Abstract

A lock-down assembly for a hinged hatch cover having a lock strap with an arm portion projecting laterally over a hopper car roof on the side of the hatchway opposite the hatch cover hinge. An operating lever is pivotally mounted adjacent to one end between the upstanding sides of a bifurcated support mounted on the roof adjacent to one side of the projecting arm of the lock strap when the hatch cover is closed. The underside of the lever presses down on the arm with the handle of the lever extending in the fore-and-aft direction above the car roof. A clevis or shackle is pivotally mounted on the upper ends of the upstanding sides of the bifurcated support. The pivoted end of the lever opposite the handle portion has a hook formation under which the bight of the clevis or shackle has hooked engagement when the lever is in its locking position. The lever is released by pressing down on the handle to raise the hook formation sufficiently to allow the clevis to be turned up out of hooking engagement.
