An Improved Method of and Means for Removing "Scurf" or
Retort Carbon from Gas Retorts.
I, CHARLES BILLINGTON Junior Albert Terrace Wolstanton, Stoke-on-Trent,
Staffordshire, Brass Founder, do hereby declare the nature of this invention to be
as follows:-
This my invention has reference to an improved method of and means for
removing "retort carbon" or "scurf" from the interior of the cylinders of retorts
used in the manufacture of gas, the object of my invention being to provide an
efficient means for such purpose.
In carrying my said invention into practice I erect or fix a metallic or other
suitable pipe or tube at each side of such retorts near to their front end, on or to
each of such pipes I form or fix any suitable number of screwed projecting
branches for enabling one end of suitable lengths of flexible piping to be attached
thereto, the other end of each length of such flexible piping being suitably con-
nected to one end of a convenient length of removable metallic piping provided
with suitable brackets or bearers placed within each cylinder of such retorts.
will be understood that the pipe at each side of, and near to the front end of such
retorts is connected or joined to one end of a metallic or other suitable tube or
tubes, the other end of such tube or tubes being connected to a suitable blower
or centrifugal fan. When the said retort tubes with their bearers have been
placed within such retort cylinders and connected to the several lengths of flexible
piping, such blower, or the centrifugal fans are set in motion and driven at any
suitable velocity, so that such forced draught is conducted into the interior of each
cylinder of such retorts, the "scurf" or "retort carbon" being blown or removed
through the front or opened end of such retort cylinders by reason of the forced
draught oxidising the "scurf" within such cylinders.

An Improved Method of and Means for Removing "Scurf"
Retort Carbon from Gas Retorts.
I, CHARLES BILLINGTON Junior Albert Terrace Wolstanton Stoke-on-Trent,
Staffordshire Brass Founder, 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 my invention has reference to an improved method of consuming or
loosening or detaching "scurf" or retort carbon from the interior surface of

page_text: gas-retorts, so that such "scurf" or carbon may be readily removed therefrom
without damaging the interior surface of such retorts.
In carrying my said invention into practice I rigidly attach or fix a Roots'
blower, a centrifugal fan or fans or the like appliance to a suitable bed or
foundation in any suitable position, or such blower or like appliance or appliances
inay be rigidly attached or fixed to a suitable platform or carriage mounted upon
wheels so as to enable same to be readily transferred from one place to another
place, or from one retort house to another retort house, an electric motor, a steam
engine, an hydraulic motor or the like may be mounted on, and rigidly attached
or secured to the same platform or carriage as the blower, fan or fans, one end of
a suitable pipe with swivel or socket connections being suitably connected to the
blower or fans used, the other end of such pipe may have a tapering eud, or have
a suitable metallic nozzle attached or connected thereto.
In order that my said invention may be more readily understood and explained
I have hereunto annexed a sheet of drawings upon which letters of reference are
marked on all corresponding parts alike.
DESCRIPTION OF DRAWINGS.
On reference to the drawings hereto annexed, the figure thereon represents a
longitudinal sectional elevation of a gas retort a, to one end of which is attached a
mouth piece b. A portion c of the outer end of a pipe or tube by which forced
draught is conducted or directed against the end or edge of the carbon or
"scurf" d adhering to the interior surface of such retort.
It will be readily understood that when the electric motor, steam engine or other
motor is started or set in motion, a suitable band, rope, chain or the like passing
around a suitable pulley, drum, rigger or wheel fixed on the shaft of the motor and
around a similar drum, pulley, rigger or wheel fixed on or to the shaft of the
blower, fan or like appliance that air will be forced by such blower or the like
through a suitable pipe or pipes, one end of which pipe or pipes are suitably attached
or connected to such blower or fans, the outer portion of such pipe being supported
by any suitable means, or held by a persons hand so that the forced draught
issuing from the outer end, or nozzle of such pipe or pipes may be readily directed
against the lower edge of the "seurf" or carbon adhering to the interior surface of
such retorts, so that such carbon or "scurf" will be consumed, or be rapidly
Such blowers
loosened from their interior surface without damaging such retorts.
or fans may be rotated by suitable toothed wheels gearing or engaging into similar
wheels fixed on or attached to the shaft of the notor employed for driving same,
or such blowers or fans may be rotated by any suitable means to create draught
for loosening or consuming such carbon or "scurf."
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;-
The application of forced draught for cousuming the carbon or "scurf" in, or
detaching or loosening such carbon or "scurf" from the interior surface of gas-
retorts in the mauner bereiu substantially described and set forth.
