Abstract
A carrier is mounted for movement along a conveying path defined by a pair of conveying rails, one of which has a relatively short gap at a work station. A manipulator device is located at the work station and includes a relatively short conveying rail section which may selectively located to span the gap in the one rail or located in a position displaced from the rail. An article support frame is mounted upon the carrier for pivotal movement about an axis parallel to the rails between conveying position and a transfer position. A rail gripping device fixed to the support frame slides along the one rail to support the support frame in its conveying position during movement of the carrier along the rails. When the carrier arrives at the work station, the gripping device engages the short rail section of the manipulator which is then actuated to displace the rail section from the rail to pivot the support frame to its transfer position in which an article supported on the support frame may be processed by tooling located at the work station.
