PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Tobacco Pipes and other
articles.
I, ROBERT TANNER, of 448 Bolton Road, Small Heath, Birmingham, Pipe
Manufacturer do hereby declare the nature of this invention to be as follows:-
:-
For this purpose I mix with vegetable fibres such as hemp, jute, linen flax,
cotton and also wood fibre, a thick varnish such as shellac in solution and mould
the same in a required shape and then place the article to dry in a cold room and
when ready for use place them in a die subjected to a slight pressure-after that
process I in the case of pipes give them a coating of asbestos dust mixed with the
same varnish and then again place them to dry in a cold room and when ready for
use again place them in a die subjected to a much heavier pressure then place them
in an oven which is about 250 degrees for about 4 hours till the whole substance is
vulcanised then place them in a die subjected to a very heavy pressure and when
taken out the article is ready for polishing.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Tobacco Pipes and other
articles.
I, ROBERT TANNER, of 448 Bolton Road, Small Heath, Birmingham, Pipe
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 :-
For this purpose I mix with vegetable fibres such as hemp jute linen flax cotton
also wood fibre a thick varnish such as shellac in solution and mould the same into
a required size and shape and then place the articles to dry in a cold room for
about 4 days and when ready for use place them in a die subjected to a slight
pressure after that process in the case of pipes and other articles which go
through the process of being japanned and polished, I give each article a thin
coating of asbestos dust mixed with the same varnish to form a smooth and hard
surface for japanning and to protect the vegetable fibres from the heat which is
required for japanning after the article has been coated with the asbestos dust
mixed with the same varnish as mentioned above they are placed to dry in a cold
room for about 5 or 6 days and when ready for use again place them in a die
subjected to a much heavier pressure then each article is placed in an oven which
is about 250 degrees F. for about 4 hours nntil the whole substance is vulcanised
then place them in a die subjected to a very heavy pressure and when taken out of
the die the article is ready for japanning and polishing.
When I make articles entirely of wood fibre I take the dry fibre and press it
into a die or mould to the required shape and when taken out I soak it with the
solution of shellac varnish and then place it to dry in a cold room for about 4 or
5 days after that I place it in an oven at a low degree of heat say about
60 degrees F. for about eight hours then I place it in a die subjected to a slight
pressure when taken out of the die I place it into an oven again at a higher degree
of heat to about 120 degrees F. for about 4 hours and when taken out I place them
in a die subjected to a very heavy pressure and allow them to remain under
pressure for a short time so as to cause the fibres to unite and become solid.

page_text: The quantity of varnish required depends upon the nature of the article.
For pipes every fibre should be well coated whereas in some cases for other
articles the varnish need only be applied to the surface after it has been roughly
moulded.
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 :-
The manufacture of tobacco pipes and other articles from fibrous materials
