I just purchase a Singer 301 and cant get the bobbin case out

Clean the bobbin housing for any dirt. Check the tension of upper thread whether correctly set or not. May be this is time for servicing.

See higher up for a possible answer.

First make sure that the needle is fully up (use the hand-wheel). Move the bobbin cover release button to the right and lift the bobbin cover out of the way. Remove the current bobbin, if needed. Hold the new, full bobbin so that the thread comes off the bobbin counter-clockwise when you pull the thread. Place the bobbin into the bobbin case. Pull the thread through the slot near the bottom of the case and to the left. Place a finger on top of the bobbin. Next bring the thread left further towards the back of the bobbin case until it stops in the second slot (near the 8 o'clock position if you compare the position to a 12-hour analog clock). Pull the thread back through the groove in the cover plate until it is cut by the thread cutter at the top left of the cover plate. (The thread will turn a "corner" to the cutter.) Replace the bobbin cover.

Singer has the manual for most of their sewing machines here: http://www.singerco.com/support/instruction-manuals . The direct link to the manual for the 90S is http://www.singerco.com/uploads/download/26e7243ab52aaed42904377fea7b090541eb0c9b.pdf . See pages 16-17 (page 18 in the PDF for the English description) and pictures that may be better than the verbal description.

I hope this helps.

Make sure to use a brand new needle.
ALWAYS RAISE the presser foot when threading.
Unthread and re-thread from the beginning.
Verify the thread path is correct.
Set the upper tension to midway between High & Low numbers.
Verify the bobbin is loaded and threaded correctly in the bobbin case.
Begin sewing slowly and check the result. The upper tension can be tweaked so the upper & bobbin threads meet in the middle of the fabric.

If it is still not working properly, the machine may be out of time and require service.

Try a ball point 11/70 or stretch 11/70 needle. Also rethread the entire machine. Make sure the needle is inserted correctly in the sewing machine. I had this same thing happen to me recently and I found I had the needle backwards.

It sounds like your timing is in need of adjustment and unfortunately you need special tools and know how. So, you have to take it in for service.

I just had this problem, too - if you have the manual, check out page 15. If you have removed the throat plate, you need to make sure that the position finger on the bobbin case base enters a notch on the underside of the throat plate. Fixed my problem right away.

Just an FYI-the bobbin thread needs to match your top thread. The majority of the thread that appears in the top of your embroidery actually IS the bobbin thread. The machine is working correctly. Don't use a bobbin full of white thread-instead, thread a bobbin with the color your doing the embroidery work in to match and you will have a perfectly beautiful embroidery.

More than likely you have a broken vertical shaft gear.

When you turn the handwheel you should see the sewing hook moving under the bobbin case.

If not, take it to a sewing repair person and it should cost somewhere around $100 to repair.

The Singer 301 uses the same bobbin as the Singer 221 (also known as a Featherweight). Not surprisingly it's called a Class 221/301 bobbin and is Singer part number 45785. If you don't have a Singer dealer or large sewing machine repair shop in your area, I would suggest purchasing from a reputable online seller such as Vintage Sewing or Sewing Machine 221 Sale. Below is a picture of what both the older and newer style of this bobbin looks like.
