COMPLETE SPECIFICATION (AMENDED).
Improvements in or relating to Machines for Cleaning and
Sorting Middlings, Grist, Ground Corn, Grain, and the like.
We, FERDINAND SEEREINER, Technical Inspector of the Victoria Steam
Mills, and ANDRAS MISKY, Engineer of the Vulkan Machine Factory, Aeussere,
Weitznerstrasse 44, both of Budapesth in the Kingdom of Hungary, 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 present invention relates to a cleaning and sorting machine for middlings grist,
ground corn grain & the like the chief feature of which consists in the provision of
several cleaning floors or stories having outlets for the material under treatment
leading to the floor beneath and also others for delivering the material and in which
the openings for the air-current by means of which the cleaning is effected can be
adjusted and regulated as required.
The object of the invention is clearly set forth in the accompanying drawings in
which-
Fig. 1 is a vertical section through the machine.
Fig. 2 is a side elevation of the same.
Fig. 3 is a front elevation.
Fig. 4 is a plan.
Fig. 5 is a cross-section through the machine on the line E F of Fig. 1.
Fig. 6 is a cross-section on the line C D of Fig. 1, and
Fig. 7 is a cross-section on the line G H of Fig. 1.
Fig. 8 is a section showing a variation of the arrangement for the inlet of the
air current drawn to a larger scale.
The material to be cleaned and sorted falls through the hopper a on to the
delivery roller b its uniform distribution being effected by means of the distributing
flap d. The material is then carried by means of the roller b and the inclined
surface c to the passage e this passage being protected from the air-current by a
flap or cover of sheet metal f.
In falling from the opening e to the cleaning compartment of the top story III
the material is submitted to a current of air (shown by the arrows A) the direction
of which can be regulated by the position of the tongues v.
These tongues v also serve to regulate the sectional area of the air-current.
The heavier and larger portions of the material then fall in passing through a
further air-current (indicated by the arrow B) into the compartment g whence they
are led through a suitable passage or channel h arranged outside the machine to the
compartment I as they are now ready for being packed or otherwise dealt with.
The lighter portions of the material are carried by the air-current (indicated hy
the arrow A) over the adjustable flap into the second division of the top
story III and thence descend the inclined plane on to delivery roller b¹ of the
middle story II where they are submitted to treatment exactly similar to that

page_text: already received in the top story III by means of parts corresponding to those
contained in that story viz.: d e f g¹¹ and also air currents at A¹ and B. The
lightest portions however such as bran and the like are carried on by the air
current (which is gradually decreasing in force) to the compartment m whence
they may be led to sacks or other receptacles through the tube n.
In the lowest story I the process is precisely the same as that already described
for the other stories and here also corresponding parts b2 2 2 f2 v2 92 k² and inlets A²
and B2 for the air current are provided; in this story however the substance is
sorted into four compartments according to its size and weight.
The material carried into the division m of the middle story II and that carried
into the last division of the bottom story I may be allowed to mix.
The required current of air is produced by means of a suitable fan arranged to
draw same from the air channel or conduit W.
As may be seen on reference to Figs. 4 to 7 of the drawings the body or casing
of the apparatus is made smaller at the front or where the inlets for the air current
are arranged than at the back or where the outlets for the same are situated the
object of this is to allow of the current becoming less concentrated as it approaches
the outlets and so to permit of a complete deposit of the lighter substances and to
prevent such of it as may be of any utility from being drawn into the air
conduit W.
By making the tongues v¹² suitably adjustable it is not only possible to impart
to the air current the desired direction but also to vary its sectional area and
thereby of course its velocity as required.
In place of these adjustable tongues the arrangement shown in Fig. 8 may be
employed in which a cylinder O provided with slits or openings is used by means
of which the same effects can be obtained by rotating the said cylinder so as to direct
the air as required or cause a greater or lesser portion of the air openings to be
obstructed by the casing.
The number of stories or floors of the apparatus can of course be either increased
or diminished according to requirements.
pp are flaps or doors for regulating the outlets from the various compartments
in the machine.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. A cleaning and sorting machine for middlings grist ground corn grain and the
like having the air inlets of smaller size than the air outlets as herein before described
and shewn in the accompanying drawings whereby expansion of the said current can
take place as it approaches the outlets and its velocity and force consequently
diminishes substantially as and for the purposes herein before described.
2. The combination in a cleaning and sorting machine for middlings grist ground
corn grain and the like-having openings for the introduction of the air current-of
adjustable tongues such as v vl 2 by means of which the size of the openings can be
regulated and also the direction of the air current varied suitably to the material to
be cleaned and sorted substantially as and for the purposes hereinbefore described.
3. The combination in a cleaning and sorting machine for middlings grist ground
corn grain of a revolvable valve such as O provided with slits or openings therein for
admitting and regulation of the admission of the air current and to vary its
direction substantially as and for the purposes hereinbefore described.
