ABSTRACT:
A conveying apparatus for conveying work pieces along a path defined by a track that can have ascending and descending sections. An elevator mechanism is pivotally supported relative to a drive mechanism that cooperates with the track for moving work pieces from one place to another. The pivotal support of the elevator mechanism permits the articles being transported to be maintained in a horizontal position regardless of whether or not the device is ascending or descending. In addition, a shock absorbing mechanism acts upon the pivotal connection so as to avoid swinging movement caused by starting and stopping.
