HENRY SIMON, of No. 7, St. Peter's Square, Manchester, in the County of
Lancaster. IMPROVEMENTS IN APPARATUS FOR DISAGGREGATING CAKED OR
FLAKED FLOUR AND OTHER SIMILAR SUBSTANCES." [A communication from abroad
by Gustav Daverio, of Oberstrass, near Zürich, and Johann Heinrich Bünzli, of
Uster, both in Switzerland.]
This Invention relates to apparatus such as was described in the Specification to
Wirth's Patent, No. 4305, of 1877, for disaggregating or detaching from each other
the particles of flour or other pulverulent substances adhering to each other in the
form of flakes or small lumps, such apparatus consisting mainly of a disc with
grooved face fixed within a casing, in close contiguity to the grooved face of which
disc is a revolving disc, so that the flakes being fed in through a central holo in the
fixed disc are subject to a rubbing action between the fixed and revolving grooved
faces, whereby the particles of the flakes are detached from each other, and escape
at the periphery of the discs into the casing.
According to the present improvements there is fixed on the central part of the
rotating disc a flyer, having arins recurved so as to project outwards, the material
entering through the central feed opening, and thus to bring the material more
rapidly under the action of the rubbing surfaces of the discs. The spindle of the
rotating disc, which, subject to spring pressure, has certain freedom of movement in
the direction of its length, has its spring and stop adjusted as follows:-On the one
end of this spindle is fixed a collar, against which abuts one end of a helical spring,
the other end abutting against a sleeve which is loose on the spindle. This sleeve
is fitted with a feather to slide within a hollow boss projecting from one of the
bearing frames of the spindle, being prevented by the feather from turning. On.

page_text: the outside of the hollow boss is a screw thread, on which works a nut and band
wheel, the face of the nut bearing against a collar on the sliding sleeve. By turning
the nut in the one direction the sleeve is moved outwards, compressing the spring
which abuts against it, and so increasing its elastic force, and by turning the nut in
the opposite direction the spring is allowed to expand, having its elastic force
reduced. At the other end of the spindle there is a similar arrangement of parts
without the spring, the sliding sleeve in this case bearing directly against the collar
fixed on the end of the spindle, and forming an adjustable stop, which pre-
vents the spring from drawing the spindle in the direction of its length, and so
regulates the distance between the faces of the triturating discs.
According to another arrangement the one end of the spindle has a central recess,
in which is placed a helical spring, and against the outer end of this is a disc fitting
with a feather in the recess, so that it is prevented from rotating in the recess.
Against this disc presses the end of a screw spindle screwing through the bearing
frame, and provided outside with a hand wheel, so that by turning the screw by
means of the latter the spring can be more or less compressed, thereby pressing the
spindle with a greater or less elastic force in the direction of its length, and tending
to bring the revolving disc nearer to the fixed disc. At the other end of the spindle
is also a central recess of tapering form, into which is fitted a tapering steel head,
on which bears the end of a screw spindle screwing through the bearing frame, so
that by turning such screw spindle by means of a hand wheel the spindle with the
revolving disc can be adjusted nearer to or farther from the fixed disc.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Henry Simon in the Great Seal Patent Office on the 23rd
December 1879.
HENRY SIMON, of No. 7, St. Peter's Square, Manchester, in the County of Lancaster.
"IMPROVEMENTS IN APPARATUS FOR DISAGGREGATING CAKED OR FLAKED FLOUR AND
OTHER SIMILAR SUBSTANCES." A communication from abroad by Gustav Daverio,
of Oberstrass, near Zürich, and Johann Heinrich Bünzli, of Uster, both in
Switzerland.
This Invention relates to apparatus such as was described in the Specification to
Wirth's Patent, No. 4305 of 1877, for disaggregating or detaching from each other
the particles of flour or other pulverulent substances adhering to each other in the
form of flakes or small lumps, such apparatus consisting mainly of a disc with
grooved face fixed within a casing, in close contiguity to the grooved face of which
disc is a revolving disc, so that the flakes being fed in through a central hole in the
fixed disc are subject to a rubbing action between the fixed and revolving grooved
faces, whereby the particles of the flakes are detached from each other, and escapo
at the periphery of the discs into the casing.
According to the present improvements there is fixed on the central part of the
rotating disc a flyer, having arms recurved so as to project outwards, the material

page_text: modified arrangement of adjusting gear, shown to an enlarged scale by Figs. 3 and 4,
referring first to Fig. 3, the spring is inserted in a hole bored into one end of the
shaft, in which hole there is fitted with a feather a steel disc m, so that it can
slide in the hole, but must turn with the shaft. The end of the shaft works in a
bush of a bearing n, through the end cover of which works a screw o, having a
steel end that bears against the discm. At the other end of the shaft, as shewn by
Fig. 4, a steel centre q' is driven into a taper hole bored in the shaft, and against
this centre bears the steel end of a screw o¹ that works through the end cover of
the bearing n. By turning the screws o and o¹ by the hand wheels p, p, the
position of the shaft, and consequently the distance between the discs, can be
adjusted, the spring giving yielding elastic pressure in the one direction. The
screws o, o, are prevented from turning by setting nuts 8, 8', and the rubbing
surfaces are lubricated by oil passing through holes drilled in the screws.
Having thus described the nature of the said Invention and in what manner the
same is to be performed, as communicated to me by my foreign correspondents, I
claim in respect of apparatus for disaggregating caked or flaked flour and other
similar substances,-
First. Providing on the rotating disc a central flyer having recurved arms, sub-
stantially as and for the purposes herein set forth.
FL
Second. The construction and arrangement of adjusting gear, consisting of the
combined parts c, d, e, f, and g, at the one end of the shaft, and c¹, d', e¹, f¹ g¹, h¹,
and at the other end of the shaft, as herein described with reference to Fig. 1 of
the accompanying Drawings.
Third. The modified construction and arrangement of adjusting gear, consisting
of the combined parts l, m, n, o, and p, at the one end of the shaft, and n³, o¹, p²,
and q at the other end of the shaft, as herein described with reference to Figs. 3
and 4 of the accompanying Drawings.
In witness whereof, I, the said Henry Simon, have hereunto set my hand
and seal, this Twentieth day of November, in the year of our Lord One
thousand eight hundred and seventy nine.
