PROVISIONAL SPECIFICATION.
Improvements in the Construction of Heat Non-conducting
Material.
I, JAMES CROFT SEWELL of the Firm of Sewell and Company of 24 River
Street, Shiffball Street, Bolton in the County of Lancaster, Composition
Manufacturers, do hereby declare the nature of my said invention to be as
follows:-
This invention relates to improvements in the construction of heat non-conducting
material for covering hot and cold water pipes, steam boilers, steam pipes, hot air
pipes, ice houses, refrigerators, gas stoves, chemical apparatus, and the like, and
consists in means for preventing the burning of the outer cover to which silicate
cotton or slag wool or asbestos fibre is attached, thereby prolonging the life of the
covering and enhancing the value of the same. Hitherto silicate cotton or slag
wool, or asbestos fibre, has been secured in sections or otherwise to an outer lining
or casing of cloth made from hemp or other suitable fibrous substances, which is
speedily destroyed by the excessive heat to which the covering is subjected when
employed for covering heated surfaces. To overcome this defect and increase the
value of the covering I dispense with the said textile outer covering and substitute
therefor a metallic one in the form of woven wire or netting of any suitable
thickness that will allow of wrapping or otherwise. The said outer covering may
be constructed of any wire gauge and meshes according to the purpose for which it
is intended. The silicate cloth or slag wool or asbestos fibre may be woven thereto
or stitched with wire in any convenient manner.
Dated the 26th December 1893.

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 :-
In combination with silicate cotton or slag wool or asbestos fibre employed as a
heat non-conducting material for covering hot and cold water pipes, steam boilers,
steam pipes, hot air pipes, ice houses, refrigerators, gas stoves, chemical apparatus,
and the like, the use of woven wire or netting of any suitable thickness, wire gauge
and meshes that will allow of wrapping or otherwise according to the purpose for
which it is intended, the said silicate cotton or slag wool or asbestos fibre being
woven thereto, by power or hand, with wire in any convenient manner, substantially
as described.
