"Seed" or other Substances.
I WILLIAM TOWL, the younger, of Marsh Gate Lane Stratford, in the county of
Essex Miller do hereby declare the nature of this invention to be as follows:-
The object of this invention is to separate the heavier and better qualities of grain
or cereals from the "seed," husk and other objectionable materials and to this end
the invention consists in the arrangement and combination of parts as hereinafter
described by which the desired result may be attained.
Upon suitable journals in the frame work is mounted a hollow cylinder provided
longitudinally with a series of perforations or openings through which the substances
and smaller grain can freely pass. Over the openings are a series of baffle plates
forming a species of external longitudinally slotted cylinder the slots in which are not
opposite to the perforations in the inner cylinder. The two cylinders are held a slight
distance apart by means of separating rings, set screws, or other suitable devices the
distance being adjusted according to the class of grain to be treated. The arrange-
ment of the various parts of the apparatus may be conveniently set forth by describing
the operation it being understood that the cylinders are slightly inclined from the
horizontal.
The grain is fed into the upper end of the perforated cylinder which is slowly
revolved the grain gradually travelling down it during which travel the "seed" and
smaller grains pass through the perforations and rest upon the baffle plates until
during their revolution the attraction of gravitation causes said "seed" and other
objectionable substances to fall through the slots or between the plates into a suitable
chamber adapted to receive them and from which they may be removed by a worm
screw or other means to a further chamber the lighter particles being eliminated
by means of an exhaust and the smaller grains and "seeds" left to form a second
quality."
«
The larger and longer grains are prevented from passing through the perforations
in the cylinder owing to their ends coming in contact with the baffle plates and they
continue to travel down said cylinder to its end where they are discharged into a
suitable receptacle and form a first quality or selection of the substance treated.

66 Seed" or other Substances.
I, WILLIAM TOWL the younger of Marsh Gate Lane Stratford in the County of
Essex, Miller, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
The object of this invention is to separate the heavier and better qualities of grain
or cereals from the smaller and from the "seed," husk and other objectionable
materials and to this end the invention consists in the arrangement and combination
of parts as hereinafter described by which the desired result may be attained.
Upon suitable journals in the frame work is mounted a hollow cylinder provided
longitudinally with a series of perforations or openings through which the substances
and smaller grain can freely pass. Over the openings are a series of battle plates
forming a species of external longitudinally slotted cylinder the slots in which are not
opposite to the perforations in the inner cylinder. The two cylinders are held a slight
distance apart by means of separating rings, set screws, or other suitable devices the
distance being adjusted according to the class of grain to be treated. The arrange-
ment of the various parts of the apparatus may be conveniently set forth by describing
the operation and for this purpose reference is made to the accompanying drawings in
which:-
Fig. 1 is an elevation of the screening cylinder employed for the purpose.
Fig. 2 is an end view of the same.
Fig. 3 is an enlarged section of a portion of the cylinder on the line x x Fig. 1.
Fig. 4 is a similar enlarged section of a portion of the cylinder on the line y y
Fig. 1, while
Fig. 5 shows said cylinder mounted in a suitable framework.
Upon a shaft B are mounted a number of wheels or rings C which support a sheet
metal cylinder A, having perforations a as shown in Fig. 1. Upon the outer surface
of the cylinder are mounted a corresponding number of metal rings D upon which
are placed curved baffle plates E, as shown in Fig. 1, where four are employed, one
being broken away to show the perforated cylinder beneath. The method of attaching
these plates E, to the cylinder is clearly represented in Figs. 3 and 4, where a clip d
is shown as holding down the plates by pressure upon angle iron strips e, which are
rivetted to them, the whole being secured to the cylinder by bolts b. The plates
are so arranged that a long slot or space f, is left between them, the portion of the
cylinder A, directly beneath being blank or unperforated to prevent the grain from
escaping. The operation of the cylinder is as follows, reference being had more
particularly to Fig. 5 where one is shown as mounted in a framework F, although
the arrangement of the particular machine employed may be varied as it will be
evident that a number may be mounted in one framework which may be of any
suitable description.

page_text: The grain fed from the hopper G, passes onto an inclined sieve which may be
shaken by any suitable means so as to cause the grain to fall through the same on to
the closed bottom i from whence it passes through the shoot I, into the cylinder A,
which is revolved by suitable means such as by the gearing shown at J. Stones and
other objectionable substances which cannot pass through sieve H, are caught in a
trough at the bottom thereof or are otherwise discharged to waste.
The grain gradually travels down the cylinder during which travel the "seed"
and smaller grains pass through the perforations a and rest upon the baffle plates E,
until the revolution of the cylinder causes said "seed" and other objectionable
substances to fall between the plates and through the openings f, into a suitable
chamber g, adapted to receive them and from which they may be removed by any
suitable means.
The larger and longer grains are prevented from passing through the perforations
owing to their ends coming in contact with the baffle plates and they continue
to travel down said cylinder to its end where they are discharged into a suitable
receptacle or shoot h, from which the dust and lighter particles are drawn by means
of a fan K, as shown. The baffle plates may be provided with handles 1, by which
they may be readily drawn out from one end after loosening the clips d, for the
purpose of cleaning or for clearing away any obstruction.

وف
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
1. The improvements in apparatus for separating grain or cereals from "seed
other substances, consisting of a perforated cylinder surrounded by baffle plates,
substantially as described.
or
or
2. The improvements in apparatus for separating grain or cereals from "seed"
other substances, consisting of the combination of the hopper or other feed with a
suitably mounted perforated cylinder, the latter being arranged to deliver the smaller
grain, waste and seed" into one receptacle while the larger and cleaned grain passes
out from the end into a second receptacle, and a suitable exhaust or blast by which
any lighter particles or dust are removed, all substantially as described.
