ABSTRACT:
The invention relates to an apparatus for converting a unidirectional displacement to an angular displacement of selectable direction. The apparatus 10 has a rack gear assembly, which has two opposing rack gears 16 and 17 held in a parallel spaced relationship and constituting a coordinate plane. Disposed within the two opposing rack gears is rotational shaft 15 having attached to it engagement pin 21 for engaging a segmental pinion gear slot 22 or 23. A pair of opposing segmental pinion gears 13 and 14 are rotatably attached to shaft 15. Each segmental pinion gear 13 and 14 is engaged with a corresponding rack gear 16 and 17. The invention also provides a means for engaging the first said engagement means with either one of the two segmental pinion gears.
