AN IMPROVED SMOKING PIPE
Year: 1883

page_text: LETTERS PATENT to Robert Calder Christian of 70 Euston Terrace, Ranelagh
Road Dublin in the county of Dublin, Ireland, for an Invention of "AN
IMPROVED SMOKING PIPE "
PROVISIONAL SPECIFICATION left by the said Robert Calder Christian at
the Office of the Commissioners of Patents on the 25th January 1883.
ROBERT CALDER CHRISTIAN, of 70 Euston Terrace, Ranelagh Road, Dublin, in
the County of Dublin, Ireland. "AN IMPROVED SMOKING PIPE."
G
The object of my Invention is to produce a pipe for smoking purposes of simple
construction and with a view to cutting off all connexion between the stem of the
pipe and a reservoir provided for the reception of oily or other deleterious matter
contained in tobacco.
For this purpose I construct the bowl of the pipe of an outer and inner chamber,
the inner chamber being provided with a thread round a portion of its outer
surface to facilitate its being screwed into position within the outer chamber;
and in the bottom of this inner chamber a conical shaped passage or aperture is
formed which fits into the mouth of a vessel or reservoir'attached to the lower
part of the outer chamber so that any oily matter contained in the tobacco passes
through this conical shaped passage or aperture into the said vessel or reservoir
whence it can be removed at pleasure.
In the sides of the inner chamber are pierced three or more holes or passages in
a diagonal manner commencing at the lower part of the interior of the said inner
chamber and having their exits at the upper part of the outside of same. Through
these holes or passages the smoke can be drawn from the bottom of the inner
chamber thence through the annular space between the two chambers to the
mouth of the smoker free from and unimpregnated with any oily matter, which
latter escapes as above stated through the conical passage or aperture at the
bottom of the inner chamber to the reservoir provided on the outer chamber.

by the said Robert Calder Christian in the Great Seal Patent Office on

ROBERT CALDER CHRISTIAN, of 70, Euston Terrace, Ranelagh Road, Dublin, in
the county of Dublin, Ireland, "AN IMPROVED SMOKING PIPE."
The object of my Invention is to produce a pipe for smoking purposes of simple
construction and with a view to cutting-off all connexion between the stem of the
pipe and a reservoir provided for the reception of oily or other deleterious matter
contained in tobacco.
For this purpose I construct the bowl of the pipe of an outer and inner
chamber, the inner chamber being provided with a thread round a portion of its
outer surface to facilitate its being screwed into position within the outer
chamber. In the bottom of the inner chamber a passage or aperture is formed
which fits into the mouth of a vessel or reservoir attached to the lower part of
the outer chamber so that any oily matter contained in the tobacco passes through
this passage or aperture into the said vessel or reservoir whence it can be removed
at pleasure.
In the sides of the inner chamber are pierced three or more holes or passages in
a diagonal manner commencing at the lower part of the interior of the said Inner
chamber and having their exits at the upper part of the outside of same. Through
these holes or passages the smoke can be drawn from the bottom of the inner
chamber thence through the annular space between the two chambers to the mouth
of the smoker free and unimpregnated with any oily matter which latter escapes
as above stated to the reservoir provided on the outer chamber.
The accompanying drawings will enable the nature of my said Invention to be
more clearly understood.-Fig. 1. is an elevation and fig. 2 a vertical section of
the improved pipe. a, a, represents the inner chamber or bowl which drops into
the outer chamber b. b. and is secured by the threaded screw c, c.
The bottom
being elongated passes through an aperture in the bottom of the outer vessel as
shown, where the reservoir or vessel d is attached by means of a threaded screw so
that it can be removed at pleasure. e, e, show the diagonal holes pierced in the
sides of the inner chamber through which the smoke is drawn from the interior of
the bowl as already described
→
Having thus described the nature of my said Invention and the manner of
applying same in practice, I would have it understood that what I consider new
and useful and therefore claim as the Invention to be secured to me by the
herein before in part recited Letters Patent is:-
1st. The use and construction of pipes for smoking tobacco whereby a complete
separation of smoke from oily matter contained in the tobacco is effected
substantially in the manner herein specified and set forth.
2nd. The elongation of the bottom of the inner chamber or bowl so as to
penetrate an aperture formed in the bottom of the outer chamber or bowl,
substantially in the manner and for the purpose herein specified.
3rd. The diagonal holes or passages pierced in the sides of the inner chamber or
bowl substantially in the manner and for the purpose herein set forth.
In Witness whereof, I, the said Robert Calder Christian, have hereunto set
my hand and seal this Twenty-first day of July, in the year of our Lord,
One thousand, eight hundred and eighty-three.
