Apparatus chereror.
I, JOHN IRELAND BOOKER, Superintendent of the Boundary Engineering Company
Limited Boundary Street, Liverpool, in the County of Lancaster do hereby declare
the nature of this invention to be as follows:-
In cleaning and rinsing washed wheat or beans in the present machines, the present
types of wheat and bean washers are constructed as follows;
The present washer is a worm with a small part of its periphery running in water,
with a wire covering bolted round same, within which the grain passes, turning the
grain over in its passage, and rinsing it in a small amount of water.
The said worm and wire covering are one and the same article, fixed securely to
each other, and cannot move independently of each other.
1st. It does not wash the wheat sufficiently.
2nd. The casing gets choked up, and is very difficult to clean out.
3rd. The rinsing part of same is not perfect.
My invention is designed to perform these clearing operations while the machine is
at work, and also to increase the better washing of the wheat, to enable the wire
covering to be easily cleaned inside, and to increase the efficiency of the rinsing of
the grain.
The invention consists chiefly, first in an arrangement of mechanism by which the
worm revolves separately and independently of the wire cylinder, the wire cylinder
also revolving, but at a different speed.
Second, in placing a worm in the inlet for feeding the grain or seeds.
Third, in placing a worm in the outlet for discharging the grain.
Fourth, in the general arrangement of the machine.
Fifth, in introducing the washing water into a grain or seed washer, by means of an
injector pump or steam jet preferably through the centre of the worm shaft, and
Sixth, the system or process of washing as hereafter described.
The machine which I have designed is formed with a wire casing or cylinder
partially submerged in a tank of water, and revolving on a horizontal or slightly
inclined axis.

page_text: The end or continuation of the cylinder is conical to allow the grain to be carried
out of the water to the outlet, further with a worm or worms travelling at the same
or a different speed in reference to the wire casing, but with its or their travelling
contour nearly or quite filling the wire casing and driven independently of the same."
The feed and exit worms can be either fixed to the same shaft as the main worm, or
on sleeves revolving upon the same independently.
The water for washing purposes is preferably forced in by an injector through a
central channel in the main shaft, and out through perforations in the same, near the
exit end or conical part of the casing.
The worms can be formed of paddle blades or continuous screw threads as preferred.
The wire casing or cylinder for convenience of manufacture is preferably formed in
two halves bolted together parallel to the axis of the shaft carrying the same.
The grain is fed in a regulated stream into the revolving cylinder and is thoroughly
stirred up and washed by the revolution of the latter and by the worm. As it rides
up the conical part of the casing it is further washed with the fresh warm water
escaping from the hollow shaft. As it rises still higher it is drained and finally is
drawn out of the machine by the exit worm. The whole process is continuous.
Dated this 18th day of June 1886.

