I, ALEXANDER REID MCLELLAN, of 174, Hollydale Road, Peckham, in the
County of Surrey, Engineer, do hereby declare the nature of this invention
to be as follows:
The invention relates more particularly to disintegrators or pulverizers used
for disintegrating materials which are liable to cake, such for instance, as cocoa,
wood-flour, &c.
The
The machine constructed according to the present invention consists of a
number of revolving arms or beaters rotating in a case having circular ends
and semi-cylindrical bottom, which latter is preferably corrugated or channelled.
To the ends of the case are attached a number of stationary cross cutters.
boss to which the revolving arms are attached, has a number of cutting teeth
projecting therefrom in line with the end plates, and these latter are provided
with a number of inwardly projecting cutters to act in conjunction therewith,
and have also a number of horizontally projecting cutters. The revolving arms
are arranged across the whole width of the boss, and those on the exterior pass
close to the horizontally projecting cutters on the end plates. The ends of the
revolving arms pass close to the stationary cross cutters of the case.
Each of the stationary cutters consists of two parts, one being fixed and the
other capable of receiving a short rocking motion. The moving part of the
stationary cutters approximately fits between the fixed parts thereof and prevents
the material being disintegrated from accumulating or caking between the said
cutters. The moving parts of the cutters may be operated in any convenient
manner, but I prefer to mount them on rocking shafts arranged around the case,
the said rocking shafts being simultaneously rocked by means of levers attached
by slots to a rocking disc operated preferably by an eccentric.
The apparatus above described is covered by a casing into which the pulverized
material passes.
In this casing is arranged a vertical tube capable of being
raised or lowered and having its upper end open. The finer particles of the
material rise to the top of the casing and pass down the vertical tube; the heavier
particles fall and pass again into the disintegrator through a side shoot. The
lower end of the vertical tube is arranged above a closed hopper provided at its
bottom with a valve, which latter is operated by a cam or other means so that
it opens intermittently. When it is open the disintegrated material falls into a
chamber and settles to the bottom, the air passing away through an opening in
the top thereof. The material may then fall through a valve in the bottom of
the first chamber into a second chamber, the said valve being operated in a
similar manner to the one at the bottom of the closed hopper. The material is
conveyed from the second chamber in any convenient manner.
The stationary cutters are preferably arranged radially, and the moving
portions of those cutters around the upper portion of the machine have short

page_text: teeth or projections which nearly meet each other when the moving portions are
in a central position. These short teeth or projections prevent any large particles
passing upwards.
The air escaping from the top of the first chamber above mentioned, is con-
veyed back to the entrance to the casing of the disintegrator, and is drawn
therein by the vacuum created by the revolving arms.
I mount a fork or forks on the elongation of an axis of one of the moving
parts of the stationary cross cutters, said fork or forks having consequently a
reciprocating motion and being used to regulate the feed of the material to the
machine.

Improvements in and connected with Disintegrators or Pulverizers.
I, ALEXANDER REID MCLELLAN, of 174, Hollydale Road, Peckham, in the
County of Surrey, Engineer, 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:-
The invention relates more particularly to disintegrators or pulverizers used
for disintegrating materials which are liable to cake, such for instance as cocoa,
wood-flour, &c.
I will describe my invention by means of the accompanying drawings in which
Fig. 1 is a sectional side clevation of a machine constructed according to the
invention and Fig. 2 is a section of the same drawn at right angles to Fig. 1.
Fig. 3 is an elevation showing the arrangement for rocking the movable parts
of the exterior or cross cutters and Fig. 4 is a detail view of one of the exterior or
cross cutters and Fig. 5 is a detail view of the feeding fork,
The machine constructed according to the present invention consists of a
number of revolving arms or beaters a rotating in a case having circular ends b
and bottom which latter is preferably corrugated or channelled and is formed
with two doors c hinged at (2 To the ends of the case are attached a number
of stationary cross cutters d. The boss a¹ to which the revolving arms a are
attached, has a number of cutting teeth a projecting therefrom in line with the
end plates b, and these latter are provided with a number of inwardly projecting
cutters 6 to act in conjunction therewith The end plates b may have a number
of horizontally projecting cutters as described in the Provisional Specification or
they may be formed with a rasp surface as shown in the drawings.
The revolving arms a are arranged across the whole width of the boss a¹ and
those on the exterior pass close to the horizontally projecting cutters or rasp
surface on the end plates b. The ends of the revolving arms pass close to the
stationary cross cutters d of the case.
Each of the stationary cutters d consists of two parts, one d being fixed and the
other capable of receiving a short rocking motion. The moving part d¹ of
the stationary cutters approximately fits between the fixed parts d thereof and
prevents the material being disintegrated from accumulating or caking between
the said cutters. The moving parts of the cutters may be operated in any con-
venient manner but I prefer to mount them on rocking shafts & arranged around
the case, the said rocking shafts & being simultaneously rocked by means of

page_text: levers d³ attached by slots or holes d to a rocking disc d³ operated preferably
by an eccentric e.
The apparatus above described is covered by a casing f into which the material
to be pulverized is fed by the shoot f¹ shown in dotted lines in Fig. 2. In this
casing is arranged a vertical tube 2 capable of being raised or lowered by
means of the rack 9 and pinion g¹ and having its upper end open. The finer
particles of the material rise to the top of the casing f and pass down the vertical
tube f; the heavier particles fall and pass again into the disintegrator through
a side shoot f³. The lower end of the vertical tube f2 is arranged above a
hopper through which the disintegrated material falls. The stationary cutters d
are preferably arranged radially, and the moving portions d₁ of those cutters
around the upper portion of the machine have short teeth or projections do which
nearly meet each other when the moving portions are in a central position.
These short teeth or projections de prevent any large particles passing upwards.
I mount a fork or forks g at the end of an elongation * of one of the rocking
shafts, said fork or forks having consequently a reciprocating radial motion.
They are used to assist or regulate the feed of the material to the machine.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is: :-
1. In a disintegrator, the combination of a number of revolving arms fixed on
a boss, teeth arranged on said boss in line with teeth or cutters on the end plates
and fixed cross cutters connecting said end plates each having a reciprocating
portion, substantially as herein shown and described.
2. In a disintegrator, the combination of a number of revolving arms, a case
having end plates and a fixed bottom, with a number of cross cutters attached to
the end plates each having a reciprocating portion substantially as herein shown
and described.
3. In a disintegrator the combination of a number of revolving arms, cross
cutters, end plates and fixed bottom with a casing having an adjustable tube to
carry off the finer particles and a shoot to return the larger particles to the
revolving arms, substantially as herein shown and described.
4. In a disintegrator the combination of a number of revolving arms and fixed
cross cutters arranged around said arms with reciprocating cross cutters having
projecting teeth which nearly meet when they are in the central position, sub-
stantially as shown and described.
