Also found a pair of feet that were made under a 1946 patent. The patent no is 2394873. The patent refers to "applique", however in reading it I feel they are certainly meaning sewing on binding. The patent photo (included when I sell them) shows the braiding being threaded through the slots of the foot. There is also a tiny "slider" which goes into the end of both the feet. This slides up to the braiding to keep it securely taunt. Very interesting!
I did try them both on my vintage low shank machines, and also on a new Singer. Worked as it said. What a nice part of sewing machine history. Evidently didn't make a lot.
Also found a nice assortment of wrenches, and screw drivers. One goes to a vintage Singer puzzle box with the spiral end. Also tossed in this photo is a high shank gathering/shirring foot. Also interesting is a machine threader of sorts. It is attached to the presser bar, appears to be screwed to tighten. Then it swings down to thread the needle. Can still see a tiny threader.
Last of my finds is a Singer 66-1 cording/zipper foot.
