Oscillation

One of the claims made for the Fairlie's Patent locomotive was reduced "oscillation" whatever that is.
This claim was made in several newspaper in far off N. S. Wales, etc. [1]
Hammer blow[edit]
Steam engines have unbalanced wheels because of the driving and coupling rods. This is one kind of oscillation. Counterweights can balance out the top-down hammer blow, but this causes forward-aft jerkiness. In practice some counterwieghts are provided so that there is some hammer-blow and some jerkiness.
