A flipper assembly has a flipper plate and an aligned guide rail both of which provide a support surface for a movable assembly. The flipper plate is movable into and out of the plane of the support surface. An extension arm is mounted on the guide rail for movement in a horizontal plane thereon and for movement in a vertical direction at the location of the flipper plate if permitted by the position of the flipper plate. The flipper plate is counterbalanced to an open position permitting the carrier arm to be moved vertically at that location, but is automatically positioned in a down closed position supporting the carrier arm in the plane of the guide rail support, by an automatic camming action as the slide arm moves toward and onto the flipper plate. In the preferred embodiment, the flipper plate safety device is utilized in a multistation work processing conveyor apparatus and is mounted on a vertical elevator.
