Abstract: Each row of uncured brick is arranged with a longitudinal axis extending transversely across the width of a push-off table and is serially pushed by preceding rows past the end of the table. An elevator device registers a first platform with the end of the push-off table to receive a first row(s) and a second platform vertically spaced therefrom to receive a second row(s). The upper and lower row(s) are then simultaneously pushed from the elevator onto the upstream end of a marshalling table to form a two layer stack. A first shuttle device includes a plurality of shorter, longitudinally extending bars interspersed between the bars forming the marshalling table. The bars of the shuttle device are vertically movable between a first position beneath the level of the marshalling table bars, and a second position above such level supporting the bricks thereon.

Abstract: An improved gripper member for airbag setters formed by a pair of perforated plate members depending from an air manifold and separated at the top, then preferably converging and secured together at the bottom. A sheet of air impervious flexible material is attached at the bottom between an attachment strip and a corresponding surface of one of the plates, then wraps up over the attachment strip and is secured along the upper edge to form an airbag on one side of the perforated plate members. A second sheet of air impervious flexible material is similarly fastened to the other side of the perforated plate.
