I, ARTHUR MAURICE ROBINSON, of Railway Works, Rochdale, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
In
This invention relates to wheat scouring machines in which the wheat is agitated
within a fixed perforated cylinder or drum by means of beaters or arms.
machines as at present constructed there are the disadvantages that some parts
of the cylinder or drum are more subject to wear than other parts and that some
of the perforations become clogged with dirt so that the efficiency of the perforated
surface is not uniform all round.
The object of my invention is to provide a wheat scouring machine in which
the above disadvantages shall be obviated and for this purpose I so arrange the
perforated drum or cylinder on carriers or bearings that such drum or cylinder
can be rotated by means of suitable gearing so as to allow of all parts of the cir-
cumference becoming equally worn, and to allow of portions that may be clogged
up becoming free again.
Improvements in Wheat Scouring Machines.
I, ARTHUR MAURICE ROBINSON, of Railway Works, Rochdale, in the County
of Lancaster, Engineer, 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, reference being had to the accompanying
drawings:-
This invention relates to wheat scouring machines in which as at present con-
structed, the wheat is agitated within a fixed perforated cylinder or drum by means
of beaters or arms. In these machines as at present constructed there are the
disadvantages that some parts of the cylinder or drum are more subject to wear
than other parts and that some of the perforations become clogged with dirt so
that the efficiency of the perforated surface is not uniform all round.
The object of my invention is to provide a wheat scouring machine in which
the above disadvantages shall be obviated and for this purpose I so arrange the
perforated drum or cylinder on carriers or bearings that such drum or cylinder

cumference of such drum or cylinder becoming equally worn, and to allow of

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a longitudinal section, and Fig. 2 a transverse section of a wheat
scouring machine illustrative of my invention. a is a perforated drum or cylinder
of any usual kind b b¹ carriers to which the drum a is attached by bolts and nuts c
or otherwise as desired. The carriers 6 6 revolve, on bearings d formed with or
secured to the casing e of the machine. One of the carriers b is provided with
a toothed wheel f into which gears a worm 9 on a shaft h so that by turning the
shaft h rotary motion is communicated to the drum or cylinder a, so that all
parts of the circumference of such drum come in turn into position of hardest
wear which is near the lower part of the machine thereby ensuring greater and
more uniform efficiency of the perforated surface, and allowing of any dust or
dirt that may lodge in the perforations falling out again. Brushes or other well
known cleansing devices may be used if desired to assist the clearing of the perfora-
tions. The shaft h is caused to revolve by any convenient gear such as bevel
wheels and pulleys as shewn, i are the usual beaters for agitating the grain, j feed
hopper outlet for grain, discharge hopper for dust &c.
I do not confine myself to the particular arrangements of parts described as
many modifications may be made without departing from my invention, as for
instance the rotary perforated drum a may be carried on rollers or otherwise and
may be caused to rotate by any convenient gearing as well as by wheel and worm
gear.
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:
Wheat scouring machines having a perforated drum or cylinder capable of
being rotated substantially as and for the purposes set forth.
