Birmingham for an Invention of IMPROVEMENTS IN APPARATUS FOR CLEANING
THE INTERIOR OF TOBACCO PIPES
'PROVISIONAL SPECIFICATION left by the said Sidney Grafton at the
Office of the Commissioners of Patents on the 22nd March 1883:
SIDNEY GRAFTON Engineer of 54 William Edward St Birmingham IMPROVE-
MENTS IN APPARATUS FOR CLEANING THE INTERIOR OF TOBACCO PIPES
My invention relates to an apparatus specially constructed for suspension from
the stem of a tobacco pipe, for the purpose of ejecting the objectionable matter
which accumulates from condensation and is constructed as follows-
A small cylindrical boiler with one end made to screw on, and off, having a hole
through its centre to which is affixed a taper tube bent at right angles for the
purpose of being more easily suspended from the stem of the Tobacco pipe while
the latter is held in a horizontal position
I also provide a second end or cap, but without any hole, so that the small
boiler can be furnished with sufficient spirits which, when required, can be
transferred to a small metal cup which is furnished with a metal gauze
serrated at the edge to induce the expansion of the spirits, thereby giving out
greater heat.
The method of using is as
follows:-
Unscrew the solid end or cap from the boiler, pour the spirit in the cup and
light it, fill the boiler with water, screw on the cap or end having the rectangular
tube, and fix it in the stem of the pipe; hold the boiler in the spirit flame till the
water and steam eject the objectionable matter.
The whole apparatus is enclosed in a box for the waistcoat or other pocket
-

SIDNEY GRAFTON of 54 William Edward Street Birmingham Engineer
IMPROVEMENTS IN APPARATUS
CLEANING THE INTERIOR. OF TOBACCO-
PIPES
FOR
My Invention relates to an apparatus specially constructed to be placed in, or
suspended from, the stem of a Tobacco-pipe
For the purpose of ejecting' the deposit formed by condensation, and is con-
structed as follows
A small cylindrical or spherical boiler having one end to take on, and off, unto
which is attached a graduated tube for the better purpose of fitting into the hole
of the Tobacco-pipe.
The boiler upon being filled with water and heat from a lamp or gas flame being
applied, sufficient pressure is generated to expel the objectionable accumulation
contained in the aforesaid Tobacco-pipe
Or I convert the aforesaid boiler into a generator by dividing it into two
compartments by means of a perforated disc placed midway:
Into one compartment of which I put certain well known chemicals and into
the other compartment I put water or other fluids, and by reversing the position
of the boiler or generator the aforesaid chemicals or fluids come into contact,
when sufficient gaseous pressure is generated to drive the liquids forth to cleanse
the Tobacco-pipe..
Or I use the aforesaid boiler as a condenser having a minute aperture through
the end into which I introduce a rod which by friction or concussion comes into
contact with a pastil or fusee previously placed in the condenser when sufficient
gaseous pressure is developed to force a passage to cleanse the Tobacco-pipe.
Having described the nature of my Invention and the manner of performing the
same I declare that what I claim as the Invention to be protected by the herein-
before in part recited Letters Patent is an apparatus substantially as described
Consisting of a miniature or small boiler, generator, or condenser, to be placed in,
or suspended from, the Tobacco-pipe, having a tube to convey steam, water, or gas,
the whole operating as and for the purpose set forth.
In Witness whereof I the said Sidney Grafton have hereunto set my hand
and seal this twenty second day of September in the year of our Lord 1883.
SIDNEY GRAFTON (L.S.)
