  • Patent number: 4229156
    Abstract: 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.

  • Patent number: 4178340
    Abstract: The method and apparatus for making concrete brick in a manner such that at least both elongated sides of the brick have an antique appearance. In the method for making the concrete brick, coloring material is spread on a pallet after which a plurality of concrete bricks are molded with their side faces engaging the material on the pallet. The moisture in the bricks wets the material and causes such material to adhere to the bricks, such coloring material imparting a mottled effect to the brick. Additional coloring material is applied to the uppermost side of the bricks and is smeared or streaked by a brush or roller. Thereafter the pallet is moved to another area where the bricks are cured and stored.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.
