IMPROVEMENTS IN TOBACCO PIPES ass
Year: 1884

page_text: I JOHN WRIGHT of Summer Hill Macclesfield in the County of Chester
Gentleman do hereby declare the nature of my Invention for "IMPROVEMENTS IN
TOBACCO PIPES to be as follows:-
"
The object of my invention which is principally applicable to pipes made of
wood is to enable such tobacco pipes to be most effectually cleaned out at any time
in the event of the passage becoming obstructed or to remove the nicotine or other
impurities therefrom.
In the first place I divide the pipe (but not the mouthpiece thereof) in halves
longitudinally by sawing or otherwise, and I connect these halves together at a
convenient point or points, by a hinge, or hinges so that the pipe can be opened
out and closed up again, in a manner somewhat similar to a pipe case.
The end of the stem is made with an external screw and the end of the
mouthpiece is made with a corresponding internal screw so that when the latter
is screwed on it holds the two parts of the stem firmly together.
The upper edge of the bowl is also made with an external screw and an
internally screwed ring is provided to fit thereon so as to hold the bowl together
or unscrewed ferrules or rings may be substituted.
»
The "neb of the pipe
may also be externally screwed and be provided with a screw cap for the same
purpose.
The joint between the two halves of the pipe may be made airtight by a coating
of india rubber or other compressible, but I prefer to make the bowl airtight by
the following means. In one edge I form a groove all round the bowl and I place
a strip of india rubber or other suitable substance in this groove, and on the other
edge I form a corresponding tongue or feather, so that when the two halves are
brought together a perfectly air tight joint is formed, and the india rubber or
other similar substance is not exposed to the fire when smoking.

Gentleman do hereby declare the nature of my invention for "IMPROVEMENTS IN
TOBACCO PIPES" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of my invention which is principally applicable to pipes made of
wood is to enable such tobacco pipes to be most effectually cleaned out at any time
in the event of the passage becoming obstructed or to remove the nicotine or other
impurities therefrom.
My invention is fully illustrated by the annexed drawing which forms part
of this Specification and will be readily understood from the following description
thereof similar letters of reference upon the drawing indicate like parts in all the
figures.
In the first place with reference to Fig. 1. on the drawing I divide the pipe that
is, both the bowl a, a and the stem b, b (but not the mouth piece c, c thereof) in
halves longitudinally by sawing or otherwise and I connect these halves together
at a convenient point or points by a hinge or hinges d, d so that the pipe can be
opened out as shown at Fig. 1 and closed up again as shown at Fig. 2. in a manner
somewhat similar to a pipe case.
The end of the stem is made with an external screw at e, e and the end of the
mouth piece c, c is made with a corresponding internal screw so that when the
latter is screwed on it holds the two parts of the stem firmly together as seen at
Fig. 2.
In Fig. 1. the neb" ff of the pipe is screwed on the outside, and when closed
the bowl of the pipe is held together by screwing a metal cap g, g onto the "neb."
In the modification shown at Fig. 3. the hinge d, d is underneath the bowl and
in this case the upper edge of the bowl a, a is screwed, and the two halves are
held together by means of a screwed ring h, h, The two halves might also be
hinged together as indicated by the dotted lines in Fig. 3.. Unscrewed ferrules or
rings or other similar devices might also be employed for keeping the two halves
of the pipe together when closed.
The joint between the two halves of the stem of the pipe may be made airtight
by a coating of india rubber or other compressible substance but I prefer to make
the bowl air-tight by the following means.
In each edge 1 form a groove all round the bowl and I place a strip of india
rubber or other suitable substance in one of these grooves and in the other I fix
a corresponding tongue or feather i, i so that when the two halves are brought
together a perfectly air tight joint is formed and the india rubber or other similar
substance is not exposed to the fire when smoking.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is
dividing a tobacco pipe longitudinally into halves and connecting the same
together by a hinge or hinges substantially in the manner and for the purpose
hereinbefore set forth and described.
