Engineer.]
Improvements in Apparatus for Cleansing Wheat and other Grain.
I, OLIVER IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in the
County of London, Fellow of the Institute of Patent Agents, do hereby declare
the nature of this invention to be as follows :-
In the Specification No. 9419 of 1889 and No. 6792 of 1890 is 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 earthy impurities are collected in a chamber below the sieve. In order to
cause these impurities to travel continuously towards the well of the sieve through
which they are discharged, a number of slightly inclined blades are, according to
the present invention, placed under the sieve, so that each ascending pulse of the
water is directed somewhat towards the well and the impurities are thus moved
towards it. The impurities as they collect in the bottom of the apparatus, are,
according to the present invention, by means of an inclined worm or conveyor, or by
means of a horizontal worm or conveyor and an elevator or upright worm combined
therewith, raised above the water level and discharged automatically and continuously
while the apparatus is at work.
Dated this 21st day of July 1891.

Improvements in Apparatus for Cleansing Wheat and other Grain.
1, OLIVER IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in the
County of London, Fellow of the Institute of Patent Agents, 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 :-
In the Specifications No. 9419 of 1889 and No. 6792 of 1890 is 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 earthy impurities are collected in a chamber below the sieve. In order to
cause these impurities to travel continuously towards the well of the sieve through
which they are discharged, a number of slightly inclined blades are, according to
the present invention, placed under the sieve, so that each ascending pulse of the
water is directed somewhat towards the well and the impurities are thus moved
towards it. The impurities as they collect in the bottom of the apparatus, are,
according to the present invention, by means of an inclined worm or conveyor or by.
means of a horizontal worm or conveyor and an elevator or upright worm combined
therewith, raised above the water level and discharged automatically and continuously
while the apparatus is at work.
Figs. 1 and 2 of the accompanying drawings are vertical sections, on planes at
right angles to one another, of the cleansing apparatus shewing inclined blades A
placed, according to this invention, under the sieve B so that the pulses of water, as
they beat against the sieve, instead of being vertical, are directed by the inclination
of the blades A somewhat towards the well W which receives the impurities, the
travel of the impurities towards the well being thus promoted. At the bottom of
"

page_text: the well W the impurities are moved by a worm conveyor C to one side whence they
are raised by an elevator D to be delivered outside the apparatus.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In apparatus for cleansing wheat and other grain by the pulsating action of
water, in combination with the sieve, inclined blades under the sieve arranged to
direct the water pulses towards the well for receiving the impurities, substantially
as described.
