摘要:
Apparatus for ensuring that coupler knuckles of uncoupled rail cars are fully open before recoupling, comprising a magnet positionable in the path of the coupler knuckle of a moving rail car, the magnet being mounted so that after the knuckle engages the magnet, movement of the rail car causes the magnet to twist and move outwardly to pull the knuckle to full open position.
