`SIDE-SPLIT BLOCK THEREFORE
Background _f the Invention The invention relates to a primary masonry type block formed from concrete and a method of manufacture thereof and a masonry wall cons~ructed of a plurality of blocks laid up in courses and a method of constructing the same.
Various building type blocks have been made from cement-like material such as concrete or similar material to be used in constructing walls or the like. Many of such blocks have been constructed for strength and heat insulating purposes. Further, many building type blocks have been irregularly shaped and/or colored to provide a decorative ap-pearance. In some constructions, two or more blocks ; have been molded as an integral unit and ;thereafter split to provid2 an outer surface~ having a rough irregular type decorative outward appearance.
`~ ~ 20 Brief Summary of the Invention A primary masonry ty;pe block formed from concrete provides a front surface including a first surEace area having a distinct irregular split-type decorative appearance which includes a portion space from a reference plane provided by a back wall sur-l~ ~ face by a first predetermined depth. The front ¦ surface further includes a second sur~ace area hav-ing a distinct irregular split-type decorative appearance which includes a portion space from the reference plane by a second predete~mined depth which is substantially different than the first depth. In such manner, the primary masonr~ type block provides a plurality of distinct irregular split type surface areas of varying depths for a decorative appearance.
~ '.
3~5 The first front surface area is formed with a first predetermined width while the second surface area is formed with a second predetermined width substantially different than the first width. In such manner, the primary masonry type block provides a front surface having a plurality of dis~inct irregular split-type surface areas of vary-ing widths for a decorative appearance.
Two building type blocks are simultaneous-ly formed. A mold is formed which provides oppo-sitely spaced first and second back walls and oppo-sitely spaced first and second side walls to provide a cavity therebetween. A projection is placed in the cavity to be spaced from the first and second back walls to define two block shaped compartments and further define first and second substantially parallel splitting planes which intersect the pro-jection and the first and second side walls. A
composite module is form~d b~ placing cement-like material into the mold and removing the projection so that the cured material includes two integrally joined blocks. The composite module is split along selected portions of the first and second splitting planes to form the first and second blocks each providing first and second front surface portions of different depths with respect to the corresponding first and second back walls for a decorative appear-ance.
First and second ridges are formed on the projection so as to be within the first and second splitting planes, respectively. In such manner, the ridges form first and second guides to facilitate the splitting of the composite module. First and second ridges are also placed on the first and second side walls, respectively, to be within the first and second splitting planes, respectively. In such manner, the ridges form first and second guides to facilitate the splitting of the composite module.
The projection is placed in the mold at a first predetermined distance from the first side 5 wall and a second predetermined distance different than the first distance from the second side wall.
When the composite module is split~ a first front surface portion is provided of a first predetermined width while the second front surEace portion is provided with a second predetermined width different from the first width.
A pair of projections or prongs are pro-vided by a division member where the first prong is placed at a first predetermined distance from the side wall of the mold and the second prong is placed at a second predetermined distance from a second oppositely spaced side wall~of the mold to divide each compartment into first, second and third sec-tions which are spaced by irst, second and third predetermined depths, respectively, from a first back wall and spaced by fourth, fifth and s~ixth predetermined depths, respectively, from a second back wall oppositely spaced from the first back wall.
The composite module is engaged by first, second, third and fourth pairs of oppositely dis~
posed splitting ~nives with the first pair of knives engaging one of the openings formed by the division member prongs to form first and fourth front wall split surface portions of the first and second blocks respectively. The second pair of knives engages one of the openings to form second and fifth front wall split surface portions of the first and second bJ.ocks respectively. The third pair of knives engages one of the openings to form third and sixth front wall split surface portions of the first 6~
and second blocks respectively. The fourth pair of knives engage oppositely spaced side walls of the composite module. One of the fourth knives is aligned with the first knives to assist in forming the first and fourth split surface portions.
