Disintegrating Coke and other Materials.
We JULES JOLY and JULES BOCHON both of St. Ghislain, Belgium, Engineers 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:
Our invention refers to an apparatus or machine for granulating or disintegrating
coke and other materials.
The invention will be best understood by describing same with reference to the
accompanying drawings. Figure 1 is a longitudinal vertical section of the machine,
and Figure 2 is a horizontal section through the line e, y, of the same and Figure 3
is a plan view of one half of the apparatus with top cover removed.
Figures 4 and 5 are diagram views of modified forms of the knife carrier and case.
As will be seen by reference to the drawings, the apparatus is composed of a circular
funnel shaped box or case A in which there are a series of revolving superposed
discs B and forming when coupled or combined together the frustrum of a reversed
conc, the section of which gives an angle smaller than that given by the section of
the box or case A so that the upper part of the cone B B B may be further from the
side of the box A than the lower part.
The reversed cone before mentioned in the interior of the box A is formed of a
succession of superposed discs B; these discs B are trapezoidal in section, and hold or
secure between them the knives C provided with an aperture so as to be held between
each disc by means of one or several pins O so fixed as to correspond with a hole in
the base of the disc which comes immediately above it.
These discs B B B, the number of which may vary, are held and maintained one
from the other by a central shaft b pivotted and working in a socket at its lower end.
This shaft serves to transmit to the said discs a rapid rotary motion. As clearly shown
in the drawing see Figures 1 and 3 the series of discs B has four spindles or rods
passing through them on which there are springs E E E E E bearing or pressing on
each disc with the object of sensibly distancing one from the other when it is desired
or required to remove or to change the knives CC. This part of the section of the
cone (that to the right) does not show the knives because in Figure 1 we have supposed
them to be all placed directly one above the other (the number may vary, we have

page_text: however shown five for the two first discs, 4 for the following and three for the last)
whilst in Figure 3 the plan of the cone B B shows the knives placed on a line at an
acute or obtuse angle with the base of the cone.
We do not limit ourselves to this one form of reversed frustrated cone given to knife
carriers B, and funnel shape to the casing A as we may make both of them cylindrical,
as for example is shown by the diagram Figure 4, or one. may be cylindrical and the
other conical as shown by the diagram view Figure 5. In the first case the knives
are placed so as to form an angle with the side of the case.
The apparatus may be made of any required size.
From the preceding description it will be easy to understand that according to the
degree of fineness it is required to reduce the material, the position of the knives C C
should be modified or varied with respect to their distance from the side of the box A
by raising or lowering the central shaft carrying the discs B B. The material to be
disintegrated or ground is introduced into the apparatus by the hopper K Figure 1,
from whence it falls into the part left free between the series of discs and the side of
the box A. The knives CCC being supposed to be in the position (see particularly
Figure 3) the smaller pieces of material will fall to the bottom and the larger pieces
will be retained by the first series of knives and that gradually until they are reduced
by being broken up and forced to descend from knife to knife and to leave the
disintegrator by passing by the series of knives of the lower plate the distance of which
from the end of these to the side of the box A gives exactly the size to which it is
required to reduce the material.
After having passed by the last series of knives or at any rate through the space left
free between these and the side of the box A. the granulated or disintegrated material
falls on to a plate H see Figures 1 and 2 which plate is circular and keyed on to the
central shaft b. The plate H receives a rotary motion corresponding with that of the
reversed cone B B B and it is provided with several angle pieces II forming vertical
projections thereon.
These angle pieces I I are intended to throw the granulated material which the
plate H receives against a circular grating G composed of a succession of vertical blades
JJJ placed one alongside the other and spaced according to the size to which it is
desired to reduce the material to be granulated or disintegrated and which corresponds
with the space left clear between the last series of knives and the side of the box A.
The object of this arrangement of plate H and grating G is only to allow finally to
leave the apparatus or machine such of the granulated material as has been reduced to
the required dimensions and it is to some extent the regulator of the machine.
In fact in the event of a piece of material having passed the last series of knives C
(a thing possible in case a flat or long surface might be presented) it will be forcibly
thrown against the grating G where it will be broken up and finally its parts will pass
between the blades J J and from thence to fall on an inclined plate L which will
conduct it with the rest of the granulated or disintegrated material out of the
apparatus or machine.
The grating G may in relation to the axis of the plate be formed with partly diagonal
or radiating blades. These blades J J are movable and can be removed, brought
nearer to, or distanced from one another as required-see the section Figure 1.
The vertical shaft Figure 1 is pivotted at M in a step which slides so that its
position may be adjusted by raising or lowering same by means of a screw N or other
convenient means.
The box A Figure 1 is provided with a door F opening outwardly so that the inside
of the machine may be examined when required for changing the knives and for other
purposes.
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 combination and arrangement of the disintegrating or granulating
apparatus or machine substantially as described and illustrated with reference to the
accompanying drawings.

page_text: Second In disintegrating or granulating machines, the application of a series of
dises forming by their combination a frustrum of a reversed cone provided with
projecting knives throughout the surface thereof, the object being to break, granulate,
pulverize or disintegrate such as coke, coal or other materials by combination with an
enclosing chamber, box or drum, a section of which forms an angle greater than that
formed by the said frustrated cone substantially as and for the purpose hereinbefore
described with reference to the accompanying drawings.
Third: The means employed for adapting the cone to carry knives, and the combi-
nation of the rods for holding the discs composing the said cone with the object of
separating them when desired by means of the action of expansile springs carried by
the said rod all substantially as before described and illustrated with reference to the
accompanying drawings.
Fourth The means employed for raising and lowering the cone for diminishing or
increasing the angle formed with it, and the box or drum or case substantially as herein-
before described and illustrated with reference to the accompanying drawings.
Fifth The combination with the said apparatus of a plate with vertical projections
therein having a rotary motion imparted to same with the object of controlling or
regulating the work of the granulating cone by forcing the two large parts or granules
to be broken against a vertical circular grating acting as a sieve as before described,
without specially claiming the said plate but only its application to the apparatus or
machine all substantially as hereinbefore described and illustrated in the accompanying
drawings, together with any mere modification or modifications thereof.
