Abstract: The dogging device comprises a detented dogging hook, for engaging a latching and unlatching control rod of a panic exit latch and actuator assembly, or a like assembly, and comprises means for selectively changing the operator-implements thereof from one type to another. The method comprises the steps of forming such a changeable dogging device. The kit sets forth the components parts cooperative with a basic dogging device for adapting the latter for use with any one of a plurality of operator-implements.

Abstract: The device comprises a latching assembly enclosed within, and translatable relative to, a centercase housing; the housing is mounted on a chassis. The device is adapted for cooperative engagement with a locking cylinder, for actuating the latching assembly, and for operation of a thumbpiece lift, by an ancillary, external, trim linkage, for translating the latching assembly. The latching device has a master, locking cylinder cam or dowel, the latter having a removable screw, which (through a locking cylinder) either operates a night-latch cam plate, to translate the latching assembly or, upon removal of the screw, allows the cam or dowel to translate a tumbler which, in turn, frees a thumbpiece lift, for operation (then) of the latching assembly by the lift, instead of by the cam plate. Accordingly, with the drive screw in place, the external, operating trim linkage can not operate the device; it must be unlatched, externally, by a key in the locking cylinder.
