As the foot feed is pressed the linkage slides up and down the wire without moving it. The clamp on the end Bill referred to is called a wire or cable stop. It simply clamps to the wire to keep it from pulling through the hole in the linkage when you pull the knob. The set up is a bit more obvious on my '38.
