Improvements in Machines used as Disintegrators or Pulverizers
of Material.
I, GEORGE WILLIAM ELLIOTT, of Meersbrook Park Road, Heeley, Sheffield,
in the County of York, Mining and Mechanical Engineer do hereby declare the
nature of this invention to be as follows:-
An improved method of constructing machines used as disintegrators or
pulverizers of material.
In making or constructing a machine for the above purpose or purposes, I form
the body or casing of any suitable material, which is placed in a horizontal position,
of cylindrical configuration, open at one, or both ends, and having suitable flanges,
lugs, or similar contrivance, to which I secure, and attach the cover or covers or
ends. The said cylindrical casing is also provided with a foot or bed on, and by
which, it is secured firmly in position. On the internal periphery of this cylindrical
body or casing I place one or more metallic rings or liners, having annular webs,
formed on the inside at a suitable and approved angle to and from the said ring or
liner, in one or more pieces, or segments, and secure the same in their positions to
body or casing by any suitable mechanical means.
One cover or end form having an inlet opening, and to which may be attached
B shoot, or similar contrivance, and in the centre of said cover I provide a boss,
through which a shaft is arranged to rotate. When the body is made open at both
ends, form or provide a second cover or end, having the outlet opening in or near
the centre, and through which the beforementioned shaft may be passed, and if
required a boss or guide for the same, may be formed across the said opening or
outlet orifice.
On the outside of this cover I form or attach an extension piece or neck, of
suitable size and material placed over, and covering the outlot opening in said cover.
In this extension neck or piece, 1 form or provide an opening, opened, or closed, na
required by an adjustable shutter, alide cover, or its equivalent. To this neck or
extension piece is attached or connected, a casing, having a removable cover, and
containing a fan or similar contrivanco of approved design and construction.
In the lau casing cover, or on the periphery of the said casing, or on both, I
form or provide one or more outlets of suitable size, provided with adjustable slides
or doors.
Through the centre of the fan casing and its cover, and the cylindrical body
covers or ends, I pass a shaft which is carried and revolves in approved boarings
and is provided with a driving pulley, or other suitable arrangement for rotating
the same. Ou and secured to this shaft, and between the two cylindrical body
covers, 1 place a hollow casting or shaft formed with one or more annular webs or
flanges on the outer periphery of the same, of suitable strength. To these webs or
annular rings I attach discs, semidiscs or plates of iron, steel, or other material,
and radiating from, in line with, and attached to, the said discs or plates, or to the
hollow casting or shaft beforementioned, I form arms or beaters, of suitable size,
metallic or otherwise, which revolve or travel at, or about right angles with the
horizontal shaſt, in the annular chambers, recesses or paths formed by the webs on
the rings which are attached to the inner periphery of body casing.
In applying a modification of the before described method, the apparatus is
composed of a cylindrical casing, having a cover at each and, and fixed in a
horizontal position on a suitable bed provided, this oylindrical casing is made with
an enlarged cylindrical chamber at one end, in the periphery, or on the end of

page_text: which, an outlet is provided, the cover at the reverse end is also provided with an
inlet of suitable sizo and shape.
The driving shaft which passes through, and rotates in the beforementioned
covers is provided with a hollow shaft to which is secured by annular rims or
flanges a greater or less number of sheet iron plates, circular and vertical, provided
upon their circumference or periphery with spokes or arms of strong and rough
steel or other metal, which arms are firmly bolted thereto.
The interior of the smaller cylindrical casing is furnished or provided on the
whole of its circumference and without interruption from end to end with as many
toothed or indented pieces or annular segments as there are plates attached to the
said hollow shaft. The arms or beaters revolving in the enlarged end or chamber
are made a different and increased length and sweep to those revolving in casing of
smaller diametre. No fan is requisite in adopting this method in the construction of
a machine for the boforenamed purpose.
Suitable bearings for the shaft, and appliance for driving the same are
provided.
