IMPROVEMENTS IN PIPES FOR SMOKING to be as follows:
Year: 1885

page_text: I JOSIAH REDDIE MARTIN MALLETT of 4 City Buildings, Moor Lane in the
City of London, Fine Art Publisher do hereby declare the nature of my inven-
tion for "IMPROVEMENTS IN PIPES FOR SMOKING to be as follows:-
"
The objects of my invention are:-to construct smoking pipes in such manner
that when not in use they can be folded or packed into a small compass and be
therefore more conveniently carried in the pocket; also to prevent them from
imparting a disagreeable odour to the clothing if carried without a case.
.
I make the pipe stem telescopic that is to say, in two or more lengths which
will slide one within another. The portion of the stem which is next to the bowl
may be either permanently fixed thereto in which case the other portions will slide
into it, or it may be removable by unscrewing or otherwise and in this case I may
provide a special aperture or pocket in the side of the bowl to receive the stem
when shut up; when the bowl has a cap or cover this may be made to also form
a lid to the said aperture or pocket: it thus keeps the stem from falling out, and
also prevents the clothing being contaminated with the odour of tobacco, even when
a case is not used. Or the piece of the stem that is next the bowl may be hinged
to it so as, when the stem is shut up, to fold against the side of the bowl; in this
case also the cap or cover of the bowl may be made to cover and hold the end of
the stem.
The points of the telescopic or sliding pieces may be made in any suitable
manner such for example as by a head or flange on the front end of the inner piece
and an inturned flange on the rear end of the outer piece, a washer being interposed
if found necessary.
Or the head of the inner piece may be in the form of a piston
packed with any suitable material.
The stem is preferably made of square or of other than circular form in section
so as to prevent any liability of the bowl turning round when in use..

tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-

I make the pipe stem telescopic, that is to say: in two or more lengths which
will slide one within another. The portion of the stem which is next to the bowl
may be either permanently fixed thereto, in which case, the other portions will
slide into it, or it may be removable by unscrewing or otherwise and in this case
I may provide a special aperture or pocket in the side of the bowl to receive the
stem when shut up; when the bowl has a cap or cover this may be, made to also
form a lid to the said aperture or pocket, it thus keeps the stem from falling out,
and also tends to prevent the clothing being contaminated with the odour of
tobacco, even when a case is not used.
The joints of the telescopic or sliding pieces may be made in any suitable
manner, such, for example, as by a head or flauge on the front end of the inner
piece and an inturned flange on the rear end of the outer piece, a washer being
interposed, if found necessary. Or, the head of the inner piece may be in the
form of a piston ring packed with any suitable material. But in practice I find
it sufficient to make the pieces of plain tubes slightly tapered, the corresponding
tapers when brought together forming a sufficiently tight joint.
i
The stem may be made of square or of other than circular form in section so as
to prevent any liability of the bowl turning round when in use, but I find that if
the pieces be tapered as already mentioned and be well fitted together they are
not liable to turn even when of circular form in section.

The annexed drawings serve to illustrate my invention. Figure 1 represents in
side elevation the several parts of which I make my pipe in the most approved
form. Figure 2 is a side view and Figure 3 a longitudinal section showing these
parts properly fitted together and in position for use and Figure 4 is a side eleva-
tion of the pipe when the several parts of the stem have been slid or telescoped
one within another. The stem is shown as formed of three pieces a, b, c but the
number of pieces may be varied according to the length of stem required. These
pieces are tapered and the piece b is free to be slid into the piece a and the piece c
into the piece b. The piece a is formed at the side with a threaded socket or
projection d to receive the bowl e which, is screwed thereon and the socket.d has
a channel, as shown, to allow the smoke to pass into the stem. The front end of
the piece a of the stem is screw threaded to receive a cap f. When the pipe is
being used for smoking the parts are in the position seen in Figures 2 and 3.
When on the other hand it is desired to pack the pipe into a small compass to
put it into a case or otherwise, the pieces b and c are made to slide into the piece b
and the pipe then appears as seen in Figure 4. In this figure, g represents an

purpose;
this cap
the use of which is optional will prevent the pieces b and c from.
slipping out when a case is not used and will also assist in keeping in the smell.
When it is required to clean the stem the cap fis unscrewed and the pieces b and c
can then be made to drop out of the piece a. I may line the pieces a and b with
flannel or other suitable material that will absorb the nicotine or moisture which
tends to collect in the stem and which when the pieces are slid one within another
would wet the outside of the pieces b and c.
Instead of making the pieces a, b and c plain, as shown, I can make them with
longitudinal or spiral ribs or corrugations, the ribs or corrugations of each piece
corresponding or fitting those in the piece into which it slides or which slides into
it. Or, I can make the piece a with an internal screw thread at its rear end to
receive an external thread at the front end of the piece b and similarly an internal
thread at the rear end of b to receive an external thread at the front end of c, the
pieces when unscrewed sliding or telescoping into each other precisely as in the
arrangement shown in Figures 1 to 4.
Figure 5 is a side elevation and Figure 6 a longitudinal section of a modified
form of my telescopic pipe in which the front piece a of the stem screws into the
side of the bowl e and in which I form a pocket h at the side of the bowl to receive
the stem when shut off; in this case when the pipe is not in use the stem is
unscrewed from the bowl, the parts a, b, c are made to slide one within another
and are then placed in the pocket h. i is a hinged cap or cover which forms a lid
to both the bowl e and the pocket h; it may have a catch to retain it in its closed
position. is a flap hinged to the bowl to close the passage from the bowl when
the stem is unscrewed and thus shut in the smell; this flap should also be fitted
with a catch.
It is evident that my pipe is capable of being modified in various other ways
without departing from the characteristic feature of my invention which is the
making of the stem in two or more pieces or lengths which can slide or telescope
one within another.
It will be seen that my pipe is of simple construction, compact when shut up;
easily taken to pieces, cleaned and again put together; not liable to get out of
order, and that the stem is not liable to clog or get foul.
my
Having now particularly described and ascertained the nature of said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. Constructing pipe stems in two or more pieces which can be slid or telescoped
one within another as and for the purpose set forth.
2. The several arrangements of pipes hereinbefore described.
