When heavy valve gear on large engineswas worked at high speeds it soon becameapparent that a good deal of wear re-sulted and derangement frequently tookplace, and many breakages and other fail-ures could be traced to this cause. In order to avoid what could be avoided,valve gear was, wherever possible, re-duced in weight, and alloy steel, havingenduring qualities, was substituted for theheavier parts. In order lo carry out thissubstitution properly the dynamic aug-ment, as it is called, was studied by thosehaving to do with valve gear. This scien-tific term, more or less formidable in ap-pearance, is not so terrifying when prop-erly understood. The augment, as faras it applies to valve gear, is not essen-tially different from the same term appliedto counterbalancing. It may in general bedefined as, the tendency of reciprocating pin in forward motion, and has a constantlead.
