45, Bedford Row, London, W.C., for the Invention of "IMPROVEMENTS IN
MACHINERY FOR COOLING AND CLEANING Coffee, Tea, CoCOA, AND CHICORY."
Sealed the 30th March 1880, and dated the 8th October 1879.
PROVISIONAL SPECIFICATION left by the said Francis George Fleury and
Edward Dunning Barker at the Office of the Commissioners of Patents on the
8th October 1879.
FRANCIS GEORGE FLEURY and EDWARD DUNNING BARKER, of 45, Bedford Row,
London, W.C. "IMPROVEMENTS IN MACHINERY FOR COOLING AND CLEANING
Coffee, Tea, COCOA, AND CHICORY."
This Invention has for its object improvements in machinery or apparatus for
cooling and cleaning coffee, and relates to that class of machinery or apparatus for
the purpose named in which a revolving perforated table is used working on a
vertical shaft or spindle. According to our Invention. This revolving table having
its upper surface perforated with small holes (according to the size required) is
keyed on to a revolving spindle or shaft, which table may revolve in a round or
other suitable casing being driven by a strap or rope by means of a wheel keyed
on the same shaft. This casing to the aforesaid revolving table is made in such a
manner that it allows of a free rotatory motion to the table, but with sufficient
nicety so as to prevent the material being operated on from falling through.
Underneath the table the casing is made to be in communication with an exhaust
fan which, drawing the air through the perforations, thus couls any material on
the revolving table. Hence, when the cooling operations are completed by taking
advantage of the rotatory motion of the table, it is only required to open a sluice
or door on the upper portion of the casing to allow of the material discharging
itself by its centrifugal force through this sluice into receivers or sacks therefor.

page_text: and these together with the cone O maintain a perfect distribution of the material
during its revolving. When it is found that the cooling has been effected the
sluice G is opened, and the material owing to its centrifugal action is instantly
discharged through this opening into sacks, thus completing what was originally
contemplated, namely, that it should be done automatically, without the assistance
of manual labour, being cheaper, quicker, and much cleaner than the methods
hitherto employed.
Having thus fully described the nature of the said Invention and the manner
of performing the same, we do not confine ourselves to the arrangements herein set
forth, nor do we limit ourselves to the details described above, as many alterations
or mechanical equivalents of effecting the same may be devised, but we wish it to
be understood that we claim,-
First. The use and employment of a revolving table for the purpose of cooling,
cleansing, and agitating the material, as herein set forth.
Secondly. The combination of distributing vanes and centre cone for equalising
the agitation of material.
Thirdly. The perforated table allowing the down draught of cooling air and exit
of dust and chaff during the process, all taking place simultaneously.
Fourthly. The final operation of discharging through the shoot the materials by
means of its centrifugal force established by the revolving table.
In witness whereof, we, the said Francis George Fleury and Edward Dunning
Barker, hereunto set our hand and seal, this Eighth day of April, in the
year of our Lord One thousand eight hundred and eighty.
