page_text: I, ALPHONS STEIGER, of 122 Rumford St Chorlton-on-Medlock, Manchester in
the County of Lancaster Milling Engineer, do hereby declare the nature of this
invention, to be as follows:-
My invention relates to improvements in break-scalping and flour dressing
machines and has for its objects, firstly to separate & divide in one machine those
particles of the wheat grains, from the flour, after passing through the roller mill
or stones, which might cause injury to the silk covering, whose function is only to
dress the flour or fine middlings.
Secondly, to permit the material to pass through such machine in a more natural
way & straight course, thus preventing injurious friction, caused by worms, etc, the
coarse material, instead of being brought back to the feed end, is passed on directly
to a lifting and double spiral cross feeding device, by which it is discharged into a
spout situated immediately below.
"
Thirdly, to utilize the surface of the whole length of the machine for flour
dressing, the first compartment producing the soft flour, while the better quality
of flour is obtained from the second or following compartments.
Fourthly, to prevent vibration of the shaft in the middle of the machine, thus
ensuring the durability or better working of the machine.
In order to obtain these objects I divide the whole length of the machine
into two or more compartments, which are separated by a respective number of
rotary discs or plates acting as a lifting and spiral cross-feeding device, described
hereinafter.
Inside of these compartments I arrange a shaft rotating at a considerable speed
on which I fix by means of arms forming a star, a suitable number of beaters; the
distance of the beaters from the axle being different in each compartment.
The first compartment is provided with a cover of perforated sheet iron or
wire gauze forming a hexangular or octangular prism in which the beaters can
revolve.
This first compartment is fed by means of a spout which permits the material
to be treated to enter freely into the said compartment and be submitted to the
action of the beaters.

page_text: The fine material such as flour dunst and fine middlings will be caused to pass
through the meshes of the metal cover by the action of the said beaters and fall
into a space, limited inside by the said metal cover and outside by a silk cover or
reel forming an octangular prism, like the inner one.
These prisms are formed by means of discs employed at each end and connected
together by rods of T or other shape, and are rotated at a slow, or the usual speed
of ordinary flour bolting reels, permitting the soft flour adhering to the dunst and
fine middlings to pass through the meshes of the silk cover on the same principle
as in ordinary flour or bolting reels.
In order to bring the material retained in the inner or metal prism, and the
meal which has not passed through the outer or silk cover prism, to the discs
forming the lifting & spiral cross feeding device, the beaters inside the metal prism
are of a helical form, and carry the material forwards from the entrance or the
feed end towards the said lifting & spiral cross feeding device, while the meal
retained by the silk cover is carried towards the lifting and spiral cross feeding
device by means of inclined blades fixed between the rods forming the frame for
the silk cover. The lifting and spiral cross feeding device, forms a partition
between the different compartments, and consists of a small concentric cone-shaped
disc, the cone portion fitting against a larger disc, between which discs a suitable
number of shovels or buckets, in shape similar to those of a turbine, are arranged,
which during their revolution, slowly lift the broken wheat grains, or any coarse
material, which did not pass through the meshes of the metal cover, and discharges
them towards the centre of the cone portion of the said small disc, and then into
openings formed in the larger disc, thus permitting this material to enter into a
Becond number of shovels or buckets of the spiral cross feeding device, which
are fitted between another cone-shaped disc and against the second or middle one,
which brings the material to the circumference of the outer cover, from whence it is
delivered to a special spout passing through the hopper of the machine.
The buckets of the two compartments of the lifting and spiral cross feeding
device form a continuous curve, being tangent to a concentric circle or cone so as
to form no impediment for the free passing of the material through the buckets.
The meal between the wire and silk covers being brought towards the lifting
& spiral cross feeding device already described falls into other buckets, following
the same curve, as already described for causing the coarse material to leave the
revolving frame, in such a manner that it cannot mix again with the coarse
materials, but is forced to enter the second compartment of the machine where it
is submitted to the treatment of the other beaters which through their action,
cause the flour or other fine material to pass through the said silk cover.
The material, which is too coarse to pass through the said cover is brought
forward to the end of the machine (or the next spiral cross-feeding device) in
exactly the same way as in the first compartment, where the beaters are fixed
helically and leave the machine through a special spout.

Machines.
I, ALPHONS STEIGER, of 122 Rumford St. Chorlton-on-Medlock, Manchester in
the County of Lancaster, Milling 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:—
My invention relates to improvements in break scalping and flour dressing
machines and has for its objects, firstly to separate and divide in one machine
those particles of the wheat grains, from the flour, after passing through the
roller mill or stones, which might cause injury. to the silk covering whose function
is only to dress the flour or fine middlings.
Secondly, to permit the material to pass through such machine in a more
natural way & straight course, thus preventing injurious friction, caused by
worms, etc, the coarse material, instead of being brought back to the feed end is
passed on directly to a lifting and double spiral feeding device, by which it is
discharged in a spout situated immediately below.
Thirdly, to utilize the surface of the whole length of the machine for flour
dressing, the first compartment producing the soft flour, while the better quality of
flour is obtained from the second or following compartments.
Fourthly, to prevent vibration of the shaft in the middle of the machine, thus
ensuring the durability or better working of the machine.
And in order that this invention may be better understood I have caused to
be appended hereunto two sheets of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1. Sheet I is a vertical longitudinal section. Figs. 2. 3. 4 & 5 Sheet II
vertical cross sections at A-B, C-D, E-F, and G-H, respectively.
In carrying out my objects, and referring to the figures generally I divide the
whole length of the machine into two or more compartments a & b, which are
separated by a respective number or sets of rotary discs or plates, c. c¹, acting as
a lifting and spiral cross feeding device, described hereinafter.
Inside of these compartments a & 6 I arrange a shaft d rotating at a considerable
speed, on which I fix by means of arms e forming a star, a suitable number of
beaters f and f¹, the distance of these beaters from their axle being different in
each compartment.
In the first compartment a is employed a cover or reel g of perforated sheet iron
or wire gauze forming a hexangular or octangular prism in which the beaters f
can revolve.
This first compartment is fed by means of a spout h which permits the material
to be treated to enter freely into the said compartment a and be submitted to the
action of the beaters f.
The fine material such as flour, dunst, and fine middlings will be caused to
pass through the meshes of the metal cover or reel g by the action of the said

