PROVISIONAL SPECIFICATION.
Improvements in Tobacco Smoking Pipes.
I CHARLES MILES of 6 Wells Road Totterdown Bristol in the County of
Somerset, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention which is a syphon, condensing, tobacco pipe, has for its object,
"improvements" in tobacco smoking pipes of all kinds; viz., a syphon that shall
prevent saliva, from entering the bowl of pipe, and to collect the nicotine that is
evaporated by the burning tobacco, in a condensed form, the principles of which is
as follows.
I construct a pipe of any desired form or pattern with a fulness on the bowl of
the required shape; extending up the side of said bowl from the stem, and of
sufficient size to carry two bore holes, or smoke channels, leading from the base
of bowl upwards towards the top of said bowl, and of sufficient distance from bore of
bowl to insure the fire from the tobacco, from burning through the second bore
hole, or smoke channel, leads from channel in stem towards the top of pipe bowl;
a communication is then made between the said holes, at the required distance from
said stem, the ends of said holes are stopped by a plug or other suitable means,
forming an air tight communication with the stem and bowl; thus forming a
syphon; the channel leading from the bore of bowl is carried downwards and at an
angle to meet the first bore hole leading to the top of pipe; directly beneath is
formed the usual boss at the bottom of bowl which boss is hollowed out to form a
reservoir for the nicotine that may run down the first bore hole, or smoke channel,
leading from the bowl; the junction of the hole from bowl and first bore hole
would be below the entrance to bowl, thus preventing any oil that may accumulate,
running into the tobacco.
The path of the smoke when drawn from the mouthpiece of pipe is as follows;
The smoke passes down the angular hole from bowl, and up towards the top of
bowl, through the aforesaid communication, down the second channel to the stem,
from thence to the mouth, thus making a syphon which is a trap and condenser for
the nicotine, and effectually preventing the saliva from mixing with the nicotine,
and keeping all moisture flowing from the mouth from entering the bowl of
said pipe.

COMPLETE SPECIFICATION.
Improvements in Tobacco Smoking Pipes.
I CHARLES MILES, of 6 Wells Road Totterdown, Bristol, in the County of
Somerset, Engineer, 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 has for its object improvements, in tobacco smoking pipes, of
all kinds, which may be constructed of wood, meersham, clay, composition or of any
material, where such means can be applied. The principle of which is to carry, or
conduct the smoke from, or near the base of the bowl of pipe, toward the top of
[Price Bd.

page_text: said bowl, & from thence to the stem; thus forming a syphon, in a chamber
provided by an extended boss, or fullness on the bowl, or wall of pipe of sufficient
size, or of any desired form & position on the said bowl.
The path of the smoke as herein before described is obtained by forming the heel
of pipe, of sufficient size to accomodate a close fitting plug, sufficiently long to form
a bridge, or division, in a hole or chamber formed in the said boss, which plug is
flattened on either side the required distance from the top, thereby causing the
smoke to pass up, and over the top of blade, & down to the stem, or I otherwise
bore two holes in said boss, one of which meets the bore of bowl; the other to the
stem I then make a counter bore from top of the boss, of the required depth,
and of sufficient size to cover both holes; which counter bore is partially stopped
by a plug, or other suitable means, allowing a passage from bowl to stem; or
I construct a plug having a small tube attached; which plug is fitted to the heel of
pipe, the said tube extending into the boss, thus forming an annular space in said
.boss, the channel from pipe would lead to the annular space, the bore in stem
would connect the bore in tube, thus the smoke would be syphoned around, and
up the annular space, down through the tube, from thence to the mouth.
Or a thin bridge can be driven into the hole in boss, & a suitable plug fitted to
the heel, and against the said bridge, thus deciding the path of the smoke.
In the syphon I place wool or any absorbant material that shall collect the
nicotine.
In order that my invention may be clearly understood, I will now more fully
describe the same aided by the accompanying drawings.
Figure 1 is a section of pipe, shewing the plug inserted from the heel, &
shewing said plug flattened to form bridge, or syphon. A is the bowl. B. C. D E. is
the path of smoke.
Figure 2; is a plan of same, shewing channels for smoke at C. D.
;
Figure 3 shews the arrangement of tube syphon, the smoke passing around, and
up the sides, down the bore of tube by way of D. E. to the mouth.
Figure 4; is a plan of same.
Figure 6; shews a thin division driven into the chamber in boss. F. F. are the
accessable plugs.
Figure 5; shews a syphon formed by boring two holes, the section of which is as
Figure 6.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
1st. The principle of a syphon, formed on the bowl of pipe, for the purpose of
preventing the saliva, entering the bowl of pipe.
2nd. A system of condensing the nicotine pure, & separate from the saliva; by
means of a syphon, substantially as herein set forth, & with reference to the
accompanying drawings.
