page_text: I WILLIAM AUGUSTUS FREDERICK BLAKENEY of 14 Fitzwilliam Square in
the City of Dublin late Major 3rd Battalion Highland Light Infantry' do hereby
declare the nature of this invention to be as follows:-
This Invention has for its object the prevention of all access of moisture from
the mouth to the tobacco in the pipe and also the filtration of the smoke during its
passage through the pipe.
According to my invention the bore of the pipe is obstructed about midway by
a short upright tube which I term the overflow tube, passing transversely through
the bore. The upper end of this short tube is covered by a small dome or cap.
screwed or otherwise secured into the stem from the outside. This dome or cap
opens at its lower end into the bore and its upper end projects above the upper
surface of the stem of the pipe. The smoke passes from the bowl through a,
charcoal filter consisting of a small block of charcoal inserted into the stem between
the dome and the bowl and provided with perforations and then passes through a.
hole made laterally in the overflow or upright pipe on the side.next the bowl.from.
which it is drawn through the dome into. the mouth.
All moisture from the mouth will be arrested when it reaches, the obstruction.
caused by the upright tube and cannot reach the tobacco in the bowl unless it rises.
in the cap or dome to the level of the top of the said upright or overflow pipe.
Dated this 10th day of December 1885.

page_text: I, WILLIAM AUGUSTUS FREDERICK BLAKENEY, of 14 Fitzwilliam Square, in
the City of Dublin, late Major 3rd Battalion Highland Light Infantry, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention has for its object to prevent all access of moisture between
the mouth of the smoker and the tobacco in the pipe and also to filter the smoke
during its passage through the pipe.
According to the invention the bore of the pipe instead of being continuous
from the bowl to the end of the mouth piece as usual, is interrupted or obstructed
in its length that is to say, as seen by the accompanying drawings, it is formed in
two parts which have no communication with each other within the stem but are
each brought out to and terminated in openings or holes in the circumference or
outer surface of the stem. The holes are covered or enclosed within a dome or
cap a, screwed or otherwise secured on the stem and under the arrangement shown
in longitudinal vertical section at figure 1, and in plan at figure 2, of the drawings
a short upright tube 6, is screwed or otherwise inserted into the end of that part c
of the bore in direct communication with the bowl d, the effect of which is that
any moisture flowing from the mouth of the smoker through the part g; of the
bore is trapped or arrested within the dome or cap a, and cannot reach the tobacco
in the bowl d, unless it rises in the cap to the level of the top of the said upright
tube b.
By connecting the mouth piece to the stem of the pipe with a " push " joint as
at figure 1, the dome or cap a, may conveniently be turned either upwards or
downwards as desired, when turned downwards as at figure 3, the dome besides
preventing the access of saliva or moisture to the tobacco also acts as a trap for
nicotine and other products of condensation these being deposited in the bottom
of the cap and prevented from running into the mouth of the smoker or as seen
at figure 4, the like objects may be effected by inserting the short vertical tube b
in the part g of the bore and in that case a well or cavity g¹ may be formed under
the tube b to assist in trapping the moisture from the mouth.
Under another arrangement illustrated in longitudinal vertical section at figure 5,
besides the short upright tube b, inserted in the end of the part cof the bore, a like
tube is inserted in the part g communicating between the dome or cap a, and the
mouth, the said tube f, whilst in conjunction with the tube b, serving to prevent
the access of moisture or saliva to the tobacco also, whether the dome a, is carried
above or below the stem, preventing the passage of nicotine to the mouth.
The tubes 6 and f, may have their upper ends bent towards or from each other,
or under the modification illustrated at figure 6, a single bent tube may have its
extremities inserted in the ends of the two parts of the bore an opening / being
made in the crown of the tube through which the saliva or moisture from the
mouth and the nicotine or other products of condensation from the tobacco pass

page_text: into the base of the dome a. To afford additional access to the inner end of the
part g of the bore a removable plug j may be provided in conjunction with any of
the arrangements herein before described, and to filter the smoke a block k, of
charcoal is or may be inserted into the bore at any convenient position between the
dome a, and the bowl, the said block being perforated as indicated at fig. 7.
Figures 4 and 8 illustrate the adaptation of the invention hereinbefore described
to tubes for smoking cigars and cigarettes.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. In a pipe for smoking tobacco an interrupted bore opening at two points to
the circumference or outer part of the stem, a cap covering the said openings and
a straight, bent or other tube or tubes inserted in one or both of said openings to
prevent the passage of moisture through the stem, substantially as described with
reference to the drawings annexed.
2. In a pipe for smoking tobacco the combination of a bore constructed and
furnished as set forth and a filtering block, substantially as described with reference
to the accompanying drawings.
