IMPROVEMENTS IN PIPES FOR SMOKING TOBACCO
Year: 1868

page_text: PROVISIONAL SPECIFICATION left by Jeremiah Lorkin at the Office
of the Commissioners of Patents, with his Petition, on the 20th
October 1868.
I, JEREMIAH LORKIN, of Norwood, in the County of Surrey, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN PIPES
FOR SMOKING TOBACCO," to be as follows:-
This Invention relates to improvements in pipes for smoking tobacco,
and consists,-
Firstly. In applying the light to the tobacco in the pipe at the
bottom end thereof instead of at the top as usual; the said pipe hanging
down from the mouth vertically instead of projecting horizontally or
nearly so as at present.
Secondly. In purifying the smoke emanating from the tobacco
by causing the essential oils therefrom to be deposited on layers of
material placed in a receptacle through which the smoke passes.
And, thirdly. In purifying the smoke emanating from the tobacco
by causing the essential oils to be extracted therefrom by chemical
means.
My improved pipe may be of any suitable form or shape, and
constructed of any suitable material, but I prefer that the base thereof

page_text: should be smaller than the upper extremity, so that the unconsumed
tobacco in the upper part of the bowl may be prevented from falling
on the lighted tobacco in the lower part thereof, and thereby
extinguishing the same. The pipe is provided with a cap or cover at
its upper extremity which may be either screwed, tightly fitted, hinged,
or otherwise fastened to the bowl, and when it is required to load the
said pipe this cap or cover is unscrewed or otherwise removed, the
tobacco put in the bowl from the top, and a light applied at a hole
provided at or near the base thereof, there being a receptacle screwed
or otherwise fastened to the said bowl below the hole, into which the
ash falls and which serves as a stand for resting or placing the pipe
on a table or otherwise when required, the said receptacle being enlarged
at the base for that purpose. In the said cap or cover or in a
receptacle provided for the purpose are one, two, or more scives or
strainers on which are deposited layers of granulated coke or other
suitable material; the smoke passing through the said seives and layers
will deposit thereon the moisture or essential oils contained therein,
thus preventing their entrance into the mouth, a source of so much
inconvenience and unpleasantness in the present form of pipes. Or,
sponge, wool, or other fibrous material soaked in alcohol or other
purifying agent may be placed in the said receptacle, by which means
the moisture or essential oils will be extracted from the smoke on
its passage to the mouth. A coil or coils of gutta percha, caoutchouc,
or other flexible tubing, a part of such tubing forming the mouthpiece,
may be attached to the receptacle above mentioned, the length of the
coils serving to cool the smoke as it passes through them, and the gutta
percha or other flexible mouthpiece saving the teeth from the wear
occasioned by constantly gripping hard substances, such as amber,
bone, &c. as at present.
It will be observed that my improved pipe may always be carried
or placed in a vertical position, by which means the leverage caused
by the weight of the bowl of the pipe projecting horizontally or nearly
so from the mouth is considerably diminished or wholly prevented,
and the draught on the lungs greatly reduced; I also place on the
cap or cover when required a vessel of any suitable size, shape, and
material for containing water, alcohol, or other purifying agent supplied
thereto through a pipe extending down into the said liquid, so that no
smoke may escape therefrom, and having the tube from the bowl of the
pipe projecting into the said vessel; over the orifice of, and at a suitable

page_text: distance from the said tube I place a shield projecting downwards,
and terminating in a diaphragm covering nearly the whole of the
bottom of the vessel and placed at a little distance therefrom, so that
the smoke on passing between the diaphragm and the bottom of the
vessel is, as it were, broken up or separated into minute particles
and passes in that form through the water, alcohol, or other purifying
agent; or, if preferred, charcoal or other purifying material may be
placed between seives or strainers in a similar receptacle to that above
mentioned, the smoke passing through the said scives and purifying
material before it reaches the mouth, by which means the strongest
tobacco may be rendered comparitively mild, and much injury to the
smoker avoided by the exclusion from the lungs of the nicotine and
other poisonous exhalations.
