We, JOHN WILLIAM POPE, of 46 Ellington Street, in the County of Middlesex,
Engineer, and RICHARD POPE, of 134 York Road, in the City and County of Bristol,
Engineer, do hereby declare the nature of this invention to be as follows:-
Our invention relates to certain improvements in wet or dry pulverising machinery,
whereby the same is rendered more simple, economical in construction and maintenance,
speedy, and effective in action.
Our invention consists essentially in the combination with a suitable casing or frame
to take a ring or path of suitable metal in parts bolted together or otherwise at joints,
feed, and other parts constituting a pulverising machine, of a rotary frame cupped at
its outer edges, so as to receive a number of balls. These balls rest perfectly free in
the cups, and upon rapid rotation being imparted to the spindle of the frame, they
fly out centrifugally, and revolve against the path or ring or the casing, pulverising
any material or substance which may be descending through the machine. In order
to obviate or lessen the jar of the balls in the cups, we provide in the base of this
latter a spring or buffer of rubber or other suitable elastic material, to take the jar of
the balls. The withdrawal of the pulverising material is effected in any suitable
manner, either by exhaust or water washing through a suitable sieve or sieves, or
otherwise, and the machine is fitted with a suitable hopper and feeding apparatus and
driving gear.

page_text: We, JOHN WILLIAM POPE of 46 Ellington Street, in the County of Middlesex,
Engineer, and RICHARD POPE, of 134 York Road, in the City and County of Bristol,
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 :-
Our invention relates to certain improvements in wet or dry pulverising machinery
whereby the same is rendered more simple, economical in construction and maintenance,
speedy and effective in action.
In order that our invention may be the better understood, we now proceed to
describe the same in relation to the drawings hereunto annexed reference being had
to the letters and figures marked thereon. Like letters refer to like parts throughout
the figures.
Figure 1 represents a cross sectional elevation of our machine.
Figure 2 represents a longitudinal sectional elevation of same.
Figure 3 is a plan.
Figure 4 is a detail of the draught vanes.
Our invention consists essentially in the combination with a suitable casing or
frame A, to take a ring or path B of suitable metal in parts bolted together, or
otherwise, at the joints, feed C, and other parts constituting a pulverising machine;
of a rotary frame D mounted upon a suitable shaft E driven by the pulley F. This
rotary frame is cupped or chambered at its outer edges at G, so as to receive a number
of balls H. H. These balls rest perfectly free in the cups or chambers, and, upon
rapid rotation being imparted to the spindle of the frame, they fly out centrifugally,
and revolve against the path or ring B in the casing, pulverising any material or
substance which may be descending through the machine."
In order to obviate or lessen the jar of the balls, we provide in the base of the
cups or chambers, springs or buffers K, of rubber or other suitable elastic material
to take the jar of the balls; and, behind the path or ring we also provide a similar
spring or buffer L.
We have shown two varieties of balls one plain H and the
other H¹ formed with knobs, so as to prevent any clogging of the material against the
sides of the casing. The withdrawal of the pulverised material is effected in any
suitable manner, either by exhaust or water washing through suitable screens, sieve
or sieves, or it may be as shown, by means of a series of vanes M mounted upon the
outer side of the frame and directing the draught through a coarse mesh N and a
fine gauze screen P, the coarser material which cannot pass through the second screen
being returned to the machine through the outlet Q down the incline Q'.
The machine is fitted with a suitable hopper and feeding apparatus, which shall feed
the material to the machine at such a speed as shall prevent choking. This feed is
suitably driven from the main shaft by means of a strap R. This strap rotates a feed

page_text: shaft which by a worm & worm wheel rotates a series of arms r¹ over apertures in
the bottom of the hopper & thus feeds the material in a uniforın manner.
The sides of the cups or chambers are preferably faced with hard steel plates S,
which may be rotated or replaced on loosening the attaching nuts, to present fresh
surface to wear.
For accessibility to the interior of the machine for repairs or renewal of parts,
we close same by a bonnet T, which may be readily removed by taking off the
nuts V.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1st. The combination with a suitable casing or frame, taking a ring or path of
specially hard metal, feed, and other parts constituting a pulverizing machine;
of a rotary frame, cupped or chambered at its outer edges, and receiving any
suitable number of balls or nibbed balls, substantially as and for the purposes
specified.
2nd. The fitting of said chambers with elastic buffers, substantially as and for the
purposes specified.
3rd. The combination with a ball pulverizing machine constructed as described of
an automatically regulated feed, substantially as and for the purposes specified.
