FAST EXCURSION STEAMER CHIPPEWA.
One of the neatest and fastest of the small passenger steamers on the great lakes is the CHIPPEWA which has just finished her first season on the route between Cheboygan, Mackinaw island and Sault Ste. Marie, Mich. through the picturesque Sault river. The CHIPPEWA, owned by the
Arnold Transportation Co. of Mackinaw, Mich., is easily an 18-mile-an-hour boat. She was guaranteed by her builders, the Craig Ship Building Co. of Toledo, O. to maintain that speed for five hours and has more than equaled expectations of both owners and builders. The Craig company has reason to feel proud of this vessel, as she has been an object of special interest throughout the season, not only to the high class of tourists who patronize the Mackinaw and Sault river districts. but also to vessel men and ship builders who know how to appreciate a well-designed passenger vessel.
The CHIPPEWA is 206 ft. over all, 34 ft. beam, 21 ft. 6 in. molded depth and 8 ft. 6 in. between deck She is of mild steel throughout. including the main deck; was built to comply with the requirements of the Bureau Veritas, and was inspected during construction and classed by Capt. Herriman, surveyor general for that register. The steamer is built on what is known as the bar-keel system, the center keelson forming the keel, with garboard plates flanged to the same. The center keelson is 32 in. by 15 lbs. from stem to stern-post, center keelson plate 18 in. by 15 lbs., connected to center keelson by 3 x 3 in. x 6 lb. angles. Floors of frame are made of 12 ½ lb. plate, except under engine and 'boilers, where the plates are 16 lbs., all connected to center keelson by double 3 ½ x 3 l/2 in by 6 lb. angles. The steamer's frame is 3 x 5 in. by 12 lb. angles, 24 in. to centers; reverse frame is 3 x 3 in. by 6 lb. angles. There are three stringers in the main hold, equally distant from keel to main deck beams, these stringers being composed of two 3 x 4 in. by 8 lb. angles to each stringer. Between these angles to each stringer is a 10 lb. intercostal plate, between the frames, and connected to shell plating by intercostal plates, being flanged against the shell plating, thus making the side of the structure very rigid. The main deck beams are of 8 in. channels. connected to frame by 12 ½ lb. gusset plates. Main deck stringer is 30 in. by 16 lb. plate; main deck 10 lb. plate, upper deck beams 3 x 5 in. angles, spaced to 48 in. centers, and upper deck of wood, covered with canvas. The garboard plate is 17 ½ lb., the sheer strakes 17 ½ lb., and the balance of plating from main sheer strake to garboard 16 lb., so as to make the steamer look smooth. All the butts were strapped inside - not lapped, as is the common practice. The plating from main deck to upper deck is of 10 lb. plate. The stem and stern-post are of wrought-iron, forged.
Propelling machinery consists of a triple expansion engine, with cylinders of 20, 32 ½ and 55 in. by 30 in stroke, also designed and built by the Craig company. The cylinders are covered with asbestos, 3 in, thick, and lagged with 1/8 in. steel. The high pressure and intermediate cylinders have piston valves and the low pressure cylinder has slide valves, all actuated by Stevenson's link motion. Each valve has its own cut-off, actuated by screw in the arm of reversing shaft. All valves are operated by steam reversing gear. All journals, except crosshead journals, are made with steel sleeves, and filled with Merchant & Co.'s genuine hard babbitt. Cross-head pins have brass journals, the main shafting being of iron, forged, with couplings forged on. The driving shafts also have driving collars forged solid onto shaft; driving bearing of the horseshoe type, all 11 in. in diameter. Crank pins are 14 in. long in the bearing, 11 in, in diameter, and are made of acid open-hearth steel. The propeller wheel is 10 ft. in diameter and 16 ft. lead, The air pump is of the vertical compound type with steam cylinders 10 and 18 in. x 16 in. The feed pumps and bilge pumps are of the admiralty type. With the engine making 135 to 140 revolutions, a vacuum of 25 in. was maintained, with the air pump making 28 strokes per minute, giving the very best of satisfaction, This engine was made to work to a maximum capacity of 150 revolutions per minute, with 225 lbs. boiler pressure,
The CHIPPEWA has four boilers of the Roberts type, built by the Roberts Safety Water Tube Boiler Co. of 39-41 Cortlandt street, New York They are set in pairs, each pair having its own smokestack. Two are forward of the boiler room arid two aft. '['hey are each 9 ft. long by 9 ft. wide Their collective grate surface is 212 sq. ft.; collective heating surface about 6,700 sq. ft. The engines developed over 1,000 H. P. with only two of the boilers in use. The weight of the four boilers including contained water at steaming level. and everything except smokestacks and breechings is about 41 ½ tons.
The main cabin is situated on the spar deck. It is of mahogany throughout and contains twenty-four staterooms. The captain's, mate's and quartermaster's rooms are on the hurricane deck, as is also the large smoking room just forward of smokestack. The dining room is on the main deck, aft of after gangway, and connected to the main cabin by a social hall on the main deck opening to stairway to cabin above. The social hall and stairway are finished in mahogany, similar to the cabin above. The dining room, aft of social hall, is finished in China white and gold, and will accommodate eighty people at one sitting, The galley and crews' quarters are directly under dining room. The steamer is thoroughly ventilated with McCreary's ventilating system. She is lighted by 225 16-candle-power lights, and has also signal lights, as well as a 5,000 candle-power search light on top of pilot-house for running the for running the "Soo" river by night. Steering gear is of the Williamson Bros. make - combination hand and steam.
