I, WILLIAM ALEXANDER LYTTLE, of Andover Lodge, Albion Road, Ham-
mersmith, in the County of Middlesex, Gentleman, do hereby declare the
nature of the said Invention for "IMPROVEMENTS CONNECTED WITH CIGARS AND
OTHER TOBACCO-SMOKING APPLIANCES," to be as follows:-
1. I prepare a conical or other shaped tube of paper, tobacco leaf, or other
suitable substance, and fill it with a filtering material, as herein-after described.
Into one end of this tube I insert the "butt" or mouth end of a cigar,
attaching it in that position by gumming, or otherwise securely binding it
previously to its sale; or I prepare the filtering tube so as to be saleable and
portable, as a separate article, attachable to the cigar by the person about to
use it. In the latter case the inner surface of the end of the tube intended to
receive the cigar might be coated with adhesive matter, so that by wetting the
end of the cigar it may adhere on insertion.
2. As a filtering material, I use charcoal powder, cotton wool, flax, hemp,
or any other suitable powdered or fibrous material, or simply a roll or strips
of a suitable kind of cloth or coarse paper. These materials may be used
separately or combined, and may, if desired, be impregnated with perfume
and with chemicals possessing affinity for the empyreumatic impurities of the
tobacco smoke.
3. I do not claim any solid masses, carved or moulded, as filters or

page_text: absorbents, and I do not employ the above-named filtering materials as merely
linings of the tube, but as loosely packed charges, so as to compel the smoke
to come into close proximity with a cousiderable number of absorbing points
or surfaces.
4. When a loose powder is employed, one or both ends of the tube must of
course be covered, plugged, or otherwise secured, so that while the sifting out
of the powder is prevented, free egress may be given to the smoke.
5. These filtering arrangements can also be embraced in the original manu-
facture of the cigar or cigarette, the filtering preparation selected forming one
end of the cigar or cigarette, and being enveloped in the outer leaf forming its
covering.
6. A similar arrangement of filter is also strictly applicable to the pipe,
cigar-holder ("tube") or other receptacle for the combustion of tobacco, the
only material difference being that the filter in the latter cases does not
necessarily require an air-proof envelope or cylinder around it.
7. In the case of the pipe, a perforated metallic or other shield may, if
desired, intervene between the tobacco and the filter to prevent the com-
munication of the fire to the latter when the tobacco has been nearly burned
away.
8. All these applications are reducible to one single principle, which I
claim, viz., the purification of tobacco smoke by exposing it to the action of a
considerable number of absorbent points or surfaces in close proximity.
9. In the word "tobacco" I include all herbaceous preparations which may
be used with or take the place of tobacco.
