PROVISIONAL SPECIFICATION.
An Improvement in Coverings and Linings for Lessening Conduction
of Heat.
We, HENRY PERCY IBOTSON, of 23 Gunterstone Road, West Kensington, in
the County of London, Works Manager, and GEORGE WILLIAM GILES of
18 East Dulwich Grove, in the County of Surrey, Secretary, do hereby declare
the nature of this invention to be as follows:-
This invention relates to coverings or linings to be applied to pipes or vessels for
lessening conduction of heat to or from the material within them.
For this purpose we coat with adhesive material such as silicate of soda solution
a sheet of canvas or other fabric and on the coated surface we lay at small intervals
apart parallel to each other loose ropes formed by giving a slight twist to bundles
of asbestos fibres, which may in some cases have other fibres mixed with them.
These loose ropes are caused by the silicate coating to adhere to the fabric backing,
the whole constituting a protective covering which can be wrapped round pipes or
vessels or it may be a protective lining.
The rope form in which the fibres are laid and the small intervals between
them allow the covering to be readily wrapped around pipes even of small
diameter.
Instead of employing asbestos fibre, other fibres may be used in a similar way,
also powders which are bad conductors of heat, such as ground cork, infusorial
earth, or the like, can be moulded with agglutinating material into bars of
triangular or tapezoidal section and cemented by their bases on to a fabric
backing.
In applying the covering to a pipe, cylinder or the like, it is wrapped round and
the meeting edges are connected by stitching or in any other known manner.
A convenient mode of connecting them is to provide near each edge a row of
lacing hooks or studs rivetted in the fabric in the usual way, and then on bringing
the edges together to secure them by lacing with cord.

of Heat.
We, HENRY PERCY IBOTSON, of 23 Gunterstone Road, West Kensington,
in the County of London, Works Manager, and GEORGE WILLIAM GILES,
of 18 East Dulwich Grove, in the County of Surrey, Secretary, 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 coverings or lining to be applied to pipes or vessels for
lessening conduction of heat to or from the material within them.

page_text: For this purpose, we coat with adhesive material such as silicate of soda solution,
a sheet of canvas or other fabric, and on the coated surface we lay at small intervals
apart parallel to each other loose ropes formed by giving a slight twist to bundles
of asbestos fibres, which may in some cases have other fibres mixed with them.
These loose ropes are caused by the silicate coating to adhere to the fabric
backing, the whole constituting a protective covering which can be wrapped round
pipes or vessels; or it may be a protective lining.
The rope form in which the fibres are laid and the small intervals between
them allow the covering to be readily wrapped around pipes even of small
diameter.
Instead of employing asbestos fibre, other fibres may be used in a similar way
also powders which are bad conductors of heat, such as ground cork, infusorial
earth, or the like, can be moulded with agglutinating material into bars of
triangular or trapezoidal section and cemented by their bases on to a fabric
backing.
In applying the covering to a pipe, cylinder or the like, it is wrapped round and
the meeting edges are connected by stitching or in any other known inanner.
A convenient mode of connecting them is to provide near each edge a row of
lacing hooks, eyelets or studs rivetted in the fabric in the usual way and then on
bringing the edges together to secure them by lacing with cord.
Fig. 1 of the accompanying drawings is a transverse section shewing, by way of
example, a pipe with a non-conducting covering according to this invention, Fig. 2
is a plan shewing part of the covering unfolded.
Fig. 3 shews a modification.
The covering consists of a backing A of suitable fabric on which are laid slightly
twisted bundles B of fibres which may be asbestos or other fibres or mixtures
of these.
These bundles are laid parallel to one another either transversely, or it might be
diagonally, and are held to the backing by the adhesive material, such as silicate of
soda with which the backing is served. The covering being wrapped round the
pipe may be secured thereon by lacing C through eyelets provided near the edges
of the backing, or these edges may be stitched or otherwise fastened together. As
shewn in Fig. 3 the non-conducting material consists of moulded bars. D of
trapezoidal section consisting of suitable pulverulent material such as cork dust
made up with agglutinating substance and cemented to the backing A.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we would have it understood
that we make no general claim to coverings or linings consisting of a backing of
fabric with segments of non-conducting material cemented thereto, but what we
claim is :-
1. A non-conducting cover or lining consisting of backing fabric on which are
cemented parallel lengths of loosely, twisted ropes of fibres, substantially as
described.
2. A cover or lining consisting of backing fabric on which are cemented parallel
bars of trapezoidal or such like section inade of pulverulent non-conducting material
made up with agglutinant, substantially as described.
