(4.) An amalgamator, comprising an inclined amalgamating-
table, a series of wells below the surface of said table adapted
to contain amalgamating-material, two pairs of cylinders
journaled in said wells at right angles to each other and
obliquely to the flow of pulp, and two transverse cylinders
also revolving in said wells interposed between the pairs of
oblique cylinders. (5.) An amalgamator, comprising an
inclined amalgamating-table over which the ore-pulp is
adapted to flow, a well in said table adapted to contain
amalgamating-material, a pair of rotary cylinders journaled
in said well, said cylinders standing at right angles to each
other and obliquely to the flow of pulp, a portion of the
outer ends of said cylinders projecting beyond the side walls
of the table. (6.) Amalgamating-machines, comprising an
inclined amalgam-table, having a plurality of wells therein
adapted to contain amalgamating-material, two pairs of
diagonally arranged cylinders rotably mounted in each well,
and a pair of transverse cylinders for each well interposed
between said diagonal cylinders, means for discharging
water on to the table at intervals, and means for rotating said
cylinders. (7.) An amalgamator, comprising an inclined
amalgamating-table, a well in said table adapted to contain
amalgamating-material, a pair of tapered cylinders rotably
seated in said well obliquely to the flow of pulp, a pair of
transverse cylinders in said well below said diagonal
cylinders, said transverse cylinders having channeled peri-
pheries, and means for rotating said cylinders.

O’BRIEN, Storekeeper, both of Mitiamo, Victoria, Australia.
Improvements in means for moving goods.

Claims.—(1.) In devices of the class indicated, the com-
bination with a supporting frame of means for connecting it
to a platform, a truck movably connected to the frame, a
lever or levers for turning an axle or the like having frame
support, and connections as described between the axle and
truck, substantially as indicated. (2.) In devices of the class
indicated, the combination with a supporting frame of means
to connect it slidably to a platform, a laterally movable truck
connected to the frame, a lever or levers for turning an axle
or the like having frame support, and connection between the
axle and the truck to raise and lower the latter substantially
as indicated. (3.) In devices of the class indicated, having a
removable supporting frame, and a removable truck provided
with rollers, means for swinging the truck upward or down-
ward to any desired angle in combination with means for
sliding the truck laterally. (4.) In devices of the class indi-
cated, the combination of parts a to l described. (5.) In
devices of the class indicated, the combination of parts b to
h described. (6.) In devices of the class indicated, a wheeled
truck having means for attaching it removably to a frame or
platform, and to connections, and supports, and means
whereby to swing it upwards, the said truck when detached
being adapted for use as an ordinary goods-transporting
truck.

No. 19628.—26th June, 1905.—ALFRED EDWIN DAVIS, of
Cumberland House, 94, Pritchard Street, Von Brandis Square,
Johannesburg, Transvaal, Engineer. Improvements in filter-
presses.

Claims.—(1.) In filter-presses or apparatus of the nature
indicated, the combination with the receptacle fitted with
bottom discharge-door, filter-plates arranged and secured in
said receptacle in such a manner that the discharging of said
receptacle can be effected through the bottom without ne-
cessitating the removal of the filter-plates, said filter-plates
being so constructed that the solid matter deposited on their
surfaces is prevented adhering to the inside of the receptacle
round said plates, and means for passing through the filter-
ing media a fluid in the reverse direction to that of the
filtering flow, substantially as and for the purposes described.
(2.) In filter-presses or apparatus of the nature indicated,
