invention to be as follows:-
The object of my invention is to remedy certain defects in tobacco pipes as:
heretofore constructed and also to combine therewith certain useful articles, such as
a stopper or plug, pricker, and other similar smoker's requisites.
In carrying out my invention, I fit, an annular chamber at the end and preferably.
outside of the stem of the pipe in such a manner that the nicotine and other
deposits may readily enter such chamber. The mouthpiece is fitted at the other-
end of this chamber, the mouthpiece being formed with a projecting tube to prevent
the nicotine entering the mouth of the smoker when reclining.
In or at any suitable part of the pipe I insert or attach one, two or more useful
articles known as smoker's requisites in such a manner that their addition does not
detract from the appearance of the pipe, nor render the pipe cumbersome.
It will be readily understood that my improved pipe may be placed in any
position with perfect immunity as my before mentioned improvements prevent any.

Improvements in Tobacco Pipes.
1, JAMES GEORGE STIDDER, of Erseldoune, Wadden Old Road, Croydon, in-
the County of Surrey, Sanitary Engineer, do hereby declare the nature of my
said invention 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 is to manufacture improved tobacco pipes, the
construction being so arranged as to prevent poisonous nicotine passing into the
mouth also to improve the combustion of the tobacco in the bowl, so as to ensure
its burning bright and evenly to the last particle.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which.
similar letters of reference indicate corresponding parts.
Fig. 1 shows one form of my improved pipe.
Fig. 2 is a longitudinal section of the same.
Fig. 3 is a section on the line 1-2 of Fig. 1.
Fig. 4 illustrates another form of my invention, partly in section.
The pipe consists of two principal parts: the stem a, formed in one with the
bowl b; and the mouth piece c. At the junction of the stem and mouth piece, I fit
a nicotine trap d; consisting of an annular chamber, having tubular ends dd, into
which the stem and mouth piece are screwed, and whereby they are held together. e is
a trumpet shaped tube, one end of which enters the bowl, the other end extending
about half way into the chamber d. Rings of rubber or other suitable material
surround the tube e, at fg, to form air-tight joints. An annular space h is thus
formed round the tube e, into which three air holes open, one at k, near the bowl,
and one ou each side at m, near the rubber ring g, for the circulation of air and

cooling of the tube e and stema. The air holes may be omitted in some cases.
A ring may be fitted to cover the hole k, if required, the ring having a corre-
sponding hole to uncover the air-hole k, by rotation, or it may be made to cover
and uncover by sliding upon the stem. A passage o opening into the bowl at one
end, and the air hole k at the other, is sometimes added, to assist the combustion by
the admission of air, more especially when the tobacco is pressed down too hard.
is a pricker, retained in a perforation under the bowl, ready for use. The mouth-
piece is fitted with a tube to prevent the passage of nicotine from the chamber d
to the mouth-piece passage ».
P
In the modification shown in Fig. 4, the trumpet shaped passage e¹ is formed in
the stem itself, and the head of the pricker p¹ is moulded to fit the bowl and for
use as a stopper, a small break being provided for the reception of the finger
nail, in drawing it out. The annular chamber h and air passages km and o are also
omitted.
The mouth piece (separated from the stem) may be fitted with a cigar holder,
and thus used for smoking cigars.
The pipe may be placed in the pocket or elsewhere in any position, without the
nicotine in the chamber finding its way into the bowl or the passages of the
mouth piece.
The nicotine which collects in the chamber d, may be removed by simply
unscrewing the mouth piece, and emptying it out of the chamber d.
In some cases I form transverse grooves or indentations on the mouthpiece or
stem to afford better grip for the fingers when holding the pipe.
My improved pipes are manufactured from any ordinary materials, and suitably
mounted with silver or otherwise.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. An improved tobacco pipe, having an annular chamber d interposed between
the stem and the mouth-piece, the stem having a central trumpet-shaped tube e, an
annular air chamber h, with or without air passages k, m, and o, a ring n and
pricker p; and the mouth piece c having a tuber fitted thereto, substantially as
and for the purposes herein before described, and illustrated by Figs. 1, 2 and 3 of
the drawings.
2. An improved tobacco pipe, having an annular chamber d interposed between
the stem and the mouth piece, the stem having a central trumpet shaped passage
el
formed therein, and a pricker p; and the mouth piece chaving a tube fitted
thereto, substantially as and for the purposes herein before described, and
illustrated by Fig. 4 of the drawings.
3. The improvements in tobacco pipes, substantially as herein before described.
