Abstract
To prevent vertical disengagement of the knuckles of railway car couplers, for example type "E" couplers, a vertical upward extension is provided on the forward nose of the knuckle which terminates in a shelf extending over the buffing face of the nose. The pulling face of the extension tapers upwardly toward the buffing face to allow for vertical angling thereof.
