Telescope 23 "Lansdowne of Windsor" by Gordon P. Bugbee PART TWO (CONCLUDED) While the LANSDOWNE is conspicuous chiefly for her paddle wheel propulsion, her engines differ significantly from those of sidewheelers we were accustomed to seeing until recent years. The demands of a cleared main deck for railroad cars have limited the engines of railroad carferries. The HURON represents the modern carferry in having her engines wholly below the main deck and driving twin propellor shafts, while her main deck is almost completely clear of cabins. But the IANSDOWNE takes advantage of the broad lateral overhang of a sidewheeler, her two engines occupying separate engine rooms on the main deck forward of the paddle boxes and flanking the railroad car tracks. 'The ancient engines inherited from the MICHIGAN are horizontal direct-connecting engines originally built at Montreal by Gilbert & Sons in 1872. Each engine has a single cylinder of 48" diameter and 108" stroke, operated at 65 pounds of steam pressure to provide a top speed of fourteen miles per hour. The low pressure and slow movement of the engine parts are responsible for their long life, as we have already observed. Each engine drives a paddle wheel of 29'-5" diameter having twenty-two buckets and weighing thirty tons. These are "radial" wheels with fixed buckets, as distinguished from the "feathering" wheels just coming into wide use in 1884. Feathering wheels had buckets pivoted at their ends and guided by an eccentric arm so as to remain nearly vertical while passing through the water. The feathering wheels could be nearly half the diameter of the radial wheels doing the same job, and accordingly they were much lighta:. And feathering wheels which were the size of the IANSDOWNE radial wheels drove the 536-foot GREATER DETROIT, the largest vessel ever built to be propelled exclusively by paddle wheels. But the radial wheels are probably sturdier than feathering wheels, especially for ice conditions. With her bow also reinforced for ice breaking, the IANSDOWNE is active during the stormy winter months. Unlike most sidewheelers, each paddle wheel may be driven
