Year: 1875

page_text: LETTERS PATENT to Thomas Harman Keble, of Margate, in the
County of Kent, for the Invention of "AN IMPROVED SMOKING
PIPE.'
Sealed the 16th November 1875, and dated the 19th May 1875.
'
PROVISIONAL SPECIFICATION left by the said Thomas Harman Keble.
at the Office of the Commissioners of Patents, with his Petition, on
the 19th May 1875.
I, THOMAS HARMAN KEBLE, of Margate, in the County of Kent, do
5 hereby declare the nature of the said Invention for "AN IMPROVED SMOKING
PIPE," to be as follows :—
I propose to make my improved pipe of any suitable material, but
with a chamber or chambers surrounding the bowl in such a manner
that when the tobacco is lit a current of cool air will be produced, which
> by contact with the outer surface of the bowl will always keep it com-
paratively cool.
I also propose to introduce into the small hole in the bottom of the
bowl a needle, pin. or pricker, preferably knife-edged and of metal

page_text: which pricker will project beyond the said hole, so as to enter the
tobacco when the bowl is charged, and be so arranged that it may be
turned in the bowl, or that the bowl may turn around the pricker.
By turning either the pricker or the bowl, as the case may be, the
tobacco will be lifted and spread if too firmly compressed in the filling
of the bowl, the passage through which the smoke from the tobacco
is drawn to the stem will be scraped clear of any impediment, and
further, the pricker becoming heated while the pipe is being smoked
this heat consumes the poisonous nicotine left in the passage by con-
densation.
:
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Harman Keble in the Great Seal Patent
Office on the 16th November 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
HARMAN KEBLE, of Margate, in the County of Kent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of May, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Thomas Harman Keble, Her special licence
that I, the said Thomas Harman Keble, my executors, administrators,
and assigns, or such others, as I, the said Thomas Harman Keble, 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 Invention for "AN IMPROVED
SMOKING PIPE," upon the condition (amongst others) that I, the said.
Thomas Harman Keble, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Inven-
tion, 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 immediately after the date of the said Letters
Patent

page_text: NOW KNOW YE, that I, the said Thomas Harman Keble, do hereby
declare the nature of my said 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 relates to an improved smoking pipe constructed with a
chamber or chambers surrounding or partially surrounding the bowl,
with the object of keeping it comparatively cool, and with a pin or
pricker, whereby the tobacco within the bowl may be lifted and opened
if too firmly compressed and be kept free from moisture, and by which
the smoke passage is kept clear of every impediment.
°
Similar letters of reference denote similar parts in cach of the Figures
respectively.
A indicates the bowl of the pipe; a, smoke passage; B, outer chamber
with air holes 6; c, plug by which the bowl is socketed in C; C, piece
forming stem, and in which the bowl is socketed; it also carries the pin,
needle, or pricker; d, metal lining of box or socket for plug; d, metal
covering or casing of plug; D, pin, needle, or pricker, shewn detached,
Fig. 3; e, head of pin; f, flattened part of same; 9, point by which
it is plugged in piece O; E, part of C, forming stem; F, mouth-piece;
h, Figure 4 (shown detached, Fig. 5), metal tube lining smoke passage a,
forming also outer covering of plug c, and metal ring' at bottom of
bowl.
It will be seen that the bowl A being simply pushed into the piece C
may be turned within this socket, revolving around the pin or pricker D,
which during this movement will scrape away any matter adhering
to the sides of the smoke passage a, at the same time lifting and
spreading the tobacco within the bowl, and further, this pin D becoming
heated prevents any accumulation of moisture in the tobacco, and will
.

page_text: partially consume the poisonous nicotine left by condensation in the
passage a
I have found by experience that by lining the smoke passage a with
the metal tube h (Figs. 4 and 5) and using the metal lining d I greatly
assist the pin D in drying up moisture and keeping the interior of stem 5
comparatively free from foulness.
The air chamber B, shown on the Drawing as a simple cup, may rise
higher up the bowl, even to its top, forming a single air chamber open
at top and bottom, with any suitable number of perforations above and
below, or forming a series of separate air passages entirely or only 10
partially surrounding the bowl.
The bowl may if desired be screwed into the piece O, so as to turn
round the pin or pricker D by unscrewing. more or less.
Instead of fitting the bowl A. so that it may revolve around the pin
or pricker DI may fix the bowl in the piece C, or make it of one piece 15
therewith, and set the pin D so that it may be turned from below the
bowl or piece C.
The pin, needle, or pricker D' may be made of any suitable metal or
material, and be punched into the piece C, as shewn, or be screwed or
otherwise fitted therein, cither to be turned round the bowl or so that 20
the bowl may revolve round it, and I prefer that it should be flattened
as at f, so as to give free passage to the smoke on both sides, whilst its
knife edges will clear the inner periphery of the smoke passage a, when
bowl or pricker åre turned.
I also prefer giving to this pin D a rounded head, as at e, Fig. 3, as it 25
prevents the small ash of the tobacco falling through the smoke passage a
into the cup below, and I find it lifts and spreads the tobacco in the
bowl and keeps it dry better than any other form of head.
The stem may form part of socketing piece. C, or be screwed therein
or otherwise attached thereto, and both stem E and mouth-piece F may 30
be of any desired shape and material.
The pipe shewn on the accompanying Drawing is merely illustrativo
of my Invention, and I desire it to be understood that I do not limit
myself to any particular shape or configuration of pipe, nor to any
particular material in its manufacture. I would however observe that 35
the design of the pipe shown on the Drawing has been carofully con- . .
