Abstract
Abstract The apparatus for shearing a stated quantity of each of a number of different sized parts from sheet stock including a shear having gauges set automatically to determine the amount of cutoff, controlled means for returning predetermined cutoffs to the operator for further processing, and a control structure to indicate to an operator the orientation of stock feed for the next cut.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
In a power operated manually fed shear having a gauge to determine the amount of cutoff and wherein optimum cuts for minimizing scrap are determined in advance and appropriate gauge settings made automatically, the improved structure comprising: a. first and second indicator means, at least one of said indicator means being arranged to display the gauge setting of said shear for the next cut; b. third indicator means arranged to display the finished length of the desired part; c. fourth indicator means arranged to display the finished width of the desired part; and d. means for actuating only one of said first, second, third, and fourth indicator means to indicate to an operator the orientation of stock feed for the next cut.
Claim 2
Dependent Claim
122 words
In a power operated manually fed shear having a gauge to determine the amount of cutoff and wherein optimum cuts for minimizing scrap are determined in advance and appropriate gauge settings made automatically, the improved structure comprising: a. first and second indicator means, at least one of said indicator means being arranged to display the gauge setting of said shear for the next cut; b. third indicator means arranged to display the finished length of the desired part; c. fourth indicator means arranged to display the finished width of the desired part; and d. means for actuating only one of said first, second, third, and fourth indicator means to indicate to an operator the orientation of stock feed for the next cut.
Claim 3
Dependent Claim
100 words
In a power operated manually fed shear, the improved combination including: a. a gauge to determine the amount of cutoff; b. power operated means for moving said gauge; c. means for actuating said power operated means; d. means for determining optimum cutoffs whereby to minimize scrap, said means for actuating said power operated means being responsive to said means for determining optimum cutoffs; e. means selectively operable to return predetermined cutoffs to the operator for further processing and to discard scrap cutoffs; and f. control structure arranged to indicate to an operator the orientation of stock feed for each cut.
Claim 4
Dependent Claim
100 words
In a power operated manually fed shear, the improved combination including: a. a gauge to determine the amount of cutoff; b. power operated means for moving said gauge; c. means for actuating said power operated means; d. means for determining optimum cutoffs whereby to minimize scrap, said means for actuating said power operated means being responsive to said means for determining optimum cutoffs; e. means selectively operable to return predetermined cutoffs to the operator for further processing and to discard scrap cutoffs; and f. control structure arranged to indicate to an operator the orientation of stock feed for each cut.
Claim 5
Dependent Claim
92 words
In a power operated manually fed shear having a gauge adjustable to determine the amount of cutoff and wherein optimum cuts for minimizing scrap are determined in advance and appropriate gauge settings made automatically, the improved control structure comprising: visual display means for indicating to an operator the orientation of stock feed for the next cut, said means comprising two indicators, at least one of said indicators being adapted to displAy the gauge setting of said shear for the next cut, only said last mentioned indicator being displayed for said next cut.
Claim 6
Dependent Claim
92 words
In a power operated manually fed shear having a gauge adjustable to determine the amount of cutoff and wherein optimum cuts for minimizing scrap are determined in advance and appropriate gauge settings made automatically, the improved control structure comprising: visual display means for indicating to an operator the orientation of stock feed for the next cut, said means comprising two indicators, at least one of said indicators being adapted to displAy the gauge setting of said shear for the next cut, only said last mentioned indicator being displayed for said next cut.
