do hereby declare the nature of this invention to be as follows:-
Flexible gas tubing, as at present made, has one great disadvantage, viz. :—that the
gas permeates through the material of which the tubing is composed, and escapes into
the room.
Many attempts have been made to produce an inodorous gas tubing, but hitherto
without any satisfactory results.
Now the object of my invention is to produce such an inodorous gas tubing.
In carrying out my invention, I form my tubing of india rubber or other material
in the well known manner, and I insert therein the spiral wire, as hitherto.
I next line the tubing thus formed, with a flexible metal tube, such as that known
as pneumatic tubing, and I solder the ends of this tube to the brass nozzles.
The metal which I prefer to use for the tubing is lead, but I may also use
composition tubing.
The metal tubing is perfectly impervious to the gas, and by soldering the ends of
the metal tubing to the nozzles, I prevent the gas passing between the lining and the
india rubber.
By these means I obviate the difficulty hitherto experienced with flexible gas
tubing.
The flexibility of the tubing is in no way interfered with by the metal lining, and
the lining is preserved from breaking by the wire, which ensures the tube bending
only in the arc of a circle.

Improvements in Flexible Gas Tubing.
I DAVID WILLIAM SUGG of Vincent Street in the City of Westminster, 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 :-
Flexible gas tubing hitherto used has one great disadvantage, viz., that the gas
permeates the material of which the tubing is composed, and causes it to smell.
Many attempts have been made to produce an inodorous gas tubing but hitherto
without any satisfactory results.
Now the object of my invention is to produce such an inodorous gas tubing.
In carrying out my invention, I adopt any of the gas tubings now in use, but prefer
those in the manufacture of which a spiral wire is employed.
This tubing I line with a flexible inetal tube, such as that known as pneumatic
tubing, and I solder the ends of this tube to the brass nozzles of the gas tube..
The tubing which I prefer to use for my purpose is drawn lead tube, but I may
also use composition.
The metal tubing is perfectly impervious to the gas, and by soldering the ends of
the metal tubing to the nozzles, I prevent the gas passing between the lining and the
india rubber.
By these means I obviate the difficulty hitherto experienced with flexible gas
tubing.
.
The flexibility of the tubing is in no way interfered with by the metal lining, and
the metal lining is preserved from breaking by the wire which ensures the tube
bending only in the arc of a circle.
In the accompanying drawing, I have shown, at Fig. 1, a longitudinal section, and at
Fig. 2 a cross section, of a piece of gas tubing constructed according to my invention.
A is the outer tube of ordinary gas tubing of any kind; B is the spiral wire, and
C the metal lining. D is a nozzle at the end of the tubing, to which the lining is
soldered.
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
The production of inodorous gas tubing by combining with any ordinary gas tubing
a lining of drawn lead or other flexible tube, substantially as shown and described.
