Abstract: A preferably self-lubricating plastic slide frame is secured on the main frame part straddling the pivotal thumb lever inner end and includes a vertical guide track slidably mounting an actuating yoke downwardly engaged over the thumb lever inner end and upwardly abutting and overlying, pivotal actuating lever. The slide frame also includes a vertical guide track slidably mounting a stepped bar-like slide which downwardly abuts the actuating lever and is upwardly stepped engaged with a crank arm of a rotatable spindle assembly, one of the steps of the slide projecting rearwardly through the slot of a cover for additional guiding thereof. An inverted L-shaped leaf spring is engaged with a side of the slide frame and an underside of the actuating lever normally urging the actuating lever pivotally downwardly for ''''at rest'''' positioning of the actuating lever, actuating yoke and thumb lever. The spindle assembly includes a hollow cylindrical spindle retainer having alternate sockets therein positioning a half-round spindle in resiliently retained, but removable, alternate positions for properly engaging a latch from either latch side.

Abstract: A bolt is moved by a driving lever pivoted on the bolt and through a transverse pin to a slotted rotatable driving member, the driving lever pin being guided in movement in the driving member slot by extension thereof transversely through an inverted U-shaped guide slot in the latch frame. The forward downward end portion of the guide slot is rearwardly undercut in its downward extension. The operating lever is rotatable through a transverse driving shaft transversely slidably engaged therewith, the driving shaft being, in turn, rotated through a key operated lock cylinder connected to the shaft through a usual lost motion arrangement. The driving shaft is D-shaped cross section engageable in a D-shaped cross section opening of the driving member. Anti-violation plates of unique form are positioned beneath usual rosette and cover plates resisting shearing of the lock cylinder frame.
