as MARINE REVIEW AND: MARINE * RECORD. a= = : a AT THE JENKS SHIP BUILDING CO.'S YARDS A spirit of energy pervades the yards of the Jenks Ship Building Co. at Port Huron; Mich. The company has just de- livered the wrecker Thomas F. Newman to the Great Lakes Towing Co. and believes it to be the most thorough-going vessel of its kind on the great lakes. It has under way a duplicate of the Henry Steinbrenner for the Cowle Transportation Co. of which Capt. W. W. Brown of Cleveland will be the manager. She will be known as the John B. Cowle and it is expected that she will go into commission this fall. Her dimensions are: Length over all, 440 ft.; keel, 420 ft.; beam, 50 ft.; depth, 28 ft. 'She will have a triple-expansion engine with cylinders 23, 38, 63 jn. in diameter with stroke of 40 in. Steam will be supplied from three Scotch boilers 12% ft. wide andi2 ft. long. As she differs in no way from the prevailing type of vessel she merits no further 'description. 'The company is also building the hull of a new fireboat for the city of Detroit of the following dimensions: Length over all, 122 ft.; beam, 25 ft.; depth, 13 ft. The engines 'of the old fireboat Detroiter will be installed in the new tug. 'The new fireboat will be a very staunch vessel indeed. Her keel 'and stem>is to be of wrought iron, 5 in. by 1% in., properly 'scarfed together and grooved to take the lower edge of inter- ccostals. 'The stern post is to be of cast steel, properly scarfed to keel. The rudder frame is to be solid forged, stock 5% in., pintle 3Y in., plates 11 in. The main frame is to be constructed of angle, '4 in. by 4 in. by 98 lbs., spaced 15 in. apart forward of No. 17 'and 20 in. for the remainder. The bulkhead frames are to be double 3 in. by 3 in. by 8 Ibs. ~The reverse frames are to be angles 2% in. by 2% in. bv 5 lbs. The engine, fire pump bearers and thrust bearing are to be of steel plates and angles. Suitable tearers are also to be provided for feed pumps, electric genera- tor and all other machines. The deck and pilot house is to be of 'steel. The skylight over the engine and boiler room is to be of 'steel angles and plates, gratings of white ash to be fitted on top 'of pilot house and aft end of deck house. ©The tug is to have a 'gypsy steam capstan. It is to be lighted throughout by elec- tricity for which the General Electric Co. will furnish the engines and: generators. A monitor made by the Fabric Fire Hose Co., "No. 88 Murray street, New York. is to be connected with the fire pumps. The tug is to be completed by Dec. 15. apr "By the'end of the present month the company will deliver to 'Maj. J. G. Warren, lighthouse engineer at Milwaukee, the light- house tender Hyacinth. She is 160 ft. long, 28 ft. beam and 14 ft. deep_and is equipped with a fore and aft compound engine, 22 and '2 by 36:in. Steam will be supplied by two boilers 11:6 'ft. in diameter and 11 ft. long. Her machinery is in and she is practically complete with the exception of the cabins. -... The lighter, Thonvas F. Newman, recently completed is a Single. decked steel vessel with topgallant forecastle for the ac- eommodation of the crew and boiler room. The pilot house is ontop of the forecastle: 'The after end of the deck is raised level to the rail, forming a half poop in. which provision is made for stowing pumps.- She has_no propelling engines, being built solely in that respect with a view to being towed. Her general dimen- sions, are: Length over all, 173 ft.: length between perpendicu- Jars, 165 ft.; beam molded. 26 ft.; depth, 15 ft. 'The lighter is built staunchly throughout. 'lhe stem is of the best hammered scrap iron forged in one piece, 7 in. wide and 134 in. thick. It overlaps the keel plate 8 ft. The rudder is of the balanced type. The floors are of channels 15.in. by 33lbs. per foot and flanged to conform to the shape of the vessel. The side frames are of chan- nels 6 in. by 3% in. by 15 Ibs. per foot for three-fourths length amidships beyond which they are reduced to 13 Ibs. per foot. They are spaced 24 in. apart except forward of collision bulk- head where they are closed in to 18 in. spacing. The center keelson is formed of a 14 lb. intercostal plate flanged to keel plate and connected to floors with double 3 in. by 3 in. by 7.2 Ib. angle clips. The sister keelson consists of a 12.5-lb. intercostal plate, flanged to shell and clipped to floor with single 3-in. by 3-in. by 7.2 Ib. angles. The keel plate is 48 in. wide by 20 Ibs. per square foot, tapering at after end to 17% Ibs. per square foot. 