Abstract
A hatch cover locking mechanism for securing a roof member onto a hatch opening of a railway hopper car is provided. The hatch cover lock utilizes camming engagement between an operation handle and a keeper member in order to lock or unlock the keeper member over a hinge pin associated with the hatch roof member. A hook rotates along an orientation generally the same as that of the keeper, and the hook retains the hinge pin as desired when the hinge pin is not locked down by the keeper.
