page_text: LETTERS PATENT to James Walworth, of Bradford, in the County of York
Corn Mill Machine Maker, for the Invention of "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR WASHING OR CLEANSING AND DRYING EGYPTIAN
WHEAT, BEANS, AND OTHER KINDS OF GRAIN OR SEEDS."
Sealed the 11th September 1863, and dated the 14th March 1863.
PROVISIONAL SPECIFICATION left by the said James Walworth at the
Office of the Commissioners of Patents, with his Petition, on the 14th
March 1863.
I, JAMES WALWORTH, of Bradford, in the County of York, Corn Mill
Machine Maker, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN MACHINERY OR APPARATUS FOR WASHING OR CLEANSING AND
DRYING EGYPTIAN WHEAT, BEANS, AND OTHER KINDS OF GRAIN OR SEEDS," to be
as follows:-
The first part of this Invention consists of a cylindrical vessel having a
central rotary spindle therein, on which are a series of projecting arms. This
cylinder and spindle are by preference placed vertically. Also another cylinder
with a central rotary spindle having an archimedian screw thereon, which
cylinder is by preference placed at an inclination to the former cylinder, and
a channel or recess is formed longitudinally on the upper side of this inclined
cylinder. The two cylinders are connected by a spout or pipe at their bottom
ends. A hopper is placed above the vertical cylinder, from which the grain to
be washed is supplied or fed thereto, and an outlet spout is provided at the
top end of the inclined cylinder for the grain to pass out, also a pipe and tap
is introduced at the top of this cylinder for the supply of water, by which both

page_text: cylinders are kept full, and overflowing at or near the top of the vertical one;
and an outlet pipe and tap is provided at the bottom for the escape of water
and dirt. Motion is given to both the spindles by suitable gearing or pullies,
and straps or cords, so as to produce agitation of the grain in the vertical
cylinder, and cause the archimedian screw to raise the grain up the inclined
cylinder, from which it escapes at the top by the spout. An outlet is also
provided at the top of the vertical cylinder for chaff or light dirt to float off;
and there is also a perforated false bottom placed in the inclined cylinder to
prevent the grain from passing out by the dirt pipe.
The second part of this Invention consists of a vertical hollow spindle
capable of rotating, having a series of hollow circular tables attached thereto
and communicating therewith. Also, a series of scrapers are placed in contact
with the upper surface of each table at tangents thereto. Steam is supplied to
the hollow spindle at the top, and condensed water is let out at the bottom.
Grain, after being washed as set forth in the first part, is conducted by a hopper
or dish to the centre of the uppermost table, and is gradually pushed outward
by the scrapers off the edge as the spindle and tables rotate, whence it falls
into another dish or hopper, which conducts it to the centre of the second
table, where it is again driven gradually outward by the scrapers to and off
the edge to the next table, and so on from one table to another, when it finally
passes out at the bottom dried.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Walworth in the Great Seal Patent Office on the
14th September 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
WALWORTH, of Bradford, in the County of York, Corn Mill Machine Maker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said James Walworth, Her special license that I, the said James
Walworth, my executors, administrators, and assigns, or such others as I, the
said James Walworth, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter

page_text: daring the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR WASHING OR CLEANSING AND DRYING EGYPTIAN
WHEAT, BEANS, AND OTHER KINDS OF GRAIN OR SEEDS," upon the condition,
amongst others, that I, the said James Walworth, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Walworth, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, and the accompanying Sheets of Drawings, that is to say:-
The first part of this Invention consists of a cylindrical vessel having a
central rotary spindle therein, on, which are a series of projecting arms. This
cylinder and spindle are by preference placed vertically. Also another cylinder
with a central rotary spindle, having an archimedean screw thereon, which
cylinder is by preference placed at an inclination to the former cylinder, and a
channel or recess is formed longitudinally on the upper side of this inclined
cylinder. The two cylinders are connected by a spout or pipe at their bottom
ends. A hopper is placed above the vertical cylinder, from which the grain to be
washed is supplied or fed thereto, and an outlet spout is provided at the top
end of the inclined cylinder for the grain to pass out. Also, a pipe and tap
is introduced at the top of this cylinder for the supply of water, by which both
cylinders are kept full, and overflowing at near the top of the vertical one, and
an outlet pipe and tap is provided at the bottom for the escape of water and
dirt. Motion is given to both the spindles by suitable gearing or pullies, and
straps or cords, so as to produce agitation of the grain in the vertical cylinder,
and cause the archimedean screw to raise the grain up the inclined cylinder,
from which it escapes at the top by the spout. An outlet is also provided at
the top of the vertical cylinder for chaff or light dirt to float off, and there is
also a perforated false bottom placed in the inclined cylinder to prevent the
grain from passing out by the dirt pipe.
The second part of this Invention consists of a vertical hollow. spindle capable
of rotating, having a series of hollow circular tables attached thereto and coni-
municating therewith. Also, a series of scrapers are placed in contact with
the upper surface of each table at tangents thereto. Steam is supplied to the