Another of the fourth knives is aligned with the third knives to assist in forming the third and sixth split surface portions. In such ~anner, the composite module is split to provide first and second blocks with the first block providing first, second and third split type surface portions of irregular and decorative appearance including first, second and third different depths, respectively, and first, second and third different widths, respec-tively. The second block, on the other hand,provides fourth! fifth and sixth split type- surface ; portions of irregular and decorative appearance having fourth, fifth and sixth dif~erent depths, ; respectively, and fourth, fifth and sixth widths, respectively.
When using a division member with two prongs, a first ridge is provided on the first prong and is aligned with a second ridge placed on the first side wall to ~orm a first splitting pIane. A
third ridge is placed on the first prong while a fourth ridge is placed on the second prong to be aligned within a second splitting plane which is spaced from the first splitting plane. A fifth ridge is placed on a second prong and aligned with a sixth ridge placed on a second side wall to be with in a third splittin~ plane which is spaced from the irst and second splitting planes.
A masonry wall is constructed of a plural-ity of blocks laid up in courses with mortared joints therebetween wherein each of the blocks provides a back surface and oppositely spaced front .. . .. . ..
surface. The front surface includes a first surface area having a distinct irregular split type decora-tive appearance including a portion spaced by a first predetermined depth from a reference plane provided by the back surface and a second surface area having a distinct irregular split type decora-tive appearance including a portion spaced by a second predetermined depth different from the first depth from the reference plane. First and second surface areas in one course are spaced out of verti-cal alignment with first and second surface areas in another immediately adjacent course to provide a wall having a plurality of adjacent surface portion areas of random]y different depths for a decorative appearance~
With the front surface of each block including a first surface area having a distinet irregular split type decorative appearance having a first predetermined width and a`second surface area having a distinct irregular split type decorative ~; appearance having a second predetermined width dif-ferent than the first width, the first and second surfaee areas in one course are spaced out of verti-eal alignment with the first and second surfa~e

3~5 The first front surface area is formed with a first predetermined width while the second surface area is formed with a second predetermined width substantially different than the first width. In such manner, the primary masonry type block provides a front surface having a plurality of dis~inct irregular split-type surface areas of vary-ing widths for a decorative appearance.
Two building type blocks are simultaneous-ly formed. A mold is formed which provides oppo-sitely spaced first and second back walls and oppo-sitely spaced first and second side walls to provide a cavity therebetween. A projection is placed in the cavity to be spaced from the first and second back walls to define two block shaped compartments and further define first and second substantially parallel splitting planes which intersect the pro-jection and the first and second side walls. A
composite module is form~d b~ placing cement-like material into the mold and removing the projection so that the cured material includes two integrally joined blocks. The composite module is split along selected portions of the first and second splitting planes to form the first and second blocks each providing first and second front surface portions of different depths with respect to the corresponding first and second back walls for a decorative appear-ance.
First and second ridges are formed on the projection so as to be within the first and second splitting planes, respectively. In such manner, the ridges form first and second guides to facilitate the splitting of the composite module. First and second ridges are also placed on the first and second side walls, respectively, to be within the first and second splitting planes, respectively. In such manner, the ridges form first and second guides to facilitate the splitting of the composite module.
The projection is placed in the mold at a first predetermined distance from the first side 5 wall and a second predetermined distance different than the first distance from the second side wall.
When the composite module is split~ a first front surface portion is provided of a first predetermined width while the second front surEace portion is provided with a second predetermined width different from the first width.
A pair of projections or prongs are pro-vided by a division member where the first prong is placed at a first predetermined distance from the side wall of the mold and the second prong is placed at a second predetermined distance from a second oppositely spaced side wall~of the mold to divide each compartment into first, second and third sec-tions which are spaced by irst, second and third predetermined depths, respectively, from a first back wall and spaced by fourth, fifth and s~ixth predetermined depths, respectively, from a second back wall oppositely spaced from the first back wall.
