ABSTRACT:
A rotary gate control assembly includes a pivot rod on which the rotary gate is adapted to rotate and a cam having a continuous cam surface with a plurality of lobes disposed at spaced intervals therealong for defining a plurality of rotary gate home positions with the cam being operatively secured to the pivot rod. A first member, which can be a ball or a rod, is cooperatively positioned relative to the cam surface for selectively allowing a rotationaly movement of the cam generally for an angular extent at least equal to an angle defined between adjacent ones of the lobes. Preferably, a second such member is also cooperatively positioned relative to the cam surface for the same purpose. The second member is spaced from the first member.