By another arrangement I make horizontal outer casing to consist of two semi-
cylindrical parts hinged together, the upper part (in the end of which is placed the
inlet) forins the cover of the machine. The upper and lower parts are of the same
intornal size and configuration and by means of stationary diaphragms or partitions,
are divided when the casing is closed, into two or more compartments, these
partitions or diaphragms are semiannular in shape, and conform, when closed, to a
drum or hollow casting revolving and secured to a shaft placed horizontally through
the centre of casing. A suitable space is left between the outer periphery of said
drum and the inner edges of diaphragms.
The drum or hollow shaft is provided with two or more annular discs which
revolve in the chambers, formed by the beforementioned diaphragms or partitions
in outer casing, a suitable space is also left between the edges of said discs and
the inner periphery of outer body or casing. The drum is provided with, and
secured to, metal arms or blades, which project radially from the outer periphery
of said drum and revolve in the subdivided chambers formed by stationary
diaphragms and the revolving discs secured to drum.
The outlet is formed at or near the centro of the reverse end to that having
the inlet.
A seperate casing containing a fan is provided and connected to mill by the
extension neck or piece, having the adjustable shutter or slide before described.
A shaft carrying the drum and rotating in approved bearings may be driven by
pulley or other means.
The object of my invention is also attained by constructing the body part of
metal or other suitable material, having an outer configuration similar to a cone-
pulley of approved size.
On the inner periphery of the said body I form a series of chambers or recesses
of varying diameter and sectional design which may be either formed out of, or in
the motal composing the body, or by inserting seperate and detachable rings,
sunular discs or both combined, or segments of the same, of the necessary design,
sectional or otherwise, of suitable material, the same being secured to body or
casing in their required position by screws or other equivalent.
At the smaller end of body I form or provide a suitable inlet, and shoot,
the outlet being placed at or on the larger or reverse end, or which may be formed
on the periphery of the larger diametre or in the end in any required position.
Through the centre of the body I place a shaft provided with and secured to a
boss or hollow shaft, which revolves inside the said body and to which is firmly
secured the before mentioned arms or beaters, which are of the required length
and shape to suit the various diametres of internal chambers, or recesses formed
around the inside of the body. The body or casing is provided with a suitable
foot or hed, to secure same in position, and the shaft is provided with driving
pulley and also approved bearings in which to revolve.

page_text: In this instance the centrifugal force exerted by the increasing length of arms
or beaters obviates the employment of a fan or its casings.
These machines can be made iu halves to enable auy repairs to be made in an
easy and expiditious manner, or they can be arranged to remove the ends or covera
for this purpose.
The casings may be formed by casting or built up as may be found requisite, or
advantageous, or of pressed iron or steel.

Improvements in Machines used as Disintegrators or Pulverizers
of Material.
I, GEORGE WILLIAM ELLIOTT of Meersbrook Park Rond, Heeley, Sheffield,
in the County of York, Mining and Mechanical Engineer do hereby declare the
nature of this invention and in what manner the saine is to be performed, to be
particularly described and ascertained in and by the following statement:―
An improved method or methods of constructing machines used as disintegrators
or pulverizers of material. The accompanying three sheets of drawings will
illustrate or show some of the arrangements, or combinations I employ in making
a machine for the above purpose.
The various figures or designs will be described herein, but the same letters of
reference do apply to and indicate similar parts or details in the different views
and arrangements shown.
Figure 1 Sheet 1, shews a longitudinal view, partly sectional, of a machine
formed with a cylindrical body A, of suitable material, size and strength, placed in
a horizontal position, open at both ends, and having flanges A', or if desired lugs
or similar contrivance, to which may be secured the covers or ends B, by bolts,
studs or screws.
This cylindrical body casing A, is provided with a foot or bed B¹, on which it
rests, and by which it is secured firmly in position. One cover or end I form with
an inlet opening to which may be attached a chute G, of approved shape and size,
and in the centre of said cover I provide a boss, through which a shaft J, may pass,
and revolve. When the body casing A, is made open at both ends, as shewn
I provide a second cover or end having an outlet opening at, or about, the centre
and through which the beforementioned shaft J may pass. If found requisite a
boss or guide may be formed across the said outlet orifice, to steady or carry the
said shaft J.
