No. 11746.-26th June, 1899.-HERBERT PARK, of Sydney,
New South Wales, Civil Engineer. Improvements in gold-
dredges.

Claims.-(1.) In gold-dredges, first separating the larger
particles of the dredged material from the smaller, passing
the smaller particles into a hopper or special receptacle to
receive them, separating the bulk of the water from the
smaller particles, and then elevating the smaller material in
order to reunite it to the previously separated larger material,
as set forth. (2.) In gold-dredges, first separating the larger
particles of the dredged material from the smaller; then
passing the smaller particles over suitable tables for the
purpose of separating the auriferous materials mixed with
them, while the residuum, or tailings, will fall into a hopper
or special receptacle to receive them, separating the bulk of
the water from the smaller particles, and then elevating such
tailings in order to reunite them with the previously separated
larger material, as specified. (3.) In gold-dredges, a suit-
able screen or screens and a suitable concentrating table or
tables, in combination with a hopper to receive the tailings
and an elevator to raise the tailings and reunite and stack

them with the previously separated grosser particles, as set
forth. (4.) The general arrangement, construction, and
combination of parts in the improvements in gold-dredges,
as described, and for the purposes set forth.

usual boxes of smaller side-boxes, such as a, having perfora-
tions for guiding the stuff on to the tables, with tables and
