Improvements in Pipes for Smoking Tobacco.
I, RICHARD GEORGE HOOPER TOMSON, of Manston House, Moss Road,
Urmston, in the County of Lancaster, Manager, do hereby declare the nature of
this invention to be as follows:-
:-
This invention is designed with the object of providing a tobacco pipe the stem
of which can be easily cleaned.
I bore out the stem of the pipe to a size considerably larger than the ordinary
bore from the end into the head or bowl so that there is no small or narrow
passage. Into the hole so bored I fit an inner core rod or bar one end of which
fits into the hole bored into the head of the pipe and the other end into the end
of the stem. With the exception of the ends which fit the two ends of the stem
this core does not fill up the internal bore of the stem but leaves a considerable
space and the smoke passes round it as no hole runs longitudinally through it.
The core is attached to or formed in one piece with a mouth piece of bone,
vulcanite, amber, or other suitable material and the end furthest from the mouth
piece is in the shape of a disc or flange with a hole through it. The central part
of the core is preferably flat to present a considerable surface but it may be round
or of other shape.
Instead of the mouthpiece end of the core fitting into the end of the stem the
end of the mouthpiece may abut against the end of the stem and be held in
position by a metallic band or the like.
Most of the moisture from the tobacco which condenses will condense on this
core which can be easily and quickly cleaned by simply rubbing it on a piece of
cloth or paper after it has been withdrawn from the pipe stem while the with-
drawing of it removes any moisture which may have condensed on the inner side
of the bore by the disc or flange on the end.

COMPLETE SPECIFICATION.
Improvements in Pipes for Smoking Tobacco.
I, RICHARD GEORGE HOOPER TOMSON, of Manston House, Moss Road.
Urmston, in the County of Lancaster, Manager, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement-
This invention is designed with the object of providing a tobacco pipe, the stem
of which can be easily cleaned.
It consists essentially in forming the pipe with a wide chamber or hole extending
the length of the stem into the bowl or head of the pipe, and with a solid inner
core or rod having a head or flange on one end which fits into and fills the large
hole bored in the bowl or head, and is provided with a small smoke passage, and at
the other end is attached to the mouth piece.
It will be fully described with reference to the accompanying drawings, in
which, as an example, one shape of pipe is shown constructed in accordance with
my invention.

Fig. 4. Side elevation of centre core removed from stem.
Fig. 5. Plan of centre core.
The stem A. of the pipe I bore out from end to end to a size considerably larger
than the ordinary bore, forming a chamber a which extends into the head or
bowl B, leaving no small or narrow passage in the stein A.
Into the wide hole or
chamber a,
I fit an inner solid core, rod, or bar C, of lesser dimensions than the
chamber a to allow room for the passage of smoke around it, between it and the
inner side of the stem. The inner end of the core C I provide with a flange or
head D, which closes the end of the chamber a at its entrance into the bowl B.
The flange or head D is provided with a small hole or smoke passage d, through
which the smoke enters into the chamber a, around the core C.
exception of the small passage d in the flanged head D, there is no hole through
the core C.
With the
The core C is attached at its outer end to, or may be made in one piece with the
mouth piece E. The core C I prefer to make of box wood or similar material, and
the mouth piece E may be made of vulcanite, amber, bone, or other suitable
material, but if desired the core C may be made of the same material as the mouth
piece E. The central part of the core is preferably flat to present a considerable
surface, but it may be round, or of other shape.
The mouth piece end ate of the core C may be made to fit into the end of the
chamber a of the stem A as shown, the end of the stem being strengthened by a
metallic band F, or the core may fit completely into the mouth piece E, and the
latter abut against the end of the stem and be held in position by a metallic band
or the like.
Most of the moisture or nicotine from the tobacco, which condenses inside the
stem of the pipe, will collect or condense on the core C, and the stem of the pipe
can be very easily and quickly cleaned by removing or withdrawing the core C,
and the moisture or nicotine removed therefrom by rubbing it upon a piece of cloth
or paper, while the withdrawing of it removes any moisture or nicotine-which has
collected on the inner sides of the chamber a by the flanged head D scraping
against them.
There is thus no occasion to use anything to pass through the bore of the pipe
to clean it, as the only small hole is the hole d which is removed, and if required
can be cleaned whilst the core is removed.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what I
claim is
A pipe having a wide chamber or hole extending the length of the stem into the
head or bowl, and provided with an inner solid core or rod of lesser dimensions, on
one end of which is formed a head or flange with a small smoke passage which fits
the opening made in the bowl, and at the other end is attached to the mouth piece
substantially as described.
