Improvements in Tobacco Pipes and Cigar and Cigarette
Holders.
I DAVID GEORGE HOEY, of Commercial Bank Buildings, 8 Gordon Street,
Glasgow, Lanarkshire, Ventilating Engineer, 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 has for its object to secure in tobacco pipes and cigar and cigarette
holders, the efficient elimination of the nicotine and other deleterious and oily
ingredients from the tobacco smoke, before it is inspired by the smoker.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1. illustrates, in longitudinal section, and figs. 2. and, 3. in part section,
different methods of making tobacco pipes in accordance with my invention. Fig. 4.
is a cross section on the line a. of the tobacco pipe shown at fig. 3.
Fig. 5 shows, in longitudinal section a cigar or cigarette holder as constructed in
accordance with my invention.
Fig. 6 is a detail view.
Referring to fig. 1. of the drawings, the tobacco pipe, as here shown, has its stem
made by preference in two portions, a. and, b. the one part, b. constituting the mouth
piece and being push jointed or screwed into the other, or bowl part, a. As will be
seen the part, a. of the stem, at its end, is hollowed out so as to constitute a
chamber, e. into which I insert a special smoke filtering medium, c. This filtering
medium is what is commercially known as absorbent cotton-wool, which I have found
to be most effectual in eliminating the deleterious and oily ingredients from the
tobacco smoke, and is much better than the materials, such as the ordinary cotton
wool and sponge, which have been heretofore used for this purpose. The part, b. of
the stem, is also hollowed out, and in the hollow a piece, d. of absorbent cotton wool
is inserted. The object of inserting the absorbent in the part, b. is to prevent the
saliva from passing from the mouth of the smoker into the chamber, e. and also to
ensure the thorough elimination of the deleterious and oily ingredients from the
smoke, by causing it to pass through a second filtering medium; before reaching the
mouth of the smoker. A space, as shown, is left between the filtering mediums, c.
and, d, as, should the two pieces of absorbent be allowed to touch each other a
capillary action takes place and the oily ingredients from the tobacco are drawn from
he part, a. of the pipe stem, into the part, b, the efficient action of the pipe being,
consequently, to a great extent, destroyed.
When the pieces of the absorbent have become saturated they can be withdrawn
roun the pipe, by drawing out the part; b, and be replaced by fresh pieces.

page_text: In the tobacco pipe shown at fig. 2. the part, b. has a tubular receptacle for the
pieces of absorbent, fitted to it, the nicotine absorbent being placed at the part, fl of
the receptacle, whilst the saliva absorbent is placed in the part, f2 a space being left
between them, as indicated by the dotted lines. The upper side of the tubular
receptacle is preferably cut away at, f. for the purpose of allowing the pieces of
absorbent, to be easily inserted and removed. Bars may be placed across the tubular
receptacle to keep the pieces of absorbent in place.
In the tobacco pipe shown at fig. 3; the parts, a. and, b. of the stem, are connected
together by a trough, g. of semi-circular cross section (see fig. 4). This trough is or
may be divided into three compartments by bent wires, h. or by bars or their
equivalent, the compartment next the bowl containing the nicotine absorbent, c.
whilst the compartment next the mouth piece contains the saliva absorbent, d. A
ferrule or band, i. capable of being slid backward and forward along the pipe stem,
is provided for covering up the trough, g. On drawing the ferrule or band, i.
backwards, the saturated pieces of absorbent can be easily removed and be replaced
by fresh pieces. A stop, j. is provided to prevent the ferrule or band, i.
coming-off.
In fig. 5. a cigar or cigarette holder is shown, having two pieces of absorbent, c.
and, d inserted in it in the same manner as herein before described with reference
to fig. 1.
.
In fig. 6. a mouthpiece, b. is shown, with a cylindrical shaped absorbent receptacle
so corrugated as to form three compartments, the one, k, being for the nicotine
absorbent, the one, l. for the saliva absorbent, whilst the third one, m. serves to keep
the absorbents separate and at the same time to form a trough for the collection of
any of the deleterious juices from the tobacco. This arrangement of the part, b. of
the stem may, if desired, be used instead of those shown at figs. 2. and, 3.
The various constructions of absorbent receptacle, herein before described as being
used for tobacco pipes, are equally applicable for use with cigar and cigarette
holders.
Although have shown the absorbent as being divided into two parts, it may be
used in one piece, and the absorbent receptacle may be sightly varied from the forms
shown, without departure from my invention.
Cotton wool, sponge, or other, absorbent may, if desired, be used in conjunction with
my improved constructions of absorbent receptacle.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is.
1. In tobacco pipes and cigar and cigarette holders, the application and use of
absorbent cotton-wool for the purposes hereinbefore set forth.
2. In tobacco pipes and cigar and cigarette holders, the making of the stem or
holder in two parts, and the insertion, in each part, of an absorbent, substantially in
the manner herein before described with reference to figs. 1. and, 5. of the drawings
annexed, and for the purposes set forth.
3. In tobacco pipes and cigar and cigarette holders, the special constructions of
absorbent receptacle, substantially as herein before described with reference to figs. 2.
3.4. and, 6. of the drawings annexed:
