Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
107 words
A shearing tool comprising an inverted U-shaped relatively large heavy steel body member as compared with structural members such as beams in a building being dismantled and including a horizontal upper section, right angular lower horizontal edges on said horizontal upper section and a pair of spaced depending vertical sections integral with said horizontal upper section and means on said horizontal upper section to which a supporting element can be attached whereby the shearing tool may be alternately lifted and dropped so as to move downwardly straddling said structural member to be sheared so as to shear the same upon impact of said horizontal upper section therewith.
Claim 2
Dependent Claim
107 words
A shearing tool comprising an inverted U-shaped relatively large heavy steel body member as compared with structural members such as beams in a building being dismantled and including a horizontal upper section, right angular lower horizontal edges on said horizontal upper section and a pair of spaced depending vertical sections integral with said horizontal upper section and means on said horizontal upper section to which a supporting element can be attached whereby the shearing tool may be alternately lifted and dropped so as to move downwardly straddling said structural member to be sheared so as to shear the same upon impact of said horizontal upper section therewith.
Claim 3
Dependent Claim
23 words
The shearing tool set forth in claim 1 and wherein said means on said horizontal upper section comprises an upwardly extending apertured bracket.
Claim 4
Dependent Claim
34 words
The shearing tool set forth in claim 1 wherein the pair of spaced depending vertical sections define a vertically extending slot of a width greater than that of a structural member to be sheared.
Claim 5
Dependent Claim
34 words
The shearing tool set forth in claim 1 and wherein said body member is vertically elongated so that a majority of said tool and the weight thereof lies below the horizontal upper section thereof.
Claim 6
Dependent Claim
38 words
The shearing tool set forth in claim 1 and wherein said depending vertical sections are substantially square in cross section and the horizontal upper section has a depth dimension equal to the depth dimension of the vertical sections.
Claim 7
Dependent Claim
39 words
The shearing tool set forth in claim 1 wherein the width of the horizontal upper section is substantially four times the width of the depending vertical sections and substantially double the width of the space between said vertical sections.
