I, THOMAS SENNETT of No. 16 Ravensdon Street Kennington Park Road, Surrey,
Architect and Surveyor do hereby declare the nature of my invention for IMPROVE-
MENTS IN THE CONSTRUCTION OF PIPES FOR SMOKING TOBACCO AND OTHER PLANTS
AND SUBSTANCES to be as follows:-
In constructing the Stem or Stem-and-mouth-piece of the pipe in such a manner
that the Continuity of the bore or smoke channel thereof is severed in two places, by
two separate intecepting chambers or traps, the object of which is to prevent the
Nicotine, Tobacco dust or other injurious or unpleasant matter from entering the
mouth and also to prevent the saliva from the mouth mingling with the Nicotine &c.
or entering the stem or bowl of the Pipe and to allow of the ready separation of the
parts for cleaning all in a manner not hitherto done.
In carrying out my Invention I preferably construct the Pipe in three pieces,
First The Bowl with suitable length of stem attached, Second, a middle or connecting
piece, and third the Mouth-piece; all centrally bored with a small bore in the usual
manner.
In both the Mouth-piece and Stem, at their intended junction with the middle piece,
I form the intercepting chambers (one in each) by widening the bore at these parts,
to as great a width or diameter as practicable, and to a suitable depth to make a
proper connection with the middle piece, and leave a clear intercepting chamber
beyond in each case.
The middle or connecting piece I preferably construct in the form of a double plug,
with an annular milled outside central stop, the plug on either side of such stop
being made to join on to into or over the stem and the mouthpiece respectively,
the bore of such double plug being continued beyond same at each end in the shape of
a short thin tube of a much less diameter than the plug adjoining.
By now fitting the above described parts together the pipe is complete, with the
bore severed in two places, by the two intercepting chambers, such chambers being
separated from each other by the double plug or middle connecting piece, and
effectually trapped against each other, by the short thin projecting tube at each end of

page_text: such said double plug, penetrating in each case (in the clear of the sides) one into
the nicotine chamber in the stem, and the other into the Saliva Chamber in the
Mouth-piece of the pipe.
The thin projecting tube penetrating the Nicotine intercepting chamber in the Stem,
I preferably construct with a stopped or partially stopt end, and bore close up to such
stopt end, two or more perforations penetrating the main bore at right angles
thereto, or I chamfer or splay off such stopt end, or part thereof, in two or more places
until the main bore is exposed, as an indirect, in lieu of a direct passage for the
smoke, and a further safeguard against anything unpleasant being drawn past the
plug into the mouth.
The fitting together of the various parts will be effected by the ordinary methods of
screw or push-and-pull joints.
The middle connecting piece or double plug, may in some instances, be in whole or
part so adapted as to be permanently fitted to or form part of the mouthpiece or stem
of the pipe.
In the case of a single push-joint pattern pipe, the stem of the pipe would be
hollowed out (the bore in part widened) as before described, for the Nicotine inter-
cepting chamber, and the intercepting chamber for the Saliva, would be contained in
the end of the push plug of the mouth-piece, which plug would by preference be of
metal, a thin short tube penetrating and also projecting from such hollow end of
push-plug would trap both chambers; or the push plug (hollow) might be so tapered
or reduced at the end as to allow of the omission of the thin tube in the Nicotine
Chamber, and the tube for the Saliva Chamber might be in construction made out of
the pierced end of the hollow metal push plug attached to the mouth piece, or vice
versa in the case of the push being on the stem in lieu of the mouth-piece.
In some instances I prefer to construct the two intercepting chambers trapped by
the double plug and short thin tubes, all in one piece, the ends of such middle piece
forming the open ends of the intercepting chambers, into which the stem & mouthpiece
would respectively screw or push into or over as desired.
It will be seen that the main feature of my Invention consists in the two distinct
receptacles for the Saliva and Nicotine divided from and trapped against one another
in the manner described so that the Saliva is confined (by one receptacle) to the
mouth-piece, and the Nicotine (by the other receptacle) to the Stem & Bowl of the
pipe.

I, THOMAS SENNETT of No. 16 Ravensdon Street Kennington Park Road Surrey,
Architect and Surveyor do hereby declare the nature of my invention for IMPROVE-
MENTS IN THE CONSTRUCTION OF PIPES FOR SMOKING TOBACCO AND OTHER PLANTS
AND SUBSTANCES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
In constructing the stem or stem and mouthpiece of the pipe in such a manner
that the continuity of the bore or smoke channel thereof is severed in two places by
two separate intercepting chambers or traps, the object of which is to prevent the
Nicotine, Tobacco dust or other injurious or unpleasant matter from entering the
mouth whilst smoking and also to prevent the saliva from the mouth mingling with
the Nicotine &c. or entering the stem or bowl of the pipe, and to allow of the ready
separation of the parts for cleaning all in a manner not hitherto done.
In carrying out my Invention I preferably construct the pipe in three pieces, 1st
the bowl with suitable length of stem attached, (see drawing No. 1). 2nd a middle
or connecting piece (see drawing No. 2.) and 3rd the mouthpiece (drawing No. 3.)
all centrally bored with a small bore in the usual manner.
In both the mouthpiece and stem, at their intended junction with the middle piece,
I form the intercepting chambers d. e. (one in each) by widening the bore at these
parts to as great a width or diameter as practicable and to a suitable depth to make a
proper connection with the middle piece and leave a clear intercepting chamber
beyond in each case.
The middle or connecting piece (drawing No. 2.) I preferably construct in the
form of a double plug b. b. with an annular milled outside central stop (a.) the
plug (b.) on either side of such stop being made to join on to into or over the stem
and mouthpiece respectively, the bore of such double plug being continued beyond
same at each end in the shape of a short thin tube (c.) of a much less diameter
externally than the plug adjoining.
This central piece I may construct in one piece of Vulcanite or other substance,
or the projecting tubes (c. c.) may be constructed separately and fitted into such
aforesaid double plug.

