An Appliance for Feeding Bins or Receptacles for Grain and similar
Substance.
I, HENRY SIMON, Milling Engineer of No. 20 Mount Street, Manchester, in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
When wheat or other grain is poured from a spout into a bin or other receptacle,
the grains descend almost directly in one place while the impurities, such as chaff,
dirt and generally matters lighter than the grains themselves, are floated more or less
away by the air to other parts of the receptacle. Owing to this unequal distribution,
the quality of the material drawn at different times from the receptacle varies to an
inconvenient extent, at one time grain cleaner than the average issuing from it and at
another time, generally when nearly empty, grain with an undue admixture of
impurities.
This invention relates to means of obviating this inconvenience and ensuring a
comparatively uniform distribution of the grain and of the impurities throughout the
whole bin or receptacle which is effected by an appliance of the following kind.
Instead of allowing the grain with its impurities to fall directly from the supply
spout (which is usually in a central position) it is intercepted by a flat board or plate
or by an obstruction of conical, pyramidal or other convenient shape, placed a little
below the mouth of the spout. The grain and impurities falling on this obstruction,
have to spread out laterally and descend over its edge, with velocity so moderated
that there is little or no tendency of the light particles to be floated away by the
air through which they descend, and such floating away of these as does occur,
does not interfere with the uniform distribution of the impurities throughout the
grain.
Instead of allowing the material to descend over the edge throughout its whole
circumference, parts of the edge may be made with raised lips or flanges leaving
between openings by which separate streams of the material can pass over the edge.
In some cases it is of advantage to make the distributor with vanes and mount
an axis on which it is caused to revolve by the descent of the material
along its vanes, distributing the material with great uniformity throughout the
receptacle.

This invention relates to means of obviating this inconvenience and ensuring
comparatively uniform distribution of the grain and of the impurities throughout
the whole bin or receptacle which is effected by an appliance of the following kind.
Instead of allowing the grain with its impurities to fall directly from the supply
spout (which is usually in a central position) it is intercepted by a flat board or
plate or by an obstruction of conical, pyramidal or other convenient shape, placed a
little below the mouth of the spout. The grain and impurities falling on this
obstruction, have to spread out laterally and descend over its edge, with velocity so
moderated that there is little or no tendency of the light particles to be floated away
by the air through which they descend, and such floating away of these as does
occur, does not interfere with the uniform distribution of the impurities throughout
the grain.
Instead of allowing the material to descend over the edge throughout its whole
circumference, parts of the edge may be made with raised lips or flanges leaving
between openings by which separate streams of the material can pass over the edge.
In some cases it is of advantage to make the distributor with vanes and mount it
on an axis on which it is caused to revolve by the descent of the material along its
vanes, distributing the material with great uniformity throughout the receptacle.
Figs. 1, 2 and 3 of the accompanying drawings represent sections and plans of
bins A the spouts B for feeding them with grain and the interceptors C applied
according to my invention for the purpose above set forth. As shewn in Fig. 1 the
interceptor (is of pyramidal form; in Fig. 2, the interceptor C has lips projecting
upwards at its sides but is open for passage of the grain at its angles. As shewn in
Fig. 3 the interceptor C is of conical form with curved blades on its upper surface
so that the descending grain acting on these blades causes the interceptor to revolve
thus affecting more uniform distribution of the grain in the bin. As shewn in Fig. 4.
which represents a section and plan, the interceptor C has hollows formed in its
upper surface so as to distribute from four places. In Fig. 5 which also represents
a section and plan, the descending grain acts in the buckets of a wheel D causing
it to revolve and this wheel by bevil gear E gives rotation to the interceptor C
from the edge of which the grain is thrown by centrifugal force.
Having now particularly described and ascertained the nature of this, inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
In combination with a bin for storage of grain and its feed spout an interceptor
for distribution of the descending grain substantially as described."
