An apparatus for making concrete brick in a manner such that at least both elongated sides of the brick have an antique appearance. In the apparatus a first hopper is provided which discharges coloring material onto an empty pallet that passes below the same. The pallet is moved into a concrete brick-making machine where a plurality of bricks are formed on their sides with the lowermost side in engagement with the coloring material. Thereafter a second hopper discharges coloring material onto the upper side of the bricks and such coloring material on the top is spread lengthwise. The forming of the bricks on the coloring material on the pallet provides a mottled effect on one side of the brick and the spreading of the coloring material provides a streaked effect on the other side so that a different antique appearance is imparted to opposite sides of the brick.
In an apparatus for making bricks which includes a molding means having a mold and supply of liquefied hardenable material, the improvement comprising inlet and outlet conveyor means associated with said molding means, at least one pallet carried by said conveyor means, a first hopper located adjacent to said inlet conveyor means and containing a first supply of flowable coloring material, first dispensing means for selectively discharging coloring material from said first hopper onto said pallet as said inlet conveyor means moves said pallet past said first hopper, said brick making apparatus including a mold and means to position said mold in engagement with said pallet to mold at least one brick on said pallet with one side of said brick engaging said coloring material and means to remove said mold from said pallet, a second hopper located adjacent to said outlet conveyor means and containing a second supply of flowable coloring material, second dispensing means for selectively discharging coloring material from said second hopper onto the opposite side of said brick carried by said pallet, and means for saturating said second coloring material on said brick, whereby coloring material is applied substantially to opposite sides only of said brick.
