As each in- dividual rope was cut it was indicated at the switchboard. The difference in time of the cutting of the six ropes forward and aft was practically nil. To give one an idea of the time consumed, it can safely be stated that three seconds after Mr. Mayo, of the Ford Motor Co., closed the launching switch, the ship was on its way to join the many other ships of the Great Lakes. Steering Engine The steering engine is of the direct- acting electric type, direct-connected by cast steel quadrant with pinion on the engine. The teeth of the quadrant are made in segments so they can readily be removed or renewed. The steering en- gine is of the American Shipbuilding Co. make, with the Benson Electric Co. con- trol. It is operated by two 50-horsepower Westinghouse motors that run at 475 revolutions per minute. Either motor can be thrown in or out of gear from the pilot house by an electrically oper- ated clutch lever at the engine, so in case of accident to the port side of the mechanism ,the starboard side can be thrown in instantly. The gears, ex- cept the motor pinion which is fabroil, TTT TT. fa 308" em PRameg Z PEE Foal) recon EEE Le ant bitawecrs am mene.

The engine is mounted on a sliding bed so that by screw ad- justment it can be brought in contact with teeth on the quadrant to proper pitch line. The operation of the engine from the pilot house is all electric, using the Benson Electric steer-motor, which steers with the greatest ease. This wheel stand is also in duplicate, controling either port or starboard gear at engine. A hand stand aft on the upper deck can be used in emergency. This is of the American Shipbuilding Co. make and is operated by two brass wheels 63 inches in diameter. The windlass is the standard American Shipbuilding Co. electric type. All gears are steel castings with machine cut teeth. The wildcat and releasing gear is easily operated and very accessible. Wildcats are designed for 2%-inch cast steel stud link chain. The windlass is driven by a 50-horsepower Crocker Wiheeler motor at 850 revolutions per minute. Six automatic tension electric moor- ing winches, designed and built by the Lidgerwood Mfg. Co., New York, are installed on this vessel, four on the spar deck between hatches, one aft in the fan tail and one forward in the wind- lass room. ‘These six winches are all duplicates except that a winchhead is provided on the stern winch for aux- iliary steering purposes. The winches have been designed to accomplish elec- trically all of the work previously done by the steam mooring winches, so long familiar to operators of lake vessels, and in addition present some advantages not found in the steam winches. Electric Winches ‘The winches are single worm gear drive from the drum is designed to hold 70 fathoms of 1% inches diameter wire hawser, and is bushed to the shaft but ‘secured thereto by a heavy square jaw clutch. A wheel and screw set band brake is drum, with motor. The mounted on the drum flange, -and bar - holes and ratchet and pawl are also provided for hand operation when no power is available. The winch is de- signed for maximum pull onthe mooring hawser of 14,000 pounds and can be controlled for hauling speeds under full load of from 25 to 50 feet per minute at the discretion of the op- erator, and will either pay out or wind in the light hawser at speeds in excess of 100 feet per minute. The parts of the winches are all designed to with-
