Abstract: The dead bolt assembly of this invention features a novel cam activating assembly which permits election of one of two door knob spindle backsets which are in standard usage without the need for substituting different operating assemblies or reversing cylinder or thumbturn spindle components. The cam activating assembly features two parallel rotatably mounted cams which operate about two separate and parallel axes which are the centers of the two spindle backset in common industry usage. The two cams accept the door cylinder drive bar in one of the two predetermined backset positions. Each cam is capable of independently operating the latchbolt in either direction of rotation through coupled opposed cam surface which coact with the latch operating plate in conjunction with a coupling idler to convert the rotary motion of the cams to the reciprocating motion required to extend or retract the bolt.

Abstract: The lock mechanism has a spring and cam assembly provided for returning the lock plunger assembly of the mechanism from a locked to an unlocked position thereof. In addition, however, the spring and cam assembly carries an enlongated limb. When the lock plunger assembly is translated to a locked position, it forces the limb to extend from the spring and cam assembly to a disposition in which it blocks a knob catch which is carried in the outside spindle of the mechanism. Accordingly, for being blocked by the limb, the knob catch cannot be depressed and, consequently, the knob which is latchingly engaged by the catch, cannot be removed from the outside spindle whenever the mechanism is in its locked disposition. The spring and cam assembly comprises a compact unit which is slidably received in the outside spindle and confiningly supports the limb therewithin for extension therefrom into obstruction of the knob catch.

Abstract: The arrangement comprises a standard, door knob-operated, latch mechanism in which the cylindrical shank of the door knob is slidably engaged with the rotatable spindle of the mechanism, and the spindle has a spring-biased catch projecting therethrough which passes into a slot formed in the cylindrical shank of the knob. In this way, the knob is secured on the shank. The improvement comprises forming a ramp in a cut-out on the terminal or outermost end of of the cylindrical shank, and forming a complimentary bevel on a corner of the projecting catch. Accordingly, when the knob is slidably forced onto its spindle, during manufacturing assembly, the ramp formed in the cut-out engages the bevel and, consequently, depresses the catch to allow the cylindrical shank to slide thereupon and thereover, and to allow the catch latchingly to engage the slot.
