Abstract
A continuously movable conveyor supports a plurality of articles for movement along a path leading to and beyond a zone at which selected articles are transferred from and returned to the conveyor. At the transfer zone is stop apparatus movable from a position clear of the path of movement of the articles on the conveyor to a position in which it projects into such path of movement so as to engage and stop an oncoming article as the conveyor continues to move. The stop apparatus includes a stop member supported by a parallelogram linkage which is rockable by an extensible and retractable hydraulic ram to effect movements of the stop member into and out of the path of conveyor borne articles. The coupling of the ram to the stop member includes a lost motion connection enabling displacement of the stop member upon engagement of the latter by an article on the conveyor and the ram is yieldably retractable in response to such engagement so as to absorb and cushion the shock of such engagement. Following stopping of the article on the conveyor the ram returns to its extended position and locates the stop member in such position that, upon retraction of the ram to move the stop member out of the path of movement of conveyor borne articles, the stop member has a component of movement along the conveyor path so as to avoid the imposition of binding forces on the stop member by the article engaged thereby.
