PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Tobacco Pipes.
I, HENRY RUDGE of 22 Sutton Road, Peasley Cross, St. Helens in the County
of Lancaster, Analytical Chemist, do hereby declare the nature of this invention to
be as follows:-
This invention has for its object the manufacture of tobacco pipes, whereby the
nicotine can be thoroughly absorbed into the material of the pipe, and the part so
absorbed thrown away and a similar part substituted very cheaply.
In place of forming the pipe of briar-wood or other like material, I form it of
unsized pulp similar to blotting paper, in fact of the same pulp that blotting paper
is made from, but instead of forming it in sheets I prefer to stamp the pipe out
direct from the pulp in order to prevent the burning tobacco from setting fire to
the paper pulp. The actual bowl consists of a thimble of porous carthenware
placed in the paper pulp bowl. The mouth-piece is of the usual description and is
fixed to the pipe by means of a sliding or screwed ferrule. By withdrawing the
ferrule, the mouth-piece can be withdrawn from the pipe and a fresh absorbent pipe
substituted. The bowl can also be taken out of the old pipe and added to the new
one, or as these bowls can be made extremely cheaply, it can be thrown away, if
desired, with the absorbent part of the pipe. The paper pulp can be dyed or
coloured to any desirable shade. I prefer, however, not to dye the pulp but to
colour the pipe after it is made on the outside only, as I have found that in such
case the pipe is more absorbent and there is no chance of any decomposition of the
colouring matter and causing of a disagreeable taste or poisonous effect.
This invention not merely includes making the pipe itself of this absorbent
material, but also forming an arrangement for lining pipes with this absorbent
material in such manner that the lining can be discarded and a fresh lining placed
in the pipe at a moment's notice.

COMPLETE SPECIFICATION.
Improvements in or appertaining to Tobacco Pipes.
I, HENRY RUDGE of 22, Sutton Road, Peasley Cross, St. Helens in the County
of Lancaster, Analytical 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.
This invention has for its object the manufacture of tobacco pipes, whereby the
nicotine can be thoroughly absorbed into the material of the pipe and the part so
absorbed thrown away and a similar part substituted very cheaply.
In place of forming the pipe of briar-wood or other material, I form it of unsized
wood or paper pulp, or the like, or of sheets of absorbent paper, such as blotting
paper or the like.
When made of pulp, I stamp the pipe out direct from the pulp
by suitable dies or moulds, which eliminate the liquid in the pulp and form the pipe
into the required shape, after which the pipe is dried in an oven or otherwise.
In order to prevent the burning tobacco from setting fire to the paper pulp, the
actual bowl may consist of a thimble of porous earthenware placed in the pulp
bowl. The mouth-piece may be of the usual description, and is fixed to the pipe
by means of a sliding or screwed ferrule, or by tapering the end of mouth-piece,
ره

page_text: whereby it can be held on the stem by friction. By withdrawing the mouth-piece from
the pipe, a fresh absorbent pipe can be substituted. The porous earthenware bowl
can also be taken out of the old pipe and added to the new one, or, as these bowls
can be made extremely cheaply, it can be thrown away, if desired, with the
absorbent part of the pipe. The pulp can be dyed or coloured to any desirable
shade. prefer, however, not to dye the pulp but to colour the pipe, after it is
made, on the outside only, as I have found that, in such case, the pipe is more
absorbent and there is no chance of any decomposition of the colouring matter and
causing of a disagreeable taste or poisonous effect.
The accompanying drawing shows, by way of example, a sectional elevation of
my absorbent pipe, in which
A, is the absorbent pipe B, the thimble of porous carthenware placed in the
pulp bowl and C, the mouth-piece. The upper part of the thimble 13 has a flange
which protects the top of the bowl from burning, while immediately beneath the flange
are threads b, which engage the interior of the pulp bowl through the contraction
of the latter or being dried. Any other suitable arrangement, however, may 'be
employed for securing the thimble B in the pulp bowl. The mouth-piece C also
may form part of the absorbent pipe instead of being fixed in the pipe as shown.
When the pipe is formed of sheets of absorbent paper, these sheets are wrappeil
round parallel or taper cores, one core being used for forming the bowl of the pipe
and another core, of smaller diameter, being used in forming the stem.
The paper
is wrapped tightly round and round these cores, until the required thickness of
material is obtained, and the paper is then cemented or otherwise fastened at the
end to prevent it unwrapping.
The cores are removed, a plug is inserted in the bottom of the larger wrapping
of paper, so as to form the tobacco bowl, and the stem and bowl are secured
together by means of cement or in any other suitable manner. The pipe may be
finished in a lathe or by any other tool or pressed between dies, whereby it is made
to assume any suitable shape or form.
The tobacco pipe of this invention, besides being absorbent, is very light, and is
practically unbreakable.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what I
claim is :-
1. The manufacture of tobacco pipes from wood or paper pulp or the like,
stamped or formed while the pulp is soft into the required shape, and afterwards
dried and hardened in an oven or otherwise.
2. Forming a tobacco pipe of the kind described with a tobacco bowl of porous
carthenware placed in the cavity of the pulp or paper bowl and secured thereto
by projecting threads engaging the interior of the said bowl substantially as
described.
3. The manufacture of tobacco pipes in whole or in part of wood or paper pulp
or the like or of sheets of absorbent paper substantially as and for the purpose
described.
