PROVISIONAL SPECIFICATION.
An Improved Manufacture of Waterproof, Fire, and Weather
Resisting Material for Roof Coverings.
1, RUDOLF WESTPHALEN FURSTENBERG, of Vienna, Austria, Reichsgraf, do
hereby declare the nature of this invention to be as follows:-
:-
This invention relates to an improved manufacture of waterproof fire and weather
resisting material for roof coverings, which is composed of a mixture of asbestos-
fibre, asbestos-card-waste, zinc oxide, curd soap, alum, carbonate of soda, sugar of lead,
and zinc chloride, this mixture being formed into sheets or slabs by the ordinary
process for making carton.
The said compound is formed by intimately mixing the above mentioned substances
about in the following proportions:
50 Kilogr. asbestos-fibre, 10 Kilogr. ground asbestos-card-waste, and 10 Kilogr.
zinc oxide are introduced under stirring into a rag-engine containing about from 300
to 350 litres of water, after which are added under continued stirring about 7 litres
of a zinc chloride solution of from 50 to 60° B. About an hour afterwards,
about 10 litres of a solution of about 1 Kilogr. of curd soap in about 10 litres of
boiling water are added, and immediately afterwards are added about 21 litres of a
solution consisting of 3 Kilogr. of alum dissolved in 21 litres water, 300 grammes of
carbonate of soda dissolved in 2 litres of water, and 800 grammes of sugar of lead
dissolved in 2 litres of water.
After the whole of the above ingredients have been incorporated to a homogeneous
mass, this is introduced into a stirring vat and is then subjected to the usual process
for the manufacture of carton, for the production of sheets, slabs, or rolls applicable
as coverings for roofs.

as coverings for roofs.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
-claim is :-
1. The production of material for roof coverings by mixing asbestos fibre with
asbestos paper waste, zinc oxide, zinc chloride, curd soap, alum, carbonate of soda, and
sugar of lead, substantially as herein described.
2. An improved manufacture of fire and waterproof coverings for roofs consisting
of a compound of the substances referred to in the first claim treated by the ordinary
carton making process for conversion into sheets or slabs.
