page_text: LETTERS PATENT to Benjamin Rhodes of Bow Road London. E: Engineer and
Brassfounder for an invention of "IMPROVEMENTS IN THE MANUFACture of
TUBES TO BE USED EITHER FOR THE INTERNAL LINING OR THE EXTERNAL
COVERING OR CASING OF OTHER PIPES, OR TUBES OR TO BE USED ALONE
AS PIPES OR TUBES

PROVISIONAL SPECIFICATION left by the said Benjamin Rhodes at the
Office of the Commissioners of Patents on the 22nd May 1882.
BENJAMIN RHODES of Bow Road, London E.-Engineer and Brassfounder-
"IMPROVEMENTS IN THE MANUFACTURE OF TUBES TO BE USED EITHER FOR THE
INTERNAL LINING, OR THE EXTERNAL COVERING OR CASING OF OTHER PIPES, OR
TUBES OR, TO BE USED ALONE AS PIPES OR TUBES
"
In carrying out my Invention, I take sheets of Asbestos paper or cloth, and
prepare the surface with a glutinous size or other suitable adhesive material, either
by immersion or otherwise; I then coil or roll up the said sheets upon a mandril
of any desired size; and, when the tube formed on it is sufficiently set and dry, I
withdraw the mandril, and the tube or pipe is ready to be used for the following
amongst other applications: that is to say, as a fireproof liming for the interior of
metal tubes, and in covering the same where they are exposed to great heat as in
the case of the ventilating tubes employed to carry off the vitiated air in rooms
where gas is employed: and, similarly the said tubes may be used with great
advantage in Chemical Works owing to their withstanding the injurious action of
chemical Vapours or liquids; as also, in the cases of highly heated vapours or
liquids.
.
When the said tubes are used alone, they may be used with advantage for the
following amongst other purposes; namely, as tubular non-conducting or insulating
channels for enclosing Electric wires; for air passages in organs; for speaking
tubes, and for various other purposes

In carrying out my Invention I take sheets of asbestos paper or cloth and
prepare the surface with a glutinous size or other suitable adhesive material, either
by immersion or otherwise. I then coil or roll up the said sheet upon a mandril
of any desired size, and when the tube formed on it is sufficiently set and dry, I,
withdraw the mandril, and the tube or pipe is ready to be used for the following
amongst other applications, that is to say as a fire proof lining for the interior of
metal tubes, and in covering the same when they are exposed to great heat as in
the case of the ventilating tubes employed to carry off the vitiated air in rooms
where gas is employed: And, similarly the said tubes may be used with great
advantage in Chemical Works owing to their withstanding the injurious action of
chemical vapours or liquids: as also in the cases of highly heated vapours or
liquids.
When the said tubes are used alone, they may be used with advantage for the
following amongst other purposes namely as tubular non-conducting or insulating
channels for enclosing Electro wires: for air passages in organs, for speaking tubes
and for various other purposes.
In making tubes in accordance with my invention to be used as a lining or
casing to metal tubes, and to protect other metal surfaces against oxidation which
are subjected to heat, such as gas ventilating tubes, I take sheets of asbestos paper
or cloth which I cause to be pressed by means of rollers to be tightly wound
around a mandril until a tube of the requisite thickness is attained when the said
tube thus formed is cut off and the mandril is withdrawn-The tube when
removed is then placed in a drying chamber and allowed to remain until
sufficiently hardened.
When the tubes formed in accordance with my invention are to be employed by
themselves independantly such as for instance as insulated electric wires I saturate
the asbestos sheet previous to coiling in a waterproof solution consisting of shellac
india rubber or gutta percha dissolved in alcohol.
Having now described the nature and objects of my said Invention, I wish it to
be understood that I claim as follows:
1st The novel composition of materials herein described and defined
2nd The use of asbestos paper or asbestos woven cloth for the formation of tubes
to be used for the various purposes herein described and set forth.
:
In witness whereof I the said Benjamin Rhodes have hereunto set my hand
and seal this twenty first day of November in the year of our Lord one
thousand eight hundred and eighty two..
