Abstract
Abstract A machine for fabricating workpieces, provided with shears, punches, press brakes, a notcher or coper, and other accessories, such as forming, shaping, bending and cut-off tooling, has a power beam swingable vertically on a horizontal bed that is interposed between the beam and a hydraulic ram, as well as other associated parts under the bed, which operably connect the ram with the beam. The connecting parts include a linkage and a bell crank so arranged as to apply pressure that is fully adequate to carry out a multiplicity of operations along the entire beam of relatively heavy, thick metal stock of any length and of numerous shapes. One of the shear knives is floatingly mounted on the beam in a novel manner to properly handle L-shaped or other angle members.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
170 words
In a machine for fabricating workpieces: a horizontally extending bed; an elongated, generally horizontally extending beam disposed above said bed; pivot means supporting the beam for swinging movement toward and away from the bed about an axis disposed transversely of the beam, said beam and said bed having opposed sets of mutually cooperable tool means spaced therealong with certain sets disposed further from said axis than others; power means disposed below said bed and including a reciprocable member having a stroke of predetermined length; upright linkage depending from said beam to a position below said bed and spaced laterally from said pivot means; and a swingable crank intercoupling said member and the lower end of the linkage for swinging the beam about said axis during actuation of said power means, said crank disposing said linkage for movement of the linkage through a displacement substantially less than said stroke of the member whereby to multiply the force applied by said power means to the beam during actuation of the power means.
Claim 2
Dependent Claim
170 words
In a machine for fabricating workpieces: a horizontally extending bed; an elongated, generally horizontally extending beam disposed above said bed; pivot means supporting the beam for swinging movement toward and away from the bed about an axis disposed transversely of the beam, said beam and said bed having opposed sets of mutually cooperable tool means spaced therealong with certain sets disposed further from said axis than others; power means disposed below said bed and including a reciprocable member having a stroke of predetermined length; upright linkage depending from said beam to a position below said bed and spaced laterally from said pivot means; and a swingable crank intercoupling said member and the lower end of the linkage for swinging the beam about said axis during actuation of said power means, said crank disposing said linkage for movement of the linkage through a displacement substantially less than said stroke of the member whereby to multiply the force applied by said power means to the beam during actuation of the power means.
Claim 3
Dependent Claim
25 words
In a machine as claimed in claim 1, said crank being swingable on said bed about an axis parallel with said axis of the beam.
Claim 4
Dependent Claim
17 words
In a machine as claimed in claim 2, said linkage pivotally interconnecting the beam and the crank.
Claim 5
Dependent Claim
14 words
In a machine as claimed in claim 3, said member being fluid pressure actuated.
Claim 6
Dependent Claim
35 words
In a machine as claimed in claim 1; and an angle shear intermediate the ends of said bed and beam including a floating cutter blade mounted for self alignment with the work piece being severed.
Claim 7
Dependent Claim
28 words
In a machine as claimed in claim 1, said blade being secured to the beam for swinging movement about an axis parallel with said axis of the beam.
Claim 8
Dependent Claim
147 words
In a machine for fabricating workpieces: a bed; an elongated beam pivotally supported for swinging movement in an arcuate path of travel toward and away from said bed; a stationary, generally V-shaped shear blade mounted on said bed adjacent the axis of swinging movement of said beam for complementally receiving an article to be severed having a similar cross sectional configuration; and a floating cutter blade mounted on said beam adjacent said axis in position to cooperate with said shear blade in severing the article when the beam is swung toward said bed, said cutter blade being generally complemental to said shear blade and being mounted for pivoting movement about an axis transverse to the arcuate path of travel of said beam whereby the cutter blade can remain complementally aligned with the shear blade and article during severance of the latter notwithstanding arcuate movement of the Beam.
Claim 9
Dependent Claim
147 words
In a machine for fabricating workpieces: a bed; an elongated beam pivotally supported for swinging movement in an arcuate path of travel toward and away from said bed; a stationary, generally V-shaped shear blade mounted on said bed adjacent the axis of swinging movement of said beam for complementally receiving an article to be severed having a similar cross sectional configuration; and a floating cutter blade mounted on said beam adjacent said axis in position to cooperate with said shear blade in severing the article when the beam is swung toward said bed, said cutter blade being generally complemental to said shear blade and being mounted for pivoting movement about an axis transverse to the arcuate path of travel of said beam whereby the cutter blade can remain complementally aligned with the shear blade and article during severance of the latter notwithstanding arcuate movement of the Beam.
Claim 10
Dependent Claim
19 words
In a machine as claimed in claim 7; and means limiting the extent of pivoting movement of said blade.
