PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Washing and Separating Stones,
Mud, and other Impurities from Wheat and other Grain.
I, JAMES WALWORTH, of Longfield Villa, 130, Legrams Lane, Bradford in
the County of York, Milling Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention consists in employing an extra stoning arrangement, and also
facilitating the discharge of stones in what has been known as Cluderays Patent
Fountain Grain Washer No. 1909 of 1877 of which I am the sole proprietor.
To carry out my invention,
Firstly. I employ a similar water tight tank to the one mentioned in Cluderays
Specification, but in place of discharging the stones by the present method at the
head end of the machine 1 employ a conical valve constructed in such a manner
that by turning a hand wheel, or by an automatic motion the stones may be
discharged without loss of water, or stoppage of the machine, as has hitherto been
the case.
Secondly. At the extent of the vertical flow of water, I form horizontally, or at
a slight gradient, a partition, or plate of a suitable length, having at the end a
chamber passing down into the body of the machine for the reception of stones, etc.
At the bottom of this chamber, I place a worm conveyor for the purpose of con-
veying the stones, etc., into a suitable box fixed at the side of the machine. To the
bottom of this box I fix a similar valve to the one hereinbefore mentioned for the
discharge of stones, etc.
By this arrangement the water passing over the top of the chamber carries the
grain with it into the washing cylinder, but the centrifugal pump is so regulated
that the stones and other impurities being heavier than the grain, fall down to the
bottom of the chamber and from thence pass to the box at the side, by means
of the conveyor, where they are discharged through the valve.
Across the top of the chamber I may place strips of angle iron or its equivalent
from side to side of the machine, thus forming a series of openings, which allow
the stones, etc., which may have passed the first seperation, to fall into the chamber
below.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Washing and Separating Stones,
Mud, and other Impurities from Wheat and other Grain.
I JAMES WALWORTH of Longfield Villa, 130 Legrams Lane, Bradford, in the
County of York, Milling Engineer, 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 :—
This invention consists in employing an extra stoning arrangement, and also
facilitating the discharge of stones, in what has been known as Cluderay's Patent
Fountain Grain Washer No. 1909, of 1877, of which I am the sole proprietor.
To carry out my invention,
Firstly. I employ a similar water tight tank to the one mentioned in Cluderay's

page_text: Specification, but in place of discharging the stones by the present method, at the
head end of the machine, I employ a conical valve constructed in such a manner
that by turning a hand wheel, or by an automatic motion, the stones may be
discharged without loss of water or stoppage of the machine as has hitherto been
the case.
Secondly. At the extent of the vertical flow of water, I form horizontally or at
a slight gradient a partition, or plate of a suitable length having at the end a
chamber passing down into the body of the machine for the reception of stones, etc.
At the bottom of this chamber I place a worm-conveyor for the purpose of conveying
the stones, etc., into a suitable box fixed at the side of the machine.
To the bottom of this box I fix a similar valve to the one hereinbefore mentioned
for the discharge of stones, etc.
By this arrangement the water passing over the top of the chamber carries the
grain with it into the washing cylinder, but the centrifugal pump is so regulated
that the stones and other impurities being heavier than the grain, fall down to the
bottom of the chamber, and from thence pass to the box at the side, by means of
the conveyor, where they are discharged through the valve.
Across the top of the chamber I may place strips of angle iron or its equivalent
from side to side of the machine, thus forming a series of openings, which allow
stones, etc., which may have passed the first seperation to fall into the chamber
below.
In order that my invention may be fully understood, I will proceed to describe
the same with reference to the accompanying drawings, in which
Figure 1 represents a side elevation of Cluderays fountain grain washer, partly
in section showing my improvements.
Fig. 2. represents a cross section of the machine through the extra stoning
chamber.
Fig. 3. represents a plan of the plug of the outlet valve for stones.
Fig. 4. represents a cross section of the outlet valve for stones, and
Fig. 5. represents a front elevation of the receiving chamber for stones.
Similar letters refer to similar parts in each figure.
The grain or material to be washed is received by the hopper A. from whence
it passes down into the water between the partitions B. & C. where it is met by a
vertical current of water, this current (the course of which is shown by the arrows)
carries the grain upwards, and horizontally towards the washing cylinder D. but
the stones, mud, etc. being heavier than the grain fall into the receiving chamber E.
where they are discharged by means of the valve F. the plug of which is formed
with one, two or more recesses or pockets N. which receive the stones, etc. these
fall out by turning the hand wheel G. until the pocket N. is brought to the
opening R. at the bottom of the valve, at the same time placing another pocket in
position to receive a fresh supply of stones without loss of water or stoppage of the
machine.
The water in passing towards the washing cylinder D. carries the grain over the
grating H. and the stones which still remain in the grain fall through the grating
into the bottom of the chamber J. from whence they are conveyed to the box L.
by means of the worm K. which is caused to revolve by turning the handwheel O
attached to the end of the spindle.
At the bottom of the box L. I place a similar valve to the one hereinbefore
mentioned in connection with the receiving chamber E. for the discharge of
stones.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed, I declare that what I
claim is:
1st. In machines for washing and stoning grain, etc., the valve M. constructed in

page_text: 2nd. In machines known as Cluderays fountain grain washer, the extra stoning
chamber in combination with the receiving box L. constructed in the manner
described and represented in the accompanying drawings.
