Marine Review (Cleveland, OH), 13 Jul 1899

Manager D. E. Ford of the Superior Ship Building Co. is enthusiastic over a valve gear that was built at the West Superior works some time ago and placed on the engine of the ship building company's tug Islay. The gear is the invention of Lincoln A. Lang of Yule, North Dakota. Mr. Ford says of it: "The gear we placed on the Islay has been running without repair or re-adjustment since we started it last July. On the fuel trial, which we gave this gear against the Stevenson link gear, the engine was worked up close to maximum power, and the saving in fuel through using the new gear was clearly 20 per cent., with conditions alike on both trials. With the new gear the saving in fuel is much greater than this, with the engine working at lower powers. The engine works with a more even turning motion, with less vibration, and is much easier kept up than formerly."
