Abstract
A lock mechanism for a railway car hinge-deck section includes a locking lever pivotally attached to a railway car and having an upper and lower wedge bar alternately engageable with a wedge plate carried by the hinge-deck section when the section is displaced to a raised or lowered position, respectively. Seat means affixed to the car restrict vertical displacement of the deck section and cooperates with mating inclined surfaces on the wedge bars and wedge plate to provide positive, tight retention of the hinge-deck section in either of its locked positions.
