You want to have this lever in its highest position, by turning the large flywheel at the other end of the sewing machine. This is an arm that sticks out from a vertical slot in the face plate it has a hole at the end. Above all of these pieces is the "take-up lever", shown in the manual. Just above the tension regulator is a piece of heavy-duty metal sticking straight out from the face plate, and is then bent at a right angle to the left, over the top of the tension regulator - this doesn't move at all. Directly to the right of the tension regulator is a flimsy-looking wire that looks a bit like a thin paperclip that's been bent out of shape this moves up and down slightly.

Most of the next few parts are not shown or described in the manual, so you'll have to bear with me here. You'll see that it's two round plates held together with a spiral spring where you can adjust the pressure.
HOW TO THREAD ATLAS DELUXE SEWING MACHINE MANUAL
On page 2 of the manual is part #6, sticking out like a knob, identified on page 3 as the "thread tension regulator". On the left side of the face plate are a lot of gizmos that I'll try to describe using the instruction manual for reference where possible. You want to start threading by pulling the thread down from the left notch, the one toward the back. The notch on your right, toward the front, is just for filling a bobbin. First turn the machine to look at the face plate. I suggest looking at these to help orient yourself. Oc4ever has linked to an instruction manual with pictures that are somewhat helpful but a little hard to decipher. The "face plate" where you will thread it is mounted on the left side rather than on the front. When I bought the machine the salesman told me that Japanese Universal machines were knock-offs of older Singers, and worked exactly the same way. It has a small "Made in Japan" plate attached, but the motor has a "Made in USA" plate attached. I have a Universal sewing machine that dates probably from the 1930s.
