IMPROVEMENTS IN PIPES FOR SMOKING
Year: 1884

page_text: I HENRY EDWARD NEWTON of the Office for Patents, 6 Brean's Buildings
Chancery Lane in the County of Middlesex Civil Engineer, do hereby declare the
nature of my invention for IMPROVEMENTS IN PIPES FOR SMOKING and in what
mauner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
These improvements have for their primary object to prevent the nicotine formed
in the bowl while the pipe is being smoked coming in contact with the lips or
mouth of the smoker, thus obviating the evil of such contact and doing away with
one great objection to smoking. The improvements also relate to special means
for regulating the draft so that wet or coarse tobacco may be smoked with ease,
and also embrace certain contrivances for keeping the pipe clean.
The invention may be thus briefly described :-
The bowl proper in which the tobacco is placed for consumption is set in and
hinged to a lower bowl, and has its lower part perforated so as to afford the
necessary draft which may be regulated if desired, or the lower part may be
provided with a perforated plug for the same purposes.
Through the stem of the pipe is taken a small draft tube the inner end of which
projects into the lower bowl but does not come in contact with the tobacco
receptacle or its stopper. To ensure this a shield is sometimes secured to the
stopper so as to be interposed between it and the end of the tube.
This lower bowl is lined with metal, foil or any other substance which
will prevent the nicotine dropping into the bowl, permeating the substance (wood,
clay &e) of which it is composed; or a metal, glass or porcelain cup which can
easily be taken out and cleaned may be inserted.
For full comprehension of this invention reference must be had to the annexed
drawing forming part of this specification, in which Fig. 1. is a side view of the
pipe; Fig: 2 a longitudinal sectional elevation of same, showing it open for the
purpose of taking out and cleaning the inner bowl; Figure 3 is a side elevation
partly in section showing a modification of the construction, and Figure 4 is a
similar view shewing a further modification in which one tobacco holder can be
substituted for another.
Similar letters of reference indicate like parts.

page_text: A is the lower bowl which is usually as shown made in one with part of the
stem and of any desired material This is formed with a seat A of rubber, cork &c
so as to make a tight joint with the tobacco holder proper B which is hinged to it
as shown at b and provided with any suitable fastening device B'.
In the bottom of this holder B is formed a seat for a movable perforated plug C,
or the bottom itself may be perforated as shown in Figs. 3 and 4, the number and
size of the holes c regulating the draft as will be hereinafter more particularly
alluded to. In Fig. 4 the holder B is shown as set in a seat D which is binged
to A as described with relation to B. By this arrangement one kind of tobacco
receptacle can be substituted for another without otherwise altering the pipe.
The inside of the bowl A is lined with foil, metal, or any other material which
will hold the nicotine and prevent it from passing into the substance of the pipe, or
a bowl E of glass, metal or similar substance which can be easily withdrawn,
cleansed and replaced, may be introduced.
F is the draft tube passing through the stem of the pipe and secured if desired
to the mouthpiece proper. The end of this projects, as shown, into the bowl A but
not far enough to touch the perforated stopper C or the bottom of B, thereby
preventing any nicotine which may have formed in B and dropped into the bowl A
passing along the stem.
To perform this more effectually a shield as shown at G may be attached to the
stopper C or perforated bottom of B so as to be interposed between the draft
apertures c and the end of F.
From the foregoing it will be seen that while it is impossible for the nicotine to
pass from B along the draft tube F to the mouth of the smoker, a perfectly free
draft is given through the bowl A, and that by adopting. the construction shown in
Fig. 3. the sectional area of this draft can be varied to suit the kind of tobacco
desired to be smoked, by opening or stopping some of the holes.
By turning back the bowl B after smoking the pipe will cool far more quickly
than at present, and the smell of stale tobacco will pass off at once, especially if the
inner bowl E be taken out and cleansed.
If it be desired to colour the bowl A this bowl E or the lining corresponding
thereto can be omitted, but in such a case great care must be taken to cut off the
nicotine from passing along the stem.
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
1. In a pipe for smoking, the bowl A interposed between the stem and the
tobacco holder proper, as and for the purposes described.
2. The combination with the bowl A and draft tube F, of the bowl B perforated
at bottom and binged to A. as and for the purposes set forth.
3. The combination of the bowls A and B and seat D substantially as herein
described.
4. The combination with the bowl A of the lining or cup E.
5. The combination with the bowl B having perforated stop or bottom, bowl A,
and draft tube F, of the shield G as and for the purposes described.
