As soon as the bucket rests on the carrying rope, the pins arereleased from the guide rail, and the pawls fall down in position overthe hauling rope. As a knot approaches it lifts the first pawl, which,however, falls back into its original position ; but the second one resists,and the bucket is automatically taken in tow. To avoid a violent impact,of the knot upon the coupling, the shunter gets a bell-signal when aknot is approaching, and he pushes off the bucket at about the samevelocity as the rope is travelling. The uncoupling is similarly the bucket nears the station, the pawl pins come in contact witha guide rail, lifting the pawls out of gear, and releasing the hauling rope; :22 MACHINERY FOR METALLIFEROUS MINES. the bucket, by virtue of its momentum, then moves off the c
