PROVISIONAL SPECIFICATION.
Improvements in Pipes for Smoking.
I JOSHUA MICHAEL JACOBS of 6 Castle Street, Falcon Square, in the City of
London, Manager, do hereby declare the nature of this invention which has
been communicated to me from abroad by Messrs. W. B. Haas and Co. of
64 Rue d'Hauteville, Paris, France, Pipe Manufacturers to be as follows:-
This invention relates to a special kind of internal fitting for pipes to check the
flow of nicotine and to prevent the saliva from the stem or the mouthpiece getting
to the tobacco in the bowl and wetting it as is usual with most pipes, a circumstance
which tends to make it "draw hard" and the smoke from the tobacco somewhat
rancid and unpleasant to the smoker.
To carry this invention into practice the aperture in the stem is made rather
larger than usual and the neck hole near the top leading to the bowl. Just below
this neck hole a recess is made for the reception of a rod which fits the aperture
centrally said rod being of such a length that its opposite end projects beyond the
part where the mouthpiece is screwed or otherwise secured to the stem there being
a clearance around the projecting end, in the mouthpiece for the free passage of
smoke from the bowl and stem.
Within the stem is a shell of curved formation somewhat like a cartridge shell
and one (the narrow) end fits closely on the rod and abuts against the end of the
aperture, the other or broader end fitting close against the wall of the aperture.
This cartridge like shell has a hole in its shoulder and forms the completion of the
smoke passage there being a clearance between the narrowed portion of the
cartridge like shell and the wall of the stem aperture for the collection of
the nicotine the closed end of the cartridge like shell preventing the passage of
saliva to the bowl.

COMPLETE SPECIFICATION.
Improvements in Pipes for Smoking.
I, JOSHUA MICHAEL JACOBS, of 6 Castle Street, Falcon Square, in the City
of London, Manager, do hereby declare the nature of this invention, which has
been communicated to me from abroad by Messrs. W. B. Haas and Co. of
64 Rue d'Hauteville, Paris, France, Pipe Manufacturers, and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement :-
This invention relates to a special kind of internal fitting for pipes to check
the flow of nicotine, and prevent the saliva from the stem, or the mouthpiece
getting to the tobacco in the bowl and wetting it, as is usual with most pipes, a
circumstance which tends to make a "draw hard," and the smoke from the tobacco
somewhat rancid and unpleasant to the smoker.
To carry this invention into practice, and as represented in the annexed drawings,
Figure 1 of which is a section of a complete pipe, Figure 2 a section of bowl only,
and Figure 3 part section of mouthpiece end, the aperture in the bowl stem A is
made rather larger than usual, and the neck hole B leading to the bowl is near the
top. Just below this neck hole, a recess is made for the reception of a rod C which
1

page_text: fits the aperture centrally, said rod C being of such a length that its opposite end
projects beyond the part where the mouthpiece D is screwed, or otherwise secured
to the stem, there being a clearance around the projecting end in the mouthpiece
for the free passage of smoke from the bowl E and stem A. Within the stem A
is a shell F of curved formation somewhat like a cartridge shell, and one, (the
narrow) end G fits closely on the rod C and abuts against the end of the aperture,
the other or broader end fitting close against the wall of the aperture in A.
This cartridge like shell has a hole H in its shoulder, and forms the completion of
the smoke passage, there being a clearance between the narrowed portion of the
cartridge like shell and the wall of the stem aperture for the collection of the
nicotine, the closed end of the cartridge like shell preventing the passage of
saliva to the bowl.
I make the fixture of the mouthpiece D to the stem A by an intersecting piece I,
and this preferably screw threaded, as shown, but it can be made to fit tight by a
pushing on action.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is -
―:
The improvements in pipes for smoking, as herein set forth, and consisting of a
cartridge like shell F with hole H, .central rod C within enlarged aperture in
stem A arranged substantially as represented on the annexed drawings.
