Saw this machine on CL and I don't think I've ever seen those lumps with screws on top of a machine like this. What is that?

I don't know the brand of machine but I have the little crown thingy for thread tension on my Minnesota Model D hand crank..... kool machine!

I have a New Williams machine which was made in Quebec, Canada in the late 1800's with the exact same type of thing on the top. I believe that is somehow to add tension to the thread as you are sewing.

That is the top thread tension. I can't see exactly how that one is made, but center it so the ends on the pedistals and then you run the thread from the spool on the right to the tensioner. There should be two pieces to the tensioner spring ( the large flat part held by the screw) and the thread passes between it. As you turn the screw in it tightens the tension, backing it out reduces it.

My New Home has that style. Works good, but is not controlled by the presser foot lifter as in other type.

Also if you soak your attachments and the unpainted pieces in Evapo-Rust it will clean them up and they'll look better.

It is called a Leaf Spring Tension. That type tension is frequently found on New Home machines, I don't care for the look of it and my BFF who refurbs machines despises it.
