how can i fix my jones 641 sewing machine?

I have a Jones 641 sewing machine and i am unable to wind the bobbin.I could only wind it with the needle going up and down,the same problem Gemma was having. I have oiled it as suggested by (drivewithken). I have managed to stop the needle going up and down, its making all the right noises, the small black wheel is touching the large balance wheel which is turning but the small black wheel does not, but i can turn it by hand ? Now it will not even wind with the needle going up and down either?..can anyone help me ...sheila
