COMPLETE SPECIFICATION.
Improvements in Tobacco Pipes.
I, EDWARD GRIFFETH DELOE, of Knox, in the County of Clarion, and
State of Pennsylvania, United States of America, Photographer, 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 relates to tobacco pipes, the object being to provide an improved
construction of the same, whereby the smoke from the bowl is caused to take a
circuitous route through passages formed in the wall of the pipe before being drawn
into the stem, whereby the advantages of a long stem are secured, while the pipe
itself may be but a short distance from the mouth.
The invention consists in the novel construction hereinafter described and
claimed.
In the accompanying drawing-
Figure 1 is a sectional view of a pipe bowl constructed according to my
invention;
Figure 2 is a plan view of the same, one of the annular rings being removed;
Figure 3 is a side elevation, partly in section.
In the said drawing the reference numeral 1 designates a pipe bowl of any
suitable material, having circumferential grooves at the top and bottom forming
bosses 2 and 3, which are screw threaded to receive the annular ring 4 and disk 5,
respectively, which are correspondingly threaded, the disk 5 being provided with a
central recess in which the boss 3 fits. The bowl is provided with the usual cavity
to receive the tobacco, and is also provided with an aperture 6 in its bottom, which
is closed by the disk 5. This aperture is smaller in diameter than the said cavity,
so that a shoulder 7 is formed upon which rests a wire ganze or perforated metal
plate 8.
The numeral denotes a series of vertical smoke passages formed in the wall of
the bowl, alternately connected together at top and bottom by means of the
horizontal passages 10, whereby one continuous passage is formed. One of these
vertical passages adjoining the boss 12, which receives the pipe stem, is connected
with the interior of the bowl by means of a passage 13, communicating with said
bowl at the center, while the passage adjoining the boss on the opposite side is
connected with the boss by means of a passage 14.
The operation is as follows: When the annular ring and disk are screwed in
place, a continuous passage will be formed, the smoke from the bowl passing
through the passage 13, to the vertical passage upon one side of the boss 12. It
then ascends said passage till it reaches the top, when it will pass through the
top when it will pass through the horizontal passage 10, to the next vertical passage,
through which it will descend till it reaches the bottom thereof, when by the lower
horizontal passage it will pass to the next vertical passage and so on till the last
passage is reached, when it will enter the boss through the passage 14, and from
thence be drawn into the stem. By means of the perforated plates, the tobacco
is prevented from entering the smoke passages and clogging the same and the
space between the said plate and the disk form a nicotine chamber which can be
readily cleaned by receiving the said disk.
The advantages of my invention will be apparent. It secures the advantages
of a long travel for the smoke before reaching the mouth with but a short stem,
and by removing the annular disk the passages can be readily and thoroughly
cleaned.

page_text: Having thus described my invention, what I claim is:
1. A tobacco pipe comprising a bowl having annular grooves at the top and
bottom, vertical passages alternately connected together at top and bottom by
horizontal passages, passages connecting said passages with the bowl and with the
stem, and the annular disks fitting in said grooves, substantially as described.
2. A tobacco pipe comprising a bowl having annular grooves at the top and
bottom, vertical passages alternately connected together at top and bottom by
horizontal passages, passages connecting said passages with the bowl and with the
stem, the annular ring and disk, and the perforated plate located in the bowl,
-substantially as described.
Dated this 24th day of March 1894.
