PROVISIONAL SPECIFICATION.
A New or Improved Apparatus for Cleaning Clover and other similar
Seeds.
WILLIAM BONE 3 Sandon Terrace Harrowby Road, Grantham Lincs. Machine
Maker I do hereby declare the nature of this invention to be as follows :-
This invention has for its object the construction or arrangement of a new or
improved apparatus for cleaning clover seed & separating therefrom all other kinds
of seed, such as plantain & dock seed dross &c., in such a manner that the operation
is performed more conveniently speedily & effectually than is possible at the present
time with any other machine.
In carrying out this invention according to one modification of the new or
improved apparatus there is a flat screening surface composed of strips of wire, canvas
or cloth carried on narrow frames or laths, of wood or other suitable material; the
narrow frames are connected together in such a way as to form an endless band which
is carried on revolving rollers. The screening surface is inclined at a suitable angle
& is made to travel upwards. Besides the endless hand motion a reciprocating
motion is imparted to the screening surface. A brush of suitable material is
placed so as to bear against the screening surface, preferably underneath it, &
in such a way as to free the screening surface from any seeds dross &c. which
may have become embedded in it.
The working of the machine is as follows the uncleaned clover seed falls from a
hopper on to the upper end of the screening surface: the reciprocating motion
given to the screening surface causes the clover seed &c. to pass down over the
screening surface, the inesh of which is of such a size that clover seed cannot pass
thro' it the clover seed therefore travels down until it passes off the screening
surface at its lower end, perfectly clean; all other seeds & rubbish having either
fallen thro' the screen or being caught in the mesh of the screening surface have been
carried upwards, by reason of the endless band motion, & delivered at the upper
end of the screening surface away from the clover seed.
In another modification of this new or improved apparatus instead of the screening
surface being flat as described above, it may be placed on the periphery of two
cylinders; the arrangement of the apparatus in this case being as follows.
Two hollow cylinders of iron wood or other suitable material, are placed side by
side at an inclination i.e. having one end lower than the other.
Around the periphery of the cylinders is wrapped the screening material of wire
canvas cloth or other material the cylinders are geared to run in opposite directions
& are fixed to rotating spindles carried in a suitable frame.
In some cases only one cylinder may be found necessary.

A New or Improved Apparatus for Cleaning Clover and other similar
Seeds.
WILLIAM BONE 3 Sandon Terrace Harrowby Road, Grantham Machino Maker,
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 has for its object the construction or arrangement of a new or
improved apparatus for cleaning Clover seed and separating therefrom all other kinds

page_text: of seed such as plantain and dock seeds, dross &c. in such a manner that the opera-
tion is performed more coveniently speedily and effectually than is possible at the
present time with any other machine.
In carrying out the invention according to one modification of the new or improved
apparatus there is a fint screening surface A A composed of strips of wire, canvas
or cloth carried on narrow frames or laths, of wood or other suitable material. The
narrow frames are connected together in such a way as to form an endless band which
is carried on revolving rollers B B.
The aforesaid screening surface A A is inclined at a suitable angle and is made to
travel upwards. Besides this upward motion a reciprocating motion is imparted to
the screening surface A A. A Brush (of suitable material is placed so as to bear
against the screening surface, preferably underneath it and in such a way as to free
the screening surface from any seeds dross &c. which may have become embedded
in it.
The working of the machine is as follows, The uncleaned clover seed or linseed
falls from a hopper D through the riddles E and F on to the upper end of the
screening surface A A. The recipr. cating motion given to the screening surface
causes the clover seed to pass down over the screening surface A A the mesh of which
is of such a size that the seed to be cleaned cannot pass through it and therefore
travels down until it passes off the screening surface at its lower end at El perfectly
clean, all other seeds and rubbish having either fallen through the screening surface
or being caught in the mesh of the screening surface have been carried upwards, by
reason of the endless hand travelling motion imparted to it, and delivered at the upper
end of the screening surface at apart from the sood that has been cleaned.
In another modification of this new or improved apparatus instead of the screening
surface being flat as described above and shown in drawing, it may be placed on the
periphery of two cylinders the arrangement of the apparatus in this case being as
follows Two bollow cylinders of iron wood or other suitable material are plucod side
by side at an inclination .. having one end lower than the other; around the
periphery of each cylinder is wrapped the screening material of wire, canvas, cloth
or other material. The cylinders are geared to run in opposite directions & are
fixed to rotating spindles carried in a suitable frame-In some cases only one cylinder
may be found necessary.
Having now particularly described and ascertained the nature of any said Invention
and in what manner the same is be performed, I declare that what I claim is :-
No. 1. An improved screening surface working as an endless band for cleaning
Clover-seed and other similar seeds.
No. 2. A Brush underneath for cleaning the screening surface of the endless brand.