page_text: beaters and fall into a space, limited inside by the said metal cover or reel g.
and outside by a silk cover or reel h³ forming an octangular prism, like the inner
one g.
These prisms are formed by means of discs c³, os having long bosses s¹ and 8*
employed at each end and connected together by rods í of T or other shape and
are rotated at a slow or the usual speed of ordinary flour bolting reels, permitting
the soft flour, adhering to the dunst and fine middlings, to pass through the meshes
of the silk cover or reel, on the same principle as in ordinary flour or bolting reels.
In order to bring the material retained in the inner or metal prism g & h'
respectively, and the meal which has not passed through the outer or silk cover
of prism h¹ to the discs c and d forming the lifting and spiral feeding device, the
beaters finside the metal prism gare of a helical form, and carry the material
forwards from the entrance in the feed end towards the said lifting and spiral cross
feeding device, while the meal retained by the silk cover or reel h¹ is carried
towards the lifting and spiral cross feeding device by means of inclined blades k
see Figs. 2 & 3 Sheet II. fixed between the rods i forming the frame for the silk
cover or reel h¹. The lifting and spiral cross feeding device, forms a partition
between the different compartments a & b and consists of a small concentric cone
shaped disc projecting into the metal prism or reel g, and the cone portion fitting
against a larger disc c between which discs and o a suitable number of shovels or
buckets in shape similar to those of a turbine, are arranged, which during their
revolution, slowly lift the broken wheat grains, or any coarse material, which did
not pass through the meshes of the metal cover or reel g and discharges them
towards the centre of the cone portion of the said small disc and then into
openings formed in the larger disc c thus permitting this material to enter
between a second number of shovels or buckets of the spiral cross feeding device
which are fitted between another disc c¹ having a cone, and against the second
or middle one c which brings the material to the circumference of the outer cover
or reel h¹ from whence it is delivered to a special spout m passing through the
hopper o, out of the machine. The buckets 1 and 2 of the two compartments of
the lifting and spiral cross feeding device form a continuous curve being tangent
to a concentric circle, or the cones & , so as to form no impediment for the
free passing of the material between the buckets and 1.
The meal between the wire and silk covers 9 & h¹ being brought towards the
lifting & spiral cross feeding device already described, falls into other buckets 15,
following the same curve as already described for causing the coarse material to
leave the revolving frame or reel h¹ in such a manner that it cannot mix again
with the coarse materials, but is forced to enter the second compartment b of the
machine through openings le formed in the disc o² see Fig. 5, over which openings 1®
cone segments are arranged to prevent such material from being mixed again
with the coarse material which passes through the buckets and opening &, where
it is submitted to the treatment of other beaters f¹, which through their action,
cause the flour or other fine material to pass through the said silk cover or reel h¹.
The material, which is too coarse to pass through the said cover or reel h¹ is
brought forward to the end of the machine (or the next spiral cross feeding device)
in exactly the same way as in the first compartment where the beaters f are fixed
helically and leave the machine through a special spout.
The shaft & and beaters f and f¹ are rotated quickly from the feeding end, and
the reels h¹ and g formed by means of the rods i and discs c & c¹ and discs c³ & c³,
(viz, spiral cross feeding device), from the tail end of the machine in the following
manner.
The shaft d is driven by means of the pulley p which is fixed on the respective
or feed end of the machine and the collecting worm q. situated in the hopper o
underneath the reel h¹ by means of the pulleys 8 and t and strap t¹ all fixed on
the driving and collecting worm shafts d and q respectively, on the tail end of the
machine,

page_text: Next to the pulleys is fixed on the boss 8¹ of the end disc c³, a chain wheel u which
receives the rotary motion from another chain wheel u¹ fixed on the collecting
worm shaft q by means of a chain u². The bosses 8 and 8 of the discs c³ & c³ are
internally fitted with bushes q' and q in which the driving shaft d is rotating
quickly. The discs c³ and c³, viz, their bosses, are carried at each end of the
machine by the bearings r & r¹.
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
1st The general arrangement & combination of parts constituting my improve-
ments for the purposes and substantially as herein before described & shown.
2nd The combination of a scalping machine and flour dressing machine on one
shaft in such a manner that the scalping is performed only on a part of the
whole length of the machine, while the flour dressing is performed on the whole
length of the machine, partly in the ordinary way of the bolting & partly as
centrifugal flour dressing machine substantially as set forth.
3rd In centrifugal break scalping and flour dressing machines with two reels g
and h¹ arranged one inside the other, the employment of a lifting and spiral cross
feeding device rotating slowly with the reels g and h¹ and consisting of two cone
shaped discs and c¹, the narrow parts of the cones of the discs fitting against a
disc C, which is provided with openings the cone shaped disc projecting into the
scalping reel g. and being connected with the disc c by means of the shovels or
buckets, and disc c provided with openings and segmental cones 1, and
disc c¹, by means of the shovels or buckes and 1 in order that a continuous
spiral course through the buckets 1, 13, and is obtained the buckets and 15
serving to bring the material which remains in the scalping reel out of the machine,
while the undressed material which has fallen between the reels g and h¹, is brought
separately from the other, through the buckets and opening into the second
part of the dressing reel, as set forth.
