SOURCE: The knob on wheel stuck.
Remove the needle, and place a screwdriver or something like it under the needle bar to keep the wheel from turning.
Wrap the knob in some type of fabric to keep it from being marred.
Using channel locks or water pump pliers, grasp the knob and turn it to the left. It should come loose. Once it is loosened, try it 2 or 3 times to make sure it works as it should.
Wind the bobbin, insert a new needle and have fun again.

Wind the Bobbin
For the usual jobs, it is the best to use a medium sized thread.
2. Disengage the flywheel by unscrewing the coupling knob as far as it will go.
3. Place the bobbin on the bobbin winder, and push the bobbin winder to the right.
4. Pull out one of the spool pins and place the spool of thread on it.
5. Pass the thread through the bobbin winder tension discs, as indicated.
6. Wind the end of the thread around the bobbin by hand, in the direction indicated.
7. Wind the bobbin, at a medium speed by pressing lightly with a finger on the spool so as to stretch the thread better and thus fill the bobbin to a maximum. The full bobbin stops automatically.
8. Re-engage the flywheel by tightening the coupling knob.
9. Cut the thread and remove the bobbin from the bobbin winder by pushing the latter to the left.

SOURCE: Bobbin won't wind Singer 7422
Your problem lies with the main shaft that is to tight to release the bobbin winder mechanism, because of old grease and oil becoming sticky. A short term solution will be to remove the needle, in order not to hurt you, and then hold on to the needle bar with your left hand, while engaging the bobbin lever with your left hand. This will prevent the main shaft to rotate and your winder should work. In the long term, take it to your dealer to clean the oil and grease. You will not be able to open the machine casing yourselve, as you might damage the casing and or electronics.

I just figured out why my bobbine was winding on shaft instead of on the bobbin. first of all make sure the bobbin is setting up high enough, top of bobbin needs to be a fraction higher then the bobbin shuttle, next check to make sure there are no burrs on the bobbin, then make sure that the thear is catching in the groove (**** in top) of the bobbin. In order to get mine to wind i had to lett the tread go down and then slip the thread in the groove. also remember to leave the pressure foot up do not put it down. let me know if this helps.
