We, JOHANN JACOB MÜLLENBACH, WILHELM JACOB THEWALD, CARL JACOB
THEWALD, and JACOB VICTOR MÜLLENBACH, all of Höhr near Coblenz, in the Empire
of Germany, trading as Müllenbach and Thewald, Pipe Manufacturers 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 :-
Our said invention is illustrated by the accompanying sheet of drawings, wherein
Figure 1 is an external view and Figure 2 a longitudinal section of a tobacco pipe
constructed according to our invention. Figure 3 is a separate view of the internal
tube or trough, Figure 4 is a similar view of the mouthpiece and Figure 5 is a section
of the bowl with the mouthpiece and trough removed.
The same letters of reference denote the same parts throughout the figures.
A is the bowl of the pipe and B the mouthpiece. The latter may be made of horu,
vulcanite, amber or other suitable material. The part B₁ of the said mouthpiece fits
tightly into the stem A.
The said stem has a bore of large diameter and the aperture connecting the bottom
of the bowl with the said bore is also of large size. A tube or trough C of metal,
vulcanite or other suitable material, having a closed end C₁, fits on the part B' of the
mouthpiece by means of a bayonet-joint, formed of the right angled slot C³ in the
open end of the tube and the projection B³ on B'. The part B' of the mouthpiece is
prolonged and enters the tube C as shewn. Small holes C³ are provided in the upper
side of the said tube.
A shield or projecting piece D, provided with slots or perforations, as shewn, is
affixed on the end of the tube C, and when the said tube and mouthpiece are inserted
in place, the said piece D forms the bottom of the bowl A.
The action of the apparatus is substantially as follows: The smoke and condensed
moisture from the tobacco pass through the apertures in D, and the said moisture is
caught in the stem A', being unable to enter the tube C or the mouthpiece. Sufficient
annular space is left between the tube C and bore of the stem A¹ for the smoke to
pass through the holes C³ and the smoke being coold by contact with the said tube any

page_text: uncondensed moisture still remaining in the smoke will be deposited therein and the
smoke will thus pass cool and dry down the mouthpiece B to the mouth of the smoker.
It will clearly be seen that the condensed moisture caught either in the stem A¹ or
tube C cannot gain access to the mouthpiece and is therefore unable to reach the
mouth, while the pipe can be instantly taken apart and readily cleaned when
necessary.
In carrying out our invention in practice we wish it to be understood that, provided
the essential principles of the invention are retained, we do not necessarily confine
ourselves to the exact forms or proportions of the various parts as shown in the
accompanying drawings.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is :
The construction of a pipe, for smoking tobacco, in the manner and for the purposes
substantially as herein set forth
