haldar for making to and to
Year: 1899

page_text: We, STEPHEN WILLINGTON, Gentleman, and ROBERT CHAPMAN FREEMAN,
Technical Instructor, both of 36, Portland Place, Clapham Road, in the County
of London, do hereby declare the nature of this invention to be as follows:-
Our invention relates to pipes for smoking tobacco and to that class of such
pipes wherein the mouth piece is divided longitudinally so as to permit of opening
it out for cleaning purposes.
Pipes of this class as heretofore constructed have usually had the two parts
of the stem pivoted together near the end of the mouthpiece, which construction
necessitates that the jointing surfaces of the two parts should be flat so as to
slide one upon the other, with the result that leakage frequently takes place
and that the parts of the channel adjacent to the pivot are not readily accessible.
According to our invention we obviate these defects by making the two parts
of the stem entirely independent of one another and by providing upon the joint
surfaces ribs and grooves which fit into one another. In order to ensure that the
two parts of the mouth-piece shall be held in close contact we form them
slightly concavo-convex in such a manner that when the two parts are pushed
together into the stem the latter will act as a ring to draw the parts of the mouth-
piece together to form the joint.
In some cases the ribs and grooves may be of dovetailed shape so that the two
parts of the mouth-piece can be connected together prior to applying them to the
stem.
In practice we prefer to provide the portions of the mouth-piece which are
inserted within the stem with a recess or recesses for containing a material
for absorbing the moisture which usually collects in a pipe.

the same is to be performed, to be particularly described and ascertained in and

haldar for making tobacco and to that

page_text: class of such pipes or holders wherein the mouthpiece is divided longitudinally
so as to permit of opening it out for cleaning purposes.
Pipes of this class as heretofore constructed have usually had the two parts
of the stem pivoted together near the end of the mouthpiece, which construction
necessitates that the jointing surfaces of the two parts should be flat so as to
slide one upon the other, with the result that leakage frequently takes place
and that the parts of the channel adjacent to the pivot are not readily accessible.
According to our invention we obviate these defects by making the two parts
of the stem entirely independent of one another and by providing upon the joint
surfaces ribs and grooves which fit into one another.
In some cases the ribs and grooves may be of dovetailed shape so that the two
parts of the mouth-piece can be connected together prior to applying them to the
stem.
In practice we prefer to provide the portions of the mouth-piece which are
inserted within the stem with a recess or recesses for containing a material
for absorbing the moisture which usually collects in a pipe.
In the accompanying drawing:
Figure 1 is a longitudinal section through a pipe made according to the
invention:
Figure 2 is an underside view of the top half of the divided stem; and
Figure 3 is a plan of the lower half of the divided stem:
Figure 4 is a section on the line 4-4 Figure 1:
Figure 5 is a section on the line 5-5 Figure 1: and
Figures 6 to 10 are views similar to Figures 1 to 5 respectively of a pipe
with a slightly modified construction of stem.
a is the bowl of the pipe and a¹ is the portion of the stem formed integral with
the said bowl. b is the upper half of the stem proper and c is the lower part of
the said steni. The upper half b is formed with a central semi-circular channel
or recess d forming a portion of the smoke passage through the stem and also
with lateral grooves c, e running along either side of the semicircular recess d,
the said grooves however, (not extending the whole length of the half stem but
branching off near the mouth-piece at an inclination to the side of the stem as
shewn at f, f and at the inner end branching off to the side of the stem as
shewn at gg. The half stem b beyond the lateral grooves g, g is tapered upwards
as clearly shewn in Figure 1.
The lower half of the stem is formed also with the central semi-circular
recess corresponding with the semicircular recess d so that when the two parts of
the stem are placed together the usual cylindrical smoke passage is provided through-
out the stem. The said half stem is furthermore formed with projections
or ribs, which correspond in position to the grooves e, f, ginto which they fit
when the two parts of the stem are placed together. is a recess formed at the
inner end of the lower half of the stem and adapted to receive material for
absorbing the moisture which usually collects in the pipe.
With this arrangement the two parts of the stem are fitted one upon the
other and passed into the stem portion a¹ of the bowl a, the smoke passage d
coming into alignment with a passage d' formed in the pipe bowl a so that the
smoke and moisture from the pipe pass down through the passage d' into the
recess the smoke then passes down the passage d whilst the moisture is
absorbed by means of the absorbent material contained in the recess j being held
therein by the shoulder j¹ which prevents it passing through the smoke passage d.
To clean the pipe the stem b, c is removed and the parts separated upon which, as
will be perfectly obvious, the whole can be easily cleaned, as each part thereof
is accessible.
In Figures 6 to 10 the stem is shewn as of a slightly modified construction. In
this case in lieu of the auxiliary grooves e, f, g and rihs i, i we employ the smoke
passage d in the upper half b of the stem to receive a central rib k which is of
less depth than the smoke passage d but which fits therein, whilst the stem,

page_text: instead of being divided into two parts along a horizontal plane, is divided along
two approximately radial inclined planes 1, m as clearly shewn in Figures 7 and 8.
It will be obvious that our above described improvements are also applicable
to cigar and cigarette holders.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. In pipes cigar and cigarette holders of the kind wherein the mouth-piece is
divided longitudinally constructing the two halves of the stem independently of
one another and connecting them together by means of ribs and grooves sub-
stantially as, and for the purpose, herein before described.
2. A pipe cigar or cigarette holder of the kind described in Claim 1 wherein
the upper half stem is provided with two grooves and the lower half is formed
with ribs adapted to fit in the grooves and with a recess for receiving absorbent
material, substantially as, and for the purpose, hereinbefore described.
3. In a pipe cigar or cigarette holder of the kind described in Claim 1, the
arrangement wherein the smoke passage is formed in the upper half stem and the
lower half is provided with a rib adapted to partially pass into the said smoke
passage, substantially as herein before described.
4. Pipes manufactured substantially as herein before described and illustrated
respectively in Figures 1 to 5 and 6 to 10 of the accompanying drawing.
