Abstract
A linear motion device of the type having a plurality of gripper assemblies for engaging projections on a linearly movable element to effect stepwise movement thereof. Each of the gripper assemblies is movable into and out of engageable relationship with the element to thereby yield three relative positions between the element and the gripper assembly--a latched position, a coupled position and an unlatched position. Also, each of the gripper assemblies is movable relative to its support means between respective raised and lowered positions. The gripper assemblies are supported on the support means in spaced relationship and the projections are spacedly positioned on the element so that each gripper assembly, when in its lowered position relative to the support means, can be moved into the coupled position with respect to the element when the other gripper assembly is in its latched position and is in either its raised position or lowered position relative to the support means.
