DETAILS OP VALVE GE.\R OF TEN-WHEELED PASSENGER LOCOMOTIVE, BY THE ROGERS LOCOMOTIVE COMrANT. TEN WHEELED PASSENGER LOCOMOTIVE. The full page engraving herewith represents one of thelocomotives eviiibiled by the Rogers Locomolive Company atthe Chicago Exhibition. It is an excellent example of a Ijpeof heavy passenger engines which of late .years have beenadopted on lines on which train loads have grown beyond thecapacity of eight-wheeled engines. The fire-box is inlended for burning bituminous coal, andis placed on top of the frames, the crown-sheet being stayedwith radial stays. The springs are underhung. On a 10-wheeleil engine of this kinil there is always more orless dilficulty in connecting the links with the has been overcome by a very neat design of the variousparts of the valve-gear. Separate engravings of these ]iartsare given which show very clearly how are 1
