Big Dredge for Buffalo Breakwater Construction. - The dredge FIN MACCOOL, now nearing completion at Buffalo, is one of the biggest machines of its kind ever built in this country. It was built under the direction of H. T. Dunbar, with a special view to economical work on the Buffalo breakwater contract held by Hughes Bros. & Bangs. The dredge is of the clam-shell type carrying a bucket of 10 cubic yards capacity, which is adapted to digging in 100 feet of water. The bucket weighs fifteen tons empty. The hull has a bow of the vessel kind and is 150 feet over all, 40 feet beam and 12 ½ feet depth. There are two condensing engines (Wheeler surface condenser) each 18 ½ by 24 inches, supplied with steam from two Roberts water tube boilers of 150 horse power each. Cable is used in the dredging machinery and also in the handling of scows, for which purpose there are three drums on each side on deck. Instead of the spud ordinarily used in dredges, kedge anchors of the Baldt type are used for mooring purposes. There are five of these kedges, and the cables attached to them are led down to the bottom of the dredge by posts forward and aft, so that tugs and scows can be moved around the sides of the craft without interference. This big machine is designed to hoist 200 tons 30 feet a minute. The main hoisting gears are 12 feet pitch and chain 12 inches fall. Drums are 5 feet diameter, compound geared, 3 to 1 and 6 to 1, equaling 18 to 1.
