Improvements in Tobacco Pipes.
I, JAMES SAMUEL MERRY of No. 15, Miskin Street, Cardiff, in the County of
Glamorgan, Clerk, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in tobacco pipes and the object of it is to
provide a simple and effective means whereby the nicotine cau be extracted, thereby
preventing by ordinary care being taken, the nicotine from entering the mouth.
In carrying my invention into effect I provide the stem at the bottom of the
bowl with a rabbeted or any other convenient sliding piece-about two inches or
more in length-which is preferably made tapered in the direction of one of its
ends so as to fit perfectly tight when placed in position.
On removing this sliding piece the interior corresponding, to the length of the
slide is exposed, thus allowing the nicotine and other sediments to be removed.
A knob or projection of any suitable shape or form is placed on the sliding piece
preferably under the bowl for removing and replacing it after cleaning.
This sliding piece may be made of the same material as the pipe or any other,
such as vulcanite or silver.
Dated this 5th day of Angust 1893.

COMPLETE SPECIFICATION.
Improvements in Tobacco Pipes.
1, JAMES SAMUEL MERRY of No. 15, Miskin Street, Cardiff, in the County
of Glamorgan, Clerk, 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 :-
My invention relates to improvements in tobacco pipes and the object of it is to
make simple and effectual provision for the easy and practically complete removal
of the nicotine from the stem to the end that its passage into the mouth may be
effectually prevented.
In carrying the invention into effect, I cut away the bottom portion of the stem
so as to expose the bore of it from the point where it turns up into the bowl,
backwards in the direction of the mouth piece for a suitable distance, say for two
or three inches. There is formed a rebate on each side of the bore, the two
rebates converging in the direction of the mouthpiece. In this rebate is fitted a
sliding piece or cover adapted, by fitting the rebate tightly, to close the bowl and
stem for smoking purposes; and, by being made removable, to expose the bore of the
stem and the entrance of it into the bowl.
Provided that the fit and removability of the slide, as the same are specified in
the preceding paragraph, are duly provided for, the details, as well as the material,
thereof may be varied, to any extent.
Suitable provision for moving the slide is made. It may consist of a knob or
notch or the equivalent of either.

page_text: Referring to the accompanying figures :-
Figure 1 is a side elevation of a pipe made according to the present invention.
Figure 2 is an end elevation of the same.
Figure 3 is a side elevation of the improved pipe shewing the sliding piece partly
removed.
Figure 4 is a plan of the sliding piece.
Figure 5 is a side elevation thereof.
Figure 6 is an end elevation.
a is the cavity in the bowl and b is the bore through the stem, both of them as
heretofore.
The stem is cut away on the underneath side of it along the line c from the bowl
backwards nearly as far as the band d, the plane of the cut being below the bore
of the stem. e is a double V groove cut longitudinally in the stem along the
surface exposed by the cut c and deep enough to expose the bore b. f is the sliding
piece. In plan and cross section it fits into the groove e by the tongue f¹ and upon
the surface exposed by the cut c. As the cut c exposes the bore b, part of the
latter is removed. This part is restored to the bore by a supplementary groove
in the slide which makes out the bore when the sliding piece is pushed home, i.e.,
into the position illustrated in Figure 1.
The sliding piece f, the tongue f¹ and the groove e are preferably tapered in plan
so that the slide fits wedgewise in the groove e. The narrow end of the sliding
piece and tongue are bevelled backwards towards the outer surface; the opposite
surface, indicated by the line g, up to which the said end must fit, being undercut
to receive it.
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:-
The hereinbefore described provision for the removal of nicotine from a tobacco
pipe
