An Improved Crushing or Pulverizing Apparatus.
1, WALTER KITTO, of 56 Claybrooke Road, Hammersmith m the County of
Middlesex Engineer do hereby declare the nature of this invention to be as
follows:-
My invention having for its purpose the crushing, pulverizing and serving
metalliferous ores, such as gold and Silver quartz 1ock, cements, limes, plasters,
alabasters, kaolin, bones, oxides and other hard substances by either wet or dry
systems It can also be used in the crushing and mixing of moist and plastic
materials, refining of paper pulp, and in milling for regrinding bran and meal.
It consists of a cylindrical casing in which a horizontal ng or crushing path of
hard metal or other suitable material, having a specially formed internal face
against which the sphere 18 made to rotate and crush the material by centrifugal
force by a quick rotary motion transmitted through a bell shaped or other suitable
formed propeller and friction contact.
The null is actuated by a vertical shaft, pulley and belt or any other suutable
manner, on the top of the vertical shaft is fitted a clutch having a ball bearing,
caying and during the bell shaped or other suitable formed propeller which
transmits the centrifugal motion to the crushing sphere by friction contact.
The ball clutch and bell shaped or other suitable formed propeller 18 hold
together by a uut and plate on the top of the vertical shaft, between the plate and
the propeller is placed a spring, rubber buffer, or any other suitable contrivance to
give elasticity to the propeller.
The sphere to be of cast iron or other suitable material, the surface of which to
be smooth, groved or with other stable indentations to suit the nature of the
materials under treatment.
The cylindrical casing is provided with suitable outlets fitted with screens for wet
crushing through which the pulverized material 18 washed. In dry crushing the
material after beeu pulverized is exhausted from the machine by a fan or other
suitable means and delivered into specially arranged depositing chambers.
In crushing gold quartz ore by the wet system I arrange, in the interior of the
mill, copper plates and au annular resei voir for containing quicksilver to retain the
heavy gold in the mill.
The cylindrical casing 18 fitted with a suitable cover to prevent the escape of any
material under treatment and arranged so that it can be quickly removed to allow
access to the interior for examination. The side of the mill casing 18 provided
with a suitable inlet through which the material is fed into the mill by an automatic
feed arrangement after it has been reduced to a suitable size by a breaker or other
means.

page_text: 1, WALTER KITTO of 21, Westcroft Square late of 56, Claybrooke Road,
Hammersmith, in the County of Middlesex, Engineer, do hereby declare the
nature of this mvention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement
-
My invention having for its purpose the crushing, pulverizing and sieving
metalliferous ores, such as gold and silver quaitz 1och, cemment limes, plasters,
alabastere, kaolin, bones, oxides and other hard substances by either wet or dry
systems.
It can also be used in the crushing and mixing of moist and plastic
materials, refining of paper pulp, and in milling for reginding bran and meal
It consists of a cylindrical casing in which is a horizontal ting or crushing path
of hard metal or other stable material having a specially formed internal face
against which a sphere is made to rotate and crush the material by centrifugal
force, motion being transmitted to the sphere through the frictional contact of a
bell shaped or other suitably formed propeller driven from a vertical shaft by means
of a ball-shaped friction clutch controlled by suitable spings.
In the accompanying diawing which illustintes my improved apparatus.
Figure 1 is a view in elevation-partly in section, and
Figure 2 18 a view in plan.
In both views similar parts are marked with like letters of reference.
In a suitable cylindrical casing A is fixed a ring B of steel or other hard metal
o material forming a cushing path. The sphere C which is adapted to rotate
against the inner face of the ring B is duiven-by fictional contact by means of
a bell or coned shaped propeller D driven by a vertical shaft E mounted in suitable
bearings a a in the casing A and being provided with a pulley e by means of which
rotary motion is imparted to it from any suitable source of power. The bottom
edge d of the propeller D is faced or formed to a suitable angle to engage with
the sphere C. The propeller Dus mounted on the shaft E by means of a ball and
socket joint the ball part F being fixed on the shaft and the socket part F being
formed on or attached to the propeller D. The parts F and F are kept engaged
by a series of springs or buffers G which form a fiction clutch and give elasticity
to the propeller. The clasticity of the spings or buffers is controlled by the
Duts & threaded on to the top end of the vertical shaft E
The sphere C may be of cast iron or other suitable material, and its surface may
be smooth, grooved or with other suitable indentations to suit the nature of the
materials to be treated
The cylindrical casing A is provided with suitable outlets fitted with screens
such as 11 for wet cushing through which the pulverized material 13 washed. In
dry crushing the material after being pulverized is exhausted from the machine
by a fan or other suitable means and delivered into specially arranged depositing
chambers.
In crushing gold quartz ore by the wet system I arrange in the interior of the
mill-in the well-knownmanner-copper plates and an annulai reservoir for
containing quicksilveu to retain the heavy gold in the mill.
The cylindrical casing is fitted with a suitable cover J to provent the escape of
any material under treatment and arranged so that it can be quickly removed to
allow access to the interior for examination. The side of the mill casing is
provided with a suitable inlet K through which the material is fed into the mill
after it has been reduced to a suitable size by a breaker or other means.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what [
claim is :-
(1.) The improved crushing or pulverizing apparatus substantially as herein-
before described and illustrated by the accompanying drawing.
(2.) In a crushing or pulverizing apparatus in which the crushing or pulverizing
is effected by a rotating sphere, imparting rotary motion to the said sphero by
means of a hanging propeller carried and driven by a central vertical shaft as
hereinbefore described and illustrated by the accompanying drawing.
(3.) In a cushing or pulverizing apparatus in which the crushing or
pulverizing is effected by a rotating sphere, the combination with the sphero of a
crushing path consisting of a ring of steel or other suitable hard metal or material
fixed in a cylindrical casing, and of a propeller adapted to dive or rotate the sphere
by frictional contact, the said propeller being connected to the driving shaft by
menus of a frictional ball and socket joint, as and for the purpose set forth.
