page_text: COMPLETE SPECIFICATION.
I SAMUEL SEALY ALLIN of Woodstock Road Bedford Park in the County of
Middlesex Gentleman do hereby declare the nature of my Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF PIPES, AND CIGAR AND CIGARETTE
HOLDERS, AND IN THE MEANS OF CLEANING THE SAME" 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 this Invention is to improve the construction of pipes, and Cigar
and Cigarette holders, to prevent the moisture of the Tobacco, which is charged
with essential oil and nicotine from accompanying the smoke into the mouth of
the Smoker, to prevent its return into the bowl, to cool the smoke, and to facilitate
the cleaning of such pipes and Cigar holders.
And the improvements consist
In forming the pipe in three sections, the bowl, the stem, and the mouth piece,
each constructed with a view to a special result.
In the employment of a filter, which both filters and cools the smoke and being,
when required, pushed as a piston through the stem cleans it out.
In the employment of screws of quick pitch with two or more threads, instead
of one, to connect the parts, which while giving a very firm hold, permit the
joints to be opened with a half turn or less. In the employment of right and
left handed screws to attach the bowl and mouth piece to the stem.
In order that the Invention may be well understood and explained in detail
I have hereunto annexed a Sheet of Drawings made about full size, upon which
letters of reference are marked on all the Figs alike.

In these Figs a is the bowl b the stem and c the mouth piece, The passages
from the bowl a and mouth picce c are not bored concentric with the stem, (see
Fig 3) and this is especially necessary with that from the bowl a, at which end
most of the liquid lies, but are so arranged that when the parts are put together to
form the pipe, (see Fig: 1.) their apertures open into the cavity of the stem b,
(which is of considerably larger bore), close to its upper surface, These apertures
terminate in nozzles a¹ and c¹ which project into the cavity of the stem b leaving
beneath them spaces in which liquid can lie without risk of entering the apertures,
while the pipe is in use. The bowl a and mouthpiece o fit into the stem b. nt
either end with plugs, screws, or any other suitable joints In the drawing screws
are shewn, one being a right handed and the other a left handed screw thread of
the ordinary type also in Fig 10 is shewn a screw with three threads.-The wear
of one compensates for the wear of the other, and so prevents the inconvenience at
present found of the bowl getting out of line with the mouth piece, in consequence
of the wearing of the screw thread, which always occurs when only one screw is
used, or two screws having the same direction.
The Stem is bored of a diameter so large as to admit of the space beneath the
nozzles a¹ and c¹ above described and such bore is of uniform diameter throughout
its length, or very slightly tapered so that the piston filter d when being pushed
through to clean it, may press firmly all round, or with a very shallow shoulder to
regulate the position of the filter, which should stand clear of both nozzles. It
is essential that the filter shall be non-absorbent; incorrossible, and a good
conductor of heat. I therefore make it of metal, and what I find best adapted to
the purpose, is a disc of fine wire gauze, preferably of silver, as it neither corrodos,
nor does it become foul by absorbing the moisture and essential oil, nor does it
hold a film of dirty fluid across the path of the smoke, as do all porous filters, and
those possessing any appreciable power of capillary absorbtion. The character
and shape of the metallic filter being such, that it divides the smoke passing to the
mouth of the smoker into numerous minute streams. In consequence of this
sub-division, and because the material of the filter is a good conductor of heat,
the moisture and nicotine of each stream are extracted from the smoke and
deposited on the metallic surface of the filter, from which the liquid drains into
the chamber of the stem b, leaving the oily matter on the filter. The stem b
containing the condensed moisture with its impurities, when removed from the
bowl a is easily cleaned by simply throwing out the liquid, and the metal gauze
filter is cleared by removing the mouth piece and by blowing strongly from that
end through the stem, which removes all the matter deposited on the wires, and
leaves then bright. Nothing more is required if the pipe is in regular use, but if
it has been lying by, the deposit on the inside of the stem will have become
sticky, and in such case, the filter should be pushed through as a piston to scrapo
it all out a purpose to which its shape and material adapt it, and a fresh filter put
in, or the old one cleaned and replaced.
The construction of my improved Cigar holder is scon at Fig 9 in which a is
the holder, b the mouth piece & the filter. In a holder of this description, it is not
necessary to make the tapered portion of the holder which receives the cigar and
which corresponds to the bowl of a pipe a separate section, as it is small and in
line with the stem, and easily cleaned without removal, but those Cigar holders
which have a pipe shape I construct in manner similar to the pipe above
described.
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:-
First The forming the bowl and stem with apertures bored out of contre with
the stem and with nozzles so bored projecting into it noar its upper side, either or
both of them, substantially as described.
Second The employment of a Silver wire gauze filter, substantially as described.

page_text: Third The employment of a metallic filter with power of rapid conduction of
heat for the purpose of cooling the smoke, and precipitating moisture and oil,
substantially as described.
Fourth The employment of a filter, incorrossible non-absorbent, and with little
or no power of capillary attraction, substantially as described.
Fifth The employment at opposite ends of tho stem of right and left handed
screws, and
Sixth The employment of screws with two or more threads, instead of one, to
obtain a combination of quick opening and closing the joints, with a very firm
hold and good wearing power.
