I have a mortise lock and recently the dead bolt part will slide out
without turning the cylinder lock. This will cause the bolt to be stucked
on the dummy side of the double door and the door won't open.

I took it apart and found the problem. There is a spring/hinge thingie
that is broken...here is a picture of where it should be:

I can get you one for $135.

I believe that is a form of a torsion spring. You may find something
similar in a good hardware store, or a similar sized one someplace. I've
seen springs of that style, but right now I can't recall where. You can
also buy something called "music wire" at a hobby shop and form your own.
