PROVISIONAL SPECIFICATION.
The Manufacture of Improved Materials for Roofing and other
Purposes, and of a Composition therefor.
I, ALFRED NAPIER FORD of 22, Gloucester Crescent, Regents Park, in the county of
London, Gentleman, do hereby declare the nature of this invention to be as
follows:-
This invention relates partly to improvements on my former Patent No. 17442 of
1887.
In practice I have found that the composition when manufactured according to
the Specification of my said former patent dried more quickly than was desirable
to ensure toughness and flexibility and that under the effect of heat it was liable
to become sticky during and after the process of application to the material. to be
coated.
The main object of my present improvements is to remedy the above named
defects, and for this purpose I add to the composition when in a fused state petroleum
oil in the proportion of about one gallon of petroleum oil to every twelve gallons of
the fused composition.
My invention also relates to the manufacture of improved materials for roofs for
buildings and erections, covers for vans, railway and other carriages, for building
sheds, for covering damp walls and floors, and as a substitute for leather for splash
boards, loin covers, driving belts, boxes, trunks and travelling bags, chairs, cushions,
tarpaulins and for waterproof material generally, also for pipes for conveying water
and other purposes.
In manufacturing an improved material suitable for roofing and cognate purposes I
take wire netting of a suitable mesh and a thin fabric such as canvas and pass them
through a pair of rollers, my improved composition in a heated liquid state being fed
onto the surface of the wire netting as it passes between the rollers.
When manufacturing tarpaulin and similar material, I employ canvas or like fabric
without wire netting and pass it through a trough filled with the melted composition
and having a revolving roller under which the material passes and it is then led
through rollers as above stated.

manner the same is to be performed to be particularly described and ascertained in
and by the following statement:-
This invention relates partly to improvements on my former Patent No. 17442 of

In practice I have found that the composition when manufactured according to
the Specification of my said former patent dried more quickly than was desirable
to ensure toughness and flexibility and that under the effect of heat it was liable
to become sticky during and after the process of application to the material to be
coated.

page_text: The main object of my present improvements is to remedy the above named defects,
and for this purpose I add to the composition (described in the Specification of my

sheds, for covering damp walls and floors and as a substitute for leather for splash
boards, loin covers, driving belts, boxes trunks and travelling bags, chairs, cushions,
tarpaulins and for waterproof material generally, also for pipes for conveying water
and other purposes.
In manufacturing an improved material suitable for roofing and cognate purposes,
I take wire netting of a suitable mesh, and a thin fibrous or textile fabric such as
canvas and pass them through a pair of rollers, my improved composition in a heated
liquid state being fed onto the surface of the wire netting as it passes between the
rollers.
When manufacturing tarpaulin and similar material I employ canvas or like fabric
without wire netting and pass it through a trough filled with the melted composition
and having a revolving roller under which the material passes and it is then led
through rollers as above stated.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what 1
claim is :-
(1) The manufacture and use of a composition tormed by the admixture of stearine-
pitch, oil soap, and petroleum oil in about the proportions and for the purposes above
set forth.
(2) The manufacture of materials for the purposes stated, by coating wire netting
and a suitable fibric or textile fabric, or fabric alone with the above named com-
position substantially as described.