The composite module is engaged by first, second, third and fourth pairs of oppositely dis~

The second pair of knives engages one of the openings to form second and fifth front wall split surface portions of the first and second bJ.ocks respectively. The third pair of knives engages one of the openings to form third and sixth front wall split surface portions of the first 6~
and second blocks respectively. The fourth pair of knives engage oppositely spaced side walls of the composite module. One of the fourth knives is aligned with the first knives to assist in forming the first and fourth split surface portions.
Another of the fourth knives is aligned with the third knives to assist in forming the third and sixth split surface portions. In such ~anner, the composite module is split to provide first and second blocks with the first block providing first, second and third split type surface portions of irregular and decorative appearance including first, second and third different depths, respectively, and first, second and third different widths, respec-tively. The second block, on the other hand,provides fourth! fifth and sixth split type- surface ; portions of irregular and decorative appearance having fourth, fifth and sixth dif~erent depths, ; respectively, and fourth, fifth and sixth widths, respectively.
When using a division member with two prongs, a first ridge is provided on the first prong and is aligned with a second ridge placed on the first side wall to ~orm a first splitting pIane. A
third ridge is placed on the first prong while a fourth ridge is placed on the second prong to be aligned within a second splitting plane which is spaced from the first splitting plane. A fifth ridge is placed on a second prong and aligned with a sixth ridge placed on a second side wall to be with in a third splittin~ plane which is spaced from the irst and second splitting planes.

surface. The front surface includes a first surface area having a distinct irregular split type decora-tive appearance including a portion spaced by a first predetermined depth from a reference plane provided by the back surface and a second surface area having a distinct irregular split type decora-tive appearance including a portion spaced by a second predetermined depth different from the first depth from the reference plane. First and second surface areas in one course are spaced out of verti-cal alignment with first and second surface areas in another immediately adjacent course to provide a wall having a plurality of adjacent surface portion areas of random]y different depths for a decorative appearance~
With the front surface of each block including a first surface area having a distinet irregular split type decorative appearance having a first predetermined width and a`second surface area having a distinct irregular split type decorative ~; appearance having a second predetermined width dif-ferent than the first width, the first and second surfaee areas in one course are spaced out of verti-eal alignment with the first and second surfa~e
2$ areas in another immediate1y adjacent eourse to provide a wall having a plurality of adjacent surface portions of randomly diferent widths for a decorative appearance.
A masonry wall may be formed of a plural-ity of first and second blocks formed from a singlemolded construction and laid up in courses with mortared joints therebetween. The first blocks used in such wall inelude a front wall surface including first, second and third distinct surface areas each at a different depth with respect to the block back surfaee and each haviny a different width. The second blocks used in such wall include fourth, ~ifth and sixth distinct surface areas each spaced ~rom the back wall portion by a different depth and each having a different width. In the wall, the first and sixth surace portions are located immediatel~ adja-cent to each other while the third and fourth surface portions are located immediately adjacent to each other within each course.
The first through sixth portions in one course are spaced out of vertical alignment with the first through sixth portions in an-other immediately adjacent course to provide a wall having a plur-10 alit~ of adjacent surface portions of randomly different widths and depths for a decorative appearance.
The blocks and manufacture thereof have been found to provide an extremely decorative appearance particularly when for-med in a wall configuration and are economical to manufacture.

The ridges 98 and 99 are spaced from the mold box endwall 67 by a predetermined distance 32 and are spaced from the mold box endwall 68 by a predetermined distance 55.
After the prongs 81 and 82 of divider 80 are placed within the mold box 65, cement-like material such as concrete or the like is placed within the cavity 74 and permitted to harden to form a unitary composite 1~. Either while the cement-like material is hardening or after it has hardened and cured, the division plate 80 and the retaining 15 bars 76 and 78 and associated form members 75, 77 and 79 are removed thereby leaving a unitary compos-ite 14 as illustrated in Fig. 3. The cement-like material may be placed into a kiln for steam curing for hardening the concrete.
