DEFINITION

Classification: 213/109

A type of coupler now used on the railroads of this country and known as the Janney type, which consists essentially of a coupling head having a guard arm on one side and an angular knuckle pivoted to the other side thereof, one of the legs of the knuckle being the coupling part and the other the knuckle tail, and means to lock the knuckle in coupling position. This means usually engages the knuckle tail. More highly developed couplers of this type have additional features, as is indicated by some of the subclasses indented hereunder.
