Abstract
This invention relates to a railway car coupler having an improved anticreep protection assembly so as to prevent inadvertent uncoupling during movement of the railway car along a track. The improvement comprises the provision of a chamfered locklift connector or a chamfered coupler structure that lies in the path of movement of the connector so that an anticreep prong of the connector may be free to engage with a front face ledge of the coupler head to provide positive anticreep protection against accidental unlocking of the coupler.
