Improvements in Pipes for Smoking
I, JOHN MC KENZIE, of 4 Palermo Street Springburn, in the City of Glasgow,
Pattern Maker, do hereby declare the nature of this invention to be as follows
This invention, which relates to pipes for smoking tobacco, has for its object the
provision of means whereby the formation of juice in the lower part of the bowl
and stem of the pipe is prevented
To that end I form an orifice through the bottom of the bowl whereinto I screw
or otherwise fit a plug having in it a small orifice through which air is admitted to
the tobacco in the bottom of the bowl Around this plug is an annular cavity
communicating with the bowl and the orifice in the pipe stem through which the
tobacco smoke is drawn The air drawn through the tubular plug into the bottom
of the bowl in the act of smoking prevents condensation of the vapour generated
by the burning of the tobacco and consequently avoids the formation of juice
Saliva from the smoker's mouth cannot pass beyond the annular cavity around
the plug into the bowl, but any of the saliva retaining devices usually fitted in the
stem may also be provided

I, JOHN MC KENZIE, of 4 Palermo Street, Springburn, in the City of Glasgow,
Pattern Maker, do hereby declare the nature of this invention and in what
manner the same 19 to be performed, to be particularly described and ascertained
in and by the following statement
This invention, which relates to pipes for smoking tobacco, has for its object the
provision of means whereby the formation of juice in the lower part of the bowl
and stem of the pipe is prevented
The invention is illustrated by the accompanying diawings,
Figures 1 and 2 being vertical sections of two modifications of the pipe and
Figures 3 and 4 an elevation and a plan respectively of a detail of the same
I form an orifice A through the bottom of the bowl B whereinto I screw, as
shewn by Fig 1, or push as shewn by Fig 2, or otherwise fit a plug having in
it a small central orifice D through which air is admitted to the tobacco in the
bottom of the bowl B Around this plug C the upper portion of which has vertical
grooves c formed around it as shewn particularly at Figs 3 and 4, is an annular
cavity E communicating by means of the grooves c with the bowl B and directly
with the orifice F in the pipe stem G through which the tobacco smoke is drawn
The air drawu through the tubular plug into the bottom of the bowl B in the
act of smoking prevents condensation of the vapour generated by the burning of

page_text: the tobacco and consequently avoids the formation of Juice Saliva from the
smoker's mouth cannot pass beyond the annular cavity E around the plug C into
the bowl B but any of the saliva retaining devices usually fitted in the stem may
also be provided
Instead of forming the upper portion of the plug with grooves c as described
the plug may at that part be made an easy fit and so make communication between
the pipe bowl B and the annular cavity E
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
-
A pipe for smoking furnished with a plug for admitting an to the bottom of the
bowl and otherwise constructed substantially as described with reference to the
innexed drawings
