Their hands struck blood from the helmets. Right grim was the clash of swords! Many a shield-plate sprang in sunder, and the precious stones were scattered among the blood. So fiercely none will fight again. The prince of Bechlaren hewed a path right and left, as one acquainted with battle. Well did Rudeger approve him that day a bold and blameless knight.
Bold Siegfried and King Ludger strove together, and lances whizzed, and sharp spears. Ludger's shield-plate flew off through the strength of Siegfried's hand. Then the hero of the Netherland thought to have gotten the victory over the Saxons that were hard pressed. Ha! what polished bucklers doughty Dankwart brake!
The plates should then be rocked up and down by hand and the friction at different points noted. The horizontal rod at the back of the valve-gear may be loosened and the amount of end play of each individual shield-plate noticed and compared with the bushings on the horizontal rod at the back which binds the shield-plates together.
They are free fits on the pins which pass through the heads, and no friction is likely to occur which will interfere with the regulation, but too close work on the shield-plate bushings, or a slight warping of the steam chest, will often produce friction which will seriously impair the regulation.
These plates are set, one a little ahead of the other, to obtain successive opening or closing of the valves. When more steam is required the shield plate allows the proper pawl to fall into its notch in the cross-head and lift the valve from its seat. If less steam is wanted the shield-plate rises and allows the lower pawl to close the valve on the down stroke.
If it is noticed that the shield-plate shaft has any tendency to oscillate in unison with the rock-shaft which carries the pawls, it is a sure indication that the shield-plates are not as free as they should be, and should be attended to. The governor-rod should be disconnected, the pawls thrown out and the pawl strings hooked over the ends.