On the outside of this cover, placed over and covering the beforementioned
outlet opening, I form and attach an extension neck or piece D, of suitable size
and material. On the upper side, or any other suitable position of the said
neck D, I form an opening, or series of openings, and enable the same to be closed
at will, by providing an adjustable cover, slide, shutter, or its equivalent D'. To
the outer end of this neck or extension piece D, is attached or connected a
casing E, of any suitable configuration or material, having a removable cover E¹,
and containing a fan or similar contrivance F, of approved construction and
design.
In and on the periphery of the fan casing E, may be formed one or more
outlets or delivery openings H, which can be provided, if found advantageous,
with any approved adjustable slide or shutter H. If desired the delivery
openings H, may be formed in the cover E', as shown by dotted lines at H³, or
on both cover and periphery of casing. Through the centres of said covers B, B
and El, I pass a shaft of suitable strength J, which is carried and revolves in
approved bearings J', and is provided with a driving pulley K, or it may be
driven by any other mechanical appliance or arrangement.

page_text: On and secured to this shaft J, I place between the beforementioned covers B, B,
a hollow casting or shaft K', formed with, and having, on the outer periphery of
said casting, one or more annular webs Ĺ of suitable size, and to these annular
webs or flanges L, I attach and secure discs, semidises or plates L', of steel, iron
or other material. and radiating from, in line with, and attached to the said discs,
semidiscs or plates L', or to the beforementioned hollow shaft K', I form arms or
beaters M, metallic or otherwise, of suitable strength and any desired shape.
On the internal periphery of the cylindrical body or casing A, I place one or
more metallic rings or liners M', having annular wobs N, formed at any approved
and suitable angle to the said ring or liner M. These liners may be formed in
Begments or otherwise, and may be carried if desired without interruption from end
to end of cylindrical body or casing A.
The inner periphery of the said liners may be provided with a toothed, serrated
or indented surface N1, which can be carried or continued over the whole of tho
internal circumferance of said liners. The liners M', are secured in position inside
casing A, by any suitable and approved mechanical means. The arms or beators M,
attached to discs L', and hollow shaft K', revolve and travel in the paths, or
chambers and recesses, formed by the angular and annular webs N, formed on and
by the liners or rings M'.
Figures 2, Sheet 1, aro end views of the foregoing machine, and are shewn
partly in section, and Figure 3 Sheet 1, is a plan of the beforementioned sectional
and longitudinal elevation.
The object of my invention is also attained by constructing a machine, see Fig. 4
Sheet 2, having an horizontal outer casing A consisting of two semicylindrical
parts C and C, hinged together, the upper part C, in the end of which is placed
the inlet opening and chute G, forming the cover of the machine. The upper and
lower halves C and C', are of the same internal size and configuration, and
when closed, the interior is divided, by means of the stationary diaphragms or
partitions O, into two or more compartments or chambers, these partitions or
diaphragms O, aro semiannular in shape, and conform when closed to a drum,
casting or hollow shaft K', revolving and secured to a shaft J, placed horizontally
through the centre of casing A, and ends B. A suitable space or distance is left
between the outer periphery of drum or hollow shaft K', and the inner edges of the
diaphragmns or partitions O. The drum or hollow shaft K' is provided with two or
more annular discs, somidiscs, or plates L', and secured to the same by annular
flanges L, or similar means.
These discs, semidisce or plates L', revolve in the before mentioned chambers,
formed by the diaphragms or partitions O, in the outer casing A, a suitable space
or distance being left between the edges of discs L, and the internal periphery of
the outer body or casing A. The drum or hollow shaft K', has attached to it,
and provided with metallic arms or beaters M, which project radially from the
outer periphory of drum K, and revolve in the subdivided chambers formed by
the stationary diaphragms O, and the rotating discs L', attached to druin. The
outlet is formed at, or near, the centre of the reverse end to that having the
inlet and chuto G. A separate casing E, of an approved size and of suitable
material, containing a fan, or its equivalent is also provided and connected to
body portion A, by the beforementioned neck or extension piece D, provided with
the opening or openings and the adjustable shutter or slide D, as before
described.
