passing the disc G over the ball E a
suitable regulation of the size of the flame or flames is effected from a distance.
This invention thus affords a means of closing or opening pipes from any suitable
point, which is simple in handling and cheap, but yet thoroughly effective.

Improvements in Arrangements for Opening and Closing Supply
Pipes at a Distance by means of Air Pressure.
I, NICOLAUS BECKER, of 5-7, Kleine, Schifferstrasse, Saxenhausen, Frankfort-on-
the-Main, in the Empire of Germany, Manufacturer, 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 an arrangement for opening and closing low
pressure supply pipes in place of the ordinary taps from a point at a distance from the
places of consumption of the substance conveyed (gas, water, steam and the like) and
is designed to effect the opening or closing of the pipe or pipes by means of air
pressure.
A form of construction of this invention is shown in the drawings accompanying
the Provisional Specification, in which Figure 1 is a side view and Figure 2 a plan
view.
A is the supply pipe for gas, water, steam or the like, whilst B is the actual device
for opening and closing this pipe by means of air pressure.
In the example shown in the drawings, this device consists of a suitably shaped
enlargement of the pipe or a box inserted therein, in the interior of which enlarge-
ment or box a flat bladder C of indiarubber or the like, capable of being inflated by
air pressure, is mounted by means of a gas tight joint. The latter is connected with
a supply pipe D provided at some suitable point of the room in question with a
device E for introducing compressed air into the bladder C. In the example shown
in the drawings, this device E consists of an indiarubber ball filled with compressed
air and mounted in a recess in a plate F in such a way that by passing over it a
disc G pivotally mounted on. the plate, the indiarubber ball may be more or less
compressed as desired. The air thereby discharged from the ball passes through the
pipe D into the indiarubber bladder Cinserted in the pipe A and inflates more or
less said bladder, thereby closing more or less the pipe A so that the supply of the
substance conveyed therein is entirely or partially interrupted.
Of course the pressure of the substance conveyed by the pipe A must not exceed
the maximum pressure attainable in the indiarubber bladder, and the present inven-
tion is therefore mainly intended for use in gas pipes but may also be employed for
low pressure, water, steam and other pipes.
In place of the compressed air ball E shown in the drawings, a cylinder filled with
compressed gas or the like may be employed more particularly where the invention
is employed for several pipes from a central station, and in place of the indiarubber
bladder C directly effecting the closing of the pipe, mechanical aids connected there-
with, such for instance as stoppers or closing cones of indiarubber, metal or the like
mounted thereon, or valves operated by the air pressure may be employed.

page_text: All these forms of construction have one principle in common, viz. that of closing
or opening pipes at a distance from some suitable point by means of compressed air.
The form of construction shown in the drawing is also particularly suitable for use
for lighting gas in chandeliers and the like, an electric igniting device or small con-
stantly burning pilot flame being employed which acts as follows. On the disc G
travelling completely over the compressed air ball E the indiarubber bladder C is in-
flated in such a way that it presses tightly on all sides against the inside of the box
or chamber B and thus completely shuts off the gas and consequently extinguishes
the flame or flames, whilst by merely partly passing the disc G over the ball E a suit-
able regulation of the size of the flame or flames is effected from a distance.
This invention thus affords a means of closing or opening pipes from any suitable
point, which is simple in handling and cheap, but yet thoroughly effective.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. An arrangement for opening and closing, by means of compressed air from a
distance, low pressure pipes for conveying gas, water, steam and the like, in which
arrangement the closing or opening of the pipe (A) is effected by means of a bladder,
of indiarubber or the like, fitting tightly against the inside of a box or chamber (B)
inserted in the said pipe; substantially as herein before described and shown in the
drawings.
2. In an arrangement for opening and closing by means of compressed air from a
distance low pressure pipes for conveying gas, water, steam or the like, the inflation
of the indiarubber or the like bladder (B) by means of a pipe suitably connected
therewith and a compressed air ball (E) arranged at any suitable place, substantially
as hereinbefore described and shown in the drawings.
