DISINTEGRATING OIL AND OTHER SEEDS."
"AN IMPROVED MACHINE FOR
My Invention relates to an 'improved machine for disintegrating seeds consisting
of two sets of radial arms rotating opposite or in front of one another within a flat
circular casing. The arms are furnished with projections or beaters on each face,
alternated with spaces, those on the adjacent faces of the two sets of arms being so
disposed that the projections on the one set shall pass through the spaces between
those on the other set. The arms radiate from bossess fixed on the ends of two shafts
which pass into the casing through bearings at the opposite sides thereof, the shafts
being in the same axial line. They are rapidly rotated in the same direction, but
at velocities differing in the proportion of 2 to 1, or in such other proportion as may
The casing is
be found most effective to disintegrate the kind of seed operated on.
provided with suitable inlet and outlet openings.
The seeds before being submitted to the action of the machine should be bruised
by being passed between iron rolls or otherwise.

page_text: My Invention relates to an improved machine for disintegrating seeds, consisting
of two sets of radial arms rotating opposite to or side by side with one another
within a flat circular casing. The arms are furnished with projections or beaters,
on each face alternated with spaces, those on the adjacent faces of the two sets of
arms being so disposed that the projections on the one set shall pass through the
spaces between those on the other set. The arms radiate from bosses fixed on the
ends of two shafts which pass into the casing through bearings at the opposite
sides thereof, the shafts being in the same axial line. They are rapidly rotated in
the same direction, but at varying velocities, in such proportions as may be
found most effective to disintegrate the kind of seed operated upon; the casing is
provided with suitable inlet and outlet openings.
The seeds before being submitted to the action of the machine should be bruised
or crushed by being passed between iron rolls or otherwise.
In order to enable my Invention to be better understood, I will proceed to
describe the same by reference to the accompanying Drawings, in which Figure 1 is
a section through my improved apparatus, which shows the radiating arms or
beaters and the radiating ratchet on the side of the casing.
Figure 2 is a plan of the apparatus.
Figure 3 is a modification of the radial arms or beaters; Figure 4 is a side view
he same.
Similar letters of reference are used in all the Figures to represent similar parts.
The casing of my apparatus is indicated by the letter A; the ratchet teeth B are
cast to and form part of A; the ratchets on the side plates at B¹ radiate to the
centre of the shafts C, C, which are mounted in journals D, D, and secured to the
brackets forming part of casting A; the radial arms or beaters E may be of various
forms, and accomplish the object of disintegrating the seed that has passed through
rollers or other apparatus for crushing the same, but while I prefer using the kind
shown on the Drawings I do not confine myself to the precise details as to the
form of the projections on the radial arms or the number on each arm, which may
be varied in proportion to the diameter of the arms. These arms or beaters may be
made of brass with renewable steel facings F or of phospor bronze, or any other
hard and tough metal that is suitable for revolving at a high velocity; the crushed
seeds are conveyed to the hopper G fixed on the top of my apparatus and run into
the inside of the casing A; the crushed particles of seeds are thus brought in
contact with the revolving radial arms or beaters E that are revolving at different
velocities, by which means the crushed seeds are broken up and disintegrated into
minute particles and delivered by the centrifugal force of the radial arms E into the
hopper H fixed near the top of the casing; the particles of seed having to pass
almost the entire circumference of the casing from the inlet G to the outlet H are
thoroughly disintegrated or reduced to a fine powder; the openings through the
casing A at J are for the purpose of admitting air within the casing, in order to
assist the radial arms to deliver the disintegrated seeds into the hopper H.
A modification of the radial arms or beaters is shown in Figures 3 and 4 with
single plain projections at the end, which may be fitted with steel facings as before
described.
Having thus described the nature of my Invention and the manner in which
the same is or may be performed, I have to state that I do not restrict myself to the
precise details herein described and delineated, as the form of the arms or beaters
may be considerably varied without departing from the characteristic nature of my
Invention; but that what I believe to be novel and original, and claim as the
Invention secured to me by the herein-before in part recited Letters Patent is,-
The employment of two sets of radial arms attached to separate shafts by means
of bosses; the shafts are in the same axial line and running in the same direction at
varying speeds within the casing already described.
The mode of inlet and outlet to and from the apparatus as shewn in Drawing.
And, the general arrangement or combination of the parts of the disintegrating

page_text: apparatus used in conjunction with each other, substantially as herein; described and
represented in the accompanying Drawing.
In witness whereof, I, the said Harrison Holt, have hereto set my hand and
seal, this Fourteenth day of August, in the year of our Lord One thousand
eight hundred and seventy-seven.
