A New or Improved Composition for use as a Flooring and Roofing
Material, also applicable to other Purposes.
I, JOHN Ross, of 105, Bridge Road, Hammersmith, Gentleman, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention relates to a new or improved composition intended for use as a
flooring and roofing material, while it may also be employed for other purposes
such for instance as for forming. the wearing surface of roadways, pathways, and
the like, the object being to provide a comparatively cheap material capable of
being easily and conveniently applied without requiring the use of highly skilled
labour, while it is water-proof, practically fire-proof and extremely durable, more-
over with the use of this material expansion and contraction with variations of
temperature are reduced to a minimum.
In preparing this composition, one part of ground blue black clay is mixed with
3 parts of slack lime (kunkur if available), the whole being ground, this is then
sundried, preferably in the shape of balls two and a half inches in diameter and
burnt until of a brown appearance, this burning taking about 10 hours. These
balls are then ground and sifted until a powder of a very fine consistency is obtained
when it is mixed with fine sand in the proportions of 3 parts of the powder to
one part of sand, and this constitutes the first process in the manufacture of the
composition.
The second operation consists in melting a required quantity of pitch, constantly
stirring same, and to this is added an equal weight of the material resulting from
the first process of manufacture, the powder being gradually added until the whole
mass assumes a tenacious appearance.
In this state it is laid, preferably about half an inch thick, or of other suitable
thickness according to requirements, and in quantities preferably not covering an
area of more than 3 square feet at a time, and for flooring and the like it is
preferably laid on a previously prepared concrete bed of about 3 inches thick,
while for roofing purposes it need not be laid more than a quarter of an inch thick
and upon any suitable foundation or support for the substance.
Thus prepared and used the composition will consolidate within about 25 minutes
from the time of laying, while it may be broken up, re-melted and employed time
after time with or without the addition of fresh material.
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
I claim is:-
-
1. The new or improved composition composed of blue black clay, slacked lime,
sand and pitch, in or about the proportions herein stated, and prepared substantially
Las horain desavibed and for the purposes specified

also applicable to other purposes to which it is suitable, substantially as herein
described.
