Back in October, my fiancee and I purchased a home built in 1883 and have slowly been making the interior into what we want it to be. I went to disassemble the door latch for the first of our project rooms, because the latch bolt itself refused to come back out. What greeted me is in the linked album below.After some google research, I'm not sure but I may have more questions than I started with. For starters, it looks like mortise-style latches are (were) available in as many forms as there are stars in the sky, with varying numbers of springs. So I'm not certain exactly how accurate any information I find will be for this particular latch. The only springs present in this case were a small coil spring below the knob shaft, and a...tab? shim? leaf? spring that I'm holding in the first image, which has a little bend at the end. It looks like this spring could have been used for the lock bolt, but some of the images I've found use a similar-looking spring to return the latch, so I'm uncertain.I suppose the main question would be whether or not I'm missing any additional springs, but any information you can give me is appreciated. A few quick addenda:- The latch bolt appears to have been installed backwards by whoever last opened the casing. The long, flat edge is facing the doorway, rending the angled face useless.- The "rocker" on the shaft has a little nub sticking off between the two "rocker arms". Does this relate to any spring? I wouldn't think so, but I can't think of any function it may perform.- I don't know who made this latch (I guess Sanger was a common manufacturer?) but the number 7585 is stamped on the inside, with a 2 below that (when the number is viewed oriented "right-way up"; the linked images show it runs vertically read from bottom to top)IMAGES: https://ift.tt/2uNU2b2 via /r/DIY https://ift.tt/2LyKjMS
