Mortise lock with dual reverse/lockout mechanism

A mortise lock, comprising:

• a housing;
• a latch bolt slideably retractable into said housing;
• a latch actuator assembly including
• a first latch actuator mounted within said housing for rotation about a first axis and keyed to an outer door operator for translating rotary motion of said outer door operator from a rest position into linear retraction of said latch bolt, and
• a second latch actuator mounted within said housing for rotation about said first axis and keyed to an inner door operator for translating rotary motion of said inner door operator from a rest position into linear retraction of said latch bolt;
• and
• a powerpack engaged to said latch actuator assembly for biasing said inner and outer door operators back to said rest positions, said powerpack further comprising,
• a first pinion engageable with said first latch actuator and rotatably mounted in said housing on a second axis for rotation between a first position in which said outer door operator is in said rest position and a second position in which said outer door operator is displaced from said rest position sufficiently to retract said latch bolt,
• a first spring engaged to said first pinion for biasing said first pinion toward said first position, and
• a first pinion catch offset from said second axis for engaging said first latch actuator, and
• a second pinion engageable with said second latch actuator, said second pinion being rotatably mounted in said housing coaxial with said first pinion for rotation between a first position in which said inner door operator is in said rest position and a second position in which said inner door operator is displaced from said rest position to retract said latch bolt,
• a second spring engaged to said second pinion for biasing said second pinion toward said first position, and
• a second pinion catch offset from said second axis for engaging said second latch actuator.