COMPLETE SPECIFICATION.
Improvements in Cleaning or Washing Grain or other Seeds and in
Apparatus therefor.
I, JOHN IRELAND BOOKER, Superintendent of the Boundary Engineering Company
Limited, Boundary Street, Liverpool, in the County of Lancaster, do hereby declare
the nature of this invention and in what manner the same is to be performed, to he
particularly described and ascertained in and by the following statement :-
This invention has for its objects certain improvements as hereinafter described in
cleaning or washing grain or other seeds, and in an apparatus therefor. In cleaning,
rinsing, or washing wheat, the present type of wheat and bean washers have hitherto
heen constructed with a worm, surrounded by a wire covering, within which the grain
passes. A small part of the periphery of the worm runs in water and the action
of the worm is to turn the grain over in its passage through the machine, and at
the same time to rinse it in a small amount of water. The said worm and wire
coverings are fixed securely to each other, and cannot move independently. Hence it
is found the wheat is not washed sufficiently, the casing gets choked up, and is very
difficult to clean out, and the operation of rinsing is imperfect.
My invention is designed to prevent the casing from being choked up, to insure the
better washing of the wheat, to enable the wire covering to be easily cleaned, and to
increase the efficiency of the rinsing of the grain.
My improvements consist chiefly, first in an arrangement of mechanism by which
the worm revolves separately and independently of the wire cylinder, the wire cylinder
also revolving but at a different speed; secondly, in placing a worm in the inlet for
feeding the grain or seeds; thirdly, in placing a worin at the outlet for discharging
the grain; fourthly, in the general arrangement of the machine; fifthly in introducing
the water into a grain or seed washer by means of an injector pump or steam jet,
preferably through the centre of the worm shaft, and sixthly, the system or process of
washing as hereafter described.
Referring to the drawings annexed hereto :-
Figure 1 is a sectional elevation of my improved machine.
Figure 2 is a plan, with top removed.
Figure 3 is an end elevation.
In these A is the driving shaft revolving in suitable bearings a, which are fitted in
brackets attached to the tank B, and provided with a driving pulley a². This tank is
constructed to hold a supply of water, and is fitted with a valve b to draw off the water
when required. C is a wire casing or cylinder inade in halves, partially submerged in
the water contained in the tank B. The two halves of the casing may be fastened
together at the centre by any suitable means so that one half may be easily removable,
for the purpose of cleaning the inside or of repairing or removing the worm c¹² or
beaters chereafter described. Although I prefer to make the casing in two halves I
do not limit the invention thereto.

page_text: The casing is constructed to revolve independently of the shaft A, and is supplied
with suitable bearings b formed in the tank B. The casing is fitted with wheels D
which gear with the wheel D' fixed on the shaft E. This shaft may be driven by the
belt pulleys F, F. On the same shaft E is fitted a brush E' which brushes against
the surface of the wire casing C and prevents the casing being choked. On the
surface of the shaft A, inside the wire cylinder C, I form a worm e¹, the blades of
which may be extended so as to form paddles or beaters c², or a continuous screw
thread may be used if preferred, and on the ends of the shaft A, the worm is extended
to form the feed and exit worms c³, c. They may either be fixed to the same shaft as
the main worm, or on sleeves revolving on the same, independently. The water for
washing purposes is preferably forced in by an injector H through a central channel
in the main shaft A, and out through perforations in the same, as shewn at near the
exit end or conical part of the casing. A pump, preferably a centrifugal one, may be
placed on the side of the tank B, for the purpose of drawing off the water in the said
tank, and forcing it in a spray on to the upper side of the wire casing or cylinder C,
or the water may be utilized in other ways, for instance in a stoning machine. The
height of the water in the wire casing C may be regulated from 1 to 8 inches.
In the old machines the height can only be regulated from 1 to 2 inches. The whole
machine may be fixed on suitable frames L.
The action of my machine is as follows: The grain is fed into the machine through
the hopper K by means of the feed worm c³. As the beaters e revolve at a different
speed from the wire casing C the grain is thoroughly stirred up and washed in the
hot water supplied by the injector H. The action of the beaters will be also to feed
the grain towards the conical end of the wire casing C which is not submerged in
water. It now comes in contact with the fresh warm water flowing through the
ets h. As it rises still higher it is drained by means of perforations into a vessel
or rinsing box M from whence the drainings are carried away by the pipe m, and finally
is drawn out of the machine by the exit worm through the exit spout N. The
whole process is continuous.
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
11
1st. An apparatus for washing or cleaning grain or other seeds in which a worm,
with or without beaters, or a series of beaters, paddles, or vanes, revolves in a wire or
perforated cylinder also revolving but at a different speed or direction from that of
the worm, substantially as described.
2nd. In an apparatus for washing grain such as described, a worm for feeding at
the inlet, and also a worm for discharging at the outlet, each in a cylinder or channel
smaller in radius than that containing the main worm.
3rd. The use in a grain or seed washer of an injector pump or steam jet, injecting
water into the mechanism through or along the worm shaft for the
described.
purposes
4th. In an apparatus for cleaning or washing grain or other seed having a worm or
screw such as described, the use of a wire case divided in the centre so that one half
