Malauce-cylinders are fitted to the valves of all tlireecylinders, to reduce the strain on the valve-gear as far as possible. The valve-gear is of tliedouble-eccentric, link-motion type, all joints having exceptionally large surfaces. A double-cylinder reversing-eiigine is provided, and tiie reversing shaft-levers are fitted with screw-gearto allow of the expansion in each cylinder being altered independently of tlie others. Theback columns are of cast steel, with .-separate pinned-oii faces for the guides, and the front ENGINES, MARINE, 277. 278 EXGIXES, MAKIXE.
