Year: 1875

page_text: LETTERS PATENT to Charles Lucop, of Southwark, in the County of
Surrey, for the Invention of "IMPROVEMENTS IN MACHINERY FOR GRIND-
Ing and PulverIZING SEED, GRAIN, ORE, AND OTHER Substances."
Sealed the 6th July 1875, and dated the 20th April 1875.
PROVISIONAL SPECIFICATION left by the said Charles Lucop at
the Office of the Commissioners of Patents, with his Petition, on
the 20th April 1875.
I, CHARLES LUCOP, of Southwark, in the County of Surrey, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
FOR GRINDING AND PULVERIZING Seed, Grain, ORE, AND OTHER SUBSTANCES," to
be as follows:-
This Invention relates to new or improved machinery for grinding,
crushing, pulverizing, and reducing to powder various vegetable, mineral,
and animal substances, such as seed, grain, ores, lime, cement, black-
lead, plaster, colors, baryta, sulphur, glass, or other substances, which
according to my Invention is accomplished by means of centrifugal
force.

filed by the said Charles Lucop in the Great Seal Patent Office
on the 19th October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
Lucop, of Southwark, in the County of Surrey, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of April, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Charles Lucop, Her special 3
license, that I, the said Charles Lucop, my executors, admini-
strators, and assigns, or such others as I, the said Charles Lucop,
my executors, administrators, and assigns, should at any time agrec
with, and no others, from time to time and at all times thereafter

page_text: during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN MACHINERY FOR GRINDING AND PULVERIZING SEED, GRAIN, .
ORE, AND OTHER SUBSTANCES," upon the condition (amongst others) that
I, the said Charles Lucop, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Charles Lucop, do hereby declare
the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :—
This Invention relates to new or improved machinory for grinding,
crushing, pulverizing, and reducing to powder various vegetable, mineral,
and animal substances, such as seed, grain, ores, lime, cement, black-
lead, plaster, colors, baryta, sulphur, glass, or other substances, which
according to my Invention is accomplished by means of centrifugal
force.
Machinery arranged and combined in accordance with my Invention
is constructed as shewn by Figures 1 and 2 of the Drawings hercunto
annexed, with a circular metal or other casing a, a, of a flat, elliptical, or
other form, or it may be a long flat sided oblong, or other suitable form.
This casing a is fixed firmly on a bed plate a', a¹, or other secure
foundation. A shaft 6 passes through the centre, and has keyed upon
it arms c, c, to act upon a ball sphere or roller of metal or other material
(or a series of them) and when the shaft 6 revolves to say 300 revolu-
tions, more or less, per minute, the balls d or other bodies are carried
round by the arms c, c, by the centrifugal action, so as to fly off from
the centre and run on the interior periphery of the casing a, and thus
by centrifugal force crush, grind, and pulverize the substances they
come in contact with.
The sides of the casing may be perforated or formed as open wire
sieves of the required fineness stretched over openings c, c, and regu-

page_text: A series of brushes f, f, attached to and revolving with the central
shaft b, may be arranged to pass over the inner surface of the sieves
e, e, and thereby brush the material under treatment through as it is
pulverized.
If desired rotary motion may be given to the casing in an opposite {
direction to the arms.
For some purposes, when it is desired to reduce the substances treated
to a granular state only, I prevent the balls, spheres, or rollers & from
acting upon the inner circumference of the casing a by inserting bear-
ings or packings within the slots c¹ of the arms c in order to regulate
the distance to which the rollers are allowed to travel towards the inner
periphery of the casing a.
Having thus described the nature of my Invention, and the manner
of performing or carrying the same into practice, I would have it
understood that I do not limit my claim to the particular mechanical
arrangement herein-before described and represented in the Drawing
hereunto annexed, as the same may be greatly varied without departing
from the true character of my Invention, but what I claim is, the
improved arrangement and construction of machinery for grinding,
granulating, and pulverizing seed, grain, ore, and other substances by
centrifugal force, substantially in the manner herein-before described
and represented in the Drawings hereunto annexed.
In witness whereof, I, the said Charles Lucop, have hereunto
set my hand and seal, this Nineteenth day of October, in the
year of our Lord One thousand eight hundred and seventy-
five
