Abstract
A lock assembly kit including components capable of being assembled to a railcar gate assembly including a frame defining a discharge opening and having a pair of generally parallel, free ended and stationary rigid racks extending from one end of the frame away from said discharge opening, a gate mounted on said frame for sliding movements along a predetermined path of travel between open and closed positions and relative to the discharge opening, and a drive mechanism for moving and movable with the gate between the open and closed positions thereof. The lock assembly kit includes a control shaft mounted adjacent the free ends of the racks and which is provided with operating handles radially extending from and secured to the control shaft. A stop mounted for movement between locking and unlocking conditions. The stop extends into the path of travel of the gate when in the locking condition thereby operably preventing inadvertent movement of the gate from the closed position toward the open position. The stop is movable with the control shaft. The lock assembly kit further includes a spring biased latching mechanism for positively maintaining the stop in the unlocking condition until after the gate moves a predetermined distance from the closed position.
