I, WILLIAM BOULTON, of Providence Foundry, Burslem, Staffordshire, Engineer,
do hereby declare the nature of the said Invention, to be as follows :-
This Invention relates to improvements in or applicable to machinery for disinte-
grating or pulverising hard and soft materials, being specially applicable for pulverising
materials used in the manufacture of tiles and pottery-ware.
In accordance with the present improvements the machinery is so constructed as
that the object of the Invention is obtained by the combined effects of centrifugal
impulsion against and impact with relatively fixed parts of the apparatus substantially
in the manner hereinafter described.
The improved apparatus is constructed with a feeding hopper which is surmounted
by suitable bearings carrying the feed actuating details which consist of a driving
spindle carrying a pulley operated by a strap, and a worm which actuates a worm
wheel fast on a vertical shaft, which descends through the hopper, and a stuffing box
at the bottom thereof, and is supported by such bearings, and by a footstep.
The said shaft carries a series of fixed knives, cutters, or equivalent parts, which
are rotated by the above described means or by equivalent means within the hopper,
in such a manner as to tend to cause a constant downward feed of the material being
operated on through a grated bottom adapted to the lower part of the hopper, and a
lateral delivery of the material which passes through such grating through a side
outlet to the disintegrating or pulverising chamber.
The upper part of the disintegrating or pulverising chamber is made of an excentric
or enlarged formation relatively to the lower part thereof, and is adapted with a
removable hard or hardened part or parts, and such upper parts of the chamber are
so disposed relatively to a series of arms or beaters rotating within the chamber, as
that owing to the centrifugal force imparted to the material being operated on by the
rapid rotation of the said arms or beaters, the material as it begins to traverse such
enlarged part of the chamber escapes from the control of the said arms and flies with
the acquired momentum against the said hardened part or parts, the impact with

page_text: which is of considerable effect in breaking up the parts so impelled, and which parts
then fall into the lower part of the chamber which is made of a concentric formation
relatively to the centre of actuation of the arms or beaters, and is formed as a grating
through which the arms or beaters as they rotate continuously press the material
when sufficiently pulverised. The grated bottom of the chamber can be conveniently
got at from the outside through openings between the supporting framing of the
chamber, and the escaping pulverised material falls through a bottom opening made
in the sole or bed plate of the machine.
The arms or beaters are mounted fast on a shaft which passes through the said
chamber and is supported by external bearings rising from and cast on or bolted to
the sole plate (which also supports the framing of the chamber and the footstep of the feed
shaft) and is fitted with a pulley by means of which the said shaft and arms or beaters
thereon are operated.
In operating upon hard materials such as calcined flint, stone, or old saggars, I
prefer to use a disintegrating arrangement in which the rotating arms or beaters are
slotted at their outer ends, and are adapted with rollers of any suitable shape which
carry the material round with great force causing it to be broken up by impact with
the said fixed part as aforesaid, and subsequently grind and pulverise it against and
force it through the grated bottom of the chamber, the slotted ends of the beater arms
allowing of the rollers yielding according to the sizes of the parts of the material
being operated upon.
In operating upon soft materials such as clay dust for tiles or other articles, either
dry or damp, I prefer to use a disintegrating arrangement in which a greater number
of rotating beater arms is used, the arms or beaters not being adapted with the
pulverising rollers, and in which the disintegrating part (or parts) consists of a series
of depending fixed studs or projecting parts which may be of a flat, round or other
shape, and may be variously arranged.
If the disintegrated or pulverised material is required in a damp condition, water
may be introduced into the hopper as required, or the material may be damped before
being fed into the hopper.

