This includes, in the brass foundry, one 2-ton crane; copper and brass shop, one 1-ton crane; machine shop, one 15-ton crane, and pipe shop, one 1-ton crane. The sheet metal shop is located in the extreme end of the south leg of the S. This shop is fully equipped with breaks, punches, gate shear, drill presses, etc., to do any kind of work on plain and galvanized sheet metal. The second floor of this building is divided about half and half between the joiner shop and the pattern shop. Outside machinists are equipped for and capable of taking care of any kind of repair work on diesel or reciprocat- ing engines, turbines, wheel jobs. Ample rigger facilities are provided. One of the important adjuncts to repair facilities of this plant is the repair barge which is the _ largest floating ship repair shop in the Port of Baltimore. It contains a _ black- smith forge, drill press, lathe, shaper, two pipe cutting and threading ma- chines, emery wheel, two generators and two air compressors. The docking facilities available for taking care of vessels that come in for repair work and overhauling are as follows: 1—A graving dock, large enough to take care of vessels having a length of 580 feet, beam 60 feet and draft 22% feet. This is located between piers No. 1 and 2 and is served by tower crane, having a maximum lift- ing capacity at long boom of 15 tons. The pump house for this dock is located on pier 2 and the dock can be emptied in 90 minutes. 2—A 6000-ton floating dry dock having a mean low water depth of 37 feet. This is located between piers No. 4 and 5 and is served by a 15- ton (long boom capacity) tower crane, located on pier No. 5. The completion of the Baltimore Dry Docks works gives Bethlehem three unusually well equipped plants on the East Coast. The other two are (a) the Boston plant, consisting of the former Atlantic works and the Simpson Dry Dock plant, located in East Boston, Mass., which have been thoroughly modernized in much the same way as the Baltimore Dry Docks works, and (b) the Fore River plant. On the Pacific Coast the Union plant, includes the Portrero works, Hunter’s Point works and Alameda works in San Francisco harbor. The San Pedro works in Los Angeles har- bor, is equally well equipped to handle any and all classes of ship repair work, as well as new construction.
