Improvements relating to Apportioning in Predetermined Quantities
Grain, Seeds, Spices, and Granular Materials generally.
1, WILLIAM RICHARD CLARKE, trading W. G. Clarke and Son, of the
Anchor Biscuit Works, Limehouse, London, E. Biscuit Manufacturer, Seed Flour
and Grain 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 :-
My improvements are devised with a view to effect by the hereunder described
means and method which I employ according to my invention, the expeditious and
accurate apportioning-previously to being mixed or otherwise treated--of pre-
determined quantities say of grain of different grades, qualities or designations.
Thus for instance as would occur when it is wished to produce a total quantity of
so many proportions of grain in which shall be present predetermined quantities
having differing values or properties.
In order that the means which I employ for carrying out my invention may the
better be understood, I have appended the accompanying sheet of drawings to
which I will proceed to make reference.
Figure represents a longitudinal sectional view of my improved device with
two of the reversible cells (hereinafter more particularly referred to) open, and
Figure 2 a plan view of same.
In carrying out my invention and taking, by way of illustration, the case when
dealing with grain, I employ arranged underneath the store hopper shoot of the
bin, a rectangularly shaped frame a, hereinafter termed the cell frame, with fillet
pieces or ledges extending along at the bottom and inside thereof. Between the
two sides of the framing a and resting upon the fillets or ledges bare fitted any
desired number of trough shaped reversible cells c each of which I will assume to
be capable of holding a bushel. These cells are preferably made up of three
portions, so that when closed they consist of a top and bottom portion and a back,
which latter forms a partition against the next cell whether open or closed.
When any of the cells are required to be opened for use, they are lifted out of the
cell frame a and replaced in a reversed position the top and bottom portions then
form two side pieces and take a bearing against the sides of said cell frame a
whilst the back also in this case forms the partition, thus leaving the top and
bottom open for the reception and discharge of the grain.
The cell frame a aforesaid is closed at each end and is disposed, and free to have
a reciprocating motion, within the compound cap picce d. The base e of which is
secured to a frame supporting a worm conveyor for the purpose of mixing the
various proportions discharged from the machine. The base is also provided with
discharge apertures ff. The top of the cap piece d is bridged over, as shown
Figure 1, and is provided with an aperture, which corresponds in size with two of
the cells c. The vertical extension g of the cap piece d forms a supplementary
bopper, into which depends the shoot of the main hopper from the bin. It is
provided at its upper portion with a valve for shutting off the charge of material
from the bin when a certain grade is not required to be apportioned.
Reciprocatory motion is imparted to the cell frame a by means of any suitable
arrangement of levers, eccentrics or gearing. Each of the cell frames a being
provided at one end as shown with an extension rod i. The outer end of which

page_text: would be preferably connected to a bar to which reciprocating motion is given
and by it imparted to the rods of the series of cell frames e.
The working of the apparatus is as follows; that is to say:-I employ any
suitable number of the above described apparatus, arranged parallel to each other
underneath a series of bins containing the different grades of material and each
being caused to reciprocate to and fro as aforesaid.

"
Now supposing it is required to deliver a certain quantity of material say grain
preparatory to its being mixed, for instance 100 sacks, consisting of equal pro-
portions of the first four qualities; any suitable number of the cells care opened, in
the manner herein before Stated, as also the valves commanding each series of cells.
Reciprocating motion is then imparted to the cell frame a; and, those of the
cells which are open, on the forward stroke of the frame, receive a charge, become
filled with material and at the same time to exact "struck measure; then, on the
continuation of the travel of the frame a the material is discharged on the cells c
reaching the aperture f' is the base e; and, on the backward stroke of the frame a,
the same operation takes place and the material is discharged through the
apertures; from which apertures f,f the material would descend into a trough
in which works a screw conveyer to admix the material or materials previously
apportioned as aforesaid and to discharge same at the point or points desired.
When the required amount of material has been supplied from the bins, the
valves are closed, whereupon the supply to the cells will cease.
I do not confine myself to the exact number of cells c. In Figure 1 of the
accompanying drawings I have shown eight, which, if each represent one bushel,
would discharge one quarter exact "struck " measure, at each stroke, as these
may be varied in size, shape and number, and of any suitable material to suit
different requirements.
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 apparatus substantially as herein described and shown to allow of the exact
apportioning of granular materials generally in predetermined quantities and to
exact struck measure.
