Abstract
A mechanism for locking the lock straps of railway car hatch covers includes a pivoted lever which is clamped over the tongue of a lock strap. The clamping is achieved by means of a pivoted keeper member having a mouth portion engaging the ends of the lever in locking relation. The keeper member is pivotally supported and is positioned by an overcenter toggle action in a receiving or locked position by means of a leaf spring assembly. The locking and unlocking action may be accomplished by hand or foot operation.
