Improvements in the Bowls of Tobacco Pipes.
I, RICHARD HEYD, a subject of the Emperor of Germany, residing at
Lizenhausen near Stöckach, Grand Duchy of Baden, Germany, Manufacturer 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:-
It relates to the bowls of tobacco pipes where the smoke is drawn off laterally.
Hitherto tobacco smoke has been inhaled mostly after suction through the
tobacco itself with the disadvantage that a large portion of the tobacco was not
consumed, a damp and strong crust forming in the pipe and causing the tobacco to
burn down the centre hollowly.
The object of this invention is to render tobacco-smoking dryer, more economical,
and healthier; accomplished by having the smoke drawn not through but out of
the tobacco, and differing from known contrivances (see for example papers in
German Patents Nos. 5119 and 29191) in drawing where the tobacco burns or
beneath it. The tobacco burns hollowly no longer because a better evaporation of
its moisture and a better draught is ensured than has been the case previously,
whilst any residuum is deposited in the form of a powdery crust in the fluelets or
passages wherethrough the smoke is drawn, and whence it can be scraped from
time to time.
The chief feature of this invention is the provision between the tobacco and the
wall of the pipe-head of spaces through and out of which the smoke is drawn, there
being no outlet in the bottom of the interior bowl which holds the tobacco, the
pipe-head consisting of an exterior and interior bowl.
In every case provision is made hereby for an inserted tobacco-holder or interior
bowl easily cleaned, and pierced with holes regularly arranged, to be placed in an
exterior bowl of a special shape, the intervening spaces before mentioned
simultaneously shut off at top and bottom.
In the accompanying drawing, where the same letters denote the same parts,
Figure 1 shows a longitudinal section of a bowl where the spaces between its
wall and the tobacco constitute a spiral.
Figure 2 gives a view of the removable holder or interior bowl appertaining.
Figure 3 shows a section of this bowl at A-B.
Figure 4 shows a longitudinal section through the bowl of a pipe where the
spaces between its wall and the tobacco are in the form of annular grooves which,
as required, can be brought into connection with the stem socket through which
the smoke is drawn downward.
Figure 5 gives a section of the same at A-B.
Figure 6 presents the long section of a pipe bowl formed like that in Figure 4 in
which the stem socket is attached and draws laterally.
Figure 7 gives a view of the pipe with the stem socket cut through at C-D.
In the Figures 1-3 a removable holder or interior bowl is shown which consists
of a thin-walled cone, spiral shaped and perforated with holes in rows, closing the
bowl at the top and having on its circumference a screw-like flat-topped ridging or
flange whose outer extent closes on the internal surfaces of the exterior bowl also.
The floor of this interior bowl is about two of the winding fluelets above its
projecting bottom rims which are set on a stand or shell, shaped like the bottom-of
a champagne bottle, which catches the nicotine but permits the communication of
the spiral spaces with the part here (d) whence the smoke is drawn. For this
object the crown of the bottom of the stand or shell is perforated, while the holes

page_text: in the lowest part of the interior bowl or holder-i.e.—those in the rims which
extend below its bottom, allow the smoke exit.
Differing somewhat, in Figures 4-7 a removable tobacco-holder or interior bowl
is presented which is perforated with various parallel rows of holes. These
holes (61 6363) of semi-circular form correspond with annular furrows or grooves (a¹
a a³), also parallel, in the exterior bowl (a). These parallel grooves in the
exterior bowl (a) can only through a suction-stop (e) be brought, and singly, into
connection with the space yielding the tobacco-smoke (d). This suction-stop (e)
is composed of two small pipes the larger of which, connected with the bowl at the
bottom and by three holes in a vertical line corresponding with the annular
grooves, is open at the top. Into this a smaller pipe (eº), closed at its upper end,
with three holes bored along its length in a spiral line at intervals (e¹ eª e³) corre-
sponding with the annular grooves, is fixed completely air-tight. This latter pipe
when turned the necessary distance and direction serves to shut off or to connect
the rows of holes in the holder or interior bowl. Thus it is made possible that, for
example, the upper row (b) is connected through the hole (e¹) of the smaller
pipe (e) of the suction stop and in consequence with the stem socket (d) into
which all the parts converge downward, while the rest of the connecting holes are
shut off from the annular grooves. Each single one of the pipe-holes (e¹ e² e³) then
occupy a place in a spiral line relatively to the others. All necessary movements
of the suction-stop are made by means of the handle F. g denotes a leathern
casing.
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 :-
A pipe-bowl or pipe-bead consisting of an exterior and interior bowl, the latter
being perforated with holes laterally having a closed bottom, and holding the
tobacco the smoke of which is drawn through such holes from the tobacco to the
outside laterally instead of through the tobacco.
Dated this Sixteenth day of July 1894.
