I have a problem with the Baldwin lock on my front door. I do not know
the model number. It was installed in the past 20 years. I looked at
some sites to identify it, but do not find an exact match. It is
similar to the Atlanta model shown here:
The lock is a mortise lock. On the outside there is a hand grip and
thumb piece above it and a key cylinder above the thumb piece. On the
inside there is a round knob and a key cylinder above it. Looking at
the door edge, there is a deadbolt near the top, a latch mechanism
(don't know the real name of this part) below, and two buttons below
the latch mechanism. If the bottom button is pushed, the thumb piece
on the outside of the door can be pressed down to open the door if the
deadbolt is not engaged.
The problem is that when the thumb piece on the outside is pressed
down, it draws in the latch mechanism, but leaves about ¼ inch of the
latch protruding outside the door. The inside knob can be twisted to
withdraw the latch almost all the way into the door. The latch is free
to move because it can be pressed in easily with your finger.
Before I tear into the lock, can anyone offer guidance as to what is
wrong and how best to proceed ?
