ABSTRACT:
A knuckle railway car coupler includes latching means for maintaining the coupler locked when the coupler is placed in an inverted position. The latching means includes a latching member connected to the lever of the rotary lock-lift assembly of the coupler and is supported thereon in an inoperative position when the coupler is in its normal, upright working position. An abutment member extends into the chamber defined by the coupler head. The latching member is spaced from the abutment member in the inoperative position and moves into engagement therewith when the coupler is inverted to prevent rotation of the lock-lift assembly and subsequent movement of the coupler lock between locking and unlocking positions.
