The leaf spring is so constructed and mounted that when respective articles are supported in both forward and rear spaces in the cradle, the article supported in the relatively forward space flattens the spring to an inactive disposition, but when that article is dropped from the cradle by angularly moving the cradle through a first increment, the spring erects so as to prevent the article supported in the relatively rearward space from being slid o…
