Abstract
Abstract The apparatus includes an elongated frame structure and a carriage unit movable longitudinally of such structure. A cutting torch assembly is releasably locked on the carriage unit with the cutting member thereof positioned to one side of the frame structure at an angle of about 45* relative to a lateral plane of the frame structure. The frame structure carries clamping means for selective securing the apparatus to the upper end portions of a driven H-beam pile to provide for the successive removal or trimming of the beam side flanges and connecting web such that the resultant terminal top faces of the flanges and web are bevelled and the upper edges of the terminal faces lie in a common horizontal plane normal to the planes of the side flanges and web. A next H-beam, when longitudinally aligned with and supported on the upper edges of the trimmed H-beam, is coupled to the trimmed H-beam by being welded thereto at the bevelled terminal faces.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
274 words
Apparatus for squaring the upper end of a ground driven Hbeam pile having spaced side flanges and a connecting web, comprising: a. an elongated frame structure, b. a cutting torch assembly having a nozzle member with a flame end, c. means releasably supporting the torch assembly on and longitudinally of said frame structure with the flame end of said nozzle member spaced laterally outwardly from one side of said frame structure, d. means movably mounting said supporting means on said frame structure for movement only longitudinally of said frame structure for either a vertically or horizontally extended working position of the frame structure, e. manually operated means for longitudinally moving said mounting means when the frame structure is in a working position therefor, f. means for mounting said frame structure in a vertically extended working position arranged transversely of a side flange along the outer surface thereof with the flame end of the nozzle member adjacent said outer surface whereby on said longitudinal movement of the supporting means a predetermined upper portion of a side flange is cut from the beam, and g. means for mounting the frame structure in a horizontally extended working position supported on the top edges of the foreshortened side flanges and arranged transversely of and along one side of the connecting web with the flame end of the nozzle member adjacent the one side of said web and located in the horizontal plane of said upper edges, whereby on said longitudinal movement of the supporting means a predetermined upper portion of the web, corresponding to said upper predetermined portions of the side flanges, is cut from the beam member.

Apparatus for squaring the upper end of a ground driven Hbeam pile having spaced side flanges and a connecting web, comprising: a. an elongated frame structure, b. a cutting torch assembly having a nozzle member with a flame end, c. means releasably supporting the torch assembly on and longitudinally of said frame structure with the flame end of said nozzle member spaced laterally outwardly from one side of said frame structure, d. means movably mounting said supporting means on said frame structure for movement only longitudinally of said frame structure for either a vertically or horizontally extended working position of the frame structure, e. manually operated means for longitudinally moving said mounting means when the frame structure is in a working position therefor, f. means for mounting said frame structure in a vertically extended working position arranged transversely of a side flange along the outer surface thereof with the flame end of the nozzle member adjacent said outer surface whereby on said longitudinal movement of the supporting means a predetermined upper portion of a side flange is cut from the beam, and g. means for mounting the frame structure in a horizontally extended working position supported on the top edges of the foreshortened side flanges and arranged transversely of and along one side of the connecting web with the flame end of the nozzle member adjacent the one side of said web and located in the horizontal plane of said upper edges, whereby on said longitudinal movement of the supporting means a predetermined upper portion of the web, corresponding to said upper predetermined portions of the side flanges, is cut from the beam member.
Claim 3
Dependent Claim
86 words
The apparatus according to claim 1 wherein: a. said moving means includes a screw shaft extended longitudinally of said frame structure, b. means rotatably supporting said screw shaft on the frame structure, c. a nut member on said supporting means having separable portions movable into and out of threadable engagement with said screw shaft whereby said supporting means is freely movable longitudinally of said frame structure when said separable portions are out of engagement with said screw shaft, and d. means for manually rotating said shaft.
Claim 4
Dependent Claim
119 words
The apparatus according to claim 1 where: a. said frame structure includes a flat base member, and b. the means for mounting the frame structure in said vertically extended working position includes a stationary clamp unit at one end of said base member, and a movable clamp unit, and c. means slidably supporting said movable clamp unit on said base member for adjustable longitudinal movement relative to said stationary clamp unit, d. each of said clamp units including a clamping member adjustably movable toward and away from said base member, whereby when the base member is positioned against the outer surface of a side flange said clamping members are movable into engagement with the inner surface of a flange.
Claim 5
Dependent Claim
139 words
The apparatus according to claim 3, including: a. a pair of like clamp attachments selectively engageable with said stationary clamp unit and movable clamp unit, b. each clamp attachment having a tongue member receivable between the base member and the clamping member of a corresponding clamp unit for releasable securement to the base member, and a U-shape body member having a flat base section continuous with and in the plane of said tongue member and a pair of leg members extended transversely of said base section, and c. a clamping member movably supported on one of said leg members for movement toward and away from the other leg member, each side flange, when the frame structure is in the horizontally extended working position therefor, being receivable between a clamping member and said other leg member of a clamp attachment.
