According to the present Invention, apparatus for disintegrating or for mixing
substances, or for simultaneously disintegrating and mixing them, is constructed as
follows: A partially cylindrical casing or drum with flat end surfaces has
projecting into it from one side a central shaft driven at a rapid speed by a pulley
and belt or other suitable gearing outside the casing, and carrying one or more
strong blades fitting against the sides and circumference of the casing.
In the side of the casing opposite that through which the shaft passes is formed
a central aperture, through which the substances to be disintegrated or mixed are
introduced. The cylindrical surface of the casing extends round three-fourths of the
circumference, from which points the surface is extended tangentially from each
side, thus forming a square corner to the cylindrical casing. The one such
tangential surface has formed in it the exit orifice for the discharge of the materials
after being disintegrated or mixed, such orifice being either closed by a slide or with
a removeable steel plate having a number of small holes or slits corresponding with
If the latter is
the degree of fineness to which the substances are to be reduced.
employed the substances on being introduced through the central charging hole
are first thrown with violence against the cylindrical part of the casing by the

then on being carried round they are thrown by the blades in a tangential direction
against the perforated plate or grating, whereby they are still further disintegrated,
those particles that are reduced to the required degree of fineness escaping through
the perforations or slits, while the other particles in falling back between the blades!
are again carried round and acted upon, as above described. If the exit orifice is
closed by a slide, this is kept closed until the whole of the charge has been reduced
to the required degree of fineness, or until it is sufficiently mixed, this being
ascertained by opening a small orifice in the circumference of the casing, and
allowing a sample to pass out the slide is then opened and the contents
discharged.
The blades are by preference four in number, and faced with removeable steel
plates.

DESCRIPTION OF THE DRAWINGS.
Fig. represents a longitudinal section, and Fig. 2 a transverse section of
apparatus according to this Invention of disintegrating and mixing substances.
A is a strong casing, having a central opening at B on its one side for introducing
the materials to be operated on, and having an outlet opening at C, towards which
part of the periphery is continued in a tangential direction. Within the casing
revolves the wheel D having one, two, or more arms, of which four are shewn in
the Drawing, each arm being faced with a steel plate E.
The outlet opening C when the apparatus is used for disintegration is fitted with
a steel grating F, as shewn in the part sectional plan at Fig. 3, with narrow
interstices between the bars, through which the more comminuted portions of the
material are ejected.
For mixing purposes the opening C may be closed by a steel plate G, as shewn in
the part vertical section at Fig. 4, the said plate having through it a discharge
hole closed by a slide H.
A hole fitted with a plug is made in the periphery of the casing at K, by which
samples can be withdrawn while the machine is at work.
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 correspondent, I
claim, the construction of disintegrating and mixing apparatus, wherein a blade or
blades revolving within a casing cause materials introduced therein to impinge
against a screen or wall facing a tangential passage from the casing, substantially as
herein described.
In witness whereof, 1, the said Henry Simon, have hereunto set my hand and
scal, this Tenth day of July, in the year of our Lord One thousand eight
