The crossheads havesteel bodies with bronze gibs 32 in. in length and are verysimple in design. They weigh 785 lb. apiece, and althoughlarge in itself, this weight may be considered low for thesize required. The front and back main rod stubs are of theMarkel type with removable brasses. .\s shown in one of thedrawings, the cast steel filling blocks in the main stub arecored out to remove as much weight as 263, Z^Tubes ^F/ues24oLong. 108% Cross-sectional Elevations of the Boiler Talmage ash-pan and blowofi system, Franklin grate shakerand firedoor and Chambers throttle valve. The cylinder castings are simple and massive in design, andare secured to the frames by 12 horizontal lj4-in. bolts the cylinders and steam chests are fitted with bushingsof gun iron and the same material is used forpiston and valve packing rings. In designing the cylinders • hving to the comparatively large diameter of the wheelsand the relatively light reciprocating weights it has beenpossible to balance the locomotive very satisfactorily. It wasunnecessary to resort to the use of auxiliary counterweightson the main axle, and lead has been used in the counterweights of the main wheels only.
