Abstract
Abstract Apparatus for sawing metal elements transversely at a plurality of angles by means of a vertically-displaceable blade in which there is provided a bench top including an angularly adjustable clamp stop at one side of the axis of rotation of the saw-blade, and a pair of opposed clamp stops are adjustable at the opposite side of the axis of rotation of the saw-blade for permitting the saw to effect transverse cuts at various angles while the work piece is urged into the bench top by a vertical, adjustable stop. The machine base means permits the saw to be adjusted angularly and longitudinally of the work piece on an axis of rotation coinciding with an abutment edge of one stop toward which the work piece being cut is urged when a cut is being made.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
169 words
An apparatus for sawing steel profiles by a vertically displaceable circular saw blade overlying a horizontal work bench, including combined clamp and stop assemblies disposed on opposite sides of the blade for engaging the work piece at the opposite side at the area in which a vertical cut is to be made, the improvement in which one combined clamp and stop assembly includes a vertical abutment face for engaging one side of the work piece, said blade being rotatable toward said face for urging the work piece thereagainst as a cut is effected, said stop assembly including means for adjustably rotating said vertical abutment face relative to the cutting plane of said saw blade and the cutting plane of the saw blade intersecting and passing through said vertical abutment face, said vertical abutment face including a circular segmental guide having a center coinciding with the abutment face, and an intermediate plate secured to the work bench and having arcuate guide means upon which said stop assembly is adjustably mounted.
Claim 2
Independent Claim
169 words
An apparatus for sawing steel profiles by a vertically displaceable circular saw blade overlying a horizontal work bench, including combined clamp and stop assemblies disposed on opposite sides of the blade for engaging the work piece at the opposite side at the area in which a vertical cut is to be made, the improvement in which one combined clamp and stop assembly includes a vertical abutment face for engaging one side of the work piece, said blade being rotatable toward said face for urging the work piece thereagainst as a cut is effected, said stop assembly including means for adjustably rotating said vertical abutment face relative to the cutting plane of said saw blade and the cutting plane of the saw blade intersecting and passing through said vertical abutment face, said vertical abutment face including a circular segmental guide having a center coinciding with the abutment face, and an intermediate plate secured to the work bench and having arcuate guide means upon which said stop assembly is adjustably mounted.
Claim 3
Dependent Claim
28 words
The structure as claimed in claim 1, including means for adjustably mounting said vertical abutment face toward and away from the axis of rotation of said saw blade.
Claim 4
Dependent Claim
23 words
The structure as claimed in claim 2 in which said intermediate plate includes depending guide elements extending radially from the arcuate guide means.
Claim 5
Dependent Claim
28 words
The structure as claimed in claim 2 including brake means engageable between said bench top and said stop assembly for retaining the stop assembly in an adjusted position.
Claim 6
Dependent Claim
18 words
The structure as claimed in claim 4 in which said brake means comprises a fluid pressure actuated assembly.
Claim 7
Independent Claim
175 words
An apparatus for sawing steel profiles by a vertically displaceable circular saw blade overlying a horizontal work bench, including combined clamp and stop assemblies disposed on opposite sides of the blade for engaging the work piece at the opposite side at the area in which a vertical cut is to be made, the improvement in which one combined clamp and stop assembly includes a vertical abutment face for engaging one side of the work piece, said blade being rotatable toward said face for urging the work piece thereagainst as a cut is effected, said stop assembly including means for adjustably rotating said vertical abutment face relative to the cutting plane of said saw blade and the cutting plane of the saw blade intersecting and passing through said vertical abutment face, said stop assembly being integral with a base, said work bench including a counter stop opposite the adjustably-rotatable stop assembly, said work bench including means for rotating said saw blade and counter stop relative to said adjustably-rotatable stop assembly on a vertical axis of rotation.
Claim 8
Independent Claim
175 words
An apparatus for sawing steel profiles by a vertically displaceable circular saw blade overlying a horizontal work bench, including combined clamp and stop assemblies disposed on opposite sides of the blade for engaging the work piece at the opposite side at the area in which a vertical cut is to be made, the improvement in which one combined clamp and stop assembly includes a vertical abutment face for engaging one side of the work piece, said blade being rotatable toward said face for urging the work piece thereagainst as a cut is effected, said stop assembly including means for adjustably rotating said vertical abutment face relative to the cutting plane of said saw blade and the cutting plane of the saw blade intersecting and passing through said vertical abutment face, said stop assembly being integral with a base, said work bench including a counter stop opposite the adjustably-rotatable stop assembly, said work bench including means for rotating said saw blade and counter stop relative to said adjustably-rotatable stop assembly on a vertical axis of rotation.
Claim 9
Dependent Claim
23 words
The structure as claimed in claim 6 in which the vertical axis of rotation coincides with the vertical abutment of said stop assembly.
Claim 10
Dependent Claim
41 words
The structure as claimed in claim 7 in which said work bench is mounted for horizontal movement relative to the base and in the cutting plane of said saw blade whereby the saw is adjustable loNgitudinally relative to the work piece.
