GABRIEL FRANCIS JEFFERY of 44A Park Square Leeds Colliery Furnisher do
hereby declare the nature of this invention to be as follows:-
"
I apply to both sides of a certain article, woven from Jute, a dressing known as
filling," and upon what is to be regarded as the outer surface of the cloth, I further
apply a composition of paint and varnish in variable colours as required, which com-
position renders the cloth water-tight.

page_text: I. GABRIEL FRANCIS JEFFERY, of 44A Park Square, Leeds, in the County of York,
Colliery Furnisher, 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 :-
This invention relates to an improved covering for roofs and has for its object to
provide a woven material which is water proof and which will withstand the action of
the weather.
In roof coverings heretofore proposed felted material has been commonly used,
but this is liable to the inconvenience that when once laid and after short
exposure to the weather it is difficult to remove. intact so as to be equally serviceable
in other places.
Now the object of my invention is to obviate this inconvenience which I do in the
following manner.
I apply to both sides of a certain article, woven from jute, a dressing known as
"filling," and upon what is to be employed as the outer surface of the cloth, I further
apply a composition of paint and varnished in variable colours as required, which
composition renders the cloth water-tight.
።
To carry this invention into practice I employ by preference a fabric or material
woven from Jute or other like raw material and first treat both sides of the said
material with a "composition or filling composed of drying oil and white lead,
or of drying oil and chalk, or of drying oil and both white lead and chalk.
suitable coloring or staining matter may be added to the "filling if thought
desirable.

Any
When this "filling" is thoroughly set and dry I apply to one surface only of the
material so prepared or :: filled (and which surface is to be used as its outer surface)
a second coating or "dressing" of the same or a similar "composition" or filling
as was used in the first instance and the "composition or filling" used in this
second coating or dressing may be coloured or stained by any suitable colouring or
staining materials whether the same or different from the colours or stains (if any)
used in the first treatment or "filling."
When this second coating or dressing is thoroughly set and dry I apply one or
more coats of varnish to the outer surface of the material, which varnish may be if
thought advisable, impregnated with a suitable colouring or staining material.

page_text: Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, I declare that what I claim is :-
My improved covering for roofs made from woven material such as referred to
in the manner above described.
