how to repair arm on detrola 4 in 1 record player?

When I was moving the arm to start the player I either turned it the wrong way or too far and the spring device has come off. We have everything taken apart and have found the pieces but can not figure out how they should go back on. If we could just get a diagram showing how it should be we could fix it. Please help with this. It was a very special birthday present.