The composite 14 includes a vertically extending notch 101 which has been formed by the ridge 92 and defines a separation between the side-walls 15 and 42. Further, an oppositely spaced vertically extending notch 102 has been formed by ridge 99 and forms a separation between the side-walls 16 and 43. A pair of openings 103 and 104 have been formed in the central portion o the com posite 14 by the removal of the prongs 81 and 82, respectively. The opening 103 includes the oppo-sitely spaced grooves 33 and 59 while the opening104 includes the oppositely spaced grooves 36 and 61~ A vertically extending notch 105 of opening 103 is ~ormed by the ridge 91 and is aligned with notch 101 to be within a common plane 2~, 51. The opening 103 further provides a vertically extending notch 106 which has been formed by ridge 93 and is aligned with a notch 107 of opening 104 to be within a common plane 33, 56. A vertically extending notch 108 of opening 104 is aligned with notch 102 to be within a common plane 31, 54.
Following the removal from the molding box 65, the composite 14 progresses along a conveyer 109 to a splitting apparatus 110. The splitter 110 may be selected from any one o a number of known commercial cement block splitting machines, such as marketed by Columbia Machine, Inc. of Vancouver, Washington, but modified to have plural cutting blades as more fully set forth hereafter. As the composite 14 reaches a predetermined point, limit ; switches or other sensing devices activate a series of arms 111 which operate to transfer composite 14 into a splitting chamber 112 provided by the splitting machine 110. The splitting machine 110 includes a base member 113 which retains a series of splitting blades as illustrated at 114, 115 and 116.
` 20 The base or bed ]13 is supported by a series of supports 117 which, in turn, ~urther support a series of upwardly directed threaded rods 118. An upper carriage 119 is mounted upon rods 118 and is selectively activated to move vertically. A
plate assembly 120 is mounted on a lower portion oE
carriage 119 and includes three spaced splitting blades 121, 122 and 123 which are aligned with associated splitting blades 114, 115 and 116 mounted therebelow~ In such manner, the pair of splitting blades 114 and 121 are mounted within the same splitting plane and are designed to be aligned with the module 14 along the splittiny plane 28, 51. In like manner, the pair of splitting blades llS and 122 are aligned within the same plane and are designed to be aligned with the splitting plane 33, 56 of module 14. The pair of blades 116 and 123 are ~ ~6`~32~
likewise aligned within the same plane and are designed to be aligned with the splitting plane 31, 54 of the module 14.
A pair of spaced reciprocating pistons 124 and 125 are located on opposite sides of the chamber 112 and attached to one or more of the rods 118.
The reciprocating piston 124 provides a splitting blade 126 which is adapted to be aligned with notch 101 of module 14 which corresponds to the plane 28, 51. The reciprocating piston 125 also includes a splitting blade 127 which is situated to be aligned with notch 102 of module 14 and therefore ali~ned with the plane 31, 54.
The splitting apparatus 110 senses the relative positioning of the module 14 within the chamber 112 such as through an appropriate sensor to operate the carriage 119 to vertically move the splitting blades 121, 122 and 123 in a downward direction to strike the top oE~module 14. Simulta-neously, the pistons 124 and 125 are operated to move the splitting blades 126 and 127 horizontally toward the chamber 112 to strike the module 14 at oppositely spaced sides thereof and particularly along the notches 101 and 102, respectively. The operation of the series of knives 114 116, 121-123, 126 and 127 function to simultaneously split the module 14 along three different planes, i.e. plane 28, 51; plane 33, 56; and plane 31, 54. The splitting machine 110 thereby causes the module 14 to split into two blocks 12 and 13, with block 12 having a series of front facing areas 25, 26, 27 each having a different area and each spaced by a markedly difEerent distance from the backwall 18, and block 13 having a series of front facing areas 48, 49 and 50 each having a different area and each spaced by a markedly different distance from the backwall 41. The openings 103 and 104 which provide the series of notches 105, 106, 107 and 108 together with the externally facing notches 101 and 102 assist in providing a controlled fracture of the composite 14 to provide the distinct and separable surface areas which substantially differ from adja-cent areas. The splitting causes an irregular fracture to provide an extremely decorative rough appearance which is highly attractive particularly when placed in a wall formation.
