CORK STRIPS FOR COVERING PIPES, RESERVOIRS, AND OTHER OBJECTS to be ass
Year: 1884

page_text: I, JULES BOURDON, of 36 Boulevard Voltaire, in the city of Paris, France,
Manufacturer, do hereby declare the nature of my invention for "CORK STRIPS FOR
COVERING PIPES, RESERVOIRS, AND OTHER OBJECTS to be as follows:-
"
Cork has already been applied as a non-conductor of heat for covering steam, air,
or hot gas pipes or vessels, and also for boilers, and generally for all surfaces through
which it is desired to prevent heat or cold passing. It has always been employed
in the form of sheets or picces united in various manners; but the number of pieces
in itself and the necessarily imperfect connection constitute a cause of rapid
deterioration.
My invention has for its object the application to the purposes above referred to,
of cork in the form of a continuous ribbon. This ribbon is formed of a strip of
cork of any suitable length, width and thickness, and covered by a fabric, which is
stuck on to the cork by one or several layers of a special cement, which is very
adhesive and impermeable, and consists of a solution of india rubber or caoutchoua
in a suitable solvent.
This ribbon is prepared in the following manner :-
The raw cork is shaped into strips of the desired width by means of one of the
tools employed for this purpose in working cork. These strips are again cut by
the same means, in the direction of their thickness, so as to reduce them to the
required thickness. In order to produce a ribbon of any determined length the ends
of the strips are bevelled, and the different strips united by sticking them together
with the solution of india rubber. The fabric is then covered with the cement or
solution of india rubber and applied to the cork. The strip of fabric, which may be of
great length, therefore, assists in binding the different elements or parts of the cork
ribbon together. Any fabric may be employed and the cork ribbon may be covered
therewith either upon one side only or upon both sides. The ribbon may further be
made up of two or more layers of cork superposed, and, a fabric, or any other
material (either non-conducting or not) may be interposed between the different
layers.
The ribbons of cork thus obtained may be employed for a variety of purposes, of
which the principal are:-
The covering of pipes, reservoirs, and other apparatus for conveying or holding
steam, water, air, hot gases, and other substances,

page_text: The covering of domestic and cooking utensils, and generally for covering
surfaces of all kinds with a non-conducting material so as to prevent loss of heat.
They may also be employed in electrical apparatus; for bell-glasses in order to
guard against breakage; for decorating rooms, walls, doors and windows; for the
manufacture of life buoys; for packing, and generally in all cases where it is
required to cover any object with a layer of cork.
The fixing is extremely simple and may be effected by any ordinary workman.
Supposing it is required to cover a tube with the cork ribbon described :-
One strip is wound round the tube in the form of a helix, thon a second strip is
wound over the first, care being taken that it covers the joints of the latter. The
operation is completed by sticking a fabric outside, which hides the joints of the
last strip.
It is evident that either a single strip or more than two of them may bo
employed if desired.

I, JULES BOURDON, of 36 Boulevard Voltaire, in the city of Paris, France,
Manufacturer, do hereby declare the nature of my invention for "CORK STRIPS FOR
COVERING PIPES, RESERVOIRS, AND OTHER OBJECTS" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :—
Cork has already been applied as a non-conductor of heat for covering steam, air, .
or hot gas pipes or vessels, and also for boilers, and generally for all surfaces through
which it is desired to prevent heat or cold passing. It has always been employed
in the form of sheets or pieces united in various manners; but the number of pieces
in itself and the necessarily imperfect connection constitute a cause of rapid
deterioration.
My invention has for its object the application to the purposes above referred.to,
of cork in the form of a continuous ribbon. This ribbon is formed of a strip of
cork a of any suitable length, width and thickness, and covered by a fabric b,
which is stuck on to the cork by one or several layers of a special cement, which is
very adhesive and impermeable, and consists of a solution of india rubber or
caoutchouc in a suitable solvent.
This ribbon is prepared in the following manner :-
The raw cork is shaped into strips of the desired width by means of one of the
tools employed for this purpose in working cork. These strips are again cut by the
same means, in the direction of their thickness, so as to reduce them to the required
thickness. In order to produce a ribbon of any determined length the ends c, c,
(Fig. 1) of the strips are bevelled, and the different strips united by sticking them
together with a solution of india rubber. The fabric is then covered with the
cement or solution of india rubber and applied to the cork. The strip of fabric,
which may be of great length, therefore, assists in binding the different elements or
parts of the cork ribbon together. Any fabric may be employed and the cork ribbon
may be covered therewith either upon one side only or upon both sides. The ribbon
may further be made up of two or more layers of cork superposed, and a fabric, or
any other material (either non-conducting or not) may be interposed between the
different layers.
The ribbons of cork thus obtained may be employed for a variety of purposes, of
which the principal are:-
The covering of pipes, reservoirs, and other apparatus for conveying or holding
steam, water, air, hot gases, and other substances.
The covering of domestic and cooking utensils, and generally for covering
surfaces of all kinds with a non-conducting material so as to prevent loss of heat.
They may also be employed in electrical apparatus; for bell-glasses in order to
guard against breakage; for decorating rooms, walls, doors and windows; for the
manufacture of life buoys; for packing, and generally in all cases where it is
required to cover any object with a layer of cork.
The fixing is extremely simple and may be effected by any ordinary workman.
Supposing it is required to cover a tube T with the cork ribbon described :-

page_text: then a second strip a¹ is wound over the first, care being taken that it covers the
joints d, d, of the latter. The operation is completed by sticking a fabric e outside,
so as to cover the joints of the last strip.
It is evident that either a single strip or more than two of them may be
employed if desired.
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. The application of. cork in the form of continuous ribbons in all cases where it
is desired to cover any object with a layer of cork, and principally in covering pipes
or reservoirs for steam, gas, hot air or other substances.
2. The manufacture of a continuous ribbon of cork by means of strips with
bevelled ends, which are stuck. together end to end, and covered with a fabric
either upon one or upon both sides, the glue or cement employed being preferably
formed of a solution of india rubber, the ribbons thus formed being capable of
application to a variety of uses, and principally as an envelope or surface which is
a non-conductor of heat.
