Improvements in or relating to Smoking Pipes.
I, JAMES PILKINGTON, of 6, Chiswell Street, Kensington, Liverpool, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object a pipe or its appurtenances whereby the bore
will be always free or can be kept free of nicotine deposit, and the cleaning device
will be always in place.
As the
It consists essentially of a flat spring steel or other like suitable material very
thin and in width about the diameter of the hole of the pipe, and of the same
length as the bore of the pipe. To the end of this plate is soldered a little silver
or other disc. Excentrically and in the centre of this disc is a hole opening close
to the plate. This little device is run into the pipe and kept there permanently.
When the pipe becomes foul the disc is simply turned round the plate withdrawn
and the nicotine deposit scraped or wiped off it and the plate returned.
hole in the disc corresponds practically with the hole in the mouthpiece the disc
which is of slightly less diameter than the mouthpiece forms no impediment in
smoking and remains permanently in the pipe and therefore cannot be lost while
the plate being bent rather more than the pipe by its resiliency has sufficient
resistance to prevent it falling out and getting lost. It is obvious however that
any other device such as a screw tube at the end whereby the scraper can be
kept secured in the pipe will answer the same purpose of holding it safely.

improvements in or relating to Smoking Pipes.
I, JAMES PILKINGTON, of 6, Chiswell Street, Kensington, Liverpool, in the
County of Lancaster, Engineer, 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:-
This invention has for its object a pipe or its appurtenances whereby the bore
can be always freed or can be kept free of nicotine deposit, and the cleaning
device will be always in its place.
The invention will be understood from the following description, reference
being had to the accompanying drawings, in which.

page_text: Figure 1 is a general view of the cleaner separated from the pipe;
Figure 2 an elevation of a straight stem pipe with the cleaner in place;
Figure 3 an end view of the pipe mouthpiece;
Figure 4 the application of the invention to a bent pipe.
The invention consists essentially of a flat blade of steel A, or other like suitable
material, very thin and in width about the bore B of the pipe or something less.
As depicted in Figures 1 and 2, it is of the same length as the bore. To the end
of this blade is soldered or rivetted a little silver or other disc or tip C eccentric-
ally; and in the centre of this disc is a hole c (or it may be slit) opening close to
the blade A. This little device is run into the pipe and kept there permanently.
When the pipe becomes choked the disc is simply turned round and the blade
withdrawn, the nicotine deposit wiped off and the blade or cleaner returned.
As the small hole in the disc corresponds practically with the hole B in the
mouthpiece, the disc C which is of slightly less diameter than the mouthpiece,
forms no impediment in smoking and is a vast improvement, as from experience
it not only makes the smoking dry and cool but prevents either nicotine or small
bits of tobacco from entering the mouth. In order to prevent the cleaning device
being lost or dropping out of the pipe, the blade has a slight bend in it, which
acts as a spring and further serves another purpose of giving a better scraping
action assisted by the eccentric action of the disc.
It is obvious that I do not confine myself to making the blade the full length
of the bore, as in some cases, more particularly in the case of curved pipes, it may
be convenient to make it of short length as indicated in Figure 4. In this case
after the mouth piece has been cleaned, the stem of the pipe can be cleaned by
unscrewing the mouthpiece, removing the cleaner therefrom, and applying it
to the bore in the stem.
The invention is not of course confined to a flat blade, as a round, square or
other shape wire or blade may be used instead, also it is obvious that instead of a
disc at the end, the extreme end of the wire may be bent at right angles to form
a stop which however forms no impediment in smoking.
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:
-
1. As an improved article of manufacture, a cleaner for tobacco pipes, consisting
of a thin wire or blade of steel or other springy material of any desired section
and in width something less than the bore, having a bend in it about the middle
of its length which acts as a spring and further serves the purpose of giving a
better scraping action in the bore, and a little disc or tip secured to the wire or
blade at one end eccentrically, with a hole in the centre or a slit opening close
to the wire or blade, substantially as described.
2. A cleaner for tobacco pipes formed of a slender wire or blade of springy
material having a bend in the middle, and its extreme end bent at right angles to
form a stop substantially as described.
