windshield wipers

hello:
I have a 1952 200 and I wonder why when I use my wipers they go up when I turn the knob and they go down when I turn the knob, but once they are up they don't go down automaticly. I have to turn the knob for the wiper to move back down.
I know there is directions in the literature to lubricate the wipers , which I have done.
thanks
