ABSTRACT:
Bricks are continuously received in double-layer courses, which courses are shifted one at a time onto a receiving plate whereupon a gripper apparatus is activated to grip the opposite sides of the course and retain the course as the receiving plate is removed from beneath the course. A platform is elevated to engage or cause the bricks already deposited thereon to engage the lower surface of the course being held by the gripper apparatus whereupon the gripper apparatus is deactivated. The elevator lowers and the receiving plate is returned to its initial position. During selected course transfers a tyne tray apparatus cooperates with the gripper apparatus to form tyne openings in selected layers. The gripping apparatus itself includes a first set of longer outer gripper plates which are adapted to grip entire courses at times and a plurality of shorter, inner grippers which cooperate with the outer gripper plates or with other inner grippers to grip partial courses after the tyne bricks have been removed.
