PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Husking or Cleaning Seeds.
I, JAMES CUMMING STEWART, of 4, East Broughton Place, Edinburgh, in the
County of Mid Lothian, North Britain, Seed Merchant, do hereby declare the
nature of this invention to be as follows, that is to say:―
My said invention has for its object the construction of improved apparatus for
husking or cleaning seeds in an expeditious, effective, and satisfactory manner.
My apparatus has been designed for separating the husks from the kernels of the
holcus seeds associated with New Zealand cocks foot; it is however also applicable
for treating other seeds.
In carrying out my invention I arrange in a suitable framing a drum or cylinder
having its shaft horizontal and made to rotate in any convenient way. The drum
is circumferentially covered with wire card or is otherwise armed with fine teeth.
On the descending side of the drum there is arranged a concave board, or
plate or a set of such boards or plates, the concave surface of which is covered
with wire card or is otherwise armed with fine teeth. The concave, board or plate
or set of boards or plates is adjustable so that it can be set in suitable proximity to
the drum, and a reciprocating motion is imparted to it by an adjustable rotating
crank, or cam, or other suitable mechanism. The seeds are fed from a hopper
above the drum, so as to enter between the drum and the reciprocating board or
plate or set of boards or plates, and on passing below the latter are subjected to
an air current from a blowing or suction fan. The materials pass on to a jigging
or concussion screen or sieve, and what passes through such screen or sieve pass
down on to a lower screen or sieve. The seeds passing through the lower screen
or sieve, are received in a box, the cocks-foot being delivered over the lower end
of the screen or sieve.

Improvements in Apparatus for Husking or Cleaning Seeds.
I, JAMES CUMMing Stewart, of 4 East Broughton Place, Edinburgh, in the
County of Mid Lothian, North Britain, Seed Merchant, 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, that is
to say :-
My said invention has for its object the construction of improved apparatus for
husking or cleaning seeds in an expeditious, effective, and satisfactory manner.
My apparatus has been designed for separating the husks from the kernels of the
holcus seeds associated with New Zealand cocksfoot; it is however also applicable
for treating other seeds.
In carrying out my invention I arrange in a suitable framing a rotating drum or
cylinder covered circumferentially with wire card, or otherwise armed with fine
teeth. On the descending side of the drum there is arranged an adjustable concave
board or plate or a set of such boards or plates the concave surface of which is
covered with wire card or is otherwise armed with fine teeth; and a reciprocating
motion is imparted to the board or plate by an adjustable rotating crank, or cam, or

enter between the drum, and the reciprocating board or plate, and on passing below
the latter are subjected to an air current produced by a blowing or suction fan.
The materials pass on to a jigging or concussion screen or sieve, and what passes
through such screen or sieve passes down onto a lower screen or sieve. The seeds
passing through the lower screen or sieve, are received in a box, the cocksfoot being
delivered over the lower end of the screen or sieve.
And in order that my said invention and the manner of performing the same may
be properly understood I hereunto append a sheet of explanatory drawings to be
hereinafter referred to and showing in sectional elevation a simple modification of
my improved apparatus for husking or cleaning seeds.
of
In carrying out my invention arrange in a framing, A, a drum or cylinder, B,
having its shaft, C, horizontal and made to rotate in any convenient way. The
drum, B, is circumferentially covered with wire card, D. On the descending side
of the drum, B, there arranged a concave board or plate, E, the concave surface
of which is covered with wire card, F. The concave board or plate, E, is connected
by short links, G, to screwed rods, H, passing-through-eyes-in-ths-ends
brackets, J, and adjustable by nuts, K, so that the board, E, can be set in suitably
promixity to the drum, B. A reciprocating motion is imparted to the board by an
adjustable rotating crank, L, acting on a projection, X, on the back of the board.
The seeds are fed from a hopper, M, above the drum, B, their passage being
regulated by an adjustable sliding shutter, N, and they enter down between the
drum and the reciprocating board, E, and on passing below the latter they are
subjected to an air current from a blowing fan, P, which current carries the husks
through an opening, Q, in the framing, A. Instead of the blowing fan, P, a
suction fan may be placed at or near the discharge opening, Q. The materials are
guided by a plate, R, onto a screen or sieve, S, to which a jigging motion is
imparted by a wiper, T, on a shaft driven by a belt from the fan shaft, and what
passes through such screen or sieve passes down onto a lower screen or sieve, U.
The seeds passing through the lower screen or sieve, U, are received in a box, V,
the cocksfoot being delivered over the lower end of the screen or sieve, U, and
discharged through an opening, W.
Instead of the links, G, being connected to screw rods, H, as hereinbefore
described they may be connected to blocks made adjustable in guides upon the
framing.
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 :
The construction, combination, and arrangement of parts constituting my
improved apparatus for busking or cleaning seeds substantially as hereinbefore
described and as shown on the accompanying drawings.
