Abstract
Abstract A light duty stacking assembly for use in conjunction with shears. The assembly includes a conveyor portion and a sheared material stacking portion. The conveyor portion utilizes the force of gravity for moving the sheared material to the stacking portion. Thus, the conveyor of the light duty stacking assembly does not need motor driven belts, chains or the like. The conveyor portion includes an automatically operated scrap separator. The stacking portion provides means for stacking the sheared material into orderly stacks that can be readily moved from the stacker assembly for further processing or shipment as finished products.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
176 words
A light duty stacking assembly for use in conjunction with shears, said assembly comprising a conveyor portion for transporting material from the shears, a stacking portion for use in stacking the transported material, non-motorized means on said conveyor portion for moving the material from the shear to the stacking portion, a stacker rail assembly common to both said stacker portion and said conveyor portion, said stacker rail assebly comprising a pair of support cart frames oppositely disposed from each other, standards on each of said support frames extending vertically upwardly at the shear end of said support cart frames, stacker rail means extending between said standards, means for attaching said conveyor to said rail, back stop means for stopping the sheared material after it slides from the conveyor, said back stop means including angle beam means, side plates for supporting said angle beam means, means for attaching said side plates to saiD rail means for supporting said side plates, and means for enabling said back stop to rotate from a vertical position to a horizontal position.
Claim 2
Dependent Claim
176 words
A light duty stacking assembly for use in conjunction with shears, said assembly comprising a conveyor portion for transporting material from the shears, a stacking portion for use in stacking the transported material, non-motorized means on said conveyor portion for moving the material from the shear to the stacking portion, a stacker rail assembly common to both said stacker portion and said conveyor portion, said stacker rail assebly comprising a pair of support cart frames oppositely disposed from each other, standards on each of said support frames extending vertically upwardly at the shear end of said support cart frames, stacker rail means extending between said standards, means for attaching said conveyor to said rail, back stop means for stopping the sheared material after it slides from the conveyor, said back stop means including angle beam means, side plates for supporting said angle beam means, means for attaching said side plates to saiD rail means for supporting said side plates, and means for enabling said back stop to rotate from a vertical position to a horizontal position.
Claim 3
Dependent Claim
27 words
The light duty stacking assembly of claim 1 wherein means are provided for adjusting the position of the back stop relative to the back of the shear.
Claim 4
Dependent Claim
36 words
The light duty stacking assembly of claim 2 wherein said position adjusting means comprises a groove in each of the side plates, and means for clamping said back stop to a selected position in said groove.
Claim 5
Dependent Claim
129 words
A light duty stacking assembly for use in conjunction with shears, said assembly comprising a conveyor portion for transporting material from the shears, a stacking portion for use in stacking the transported material, said conveyor portion comprising a conveyor biased downwardly from said shear to said stacking portion, whereby said sheared material slides from said shear to said stacking portion, said stacking portion comprising back stop means for stopping the sheared material after it slides from said conveyor portion, said back stop means having a vertical position and a horizontal position and being in the vertical position when stopping the sheared material, and means for enabling said back stop means to rotate from the vertical position to the horizontal position wherein said stacked sheared material is available for removal.
Claim 6
Dependent Claim
129 words
A light duty stacking assembly for use in conjunction with shears, said assembly comprising a conveyor portion for transporting material from the shears, a stacking portion for use in stacking the transported material, said conveyor portion comprising a conveyor biased downwardly from said shear to said stacking portion, whereby said sheared material slides from said shear to said stacking portion, said stacking portion comprising back stop means for stopping the sheared material after it slides from said conveyor portion, said back stop means having a vertical position and a horizontal position and being in the vertical position when stopping the sheared material, and means for enabling said back stop means to rotate from the vertical position to the horizontal position wherein said stacked sheared material is available for removal.
Claim 7
Dependent Claim
75 words
