ABSTRACT:
A first member defines a plurality of depressions such as V-shaped notches therein and is positioned so that the V-shaped notches are adjacent another plurality of similar notches defined by a second member. The spacing of the recesses in the second member is different than the spacing of recesses in the first member. A movable ball is received in each of the recesses of the first member. A cam is positioned to alternately force one of the balls into engagement between partially aligned recesses on the first and second members forcing relative movement between the members, positioning a load connected thereto.
