Improvements in the Manufacture of Tobacco-pipes.
I, CONRAD MATHIEU BRIX, of 6 Gumperdorferstrasse, Vienna VI, in the
Empire of Austria, Manufacturer, do hereby declare the nature of this invention
to be as follows :-
My invention relates to improvements in the manufacture of tobacco-pipes.
According to my said invention I pulverize pieces of meerschaum and pour spirit
of a high degree of concentration (for instance 90 per cent. spirit) thereon, while
continually stirring, until a pasty mass is produced with which fibrous asbestos and
any desired binding agent, such as water-glass, paste, glue, isinglass, gum-tragacanth,
cement, or the like, are mixed until the mass assumes a pasty consistency.
The proportions of the materials mixed together (meerschaum, asbestos) are
optional and depend chiefly on the desired hardness of the tobacco-pipes to be
obtained.
When the mass has been well kneaded it may be moulded in the customary
manner to form pipes.
After their removal from the moulds the pipes are allowed to dry slowly in the
open air, if necessary from a week to a fortnight, without using higher temperatures,
whereupon they are ground, polished and coated with a refractory varnish.
Dated this 23rd day of October 1893.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Tobacco-pipes.
I, CONRAD MATHIEU BRIX, of 6 Gumperdorferstrasse, Vienna VI, in the
Empire of Austria, Manufacturer, 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 improvements in the manufacture of tobacco-pipes.
According to my said invention 1 pulverize pieces of meerschaum and pour
rectified spirits of wine of a high degree of concentration (for instance 90 per cent.
spirit) thereon, while continually stirring, until a pasty mass is produced. I then
mix fibrous asbestos together with any desired binding agent such as water-glass,
paste, glue, isinglass, gum-tragacanth, cement or the like with the mass until the
same assumes a pasty consistency.

page_text: The proportions of the materials mixed together, that is to say, of meerschaum
and asbestos may be varied considerably and depend chiefly on the desired hardness
of the tobacco-pipes to be obtained.
For example I find that a mixture of ingredients in the following proportions
gives satisfactory results ;-
Spirits of wine
Asbestos fibre
Water-glass
The following proportions also give a very good result;
Meerschaum
Spirits of wine
Asbestos fibre
Paste

-
0.25 litre
-
0.5 kilogramme
-
0.5 kilogramme.
0.1 kilogramme
-
0.25 kilogramme
-
0.5 kilogramme
-
1.0 kilogramme.
These proportions are given merely as examples and I do not limit myself to the
same.
When the mass has been well kneaded it is moulded in the customary manner to
form pipes.
After removal from the moulds the pipes are allowed to dry slowly in the open
air, for a week or a fortnight if necessary, without using a high temperature.
After drying the pipes are ground, polished and if desired coated with a refractory
varnish.
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 I am
aware of the Specification of Jackson's Patent No. 11976/85, and I make no claim
to anything described and claimed therein, but what I claim is :-
1. The method of making tobacco-pipes by treating pulverized meerschaum with
spirit and mixing the resulting mass with asbestos and a suitable binding agent, and
then moulding or otherwise forming the same into a tobacco pipe substantially as
.described.
2. A. tobacco-pipe manufactured of a mixture of meerschaum and asbestos.
