DAVID THORPE LEE 1 Elm Tree Road St John's Wood, London County of
.Middlesex Artist do hereby declare the nature of my invention for THE IMPROVE-
MENTS IN TOBACCO PIPES to be as follows:-
A metal collar or ferrule fitted to the mouthpiece, heel, (nib), or bowl of pipe,
the said collar or ferrule tapered so as to push or fit into stem, bowl, or heel of
pipe The aforesaid collar or ferrule, being fitted with an inverse tube, or funnel,
thus forming a receptacle for retaining the moisture, caused when smoking, from
entering the bowl, thus preventing the stopping or clogging of stem, and so ensuring
free draught and dryness of tobacco to the last.

page_text: I DAVID THORPE LEE 1 Elm Tree Rd St John's Wood London, in the County
of Middlesex Artist do hereby declare the nature of my invention for IMPROVE-
MENTS IN TOBACCO PIPES and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
My invention consists of improvements in tobacco pipes, its purpose being to
provide a simple and efficient method of preventing the moisture and nicotine
entering the bowl of the pipe, or the mouth of the smoker, and also in some
degree to confine the heat produced by the burning tobacco to the centre of
combustion.
In carrying out my said invention into practice, I provide a ferule, or tapered
tube, or tube partly tapered & partly globular into the widest end of the said tube
I fit the mouthpiece, the opposite end being fitted with an inverse tube or spigot
extending inwards towards the end of the aforesaid mouthpiece, but not so far as
to join it, by this means a chamber is formed through which the smoke is drawn
and into which, the moisture containing the nicotine is deposited. A modification
of this arrangement I apply to the heel or bowl of pipe.
The aforesaid ferule or tube may be made of any kind of metal that can be
adapted to it or of any material, such as ivory, horn, bone, vulcanite, or other
substance comparatively non-absorbent, and of slow heat-conducting properties.
When made of metal I fix in the spigot, or pack it round with asbestos either in
the form of cement or fibre, but I have found from experiments that the best
material to make both the ferule and the mouthpiece of is a composition composed
of, about equal parts of india rubber asbestos powder or fibre & a portion of
sulphur subjected to a sufficient heat in a vulcaniser to make it hard & capable of
receiving a fine polish, this composition I name Asbestos-vulcanite, which for the
purpose herewith specified I consider unequalled it being a very slow conductor of
heat, cool to the mouth & causing a greater deposit of the injurious oil distilled
from the tobacco.
The end of the mouthpiece which fits into the ferule or chamber I make
somewhat funnel or trumpet shaped this form obviating the bubbling usually
produced when smoking through a mouthpiece of the ordinary pattern.
In the accompanying drawing I have shown how my said invention may be
advantageously carried out.
Figure 1 shows partly in side elevation and partly in section my improved pipe
Like letters indicato corresponding parts throughout the drawing.
a is the bowl of the pipe, b is the ferule or chamber for the deposit of the
nicotine. c is the spigot through which the smoke passes. d is the mouthpiece
with end formed trumpet shaped the said mouthpiece is pulled out of the ferule to
empty away the moisture after smoking. It can be made either to telescope or to
screw.
Figure 2 shows a modification of the form of ferule and mouth piece.
Figures 3 & 4 shew in section the receptacle applied to the heel and bowl of
pipe, the inverse tube is fixed on to the pipe, upon which the receptacle is pushed
or screwed and removable at pleasure.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim, is,
First the novel and simple method of constructing a nicotine receptacle easily
attached and detached and forming part of what is generally known as a push

page_text: mouth piece and which can be applied to any kind of pipe bowl, stem or tube used
for the consumption of tobacco.
Second the employment of asbestos and india rubber treated in the manner as
heretofore described as a substance wherewith the said mouth piece or receptacle
may be constructed.
