ABSTRACT:
A chuck includes a support and a plurality of pairs of oppositely disposed jaws with the jaws being movable to a position with each pair of jaws disposed on diametrically opposite sides of one element of an assembly. A motor moves selected pairs of the jaws into contact with the element and an additional motor moves the selected pairs of jaws and element away from the support to extract the element while at least one of the pairs of oppositely disposed jaws are maintained in position on the support to secure a second element of the assembly against movement while the selected pairs of jaws extract the one element.
