PROVISIONAL SPECIFICATION.
Improvements in and connected with Tobacco Pipes.
I, DANIEL JOSEPH FLEETWOOD of 12 Plough & Harrow Road, Edgbaston
in the City of Birmingham & County of Warwick Gentleman do hereby declare
the nature of this invention to be as follows:-
When the material employed is clay the bowl and stem of the pipe are moulded
so as to produce as large a chamber as possible for the condensation of the nicotine
and for this purpose the bore or hollow of the stem is continued under the bowl in
order to form a cavity between the bottom of the bowl and the inner surface of the
hollow stem.
For the discharge of the nicotine a vent may be opened in the underside of the
chamber or cavity the stopper of which will form the heel of the pipe.
Or a vent or duct may be obtained by continuing the bore or hollow of the stem
along or part of the way along the bowl.
This may be effected by forming externally a half bead the counterpart of which
may be within the bowl the extra thickness so produced being hollowed to form a
vent or duct communicating with the chamber or cavity beneath the bowl. This
vent or duct may be closed by a lid or stopper.
Pipes made according to the foregoing description and clay pipes generally may
be coloured or dyed wholly or in part by aniline or other suitable dyes or the clay of
which they are to be made may be coloured before it is moulded.
The pipes may be moulded in any suitable plastic material or they may be made
of wood or other non-plastic material suitable for tobacco pipes.
When the mouthpiece is of smaller diameter than the stem and the metal mount
employed requires to be deeply domed the metal mount may be shaped by drawing
it solid out of sheet metal and piercing the dome for the reception of the mouth-
piece.
Dated this Sixth day of November 1891.

COMPLETE SPECIFICATION.
Improvements in and connected with Tobacco Pipes.
I, DANIEL JOSEPH FLEETWOOD of 12 Plough & Harrow Road Edgbaston
in the City of Birmingham and County of Warwick Gentleman 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:-
When the material employed is clay the bowl and stem of the pipe are moulded
so as to produce as large a chamber as possible for the condensation of the nicotine
and for this purpose the bore or hollow of the stem is continued under the bowl
in order to form a cavity between the bottom of the bowl and the inner surface of
the hollow stem.
For the discharge of the nicotine a vent may be opened in the underside of the
chamber or cavity the stopper of which will form the heel of the pipe. Or a vent
or duct may by obtained by continuing the bore or hollow of the stem along or
part of the way along or up the bowl. This elongation will in horizontal section
represent externally a half bead the counterpart or a portion of the counterpart of
'מ

page_text: which may if desirable be within the bowl the extra thickness so produced being
hollowed to form the vent or duct communicating with the chamber or cavity
beneath the bowl. This vent or duct may be closed by a lid or stopper.
Fig. I. in the accompanying drawing represents in section a bowl & stem made
according to my invention. The bore or hollow (b) of the stem is carried under
the bowl (a) and continued along or up the bowl to form the vent or duct (c).
Fig. II. represents the stopper I prefer to employ especially for clay bowls.
The ball top (d) or one rounded on the under side when in place makes a sufficiently
air-tight joint and the elasticity of the spring (e) in which the stopper terminates
prevents damage to the vent or duct (c) which being of breakable material would
be endangered by the use of a solid taper peg.
Fig. III. shews the bowl with the stopper (Fig. II.) in its place.
Fig. IV. is a bowl mounted with a lid or stopper with the object of rendering the
pipe self contained by attaching the stopper to it in the form of a lid. The half-
hoop (f) is held by pivots or trunnions to the metal mount (g) and the lid or
stopper (h) is carried loosely in a groove or shaped opening (1) formed on the
half-hoop (f) to ensure to the lid or stopper (/) sufficient play in accommodating
itself to the radius and for adjustment into the vent or duct (c) this lid or stopper
terminates in a short spring (j). The springs (e. Fig. II. & j. Fig. IV.) in which
both lid & stopper terminate hold the lid and stopper in place.
This mount is secured to bowls other than clay in the ordinary manner but in its
adaptation to clay extra care must be taken in the moulding of the bowls and when
burnt those which are the most suitable for mounting are to be selected. I prefer
in such cases to make the mount of steel nickel plated. A steel band open at the
part intended to fit over the vent or duct (c) may be sprung into a groove repre-
sented at k. Fig. VI. and to this steel band the half-hoop (f. Figs. IV. & V.) may
be fitted as already described. The slightly projecting ends of the pivots or
trunnions fit into depressions or into grooves formed in the clay and keep the
mount steady. Instead of the lid or stopper described a flat lid or stopper or one
slightly dished or a lid lined with asbestos or other suitable material and provided
with a spring to keep it down on the vent or duct (c) may be employed.
Clay pipes made according to the foregoing description and clay pipes generally
may be coloured stained or dyed by aniline or other suitable dyes. This I do by
immersion and by preference I use an aniline mixture of from 1% to 3% strength
and continue the immersion about twenty minutes.
The pipes may be moulded in any suitable plastic material or they may be made
in wood or other non-plastic or semi-plastic material suitable for tobacco pipes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is:
1. In moulding the bowls and stems of clay tobacco pipes the construction of a
vent for the condensed nicotine substantially in manner herein described and
illustrated at Fig. 1 in the accompanying drawing.
2. The spring stopper substantially as and for the purpose specified.
3. In a clay tobacco pipe with nicotine vent the combination of a steel or other
band and half-hoop carrying a lid or stopper substantially as described and
illustrated.
4. Constructing tobacco pipes in wood or other material with a vent for the
condensed nicotine substantially as herein described and illustrated at Fig. 1.
5. In the construction of tobacco pipes in wood or other material as in Claim 4
the combination of a metal mount and half-hoop carrying a lid or stopper sub-
stantially in manner herein described and illustrated at Fig. IV.
6. In the moulding or construction of tobacco pipes as in Claims 1 and 4 the
combination of a metal mount carrying a flat lid or one dished or a lined lid
substantially as and for the purpose herein described.

described.
8. The improvements in and connected with tobacco pipes as herein set forth
and described.