Improvements in or Applicable to Disintegrating or Pulverising
Machinery.
I, WILLIAM BOULTON, of Providence Foundry, Burslem, Staffordshire, Engineer,
do hereby declare the nature of my said 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 improvements in or applicable to that class of machinery
for disintegrating or pulverising hard and soft materials wherein the said object is
obtained by the combined effects of centrifugal impulsion of the materials being
operated on against and impact with relatively fixed parts of the apparatus.
On the accompanying drawings,
Fig. 1 represents a sectional elevation of disintegrating or pulverising machinery
constructed and operating in accordance with the present improvements; Fig. 2,
represents a sectional plan view of Fig. 1, through about the line a-b; Fig. 3,
represents a side elevation of the apparatus; and Figs. 4, and, 5, represent sectional
elevations of the disintegrating or pulverising parts of the apparatus.
The improved apparatus is constructed with a feeding hopper. 1, which is sur-
mounted by suitable bearings, 2, carrying the feed actuating details which consist of
a driving spindle, 3, carrying a pulley, 4, operated by a strap, and a worm, 5, which
actuates a worm wheel, 6, fast on a vertical shaft, 7, which descends through the
hopper, 1, and a stuffing box, 8, at the bottom thereof, and is supported by such
bearings, 2, and by a footstep, 9.
The shaft, 7, carries a series of fixed knives, cutters, or equivalent parts, 10,
which are rotated by the above described means or by equivalent means within the
hopper, 1, in such a manner as to tend to cause a constant downward feed of the
material being operated on through a grated bottom, 11, adapted to the lower part of
the hopper, and a lateral delivery of the material which passes through such grating
through a side outlet, 12, to the disintegrating or pulverising chamber, 13.
The upper part, 13*, of the disintegrating or pulverising chamber, is made of an
excentric or enlarged formation relatively to the lower part thereof, and is adapted
with a removable hard or hardened part or parts, 14, and such upper part of the
chamber, 13, is so disposed relatively to a series of arms or beaters, 15, rotating
within the chamber, as that owing to the centrifugal force imparted to the material
being operated on by the rapid rotation of the said arms or beaters, the material as it
begins to traverse such enlarged part of the chamber escapes from the control of the
said arms and flies with the acquired momentum against the said part or parts, 14, the
impact with which is of considerable effect in breaking up the parts so impelled and
which parts then fall into the lower part of the chamber, 13, which is made of a con-
centric formation relatively to the centre of actuation of the arms or beaters, 15, and is
formed as a grating through which the arms or beaters as they rotate continuously
press the material when sufficiently pulverised. The grated bottom of the chamber

page_text: can be conveniently got at from the outside through openings, 16, between the
supporting framing 17, of the chamber; and the escaping pulverised material falls
through a bottom opening, 18, made in the sole or bed plate, 19, of the machine.
The arms or beaters, 15, are mounted fast on a shaft, 20, which passes through the
chamber, 13, and is supported by external bearings, 21, rising from and cast on or
bolted to the sole plate, 19, (which also supports the framing of the chamber, 13, and
the footstep of the feed shaft, 7,) and is fitted with a pulley, 22, by means of which
the shaft, 20, and arms or beaters, 15, thereon are operated.
In operating upon hard materials such as calcined flint, stone or old saggars, I
prefer to use the disintegrating arrangement illustrated in Fig. 5, in which the
rotating arms or beaters, 15, are slotted at their outer enis, 23, and are adapted with
rollers, 24, of any suitable shape which carry the material round with great force
causing it to be broken up by impact with the said fixed part, 14, as aforesaid, and
subsequently grind and pulverize it against, and force it through the grated bottom of
the chamber, 13, the slotted ends of the beater arms allowing of the rollers yielding
according to the sizes of the parts of the material being operated upon.
In operating upon soft materials such as clay dust for tiles or other articles, either
dry or damp, I prefer to use the disintegrating arrangement illustrated in Fig. 4, in
which a greater number of rotating beater arms is used, the arms or beaters not being
adapted with the pulverising rollers, and in which the disintegrating part (or
parts) 14, consists of a series of depending fixed studs or projecting parts which
may be of a flat, round or other shape, and may be variously arranged.
If the disintegrated or pulverised material is required in a damp condition, water
may he introduced into the hopper, 1, as required, or the material may be damped
before being fed into the hopper.
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 1
claim is
1. The construction of machinery for disintegrating and pulverising hard and soft
materials by the combined effects of centrifugal impulsion against and impact with
relatively fixed parts of the apparatus, in the improved manner hereinbefore described.
2. The combination with such machinery of feeding mechanisin constructed and
operating in the improved manner hereinbefore described.
3. The construction and operation of such feeding mechanism substantially in the
improved manner hereinbefore described.
