In some of the older joints, the outside bars extended along the side of the railhead, but this practice has been abandoned. The bars should he so designedand proportioned as to make the joint as strong and stiff as the body of the rail,but many joints are defective in stiffness to resist slight deflections. The barsare usually of uniform section thi-oughout, but sometimes have the thickness ofthe web increased at the middle by tapering from the ends or by flange sometimes extends only about i-in. beyond the rail base, or barelycno-~i tl g-ve a hold for the slot spikes, as in B, Fig. 42; in such case, Section!? of Splice Bars. spikes may be crowded out of position by a creeping track. It is better to havewide flanges with deep slots for the sfjikes, and some roads have them wideenough for spike holes instead of slots, the spikes then resisting motion in everydirection and the gage being more permanentlj maintained. The base of theflange is usually brought down level with the bottom of the rail, so as to take abearing on the tie, as in Figs. 30, 35 and 42. Many roads, however, keep theflange clear of the tie, as in Fig. 42, C. The sections of .splice bars vary verygreatly, as shown in the illustrations, but one of the best is the Sayre section,shown in Fig. 30. The heavj^ top chord makes an exceptionally stiff bar, withwide bearing surface for the rail head.
