PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Cement or Artificial Stone.
I FRANK TURNER of 3 Castle Hill, Carnarvon, Wales, Quarry Agent do
hereby declare the nature of this invention to be as follows:-
This invention relates to a novel compound composed of powdered limestone and
powdered waste slate and powdered stone or stone chippings in suitable proportions
intimately mixed with fresh or salt water. The slip or slurry, if for cement, is
spread upon layers of coke in a kiln to the desired height for the water or moisture
to be absorbed by the coke and be rapidly dried thereby. The coke becomes
slightly impregnated with limestone which renders it specially adapted for fuel in
the burning operation and making a better cement than when the slip is thoroughly
dried before being placed in the kiln as at present.
The stone admixture may when in the slurry state be poured into moulds for
shaping purposes and be pressed to solidify it into slabs for paving and like purposes
or be ground and polished for decorative work.

I, FRANK TURNER, of 3 Castle Hill, Carnarvon, Wales, Quarry Agent, 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 a novel compound composed of powdered limestone,
powdered waste slate, and powdered stone, or stone chippings in about equal
proportions intimately mixed with fresh or salt water. The slip or slurry, if for
cement, is spread upon layers of coke in a kiln to the desired height for the water
or moisture to be absorbed by the coke and be rapidly dried thereby. The coke
becomes slightly impregnated with limestone which renders it specially adapted for
fuel in the burning operation, and for making a better cement than when the slip is
thoroughly dried before being placed in the kiln, as at present.
The stone admixture may when in the slurry state be poured into moulds for
shaping purposes, and be pressed to solidify it into slabs for paving and like purposes,
or be ground and polished for decorative work.
Having now particularly described and ascertained the nature of this inveu-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improvement in the manufacture of cement, viz.: compounding powdered

page_text: limestone and waste slate dust or stone chippings with water to form a slurry and
spreading said slurry upon coke in a kiln for absorption of the moisture and rapid
drying within the kiln before burning, as and for the purposes set forth.
2. The improvement herein before described viz.: moulding slurry composed of
material referred to in the first claiming clause hereof for the production of blocks
or slabs, as and for the purposes set forth.
