Improved Fibrous Asphalt Composition for Rendering Concrete Roofs,
Railway Arches, Walls, and other Structures Waterproof and
Dampproof, and in the Method of Applying such Composition.
JAMES CLIFFE, of 55 Thurlow Street, Eccles New Road, Salford, in the County of
Lancaster Asphalt and Concrete Contractor, do hereby declare the nature of this
invention to be as follows:
To render concrete roofs, Railway Arches, Walls and other Structures waterproof
and damp proof,' by the application thereto of the following Fibrous Asphalt Composi-
tion, in the manner herein-after described.
The composition is formed by the admixture in about equal parts of the following
ingredients namely Liminer rock asphalt bitumen, sand, limestone, pitch, creosote
oil, Varnish, tar, and cow hair and cotton waste'; and inserting in same sacking cloth.
The surface to be rendered waterproof is first thoroughly dried by the application
of hot sand and dry cloths; then the above composition is reduced to a pulpy substance
by heat, and a layer of the same, about three-quarters of an inch thick, is floated on
the top of the roof or arch, and a covering of sacking cloth secured to this layer By
pressure with a roller whilst the composition is warm; a second layer of the compo-
sition is then floated, about one quarter inch thick, and a second covering of sacking
cloth laid at an angle of forty five degrees to the first covering and secured as before
described; a third layer of the composition about one-quarter inch thick is then floated
and a third covering of sacking cloth laid transversely to the second covering and
secured as before, and finish off with a layer of the composition about a half inch
thick.

JAMES CLIFFE of 55 Thurlow Street Eccles New Road, Salford, in the county of
Lancaster Asphalt & Concrete Contractor 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 :-
To render concrete roofs, railway arches walls & other structures waterproof and
damp proof by the application thereto of the following Fibrous asphalt composition
in the manner hereinafter described.
The composition is formed by the admixture in about equal parts of the following
ingredients namely; Limmer rock asphalt, Bitumen Sand, Limestone, Pitch, creosote
oil, varnish, Tar, Cowhair cotton & Fibre waste and inserting in same sacking
cloth.
The surface to be rendered waterproof is first thoroughly dried by the application
of hot sand and dry cloths; then the above composition is reduced to a pulpy substance
by heat and a layer of the same about three quarters of an inch thick is floated
on the top of the roof or arch and a covering of sacking cloth secured to this layer by
pressure with a roller whilst the composition is warm; a second layer of the composi-
tion is then floated about a quarter of an inch thick and a second covering of sacking
cloth laid at an angle of forty five degrees to the first covering and secured as before
described; a third layer of the composition is next floated about one quarter inch thick
and a third covering of sacking cloth laid transversely to the second covering and
secured as before and finish off with a layer of the composition about a half inch thick.
Having now described the nature and object of my said Invention together with the
manner the same is to be or may be performed or carried into practical effect, I wish
it to be understood that I claim as my Invention the manufacture and use or applica-
tion of, the Fibrous Asphalt Composition substantially in the manner and for the
purposes above particularly set forth and described.
In witness whereof, 1, the said James Cliffe, have hereunto set my hand and seal
this Twenty sixth day of October in the year of our Lord, One thousand
eight hundred and eighty eight.
