  • Patent number: 6205742
    Abstract: A method and apparatus for manufacturing and installing a roof structure, in which clay is formed into tiles which simulate wood shakes, and the tiles are attached atop a supporting surface in a predetermined manner in a substantially unrecognizable pattern. The tile configuration provides a structure which is light in weight yet is structurally sound, which lends itself to ready installation upon a wide variety of structures.

  • Patent number: 5993551
    Abstract: A clay tile or other formed item having a simulated appearance and a method and apparatus for providing same includes the use of perceptibly random spray patterns and multiple spray nozzles to dispense a coating liquid upon the item prior to its drying and possible firing. Upon drying, the tiles processed thereby include improved appearance characteristics. Spraying is accomplished by a computer controlled spray system which includes, in one embodiment, multiple banks of spray guns (as an example, three guns per bank) which spray liquid upon clay tiles or other items passing thereunder. The spray guns can oscillate sidewardly relative to the general path of the moving items, to further enhance the perceptibly random spray patterns. Different types of engobe or other coatings may be sprayed by each of the banks of spray guns. The method and apparatus can also be used in association with the coloration of clay brick, concrete roof tiles, concrete brick, and concrete block.
