Improvements in Tobacco-pipes and Cigar or Cigarette Holders.
I, GENARO TAGELL Y VENTURA, of 745, Calle Tucuman, Buenos Aires, in the
Argentine Republic, Merchant, 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 an improved method of constructing the stems of tobacco-
pipes, and holders for cigars and cigarettes, whereby the smoke becomes cooled
and purified to a considerable extent before reaching the mouth of the smoker;
thereby increasing its agreeable qualities and, at the same time, preventing many
of the well known injurious effects of tobacco smoke upon the human system with-
out affecting the outward appearance and convenient form and size of such pipes
or holders.
In addition to carbonic oxide, hydro-sulphuric and hydrocyanic acids and pyridic
bases, tobacco smoke contains a highly poisonous alkaloid-collidine; all of which
constituent agents exercise their most powerful action while still preserving the
heat which produced them. For this reason, the devices which have been proposed
for remedying the evil effects by preventing the absorption of nicotine into the
system, and which consist in effecting the deposit of that substance in receptacles,
sponges, through which the smoke is made to pass, and the like, have failed to fully
accomplish their object, in so far that they permit the smoke to be drawn into the
mouth in the heated state, which constitutes its most injurious feature.
It has been found that the only adequate remedy lay in causing the smoke to
traverse an extended or lengthened passage, but this has usually involved the
employment of a pipe stem or holder of inconvenient length.
According to my invention the smoke passage may be almost quadruply
lengthened; the dimensions of the stem of the pipe, or cigar or cigarette-holder
being of ordinary size, form and material.
In the accompanying drawings, Fig. 1 is a longitudinal section of a pipe con-
structed according to my improved method. Fig. 2 is a similar view of an
alternative construction. Figs. 3 and 4 are longitudinal sections of cigar- or
cigarette-holders embodying my invention; Fig. 4 being an elevation of the tube
employed in Fig. 3. Fig. 5 is a rod or pusher for employment in ejecting the
spirally-grooved cylinder pertaining to the pipe or holder shown in Figs. 1 and 3
In carrying out my invention, the bore of the stem a is slightly enlarged up to,
say, within 3 or 1½ inch of the tip, or up to, or nearly up to, the mouth-piece al
and into such enlarged bore or tube, is inserted a spirally-grooved cylinder b of
wood or any other suitable material. The surface of this spiral groove which
preferably forms a semicircle in its cross section, is closed by the inner surface
of the bore of the stem or holder, against which the ridges of the said grooved
cylinder fit closely. The spiral groove thus forms a tube several times longer than
the length of the cylinder itself. The smoke in traversing this lengthened passage
not only becomes cooled, but a large proportion of the nicotine contained therein
becomes deposited on, and absorbed by, the inner surface of said passage.

page_text: In the form of pipe illustrated in Fig. 1, the spirally-grooved cylinder b is shown
loose, that is to say, unattached to the mouth-piece. In order to remove the
cylinder, the screw stud c is removed and the cylinder pushed out by means of the
rod d (Fig. 5) the latter being introduced through the bore of the mouth-piece a¹.
The cylinder may thus be readily cleaned and replaced.
The grooved cylinder & may be formed as a part or extension of the mouth-
piece a, as shown in Fig. 2, in which case the cylinder is removed along with the
mouth-piece after unscrewing the latter.
In Fig. 3I have illustrated a cigar- or cigarette-holder in which a loose cylinder b
is employed similar to that shown in the pipe, Fig. 1, while in Fig. 4 the holder is
shown as composed of two pieces-the outer or tubular portion and the spirally
grooved cylinder b whereof a portion forms the mouth-piece and which is intro-
duced into the hollow cylinder. This latter form renders the cleaning of
the holder simple and easy, it being only requisite to withdraw the mouth-piece,
whereupon the spirally grooved cylinder is also withdrawn; while the unsmoked
butts or stubs may be ejected, without contact with the fingers, by simply pushing
in the mouth-piece.
Although I have illustrated my invention as applied by way of example to pipes
and holders having straight stems it will be understood that other forms of stems
may be used and that any suitable material may be employed in its construction.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I claim:
1. For employment in pipes or cigar- or cigarette-holders, a removeable spirally-
grooved cylinder or plug, whereof the groove, in conjunction with the inner surface
of the bore of the pipe-stem or holder, forms an elongated passage for the smoke
substantially as described.
2. In a tobacco-pipe or cigar- or cigarette-holder, the combination, with the
stem or tubular portion a of a spirally grooved cylinder b, substantially as set forth.
