page_text: I, ERNST TRIELOFF of 35 Orleans Strasse, Cassel in the Empire of Germany,
Commercial Agent, 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 :-
The object of my Invention is the construction of smoking pipes, cigar holders, or
cigarette tubes, in such a manner that the smoke which is drawn into the mouth, is
dry and free from moisture or deleterious essential oils.
In carrying out the device or contrivance according to my Invention, I provide a
plug or cartridge of common sponge which is inserted within a suitable recess formed
in the stem of the pipe, or in the cigar holder or cigarette tube, so that all smoke
drawn from the bowl of the pipe or burning tobacco or other substance being smoked
in the cigar or cigarette must pass through said plug or cartridge of sponge which
latter absorbs all moisture or oil.
In order that my Invention may be the better understood, I have appended the
accompanying sheet of drawings, in which Figure 1 represents a sectional elevation
of a short pipe shewing the sponge plug or cartridge in position; Figure 2 cross-
sections of same on lines x, y and r¹, y'; Figure 3 is a sectional elevation of a cigar
or cigarette tube; Figure 4 a cross-section of same, and Figures 5 and 6 represent a
sectional elevational and cross-section respectively of the lower part of a long tobacco
pipe according to my Invention.
Referring to Figures 1 and 2,.the head or bowl of the pipe is shewn at a ;
b being
the stem which is recessed at c as shewn, for the reception of the sponge plug or
cartridge d above referred to; a suitable connection with the howl being made by a
screw thread or equivalent means. As represented in the drawing, the sponge plug
is above the screw connection, but this arrangement may however be reversed and the
screw thread be formed and connected above the sponge plug aforesaid.
In Figures 3 and 4 the sponge plug or cartridge d is shewn within the tube f.

page_text: Referring to Figure 5 and 6, the recess is formed within an extension of the lower
part of the stem of the pipe g into which fits the stem tube i. Below said stem tube
is inserted the sponge plug d, h being the bowl of the pipe.
I
The plugs or cartridges which I employ are cut from ordinary sponge when in the
humid state and said plugs or cartridges will then be of slightly increased diameter
relatively to that of the cavity into which they are to be inserted, so that after
becoming dry, same may be easily introduced into said cavity and readily become
expanded or distended by the moisture absorbed from the tobacco or other substance
being smoked.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
:-
1st. For smoking pipes and cigar or cigarette tubes the use of cartridges or plugs of
sponge substantially as herein set forth.
2nd. Preparing the plugs or cartridges referred to in the preceding claim by
cutting out and forming them from moist sponge, so as at the time of insertion into
the containing recess of the pipe, or in the cigar or cigarette tube, the diameter of
said plugs or cartridges shall slightly exceed that of the cavity into which they are
introduced.
