PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Bricks, Tiles, Blocks, Roofing
Materials, and other such like Articles and Compositions.
I, JOHN DAVIES, of 26 Barnsbury Road, Islington, in the County of London,
Quarry Proprietor, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the manufacture of bricks, tiles, and other such like
articles such as roofing materials, from slate debris or slate refuse, in combination
with silica and asphalt, and for this purpose the slate is ground up into a fine state
by edge runners, disintegrators, or by other machinery suitable for the purpose,
then mixed with the silica and asphalt, and the material thus combined is subsequently
manufactured into bricks, tiles, roofing materials, or other forms, by any of the
means or machinery capable of making the combined material into the required
articles. Lime in some instances should be added.
The approximate proportions of the materials are, for fire bricks, say equal parts
of powdered slate debris, and silica. For roadway's paving, by a combination of
say slate debris and asphalt.
Foot-paths are according to my invention made by a combination (equal propor-
tions) of slate debris and "commercial" asphalt.
A combination of asphalt and slate debris in equal proportions will render roofings
impervious to wet and damp.
Tiles and bricks are submitted to the ordinary pressure used in the manufacture
of such articles.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Bricks, Tiles, Blocks, Roofing
Materials, and other such like Articles and Compositions.
I, JOHN DAVIES, of 26 Barnsbury Road, Islington, in the County of London,
Quarry Proprietor, 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 :-
My invention relates to the manufacture of bricks, tiles, and other such like
articles, such as roofing materials for example, from slate debris, or slate refuse in
combination with silica and also asphalt, (except as hereafter mentioned) and for
this purpose the slate is ground up into a fine state by edge runners, disintegrators,
or by other machinery suitable for the purpose, and is then mixed with the silica
and asphalt, or in the case of fire bricks, and such like articles, the asphalt may be
dispensed with as hereafter mentioned.
The materials thus combined are subsequently manufactured into bricks, tiles,
roofing materials, or other forms by any of the means or machinery suitable for, or
capable of, making the combined materials into the required articles. Lime in some
instances should or may be added.
The approximate proportions of the materials are, for fire bricks, say, equal parts
of powdered slate debris and silica. For roadways paving by a combination of,

page_text: say, slate debris and asphalt, with the addition of silica in such proportions as
will suit the particular circumstances.
Foot paths are, according to my invention, made by a combination (equal propor-
tions) of slate debris and "commercial" asphalt, with the addition of silica as
previously stated.
A combination of asphalt and slate debris in equal proportions with the addition
of silica as required will render roofings impervious to wet and damp. Tiles and
bricks are submitted to the ordinary pressure used in the manufacture of such
articles..
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with slate debris or slate refuse previously ground to a
suitable degree of fineness, of suitable proportionate quantities of silica and asphalte,
all substantially as and for the purposes herein set forth.
2. In the manufacture of fire bricks and such like articles, the combination with
slate debris or slate refuse previously ground to a suitable degree of fineness, of
suitable proportionate quantities of silica, all substantially as herein set forth.
3. The improved compositions or materials as described for the manufacture of
bricks, tiles, blocks, roofing materials and such like articles and compositions,
composed of slate debris or refuse, silica and asphalt, with or without the addition
of lime as required, all substantially as and for the purposes herein set forth.
