I, WILLIAM PHILLIPS THOMPSON F.C.S. M.I.M.E. of the Agency for Foreign
Patent Solicitors 6, Lord Street, Liverpool and 6 Bank Street, Manchester both in
the County of Lancaster and 323 High Holborn in the County of Middlesex, Civil
Engineer do hereby declare the nature of this invention to be as follows:-
The roller threshing machine for colza, represented in the annexed drawings,
consists chiefly in the several pairs of rollers a, a, a, a, a, a, placed alongside each
other, and the rollers b, 61, which are provided with teeth, and placed over the
sieves c, c¹.
The rollers a, a, a", have ribs running lengthways 2 to 3 millimetres high, each
rib being made about 65 millimetres apart on the rollers a, 55 millimetres apart on
the rollers a¹, and 45 millimetres apart on the rollers a¹¹.
The upper rollers a, a¹, a¹¹, are mounted in the bearings a, and are capable of being
moved upwards, and pressed down by the spring y; the under rollers are mounted in
fixed bearings.
On the driving shaft d is the pulley e which is driven by a motor in the direction
indicated by the arrow, while the fixed drums f, f¹ on the same shaft drive the
rollers a, a, by means of straps, and the pulleys g and gl. The top rollers a¹, all receive
their rotation by spur wheels h, i, k, l, m, the bottom rollers a¹ all by wheels h³, 1 k¹,
,, while the toothed rollers 6, 6' are moved by wheels n, n¹ gearing with the spur
wheels i and 1. The strap running from f to g is crossed, while the one from f¹ to g¹
is not crossed, as shown in the side elevation represented in the drawings; the rollers
therefore revolve in the directions indicated by the arrows.
The action of the machine is as follows:-
The colza is introduced into the machine at A, passes through the rollers a, a, is
then immediately seized by the toothed roller b, which has a somewhat greater speed
than the rollers a¹, a", a¹", pressed on the sieve c, and brought to the set of

page_text: rollers a¹, a. After passing these, it is brought over the sieve c¹ by the toothed
roller b¹, and conducted to the rollers a", a¹¹, from whence the straw is discharged
at B.
In passing the first set of rollers, the greater part of the colza husks have been
broken up, the toothed roller b, which acts in a combing fashion, breaks up further,
part of the husks, and when the straw arrives at the rollers a¹, a', it is thoroughly
loosened. Here the same proceeding is repeated by the toothed roller ¹, and the
straw is here entirely cleared from seeds. Under the machine is suspended in the
joint pieces p, a shaking sieve 9. As shown in the drawing, this sieve obtains its
movement from the shaft r, and the pulleyss and t.
The seeds passing through the sieves e and c¹ mixed with broken husks and straw
fragments, fall on the shaking sieve, from which they fall sifted onto a sheet spread
underneath.

page_text: I, WILLIAM PHILLIPS THOMPSON F.C.S. M.I.M.E. of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street, Manchester, both in
the County of Lancaster, and 323 High Holborn, in the County of Middlesex, 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 ascertained in and by the
following statement:
The roller threshing machine for colza, represented in the drawings filed with the
provisional specification, consists essentially in the several pairs of rollers a, a,
a, a, a, a, placed alongside each other, and the rollers b, b', which are provided
with teeth, and placed over the sieves
c¹.
The rollers a, a, a", have ribs running lengthways 2 to 3 millimetres high, each
rib being made about 65 millimetros apart on the rollers a, 55 millimetres apart on
the rollers a¹, and 4 millimetres apart on the rollers a¹¹.
The upper rollers a, a', a¹¹, are mounted in bearings, and are capable of being
moved upwards, and are pressed down by springs y; the under rollers are mounted
in fixed bearings.
On the driving shaft d is the pulley e which is driven by a motor in the direction
indicated by the arrow, while the fixed drums f, f, on the same shaft drive the
rollers a, a, by means of straps, and the pulleys g and g¹. The top rollers a¹, a¹¹,
receive their rotation by spur wheels h, i, k, l, m, the bottom rollers a¹ all by
wheels h¹,, k, l, m, while the toothed rollers b, b, are moved by wheels n, n¹,
gearing with the spur wheels i and l. The strap running from f to g is crossed, while
the one from f¹ to g¹ is not crossed, as shown in the side elevation represented in the
drawings; the rollers therefore revolve in the directions indicated by the arrows.
The action of the machine is as follows:-
On passing through the first set of rollers, a great part of the colza husks are
opened; the toothed rollers b, which act like a rake or combing device, further open
the husks, and at the same time properly break up the straw, and bring it to the pair
of rollers a', a'. The action is again repeated by the toothed roller, and the straw
freed entirely from the seeds.
In passing the first set of rollers, the greater part of the colza husks have been
broken up, the toothed roller b, which acts in a combing fashion breaks up further
part of the husks, and when the straw arrives at the rollers a, a¹, it is thoroughly
loosened. Here the same proceeding is repeated by the toothed roller 61, and the
straw is here entirely cleared from seeds. Under the machine is suspended in the

page_text: joint pieces p, a shaking sieve q. As shown in the drawing, this sieve obtains its
movement from the shaft r, and the pulleys s and t.
The colza seeds fall through the sieves c, c¹, mixed with broken husks and haulms,
reach the shaking sieve through which they pass, and fall sifted in a clean state on a
sheet spread underneath.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
A machine for separating seed from colza, in which two toothed transporting
rollers 6, 6 revolving at a somewhat greater speed than the crushing rollers a, a,
a', a, a, a, between which they are placed, draw or drive the colza straw from one
set of crushing rollers to the next over the sieves c c¹ and simultaneously break
it up.
