ABSTRACT:
A mechanical stop permitting rotation of more than one revolution, but less than two revolutions. A wheel having a pin attached is rotated about an axis. A pair of pivoting flip-flops each having two perpendicular legs is placed in the path of the pin. The pin, after passing each flip-flop, flips the flip-flop into a stop position from an initial pass position. This permits the pin to pass each flip-flop only once during rotation in one continuous direction. The flip-flop spacing determines the distance beyond one revolution the wheel is permitted to travel. The flip-flops reset each time the wheel reverses direction.
