The first and two 15-in. piston valves, which are driven by Stephenson linkmotion. As the leading driving axle is cranked, the eccen-trics arc placed on the second axle, and the valves are drivenby long rods which are provided with knuckle joints and in-termediate bearings. The outside cylinders drive the secondpair of wheels. The four guides are braced by cast steelbearers, which are bolted to a single yoke extending acrossthe locomotive. The crank axle is built up with a cast steelcentral web. The main frames are of cast steel, 5 ins. wide, spaced between centers. The rear frames are of the same ma-terial; they measure 4 ins. in width, and are spliced to the. Balanced Compound Atlantic, S., P. & S. Ry. second rings in the barrel have diamond seams on the topcenter line, while the third ring, which carries the dome, hasa welded seam on top with a liner inside,. The firebox isbuilt with a straight back head and sloping throat, and isdouble riveted to the mud ring, which is of cast steel, 5 ins,wide all around. The throat sheet completely encircles thebarrel; it is flanged out of a single piece, and formed to fitthe top corners of the outside firebox shell. The back headis stayed with gusset-plates, which in turn are braced bylongitudinal stay rods, anchored on the boiler barrel. Thegusset plates are cut out to accommodate two rows of trans-verse tie rods, which support the flat surfaces of the outsidesheets above the crown. The smoke box is slightly ex-tended and is made in one piece. It is of the self-cleaningtype, fitted with perforated plates and a single high exhaustnozzle. , The cylinders are of th