'The main hatchway extends from forecastle bulkhead to poop bulkhead aft and is framed along each side with a 15 in. by 33 'Ibs. per foot channel, standing 6 in. above deck where it is doubled with a reverse channel 6 in. by 3% in. by 15 Ibs. per foot which is riveted on top of deck plating. At intervals of 8 ft. a. 15 in, by 33 lb. channel is fitted throughout the hatchway, ex- tending the full width of the hatch and connected to the channel fore and aft on each side by double clips of 4 in. by 4 in. by 98 Ibs. aneles and by. 15 in. bracket plates on under side. The deck beams are of 9:in. by 20 lb. channels spaced on every second [Sept. Il, Ta WB? abe - eine << NWI | = O WS" AS me and abreast of hatchway are connected to hatch fore and iG double clips of 4.in. by 4 in. by 9.8 lb. angles, and to heads of frames by flanged bracket plates, 14 lbs. per square foot, Watertight bulkheads are fitted both forward and aft, of the cargo hold and a division bulkhead in the center. As previously stated the boiler room is in. the forecastle. The boiler is of the Scotch type, 5 ft. in diameter by 8 ft. long, fitted with one plain circular furnace and Shelby steel tubes. 3 in. in diameter, A Pemberthy automatic-injector is fitted for feeding the boiler. A No. 3 vertical duplex air pump, made by the New York. Air Brake Co., is also fitted in the firehold bulkhead. The lighter was designed by Mr. Robert Logan of Cleveland and with the McMyler hoist, the donkey engines, air compressors and pumps is a most serviceable vessel. She has already been called the marine ambulance of the lakes and is well fitted with her equipment to lighter cargoes and assist disabled or stranded vessels. COLUMBIA IRON WORKS, ST. CLAIR, MICH. Great progress is being made upon the construction of the plant of the Columbia Iron Works at St. Clair, Mich., and in a few months it will be in complete operation. The ship yard has a frontage of 1,800 ft. on the St. Clair river and embraces alto- gether about fifty acres. The company's initial contract is for the construction of a small cargo steamer for Chicago and Buffalo parties. The steamer's dimensions will be as follows: Length over, 215 ft.; keel, 200 ft.; beam, 39 ft.; depth, 16 ft. Her engine will be triple-expansion with cylinders 16, 26, 44 in. in diameter, with 36 in. stroke. Steam will be supplied by two 'Scotch boilers 12 ft. in diameter and 10.6 ft. long. Her hatches will be 12 ft. fore and aft and her beams will, therefore, be extra heavy to compensate for the added length of the hatch. The pur- _ pose of this departure in hatch construction is to facilitate un- loading. She will cost approximately $100,000. Preliminary work has already been begun upon her though the company has 'had some difficulty in obtaining material. The company is also negotiating for the construction cf three other vessels but the negotiations are not sufficiently advanced to warrant a more par- ticular announcement. A while back a suggestion was 'made to the company of the advisability of constructing a cargo carrier. with. a hopper . bottom which was held fo have .certain. advantages, especially as a grain car- 'rier, over the ordinary type of vessel. Prof. Durand 'the consulting engineer, gave the subject. considerable thought and after weighing its advantages and disadvantages decided that tts advantages were not sufficiently definite to compensate for the extra cost that such form of construction would avail over tlie old type. The company, therefore, decided not to undertake the experiment. ; Everything, as might be expected, is trim about the yard. The buildings are the best that could be constructed for their 'various uses as far as convenience goes and their equipment throughout is of the latest and most modern design. The punch shop is 260 ft. long and 65 ft. wide. 'The second floor is carriéd upon steel trusses and is utilized as a: mold loft, 200 ft. long and 65 ft. wide. A drawing office, 20 ft. long and 65 ft. wide is also upon this floor. The furnace and forge building is one story in height and is 150 ft. long and 50 ft. wide. 'The machine shop is 180 ft. long and 65 ft. wide with a gallery on one side, and an erecting wing 40 by 35 ft. The foundry is 96 by 65 ft. and is equipped with two cupolas, one of 7 tons capacity and the other of 2 tons. The power house is of brick 37 by 75 ft. The wood- working shop is a two-story building, 30 by 7§ ft. ~Another building is devoted to the office and store room and is very com- modious. 'The building berth, extending along the water front, 1s capable of accommodating three vessels at one time. All the buildings are so related to the ways as to diminish the handling of materials employed in the construction of the vessels to a minimum. 'The yards are thoroughly interlaced with railway tracks so that each building has a complete railway service. The company's equipment of machine tools is superb and among the manufacturers whe contributed. are the following; Hilles & Jones Co., Wilmington, Del.; Cleveland Punch & Shear Works, Cleveland; Reade Machinery Co., Cleveland; Acme Machinery Co., Cleveland; Betts Machine Co., Wilmington, Del.; Detrick & Harvey Co., Baltimore, Md.; Davis Machine Co., Rochester, N. Y.; Bickford Drill Co., Cincinnati, O.; Buffalo Forge Co. Buffalo, N. Y. The officers of the Columbia Iron Works are: J. E. Botsford, president; C. O. Duncan, vice president; F Jenks, secretary and treasurer; Prof. W. F. Durand, consulting engineer. pe
