PROVISIONAL SPECIFICATION.
Improvements in and connected with Tobacco Pipes.
I, NEIL MACPHAIL, of 175 St. Vincent Street Glasgow, Wholesale Stationer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to a new or improved mode and means whereby the smoke
channel in both the stem and mouthpiece of tobacco pipes may be kept clean and
freed from nicotine, saliva, or other accumulations or obstructions throughout the
entire length of both. This is accomplished in the following manner. Inside the
smoke channel of the stem and mouthpiece is placed a rod extending throughout
their entire length. This rod is made of less thickness than the diameter of the
smoke channel. On the end of the rod and attached to it there is a round boss or
knob or the like circular projection of the exact diameter of the smoke channel and
fitting it closely. The rod with the boss or knob attached remains permanently in
the pipe during smoking, and is withdrawn with facility as often as required by
means of a small round knob fixed to the end of it outside the mouthpiece. This
knob prevents the smoke striking directly on the tongue or any saliva entering the
mouth-piece. The smoke channel is made to extend from the stem into the head
of the pipe, below the bowl where the knob end of the rod lies, beyond the aperture
or apertures which lead from the bowl to the channel in the stem; and thereby the
smoke gets free vent to the mouth of the smoker while the rod, with boss or knob
attached, is in the pipe. When withdrawn the boss or knob clears out before it,
throughout the entire length of the stem and mouthpiece, all nicotine or other
accumulations, leaving the smoke channel clean from end to end of the pipe. On
the rod and knob being wiped clean they are replaced in the pipe as before.
The improvements are also applicable to pipes having bent stems.

COMPLETE SPECIFICATION.
Improvements in and connected with Tobacco Pipes.
I NEIL MACPHAIL, of 175 St. Vincent Street, Glasgow, Merchant, 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:-
My invention relates to a new or improved mode and means whereby the smoke
channel in the mouthpiece, stem, and head of tobacco pipes may be kept clean and
freed from nicotine, saliva, or other obstructions throughout its entire length.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended one sheet of drawing which I will now proceed to
describe.
Figure 1 is a section of a pipe showing my improvements.
In the
Figure 2 is an end view of the mouthpiece of the pipe showing notches or
openings through which the smoke passes into the mouth of the smoker.
figure two notches or openings are shown, but of course their number may vary.
Inside the smoke channel A of the stem and mouthpiece is placed a rod B extending
throughout its entire length. This rod B is made of less thickness than the
diameter of the smoke channel A. On one end of the rod B taere is a knob or
TD C

page_text: round boss C of the exact diameter of the smoke channel A and fitting it closely.
The rod B with the boss or knob C attached remains in the pipe during smoking,
and is withdrawn with facility as often as required by means of a small knob D at
the end of it outside the mouthpiece. This knob D also prevents saliva entering
the mouthpiece. The smoke impinges on the knob in its passage through the
notches or openings e and is diffused or radiated while entering the mouth. The
smoke channel is made to extend from the stem into the head of the pipe, below the
bowl where the end of the rod with the boss or knob C lies beyond the aperture f
This aperture leads from the bowl G in the head of the pipe to the smoke channel,
and by this aperture and the channel the smoke gets free vent to the mouth of the
smoker while the rod B with the boss or knob C attached is in the pipe. When
withdrawn the boss or knob C clears out before it throughout the entire length of
the smoke channel all nicotine, saliva, or other obstructions, leaving the smoke
channel A clean from end to end. On the rod B being wiped clean it is replaced
in the pipe as before.
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
clain is
1. In smoking pipes the rod B passing throughout the entire length of the smoke
channel and beyond the aperture leading from the bowl to that channel with the
knob or boss C.at the inner end and the knob D at the other and outside the
mouthpiece, all substantially as and for the purposes herein before described and
shown on the accompanying sheet of drawings.
2. In sinoking pipes the knob D and notches or openings e at the orifice of the
mouthpiece for diffusing the smoke and preventing any saliva entering the mouth
substantially as herein before described and shown on the accompanying sheet of
drawings.
