PROVISIONAL SPECIFICATION.
Improvements in Coverings for Preventing the Radiation or
Transmission of Heat.
1, JAMES CROFT SEWELL of 24 River Street, Shiffnall Street, Bolton, Lanca-
shire, Composition Manufacturer, do hereby declare the nature of this invention to
be as follows, that is to say :-
It relates to improvements whereby animal and vegetable fibres on being made
into sheets, may be used as coverings for hot water pipes, hot air pipes, steam
boilers, steam pipes and the like and consists of the application thereto of means
for preventing the burning er charring of the surfaces of the various materials when
in contact with the heated surfaces to which they are applied. Thi; I propose to
do in the following manner when the sheets of animal and vegetable fibres are made
into the forms or shapes ready for being applied.
After soaking or saturating these sheets of fibres in a solution of alum and water,
I take them and firstly cover the inside surfaces (or those surfaces which are for
contact with the heated pipes or the like) with a coating of silicate of soda.
Over this silicate of soda coating I place another coating of fine clay (of the
class usually employed for this purpose) and then allow the whole to dry prior to
putting it into use, or the sheets thus prepared may be at once applied to the
heated surfaces.
When the heated surfaces are not of very high temperature, I omit the treat-
ment of the sheets by the alum solution, or, if, I use this, then I omit one or other
of the coatings, that is to say of the silicate of soda or of the fine clay.

Improvements in Coverings for Preventing the Radiation or
Transmission of Heat.
1, JAMES CROFT SEWELL of 24 River Street, Shiffmall Street, Bolton, Lauca-
shire, Composition Manufacturer, 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, that is to say :-
It relates to improvements whereby animal and vegetable fibres on being made
into sheets, may be used as coverings for hot water pipes, hot air pipes, steam
boilers, steam pipes and the like, and consists of the application thereto of means
for preventing the burning or charring of the surfaces of the various materials
when in contact with the heated surfaces to which they are applied.
This I propose to do in the following manner when the sheets of animal and
vegetable fibres have been already made into the shapes or forms to fit the parts to
which they have to be applied :-
After soaking or saturating these formed sheets of fibres in a solution of alum
and water, I take them and firstly cover the inside surfaces (or those surfaces

page_text: which are for contact with the heated pipes or the like) with a coating of silicate
of soda.
Over this silicate of soda coating I place another coating of fine clay (of the
class usually employed for this purpose and which is well known) and then allow
the whole to dry prior to putting it into use, or the sheets thus prepared may be at
once applied to the hented surfaces.
When the heated surfaces are not of very high temperature, I omit the treat-
ment of the sheets by the alum solution, or, if I use this, then I may omit the
coating of silicate of soda.
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 :-
1. The method of and means for preparing coverings for preventing the
radiation or transmission of heat substantially as herein specified.
2. In the production of coverings for preventing the radiation or transmission
of heat, the employment of sheets of animal or vegetable fibre, a solution of alum
and water, silicate of soda and fine clay in combination substantially as herein
specified.
3. In the production of coverings for the purpose described the employment of
sheets of aniinal or vegetable fibre, a solution of alum and water and fine ciay in
combination substantially as herein specified.
4. In the production of coverings for the purpose described the employment of
sheets of animal or vegetable fibre, silicate of soda and fine clay substantially as
herein set forth.
