Thecenter of the valve rod is j^ inches aboveupper rocker pin, for the purpose of giv-ing lateral clearance between the rod andthe front driving ti-e. The rod has aknuckle joint and is dropped again at itsjunction with the stem. The steam portsare i8 x If^ inches, and the exhaust portis 50 X 9 inches. The bridge is 6ii incheswide. The valves have 1% inches outsidelap and 14 inch inside clearance, with6/2 inches maximum travel. To control the tremendous force trans-mitted from the cylinders of these en-gines the main frame is forged solid 5inches wide and 5 inches deep at the jawsand 4 i
