Improved Smoke Filter for Tobacco Pipes, Cigar, Holders and the like.
I, PETER DAVIES, of 25, Salisbury Street, Runcorn, in the County of Chester,
do hereby declare the nature of this invention, to be as follows:-
:
My invention relates to an improved smoke filter for tobacco pipes, cigar and
cigarette holders. This filter has the advantage of preserving the free draught
through the pipe or the like whilst at the same time condensing and collecting
any deleterious moisture or solids, and thus tending to economy and improve-
ment of the smoking qualities of the pipe and the like.
I may construct my filter in various manners. One method thereof is to take
a suitable quantity of very thin narrow shavings of wood such as pine, cedar,
eucalyptus or other wood preferably supplied loose for the manipulation of the
user, on they may be prepared ready in the form of a porous plug. This plug
whether made by the user at the time of use or previously prepared may have
a core of charged shavings or the like, and I prefer to impregnate the whole
with essence of tea or coffee or with perfumes if desired. I do not, however,
bind myself to this as the filter may equally well be used without such addition.
The advantage of this smoke filter is principally in preventing the tobacco at
the bottom of the bowl or the end of the cigar or cigarette from becoming soft
and limp through the absorption of moisture and other products given off
during the combustion of the tobacco. The moisture and the like tends to cause
the lower end of the tobacco to swell and become foul, and consequently to be
so compacted together as to more or less stop the draught. Further, portions
of the tobacco are liable to pass into the tube and to reach the mouth of the
smoker.
By my invention a suitable layer of material which does not become soft and
limp like tobacco under such conditions, is placed between the burning tobacco
and the draught tube. A free draught is thus secured and preserved and a
large surface is presented for the combustion products to pass through. Con-
sequently it enables the charge of tobacco to be completely smoked out without
discomfort, thus effecting a saving on each pipe-full of tobacco consumed, inas-
much as there is no residue of unconsumed tobacco to be thrown away. In this
manner the improved smoke filter is an efficient auxiliary appliance for tobacco
pipes and cigar or cigarette holders, and renders them capable of being more
agreeably smoked than with the imperfect constructions at present made use of.

the same is to be performed to be particularly described and ascertained in and
by the following statement: -

terious moisture or solids, and thus tending to economy and improvement of
the smoking qualities of the pipe and the like.
I may construct my filter in various manners. One method thereof is to take
a suitable quantity of very thin narrow shavings of wood such as pine, cedar,
cucalyptus or other wood preferably supplied loose for the manipulation of the
user, or they may be prepared ready in the form of a porous plug. This plug,
whether made by the user at the time of use or previously prepared may have
a core of charred shavings or the like, and I prefer to impregnate the whole
with essence of tea or coffee or with perfumes if desired. I do not, however,
bind myself to this as the filter may equally well be used without such addition.
The advantage of this smoke filter is principally in preventing the tobacco at
the bottom of the bowl or the end of the cigar or cigarette from becoming soft

the lower end of the tobacco to swell and become foul, and consequently to be

manner the improved smoke filter is an efficient auxiliary appliance for tobacco
pipes and cigar or cigarette holders, and renders them capable of being more
agreeably smoked than with the imperfect constructions at present made use of.
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
1. The improved smoke filtering and moisture absorbing tobacco pipe, cigarette,
or cigar holder plug, substantially as described.
2. In a smoke filter of the kind set forth, the use of essence of tea, coffee or
other product, or of perfumes, substantially as and for the purpose described.
