No. 12580.—3rd May, 1900.—GEORGE WILLIAM GOUGH, Architect, and ROBERT ANDREW, Mining Agent, both of Dunedin, New Zealand. Improvements in suction dredging and bucket dredging.

Description.—The invention comprises the following parts: viz., a centrifugal or suction pump placed in centre or between sides of ladder; suction-pipe; non-return valve; inlets at end of ladder joined together by junctions on to suction pipe at non-return valve; bars of iron forming grid or grating at mouth of inlets; delivery-pipes from pump branching on each side of ladder. The pump is driven by belt on a pulley from convenient intermediate shaft, or may be driven by electric motor. The mode of operation is that the loose material falling from the buckets or lying on bottom is sucked in at inlets, passing up suction-pipe, thence through pump, and discharged through discharge-pipes either right or left hand on to convenient shoots communicating with screen or gold-saving tables. The whole of the apparatus is placed inside the construction of the bucket-ladder, except the driving-pulley.

Claim.—The combination of the various parts as a whole for suction dredging. The inlets B2, as constructed and shown at lower end of bucket-ladder.
