When I had a Singer a touch and Sew, there was a little lever in the bobbin area that your moved to fill the bobbin. It had a red circle on it? I got rid of my Singer touch and sew at the time because my bobbins were worn and I couldn't find a place to buy new ones. Nowadays of course you can get spare parts on the Internet. Check the little knob thing on the bobbin bottom, is it still crisp or worn looking? For a while I could wind the bobbin by lightly pressing down on the bobbin top as it rotated to keep it in place so the worn part wouldn't slip.
