Complete Specification Left, 22nd Feb., 1900--Accepted, 19th May, 1900
GEORGE HOWE, Colliery Agent, 26, Grosvenor Road, Wrexham, Denbighshire,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to effect a more complete combustion of tobacco
in tobacco pipes.
.
In ordinary tobacco pipes the air during the process of smoking is admitted
directly to the burning tobacco through the open bowl of the pipe, and as a rule,
a core or plug of unconsumed tobacco generally damp and foul is left in or near
the bottom.
To obviate this I cause a hole or a number of holes to be bored vertically through
the rim or preferably near the rim of the pipe to a point or points about on a
level with the stem of the pipe.
Several holes may be bored vertically or at an angle but all leading to the
inside of the bowl of the pipe preferably to a point about on a level with the stem
of its base.
The pipe is filled with tobacco and lighted in the ordinary way and as the smoke
passes through the tobacco the air admitted through the vertical hole or holes
passes through or around the bottom portion of the tobacco in the pipe and keeps
it dry and sweet enabling a more complete combustion of the tobacco to take
place.

I, GEORGE HOWE, of 26, Grosvenor Road, Wrexham, in the County of Denbigh,
Colliery Agent, 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 object of this invention is to effect a more complete combustion of tobacco
in tobacco pipes.
.
The invention will be understood from the following description, reference
being had to the accompanying drawings, in which-
Figure 1 is a sectional view of a tobacco pipe constructed in accordance with
my invention.
Figure 2 a plan.
In ordinary tobacco pipes, the air during the process of smoking is admitted

page_text: direct to the burning tobacco through the open bowl of the pipe, and as a rule
a core or plug of unconsumed tobacco, generally damp and foul is left in or near
the bottom.
To obviate this, I cause a hole or holes A to be bored vertically through the rim
or sides of the bowl B from the top to a point or points about on a level with
the stem of the pipe C. Any suitable number of holes may be thus bored
vertically or at an angle, but all leading to the inside of the bowl of the pipe,
preferably to a point about on a level with the stem.
In use, the pipe is filled with tobacco and lighted in the ordinary way, and as
the smoke is drawn through the tobacco by suction of the smoker in smoking,
the air is likewise drawn through the vertical hole or holes A, direct to the bottom
portion of the tobacco in the bowl, thus supplying thereto fresh air for its combus-
tion. By this means the pipe is kept dry, sweet and cool, while a more complete
combustion of the tobacco is enabled to take place. It reduces the accumulation
of saliva and nicotine in the stem and bowl, and consequently the pipe does
not require such frequent cleaning as hitherto. The bowl, may have an inside
lining of pipe clay or meerschaum D if desired, between which and the bowl the.
air holes or passages pass.
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. The improvement in tobacco pipes, which consists in forming the bowl with
one or more small holes or passages leading from the top of the bowl to the
inside thereof, near the bottom, through which air is drawn by suction during
the operation of smoking, whereby the tobacco at the bottom of the bowl is
supplied with the necessary air to effect more complete combustion, substantially
as described.
2. A tobacco pipe having air holes in the bowl arranged and operating sub-
stantially as herein before described with reference to and shown in the drawings
annexed.
