IMPROVEMENTS IN PIPES AND TUBES FOR SMOKING
Year: 1879

page_text: LETTERS PATENT to Henry Harbord, of Warwick Lane, in the City of London,
"
Pipe Manufacturer, for the Invention of IMPROVEMENTS IN PIPES AND
TUBES FOR SMOKING."
Sealed the 27th June 1879, and dated the 18th January 1879.
PROVISIONAL SPECIFICATION left by the said Henry Harbord at the
Office of the Commissioners of Patents on the 18th January 1879.
HENRY HARBORD, of Warwick Lane, in the City of London, Pipe Manufacturer.
"IMPROVEMENTS IN PIPES AND TUBES FOR SMOKING."
My Invention has for object to prevent the nicotine and other deleterious
products of the tobacco from passing into the mouth of the smoker, and it is
especially applicable to those pipes having an inclined or partly curved stem, or to
those in which the bowl is situated between the extremities of its stem.
For the purposes of my Invention I fit a hollow cylinder or tube open at both
ends into the stem of the pipe, and I provide such tube with an orifice which lies
exactly under the orifice at the bottom of the bowl. This tube is screw-threaded
at both its extremities, one extremity of which fits into the mouth-piece and the
other into a cup or reservoir destined to receive the nicotine or other deleterious
products.
Wings or guides formed on the tube fit into notches or slots contrived in the
stem, and ensure the orifice in the tube lying directly under that in the bottom of
the bowl; they also prevent the tube from shifting after it has been placed in the
stem.
To clean the pipe the cup or reservoir must be unscrewed, and by blowing
through the mouthpiece the passage of the tube will be readily cleansed, but if
desired a brush or other means may be employed for the purpose; or by unscrewing

page_text: the mouthpiece the tube can be withdrawn from its stem and then cleansed, the
stem of the pipe being always kept dry.
By means of my Invention it will be readily seen that the nicotine is prevented
from being drawn into the mouth of the smoker, for as it enters the hollow
cylinder or tube (within the inclined stem) it runs down into the cup or reservoir,
while the smoke passes up freely in the contrary direction into the mouth of the
smoker without becoming impregnated or saturated with the nicotine by having to
pass over or through it. A "cool smoke" is thus obtained.
My Invention can also be applied to cigar and cigarette tubes or holders.

"IMPROVEMENTS IN PIPES AND TUBES FOR SMOKING."
My Invention relates to improvements in pipes and tubes for smoking, and has
for object to prevent the nicotine and other deleterious products of the tobacco
from passing into the mouth of the smoker; it is especially applicable to those pipes
having an inclined or partly curved stem, or to those in which the bowl is situate
between the extremities of its stem.
My Invention, which will be readily understood on reference to the accompanying
Drawing, is shewn applied to a pipe, in which the bowl is situate between the
extremities of the stem and the mouthpiece curved, it being specially devised for
such pipes.
The Figure in the Drawing represents such a pipe in section, in order that the
interior fitting or arrangement may be fully exposed to view.
For the purposes of my Invention I fit or pass into the stem of the pipe a
detachable hollow cylinder or tube A (shewn partly in section) of ivory, bone,
metal, or other suitable substance, and open at both ends, such cylinder or tube A
being provided with an orifice a, which must lie exactly under the ordinary orifice
or passage at the bottom of the bowl. This cylinder or tube A is screw threaded
at both its extremities, as shewn, one such screw threaded extremity of which fits
into the curved or bent mouthpiece C tapped to receive it, and the other extremity
into a reservoir or cup B, which is destined to receive the nicotine or other
deleterious juices or products of the tobacco.
In order to maintain in place the detachable cylinder or tube A when passed or
fitted into the stem, and to ensure the orifice a in the tube lying directly under
that at the bottom of the bowl and to prevent it from becoming shifted, whereby
its plane portion would close the orifice at the bottom of the bowl and thus prevont
the smoko being drawn into the mouth, I furnish such hollow cylinder or tube
with a wing or guide 6 (or wings or guides), which fits into a notch or excess c
contrived in the oxtremity of the outer and shorter portion of the stem, and thus
the shifting of the cylinder or tube is rendered impossible.
When the cylinder or tube A is in its place the mouthpiece C and cup or
reservoir B are then screwed on and the pipe is ready for use.
In order to clean the pipe, or more correctly the cylinder or tube, the reservoir
or cup B must be unscrewed and the contents can be then emptied or washed out,
then by blowing through the mouthpiece the passage of the cylinder or tube A will
be readily cleansed; but, if preferred, a brush or other suitable appliance may be
used for the purpose.
When however the cup or reservoir is removed the cylinder
or tube will not fall out of the stem but will still be firmly held in place by the
mouthpiece C to which it is screwed, and which is itself prevented from leaving
the tube by reason of the wing or guide 6 retaining it in place. But by unscrewing
both the cup B and the mouthpiece C the hollow cylinder or tube A can be
withdrawn from the stem and then cleansed, the stem is thus always kept clean
and dry.
By means of my Invention it will be readily seen that the nicotine (or other
deleterious products of the tobacco) is prevented from being drawn into the mouth
of the smoker, for as such product (or products) enters the detachable hollow
cylinder or tube A within the stem, it passes or flows down into the reservoir or
cup B, while the smoke, free of impurities, passes in the opposite or contrary
direction into the mouth of the smoker and without becoming impregnated or
saturated with nicotine by having to pass over or through it. A "clean and cool
smoke" is thus obtained.

page_text: Although I have described my Invention as applied to a pipe it can also be
applied in like manner to cigar and cigarette tubes or holders, having a bowl or
other spherical receptacle to receive the cigar or cigarette.
Having now described the nature of my said Invention, and in what manner the
same may be carried into practical effect, I declare that I claim,―
Providing pipes or tubes for smoking with appliances or means whereby the
nicotine or other deleterious juices or products of the tobacco is or are caused to
pass or flow in a direction contrary and opposite to that in which the smoke passes
to the mouth, in the manner herein before described for the purposes set forth, and
substantially as illustrated in the Drawing.
In witness whereof, I, the said Henry Harbord, have hereunto set my hand
and seal, this Fourteenth day of July, in the year of our Lord One thousand
eight hundred and seventy nine.
HENRY HARBORD. (LS.)
