Improvements in Artificial Stone.
We, ASPINALL BROOKE, of Hipperholme, NEWTON BROOKE, of Lightcliffe, and
WILLIE BROOKE, of Lightcliffe, all of the Firm of Joseph Brooke and Sons, of
Hipperholme, Stone Merchants, do hereby declare the nature of this invention
to be as follows:-
The object of our invention is to produce an artificial stone for building and
paving material, such as, paving slabs, copings, blocks, heads, sills, sinks, chan-
nels and the like either plain, decorative or both in surface or in substance,
from the slurry or waste refuse from stone sawing and scouring or polishing
plant, also from the waste products of Lancashire sandstone, ashlar and flagrock.
The said slurry or waste refuse from stone sawing and scouring or polishing
plant is mixed with suitable proportions of Portland cement or other suitable
cement or binding material and placed in porous or other moulds of suitable
size and shape subjected to great pressure and formed into the required blocks.
The waste products of Lancashire stone such as sandstone, ashlar and flag-
rock are ground un very fine and mixed with suitable quantities of Portland
cement and water and put into porous or other moulds of the shape required as
before described and form an artificial stone with all the qualities of the best
natural stone.
Or the slurry or waste refuse from the sawing and scouring or polishing plant
may be mixed with any proportion of the finely ground waste products of Lan-
cashire stone or other finely ground waste stone, then mixed with a suitable
quantity of cement and water moulded and pressed as before described.
Dated this 29th day of March 1898.

WILLIE BROOKE, of Lightcliffe, all of the Firm of Joseph Brooke and Sons, of

and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-

from the slurry or waste refuse from stone sawing and scouring or polishing
plant, also from the waste products of Lancashire flagrock, ashlar, and sand-
stone.
The natural stone chosen for paving is of the sandstone order, on account of
its nonslipping properties, its great fault being, that it laminates more or less
readily under the influence of the weather, it is also very expensive.
From the above waste products we produce an artificial stone which has all
the advantages of the best natural stone, without the disadvantage of laminating.
The said slurry or waste refuse from stone sawing and scouring or polishing
plant, is mixed with suitable proportions of Portland cement, or other suitable
cement, or binding material and water, and is placed in porous or other moulds
of suitable size and shape, subjected to great pressure, and formed into the
required blocks.
The waste products of Lancashire stone, such as sandstone, ashlar, and flag-
rock, are ground up very fine, and mixed with suitable quantities of Portland
or other suitable cement and water, and put into porous or other moulds of the
shape required as before described, and form an artificial stone (with all 'the
qualities of the best natural stone), but which does not laminate.
Or the slurry or waste refuse from the sawing and scouring or polishing plant
may be mixed with any proportion of the finely ground waste products of Lan-
cashire stone, or other finely ground waste stone, then mixed with a suitable
quantity of cement and water, moulded and pressed as before described.
The fine grinding of the waste products is absolutely necessary,
'
It is understood that in all cases the quantity of cement may be varied from
half and half, to one part of cement, to three or four of the waste products,
according to the quality of such waste products.
By the above described means, we produce an artificial non-slipping paving,
also building stones, having all the good properties of the best natural stone,
at about one half the cost
Having now particular described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. The production of artificial stone of any form or shape required, from the
waste products, such as herein described.
2. The use, in the production of artificial stone, of any form or shape required,
of the waste products herein described.
