ABSTRACT:
A mechanism for smoothly and reliably operating a drop-bolt lock in which the drop-bolt operating mechanism includes a slidable bolt member carrying a cross slidable biased actuator member operable by cams for smooth sliding operation. Guide rails guide the sliding movement of the bolt member and the actuator member it carries, but the guides include a stop for cooperating with a lug on the actuator member to stop movement of the bolt unless and until the actuator member is forced away from the stop.
