PROVISIONAL SPECIFICATION
Improvements in and relating to Tobacco Pipes, and Cigar and
Cigarette Holders
I, ANDREW WESTWATER, of 16 Millerbank Street, Springburn, in the County
of the City of Glasgow, Engineer, do hereby declare the nature of my invention
to be as follows
This invention has reference to an improved method and construction of
mouth piece applicable to tobacco pipes and cigar and cigarette holders for
preventing the saliva of the mouth entering the bowl of the pipe or stem of the
holders
According to my improvements I form the front or mouth end of the mouth
piece as a hollow chamber and lead a projecting central small bore stem or tube
fiom the smoke channel some distance into same, but having some space between
the end of small bore stem and the outer end of mouth piece
Slots or openings would be formed through the shell of mouth piece into the
aforesaid chamber, preferably set at an angle at its inner end
By this method when the smoker puffs away, cold air is drawn in through
these openings in saliva chamber, and any saliva passing from the mouth into
the saliva chamber is instantly ejected into the smokers mouth through a hole
or holes in lower part of saliva chamber, so that none can accumulate or piss
into the stem or bowl
The end of small bore stem may be open, or it may be closed or fitted with
a screw plug and holes or openings be formed in the stem behind this through
which the smoke would be drawn And openings may lead into a separate
nicotine trap chamber formed in stem the openings being either formed through
the shell of stem or on an extended inne fluted part of mouth piece formed of
wood or vulcanite and passing through stem to nicotine trap chamber, the air
passing from Joint of mouth piece and stem

COMPLETE SPECIFICATION
Improvements in and relating to Tobacco Pipes, and Cigar and
Cigarette Holders
I, ANDREW WESTWATER, of 16 Millerbank Street, Springburn, in the County
of the City of Glasgow, Engineer, do hereby declare the nature of my invention
and in what manner the same is to be performed to be particularly described
and a certained in and by the following statement in writing, that is to say
-
This invention has reference to improvements in and relating to tobacco pipes
and cigar and cigarette holders
And in order that my said invention and the manner of carrying same into

page_text: practice may be properly understood, I have hereunto appended an explanatory
sheet of drawings in which
Figure 1 represents a sectional elevation of a complete pipe as fitted in
accordance with my improvements
Figure 2 is a detached view of the mouthpiece and inner fittings and Figure 3 is
an end view of Figure 2, while Figure 4 shows a detached view of the inner end
part of Figure 2 with nicotine absorbing paper coiled round same
Figure 51s a sectional view, corresponding to but somewhat modified from that
shown in Figure 2, and
Figure 6 is a sectional view of a cigarette or cigar holde
Referring to these drawings
-
The inner end part of mouthpiece A which would preferably consist of vulc inite
or wood is made of less diameter to fit within the stem C of pipe, and is formed
with a series of longitudinal flutes or grooves b so as to permit of a passage for the
inlet of air to the nicotine trap chamber C', the air flowing in through slits or
openings at the junction part 2 of stem and widened body of mouthpiece A, at
the part where the metal ring C³ overlaps A hollow plug c of boxwood or the
like would preferably have one of its narrowed ends inserted in the inner
enlarged bored end of mouthpiece, while its other end c² would project within the
trapping chamber C', and by this means the air diawn in along the grooves 6 will
flow into trapping chamber C¹ and through the nipple c² uto mouthpiece smoke
channel A¹ A coil of paper ³ may be placed over the nipple c² as shown in
Figure 4 to absorb any nicotine or juice
In the arrangement shown in Figure 5 the end c² of hollow plug c is shown as
formed with an enlarged space, while a saliva chamber a is formed at front end of
mouthpiece A, having an orifice a² through which any saliva accumulating in said
chamber will be ejected or drawn back into the mouth and prevented from passing
through bore A¹ of mouthpiece A into bowl, and a nipple part a' would preferably
extend from bore into saliva chamber a
In the arrangement shown in Figure 6 which is suitable as a cigar or cigarette
holder, trapping chamber C is formed at inner end of mouthpiece and a hole b
is formed through shell for the inlet of air, while a saliva ejection hole a³ would be
formed at fiont end of mouthpiece
The projecting ribs d, d' are for being gripped by the teeth to form double
acting retaining bars for preventing saliva entering the bore hole A' of pipe
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
-
First In tobacco pipes and cigar and cigarette holders, the arrangement and
use of a fluted or grooved end on mouthpiece to fit into stem of bowl and form air
inlet passages, substantially as herein described in reference to and shown in the
accompanying diawings
Second In tobacco pipes and cigar and cigarette holders, the arrangement and
use of a saliva ejection orifice at fiont end of mouthpiece substantially as herein
described in reference to and shown in the accompanying diawings
Third In tobacco pipes and cigar and cig rette holders, the combination of air
inlet, and saliva ejection orifices, substantially as herein described in reference to
and shown in the accompanying drawings
Fourth The constructing of the mouthpiece of pipes and cigar and cigarette
holders substantially as herein set forth
