Improvements in Tobacco Pipes.
I, WILLIAM HENRY HUMPHREYS, of 28, Queen's Road, Liverpool, Manager,
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 :-
This invention relates to an improvement in connection with tobacco pipes, and
has for its object to provide a simple arrangement by means of which the smoking
may be rendered more pleasant.
In carrying out my invention, I employ a small metal tube fitted in the bowl and
placed vertically at the back. This tube extends through the wall of the bowl
from the top to the passage in the stem.
The extremity of this tube projects about half way into the end of the bore
which does not open directly into the bowl.
The tube is formed with two small perforations placed at opposite sides and two
short passages in the wall serve to communicate with the cavity of the bowl. One
of these passages is placed at about the middle and the other at the lower end, the
latter extending preferably at an angle.
The ends of these passages can be made to register with the perforations in the
tube, only one of the passages being employed at one time as the holes are at
opposite sides of the tube.
By this arrangement the smoke is drawn from about the middle of the bowl
instead of having to pass through the tobacco at the bottom of the bowl.
When the tobacco has been partly burnt, the smoke is drawn through the lower
passage.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings in which
Fig. 1 is a section of a pipe with my device fitted in position and
Fig. 2 is an elevation of the metal tube employed.
A. is the bowl of the pipe, having the stem B made in one with it in the usual
manner. The bore bis preferably made somewhat wider than in the ordinary
pipe and is stopped before it reaches the chamber of the bowl. The wall of
the bowl is formed with a vertical perforation extending from its top to meet the
bore b.
In this perforation the tube C is placed, the extremity projecting into the bore
for a short distance. The tube C is formed with the upper and lower perforations o
and placed at opposite sides and in the wall of the bowl corresponding
perforations or passages a and a¹ are made.
In the position shown in Fig. 1 the upper perforation is in operation so that the
smoke is drawn from the upper part of the tobacco through the tube C and thence
into the bore. On turning the tube from the top through a half circle the other
perforation will come into use and the smoke will be drawn from the bottom of the
bowl.
Owing to their being no direct communication between the bowl and bore,
moisture passing from the mouth into the bore will not be able to reach the
tobacco, thus ensuring it being kept dry.
Having
now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.-
(1.) An improved tobacco nine having a vertical passage in the wall of the

page_text: bowl, and a tube inserted therein extending into the bore, two perforations in the
said tube and corresponding passages in the bowl registering with the perforations,
substantially as described and for the purposes specified.
(2.) The improved tobacco pipe having a vertical passage in its bowl, a tube in
the said passage projecting into the bore, two perforations in the said tube placed
at opposite sides, and two passages in the bowl adapted to register with the
perforations, substantially as described and shown in the accompanying drawings
and for the purposes specified.
Dated this 4th day of February 1896.
