"IMPROVEMENTS IN
to be as
follows:-
OR RELATING TO FLOUR DRESSING MACHINES
"
The object of this invention is to provide simple and effective means or apparatus.
for cleaning the meshes of the reels of flour dressing machines.
In machines as at present constructed great difficulty is experienced by the
meshes of the silk. or wire covering of the reel becoming choked or filled with dust,"
and thereby rendering the machine inoperative. When this occurs the reel has to
be cleaned by hand. Many attempts have been made to prevent the dust
accumulating or collecting in the meshes, but with only partial success.
The means or apparatus we employ is simple, effective, and capable of being
applied either to cylindrical or polygonal reels.
The sweeping or cleaning apparatus consists of a shaft carried in suitable
bearings, and passed within the framework of the machine parallel to the axis of
the reel. This shaft may be fixed or carried either above or below the reel, but
we prefer to place it in any convenient position above the centre of, and at a
suitable distance from the reel. On the shaft is mounted and fixed two or more
castings provided with any desired number (preferably two) of arms or projections.
On each arm or projection is mounted and carried an adjustable clamping device
consisting of two rails fastened together. These rails may either extend across the
whole face of the reel, or only for a portion of the distance. Between each set of
clamping rails is inserted a strip or piece of cloth, felt, india rubber, or other
elastic or flexible material of any suitable width, and in such a manner that when
the shaft and castings are caused to revolve in an opposite direction to that in
which the reel is rotating, the strips or pieces of cloth, felt, or india rubber are
caused to strike against and sweep the periphery of the reel thereby removing all
dust from the meshes of the silk or wire covering.
Motion is preferably conveyed to a pulley on the "sweeper" shaft from the
beater shaft or from any other convenient moving part of the machine by ordinary
means.

We, WILLIAM WHITE of 68, Lofthouse Place Leeds, in the County of York,
Millwright, and JOHN FOSTER MILNER, of Woodside Corn Mills, Elland, in the
County of York, Corn Miller, 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 object of this invention is to provide simple and effective means or apparatus
for cleaning the meshes of the reel covering of flour dressing machines.
In machines as at present constructed great difficulty is experienced by the
meshes of the silk or wire covering of the reel becoming choked or filled with dust,
and thereby rendering the machine inoperative. When this occurs the reel has to
be cleaned by hand. Many attempts have been made to prevent the dust
accumulating or collecting in the meshes, but only with partial success.
The means or. apparatus we employ is simple effective, and. capable of being
applied either to a cylindrical or polygonal reel, and will be best understood by aid
of the accompanying drawings in which Fig. 1. is a longitudinal elevation, and
Fig. 2. a transverse section of the revolving sweeping apparatus, taken at right
angles to fig. 1.
A is the reel with silk or wire covering, and B the framework of the machine,
C the revolving sweeping apparatus consisting of a shaft c two or more castings D
provided with arms d carrying adjustable clamps E for receiving the sweeping.
strips or pieces F. The shaft c is mounted and carried in suitable bearings c¹
which may be attached in any convenient manner to the framework, and the shaft
is passed within the framework B parallel to the axis a' of the reel A. We prefer
to place this shaft above the centre of and at a suitable distance from the periphery
of the revolving reel A as shown at C in the drawings. On the shaft c are
mounted two or more castings D provided with any desired number of arms or
projections d. In the drawings we have shown four of these castings each having
two arms d, but these can be increased as required. On each arm dis mounted.
and carried, an adjustable clamp E formed by fastening two rails e together (by
preference) by the same bolts e as secures the rails e to the arms d. Slot holes d¹
are made in each arm & through which the bolts e¹ pass which permit of the rails e
and sweeping strips or pieces F being adjusted in any desired position on the arm d.
Each set of rails e may either extend across the whole face of the reel A or be
made in two or more portions or sections as shown in the drawings. Between
each set of clamping rails e is inserted a strip or piece F of cloth, felt, india rubber,
or other elastic or flexible material of the same length as the rails e and of such a 'width
that during its rotation it is made to sweep or clean one of the flattened surfaces
or angles a of the reel A. The revolutions of the sweeper C and reel A are so
timed that as one strip F.is passing off a flattened surface or angle a a second
strip F is just commencing to sweep or clean the next succeeding flat or angle a.
It will be readily understood. that for polygonal reels the width of the pieces or
strips will vary in accordance with the breadth or size of the angles or flattened
surfaces on the reel. But for cylindrical reels the strips or pieces F are of such a

page_text: width, and so arranged that as one strip or piece passes off the periphery of the
reel another strip commences to sweep at the point or place where the former one
left off. The sweeping apparatus C revolves at a greater speed in the same or an
opposite direction to that in which the reel A rotates and causes the strips or
pieces to strike against and sweep the periphery of the reel, thereby removing all
dust from the meshes of the silk or wire covering. A continuous rotary motion is
preferably conveyed to a pulley G on the sweeper shaft c from the beater shaft a¹
or from any other convenient moving part of the machine by ordinary means. By
the above described means or apparatus every portion of the reel whether polygonal
or cylindrical is regularly and constantly swept and cleaned, and any dust adhereing
to or accumulating in the covering of the reel is swept off or removed.
Although we have shown and described our invention applied to the reel of a
centrifugal machine we wish it to be distinctly understood that it is applicable to
the reels (having a covering of silk or wire) of all machines used in the various
processes or operations of dressing flour and known in the trade as ordinary reel,
break meal, redressing, and scalping machines.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
"
First. The manufacture and use of a rotating sweeping apparatus for cleaning
and sweeping the silk or wire coverings of cylindrical or polygonal reels of flour
dressing machines whilst they are in motion, consisting of a shaft running through
and within the framework of the machine parallel to the axis of the reel, and
carrying two or more armed castings provided with adjustable clamps in which are
inserted strips or pieces of cloth, felt, india rubber, or other elastic or flexible
material which sweep and remove the dust from the meshes of the reel covering
substantially as herein described.
Second. In flour dressing machines and in combination with cylindrical or
polygonal reels, a sweeping apparatus substantially as herein described and
illustrated, extending in one or more portions or sections across the face of the reel
and driven from some moving part of the machine so as to revolve at a greater
speed than that at which the reel is rotating, for sweeping and removing any dust
adhering to or accumulating in the meshes of the reel covering.
Third. The arrangement and combination of the various parts forming the
revolving sweeping and cleaning apparatus as a whole substantially as herein
described and illustrated.
