PROVISIONAL SPECIFICATION.
Improvement in the Construction of Tobacco Pipes.
We, SAMUEL BOTT and CHARLES TURNER both of 18 New Bartholomew
Street Birmingham Pattern Makers do hereby declare the nature of this invention
to be as follows:-
That there is a saving of 20% of tobacco in smoking and the absorbtion of
nicotine is entirely avoided by the introduction of a trap in the bowl of the pipe
which we propose to make in metal or other suitable material.
The bowl which is in two parts connects itself by an angular grip. The bottom
portion of the bowl has a chamber which is just below a circular perforated plate
and by this means the pipe can be rapidly cleaned.
Dated this Twenty-seventh day of February Eighteen hundred and
ninety-six.
We, SAMUEL BOTT and CHARLES TURNER both of 18 New Bartholomew
Street, Birmingham, Pattern Makers do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
We construct the bowl of a tobacco pipe in two parts; the upper (A) being
detachably connected by screwing or other suitable means to the lower part (B).
This lower part is so turned or otherwise fashioned inside as to form a well (E)
round the part through which the bore from the bowl to the stem (S) passes.
A reference to the drawing, Fig. 1 of which represents the section of a pipe, will
help to explain the construction of a pipe made according to our invention. The
lower part of the bowl is slightly recessed so as to receive the edges of a trap (C)
which we insert between the upper & lower parts of the bowl. This trap, a plan
of which is shown in Fig. 11, may be constructed of metal (in which case we prefer
silver) or bone or other suitable inaterial, and consists of a Hat plate or disc, to the
underside of which a circular collar or ring (D) is attached. This circular collar
or ring is of such depth and is so placed that when the trap is in position between
the upper & lower parts of the bowl the collar or ring shall occupy a position with
reference to the end of the bore opening into the bowl as shown in Fig. 1, leaving
a sufficient area around the opening of the bore to afford a free passage for the
smoke. Holes (about six is a convenient number) to allow of the passage of smuke
are made in the flat plate of the trap between the circular collar and the outer
edge of the plate, as shown in Fig. 11. The upper surface of the flat plate of
our trap forms the bottom of the part of the pipe into which the tobacco is to be
placed.
It is not essential that the bowl should be made in two parts, though this form
seems to us the most advantageous. The bowl may be made in the ordinary way
in one piece, but with a ledge inside it on which our trap plate can rest in a

page_text: position similar to that which it occupies in the form which we have described
.above.
A pipe made according to our invention is readily cleaned, as it can easily be
taken to pieces, & the greater part of the objectionable products of smoking collect
in the well (E) instead of passing into the hore (6), both of which are advantages
arising from our invention. Moreover a eaving of tobacco is effected, since the
whole of that which is put into the pipe can be consumed more thoroughly than in
pipes of ordinary construction.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. The use, as above described, of a trap, constructed substantially as above
described, in a tobacco pipe, the bottom of the bowl of which is hollowed so as to
form a well round the upturned end of the bore leading from the bowl to the stem
substantially as above described.
