Improvements in Tobacco Pipes.
We, CHARLES FOURACRE, and HENRY MOORE, both of Failand House, Birch
Street, New Swindon, in the County of Wiltshire, Engineer and Engineers
Assistant respectively 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:—
The improvements in tobacco pipes constituting our invention consists of the
combination of an auxiliary smoke passage composed of some absorbant material,
placed within, but not in touch with, the outer wall of the bowl stem, and of a
number of small holes or passages for air, formed in the said bowl stem, and if
necessary a certain portion of the mouthpiece, by means of which the said absorbant
material is constantly in touch with the atmosphere and thereby kept always cool,
the object of our invention being, that by reason of the coolness of the said
absorbant material forming the smoke passage, the smoke itself becomes cool in
passing therethrough, and such nicotine as would otherwise pass from the bowl to
the mouth of the smoker, or such saliva as would otherwise pass from the mouth to
the tobacco in the bowl, are both arrested and absorbed by the said absorbant
material, thereby economizing the consumption of tobacco and adding to the
enjoyment of the smoker.
In order that our invention may be clearly understood reference is hereinafter
made to the accompanying drawings, in which,
Fig. 1 is an external elevational view of an ordinary pipe provided with our said
improvements
Fig. 2 is a plan or top view of same.
Fig. 3 is a vertical longitudinal section of Fig. 1.
Fig. 4 is a perspective view of the said auxiliary smoke passage composed of
absorbant material.
For the purposes of our invention the bowl of the pipe A and the stem of the
same B, may be of any dimensions, shape or configuration, and may be of wood,
clay or meerschaum, and provided with a mouthpiece C, of any suitable material, in
the usual way, which may either make frictional contact with, or screw into the
stem B as desired. It is usual in pipes of this class for the smoke passage D in B,
and the smoke passage E in C to be of equal diameter throughout, and to meet each
other, or nearly so, at or about the junction of B and C, but according to our
invention we bore, or otherwise provide, that the passage E for a suitable distance
into the bowl end of C, shall be of such diameter as to receive and hold one end of
an internally bored cylinder F (Fig. 4) as shewn in Fig. 3. The stem B is also
bored or otherwise provided with an extended diameter of the passage D, reaching
nearly to the bowl A, the said extended diameter being such, that when the mouth-
piece C, with its cylinder F, is screwed or otherwise connected to B, a pronounced
clearance G exists between the cylinder F and the stem B, as shewn in Fig. 3.
This clearance G is of vital importance for the purposes of our invention as
hereinafter explained.
The stem B is provided with any number of holes or air apertures H, so that
when C and B are connected as at Figs. 1 and 2, the cylinder F may be clearly
seen through the said holes or apertures, and by means of these and the clearance G
the said cylinder is always open to, and receives the cooling influence afforded by,
the surrounding atmosphere. Similar holes H ay if necessary be provided in the
buck end of the mouthpiece C, for the further cooling of F.

page_text: The cylinder F may be produced from soft clay, pummice or other material
capable of freely absorbing moisture, or this may be made of rolled paper, similar
to, and indeed may be, an ordinary squib case, and of such a length, that when C is
placed in position within B, the ends of F abut firmly against the ends of the small
bores D and E, as shewn in Fig. 3, or this may conveniently be one sixteenth of
an inch longer than the space provided therefore in B and C, so as to more firmly
abut against D and E as C is forced into B. Of whatever material the cylinder F
may be made, this would be provided with an internal bore or passage J, as shown
at Fig. 4, which may or may not be larger-in diameter than D and E, and with both
of which J would coincide when placed in position as stated, and shewn in Fig. 3,
thereby forming a smoke passage directly from D to E.
It will therefore be understood that by reason of the absorbant nature of the
cylinder F, this would readily take up any oily or nicotian particles coming from
the bowl A, and any saliva coming from the mouthpiece C, and being always
exposed to the atmosphere, would impart thereto whatever heat it may conduct from
the bowl A, and by reason of the continued coolness of F, the smoke passing there-
through must necessarily be cooled thereby, and when the said cylinder has become
unpleasantly fowl, by removing the mouthpiece C, the same may be cast away
without the need of this being touched by the fingers, and a new cylinder substituted
therefor. Our invention is equally applicable in the manufacture of cigar and
cigarette holders.
We are aware that absorbant tubes of varying lengths, shapes and material have
hitherto been placed between the mouthpiece and the stem of pipes of this class,
for the purpose of absorbing moisture, therefore we do not broadly claim the use of
the cylinder F except in combination with the other improvements constituting our
invention, but.
Having now fully described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is.
1st. In the manufacture of tobacco pipes, cigar and cigarette holders, the com-
bination of an absorbant cylinder F, and the manner of retaining the same in
position so as to be surrounded by a cooling space G, open to the atmosphere by
"the means of air holes or apertures H, substantially as and for the purposes berein
described and shown.
2nd. In the manufacture of tobacco pipes, the employment of a bowl A, stem B
and mouthpiece C, the latter bored to receive and hold one end of an absorbant
cylinder F, having a passage J, the stem B being so formed for the reception of F,
that a clearance G exists between them, open to the atmosphere by the means of
holes H formed in B, and if desired in the mouthpiece C, the whole connected
combined and operating substantially as and for the purposes herein described and
shewn by the accompanying drawings.
