Abstract

A flush bolt with improved travel is disclosed. The flush bolt is composed of a housing with a slotted longitudinal cavity in its face and a bore at least partially through one end of the housing and passing far enough through the housing as to engage with the slot. A bolt is within the bore and a coupling lever is rotatably coupled to a bolt at one end and to a slotted actuator arm at a centrally located point. The slotted actuator arm is coupled at one end to the housing at a point centrally located within the longitudinal cavity so that when pivoted, the slotted actuator arm transfers its pivotal movement to angular movement in the coupling lever and, in turn, into linear motion of the bolt.
