page_text: LETTERS PATENT to Alister Gilian Fraser, George Smith, and Lewis Walter
Harvey, all of 33, Chancery Lane, in the County of Middlesex, for an
Invention of IMPROVEMENTS IN MACHINERY FOR SHELLING, CLEANING,
AND POLISHING RICE, COFFEE, AND OTHER GRAINS, BERRIES, AND SEEDS."
"
PROVISIONAL SPECIFICATION left by the said Alister Gilian Fraser, George
Smith, & Lewis Walter Harvey at the Office of the Commissioners of Patents
on the 6th October 1881.
ALISTER GILIAN FRASER, GEORGE SMITH, and LEWIS WALTER HARVEY, all of
33, Chancery Lane, in the County of Middlesex. "IMPROVEMENTS IN MACHINERY
FOR SHELLING, CLEANING, AND POLISHING RICE, COFFEE, AND OTHER GRAINS,
BERRIES, AND SEEDS."
This Invention particularly refers to that class of machine wherein a cone or
drum is caused to rotate within a hollowed cone or drum, or vice versa. Heretofore
one of the opposed or rubbing surfaces of the cones or drums has been provided
with india rubber, cork, sheep skin, wash leather, or equivalent materials, and the
other cone or drum coated with stone, or stony substances or compositions.
Now according to this present Invention we make one or both of the opposed or
rubbing surfaces of the cones or drums of a combination of materials, and preferably
of wood and leather. The leather is cut or formed into strips, and between each
two strips there is a layer of wood, the alternate strips of wood and leather are
secured together by glue or other convenient means; the leather strips or surfaces
project slightly beyond the wood surfaces, whereby there are furrows or spaces
formed between the leather surface, or at least this is the case until the surfaces
wear down flush, or nearly so; one of the conical or rubbing surfaces of the cones
or drums is or may be composed of a composition of emery, or of artificial or
natural stone, and the other or opposed surface of the combination of materials as

page_text: aforesaid, or the conical or rubbing surfaces of the cones or drums are lined with
surfaces made in the manner aforesaid; when worn, they can be renewed or repaired
wholly or partially as may be required.
Cones and concaves made and constructed according to our Invention can with
facility be fitted to the driving gear now generally in use with the ordinary known
shelling stone gear.
The Invention further consists in the application to and the employment in such
machines for shelling, cleaning, and polishing, of a worm wheel on the cone driving
spindle, into which worm wheel a tooth wheel gears, but at the same time any
other known means for driving the machine may, according to circumstances, be
used.

by the said Alister Gilian Fraser, George Smith, & Lewis Walter Harvey
in the Great Seal Patent Office on the 6th April 1882.
ALISTER GILIAN FRASER, GEORGE SMITH, and LEWIS WALTER HARVEY, all of
33, Chancery Lane, in the County of Middlesex. "IMPROVEMENTS IN MACHINERY

BERRIES, AND SEEDS."
This Invention refers to that class of machine wherein opposing surfaces, such,
for instance, as those of a cone or drum revolving within another cone or drum, are
employed for shelling, cleaning, polishing, or decorticating rice, grain, seeds, or
berries. Heretofore one of the opposed or rubbing surfaces has been provided with
india rubber, cork, sheepskin, wash leather, or other materials, and the other
surface has been made of or coated with stone, or stony substances or composition.
Now according to this present Invention we make one or both of the opposed or
rubbing surfaces of a combination of materials, and preferably of wood and leather.
The leather or other suitable material is cut or formed into strips, and between
each two strips there is a layer of wood or other suitable material; the alternate
strips, say, of leather project slightly beyond the wood surfaces, whereby there
are furrows or spaces formed between the leather surfaces, or at least this is
the case until the surfaces wear down flush or nearly so; one of the rubbing
surfaces is or may be composed of a composition of emery or of artificial or natural
stone, and the other or opposed surface of the combination of materials, as aforesaid,
or both the opposed surfaces are lined with materials inade in the manner
aforesaid; when worn they can be renewed or repaired wholly or partially as may
be required.
The combination of wood and leather constructed according to our Invention
can with facility be applied to such machines as are at present in use for shelling,
cleaning, polishing, or decorticating rice, grains, seeds, and berries.
The accompanying Drawings illustrate the manner in which we carry our
Invention into effect. Figure 1 is a plan, and Figure 2 a section of a portion of
the rubbing surfaces constructed in the manner beforo described; a represents the
leather strips, and 6 the wood strips.
Having now described the nature of our said Invention, and in what manner
the same is to be performed, we declare that we claim as our improvements in
machinery for shelling, cleaning, and polishing rice, coffee, and other grains, berries,
and seeds,
Making or composing one or both of the rubbing surfaces in such machines of
strips or pieces of material, such as leather, alternately with other strips or pieces
of material, such as wood, the leather or corresponding strips projecting somewhat
beyond the wood or corresponding strips, all substantially as and for the purposes
set forth.
In witness whereof, we, the said Alister Gilian Fraser, George Smith, and
Lewis Walter Harvey have hereunto set our hands and seals. this Third
ALISTER G. FRASER. (LS.)
