PROVISIONAL SPECIFICATION.
A Machine for Cleaning and Separating Cockle, Poppy, and other
Seeds and Grain of All Kinds from each other.
CHARLES KNOTT GRAHAM, Engineer of 85 London Wall E.C. and VLADIMIR
(son of Leonti) GALOCHKIN Engineer of Rostoff on Don, Russia, do hereby
declare the nature of this invention to be as follows:-
The peculiar shape given to cells, indents, or cups, & mode of operating same.
The machine is supplied with plates of metal, or other substance, formed into
cylinders having on their working surface indentations, cups, or cells, which when
in motion receive, separate, and remove, the different grains or seeds as desired. In
order to give a lateral movement a cam is employed, the movement consisting of a
to & fro motion. The peculiar shape of indentation referred to, consists of a cone
of irregular shape, the base being round but the top or apex being a semisphere the
centre of which (supposing the cone to be standing on its base, on a level place)
would be plumb with one point at the circumference of the base instead of with the
centre as in the ordinary cone. A plane passing by this line & through the centre
of the base of the cone would give a section not unlike that of an ordinary elevator
cup, it is in this plane & bearing always the same relative position to it that the
cell is made to do its work.

CHARLES KNOTT GRAHAM Engineer of 85 London Wall London and
VLADIMIR (son of Leonti) GALOCHKIN Engineer of Rostoff-on-Don, Russia, 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 :-
A metal cylinder (zinc by preference) with indents or cells on the inside, and
metal frame at each end, revolves round a shaft, the shaft is placed at an angle and
supported at each end. The indents receive the grain to be separated, which is
elevated by the rotation of the cylinder and falls into a tray suspended within the
cylinder by hangers from the shaft.
The invention claimed is. The shape given to the indents; the imparting of a
to and fro motion producing a series of oscillation or shocks both to the cylinder,
the tray, and to the grain which is being operated upon; the adjustable tray, and
mechanical methods of obtaining the results as here set forth.
The Shape of the Indents. This resembles a cone of irregular shape the base
being round and the top or apex being a semisphere or segment of a sphere the
centre of which supposing the cone to be standing on its base on a level plane
would be plump with one point at the circumference of the base instead of with the
centre of the base as with the ordinary cone; a plane passing through this plumb
line and through the centre of the base of the cone will give a section not unlike
that of an ordinary elevator cup.

page_text: Sheet I. Fig. I A. shows where the indents are all over the inside of the
cylinder, and their relative position when at work.
Sheet I. Fig. II A. shews these indents in the same relative position, and in
section. The indents drawn are those actually used for extracting cockle seed
from wheat and they are drawn at enlarged scale of two inches to an inch Sheet 1.
Fig. IIA. In treating various seeds the diameter of the base and depth of the
indent employed vary according to the relative diameters and lengths of the grains
requiring separation, their shape as described remaining the same. The imparting
of a to-and-fro motion producing a series of oscillations or shocks both to the
cylinder the tray and to the grain which is being operated upon.
To the shaft B (Sheet I Fig. 1. and elsewhere) is fixed a jawed chuck C (Sheet I.
Fig. 1 and 3).
The frame D (Sheet I Fig. 1. Sheet II. Fig. 6 and 7) is furnished also with a
corresponding chuck at the part where it comes in contact with C. This frame D
is attached to one end of the cylinder and revolves with it when the belt E. is put
in motion as shewn (Sheet I Fig. 1).
The frame D has for bearing a part of the combination banger F. This
hanger F. (Sheet I Fig. 1 Sheet II Fig. 9) can slide right and left on the shaft B.
but cannot revolve on it, being governed by two keys let into the shaft corre-
sponding to keyways in F. (or by the shaft being made square at the part as also
the hole through F). A spiral spring G bears against the collar H secured by a
stop bolt to the shaft B. the spring winding round the shaft bears equally against
the combination hanger F. At the other end of the shaft B is another combination
hanger K. (Sheet I Fig. 1. Sheet II Fig. 8).
An iron bar L connects firmly F with K. above the shaft, and a sheet iron
trough or tray M. is attached at one end to F as the other to K. and further
hangers N. N. (Sheet I Fig. 1 Sheet II Fig. 10 and 11.) are fixed both to the
iron bar and tray M.
A second frame O similar to D but without the chuck is attached to the other
end of the cylinder and revolves on and around part of the combination hanger K.
The result is that as soon as the movement of the strap E in the direction shewn
by the arrow (Sheet I. Fig. 1 and elsewhere) imparts motion to the cylinder; the
frame D, hanger F, tray M and entire cylinder recede from the chuck C. com-
pressing the spring G. which returns them all back again as soon as the form of the
jaw of the chuck allows, producing thus the to and fro motion, the intensity of
the shock and length of oscillation can be varied at pleasure by decreasing the
angles of ascent or descent of the face of the chuck. With machines of sufficient
weight to overcome the friction of the sliding on the shaft of the parts F and K,
the spring G and the collar H can be dispensed with.
The Adjustable Tray. The shaft B rests in bearings P. Q. beyond the bearing P.
(Sheet 1 Fig. 1 and 5) the shaft B. is squared to receive a handle R. (Sbeet I
Fig. 1 and 4) held in its place on the shaft by the nut S. By deviating the
handle R. the shaft B is turned and with it the hangers F and K and the tray M,
so that the edge of the tray T (Sheet II Fig. 8. 9. 10. 11) can be adjusted to any
desired position, according to the point of elevation of the indents in the cylinder
at which the grain worked on falls from the indents. To keep the edge of the
tray in its place the handle R after adjustment is fixed to the bearing P by the
bolt and butterfly nut U. The grain enters the cylinder mixed at V. (Sheet I
Fig. 1) is separated during is progress along W. W. arrives at the barrier X
(Sheet I Fig. 1 Sheet II Fig. 6 and 7) and comes out at Y. The grain that has
been separated and elevated falls into the tray M. and out at Z.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is.
1. The shape given to the indents

page_text: 2. The imparting of a to and fro motion producing a series of shocks or oscillation
both to the cylinder the tray and to all the grain that is being operated upon.
3. The adjustability of the tray edge making it possible for the same indented
cylinder to treat different sorts of grain, in combination with the means above.
claimed for imparting the desired motion to the cylinder.
