The cam 94 has offset cam arms which are offset via spring ledge A torsion spring is secured near its middle by a screw pin assembly One leg of the spring bears against a boss on the inside of the housing 18 while the other leg bears against the spring ledge of the cam The spring thus assists in causing the thumb-turn to throw the bolt into either locked or unlocked position and not leave it in an intermediate position.

With reference to operation of the actuator member 80 from the cylinder lock and extending tang 38, there is a cam adaptor , see FIG. The cover plate also has smaller holes 26b for reception of screws. The cam adaptor receives the tang in one end and has a slotted face a on the other end which is inside the housing. A cam member has a cam arm a and internal tangs b which tangs fit into the slot a.

A locking ring fitting in groove b is utilized to hold the cam on the cam adaptor Rotating of the tang 38 will rotate the cam arm a. In operation, the cam arm a and cam arms can be positioned by their rotation to contact the end of the actuator member 80 and force it toward the strike so that lug 86 will clear stop 88 to throw the bolt to a locking position, see FIG. Similarly, when in locking position either the cam member or a cam arm can rotate in a counterclockwise direction viewed in FIG.

Because of the integral guide rails guiding the sliding bolt and the actuator member sliding with the bolt the assembly is particularly strong, reliable and smooth operating.

The entire arrangement provides an extremely strong, easy to service, smooth acting, defeat-resistant drop-bolt lock mechanism not available with the known prior art constructions.

United States Patent 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.
