"IMPROVEMENTS IN FLOUR DRESSING MACHINES [Communicated to him from
Abroad by George. T. Smith of Jackson Michigan in the United States of
America]
In many flour dressing machines now in use there are arranged under the
machine two longitudinal channels for conveying respectively the finer and the
coarser product to the discharge end of the machinė by means of worins or ceepers.
Slides are also provided whereby the supply to the channel for the finer product
can be cut off at any desired point in the length of the machine. My invention
relates to means of altering the discharge into either of two channels arranged side
by side. For this purpose I divide the descending passage from the casing of the
drum to the discharge channels into a number of compartments each furnished with
a sliding drawer which is open at the end and has an inclined bottom. Each of
those drawers can be drawn out sideways and can be reversed in position so that
its sloping bottom can be made to direct the material falling into the drawer from
above into either of the two channels below. Thus if it should be found that the
material discharged from part of the drum is too coarse to be admitted to the
channel for finer material it is only necessary to reverse one or more of the drawers
to direct the required part of the product into the channel appropriated to the
coarser material.

WILLIAM BLECKLY DELL of N° 26 Mark Lane, in the City of London
"IMPROVEMENTS IN FLOUR DRESSING MACHINES A communication to me from
abroad by George. T. Smith of Jackson Michigan in the United States of
America
In many flour dressing machines now in use there are arranged under the
machino two longitudinal channels for conveying respectively the finer and the
coarser product to the discharge end of the machine by means of worms or creepers.
Slides are also provided whereby the supply to the channel for the finer product
can be cut off at any desired point in the length of the machine. My invention
relates to means of altering the discharge into either of two channels arranged side
by side. For this purpose, the descending passage from the casing of the drum
to the discharge channels is furnished at bottom with a number of sliding drawers
which have a sloping bottom open at one side. Each of those drawers can be
drawn out sideways and can be reversed in position, so that its sloping bottom can
be made to direct the material falling into the drawer from above into either
of the two channels below. Thus, if it should be found that the material
discharged from part of the drum is too coarse to be admitted to the channel for
finer material, it is only necessary to reverse one or more of the drawers to direct
the required part of the product into the channel appropriated to the coarser
material.
Fig 1 of the accompanying drawings shews a perspective view of the above
described construction of channels for the worms or conveyers, and Fig 2 shews a
perspective view of one of the sliding drawers detached. The shoot A leading
from the dressing machine has fixed to its underside a series of bars B B at equal
distances apart, and on the sides of these bars are formed tongues which fit into
grooves on the sides of the sliding drawers C C, which are thus held closely up
against the underside of the shoot, and are capable of being drawn out on either
side on raising the hinged parts D D of the casing. These drawers C are formed
as shewn at Fig 2, with a sloping bottom C¹ and an opening C³, so that, according
as they are placed in position with the mouth facing either the worm E or the
worin El, the material falling into them from the shoot A will be delivered into the
one or the other of the worms or conveyers. Thus it will be seen that according
as the drawers are arranged, they may either all be made to deliver the material
into the one worm or conveyer, or a certain consecutive number thereof may be
made to deliver the coarse material into the one worm, and the remainder to
deliver the fine material into the other worm, or, if at any point it be found that
by a defect in the dressing machine coarse material is being delivered into the
wrong worm, this may be at once remedied by sliding out the drawer at that point
and reversing its position, so as to cause the coarse material to be delivered into the
proper conveyer.
Having thus described the nature of the said invention and in what manner the
same is to be performed, as communicated to me by my foreign correspondent,
I claim :-
The use in dressing machines of sliding drawers or slides at the bottom of the
shoot delivering the material into the conveyers, such drawers being so arranged

page_text: with lateral openings that, according as they are placed in one position or the
other, they can be made to deliver the material into the one or the other of two
conveyers, substantially as herein described.
In Witness whereof, I the said William Bleckly Dell have hereunto set my
hand and seal this eleventh day of January, in the year of our Lord One
thousand, eight hundred, and eighty three.
