Description: Apparatus in which there are two or more workholders or supports which are supported so that the weight of one and work therein would be partly or wholly counterbalanced or counterpoised by the weight of at least one of the others and work therein. This includes, for example, the two types (1) in which two workholders are supported on a walking beam at opposite sides of the supporting pivot of the beam so that one workholder moves up when the other moves down, and (2) two workholders which are supported by and on opposite sides of a movable column, but in which the two workholders are not necessarily arranged to move one upwardly when the other moves downwardly, but both may move up simultaneously or down similarly.
