  • Railway Coupler Shank Keyslot Contour
    Patent number: RE29011
    Abstract: The keyslot of a railway coupler shank is modified to eliminate the interference between the coupler shank and draft key during conditions of buff or draft during vertical curve negotiation of the cars when traversing uneven track. The upper and lower walls of the keyslot diverge from the rear bearing surface of the keyslot adjacent the butt of the coupler shank. Thus the keyslot opening is wider in the front portion than at the rear portion.
