Abstract
A device for limiting the rotation of a member rotatable about an axis extending from a base, while permitting rotation clockwise and counterclockwise through a preselected number of turns. An actuating lug is rigidly secured to the member, a disc is rotatably secured to the base, the disc having a plurality of bosses rigidly secured adjacent the periphery thereof, the bosses being spaced apart from each other in equal angular relationship, the bosses being engaged by the actuating lug to cause angular displacement of the disc upon each rotation of the member. A stop lug is rigidly secured to the base in the path of the disc bosses to engage therewith and arrest angular displacement of the disc and thereby the rotation of the member.