page_text: By now fitting the above described parts together, either with screw joint
connections as shewn, or otherwise, the pipe is complete as shewn in side elevation
(Drawing No. 4.) with the bore severed in two places by the two intercepting
chambers d. e. Such chambers being separated from each other by the double plug
or middle connecting piece (a. b. b.) and effectually trapped against each other by the
short thin projecting tube (c.) at each end of such said double plug penetrating in
each case in the clear of the sides, one into the nicotine chamber (d.) in the stem and
the other into the Saliva chamber (e.) in the mouthpiece of the pipe.
The thin projecting tube (c.) penetrating the Nicotine intercepting chamber (d.)
in the stein I preferably construct with a stopped or partially stopped end
(see drawing No. 5.) and bore close up to such stopped end two or more perforations (f.)
--penetrating the main bore at right angles thereto or I chainfer or splay off such
stopped end or part thereof in two or more places (see drawings No. 6 & No. 7.)
until the main bore is exposed (9. g.) as an indirect in lieu of a direct passage for the
smoke and a further safe-guard against anything unpleasant being drawn past the
plug into the mouth.
The fitting together of the various parts will be effected by the ordinary methods
of screw or push and pull joints.
The middle connecting piece (drawing No. 2.) or double plug may in some instances
be in whole or part so adapted as to be permanently fitted to or form part of the
mouthpiece or stem of the pipe.
In either case whether forming part of the stem (drawing No. 8.) or mouthpiece
(drawing No. 9) the annular central stop (a.) may be omitted and when it forms
part of the stem (drawing No. 8.) I prefer to omit the nicotine chamber (d.) in
such stem.
in the case of a single push joint pattern pipe (drawing No. 10.) the stem of the
pipe would he hollowed out as before described for the nicotine intercepting chamber (d.)
and the intercepting chamber for the saliva (e) would be contained in the end of the
push plug of the mouthpiece. which plug would by preference he of metal, a thin
short tube penetrating into and also projecting from such hollow end of push plug
would trap both chambers (d. e) or the hollow push plug might be so tapered or
reduced at the end as to allow of the omission of that part of the thin tule penetrating
the nicotine chamber (d.) and the tube for the saliva chamber (e.) might be in
construction made out of the pierced end of the hollow metal push plug attached to
the mouthpiece (drawing No. 11.) or vice versa in the case of the push plug being on
the stem in lieu of the mouthpiece.
In some instances I prefer to construct the two intercepting chambers (d. e.)
trapped by the double plug and short thin tubes all in one piece (drawing No. 12.) the
ends of such middle piece forming the open ends of the intercepting chambers into
which the stem and mouthpiece would respectively screw or push into or over as
desired.
Drawings 13 and 14 are cross sections of the pipe shewn in elevation in
drawing No. 4.
It will be seen that the main feature of my Invention consists in the two distinct
receptacles for the saliva and nicotine divided from and trapped against one another
in the manner described and shewn so that the Saliva is confined to the mouthpiece
and the nicotine to the stem and bowl of the pipe.
I do not restrict myself to the use of any particular materials in the manufacture of
these pipes, preferring however to use the materials commonly now used in making
pipes Hard wood, Meerchaum, clay &c. for the bowls and Stems, Amber, Vulcanite
Ivory &c. for the mouthpieces and ulcanite, Ivory Horn, Metal &c. for the middle
connecting pieces, using appropriate mountings for strength or ornament in the
ordinary manner where desirable.
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 :-
Firstly-The arrangement and construction in both the mouth-piece and Stem of

page_text: the pipe of a hollow intercepting chamber in conjunction with a double plug or
middle connecting piece with projecting tubes constructed and fitted together
substantially in the manner shewn in the drawings (Nos. 1 to 14 inclusive excepting
only Nos. 8. and 11.) so that each of these intercepting chambers are trapped one
against the other all as herein described and shewn in the before mentioned drawings
annexed hereto.
Secondly-The hollow chamber in the mouth-piece trapped by the modified plug
or connecting middle piece and projecting tube or tubes, such modified plug being
permanently fixed either in the Stem or mouthpiece of the pipe and with or without
the intercepting chamber (d.) all as shewn in drawings Nos. 8 and 9 and as described
herein.
