Prominent among those oddities werecertain locomotives built by David Clark,with a link motion and independent cut-off valve. This gear had six eccentrics,straps and rods, four rock shafts, two re-verse levers and rods, two additionalvalves, valve seats, valve steins and stuf-fing boxes. The motion is illustrated inFig. 3.
