IMPROVEMENTS IN APPARATUS FOR DISIN- TEGRATING AND DRESSING CRUSHED OR BRUISED GRAIN OR SEED
Year: 1879

page_text: LETTERS PATENT to William Anfield, of Great Driffield, in the County of York,
Millwright, for the Invention of "IMPROVEMENTS IN APPARATUS FOR DISIN-
TEGRATING AND DRESSING CRUSHED OR BRUISED GRAIN OR SEED."
Sealed the 23rd March 1880, and dated the 7th October 1879.
PROVISIONAL SPECIFICATION left by the said William Anfield at the Office
of the Commissioners of Patents on the 7th October 1879.
WILLIAM ANFIELD, of Great Driffield, in the County of York, Millwright.
"IMPROVEMENTS IN APPARATUS FOR DISINTEGRATING AND DRESSING CRUSHED OR
BRUISED GRAIN OR SEED."
My Invention relates to apparatus for disintegrating and dressing crushed or
bruised grain or seeds, that is to say, breaking them up into a pulverulent condition
and effecting more or less separation of the husks from the meal or flour. The
apparatus is applicable to corn that has been crushed or bruised between rollers or
by being coarsely ground between stones, or to oleaginous seed, such as cotton seed,
that has been crushed or bruised.
I employ for the purpose of my Invention a double cylindrical screen, the inner
one being a wire cage and the outer a cage of wire, silk, or other porous fabric,
according to the character of the material treated and the degree of fineness desired
in the flour or meal to be produced. For example, for treating corn to separate fine
flour, silk is employed for the outer screen; for treating cotton seed to separate the
meal along with the finer portions of husk, the outer screen is of wire. The two
screens are caused to rotate in the same direction on an inclined axis, the inner
screen being made to revolve more rapidly than the outer screen. The crushed or
bruised material is fed from a hopper at the higher end into the annular space
between the two screens, and travels along that space subject to the action resulting
from the differential velocity of the two screens. By this action the crushed or
braised grains or seeds are disintegrated, and the finer particles are driven through
the pores or perforations of the outer screen into an outer casing, whence they are
led away by a spout, whilst the husks or the coarser portions thereof are discharged
from the lower end of the screens into a shoot, by which they are led away to be
ground, or otherwise treated in the usual way.

"IMPROVEMENTS IN APPARATUS FOR DISINTEGRATING AND DRESSING CRUSHED OR
BRUISED GRAIN OR SEED."
My Invention relates to apparatus for disintegrating and dressing crushed or
bruised grain or seeds, that is to say, breaking them up into a pulverulent condition
and effecting more or less separation of the husks from the meal or flour. The
apparatus is applicable to corn that has been crushed or bruised between rollers or
by being coarsely ground between stones, or to oleaginous seed, such as cotton seed,
that has been crushed or bruised.
I employ for the purpose of my Invention a double cylindrical screen, the inner
one being a wire cage and the outer a cage of wire, silk, or other porous fabric,
according to the character of the material treated and the degree of fineness desired
in the flour or meal to be produced. For example, for treating corn to separate fine
flour, silk is employed for the outer screen; for treating cotton seed to separate the
meal along with the finer portions of husk, the outer screen is of wire. The two
screens are caused to rotate in the same direction on an inclined axis, the inner
screen being made to revolve more rapidly than the outer screen.
The crushed or
bruised material is fed from a hopper at the higher end into the annular space
between the two screens, and travels along that space subject to the action resulting
from the differential velocity of the two screens. By this action the crushed or
bruised grains or seeds are disintegrated, and the finer particles are driven through
the pores or perforations of the outer screen into an outer casing, whence they are
led away by a spout, whilst the husks or the coarser portions thereof are discharged
from the lower end of the screens into a shoot, by which they are led away to be
ground, or otherwise treated in the usual way.
The accompanying Drawing represents a longitudinal section of disintegrating
and dressing apparatus according to my Invention. On an inclined shaft S, which
is driven at a considerable velocity by a band on a pulley s or otherwise, is fixed a
cylindrical screen D, closed at the ends and covered with wire gauze. Outside of
this is the outer screen K, which has a central opening in its front end at k, and has
also openings ke' near its circumference at its back end. The ends of this outer
screen are made with trunnions k³, which revolve in sockets fixed to the framing of
the apparatus; it is driven by gearing from the shaft S in the same direction, but
at a much slower speed. The gearing for this purpose may be varied; as shewn in
the Drawing, it consists of a small pulley a¹ on the shaft S, driving by a band a
larger pulley T beyond, this pulley carrying a pinion t, which gearing with a wheel u
drives a countershaft U, and a pinion v on the countershaft gears with teeth V on
the end of the outer screen. The substance to be operated on is fed from a hopper
into the space at the front of the casing, whence it passes by the aperture A into
space in this space it is struck by a number of pins or tines C projecting
from the end of the inner screen, and thrown violently against the outer screen,
whereby some of the finer particles are caused to pass through the meshes of the
outer screen. The material continues it course along the annular space between
the screens, subject to a similar action; and, finally, the husks and larger particles
issue by the apertures into the space G, whence they are led away. The fine
particles that pass through the outer screen are received in the hopper space E,
whence they pass by a spout F.

is to be performed, I claim,―
The use for disintegrating and dressing crushed or bruised grain or seed of
apparatus constructed and operating substantially as herein described with reference
to the accompanying Drawing.
In witness whereof, I, the said William Anfield, have hereunto set my hand
and seal, this Fifth day of April, in the year of our Lord One thousand
eight hundred and eighty.
