PROVISIONAL SPECIFICATION.
Improved Attachment for the Mouthpieces of Tobacco Pipes.
I, NEHEMIAH JAMES LEWIS of 18, Railway Terrace Great Harwood near
Blackburn Lanes. do hereby declare the nature of this invention to be as
follows:-
My invention consists of a short india-rubber tube made to clip over the mouth-
piece of any ordinary pipe, and this tube is fitted with a perforated celluloid
termination which is arranged to fit up against the mouthpiece of the pipe as
closely as possible. The object and intention of this invention is to prevent small
pieces of tobacco or foreign matter from getting into the mouth of the smoker.
will easily be understood that the perforated celluloid or zylonite cap will intercept
any particles of matter from getting into the mouth of the smoker.
It
When the perforations have become blocked the whole attachment may be easily
removed from the mouthpiece and cleansed and replaced. Athough celluloid or
zylonite are the materials I intend to employ in connection with the rubber cap [
do not limit myself to these materials.

COMPLETE SPECIFICATION
Improved Attachment for the Mouthpieces of Tobacco Pipes.
I, NEHEMIAH JAMES LEWIS Contractor of No. 18 Railway Terrace (treat
Harwood, near Blackburn, Lancashire 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 an improved attachment for the mouthpieces of tobacco
pipes, and has for its object, the prevention of tobacco dust, ash, and other foreign
matter, from entering the mouth of the smoker, and also the splitting up of the
stream of tobacco smoke, which in the act of smoking comes up the stem of the
pipe, into several lesser streams, thereby distributing the force of the current of
smoke which enters the mouth of smoker, allowing the same volume to enter the
mouth of smoker, but with a wider spread of space.
In order that my said invention may more readily be understood, reference is
made to the accompanying sheet of drawings, in which
Figure 1 is a full sized elevation of my improved attachment to tobacco pipes,
attached to the mouthpiece of an ordinary pipe.
Figure 2 is a full sized section of the same.
Figure 3 is an elevation of the sieve or cap, (drawn four times full size).
Figure 4 is a plan of sieve or cap, (drawn four times full size).
Similar letters of reference indicate corresponding parts throughout the several
drawings.
A is an india-rubber tube made to clip around the mouthpiece of the pipe, with
the end X that fits upon the cap B contracted, so as to bind in and closely fit into
a groove made in the cap B which is marked G. The other end of the india-
rubber tube is fixed on to the mouthpiece of pipe, and held there by its own
elasticity.
-
It will be seen that when the india-rubber clip is so placed, it will by reason of
its elasticity keep the cap B as closely to the mouthpiece of pipe as possible.

page_text: B is a cap or sieve which is made to fit close to the stem end of pipe, and to
prevent the lower part of cap from stopping up the bore of pipe, I have placed
projections P to the underside of cap B, which serve to keep the cone part of
cap B from coming so close to the bore of the pipe as to stop up the draught of
smoke from the bore of the pipe. Cap B on the underside, (immediately over the
bore of pipe) is shaped conically (C) so as to direct and facilitate the current of
smoke from the bore of pipe to the holes or perforations H which are situated
immediately below the projecting rim R around the cap. The projecting rim R
is made around the cap, so as when the india-rubber clip A is fitted to the cap, it
is thrown out or projected out by the projecting rim R, so as to allow the smoke
to pass freely between the india-rubber clip the part of cap B which is underneath
the rim R, and so on through the holes or perforations, and forward to the mouth
. of smoker.
It will readily be seen that the smoke, tobacco dust, ash and other foreign
matter in passing up the bore of pipe, will be split up into as many currents as
there are holes in the cap. (I have put three holes H in the sketch, but I do not
bind myself to either more or less than three holes.) The smoke etc. will be
'directed along the cone shaped part C, towards the sides at which the holes are
situated, when the solid matter will fall against the side of the india-rubber, and
allow the smoke to pass out of the holes. The products being divided into three
separate currents below the cap, will on re-uniting above the cone C in the cap,
break their force, and enter the mouth of smoker with the force wider spread, and
consequently less felt.
In the manufacture of the cap B I do not limit myself to celluloid and zylonite,
but retain the right to make it out of any suitable materials, such as vulcanite,
wood, glass, porcelain, etc.
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
1st. The using of the perforated cap above the mouthpiece of pipe.
2nd. The shape of the cap which can be either oblong or circular.
3rd. The using of the india-rubber clip with contracted end to bind the mouth-
piece of pipe and cap together, as used in this manner.
4th. The oblong holes or perforations under the projecting rim.
5th. The projecting rim around the cap.
6th. The projections at the base of cap to prevent contact of mouth of hore of
pipe with apex of cone underneath the cap.
7th. The conical shaped underside of cap.
