PROVISIONAL SPECIFICATION.
Improvement in the Manufacture of Cement Mortar.
MILES WILLIAMS 86 Queen's Road Bootle Liverpool Manufacturing Chemist
do hereby declare the nature of this invention to be as follows:-
I take furnace or other ashes, cinders, slag coke stone brickbats or similar
substances or mixtures of these in a dry state and then grind disintegrate or
pulverise them into powder by a roller or other grinding mill. I then thoroughly
intermix the ground ashes before or after grinding with a proportion of prepared
clay, clayey earth or alumina and lime slaked with water to a dry powder but
containing no sodium chloride, thus differing materially thereby from the slaked
lime and mortar as described in my Patents Nos. 7255 and 119488.
The proportions of the materials may be varied to form either air-drying or
hydraulic cement mortar and so producing a dry cement mortar which in this state
resembles ordinary cement but unlike ordinary cement it possesses the important
quality whilst dry of not becoming dead, and retains its vital power for any length
of time. When required for use it is simply wetted with water like ordinary
cement and made plastic. It does not set or become hard so quick as ordinary cement,
but it sets quicker and much harder and is a faster binding material than wet
ground or sand and lime mortars.

MILES WILLIAMS 86 Queen's Road Bootle Liverpool Manufacturing Chemist
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 :-
I hereby declare the nature of my invention for improvement in the manufacture
of cement mortar to be as follows:-I take furnace or other ashes or cinders, slag,
coke, stone, brickbats or similar substances or mixtures of them in a dry state and
then grind, disintegrate or pulverise them into powder by a roller or grinding
mill. I then thoroughly intermix the ground ashes-before or after grinding with
a proportion of prepared clay, clayey earth or alumina and lime slaked with water
to a dry powder, but containing no sodium chloride, thus differing materially thereby
from the slaked lime and mortar as described in my Patents No. 7255 and 1194884.
The proportions of the materials may be varied to form either air-drying or
hydraulic cement mortar. For ordinary cement mortar, I take about eight parts
furnace ashes, slag, or coke or similar substance & four parts hydrate of lime and one
part clay, and so producing a dry cement mortar which in this dry powdered state
resembles ordinary cement but unlike ordinary cement it possesses the important
quality whilst dry of not becoming dead and retains its vital power for any length
of time. When required for use it is simply wetted with water like ordinary
cement and made plastic. It does not set so quickly as ordinary cement but it sets
quicker and is a much harder and faster binding material than wet ground or sand
& lime mortars.

page_text: 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 :-
1st. A dry cement mortar.
2nd. A mortar in a dry fine powder having cement-like appearance and
properties.
3rd. Air-drying or hydraulic cement mortar.
4th. An hydrate of lime in a dry powder for mortar plastering and other
purposes.
