| 摘要： | The Inland Waterways Corporation (IWC), the government-owned barge line, as mentioned last week, had built a fleet of vessels in 1920 intended for Warrior-Tombigbee River service. In 1929, they built yet another towboat for this area. The Charles Ward Engineering Works, Charleston, W.Va., secured the contract for what would turn out to be an unusual vessel. The IWC continued to move forward with experimentation in innovative technology, and this towboat would be no exception. The new boat was named in honor of the U.S. secretary of war, Dwight F. Davis, who would soon go on to an appointment as governor-general of the Philippines. A St. Louis native, Davis had been a tennis star in his youth and was the founder of what is now known as the Davis Cup international tennis competition. The Dwight F. Davis was similar in size to the Howard-built Warrior-Tombigbee boats of 1920, with a steel hull of 140 by 25 by 8 feet. Like the earlier boats, it was also steam-powered with triple-expansion condensing engines 10-1/4's, 16-1/2's, 27's with 18-inch stroke rated 1,000 hp. at 185 rpm. The twin propellers were 7 feet in diameter. The innovation and experimentation with this boat involved what fueled the water tube boilers. Boats built for the IWC were usually oil burners, but the Davis was set up to burn pulverized coal. A large shed-like structure midway of the boat evidently housed the mechanisms for this pulverized or "powdered" coal system. Two large ventilator scoops were positioned on top of the shed just forward of the twin stacks. In other aspects the Davis resembled a "modern" river tow-boat of the time. |
