PROVISIONAL SPECIFICATION.
An Improved Crushing, Grinding, or Mixing Machine.
I, MAXIME HUBERT SIMONET, of Quintin (Cotes-du-Nord), in the Republic
of France, Paper Manufacturer, do hereby declare the nature of this invention to
be as follows:
This invention relates to the construction of an improved machine for crushing,
grinding, or intimately mixing substances of all kinds.
In carrying out the invention I construct the apparatus of two cylinders placed
side by side and provided with longitudinal projecting ribs which are so arranged
that at one part of the cylinders there are four ribs, at another part eight, and at
another part sixteen, at which parts (when the machine is used in the manufacture
of paper) the respective operations of rough or first grinding, and the conversion of
the material into half stuff and stuff takes place.
Each cylinder is surrounded by a shell or casing contained within a double
cylindrical box and provided on its inner surface with suitably arranged projecting
ribs these shells or casings are adjustable by means of adjusting screws whereby
the distance apart of the cylinders and casings may be regulated and a greater or
less amount of friction be obtained according to requirement.
At the point of intersection of the two casings containing the cylinders is a
groove which contains a longitudinal adjustable blade forming a knife which bears
against the whole length of the two cylinders and cuts the substance introduced into
the machine.
Suitable openings are provided for the material to be fed into the machine and
for its discharge therefrom.

COMPLETE SPECIFICATION.
An Improved Crushing, Grinding, or Mixing Machine.
I, MAXIME HUBERT SIMONET, of Quintin (Cotes-du-Nord), in the Republic
of France, Paper Manufacturer, 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 :-
This invention relates to the construction of an improved machine for crushing,
grinding, or intimately mixing substances of all kinds, which can be advantageously
employed in paper manufactories, oil mills, or for the manufacture of briquettes or
agglomerated fuel.
In order to enable the invention to be fully understood I will describe the same
by reference to the accompanying drawing in which:
Figure 1 is a perspective view of the improved machine in its open position and,
Figure 2 is a transverse section of the machine when closed.
To a frame A. is adapted a double cylindrical box or case B the top part of
which can be opened and in which are placed two movable shells or casings C
adjustable in position relatively to the cylinders D and D' by means of regulating
screws V.
The surfaces of the cylinders D and D' are provided with longitudinal projecting
ribs the number of which is increased towards the opening E.

page_text: The two cylinders are mounted on shafts working in the frame A and held in
their bearings by plates G provided with lubricators g.
The movable shells or casings C are of cast steel and have formed on their inner
sides and integral therewith a number of ribs which owing to their angle of
inclination carry along the substance to be crushed or ground a shearing action being
produced by the moving against one another of the spiral ribs of the two
cylinders D D'.
At the point of intersection of the two chambers forming the double box in
which the cylinders are placed is a groove which contains a longitudinal knife-
blade R adjustable by means of screws placed beneath the double box this blade R
cuts the material brought along by the teeth or ribs of the cylinders.
The machine is operated by pulleys, the driving belt from which passes through
a belt-shipper I, fixed to a rod sliding in a support K fixed to the frame of the
machine. One of these pulleys His loose and the other is keyed on a shaft Lon
which is fixed a pinion M which engages with a toothed wheel N fixed on the
cylinder D. The pinion M driven from the pulleys H operates the toothed wheel N
keyed on the shaft of the cylinder D'. This cylinder communicates movement to
the cylinder D by means of its helicoidal ribs which gear with the helicoidal ribs
of the cylinder D.
The operation of the machine will be understood by referring to the drawing.
The movable part of the case B being turned down and fastened to the fixed part
the substance to be operated upon is caused to enter through a conduit or pipe
which conveys it to a receiver of suitable form fixed to the inlet P whence it falls
onto the ribs which at this point are somewhat wide apart and is then cut and
ground between these ribs and those of the movable shells C and the longitudinal
knife or blade above referred to, at the same time continuing to travels towards the
ends of the cylinders where there are a larger number of ribs, and finally passing
out through the opening E either direct into a suitable receiver or through a pipe
or channel.
It will be obvious that the number of ribs carried by the cylinders and movable
shells respectively and their angle of inclination can be varied according to
requirement.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what mauner the same is to be performed, I declare that what I
claim is
1. A crushing, grinding or mixing machine comprising a double cylindrical box
or case provided with two movable adjustable shells having ribs on their inner sides
for crushing or grinding the material in connection with two cylinders also provided
with ribs, substantially as herein before described.
2. In a machine of the kind referred to in claim 1 the use of a longitudinal knife
or blade for cutting and separating the substance drawn through the two cylinders,
substantially as hereinbefore described.
3. The improved crushing, grinding, or mixing machine hereinbefore described
and illustrated in the accompanying drawing.
