PROVISIONAL SPECIFICATION.
A Fireproof Composition or Cement for Boilers, Flues, Furnaces.
GEORGE CROSLAND TAYLOR Ravenscar Helsby near Warrington Electrical
Engineer. I do hereby declare the nature of this invention to be as follows:-
A fireproof composition or cement is often required either to cover boiler plates,
or boiler flue tops, or to set bricks of furnaces, or to reline same therewith. I find
that a composition or cement, composed of a mixture of clean sharp sand, asbestos
wool, or slag wool fibres, mixed with a solution of water and silicate of soda pro-
duces a fireproof, & heat resisting, or heat insulating compound, or non conductor
of heat, this is soft when placed in position, but hardens when heated, or dried,
more or less, according to the different quantities of each of the above named sub-
stances put into the composition or cement thereby producing a durable composition
or cement, this can be loosened, & the same replaced in position and rehardened,
by addition of water, with or without a slight addition of silicate of soda.
Dated this 14th day of June 1892.

COMPLETE SPECIFICATION.
A Fireproof Composition or Cement for Boilers, Flues, Furnaces.
GEORGE CROSLAND TAYLOR, Ravenscar, Helsby, near Warrington, Electrical
Engineer. I 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 :-
A fireproof composition, or cement, for boilers, flues, furnaces is often required
either to cover boiler plates, or shells, or boiler flue tops, or to set bricks of furnaces,
or to reline same therewith.
I find that a composition, or cement, composed of a mixture of three parts by
volume of clean sharp sand, preferably free from oxide of iron, and chloride of
sodium, with 2 parts by volume of asbestos fibres, preferably rather finely divided,
mixed with two parts by volume thereabouts, of a solution consisting of silicate of
soda, and water, (viz. about ten per cent. of concentrated syrupy commercial silicate
of soda, to 90 per cent. of water, both measured by volume, hot or cold) produces
fireproof, and heat resisting, or heat insulating, compound or cement, or non-con-
ductor of heat; this is applied soft similar to the consistency of stiff lime mortar,
when placed in position, but hardens when heated, & water more or less evaporated
away; producing a durable composition or cement.
a
The hardness, fireproof resistance, & heat insulation, or non-conductivity of
heat qualities, depend on the different quantities, & qualities, & strengths, of the
aforesaid substances mixed into the composition, or cement. The silicate of soda is
for the purpose of holding the sand, & asbestos, together when dried, the asbestos
for heat-insulation purposes, and the sand for beat resisting purposes; the amounts
of these various substances incorporated in the composition, or cement, can be
altered accordingly, but for practical purposes the quantities stated are to be
preferred.
This composition or cement can be made soft again by addition of hot, or cold
water, containing or not a slight amount added, of silicate of soda; on being
replaced in position will again set hard on heat being applied, thereby being of use
once, & over again as may be required.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, & in what manner the same is to be performed, I declare that what I
claim is:
I. A. composition, or cement, composed of sand, asbestos, and silicate of soda, and
water, as described, and of varied proportions as described, & for the purposes
described.
II. A combination of this composition, or cement, as described, but with, or
without the addition of the asbestos, as applied to, or in conjunction with boiler flue
covers, constructed as described in my Specification, No. 6594, April 6th 1892.
Improvements in flue covers, as applied to steam boilers.
Dated this Seventh day of December 1892.
