ABSTRACT:
An actuator member is disclosed in which the actuator member is capable of providing linear and selective rotary movement of the table top of the conveyor member. The actuator member includes a platform housing which can be fixedly attached to conventional conveyor links in a conveyor line, or linear slides. A follower wheel is rotably mounted in the platform housing and includes a table top. The follower wheel is provided with an actuation mechanism for engaging a stationary cam and selectively preventing rotation of the table top or rotating the table top a predetermined radial distance as the conveyor member progresses down the conveyor line. The stationary cam includes dwell portions and index portions which are selectively placed so that, when the actuation mechanism engages the dwell portions, the rotatable table top is not rotated and, when the actuation mechanism engages the index portions, the table top is rotated a predetermined radial distance such as 90.degree., 180.degree. or some other amount. The inventive actuator member can be used on standard conveyor links and conveyor assemblies or can be used in linear slide mechanisms to provide linear and selective rotary movement of the table top.
