  • Patent number: 4161368
    Abstract: Apparatus for selectively blending rows of bricks includes a blending station having a blending area into which bricks are introduced from first and second staging areas on opposite sides of the blending area. In a preferred embodiment, the bricks are delivered by conveyors to the staging areas in spaced parallel rows. Brick transfer means are provided for each brick row in each staging area and may be selectively actuated to transfer rows of bricks into the blending area in the desired blend, the rows being moved longitudinally so as to interleave with the rows from the opposite staging area. Retractable guide means are provided to prevent interference between the oppositely moving rows of bricks. Upon retraction of the guide means, a conveyor moves the bricks from the blending area to permit the repetition of the blending operation.
