I, KNUD LAVSEN GELLERT of Port Adelaide in the Province of South Australia
Miller do hereby declare the nature of said invention for "AN IMPROVED COMBINED
SCALPER AND FLOUR DRESSER to be as follows:-
My invention consists of an improved machine for dressing flour in which the three
operations of scalping separating and dressing can be simultaneously carried on.
The
essential features of my invention lie in the construction of a machine with two reels
covered with silk revolving in opposite directions one inside the other, the inner reel
being considerably smaller than the outer one and projecting beyond it at both ends
and in combining with the two an internal double shaker. The reels are rotated by
means of friction rollers driven by gearing from the main shaft and are kept in position
by guide rollers placed on either side of the upper portion of the outer rims of the
reels. To prevent the silk of the inner reel from clogging I fix to the frame of the
machine a brush extending longitudinally over the centre along the top from front to
back. By supporting the reels on friction rollers I am enabled to construct them
without transverse arms. I place down the centre of the inner reel a horizontal double
shaker held by straps at the tail and covered with suitable scalping wire. The shaker
is actuated by an eccentric roller on which it rests at one end and which is driven by
belting in the ordinary way. In order to prevent the wire of the shaker from clogging
I provide a jarring lever worked by a crank shaft as used in some descriptions of bran
dusters.
In use the middlings are fed on to the tray of the shaker through the wire of which
the fine particles pass into the inner reel where they are again separated and the finer
particles pass into the outer reel to be again separated from the flour which is taken
by revolving carriers to the flour packer, the middlings being returned to the rolls
or purifiers for further treatment.
Dated this Thirty first day of January 1888.

Miller do hereby declare the nature of my invention for "AN IMPROVED COMBINED
SCALPER AND FLOUR DRESSER" 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 my invention is to reduce the number of scalpers and flour dressing
machines necessary in a mill by combining more than one operation in the same
machine accomplish this by constructing a machine having two or three but
preferably three reels or cylinders covered with bolting cloth and revolving in opposite
directions, the one inside the other. I also provide an improved method of driving
the reels by friction rollers, and for an improved construction of the reels themselves
and method of attaching the silks or cloths thereto.
In order that my invention may be the better understood I will now proceed to
describe the same by reference to the accompanying drawings in which Fig. I is a
sectional elevation of my improved reels. Fig. II an end sectional elevation of the
same. Similar letters refer to similar parts. A, is the main framework constructed
in the usual manner B, main driving wheel B, main driving shaft. C₁ C₁ rollers
or dises with V shaped edges fixed to B. D D friction rollers or discs with
▼ shaped grooves also fixed to B D₁₁ D₁, supplementary friction rollers or dises

driving wheels connected by an endless chain band. F₁.centre reel: G₁ the middle
recl. GG grooved rollers or hoops fixed to G₁. H; outer reel. H¹, H¹ grooved
rollers fixed to H. 1. Fig. Il guide rollers with V shaped edges revolving on
standards fixed to the main framework A₁. K, spindle of inner reel Fi. The inner
reel F₁ (Fig. II) extends almost the whole length of the machine. Its framework
is constructed in the usual manner and is attached to the spindle K₁ Fig. I which
revolves in suitable bearings in the framework A₁. K, is actuated by the endless
band connecting the toothed wheel E with the toothed wheel E, on the main-
driving shaft. The reel Fis covered with suitable wire gauze or bolting cloth. The
middle reel G, is slightly shorter than. the inner reel F. and of such sufficiently
large diameter as will enable it to take the stuff which has passed the cloth covering
the reel F. The framework of G, is constructed in the usual way but without
internal ribs. To each head is fixed an external hoop or ring G, having a V shaped
groove of suitable size and turned carefully true. On either side of the upper
portion of G and revolving on short spindles attached to the frame A, are placed
guide discs or rollers 1, Fig. If having V shaped edges which run in the grooved
roller or hoop G. The heads of the grooved hoop or roller G₁₁rest on, and are
driven by the supplementary discs or friction rollers D₁, which also are constructed
with: V shaped edges and which revolve on the spindles of brackets attached to the
framework A. The discs or rollers D¹, are actuated by the grooved dises or friction
rollers D, attached-to the maindriving shaft-B, the-supplementary rollers D¹, being

outer reel H, again is shorter than the reel G, and of sufficiently larger diameter. It
is constructed in a similar manner being provided with similar grooved hoops rollers
or rings H, actuated and supported at either end by V shaped rollers or disc C₁
attached to the maindriving shaft B₁, and kept in position by sets of guide discs or
rollers I, as before described. In order to facilitate inspection of the cloths of the
inner and middle reels instead of securing the cloths of the outer reels in the usual
way I attach a number of hooks to the lasting to which the edges of the cloth are
fastened and after hooking each end over a ring or hoop provided for the purpose on
each head of the reel lace the edges together. This method allows the cloths to be
expeditiously removed and replaced without damage. I do not however make any
claim for this method. By varying the sizes of the wheels E, E, and the rollers
or discs D, D, and C, the reels may be speeded differently as desired. Whilst by
varying the mesh of the covering cloths the meal may be dressed to any desired fineness
before falling into the hopper at the bottom of the machine, which being of ordinary
construction I have not thought it necessary to describe. The reels may be provided
in the ordinary way with internal or external brushes but I make no claim with respect
to these.
I find in practice that the driving power required is small and whilst aware that the
reels may be driven by gear wheels or other known methods am of opinion that the
friction rollers as before described best answer the purpose. I wish it to be distinctly
understood that I do not confine myself to any particular number of reels but prefer
to have three.
The
By driving the recls in opposite directions I secure more bolting surface.
meal falls into the inner reel from a shoot in the ordinary way but the middle
reel coming round in the opposite direction receives the bolted meal half way up its
sides and commences dressing from there to half way up the opposite side. Similarly
the outer reel coming down the opposite direction to the middle reel receives the
further bolted meal half way up its side and dresses it from there to half way up
the opposite side. By driving the meal and bolting in this way a much larger
surface of the cloth is brought in use and consequently a greater result accomplished
in the same time with the same expenditure of power.
Having now particularly described and ascertained the nature of my said
Invention and in what manner same is to be performed I declare that what
I claim is :-
First. The construction of machines for scalping or dressing flour with more reels
than one but preferably three revolving in opposite directions one inside the other
substantially as herein described.
Second. The construction of the driving gear of such reels consisting of grooved
rings or hoops actuated by discs having V shaped edges substantially as herein
described.
Third. In the construction of such reels the combination with the grooved rings
of supplementary discs for the purpose of changing the direction of the reels substantially
as herein described and for the purposes indicated.
