Year: 1874

page_text: LETTERS PATENT to Nicholas Lawrence Tindell, of Crown Buildings,
Queen Victoria Street, in the City of London, Tobacconist, for the
PROVISIONAL SPECIFICATION left by the said Nicholas Lawrence
Tindell at the Office of the Commissioners of Patents, with his
Petition, on the 23rd December 1874.
I, NICHOLAS LAWRENCE TINDELL, of Crown Buildings, Queen
Victoria Street, in the City of London, Tobacconist, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN PIPES AND TUBES
FOR SMOKING," to be as follows:—
The object of my Invention is to prevent nicotine and other deleterious
essential oils or products from passing into the mouth of the smoker, and
to facilitate the cleansing of the pipe. For this purpose I fit a tube or
inner stem into the outer or ordinary stem, which tube or inner stem
is grooved, recessed, hollowed, or trough-shaped; the groove, recess,

page_text: hollow, or trough extending to beneath the bottom orifice of the bowl so
as to receive the nicotine and other prejudicial oils or products from the
kindled tobacco. An orifice is formed at the end near the mouth-picco
and at right angle to its bore in the solid or plane part of the inner
tube or stem to facilitate the smoking of the tobacco without tho
nicotine or other deleterious products passing into the mouth.
Or
the tube or inner stem may be perforated or formed with orifices or
openings to receive such nicotine and deleterious products. Or the
bowl may be connected by a bar, rod, or inside stem with the
mouth-piece. The outer stem may be grooved, hollowed, recessed, or
perforated for the above purpose; or the stem itself may be contrived
with a hollow, grooved, recessed, or perforated portion for the reception
of the nicotine and prejudicial oils or products.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Nicholas Lawrence Tindell in the Great Scal
Patent Office on the 23rd June 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NICHOLAS
LAWRENCE TINDELL, of Crown Buildings, Queen Victoria Street, in the
City of London, Tobacconist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of December, in the
year of our Lord One thousand eight hundred and seventy-four, in tho
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Nicholas Lawrence Tindell, Her
special license that I, the said Nicholas Lawrence Tindell, my exccutors,
administrators, and assigns, or such others as I, the said Nicholas
Lawrence Tindell, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN PIPES AND TUBES FOR SMOKING," upon the
condition (amongst others) that I, the said Nicholas Lawrence Tindell,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and scals, should particularly describe

and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and immo-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Nicholas Lawrence Tindell, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, reference being had to the
accompanying Drawings, and to the letters and figures marked thereon,
that is to say-
The object of my Invention is to construct pipes and tubes for
smoking in such manner as to prevent nicotine and other deleterious
essential oils or products from passing into the mouth of the smoker, and to
facilitate the cleansing of the pipe or tube. For this purpose I fit a tube
or inner stem into the outer or ordinary stem, which tube or inner stem
is grooved, recessed, hollowed, or trough-shaped; the groove, recess,
channel, hollow, or trough extending to beneath the bottom orifice
of the bowl so as to receive the nicotine and other prejudical
oils or products from the kindled tobacco. An orifice is formed at
the end near the mouth-piece in the solid or plane part of the
inner tube or stem, and communicating with the bore so as to facilitato
the smoking of the tobacco without drawing the nicotine or othe
deleterious products into the mouth. Or the tube or inner stem may be
perforated or formed with orifices or openings to receive such nicotine
and deleterious products.

in such stem, and which extends at one end sufficiently far to present
itself under and a little beyond the bottom orifice a of the bowl. bis
the mouth-piece which is connected with the trough or inner grooved or
channelled stem C. Thus the nicotine and other prejudicial oils or
noxious products of the kindled tobacco pass into the trough. At the
opposite end of the trough, channel, or inner stem C, that is to say, tho
end farthest from that which fits into the bowl, is a solid or plane
portion D. In this part is a hole d communicating with the mouth-
piece band with the longitudinal recess or hollow of the trough C. Tho
trough or inner stem C is screw-threaded at the end c nearest the
mouth-piece which is tapped to correspond and receive it. E is a
shoulder on the inner stem or trough C. The arrangement D, d,
facilitates the smoking of the tobacco while preventing solid products or
the prejudicial oils or noxious products of the tobacco from passing into
the smoker's mouth, because the smoke ouly is drawn from the trough
through the orifice d into the smoker's mouth, and the oils and solids are
left in the trough and do not pass into the opening d, as the shoulder E
prevents them from passing into the vent. The troughed or channelled
inner stem can be easily removed, cleansed, and replaced. I is a collar,
ring, or tubular piece of cork interposed between the part D and the
mouth-picce b, and fitted on the hollow screw-threaded end c*, which
forms the connection between the trough and mouth-piece, so that when
the trough C is inserted into the hollow stem B the cork fits tightly
therein and forms an air-tight joint. By these means the pipe is always
kept perfectly clean and a free draught is provided. Morcover, the use
of brushes (which is very objectionable) is dispensed with and what is
known to smokers as a "cool smoke" is obtained.
Figures 6 and 7 are perspective views showing modified constructions
of the trough, channel, or inner grooved stem C. In the arrangement
Figure 6, a hollow cylindrical portion or hood J is formed at the top of
the trough, and is provided with perforations ; on its upper side; this
perforated portion extends for a short part of its length beneath the
bottom orifice of the bowl so as to facilitate the smoking of the kindled
tobacco. In Figure 7 a hollow or semi-cylindrical portion K is formed
on the lower end of the trough and acts as a receiver or cup for the
nicotine or other noxious deposits, and also to prevent such deposits
from soiling the hand of the smoker when the trough is withdrawn from
the bowl and stem for purposes of clcansing.

page_text: In Figure 8, the trough or inner grooved portion B is shown applied
to a bent or curved pipe.
Figure 9 shows, an arrangement in which the outer stem and inner
trough are constructed as described, and made readily detachable and
adaptable to various pipes and pipe bowls.
The troughs or inner grooved stems or channels may be made of bone,
metal, glass, or other suitable material. I also apply the trough or
inner grooved stem to cigar and cigarette tubes in manner similar to
that above described for pipes.
Having now described the nature of the said Invention and in what
manner the same may be performed, I declare that I claim, the con-
struction of pipes and tubes for smoking, in which a grooved, channelled,
or recessed inner stem or a trough-shaped inner stem is employed
communicating and combined with a bowl and a mouth-piece, sub-
stantially in the manner and for the purposes herein-before described.
In witness whereof, I, the said Nicholas Lawrence Tindell, have
hereunto set my hand and seal, this Seventeenth day of Junc,
in the year of our Lord One thousand eight hundred and seventy-
five.
