Improvements in Apparatus for Dressing Grain or Separating
Foreign Matter therefrom.
We, THOMAS 'NALDER, of Wantage, and WILLIAM NALDER, of Challow, and
ERNEST THOMAS WILSON NALDER, of Wantage, all in the County of Berks,
Engineers, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide apparatus whereby foreign matter
such as bag-ties or other substances can be separated from grain with speed,
economy and facility. According to this invention the grain from which foreign
substances are to be separated, is subjected to the action of a series of prongs, spikes,
or the like which are caused to move upward through a descending
body of grain, the said prongs, spikes, or the like, allowing the
grain to pass between them
but intercepting and carrying upward
and discharging to the other side, any bag-ties, or other foreign matter
contained in the grain. The said prongs, spikes, or the like may be carried by
a roller, or a band passing over rollers, the said roller, or rollers, being mounted
in a casing with an inlet for the grain onto the prongs, spikes, or the like, and with
outlets respectively for the grain which passes between the prongs, spikes, or the
like, and for the foreign substances separated and carried over by the prongs,
spikes or the like. The said prongs, spikes, or the like, may act in conjunction
with prongs, spikes or the like arranged so that those on the band pass between
them and these additional prongs, spikes, or the like, may be fixed to the inside
of the casing or be upon a band, or roller, which may be rotated, so that both
series of prongs, spikes, or the like move upwards to act upon the grain and
separate foreign substances therefrom. The apparatus may be used as a separate
machine, or in combination with machines for elevating, or further dressing or
otherwise treating grain.

Improvements in Apparatus for Dressing Grain or Separating
Foreign Matter therefrom.
We, THOMAS NALDER, of Wantage, and WILLIAM NALDER, of Challow, and
ERNEST THOMAS WILSON NALDER, of Wantage, all in the County of Berks,

page_text: Engineers, 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:-
The object of this invention is to provide apparatus whereby foreign matter
such as bag-ties or other substances can be separated from grain with speed,
economy and facility. According to this invention the grain from which foreign
substances are to be separated, is subjected to the action of a series of prongs, spikes,
or the like which are caused to move upward through a descending
body of grain, the said prongs, spikes, or the like, allowing the
grain to pass between them but intercepting and carrying upward
and discharging to the other side, any bag-ties, or other foreign matter
contained in the grain. The said prongs, spikes, or the like may be carried by
a roller, or a band passing over rollers, the said roller, or rollers being mounted
in a casing with an inlet for the grain onto the prongs, spikes or the like, and with
outlets, respectively, for the grain which passes between the prongs, spikes, or the
like, and for the foreign substances separated and carried over by the prongs,
spikes or the like. The said prongs, spikes, or the like, may act in conjunction
with prongs, spikes, or the like arranged so that those on the band pass between
them, and these additional prongs, spikes, or the like may be fixed to the inside
of the casing or be upon a band, or roller, which may be rotated, so that both
series of prongs, spikes, or the like move upwards to act upon the grain and
separate foreign substances therefrom. The apparatus may be used as a separate
machine, or in combination with machines for elevating, or further dressing, or
otherwise treating grain.
The accompanying drawings represent an arrangement of apparatus according
to this invention. Figure 1 is a vertical section (on the line 1, 2 Figure 2).
Figure 2 is a vertical section (on the line 3, 4 Figure 1). Figure 3 is a horizontal
section (on the line 5, 6 Figure 1) and Figure 4 is a side elevation.
A is a box or casing having a feed inlet opening a and spreading valve a*.
Inside the case are the prongs B forming a fixed rake. The part A3 at the bottom
of the casing A separates the outlet A³ for grain, from the outlet A for bag-ties
or other foreign substances removed from the grain. C is a band carrying prongs c
the said band passing over the small pulleys &³ d' and over a pulley d driven in
the direction of the arrow by any suitable power applied to the pulley d. The
pulleys are shewn as being mounted in adjustable bearings for regulating the
tension of the band.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. For dressing grain or separating foreign substances therefrom an apparatus
wherein a series of prongs, spikes or the like are moved upwards through a
descending body of grain, substantially as herein before described.
2. An apparatus for dressing grain or separating foreign substances therefrom
consisting of a passage for a descending body of grain and an endless band or
bands or the like carrying series of prongs, spikes or the like and means for
passing them upwards through the said passage and discharging through a
separate outlet or separate outlets bag-ties or other foreign substances separated
from the grain, substantially as hereinbefore described.
3. An apparatus for dressing grain or separating foreign substances therefrom
the said apparatus consisting of a passage for a descending body of grain and
provided with stationary prongs, spikes or the like and an endless band or the
like carrying prongs, spikes or the like and means for passing them upwards
between the stationary prongs, spikes or the like and discharging at the opposite
side bag-ties or other foreign substances separated from the grain, substantially as
herein before described.

page_text: 4. An apparatus constructed and arranged as hereinbefore described and illus-
trated in the accompanying drawings.
