AN IMPROVED PIPE FOR SMOKING
Year: 1884

page_text: HENRY TAIT Mall House Musselburgh Midlothian Papermaker do hereby declare
the nature of my invention for AN IMPROVED PIPE FOR SMOKING to be as
follows:-
The improvement claimed lies in the construction of the stem, A which, instead
of having the usual straight bore is grooved spirally on the outside and is provided
with a tightly fitting cover B.
The cover B fits tightly all round on the outside face of the screw of Stem A.
The groove C dips near the bowl F down into the heart of the Stem A and this
passage D extends to the inside of the bowl F. And at the other end of stem A
groove C opens into the small chamber G inside of Cover B out of which opens the
bore of mouthpiece E.
The pipe may be composed of only two parts viz bowl F and stem A in one and
cover B with mouthpiece E attached.
Cover B with mouthpiece E attached draws off and on stem A from and towards
bowl F. The wide end of cover B forming a close joint with bowl F. This joint
need not be perfectly air tight as there is no connection between it and groove C.
It is advantageous but not absolutely necessary that both stem A and cover B
should be of a conical shape, as shown in drawing, tapering gradually from bowl F
to mouthpiece E so as to secure a good fit and prevent wear in removing and
replacing the cover B.
It may be unnecessary to make provision for wear, but, the small chamber G in
the end of cover B next to mouthpiece E is left to allow of cover B being pushed
further on to stem A in the event of wear.
Provision can be made at the other end by a slight check into bowl F to admit
of cover B being pushed on to the requisite tightness.
The advantages are as follows:-The smoke leaving bowl F by passage D follows
groove C round & round stem A thus travelling a much longer distance than in an
ordinary pipe although the stem is no longer.
"
The smoke when it reaches the mouth is consequently cooler and the juice of the
tobacco less liable to reach the mouth.
Moreover the stem A can be readily cleaned as, when cover B is pulled off the
groove C through which the smoke passes is exposed.
The ready way in which cover B can be removed will be found invaluable while
the pipe is in use for by taking it off a few seconds the stem A is cooled and
thoroughly ventilated.
'
The above principle of stem with cover to fit is claimed also for cigar and
cigarette holders.

SPECIFICATION.
I HENRY TAIT Mall House Musselburgh Midlothian Papermaker, do hereby
declare the nature of my invention for AN IMPROVED PIPE FOR SMOKING and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The drawing accompanying the provisional specification shows the construction
of the pipe to be as follows.
The stem A. of a conical shape tapering gradually from bowl F towards mouth-
piece E and grooved spirally on the outside (see groove C).
The cover B is made to fit so as to secure a close joint all round on the outside
face of the screw of stem A.
The groove C dips down into the heart of stem A at an angle and this passage D
extends to the inside of bowl F.
At the other end of stem A groove C opens into the small chamber G inside of
cover B out of which opens the boro of mouthpiece E.
The pipe may be composed of only two parts viz bowl F and stem A in one and':
cover B with mouthpiece E attached.
Bowl Fis of the usual description.
Cover B with mouthpiece E attached draws off and on stom A from and towards
bowl F, the wide end of cover B forming a close joint with bowl F. This joint
need not be perfectly air-tight as there is no connection between it and groove C.
The smoke leaving bowl F through passage D and following groove C has to
travel a much longer distance than in an ordinary pipe although the stem is no
longer. The smoke when it reaches the mouth is consequently cooler and the juice
of the tobacco less liable to reach the mouth.
To accomplish the end in view so far, it is unnecessary that the stem and cover
should be of a conical shape, but to prevent wear by friction in removing and
replacing cover B it is desirable that the stem and cover should be tapered.
A permanent fit is necessary for if the smoke can escape at the reverse end of
stem to that at which it enters without travelling the full distance of groove C the
object aimed at is defeated.
The friction caused by removing and replacing cover B may cause some wear but
the small chamber G in the end of cover B is left not only to act as a trap for
juice but also to allow of cover B being pushed on to the requisite tightness.
Provision is made at the other end by a slight check into bowl F to receive wide
end of cover B to the required extent.
.
On the other hand, if, by an accumulation of matter between stem and cover
or by the swelling of wood or other material of which theso may be composed, the
cover cannot be pushed on beyond a certain point, the joint will still be good.
Stem A can be readily cleaned; as when cover B is pulled off the groove C through
which the smoke passes is exposed.
The ready way in which cover B can be removed will be found invaluable while
the pipe is in use, for by taking it off for a few seconds the stom is cooled and
thoroughly ventilated.

page_text: The groove instead of being spiral may be cut into stem longitudinally i,e with
grooves running lengthwise from and towards bowl F, each length of groove
turning into the next to form a continuous groove.
The last length of said groove opening out into chamber G.
The above principle of stem with cover to fit is claimed also for cigar and
cigarette holders.
For said holders a cup to receive the end of cigar or cigarette takes the place of
the pipe bowl.
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
1st A stem for pipe, cigar or cigarette holder, with a continuous groove on its
surface with a cover or jacket to fit closely upon the elevated portion of the stem,
2nd The use of stem and cover of a conical shape as described.
