22 MARINE REVIEW AND Koran ggg)» WAL PH PROGRESS OF WORK AT CRAIG'S a [Staff Correspondence. | Toledo,' O., Sept. 3--The prosperity which marks the ship yards of the great lakes finds its exemplification in the industry which is to be observed in the yards of the Craig Ship Building -Co., Toledo. It is an industry which is not confined to ship construction alone, but which expends itself also in an extension of the plant. During the past year the plant itself has practi- cally doubled'in its capacity to produce. A review of the work on hand shows that the company has just launched the tank steamship Toledo for the Sun Co. of Pittsburg, of which Mr. J. M. Pew of that city is president. This tanker is 263 ft. long, 43 ft. beam and 25 ft. deep, with a carrying capacity of 900,000 gal- lons of oil. She has a triple-expansion engine with cylinders . of 21, 35 and 58 in, diameter and a stroke of 4o in. Steam is supplied by two Scotch boilers, 14 ft. 3 in. in diameter and 12 ft. long; each fitted with three corrugated furnaces, supplied by the Lake Erie Boiler Works, Buffalo, N. Y. - The vessel is divided into' eight cargo tanks, separated from the rest of ship by cofferdams 'and continually kept full of water. The oil is isolated from the balance of the ship both forward and aft. Aft of the oil cargo space the machinery is placed, together with galley and quarters for engineers' crew. Forward of the oil cargo space is a pumping station supplied with two large MARINE RECORD.

She is built on age Vaal ate system which gives g-ft. hatches in place of the 8-ft. hatch generally used in this class of steamers. Her hold is divided into five cargo compartments 10. order to permit her to carry mixed cargoes of grain. She will have no hull beams and to compensate for the strength in construction lost thereby she will be fitted with webb frames. Her cargo bulk- heads too will also make up for strength Jost in the omission of beams. This form of construction 1s intended to facilitate the problem of unloading and is expected to lend itself readily to the automatic unloading machine. There will be two hatches to each bulkhead and no beams to interfere with the grabs of the unloading buckets. Her engines will be triple-expansion, 21, 35 and 58 in. in diameter with stroke of 40 in., supplied by steam from three Scotch boilers, 11% ft. in diameter and 12 ft. long, allowed 180 Ibs. pressure. The company has just secured a contract to build a car ferry for the Grand Trunk Ferrv Co of, Milwaukee. -- Mr. Crosby of the Crosby Transportation Co. is president of this company and controls it, though it is entirely independent of the Crosby Transportation Co. The ferry will be 315 ft. long, 52 ft. beam and 38 ft. deep, and will carry twenty-six cars on four tracks and have accommodation for 1,000 passengers. She will be fitted with twin-screws, each screw being operated by a triple-expansion engine of sufficient size to drive the steamer 15 Sectional views of the tank steamer Toledo, nearing completion, at the yards of the Craig Ship Building Cao., Toledo. duplex pumps for handling oil cargo. 'These pumps were fur- nished by the Snow Co. of Buffalo. The sailors' quarters are on the forecastle deck at the forward end of the vessel. The captain's and officers' quarters, as well as the pilot house, are located in the center cf the ship. This structure is supported on stanchions in the center and by the hull of the ship at the sides, leaving an air space between the bottom of the structure and the deck of the boat. The Toledo is equipped as an oil burner. An air blast will be used for a spray, the oil being fed by a small air compressor. She is intended to run between Marcus Hook and the.'Texas oil fields. She has just been launched and will leave for the coast about Oct. 1. The construction of the ves- sel was supervised by Mr. Edward Gaskin of Buffalo,, who de- signed her for the owners. The Sun Co. is in the business of piping, tanking and transporting oil. It has a sufficient supply already tanked in Texas to keep its vessels in operation for two years. The Toledo is No. 90 on the builder's list and will cost approximately $225,000. _ A cargo steamer is also under construction (builder's num- ber 91) for the Monroe Transportation Co. of Detroit, which will be, in a measure, a duplicate of the steamer Thomas Adams, recently turned out from these works. Her dimensions are: Length over all, 285 ft.; beam, 50 ft.; depth, molded. 28 ft. It is expected that she will be launched in January next and miles an hour. Steam will be supplied by eight Scotch boilers, I1xtt ft.. each boiler being fitted with two Morison corrugated furnaces. It is intended to use only six of the boilers in sum- mer and the entire battery in winter. She will run from Mil- waukee to Grand Haven and will crush whatever ice may form by sheer force of weight, her stem being so constructed as to permit her to run up upon it. She will have power sufficient to go through ice a foot thick at the rate of 8 miles an hour. She is to be delivered next July and will cost approximately $350,000. The company also has a contract for a full-sized canal steamer, fitted entirely for salt water purposes, but constructed like the ordinary type of lake steamers with engines aft. The company is also to build another oil tanker, practically a dupli- cate of the Toledo, but further particulars regarding. these two vessels are not at present obtainable. The yards of the Craig Ship Building Co. to-day bear no relationship to what they were a year ago. During that time a 75-ft. addition has been made to the machine shop, and a num- ber of new tools installed. A 60-ft. addition has been made to the foundry and an extra traveling crane added. The entire yard is now operated with electricity from one power station, doing away with all steam engines. 'The generators and motors were supplied by the General Electric Co. A large pair of
