Total Claims: 6
Claim 1
Independent Claim
169 words
A generally rectangular hollow concrete building block for use in constructing concrete block walls including a concrete footing having a row of uniformly spaced and vertically extending reinforcing bars anchored therein, said block having at least one generally rectangular opening extending vertically therethrough and having flat top, bottom, side and end walls, securing bar retaining and locating means embedded in the interior of said walls and extending transversely into the center of said opening, said bar retaining means having one end fixedly embedded in one wall of opening and extending into the center thereof where it is twisted to form a transversely positioned loop in the center of said opening and its other end fixedly embedded in an adjacent wall, said block being positionable above said reinforcing bars with said opening and said loop alignable therewith and moved downwardly thereover whereby said bars are sleeved through said loops and aligned and retained in end to end abutting relation relative to each other in courses without the use of mortar.
Claim 2
Dependent Claim
169 words
A generally rectangular hollow concrete building block for use in constructing concrete block walls including a concrete footing having a row of uniformly spaced and vertically extending reinforcing bars anchored therein, said block having at least one generally rectangular opening extending vertically therethrough and having flat top, bottom, side and end walls, securing bar retaining and locating means embedded in the interior of said walls and extending transversely into the center of said opening, said bar retaining means having one end fixedly embedded in one wall of opening and extending into the center thereof where it is twisted to form a transversely positioned loop in the center of said opening and its other end fixedly embedded in an adjacent wall, said block being positionable above said reinforcing bars with said opening and said loop alignable therewith and moved downwardly thereover whereby said bars are sleeved through said loops and aligned and retained in end to end abutting relation relative to each other in courses without the use of mortar.
Claim 3
Dependent Claim
70 words
A concrete building block according to claim 1, wherein said block is formed with a pair of generally rectangular openings separated by a central rib, and said bar retaining means is embedded in a wall of one opening and extends through said central rib and is embedded in a wall of the other opening, said bar retaining being formed with a transversely positioned loop in the center of each opening.
Claim 4
Dependent Claim
72 words
A concrete building block according to claim 2, wherein one end of said bar retaining means is embedded in a wall of one of said openings and projects inwardly into the center of said opening where it is looped and thence extends through said central rib and into said other opening where it is looped in the center thereof and projects laterally and is embedded in a wall of said other opening.
Claim 5
Dependent Claim
88 words
A concrete building block according to claim 3, wherein one end of said bar retaining means is embedded in a rear wall of one of said openings and projects inwardly and at right angles therefrom into the center of said opening where it is looped and thence a portion thereof extends longitudinally through said central rib and into the center of the other of said openings where it is looped and projects laterally at right angles therefrom and is embedded in a front wall of said other opening.
Claim 6
Dependent Claim
38 words
A concrete building block according to claim 4, wherein said bar retaining means is generally of zig-zag shape, and the terminal ends thereof are bent laterally for anchoring said bar retaining means in said rear and front walls.