page_text: hollow spindle at the top, and condensed water is let out at the bottom. Grain,
after being washed as set forth in the first part, is conducted by a hopper or
dish to the centre of the uppermost table, and is gradually pushed outward
by the scrapers off the edge as the spindle and tables rotate, whence it falls
into another dish or hopper, which conducts it to the centre of the second
table, where it is again driven gradually outward by the scrapers to and off the
edge to the next table, and so on from one table to another, when it finally
passes out at the bottom dried.
In order that this Invention may be clearly understood I have given refer-
ence to two accompanying Sheets of Drawings.
Fig. 1, Sheet 1, represents a sectional elevation of the apparatus for
washing or cleansing grain.
A is the vertical cylinder; B, the spindle, on which are a series of arms c,
which are shewn in plan at Fig. 2; D is the inclined cylinder with its spindle
and archimedean screw E. The two cylinders are joined together by pipes F
and G. Each cylinder has a perforated false bottom H and I, which are also
connected by a piece J through the pipe G. The two spindles are coupled
so as to be driven simultaneously by a strap K, and pullies L, M, fixed on
short shafts on the top of each cylinder gearing with the spindles; N is the
main driving pulley, and O the strap. Grain to be washed is supplied at the
spout P, and water at the tap Q, which fills up both cylinders to the level of
the overflow spout R. When motion is given to the spindles in the proper
direction, the grain is agitated in the water of the vertical cylinder by the
arms C, and thereby washed, from whence it passes out at the pipe G to the
bottom of the inclined cylinder, where the archimedean screw gradually raises
it up through the water therein, which is supplied. clear near the top, when it
finally passes out at the spout S, the top part of the archimedean screw being
perforated to let the water pass through. The taps T, U, are to draw off the
dirty water.
Figs. 3 and 4 are plan and edge views of another form of agitating arms,
shewing also two sets of spindles and arms working together in one cylinder.
The chaff and light grain and dirt floats off at the overflow spout.
The second part of my Invention will be readily understood by reference to
Sheet 2 of the Drawings, where Fig. 1 is an elevation partly in section of the
machine or apparatus for drying grain; and Fig. 2 is a sectional plan taken
through the line A, B, in Fig. 1. C is the vertical hollow spindle, supported
in bearings at the top and bottom, and motion given to it by gearing C
and driving shaft C near the bottom; D are the hollow circular tables, the
top table D¹ being shewn in section, as also a portion of the spindle. These

page_text: tables are attached to the spindle by screw nuts, and communication therewith
by small holes in the spindle; E, are the scrapers which are fixed by
adjusting screw nuts to bars F, attached to the pillars G, which form the
supports or framing of the apparatus; H´is the inlet tap or cock for steam;
and I the outlet for condensed water. Grain to be dryed is supplied from
the hopper or spout J to the centre of the uppermost table, which by the
rotation of the spindle and tables is carried round into contact with
scraper No. 1, which removes it a short distance from the centre, when, on the
table again coming round, that grain is brought into contact with scraper No. 2,
and so on to each scraper in succession until driven off the edge of the table
into the spout K, which conducts it to the centre of the next table, when, as
the spindle rotates, the grain is again brought in contact with each scraper in
succession until driven off the edge of the table into the spout L, which again
conducts it to the centre of the next table, from which it is gradually removed
as before into the spout M, which conducts it to a "separator" or two wire
netting sheets N, O, fixed in a frame, which has a shaking motion imparted to
it by means of connecting rod and a crank P fixed on a shaft Q, receiving
motion by gear R from the driving shaft C². The netting is of such gauge
as to take out small grain and weed seeds. The grain passing thence by the
spout S dried. This apparatus may be so placed in relation to the first part
of my Invention or washing machine, that the grain when discharged from the
said washing machine may be conducted by the spout to the drying machine,
and thereby the two machines may be caused to operate continuously together
as one machine, or each may be employed separately.
Having thus described the nature of my said Invention, and the manner in
which the same is or may be performed or put in practice, I would have it
distinctly understood that I do not confine myself to the precise details as
herein set forth, but what I claim is, apparatus for washing and drying grain,
constructed and arranged substantially as herein described and shewn in the
Drawings, either separately or combined.
In witness whereof, I, the said James Walworth, have hereunto set my
hand and seal, this Twelfth day of September, One thousand eight
hundred and sixty-three.
JAMES WALWORTH. (L.S.)
