66, Chancery Lane, in the County of Middlesex, Civil Engineer, for an
Invention of "IMPROVEMENTS IN LIQUORING OR CLEANSING SUGAR AND
SIMILAR SUBSTANCES IN CENTRIFUGAL MACHINES." A communication from
abroad by La Compagnie de Fives Lille, of Paris, in the Republic of France.
PROVISIONAL SPECIFICATION left by the said Henry Edward Newton at
the Office of the Commissioners of Patents on the 1st July 1881.
HENRY EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer. "IMPROVEMENTS IN LIQUORING OR
CLEANSING SUGAR AND SIMILAR SUBSTANCES IN CENTRIFUGAL MACHINES."
[A communication from abroad by La Compagnie de Fives Lille, of Paris, in
the Republic of France.]
This Invention relates to an improvement in the liquoring or cleansing of various
substances by steam, either alone or mixed with other gases in a centrifugal machine,
the object being to utilise the centrifugal force for separating from the liquoring
agent the aqueous particles contained therein, such separation taking place before
the entrance of the liquoring agent into the centrifugal machine.
To this end the liquoring agent is projected onto the moving parts of the
centrifugal machine, whence the aqueous particles are thrown off, the liquoring
agent deprived of those particles being allowed to pass into the revolving drum
containing the substance to be treated.
As one mode of carrying out this object, the liquoring agent is introduced to the
centrifugal machine through a circular pipe arranged near the upper edge of
the drum. This pipe is provided at its outer side with openings through which
the liquoring agent passes. The aqueous particles drop onto the edge of the
rotating drum, from which they are thrown by centrifugal force against the walls
of the case, down which they run and are collected at the bottom.

page_text: Or the liquoring agent may be introduced into a cup or basin mounted on the
spindle of the centrifugal machine and turning with it. The centrifugal force
causes the aqueous particles to run up the sides of the cup or basin and throws
them into a circular gutter carried by the cover of the machine. From this gutter
the water is drawn off in any convenient manner, and the dry liquoring agent
escapes into the drum through an annular passage between the edges of the cup
and the gutter.
It will be understood that the liquoring agent may be introduced either above
or below the revolving drum, and that the separation of the aqueous particles
therefrom may be effected by other means than those above described.

the said Henry Edward Newton in the Great Seal Patent Office on the
19th December 1881.
HENRY EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer. "IMPROVEMENTS IN LIQUORING OR
CLEANSING SUGAR AND SIMILAR SUBSTANCES IN CENTRIFUGAL MACHINES."
A communication from abroad by La Compagnie de Fives Lille, of Paris, in
the Republic of France.
This Invention relates to improvements in the liquoring or cleansing of sugar
and other substances capable of being so cleansed by steam, either alone or mixed
with other vapours or gases, in a centrifugal machine, the object of the Invention
being to separate from this liquoring agent the aqueous particles contained therein
by utilizing the centrifugal force for the purpose, the separation being effected
before the entrance of the liquoring agent into the drum of the centrifugal
machine.
To this end the liquoring agent is projected onto the moving parts of the
centrifugal machine, from which the aqueous particles are thrown off by centrifugal
force, and the liquoring agent thus deprived of its moisture passes into the revolving
drum containing the substance to be treated.
In the accompanying Drawing Fig. 1 shews in sectional elevation a centrifugal
machine arranged for effecting the above mentioned object; Fig. 2 is a plan view;
Fig. 3 is an enlarged section of part of the apparatus; and Fig. 4 is a corresponding
plan view.
As will be seen from the Drawing, A. is a pipe which is arranged either in the
form of a ring or of a semicircle over the ledge B of the movable drum of the
centrifugal machine. This pipe, which is connected to the liquoring agent supply
pipe in any convenient manner and receives the liquoring agent, is provided with a
row of holes on its underside through which the liquoring agent passes onto the
ledge B of the drum.
The aqueous particles of the liquoring agent striking on the ledge B during the
rapid rotation of the drum are acted upon by centrifugal action, and are thrown
against the casing G of the centrifugal machine. The aqueous particles run down
to the bottom of the casing, from which they are drawn off by a suitably placed
tap, and the liquoring agent thus deprived of its moisture penetrates into the
drum and acts upon the sugar or other material therein in the well known
manner.
The liquoring agent is introduced into the machine under pressure.
"
It will be understood that the present improvements are equally applicable to
the treatment of boiled masses in centrifugal machines of all systems without
requiring any change in the drums of such machines as to the treatment of raw
sugars with a view to raise the standard and improve the colour.
Having now described the nature of this Invention for Improvements in
Liquoring or Cleansing Sugar and similar Substances in Centrifugal Machines,"
as communicated to me from abroad, and explained the manner of carrying the
same into effect, I wish it to be understood that under the above in part recited
Letters Patent I claim,―
In a centrifugal machine removing from the liquoring agent while in the
machine the aqueous particles contained therein by projecting the liquoring agent

page_text: under pressure from a pipe of small diameter A (arranged in the form of a ring or
of a semicircle above the drum, and perforated with holes or slits on its underside)
onto the ledge B of the drum, as and for the purpose above set forth.
In witness whereof, I, the said Henry Edward Newton, have hereunto set my
hand and seal, the 19th day of December, in the year of our Lord One
thousand eight hundred and eighty one.
H. E. NEWTON. (L.S.)
