Miriam,
Remember a couple years ago you told us about that free Kenmore on CL here in Springfield? Well that one had the feed dog pin and parts seized solid. It took Tri-Flow, lots of heat, and some tapping with a hammer and wooden rod to coax it to move. There was some rust in there. No idea how the rust got under the bed in that spot, but there it was.
That dried oil in Miriam's pics is why we use and recommend Tri-Flow oil so much.

Tri-Flow or Kroil seem to flow into the cracks better than anything. Not only does that pin have to go in and out but the parts of the shaft the pin rides in have to break away from each other when you drop the dogs. Shaft minus the piston. Kind of exaggerated opening so you can see it - the two chambers have to ride on that piston the dogs can break away when the tapered end of the piston is in line with one of the chambers.

The thumb screw for the Singer 301 is right next to the bobbin - big thumb screw with a slot - at least on mine. The feed dogs actually break away under the machine. I can't think of any other machine that drops from the end like that. There are some more modern machines the feed dogs drop from the front of the machine near the bobbin.

You can not see the end of that piston - the piston is pulled in and the dogs will drop - the taper of the pin keeps them from dropping too far - see picture above of the pin removed. The taper of the pin will allow for that silk setting, too.

Miriam I've always called that the feed dog bullet. I use 90% rubbing alcohol for cleaning innards /unders and it has never taken me more than a few drops and a few minutes to unstick one of these. The alcohol works so much faster than oil because it dissolves old oil and gunk almost so fast you can watch it work.
