COMPLETE SPECIFICATION
Improvements in Tobacco Pipes and Cigar Holders.
1, WILLIAM SALE HANNAFORD, of 312, North Marengo Avenue, l'asadena, in the
County of Los Angeles, and State of California, United States of America, Inven-
tor, do hereby declare the nature of my invention, and in what manner the same
1s to be performed, to be particularly described and ascertained in and by the
following statement:-
The object of the invention is to provide a new and improved tobacco pipe,
which is simple and durable in construction, and auanged to prevent the nicotine
and other unhealthy substances from passing to the mouthpiece, to prevent
clogging, and to purify and cool the smoke on its passage through the pipe, and
thus rende smoking pleasant and innocuous.
The invention consists of novel features and parts and combinations of the same,
as will be fully described hereinafter and then pointed out in the claims.
Reference is to be had to the accompanying diawings forming a part of this
specification, in which similar characters of reference indicate corresponding
paits in all the figures.
Figure 1 is a sectional side elevation of the improvement,
Figure 2 18 a sectional plan view of the same, on the line 2-2 of Figure 1;
Figure 3 is a side elevation of the draft plug; and
Figure 4 is a plan view of the cover for the spiral passage
The improved tobacco pipe illustrated in Figures 1 and 2, is provided with a
bowl A, adapted to be screwed or otherwise secured to the enlarged end or sub-
bowl B of the stem B, having at its forward end the usual mouthpiece. (Not
shown).
In the under side of the bottom of the bowl A is formed a recess A¹, closed by a
cover C, of blotting paper or other suitable material, and held in place in the sub-
bowl B over a chamber B by the lower end of the bowl A The cover C closes
the top of a convolutional spiral passage D, arranged in the upper portion of the
chamber B³, and connected at its middle D¹ with openings E, formed in the wall
of a draft plug E, mounted to turn centrally in the bottoms of the bowl A and
sub-bowl B as well as in the cover C, as plainly illustrated in Figure 1, the lower
outer end of the said plug being formed with a suitable knob or handle ³, adapted
to be taken hold of by the operator, for either turning the plug in its bearings
or for withdrawing it for cleaning purposes, in case the draft passage is clogged by
ashes or tobacco
The plug E is preferably made in sections, of which the upper section is of
metal and extends into the bowl A above the bottom thereof; and side openings Es
lead from this upper end to a central bore E, connected by the openings El with
the middle of the spiral passage D, as above stated. The lower section of the plug
is preferably made of solid vulcanite or hard rubber
By the arrangement described, communication is established between the interior
of the bowl A and the middle D¹ of the spiral passage D, to allow the smoke to
pass from the bowl through the plug into the said spiral passage, and in case an

page_text: obstruction clogs the plug, the operator turns the plug and brings the openings E³
to different places in the bowl, or if necessary he removes the plug entirely and
blows the obstruction out of the plug should such obstruction have lodged in the
openings E or E', or the bore E.
The walls of the spiral passage D are disposed vertically, as is plainly indicated
in Figure 1, and the outer end D of the spiral passage D connects with the inner
end B³ of the bore B' in the stem B, said end B³ being inclined downwardly and
forwardly, as shown in Figure 1 The under side of the spiral passage D reste
on an absorbing pad F, made of a suitable absorbent material placed in the bottom
of the chamber B below the connection between the outer end of the spiral
passage D and the end B³.
It will be seen that by the arrangement described, the smoke from the tobacco
burned in the bowl A is drawn through the draft plug E into the centre or begin-
ning D of the spiral passage D through which the smoke passes, to finally pass
through the end D into the bore of the stem B and the mouth of the smokei
The smoke, during its travel through the spiral passage D, deposits nicotine and
other impurities upon the absorbing material F, forming the bottom of said
passage and contained in the chamber B It will further be seen that by arranging
the passage D spirally, a long path for the smoke is obtained in a comparatively
small space, so that the smoke becomes cooled and purified before reaching the
smoker's mouth
By unscrewing the bowl A the cover C and the absorbing material F may be
renewed from time to time, so as to keep the pipe always in a fresh condition.
It is evident that the arrangement may be applied to a cigar-holder between the
mouthpiece and the tap, to prevent the nicotine from passing to the smoker's
mouth, and to cool the smoke and purify the same on its passage from the tip to
the mouthpiece.
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. A tobacco pipe provided with a draft plug, and a convolutional spiral passage
connected at one end with the bowl and at the other end with the pipe stem, to
cause the smoke to pass through said plug and spual passage on its way from the
bowl to the stem, to cool and purify the smoke, substantially as shown and
described.
2. A tobacco pipe provided with a draft plug, and a convolutional spiral passage
having its wall disposed vertically and connected at its centre with the said draft
plug opening into the bowl, the outer end of the passage being connected with the
pipe stem, to cause the smoke to pass through the passage on its way from the
bowl to the stem, to cool and purify the smoke
3 A tobacco pipe provided with a draft plug, a convolutional spiral passage
having its wall disposed vertically and connected at its centre with the said diaft
plug opening into the bowl, the outer end of the passage being connected with the
pipe stem, to cause the smoke to pass through the passage on its way from the
bowl to the stem, to cool and purify the same, and an absorbent material over which
the smoke passes during its travel through the spiral passage, substantially as
shown and described
4 A tobacco pipe comprising a bowl, a stem formed with a chamber and adapted
to receive the said bowl, a draft plug mounted to tuin in said bowl and chamber,
a convolutional spiral passage arranged in said chamber, and having its wall
disposed vertically, said passage being covered at the top and bottom, the centre
of the passage being connected with said draft plug and the outer end of the
passage being connected with an inclined end of the bore of said pipe stem, sub-
stantially as shown and described.
5. A tobacco pipe comprising a bowl, a stem formed with a chamber and adapted

page_text: to receive the said bowl, a draft plug mounted to turn in said bowl, and chamber,
and a convolutional spiral passage arranged in said chamber, and having its wall
disposed vertically, said passage being covered at the top and bottom, the centie
of the passage beng connected with said draft plug and the outer end of the passage
being connected with an inclined end of the bore of said pipe stem, and an absorbent
material in the bottom of said chamber, and forming the bottom for the said
passage, substantially as shown and described.
6 A tobacco pipe comprising a bowl, a stem formed with a chamber and adapted
to receive the said bowl, a convolutional passage arranged in the said chamber and
having its wall disposed vertically, the centre of the passage being connected with
the outlet of the bowl, and the outer end of the passage being connected with an
inclined end of the bore of the said pipe stem, a cover placed on the open top of
the said passage, a draft plug having a central aperture leading to the centre of the
spiral passage, to conduct the smoke from the bowl to the centre of the passage,
and an absorbent material forming the bottom for the spiral passage, substantially
as shown and described
7. A tobacco pipe comprising a stem formed with a chamber, a bowl removably
connected with the said stem at the said chamber, a draft plug formed with a
passage leading to the inside of the bowl, a cover over the said chamber, a convolu-
tional spiral passage arranged in the said chamber directly under the said cover,
and connected at its middle with the plug passage and at its outor end with the
bore of the pipe stem, and an absorbing material held in the bottom of the chamber
and forming the bottom for the spual passage, substantially as shown and described.