The shaft J, carrying and actuating the hollow drum K' disc plates_Ļ', and
beaters M, revolves in approved bearings J', and may be driven by pulley K. or any
other appliance.
Figure 5, Sheet 2, shows an end view of a machine with the upper half C, thrown
open, shewing the revolving discs L', and beaters M, attached to drum K.
Figure 6, Sheet 2, illustrates a modification of the machine shown by Figure 1,
Sheet 1, and is composed of a cylindrical casing A, fixed in a horizontal position, on
a suitable bed provided, and having the cover, with the inlet opening and chute G
"

page_text: at one end as before described. The cylindrical casing A, is provided with an
enlarged eud or chamber Q, at one end, having a removeable cover E!, and in
which the outlet opening H, can be made, but the same can be provided on the
periphery of the said enlarged chamber Q, or on both as may he desired. The
internal arrangements or mechanical parts in the smaller cylindrical body A,
together with the driving or actuating portions may be the same, or similar to
that illustrated by Figure 1, Sheet 1, or Figure 4, Sheet 2, or a combination of
either, but the arms or beaters M, revolving in the enlarged chamber Q are
made a different and increased length and sweep to those revolving in smaller
casing A.
The enlarged chamber is also used for pulverizing or disintegrating material no
fan or similar arrangement is necessarilly connected to a machine of the foregoing
description.
Figure 7, Sheet 3, illustrates another method I adopt in constructing machines
for the before named purpose. By it I construct the body part or casing of metal
cast up, built up, or of stamped plates of steel or iron having an outer configuration
Bimilar to a cone pulley.
On the inner periphery of the said body or casing A I form a series of chambers
or recesses R of varying diameter, and of any desired sectional design, and which
may be either formed out of, or in the metal composing the body, or preferably by
inserting separate and detachable rings R', annular discs, or both combined, or
segments of the same, of the necessary design, sectional or otherwise, these
being secured to body casing A, in required position by screws
equivalent.
or their
At the smaller end of the body or casing I provide the inlet opening and chute G,
the outlet or delivery opening H being placed on the periphery of the largest
diameter in any required position, or if desired on the cover B, forming the end of
body A, at the largest end.
Through the centre of the body A, its small ond, and the cover B, I pass the
shatt J, provided with, and secured to a hollow shaft or casting K, and to which is
firmly secured the arms or beaters M, which are of the required length to suit the
various diameters of the internal chambers or recesses, formed by the liners or
Begments around the inside of the body A. The body casing A, is also provided
with a foot B', on, and by which, the whole is secured firmly in position. In some
instances, where the before described cone-pulley shaped body casing. A, is used, it
may be found advantageous to provide the said body casing A, with the outlet or
delivery openings, in one, or any, or all of the said various diameters, and having
adjustable shutters, grids or similar contrivance, through which the material being
operated upon may be discharged during its various stages. Theso delivery
openings with their adjustable shutters or grids may be placed or formed in any
suitable position on the periphery of the said diameters of body casing A, a driving
pulley K, or its equivalent, with approved bearings J', in which the shaft J may
revolve, is provided as shewn.
Figure 8, Sheet 3, is an end viow of the above, shewing the outlet from the
cover B, or by dotted lines from the periphery of the largest diameter of
casing A.
Figure D, Sheet 3, is a modification of the foregoing, combining the cone pulley
shaped body A, with internal segments and the revolving discs L', in addition to
the arms or beaters M.
The centrifugal force exerted by the increasing length of arms or beaters M,
obviates the employment of a fan and its casing, either combined or separate.
The adjustable valve D', in the extension neck before and herein mentioned, is
for the purpose of regulating the draught of air through the mill, thus controlling
to any desired extent the time, during which the material being operated upon
shall be subjected to the pulverizing process, and also the speed or rate of delivery
of the same.
Any of the foregoing arrangements of machines may be made in halves, to enable

page_text: any inspection and repairs to be made in an easy and expiditious manner or the
covers may be removed for this purpose.
The casings may be of cast metal, built up, or of pressed or stamped iron steel,
or other suitable material as may be found most advantageous.
