IMPROVEMENTS IN TOBACCO PIPES
Year: 1885

page_text: I, DAVID SCHWAB, of 75 Follerstrasse, Cologne, in the German Empire, Pipe
Manufacturer, do hereby declare the nature of said invention for IMPROVEMENTS
IN TOBACCO PIPES, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement, reference
being had to the accompanying drawings, and to the letters and figures marked
thereon, that is to say:
My Invention has for its object the construction of tobacco pipes in such a
manner as to prevent the nicotine, and other deleterious products of the tobacco,
entering the mouth of the smoker.
For the purpose of my Invention the pipe is so constructed that the bore of the
stem is not, as is usual, in direct communication with the bowl, but terminates in
an inclined passage or channel contrived in the wall of the bowl, and which passage
or channel opens into a chamber formed or fitted beneath the bowl of the pipe.
In this chamber is a second passage, hole, or orifice, which is in communication
with the bowl, and through which the smoke, as drawn from the kindled tobacco,
enters the chamber before passing up and along the inclined passage or channel to
the bore of the stem.
I proceed to describe fully my invention. with reference to the accompanying
drawings, in which,
Fig. 1 is an elevation of a pipe constructed according to my Invention, and
Fig. 2 a longitudinal section thereof.
The arrow in fig. 2, shews the direction of the smoke from the bowl to the stem.
A, is the bowl of the pipe, and B is a chamber, which is formed or fitted beneath
the same.
This chamber is provided with a cup or receiver C, into which the
deleterious products of the tobacco deposit themselves. This cup or receiver may be
retained in place by a screw thread, or by frictional contact, and may be made of
any suitable material. At the bottom of the bowl is a hole a, opening into the
chamber B, and at a short distance from this hole is a passage or channel b, formed
in the wall of the bowl and extending upwards in this wall from the chamber B at
any suitable angle. This passage b, opens into the bore of the stem and forms a
continuation of the same.

page_text: Thus it will be seen that by means of my Invention the smoke is drawn through
the chamber B wherein it deposits its solid products, and at the same time becomes
cooled, and thence it enters the distinct and independent passage or channel b,
where it passes along the bore d of the stem to the mouth of the smoker.
Although I have shewn my Invention as applied to a pipe having a straight
stem, it may be applied, in similar manner, to pipes having bent or curved stems.
Having now described the nature of my Invention and in what manner the
same is to be performed, I wish it to be understood that I do not claim the
chamber beneath the bowl, nor the receiver or cup, taken by themselves, but what
I do claim and desire to secure by Patent is
The construction of tobacco pipes in which the bore of the stem terminates in a
passage or channel contrived in the wall of the bowl and opening into a chamber
beneath and in communication with said bowl substantially as described and as
shewn in the drawings.
