Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
A post hole block comprising a body of heavy material, substantially rectangular in horizontal cross-section and horizontally elongated, said body being provided midway between its longer sides with a vertical hole to receive a post, and the upper surface of the body spaced from said hole being lower than the upper surface adjacent said hole, the block having a central section and lower end sections, said hole being in the center of the central section, and at least a portion of the upper surface of each end section sloping upward to the level of said central section, said block being traversed by additional smaller holes each extending from points on the upper surface spaced from said vertical hole downward through the body.
Claim 2
Dependent Claim
122 words
A post hole block comprising a body of heavy material, substantially rectangular in horizontal cross-section and horizontally elongated, said body being provided midway between its longer sides with a vertical hole to receive a post, and the upper surface of the body spaced from said hole being lower than the upper surface adjacent said hole, the block having a central section and lower end sections, said hole being in the center of the central section, and at least a portion of the upper surface of each end section sloping upward to the level of said central section, said block being traversed by additional smaller holes each extending from points on the upper surface spaced from said vertical hole downward through the body.
Claim 3
Dependent Claim
25 words
A post hole block according to claim 1 wherein said points are closer to the ends of the end sections than to the central section.
Claim 4
Dependent Claim
107 words
A post hole block comprising a body of heavy material, substantially rectangular in horizontal cross-section and horizontally elongated to comprise a central section and lower end sections, said body being provided with a vertical hole in the central section to receive a post, each end section being traversed by an additional smaller hole extending downward through the body from a point on the upper surface of the end section closer to the end of the end section than to the central section, and an elongated spike in each said additional hole, extending a substantial distance below the bottom of the block and made rigid with the block.
Claim 5
Dependent Claim
107 words
A post hole block comprising a body of heavy material, substantially rectangular in horizontal cross-section and horizontally elongated to comprise a central section and lower end sections, said body being provided with a vertical hole in the central section to receive a post, each end section being traversed by an additional smaller hole extending downward through the body from a point on the upper surface of the end section closer to the end of the end section than to the central section, and an elongated spike in each said additional hole, extending a substantial distance below the bottom of the block and made rigid with the block.
Claim 6
Dependent Claim
72 words
A post hole block comprising a body of heavy material, substantially rectangular in horizontal cross-section and having substantially vertical side and end surfaces, said body being traversed centrally by a vertical hole to receive a post, the upper surfaces of the body sloping downward and outward from lines near the hole, and the body being traversed by additional smaller holes each extending from one of the sloping surfaces downward through the body.
Claim 7
Dependent Claim
72 words
A post hole block comprising a body of heavy material, substantially rectangular in horizontal cross-section and having substantially vertical side and end surfaces, said body being traversed centrally by a vertical hole to receive a post, the upper surfaces of the body sloping downward and outward from lines near the hole, and the body being traversed by additional smaller holes each extending from one of the sloping surfaces downward through the body.
