PROVISIONAL SPECIFICATION.
A Crusher and Pulveriser.
I, WILLIAM COLIN MORISON 1 Albert Square Great Yarmouth Gentleman do
hereby declare the nature of this invention to be as follows :-
It consists of a stationary vessel with a nearly semispherically shaped bottom and
sides extending upwards, and inclining outwards, from the upper portion of said
hollow bottom through the centre of which a circular hole is formed of a diameter
nearly, or equal to, that of a circular hole formed in the central portion of the
semispherically shaped lower end of a circular solid piece which end duly fits and
works upon the bottom of said vessel. The sides of said piece are suitably inclined
outwards as they are extended upwards so that as the lower end of said piece rests'
upon the bottom of the vessel and the said piece is suitably inclined towards the
side of the vessel and duly rolled round the interior of the vessel rock will be duly
broken between the inclined side of the piece and the side of the vessel.
In pro-
portion to the smallness said rock is broken it is free to drop downwards into a
gradually diminishing space between the side of the piece and the side of the
vessel until it reaches the lower end of said piece where it is subjected to a grinding
action and is gradually carried towards and to the lower portion of the vessel where
it is caught by the inner edges of the hole in the piece and duly discharged through
the hole in the bottom of the vessel owing to the rolling action in the inclined
position of said piece. The hole in said piece is duly connected with openings in
the upper portion of the piece to allow air to enter it and of its being freed when
choked; due provision is also made to free the hole in the bottom of the vessel
should it becoine choked.
The rolling action is communicated to said piece by means of the upper end of a
shaft which extends upwards from the top of said piece being duly connected with
the outer end of a horizontal arm fixed to and extending from a revolving vertical
shaft over and in line with the axis of the vessel. The incline of the piece can
readily be regulated by the degree to which the upper end of its shaft is placed
towards the outer end of said arm.
With the view of lessening weight in said piece it is not heavy enough to enable
its weight to be depended upon to maintain it in suitable position when working but
it is kept as required by the upper end of the shaft extending upwards from said
piece being duly connected with, and prevented from rising by the lower end of a
piece inclining downwards from and duly connected with the upper portion of said
revolving shaft the upper end of which revolves against suitable discs suitably
placed in a rigid frame which resists the upward thrust resulting from the action
of crushing and pulverising said rock. Said piece is suitably covered, and the
vessel suitably lined, with proper hard metal.

WILLIAM COLIN MORISON 12 The Plain, Mutley, Plymouth late of 1 Albert
Square, Great Yarmouth Gentleman, do hereby declare the nature of my invention
for Crushing and Pulverising Rock or other suitable material and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
It consists of an upright stationary vessel a, see Fig. 1. with a nearly semi-

page_text: spherically shaped bottom and sides extending upwards and inclining outwards
from the upper portion of said bottom through the centre of which a circular hole b
is formed of a diameter nearly, or equal to, that of a circular hole c formed in the
central portion of the nearly semispherically shaped lower end of a circular duly
covered piece d the lower end oi which duly fits loosely and works upon the bottom
of said vessel.
The piece d is suitably formed so that as its lower end suitably fits the bottom
of the vessel and d is suitably inclined towards the side of the vessel and duly
rolled round in the vessel rock will be duly broken between the piece d and the
vessel. In proportion to the smallness said rock is broken it is free to drop
downwards into a gradually diminishing space between the piece d and the side of
the vessel, until it reaches the lower end of said piece where it is subjected to a
grinding action and is duly carried towards and to the lowest portion of the vessel
where it is caught by the inner edges of the hole c in the piece d and duly
discharged through the hole in the bottom of the vessel owing to the rolling
movement in the inclined position of said piece d.
end
The rolling movement is communicated to the piece d by means of the upper
of the shaft g, which is fixed to and extends upwards from the top of d, being free
to revolve in bearings which are maintained in position between two parallel
somewhat horizontal arms (see Fig. 3) with vertical faces, one arm being on each
side of and nearly equally distant from the axis of, and duly connected with the
lower end of, the vertical shaft which is over and in line with the axis of the
vessel, and of which arins one duly pushes said bearings in a circular direction.
The shaft g with the piece d are duly inclined and maintained in position when
revolving by centrifugal action and the inclined surface p formed on the lower
portion of each of said arms resting respectively upon the surface q' formed, one on
each side of the shaft g, on the upper portion of through which g is passed. On
the lower portion of 9, on each side of the shaft g, is formed a piece to fit circularly,
while capable of oscillating moderately, in a suitable recess, one on each side of g,
formed on the upper portion of the circular piece the lower portion of which duly
fits and rests upon the upper one of several somewhat conically shaped friction
rings, as shewn in dotted lines, which work in a recess formed round the lower end
of the shaft g. Thus the weight of the shaft n and its connections are duly brought
to bear upon said rings and the piece d which thus is not held rigidly in any
position.
Said rings are duly covered by the caps which encircles and is screwed to the
upper portion of the outer surface of said recess; said cap is shewn in section.
The shaft n is duly maintained in position by its bearings and rotated by means
of the pulley v. The arms pare duly formed in a braced covered circular piece w
fixed to the lower end of the shaft n and round the outer portion of which is fixed
and extends downwards from it a conically shaped piece x much of which and also
much of said piece w including one of the arms is broken off so as the better to shew
the connections of the bearings of J.
The frame y is bolted to the frame y¹ which is bolted to the frame which
contains a layer of soft metal a¹ in which the vessel a which is of hard metal fits
securely.
The piece d is formed, say, of ordinary cast iron but is duly covered with a layer
of soft metal over which the hard metal pieces d', c¹, e', duly fit.
The hole e duly connects with the passages e and fleading to the upper portion
of d to enable c to be readily cleaned out should it become choked.
The shaft g shewn in Fig. 3 in a vertical position works in bearings similar to
ordinary journal boxes, half on each side of the shaft but they are respectively
adjusted and maintained in position by a plate at their backs fixed respectively to
the strap pieces h h and i, i, k, k, which are suitably provided with gibs and the
keys, m, m, each of which is suitably furnished at its upper end with a lug through
which are passed respectively the two bolts o, o, which respectively fit into i, i, so
that as said bolts are duly turned round they duly force the keys downwards

page_text: between the gibs and cause the two plates to approach each other and enable the
said bearings to be duly adjusted to the shaft g, said bearings rest respectively on
a curved piece formed, on each side of the shaft g, on the upper surface of q.
The bearings, t, t, and, u, u, are formed half on each side of the shaft but the two
halves, t, t, with the two side pieces, t¹, u', shewn on top in Fig. 2, fit a circular
hole formed in the hub a', the side picces being fixed in position and acting as
guides for the bearings, t, t, when being adjusted to the shaft, n, by means of the
bolts at their backs and as the ends of said bolts are duly fitted into suitable holes
in the backs of the bearings they support said bearings vertically.
The bearings, u, u, are in every respect similar to the bearings, t, t.
The hard metal vessel a may be formed of more than one piece. The hard metal
pieces both of a and of d when worn may readily be removed and replaced by new
pieces.
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 I
claim is
1st. The arrangement of the piece d with the vessel a duly furnished with the
discharge hole in such manner that d may be operated on the bottom of and
within the vessel a as and for the purpose hereinbefore described.
2nd. The vessel a with the hole b, as, and for the purpose hereinbefore described.
3rd. The forms and arrangement of the bearings of the shaft n with their side
guiding pieces t', u', as, and for the purpose hereinbefore described.
Dated this 17th day of December 1891.
