A lockset has a die cast, monolithic body pivotally supporting a lever handle which upon actuation and through fingers engages tabs of a lock bolt assembly for selective linear retraction of the latter. A rotatable knob carried by the body through a spindle and a guide plate mounts a cam plate which acts, upon rotation of the knob in either direction, to retract the bolt assembly. The bolt has opposed U-shaped guides which receive the guide plate and guide the bolt laterally and vertically. A lock has a lock lever which positively engages the bolt assembly to lock the latter in place. A follower lever and the lock lever are pivoted about a common axis. The follower responds to a barrel lock between two positions to lock and unlock the lock lever from the bolt assembly. The lock lever also responds to a latch pin independently of the follower on the opposite side of the lockset from the barrel lock, to lock and unlock the bolt assembly. A monolithic lock strike has lateral passages for receiving shanks of an interlock bar. Heads of the interlock bar interfere with the strike to resist forces separating the lock strike from the lockset.

An improved lockset for mounting in a door and securing the door in a jamb, the lockset having a jamb end, an interior end opposite the jamb end, an outside for facing the outside of the door, and an inside for facing the inside of the door, the improvement comprising: a. a monolithic body having a head with a straight line channel proximate the jamb end; b. a lock bolt assembly in the channel of the body for translation along a path between a retracted and an extended position, the extended position having a portion of the lock bolt externally of the body on the jamb side thereof for receipt in a mortise of the jamb, the retracted position having the lock bolt withdrawn from the extended position for clearance of the mortise, the lock bolt assembly having U-shaped in cross section guides on the interior end of the lockset and facing the path; c. a guide plte overlying the lock bolt assembly on the inside of the lockset, abutting the head of the body and secured to the body, capturing the lock bolt assembly in the channel, and received by the guides for maintaining the interior end of the lock bolt assembly along the path; d. means for biasing the lock bolt assembly into its extended position; e. means on the inside of the lockset for manually retracting the lock bolt assembly; f. means on the outside of the lockset for manually retracting the lock bolt assembly; and g. means for locking and unlocking the lockset from either side thereof. For use in a door jamb to receive a lock bolt of a lockset mounted in a door, an improved strike comprising: a one-piece member having ends adapted to be mounted to the door jamb, a medial section raised from a plane containing surfaces of the ends, a curl in the medial section for transit bearing with a lock bolt upon closing of the door, the curl having a convex outward curvature, a mortise in the medial section having a primary and a secondary lock bolt bearing surface, the secondary surface being a redundant surface to keep a lock bolt upon failure of the primary surface, a pair of spaced apart retaining sections in the medial section, each retaining section having a slot for receipt of a shank of an interlock attached to the lockset, a head of the interlock residing behind the retaining section for interference therewith upon loads in the jamb and the door tending to separate the two.
