154 equipped with a patent releasing mechanism enabling the blocks to be quickly and easily released and re- placed under full load. The track is of tthe 4-way type resting on a foundation of yellow pine piling driven to refusal and ac- curately cut to gradient. The cradle runs on the track supported on free rollers which roll on heavy plates attached tto the track and the cradle with the spacing of the rollers and width of plates proportioned to be commensurate with the lifetime of the dock. The underwater portion of the track was built ashore, then launched and-carefully sunk into place between guides and fastened in place after a further check to assure align- ment. The cradle is drawn by six 2%-inch railway chains which are attached to. the cradle by a patented device which equalizes the pull of the several chains. These are operated by a powerful hoisting machine composed of a train of heavy spur gearing ac- tuated by an electric motor, alternat- ing current type, 250-horsepower, 440 volts, 3 phase, 25 cycles. The mia- chinery is equipped with an _ auto- matic and a hand brake for emer- gencies. It is arranged for two speeds depending on the load, being capable of lifting the full load on slow speed in 40 minutes. The general dimensions of this new dock are: Length on keel blocks, 360 feet; breadth, 70 feet; draft on keel blocks forward, 15 feet; draft on keel blocks ait, 20 feet.
