WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London "IMPROVEMENTS IN DISINTEGRATING MACHINES
Communicated to me from abroad by Silas Dodson and Evan Buckalew Dodson
both of the City and State of New York, United States of America,
This invention relates to disintegrating machines.
The said invention partly consists in the combination of a rotary part and a
fixed abutment composed of sections and serving to disintegrate between them the
material to be treated, the said rotary part having V shaped circumferential ribs or
projections and the said abutment having corresponding V shaped grooves which,
at the bottom are closer to the said ribs or projections than at the' top and extend
outside the sides of the rotary part with devices for adjusting and securing said
abutinent.
It also partly consists in the combination of a rotary part and a fixed abutment
composed of sections having angular faces provided with teeth extending transversely
to the width, the said sections being in contact at the inner edges.
It also partly consists in the combination of a rotary part and a fixed abutment
composed of a number of separate sections bolted together, a slideway in which
the said abutment is fitted, a screw whereby they may be adjusted into different
positions and a screw whereby they may be clamped in position.
It also partly consists in the combination of an abutment and a rotary part
composed of separate discs fitted on a shaft against a collar and secured by a nut
screwed on the shaft.

mounted on a shaft whose journals are furnished with collars which fit in grooves
in their bearings.

In the accompanying drawing,
Figure 1 is a vertical section of a machine constructed according to this
invention;
Figure 2 is a top view or plan of the same with the top of the case removed and
the hopper in section; and
Figure 3 is a sectional elevation of the same at right angles to that of Figure 1.
Similar letters of reference indicate corresponding parts in the several figures
A A' indicate the case of the machine which case is composed of a lower base
portion A and an upper removable portion A¹. This case is provided with a
hopper B B which as here shown, is made in two sections, the upper being
attached to, or made integral with, the upper section of the case, and the lower
being made separate therefrom. The upper section of the hopper is provided with
a sliding gate B2 whereby the passage of material through it may be controlled.
The gate is connected by a link B³ to a hand lever B
CC C² indicate a stationary abutment, here shown as composed of three sections
connected by a bolt D. This abutment is supported in a bearing or slide-way a in
the lower section of the case. Against its outer end impinge screws b whereby it
may be adjusted inwards. If desired, one screw only may be used. On the top of
the abutment bears a set screw c whereby the said abutment may be clamped
rigidly in the different positions to which it may be adjusted.
As the sections of the abutment are held together by the bolt D, only one set
screw c is necessary to hold them in place after adjustment.
This abutment has V shaped grooves forming a series of inclined sides or faces d
which have angular arc-shaped profiles. On these sides or faces are teeth d' which
extend.transversely to their width or in other words from the outer to the inner
edges. The inclined faces of the different sections meet at the base of the grooves.
E E' indicate a rotary part composed of two discs or sections mounted on n
shaft F. This shaft is provided with a collar F against which one of these
sections bears, and a nut F2 screwed on the shaft bears against the other of the
sections, whereby the said sections are secured in position. The journals of the
shaft fit in bearings formed partly in the lower section and partly in the upper
section of the casing and are furnished with collars e which enter grooves and so
serve to steady the shaft in its movements
The sections of the rotary part have a circular profile, and V-shaped circum-
ferential ribs or projections forming bevelled sides or faces f, extending into
proximity to the sides or faces of the abutment. The arc-shaped profile of the
abutment is arranged excentrically to the profile of the rotary part, so that between
the two parts will be left a space which will contract or decrease in size down-
wardly. The face of the abutment is very short and is arranged at a considérable
distance above the lower side of the rotary part so that the disintegrated material
may drop freely from the machine and thus be delivered by gravity alone.
bevelled faces d which are nearest opposite sides of the abutinent, overlap or fit
outside the bevelled faces on the outer sides of the rotary part E E.
The
As the abutment has a rectilinear adjustment towards and from the rotary part,
the degree of excentricity of its face relatively to the rotary part will be substan-
tially the same, no matter at what distance from the rotary part its face. is. The
bevelled sides or face of the rotary part are provided with teeth f, preferably
arranged reversely to the teeth of the abutment. These teeth extend transversely
to the width of the sides or in other words from the outer to the inner edges.
The material to be disintegrated is introduced into the hopper and is disin-
tegrated in its passage between the abutment and the rotary part. The degree
of fineness of the disintegration may be varied by adjusting the abutinent. The
material disintegrated may pass through the opening g in the lower section of the
case into any suitable receptacle.

page_text: This machine may be used for disintegrating grain, ores, or other materials.
The sections of the rotary part E E' are preferably made of cast steel; but the
sections C C C of the abutment may, with advantage, be made of cast steel or of
stone, or, in some cases, of wood.
Having thus fully described the said Invention as communicated to me by my
foreign Correspondents, and the manner of performing the same, I wish it understood
that I claim in a disintegrating machine:-
First The combination of a rotary part and a fixed abutment, composed of
sections, and serving to disintegrate between them the material to be treated, the
said rotary part having V-shaped circumferential ribs or projections, and the said
abutment having corresponding V-shaped grooves, which at the bottom are closer
to the said ribs or projections than at the top, and extend outside the sides of the
rotary part, and devices for adjusting and securing the said abutment, substantially
as specified.
Second-The combination of a rotary part and a fixed abutment composed of
sections having angular faces provided with teeth extending transversely to the
width, the said sections being in contact at the inner edges substantially as
specified.
Third The combination of a rotary part and a fixed abutment composed of a
number of separate sections bolted together, a slide-way in which the said
abutment is fitted, a screw whereby the said sections may be adjusted into different
positions, and a screw whereby they may be clamped in position, substantially as
specified.
Fourth-The combination of an abutment and a rotary part composed of
separate discs fitted on a shaft against a collar and secured thereon by a nut
screwed on the shaft, substantially as specified.
Fifth-The combination of an abutment, and a rotary part mounted on a shaft
whose journals are furnished with collars which fit in grooves in their bearings,
substantially as specified.
In Witness whereof I the said William Robert Lake have hereunto set my
hand and seal this twenty fourth day of March in the year of our Lord One
thousand eight hundred and eighty three.
