A material handling device for moving work pieces successively between adjacent work stations. The device includes a plurality of grippers, each supported on a common member. Each gripper is operative between a gripping position for gripping a work piece and a released position for depositing the work piece. A motion transfer device is incorporated for moving the grippers and their supporting member from a home position to a position where the grippers are each juxtaposed to a work station whereby the work piece in that station may be grasped. Once the work pieces are gripped, the motion transfer device moves the grippers and the supporting member to another position wherein each work piece will be positioned at to the next adjacent work station. The grippers are then released so that the work piece will be deposited and the grippers and their supporting member are returned to the home position.
