Abstract: A lock with a keyed removable plug having a substantially cylindrical body, and a plurality of tumblers disposed within the body and movable between a first position retracted within the cylindrical body of the plug and a second position with one end extending from the body. A retaining tab extends radially from the plug body at an angle from the radial orientation of the tumblers. A shell has a substantially cylindrical opening therein for removably receiving the plug in a first shell end. The shell further includes an annular shoulder spaced from the first shell end and engageable by the plug retaining tab and a retaining one of the tumblers when in its second position. Tumbler grooves extend axially along the sides of the shell opening from the first shell end to a groove end short of the shoulder, and a release groove extends axially along the shell opening from the first shell end to the shoulder to define an opening in the shoulder.

Abstract: A slam-capable rotary latch employs a single rotary jaw that is releasably retained in its latched position by a rotary pawl, with the latch having a pair of spaced housing side plates that sandwich the rotary jaw and the rotary pawl, with the side plates defining aligned first and second U-shaped notches that cooperate with a third U-shaped notch formed in the rotary jaw for concurrently receiving and latchingly retaining within the confines of the first, second and third U-shaped notches a suitably configured strike formation, with housing side plate portions that define a selected one of the first and second U-shaped notches being rigidified and strengthened by the close proximity presence of a flange 1) that is formed integrally with side plate portions that define the selected notch and 2) that extends transversely to bridge between the housing side plates at a location near the first and second U-shaped notches.

Abstract: A bolt lock including a lock barrel having a central opening cylindrical about a central axis and extending between an open front end and a closed rear end. The lock barrel has bolt openings extending outwardly from opposite sides of the central opening adjacent the lock barrel rear end, with a pair of bolts received in opposite bolt openings. Each bolt has a head on one end, a leg on the other end with a rear side having a spring groove, and a front side with an axially extending shoulder. The bolt shoulders are planar and parallel to one another. The spring grooves are open at the end of the leg and parallel to and equidistant from a radius of the central axis. The bolts have their other ends in the central opening adjacent one another with the bolt legs substantially side by side when in a retracted position.

Abstract: A combined lock/actuator for providing linear actuation including a lock barrel having an opening extending along a longitudinal axis, a spline in the opening extending along the longitudinal axis, a plug mounted in the opening, and a key-retractable tumbler carried by the plug and extending into the spline. The plug is rotatable within the opening over a fixed annular displacement between an actuation position and a release position. Further, the plug is translatable within the opening over a fixed axial displacement along the longitudinal axis between a first position and a second position. The tumbler extends into the spline when the plug is in the actuation position in the first position, when the plug is in the actuation position in the second position, and when the plug is in the actuation position in translating between the first and second positions.

Abstract: A racking resistant door control mechanism for securing a pivoted door employs an elongate lock rod that extends the height of the door and is journaled for pivotal movement by bearing assemblies having steel covers that enclose plastic bearing liners. The lock rod has upper and lower cam-type latch members welded to its opposite ends for engaging keeper members carried by upper and lower parts of a door frame for holding the door closed. The lock rod extends through and is welded to a steel sleeve at a location spaced a short distance upwardly from the lower latch member. If the lock rod is formed from two elongate elements instead of one, the sleeve is welded to both to aid in forming a connection therebetween. Racking resistance is provided by locating the sleeve and the bearing assemblies such that the steel covers of the bearing assemblies are held in engagement with the latch members and with opposite ends of the sleeve.

Abstract: A racking resistant door control mechanism for securing a pivoted door employs an elongate lock rod that extends the height of the door, is journaled for pivotal movement about a lock rod axis by door mounted bearing assemblies, and has cam type latch members welded to its opposite ends for engaging keeper members carried by upper and lower parts of a door frame. The cam and keeper members feature novel, compact arrangements of interengageable formations that are located on opposite sides of, but relatively near to, the lock rod axis of the locked door--formations that cooperate in bringing the door to its fully closed position, in securely retaining the door closed, in preventing racking movements of the closed door and its adjacent door frame, and in breaking the door open when ice formations, cold seals or the like resist initial opening movement of the door.

Abstract: A push button lock for mounting at an opening formed through a door panel near an edge of the door includes a flush mountable exterior housing having a thin mounting flange that encircles central housing portions that are configured to extend into the door panel opening, and a surface mountable interior housing that defines a bolt passage that carries a spring-projected slide bolt having an end formation configured to latchingly engage a suitably configured striker. The interior housing and the mounting flange of the exterior housing overlap and are clamped toward engagement with interior and exterior door panel portions that extend about the opening.

Abstract: A handle operated, heavy duty, toggle type draw latch is mountable on one of two members and is operable to selectively engage and disengage a latch-engageable formation connected to the other of the two members. The latch includes a complexly configured operating handle that is pivotally connected near one end to a mounting base for movement relative to the base between closed and open positions, that provides a hand grip near its opposite end, and that, at locations between its opposite ends pivotally mounts a drawbar for movement between extended and retracted positions, and defines not only a plurality of stops but also a catch-engageable formation. One stop engages the base when the handle is closed. Another stop engages the base when the handle is fully open. Still another stop engages the drawbar when the drawbar is retracted. When the handle is open, the drawbar can be pivoted into and out of extended positions for selectively embracing the latch-engageable formation.

Abstract: A slam-capable rotary latch employs a single rotary jaw that is releasably retained in its latched position by a rotary pawl, with the latch having a pair of spaced housing side plates that sandwich the rotary jaw and the rotary pawl, with the side plates defining aligned first and second U-shaped notches that cooperate with a third U-shaped notch formed in the rotary jaw for concurrently receiving and latchingly retaining within the confines of the first, second and third U-shaped notches a suitably configured strike formation, with housing side plate portions that define a selected one of the first and second U-shaped notches being rigidified and strengthened by the close proximity presence of a flange 1) that is formed integrally with side plate portions that define the selected notch and 2) that extends transversely to bridge between the housing side plates at a location near the first and second U-shaped notches.