After the composite 14 has been split into two separate blocks 12 and 13, the splitting machine 110 retracts the knives 121-123, 126 and 127 from the splitting chamber 112 and thereafter ejects the pair of blocks 12 and 13 by one or more reciprocat-ing levers (not shown) to transfer the pair of blocks 12 and 13 along an exit conveyer 128 so that the blocks may be readily stacked for storage or shipment.
A series of blocks 12 and 13 may be u.tilized to construct a masonry wall laid up in courses as illustrated at 130, 131 and 132 in Fig.
11. Each block is connected to adjacent blocks by conventional mortared joints 133. Duplicate blocks : 25 12 and 13 in each course are identified by numbers primed and double-primed. Further, the blocks in courses 131 and 132 have been identified by the addition of letters A and B, respectively. The courses 130, 131 and 132 have been laid in a running bond so that a single block in upper courses will rest upon two lower blocks and the series of cores 20 and 45 will be aligned in a vertical column to Eorm the wall 134, as illustrated in Fig. 11.
The wall 134 provides a distinct decora-tive appearance in that each decorative sur:Eace areain one course is spaced out of vertical alignment %t~
with an adjacent surface area in another immediately adjacent course. The wall 134 thus provides a plurality of surface areas of difEerent depths for a random decorative appearance. Further, the surface areas in one course will have a different width than vertica]ly spaced sur~ace areas to provide a completely random pattern and appearance.
The method of constructing plural blocks each containing plural split decorative wall areas has been found to be extremely economical to provide high quality building-type blocks which provide a distinctive randomly orientated multiple split type appearance, Each block may be used in various orientations with other blocks mounted adjacently in each course or in adjacent cour,ses to provide a usual decorative wall appearance.

After the prongs 81 and 82 of divider 80 are placed within the mold box 65, cement-like material such as concrete or the like is placed within the cavity 74 and permitted to harden to form a unitary composite 1~. Either while the cement-like material is hardening or after it has hardened and cured, the division plate 80 and the retaining 15 bars 76 and 78 and associated form members 75, 77 and 79 are removed thereby leaving a unitary compos-ite 14 as illustrated in Fig. 3.

Following the removal from the molding box 65, the composite 14 progresses along a conveyer 109 to a splitting apparatus 110. The splitter 110 may be selected from any one o a number of known commercial cement block splitting machines, such as marketed by Columbia Machine, Inc. of Vancouver, Washington, but modified to have plural cutting blades as more fully set forth hereafter. As the composite 14 reaches a predetermined point, limit ; switches or other sensing devices activate a series of arms 111 which operate to transfer composite 14 into a splitting chamber 112 provided by the splitting machine 110. The splitting machine 110 includes a base member 113 which retains a series of splitting blades as illustrated at 114, 115 and 116.
` 20 The base or bed ]13 is supported by a series of supports 117 which, in turn, ~urther support a series of upwardly directed threaded rods 118. An upper carriage 119 is mounted upon rods 118 and is selectively activated to move vertically. A
plate assembly 120 is mounted on a lower portion oE
carriage 119 and includes three spaced splitting blades 121, 122 and 123 which are aligned with associated splitting blades 114, 115 and 116 mounted therebelow~ In such manner, the pair of splitting blades 114 and 121 are mounted within the same splitting plane and are designed to be aligned with the module 14 along the splittiny plane 28, 51. In like manner, the pair of splitting blades llS and 122 are aligned within the same plane and are designed to be aligned with the splitting plane 33, 56 of module 14.

The reciprocating piston 124 provides a splitting blade 126 which is adapted to be aligned with notch 101 of module 14 which corresponds to the plane 28, 51. The reciprocating piston 125 also includes a splitting blade 127 which is situated to be aligned with notch 102 of module 14 and therefore ali~ned with the plane 31, 54.
