DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIGS. 1A to 1C, base block 10 has a series of regularly-spaced identical perforations 11 (only one labeled) extending entirely through the base block from one side to the opposed side. The perforations have circular cross-sections. The series of perforations is arranged in a straight line A-A, along which the base block may be split by a light shock. On splitting the base block, two virtually identical standard building blocks 16,17 are produced, having textured faces 18,19, respectively. The textured faces have a consistent and reproducible uniform striated appearance as a result of the arrangement of regularly-spaced identical perforations in the base block.


Referring to FIGS. 2A to 2C, base block 20 has a series of two types of regularly-spaced perforations 21,22 (only one of each type labeled) extending entirely through the base block from one side to the opposed side. Both types of perforations have circular cross-sections, although perforations 21 have a smaller diameter than perforations 22. The series of perforations is arranged in a straight line, along which the base block may be split by a light shock. On splitting the base block, two virtually identical standard building blocks 26,27 are produced, having textured faces 28,29, respectively. The textured faces have a consistent and reproducible regular striated appearance as a result of the arrangement of regularly-spaced perforations in the base block. The textured faces have alternating shallow and deep sections as a result of the difference in diameter of the two types of perforations.


Referring to FIGS. 3A to 3C, base block 30 has a series of irregularly-spaced perforations 31 (only one labeled) of widely differing cross-sectional shapes extending entirely through the base block from one side to the opposed side. The series of perforations is arranged in a straight line, along which the base block may be split by a light shock. On splitting the base block, two virtually identical standard building blocks 36,37 are produced, having textured faces 38,39, respectively. The textured faces have a consistent and reproducible, but random, striated appearance as a result of the arrangement of irregularly-spaced perforations in the base block. Although the textured faces have a random appearance, each block has the same appearance and the appearance can be consistently reproduced in other building blocks.


Referring to FIGS. 4A to 4C, base block 40 has a series of two types of regularly-spaced perforations 41,42 (only one of each type labeled) extending entirely through the base block from one side to the opposed side. One type of perforation 41 has circular cross-sections, and the other type 42 has a rounded rectangular cross-sections. The series of perforations is arranged in a straight line, along which the base block may be split by a light shock. On splitting the base block, two virtually identical standard building blocks 46,47 are produced, having textured faces 48,49, respectively. The textured faces have a consistent and reproducible regular striated appearance as a result of the arrangement of regularly-spaced perforations in the base block. The textured faces have narrow sections as a result of perforations 41 and wide sections as a result of perforations 42.


Referring to FIGS. 5A and 5B, base block 50 has a series of regularly-spaced identical perforations 51 (only one labeled) extending entirely through the base block from one side to the opposed side. The perforations have circular cross-sections and are arranged in a manner similar to FIG. 1A. Thus, the series of perforations is arranged in a straight line, along which the base block may be split by a light shock. One half of the base block is designed to be a 3-hole brick and the other half a recess (frog) brick. On splitting the base block, 3-hole brick 56 and frog brick 57 are formed having identical textured faces 58,59 respectively. The textured faces have a consistent and reproducible uniform striated appearance as a result of the arrangement of regularly-spaced identical perforations in the base block.


Referring to FIGS. 6A to 6C, base block 60 has a series of regularly-spaced identical perforations 61 (only one labeled) extending entirely through the base block from one side to the opposed side. The perforations have circular cross-sections with a diameter of 0.25 inches. The series of perforations is arranged in a straight line along which the base block may be split by a light shock. On splitting the base block, two virtually identical skid resistant paving stones 66,67 are produced, having textured faces 68,69, respectively. The textured faces have a consistent and reproducible uniform striated appearance as a result of the arrangement of regularly-spaced identical perforations in the base block. FIG. 6C illustrates paving stones 66,67 in place together with a third paving stone 65 produced in a similar manner.


Referring to FIGS. 7A and 7B, base block 70 has a series of two types of regularly-spaced perforations 71,72 (only one of each type labeled) extending entirely through the base block from one side to the opposed side. Both types of perforations have circular cross-sections, although perforations 71 have a smaller diameter than perforations 72. The series of perforations is arranged in an arc B-B, along which the base block may be split by a light shock. On splitting the base block, two building blocks 76,77 are produced, having textured faces 78,79, respectively. The textured faces have consistent and reproducible regular striated appearances as a result of the arrangement of regularly-spaced perforations in the base block. The textured faces have alternating shallow and deep sections as a result of the difference in diameter of the two types of perforations. Textured face 78 is convex while textured face 79 is concave. When laid side-by-side as illustrated in FIG. 7B, the textured faces of blocks 76,77 create an undulating appearance. Since many such blocks may be reproduced consistently, a course of such blocks can provide a block wall having a consistent undulating appearance.


Referring to FIGS. 8A to 8C, base block 80 has four series of two types of regularly-spaced perforations 81,82 (only one of each type labeled) extending entirely through the base block from one side to the opposed side. Both types of perforations have circular cross-sections, although perforations 81 have a smaller diameter than perforations 82. Each of the four series of perforations is arranged in an arc, along which the base block may be split by a light shock. On splitting the base block, three building blocks 85,86,87 and six scrap pieces 84 are produced. Each building block is double-sided having a concave textured face 88 (only one labeled) and an opposed convex textured face 89 (only one labeled). The textured faces have consistent and reproducible regular striated appearances as a result of the arrangement of regularly-spaced perforations in the base block. The textured faces have alternating shallow and deep sections as a result of the difference in diameter of the two types of perforations. A plurality of such building blocks laid side-by-side can provide a curved block wall having a consistent appearance.


