Abstract: A safe door lock with a servo motor operated cam is described. A retracting lever is pivotally secured to the locking bolt and is displaced on a pivot connection with the bolt by the cam. The position of the cam and the bolt are detected by microswitches. When the retracting lever is in a locking position, the bolt cannot be retracted within the lock housing. The cam is operated by a servo motor and locked in position by the gear train which includes a worm gear. The locking bolt may be a slam bolt having a spring biased latch which slides therewith or the locking bolt may be a deadbolt when the lock is used with a boltwork system of a vault door.

Abstract: A vehicle rack for securement over the roof of a vehicle is described. The rack comprises a support rail having opposed supporting brackets for maintaining the rail elevated transversely over a vehicle roof. The brackets are removably connected to a respective one of a pair of connecting bases. Each of the connecting bases is attached to a restraining portion of a vehicle adjacent the roof thereof with the connecting bases positioned on a respective side of the roof. The connecting bases are interconnected by a flexible connecting strap which extends therebetween. A tension force is applied between the attachments of the pair of connecting bases to rigidly connect the bases on the roof. One of the connecting bases is a locking base provided with a latch engageable element. One of the supporting brackets is a locking bracket having a latch mechanism actuable by a lever arm for engaging the latch engageable element of the locking base to immovably secure the brackets to the connecting bases.
