COMPLETE SPECIFICATION.
Improvements in connection with Pipes for the use of Smokers.
I, JOHN FISHER FLEWKER, care of The Credit Lyonnais Bank, 40, Lombard
Street, E.C., London, and of Bombay, East India, Accountant, 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 connection with pipes for the use of
smokers, and the objects are to provide a pipe having variable draught passages,.
and means for reducing the risk of nicotine passing into the smokers mouth. In
order to more clearly describe my invention, I make reference to the accompanying
sheet of drawings in which Fig. 1, is a vertical section, Fig. 2, a horizontal section,
Fig. 3, a view of one end of the mouth-piece. Fig. 4, a cross section through Z Z
of Fig. 2. Figs. 5 and 6 are vertical sections of two modifications of my pipe.
Figs. 1 to 4, refer to a pipe the air passages or draughts" of which are variable
in three ways. Fig. 5, refers to a pipe with air passages variable in two ways..
Fig. 6, refers to a modification of the pipe Figs. to 4. Similar letters denote
similar parts wherever occurring. The bowl a is provided with an inner cup b
having the perforated bottom 6. Below 6' is the grating c and at the bottom of
the bowl a is the nicotine chamber d screwing thereon, to which chamber may
also be attached a (preferably glass) supplementary nicotine chamber e. Opening
into a below c are the two bores f and g. The bowl a screws on to the stem
which is provided with a socket i to slip over the neck k at the end of the mouth-
piece 1. The mouth-piece has the projecting tongue m and a bore n extending
from the end of m to the end of 1. In the end of the neck k are screwed three
comparatively short plugs o, p, q. The plug o enters the end of the bore run-
ning through the stem, the end of being coincident with the bore g in the bowl a.
penters the bore f', the end of which is coincident with bore f in a.
plug 7 simply enters the blind hole s at the end of stem h. The centre of h is
bored out at t to a diameter greater than that of m, so as to leave an annular space
round it, and of such length that m does not reach to the end of t.
The space
between the end of m and the end of t is filled with any suitable absorbent, but
not air tight material u. Passing from side to side of the stem part of a is the
hole through which is passed the tube w having a head at one end and a screw
nut y at the other. The tube w is perforated at 2 and A.
The hole at z goes
The other
right through, and is in communication with the bores f and f¹. The hole at A
is in communication with bore B extending from near the bowl end of h to the
mouthpiece end thereof. In k is a cavity C starting at the periphery of k_and
passing down and forwards and dying out on the surface of the tongue m.
In a
pipe thus made the "draught" is variable in three ways: -
1. Assuming everything in the position shown in Figs. 1 to 4, the draught will
pass from along w, along B through C, through t and thence to the bore n of the
mouthpiece 7.
2. Remove the mouthpiece and place it with cavity C over p. Passages r and B
will then be plugged at the ends and the second "draught" is from f along fl
through C through f and thence to the horn » of the mouth.

3. Remove the mouthpiece and place it with cavity C over r, the passages p
and B will then be plugged at the ends, and the third "draught" will be from g
along through C through t, and thence to the bore of the mouthpiece. It must
always be borne in mind that the plugs o, p, q, are fixtures at the end of the neck k,
and come away with the mouthpiece for the necessary action in plugging the
bores in succession as already described.
In the modification shown by Fig. 5, the course of the draught can be changed
in two ways. 1st. Assuming everything to be as in the drawing, the first draught
will be from f along f¹ through C into t, thence through u to the bore n of the
mouthpiece 1. 2nd. Remove the mouthpiece and put plug p in end of fl, then
the second draught will be from 9 along ŕ through C into t through u, and thence
to bore n of the mouthpiece 7.
g
In the modification shown by Fig. 6, the course of the draught can be changed
in three ways. I provide a tube D screwing on at E so as to communicate with
passage v. The other end of D pushes tightly into i. The tube D can be screwed
off from the position shown in Fig. 6, and screwed on at E' shown in dotted lines.
The opening at E is then closed by a suitable screw plug or stopper. The opening
at E' can be closed by the same stopper, when the tube D is as shown in Fig. 6.
The three draughts are as follows:-1st. Assuming everything to be as in the
drawing, the first draught will be from g along v, f¹ to C, thence along through u
to bore n of mouthpiece l.
2nd. Remove the mouthpiece l, and place o in the end of f¹, the second draught
will then be from g along r, through C thence along through u to bore n of the
mouthpiece 7.
3rd. By removing the tube D and screwing it on at E¹, stoppering the opening
at E and placing o in f, communicating with E, the draught will be in the posi-
tion shown in Fig. 6, the only difference in the arrangement being that the pipe D
is at the side instead of at the top as shown in the fig.
Any of the longitudinal air passages may slope or incline from one end to the
opposite end instead of being parallel as shown in the drawings, and may also
vary in diameter from end to end.
I do not confine myself to the precise shapes shown in the drawings, nor to the
relative proportions or disposition of parts, as they are capable of some variation
without departure from the essential features of the invention.
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:
