PROVISIONAL SPECIFICATION.
Improvements in Resistent Coverings for Battery Room Floors or
Surfaces, Laboratory Floors, and like uses.
We ROOKES EVELYN BELL CROMPTON of Mansion House Buildings, Queen Victoria
Street in the City of London, Electric Light Engineer, and BEN HOLMES JENKINSON
of the same place, Electric Light Engineer's Assistant, do hereby declare the nature
of this invention to be as follows:-
The object of the invention is to provide resistent surfaces especially applicable for
covering the floors and other parts of laboratories, battery rooms of electrical
installations and other places where the action of acids and other chemical bodies is to
be guarded against.
In carrying out the invention we utilize the resistent properties of natural asphaltum
or bitumen such as that obtained from the island of Trinidad, suitably refined, and
admixed with crushed or reduced slate or schistous bodies of like resistent properties
when subjected to the action of acids.
The bitumenous matter which is to form the cementitious agent is added to the
reduced slate whilst preferably both are in a heated condition as thereby the close
intimate admixture of the two is much facilitated.
The reduced slate may be added to the molten bitumen and continuously and
thoroughly stirred therein.
The heat employed may be from 212° or even more up to much higher temperatures
in certain cases, or for special uses.
In some instances the boiling is effected in closed vessels with more or less pressure
and with the aid of mechanical stirring and with or without the use of steam
distributed over the under surfaces of the mass to prevent coking on the bottom of
the boiler.
This composition of bitumen and slate is whilst hot spread over the surface to be
protected, such as on a bed of concrete or stone, a floor of wood, or metal, or a floor
of asbestos or other felt on wood, concrete, or other solid substance.
The bed being suitably prepared the composition is spread thereon to a uniform
thickness and levelled by the aid of heated tools in the case of floors and dusted with
finely reduced slate to prevent adhesion of the surface to passing bodies and to
produce a better surface."
The surface may be highly polished when suitably levelled.
The mode of procedure when forming acid resistent chambers, cells or vessels may
be substantially the same using pressure suitably applied to shape the matters.

Street in the City of London, Electric Light Engineer, and BEN HOLMES JENKINSON
of the same place, Electric Light Engineer's Assistant 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:-
The object of the invention is to provide resistent surfaces especially applicable for
covering the floors and other parts of laboratories, battery rooms of electrical

page_text: installations and other places where the action of acids and other chemical bodies is to
be guarded against.
In carrying out the invention.we utilize the resistent properties of natural asphaltum
or bitumen such as that obtained from the island of Trinadad, suitably refined, and
admixed with crushed or reduced slate or schistose bodies of like resistent properties
when subjected to the action of acids.
The bitumenous matter which is to form the cementitous agent is added to the
reduced slate whilst preferably both are in a heated condition as thereby the close
intimate admixture of the two is much facilitated.
The reduced slate may be added to the molten bitumen and continuously and
thoroughly stirred therein.
The heat employed may be from 212° or even more up to much higher temperatures
in certain cases, or for special uses.
In some instances the boiling is effected in closed vessels with more or less-pressure
and with the aid of mechanical stirring and with or without the use of steam:
distributed over the under surfaces of the mass to prevent coking on the bottom of
the boiler.
This composition of bitumen and slate is whilst hot spread over the surface to be
protected, such as on a bed of concrete or stone a floor of wood, or metal, or a floor
of asbestos or other felt on wood, concrete, or other solid substance.
The bed being suitably prepared the composition is spread thereon to a uniform
thickness and levelled by the aid of heated tools in the case of floors and dusted with
finely reduced slate to prevent adhesion of the surface to passing bodies and to produce
a better surface.
The surface may be highly-polished when suitably levelled.
The mode of procedure when forming acid resistent chambers, cells or vessels may
be substantially the same using pressure suitably applied to shape the matters.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1 In the manufacture of resistent coverings for battery room floors or surfaces,
lining of tanks or cells to contain acid, laboratory floors and like uses, the admixture
of natural asphaltum or bitumen with crushed or reduced slate or schistose bodies of
like resistent properties substantially in the manner and for the purpose hereinbefore
set forth.
2 As a new article of manufacture a resistent covering for battery room floors
or surfaces, laboratory floors and like uses compounded of natural asphaltum or
bitumen and crushed or reduced slate or schistose bodies of like resistent properties
prepared in manner substantially as herein before set forth.