Referring to FIGS. 9A to 9C, base block 90 has two series of regularly-spaced perforations 91 (only two labeled) extending entirely through the base block from one side to the opposed side. One series of perforations starts at a first edge of the base block and is arranged in a straight line about halfway to an opposed edge of the base block. The other series of perforations starts at the opposed edge of the base block and is arranged in a straight line about halfway to the first edge. The two series of perforations are parallel to each other but are set apart by a distance. Spanning the distance between the two series of perforations is a single rectangular perforation 92 with rounded ends that is oriented perpendicular to the two series of perforations. Thus, a Z-shaped splitting path is created in the base block. On splitting the base block, two identical step blocks 96,97 are produced, each step block having two uniformly textured surfaces 98,99. As illustrated in FIG. 9C, when laid side-by-side with a third step block 95 produced in a similar manner, the step blocks provide skid-resistant stairs. Each step block is formed with cavities 94 to reduce the weight of the step blocks.


Referring to FIGS. 10A to 10C, base block 100 has a series of regularly-spaced identical perforations 101 (only one labeled) extending entirely through the base block from one side to the opposed side. The perforations have circular cross-sections. The series of perforations is arranged in a straight line along which the base block may be split by a light shock. The series of perforations is located within recess 102. On splitting the base block, two virtually identical standard building blocks 106,107 are produced, having textured faces 108,109, respectively, with joint set backs 104,105 respectively. The textured faces have a consistent and reproducible uniform striated appearance as a result of the arrangement of regularly-spaced identical perforations in the base block. The textured faces have joint set backs as a result of the recess in the base block.


Referring to FIGS. 11A to 11C, base block 110 has a series of irregularly-spaced perforations 111 (only one labeled) of widely differing cross-sectional shapes extending entirely through the base block from one side to the opposed side. The series of perforations is arranged in a straight line along which the base block may be split by a light shock. The series of perforations is located within recess 112. On splitting the base block, two virtually identical light shell blocks 116,117 are produced, having textured faces 118,119, respectively, with joint set backs 114,115 respectively. The textured faces have a consistent and reproducible, but random, striated appearance as a result of the arrangement of irregularly-spaced perforations in the base block. The textured faces have joint set backs as a result of the recess in the base block.


Referring to FIGS. 12A to 12C, base block 120 has five series of regularly-spaced identical perforations 121 (only one labeled) extending entirely through the base block from one side to the opposed side. The perforations have circular cross-sections. Each of the five series of perforations is arranged in a straight line, along which the base block may be split by a light shock. The five series of perforations are parallel to each and spaced apart equidistantly. On splitting the base block, four virtually identical double-sided standard building blocks 126 (only one shown) and two virtually identical single-sided standard building blocks 127 (only one shown) are produced. Textured faces 128,129 of the double-sided block and textured face 125 of the single-sided block are virtually identical in appearance. The textured faces have a consistent and reproducible uniform striated appearance as a result of the arrangement of regularly-spaced identical perforations in the base block. Any number of double-sided blocks may be created from a single base block by having more or fewer series of perforations.


Referring to FIGS. 13A to 13C, base block 130 has five parallel series of two types of regularly-spaced perforations 131,132 (only one of each type labeled) and one series of two types of regularly-spaced perforations 131,132 (only one of each type labeled) perpendicular to and bisecting the five parallel series. All perforations extend entirely through the base block from one side to the opposed side. One type of perforation 131 has circular cross-sections, and the other type 132 has a rounded rectangular cross-sections. Each of the six series of perforations is arranged in a straight line, along which the base block may be split by a light shock. On splitting the base block, eight virtually identical triple-sided standard building blocks 136 (only one shown) and four virtually identical double-sided standard building blocks 137 (only one shown) are produced. Textured faces 138,139 of the double-sided block are perpendicular to each other, one being a long face and the other a short face. The triple-sided block has two long textured faces 133,134 and one short textured face 135. The textured faces have a consistent and reproducible regular striated appearance as a result of the arrangement of regularly-spaced perforations in the base block. The textured faces have narrow sections as a result of perforations 131 and wide sections as a result of perforations 132.


Referring to FIGS. 14A to 14C, base block 140 is cross-shaped and has four series of irregularly-spaced perforations 141 (only one labeled) of widely differing cross-sectional shapes extending entirely through the base block from one side to the opposed side and meeting at a single large perforation 142 in the center of the base block. Each of the four series of perforations is arranged in a straight line, along which the base block may be split by a light shock. On splitting the base block, four virtually identical corner blocks 144,145,146,147 are produced, each having two textured faces, a long face 148 (only one labeled) and a short face 149 (only one labeled). The textured faces have a consistent and reproducible, but random, striated appearance as a result of the arrangement of irregularly-spaced perforations in the base block. Although the textured faces have a random appearance, each block has the same appearance and the appearance can be consistently reproduced in other building blocks. The two textured faces 148,149 are perpendicular to each other, suitable for a corner block in block wall construction.


Referring to FIGS. 15A to 15C, base block 150 is cross-shaped and has four series of irregularly-spaced perforations 151 (only one labeled) of widely differing cross-sectional shapes extending entirely through the base block from one side to the opposed side. Each of the four series of perforations is arranged in a straight line, along which the base block may be split by a light shock. Each of the four series of perforations is within recess 152 of the base block. On splitting the base block, four virtually identical light shell corner blocks 154,155,156,157 are produced, each having two textured faces, a long face 158 (only one labeled) and a short face 159 (only one labeled), and joint set back 153 (only one labeled). The textured faces have a consistent and reproducible, but random, striated appearance as a result of the arrangement of irregularly-spaced perforations in the base block. The textured faces have joint set backs as a result of the recess in the base block.
