No. 12169.—13th November, 1899.—WILLIAM HENRY CUTTEN, of Dunedin, New Zealand, Mining and Consulting Engineer. Improvements in buckets of elevators used upon gold-saving dredges.*

Extract from Specification.—The object of this invention is to provide an improved elevator-bucket for use upon dredges employed in obtaining gold from the beds of rivers, alluvial flats, and similar places. Hitherto difficulty has been experienced in elevating the tailings from the gold-saving tables, for immediately after it was scooped up by the buckets a great part or the whole would be washed out again by the water in the sump or by water from the tail chute of the revolving screen. I make the bucket with a false bottom, and in the pocket thus formed the fine material is scooped up from a sump. Behind the pocket I provide trays or second buckets, the backs of which form lids or covers for each succeeding bucket after they have passed around the bottom tumbler. The coarse material from the tail chute of the revolving screen is caught by the trays, but the water from this chute is prevented from washing out the fine material from the buckets by the backs of the trays. The false bottoms of the buckets have a steel lip, to stiffen them and lessen the wear. The backs of the trays may be made to slope forwards and fitted with a steel lip, so that they may dredge the fine material without the use of a false bottom.

Claim.—An improved elevator-bucket for use upon dredges employed in obtaining gold from the beds of rivers, alluvial flats, and similar places, substantially as described.

(2.) In combination, in the gripper of a cable dummy-car gripper, jaws, one of which (B¹) rises, the other falls away by being hinged (C) when the jaws are fully opened, and the jaw C, tilted up by the pin D, assumes its normal position during closing, with an automatic release-device F, F¹, F², for automatically opening the jaws by the action, substantially as described, and as illustrated in the drawing.
