Railway vehicle coupler

A method of manufacturing a knuckle of a coupler of a rail vehicle, the method comprising:

• forming a leading beam having a pulling face;
• extending a lateral offset beam from the leading beam;
• extending a tail from the lateral offset beam;
• extending an extension wall from the lateral offset beam towards an end of the tail;
• and
• extending a tapered lock engagement wall from the extension wall to the end of the tail, wherein said extending the tapered lock engagement wall comprises angling the tapered lock engagement wall in relation to the extension wall,
• wherein the tapered lock engagement wall is configured to engage an interior face of a main body of a lock of the coupler, wherein the interior face defines a knuckle-engaging surface that is configured to bear against the tapered lock engagement wall.

A coupler of a rail vehicle, the coupler comprising:

• a lock including a main body having an interior face defining a knuckle-engaging surface;
• and
• a knuckle comprising:
• a leading beam having a pulling face;
• a lateral offset beam extending from the leading beam;
• a tail extending from the lateral offset beam;
• an extension wall extending from the lateral offset beam towards an end of the tail;
• and
• a tapered lock engagement wall extending from the extension wall to the end of the tail, the tapered lock engagement wall being angled in relation to the extension wall,
• wherein the tapered lock engagement wall engages an interior face of a main body of a lock of the coupler, and
• wherein the knuckle-engaging surface bears against the tapered lock engagement wall.
