Improved Plugs or Filters for Tobacco Pipes, Cigar or Cigarette
Holders, and Cigars or Cigarettes and the like.
JOHN LYALL THOM, Twenty-four, Bank Street, Hillhead, Glasgow, Scotland,
Inventor, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to improved plugs or filters for use in or with tobacco
pipes, stems and mouthpieces thereof, cigars and cigarettes and holders thereof
and the like. The said plug or filter consists of an involuted strip, slip, fold
or leaf of any suitable substance, but I prefer to make it of an absorbing material
such as absorptive or blotting paper. The shape, length, breadth, consistency
and thickness of the strip, slip, fold or leaf are regulated & modified to suit its
ends, uses and purposes, and it is so involuted as to leave an interstice or small
space between each of the involutions or folds and thus permit of its whole
surface or surfaces being exposed and utilised as an absorbing, filtering and
intercepting medium or agency. Whether the said plug or filter is placed in
the bottom of the bowl of a tobacco pipe, or in or on the channel stem or
mouthpiece, or at or in the mouthend of a cigar or cigarette, or in or on the
holders thereof and the like, it is so placed that the smoke or draught, passing
between the mouth of the smoker and the substance smoked, percolates or passes
between or through the involutions or through the interstices or small spaces.
The said plug or filter has the advantage of being extremely light and cheap;
and its objects or purposes are to facilitate combustion, free draught and cool
smoking; to absorb and intercept moisture, aqueous vapour, oils, saliva and
what is commonly called nicotine; to prevent fouling by intercepting dust ash
or objectionable matter; to keep clean the channel or passages between the
mouth of the smoker and the substance smoked; and to prevent waste by allow-
ing tobacco or the like to be smoked dry to the end.

Improved Plugs or Filters for Tobacco Pipes, Cigar or Cigarette
Holders, and Cigars or Cigarettes and the like.
JOHN LYALL THOM, Twenty-four, Bank Street, Hillhead, Glasgow, Scotland,
Inventor, 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:-
This invention relates to improved plugs or filters for use in or with tobacco
pipes, stems and mouthpieces thereof, cigars and cigarettes and holders thereof

page_text: and the like. The said plug or filter consists of an involuted strip, slip, fold
or leaf of any suitable substance, but I prefer to make it of an absorbing material
such as absorptive or blotting paper. The shape, length, breadth consistency and
thickness of the strip, slip, fold or leaf are regulated and modified to suit its
ends uses and purposes, and it is so involuted as to leave an interstice or small
space between each of the involutions or folds and thus permit of it's whole
surface or surfaces being exposed and utilised as an absorbing, filtering and
intercepting medium or agency. Whether the said plug or filter is placed in
the bottom of the bowl of a tobacco pipe or in or on the channel, stem or mouth-
piece thereof, or at or in the mouthend of a cigar or cigarette or in or on the
holders thereof and the like, it is so placed that the smoke or draught passing
between the mouth of the smoker and the substance smoked, percolates or passes
between or through the involutions or through the interstices or small spaces
herein before mentioned. (First). With reference to the making or manufactur-
ing of the said plug or filter for cigars, cigarettes, holders thereof, mouth-
pieces and the like, the absorbing substance or material (preferably absorptive
or blotting paper) of which it is made may be cut and then rolled or involuted,
or it may be rolled or involuted and then cut by hand or by machinery or by both
care being taken that no distinct hole or opening is left in the centre other than
the interstice or small space between each of the involutions or folds. In a
cigar and the like it is inserted into a hole or recess at the mouthend as shown
in Fig. 1, which is a section through a cigar representing the plug or filter A
in position; in a cigarette and the like it is inserted in the wrapper at the
mouthend as shown in Fig. 2, which is a section through a cigarette showing
the plug or filter B in position; and in a holder or mouthpiece and the like
it may be inserted in either end as shown in 1 and 2 of Fig. 3, which are
respectively sections through a holder and a mouthpiece showing the plug
or filter C and D in position all of the accompanying drawings. After the inser-
tion it will by its own natural expansion retain its hold or position; and when
properly adjusted it presents a very compact appearance while at the same time
it provides for perfect draught which can be simply and effectively regulated
according to taste by applying the movement for either rolling up or rolling
down between the finger and thumb or otherwise. I have found it advan-
tageous in these cases to have the said plug or filter tightly rolled or involuted
before insertion so that after insertion complete adjustment may take place by
it's own natural tendency to expand; and (Second). With reference to the
making or manufacturing of the said plug or filter for use in the bottom of the
bowl of a tobacco pipe and the like the absorbing substance or material (pre-
ferably absorptive or blotting paper) of which it is made may be cut and then
rolled or involuted or it may be rolled or involuted and then cut by hand or by
machinery or by both care being taken that no distinct hole or opening is left
in the centre other than the interstice or small space between each of the involu-
tions or folds. After being thus involuted and cut or cut and involuted it is
allowed to expand naturally when it should be of such size as to permit of its
being easily dropped into the bottom of the bowl of a pipe. I have found it
advantageous in this case to roll or involute it very tightly before allowing it to
expand naturally as aforesaid. If desired it can be fitted into the bottom of the
bowl of a tobacco pipe almost as compactly as it is inserted into the wrapper
at the mouthend of a cigarette but this application in a pipe is not so handy
for removing and renewing purposes. Fig. 4 of the accompanying drawings
shows a section through a pipe representing the plug or filter E in position
in the bowl of a pipe. The said plug or filter has the advantage of being
extremely light and cheap, and its objects or purposes are inter alia to facilitate
combustion, free draught, and cool smoking to absorb and intercept moisture
aqueous vapour, oils, saliva and what is commonly called nicotine; to prevent
fouling by intercepting dust, ash, soot or objectionable matter; to keep clean
the channel or passages between the mouth of the smoker and the substance

page_text: smoked to prevent waste by allowing tobacco and the like to be smoked dry
to the end; to prevent colouring or fouling of the lips, teeth and mouth; to
render inhaled smoke less harmful; to prevent the lips teeth and tongue coming
into immediate contact with the tobacco in cigarettes and the like; to afford a
pleasant and reliable hold for lips or teeth in cigarettes and the like; to regulate
the draught i.e. to render a cigarette or cigar and the like easy or less easy
to pull or draw according to taste; to prevent the prevalent grievance of little
bits or particles of tobacco reaching the mouth from a cigarette or cigar, or
holder thereof or pipe and the like; and to lessen expectoration.
In pipe
smoking one of the said plugs or filters may be used for several smokes, or one
may be used for each smoke it being exceedingly cheap and easily removed
and renewed without soiling the fingers.
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:-
-
First. An improved plug or filter of an absorbing substance or material for
insertion in the mouthend of cigars and the like substantially as and for the
purposes hereinbefore described and set forth.
Second. An improved plug or filter of an absorbing substance or material
for insertion in the wrapper at the mouthend of a cigarette and the like sub-
stantially as and for the purposes hereinbefore described and set forth.
Third. An improved plug or filter of an absorbing substance or material
for insertion in cigar and cigarette holders and the like substantially as and for
the purposes herein before described and set forth.
Fourth. An improved plug or filter of an absorbing substance or material
for use in smoke channels and mouthpieces of tobacco pipes and the like sub-
stantially as and for the purposes hereinbefore described and set forth.
Fifth. An improved plug or filter of an absorbing substance or material for
the bottom of bowls of tobacco pipes and the like substantially as and for the
purposes herein before described and set forth.
