PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cleansing Wheat and other Grain.
I, HENRY SIMON, of No. 20 Mount Street, Manchester, in the County of
Lancaster, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
In the Specifications No. 9419 of 1889, No. 6792 of 1890 and No. 12,410
of 1891, I have described apparatus for cleansing wheat and other grain by
exposing it on a sieve to the pulsating action of water, whereby the grain is floated
over a tail board, while the stones, clay and other impurities are collected in
receptacles below the sieve from which they are removed. In these apparatus the
water is caused to pulsate by plungers reciprocating in chambers separate from
those in which the sieves with their depressions or wells are placed. The object
of my present invention is to simplify the machine and, when reciprocating
plungers are employed, to obtain their more direct action on the material on the
sieve or to dispense with such plungers.
When plungers are employed I place them in the same chambers with and under.
the sieve and well, and at the side of these chambers I provide in communication
with them a compensating chamber to allow for the movement of the water under
the plungers.
As the stones and impurities which pass through the mesh of the sieve and its
well fall on to the plungers, I make the upper faces of the plungers bevelled or
wedge shaped and leave room between the edges of the plungers and the walls of
the chambers so as to allow of the stones and impurities passing to the bottom,
whence they cau be-removed automatically, or otherwise..
The plungers may be driven as usual from overhead cranks or eccentrics and,
instead of two separate plungers, a single plunger may be employed to cause
pulsation over the whole sieve, including the well, suitable valves or checks being
employed to adjust the amount of pulsation at different parts. In some cases
dispense with plunger by imparting a vertically reciprocating motion to the sieve
itself including the well.

Improvements in Apparatus for Cleansing Wheat and other Grain.
1, HENRY SIMON, of No 20 Mount Street, Manchester, in the County of
Lancaster, Civil Engineer do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-.
tained in and by the following statement :-
In the Specifications No. 9419 of 1889, No. 6792 of 1890 and No. 12,410
of 1891, I have described apparatus for cleansing wheat and other grain by
exposing it on a sieve to the pulsating action of water, whereby the grain is floated
over a tail board, while the stones, clay and other impurities are collected in
receptacles below the sieve from, which they are removed. In these apparatus
the water is caused to pulsate by plungers reciprocating in chambers separate
from those in which the sieves with their depressions or wells are placed. The
object of my present invention is to simplify the machine obtaining with recipro-
cating plungers their more direct action on the material on the sieve or dispensing
with such plungers as I shall describe referring to the accompanying drawings.

page_text: Fig. 1 is a longitudinal section and Fig. 2 is a transverse section of one
arrangement of cleansing apparatus according to my present invention.
I place the plungers A, B in the same chambers with and under the sieve C and
well D, and at the side of these chambers I provide in communication with them a
compensating chamber E to allow for the movement of the water under the
plungers.
As the stones and impurities which pass through the mesh of the sieve and its
well fall on to the plungers, I make the upper faces of the plungers bevelled or
wedge shaped, as shewn at a Fig. 2, and leave room between the edges of the
plungers and the walls of the chambers, as shewn at b, so as to allow of the stones
and impurities passing to the bottom, whence they can be removed automatically,
or otherwise. The plungers A B are driven as usual from an overhead eccentric
(or it might be crank) F on shaft G, side rods H K extending down to the
plungers and at each side of the sieve and well respectively.
Fig. 3 is a longitudinal section and Fig. 4 is a transverse section of another
arrangement in which plungers are dispensed with. and a vertical reciprocating
motion is imparted to the sieve itself and to the well. For this purpose the sieve C
and the well D are suspended by side rods H from the eccentric F so as to receive
therefrom vertical reciprocating motion in the water contained in the tanks E
and E. By thus moving the sieve and well, I dispense with the plungers and also
with the compensating chamber. By connecting the well D to the sieve C, as
shewn in Figs. 5 and 6, I dispense with the separate forked rod for working
the well.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same to be performed, I declare that what I
claim is
1. In apparatus for cleansing wheat and other grain by the pulsating action of
water, arranging the plungers for causing pulsation under and in the same chambers
with the sieve and well respectively, substantially as described with reference to
Figs. 1 and 2.
2. Apparatus for cleansing wheat and other grain wherein the sieve and well are
made to reciprocate vertically in the water, substantially as described with reference
to Figs. 3 and 4 and Figs. 5 and 6.
Dated this 14th day of April 1893.
