Please Help! Trying to reassemble lock, 2 extra pieces!

[nycsd]

Hello, I am not at all experienced with locks. Just moved into a new apartment, and our lock was disassembled. Trying to put it back together, and cannot find a diagram for this particular lock anywhere (is it a type of Mortise lock?). I have assembled it so it seems to loosely work, but there are 2 extra pieces (circled in red, a spring and small metal piece). I cannot figure out how to position them. ANY ideas would be greatly appreciated!

Are you sure all parts are present? Can see where the small part with the two holes probably goes, and could probably figure out the bolt spring. But I don't see the long bolt that would lock the cylinder in place.

Thank you for the reply. You are right, there were 2 additional screws missing.

Fortunately, the building found a spare lock and was able to replace the whole unit. So I no longer have the broken lock.

This will be hard to explain in words.

The small part with the two holes sits in the slot next to the circular hole where the cylinder screws in. It will be standing on its end. When you put the cover back on, it will fit in the same slot on the cover. If you look at the cylinder hole like the "female" symbol, it will go in the slot that forms a "+". So it will span from the bottom to the top cover. Looks like you're missing the set screw though. There is a long screw that will go from the edge plate through the bridge (the part with two holes), and into the cylinder to keep it from being unscrewed. It it's difficult to screw in, stop and flip the bridge around the other way.

The spring goes on the bottom of the bolt. The "u" shaped end goes around the oblong peg. The short curved end goes around the round peg. The rest of the spring rests on the "Y" shaped part, providing tension to it.

I have a plane to catch, so if somebody doesn't beat me to it, I'll dig up a diagram later tonight, which will make things much easier to understand. In the mean time, if you Google something like "mortise lock deadbolt exploded diagram", click on "images," and you should see a lot of examples. Most are more complex, but you'll get the idea.

Guess you found the answer while I was typing mine. Glad you got a replacement.

Thank you so much for the explanation! Even though I got a replacement, I was still dying to know how to fix it after trying to figure it out for so long. Makes sense now. Thanks again!
