Improvements in Devices for Cleaning Tobacco Pipes.
I, EDWARD WILLIAM EVANS, of 214, Chester Street, Birkenhead, in the
County of Chester, Tinsmith, 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 device for cleaning tobacco pipes from
accumulations of nicotine, saliva and the like.
It will be understood from the following description, reference being had to the
accompanying drawing, which shows a front elevation, partly in section, of my
invention in use with a tobacco pipe applied thereto.
In this drawing A is a metal vessel or boiler adapted to contain water, B its
handle, C a stem or mouthpiece screwed to the vessel A and adapted to be
unscrewed therefrom when required. D a cork or other suitable nozzle and E the
tobacco pipe. In use the stem C is unscrewed from the vessel A and the latter
filled with water. The vessel is then placed over a gas jet, fire or other source of
heat, and the tobacco pipe which requires cleaning, has its bowl inserted on the
nozzle D. As soon as the water boils, steam and boiling water will be ejected
through the stem C, into the pipe bowl, and from thence through the stem, the
nicotine and other impurities being thus ejected by the boiling water and steam
through the mouth piece of the pipe.
I have described the above way of carrying my invention into effect, but it must
be understood that I do not confine myself to the exact arrangement shown, as
certain alterations may be made without departing from the invention. Thus,
instead of the handle B, a handle may be employed for suspending the device over
a flame, and instead of making a straight stem, the stem may be bent so as to
bring it out of the direct line of the heat and products of combustion. The
vessel A may be formed, as shown in the drawing, with a flat bottom and sloping
sides against which the heat impinges so as to get the greatest amount of heating
effect therefrom. It must be understood however that I do not confine myself to
any particular shape of vessel; and furthermore instead of the stem C unscrewing,
it may be fixed to the vessel 'and a separate screw plug provided for filling the
vessel with water.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. An improved device for cleaning tobacco pipes, consisting of a stem or
nozzle, the end of which is adapted to be received by the bowl of the tobacco
pipe, in combination with a vessel or boiler containing water and adapted to be
heated by holding the same over a gas jet, fire or other source of heat, whereby a
continuous jet of steam or boiling water is injected through the pipe so long as
the water in the vessel boils, substantially as described.
2. In a device for cleaning tobacco pipes by boiling water and steam, forming
the vessel or boiler in which the steam is generated with sloping sides against
which the heat impinges, substantially as set forth.

page_text: 3. The improved device taken as a whole for cleaning tobacco pipes from
accumulations of nicotine, saliva and other impurities substantially as described.
