Improvements in Apparatus for Separating Coal or other Dust from
Water.
I, JOSEPH MOORE, of Ardgowan, Levenhall, Musselburgh, in the County_of
Mid Lothian, North Britain, Engineer, do hereby declare the nature of this In-
vention to be as follows, that is to say:-
This Invention has principally for its object the purifying of water from coal-
washing apparatus and which is charged with fine coal and other dust of greater
specific gravity, the improved apparatus is however applicable for other analogous
purposes.
The Invention consists in the application of a special arrangement of centri-
fugal apparatus hereinafter described. A horizontal shaft arranged to be driven
at a suitable speed, has fixed on it, within a cylindrical or other suitable casing,
a boss made with radial blades which occupy a large part of the breadth of the
casing. There is also formed or fixed on the boss near one side of the casing
a disk having radial ribs on its outer side. The inlet for the dust-charged water
is at the central part of the casing at the side where the ribbed disk is, the water
passing between the disk and the side of the casing to the other part. An outlet
for the more or less purified water is at the central part of the opposite side of
the casing, whilst the circumferential part of the casing is made with one or more
comparatively small tangential openings for the egress of the dust combined
with a small portion of water. By the action of the rotating blades the dust
which is of greater specific gravity than the water, is thrown towards the circum-
ferential part of the casing, whence being carried round by the motion, it passes
off through the tangential outlet or outlets. The inlet pipe is, preferably,
arranged so that the entering water may have some head; and the outlet pipe
for the purified water is extended up above the top of the casing so that the
casing remains full of water.

page_text: and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, that is to say:-
!
This Invention has principally for its object the purifying of water from coal-
washing apparatus and which is charged with fine coal and other dust of greater
specific gravity, the improved apparatus is however applicable for other analogous
purposes.
The Invention consists in the application of a special arrangement of centri-
fugal apparatus hereinafter described with the aid of an accompanying sheet of
explanatory drawings in which Figure, 1, is a longitudinal vertical section and
Figure, 2, a sectional end elevation:
A horizontal shaft, A, arranged to be driven at a suitable speed extends through
stuffing boxes; B; C, in a cylindrical casing, D. One end of this shaft, A; is
shown in Figure, 1, as being carried in a bearing bracket, E, attached to the
cylindrical casing, 1, and the shaft, A, has fixed on it, within the cylindrical
casing, a boss, I, made with radial blades, G, which occupy a large part of the
breadth of the casing, D). There is also formed (or it might be fixed) on the
boss, F; near one side of the casing, D, a disk, H, having radial ribs, J, on its
outer side. The dust-charged water is led to an inlet pipe, K, and enters the
casing, D, through an inlet, L, at the central part of the casing at the side
where the ribbed disk, H, is, the water passing between the disk and the side of
the casing to the other part. An outlet, M, for the more or less purified water is
at the central part of the opposite side of the casing, 1), which outlet communicates
with an outlet pipe, N, whilst the circumferential part of the casing is made with
one (or it might be more) comparatively small tangential opening, P, indicated
by dotted lines in Figure, 2, for the egress of the dust combined with a small
portion of water. By the action of the rotating blades, G, the dust which is of
greater specific gravity than the water, is thrown towards the circumferential
part of the casing, D, whence, being carried round by the motion, it passes off
through the tangential outlet, P, (or outlets). The inlet pipe, K, is, preferably,
arranged so that the entering water may have some head; and the outlet pipe, N,
for the purified water is extended up above the top of the casing, D, so that the
casing remains full of water.
The shaft (A) instead of being placed horizontally may be held vertically or
at any desired angle the other parts of the apparatus being arranged to suit and
the casing (D) instead of being cylindrical may be of other suitable shape.
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:-
Improved centrifugal apparatus for separating coal or other dust from water
comprising a shaft which has fixed on it, within a casing, a boss made with radial
blades and a ribbed disk, the casing having inlet and outlet openings at the central
part and one or more tangential openings, substantially as and for the purposes
hereinbefore described.
