LIKE THE THREE-CYLINDERS

Latest Idea in Locomotives Is Announced by Experts to Be Pronounced Success. At the last annual convention of the American Railway Master Mechanics’ association Mr. J. S. Bell read a paper on the subject of three-cylinder locomotives, in which he gave particulars regarding three of this type which have been giving good service. The three cylinders are placed on the same horizontal plane, one between the frame and other two exterior to the frame. They have the spme diameter, 18% inches, and each has its Own piston valve. They have been engaged for several years in fast passenger service, where they have been doing very satisfactory work. Their principal advantages are that they' secure a uniform turning moment, the cranks being placed at 120 degrees; they exert greater tractive power, and they call for a lower factor of adhesion than two-cylinder engines. They are easy on rails and bridges; afford opportunity for better balancinng, and can be operated on the simple, compound, or triple-expansion principle.—Scientific American.
