Hello, I'm hoping someone can help.  I have an early Singer 12, dated 1871.  It has the tension discs about a third of the way up from the bottom of the faceplate.  There is a knob above it that manuals say to turn to adj upper thread tension.  What I don't understand is how turning that screw (which just seems to go into the faceplate, not hitting anything inside the machine) would have any effect on the tension!  When I turn it it just tightens up and has no affect on the thread tension.  Any help with understanding this would be much appreciated!

Welcome to the forum momdesert!  May I suggest a post in the "introductions" thread so we can get to know who we are talking with?

Hard to describe without a picture.  There is a connection.  The back of the two tension disks have a post that a flat piece inside the head is connected to.  As you tighten or loosen that screw you are moving the post below the screw into contact with that flat piece.  That causes it to lever against the post and create tension.  This is ALMOST ALWAYS filthy and frozen.  Disassembly and cleaning is probably required.  I will see if I can take one apart and take a picture tonight.

Yes, a picture would help.  And I'm happy to pull the faceplate from my similar machine if it will help.
