Abstract:
A fractional-weight holding, weight stack selector shear pin for supporting at least one supplementary, fractional weight member having an aperture and for selecting an effective number of weight plates in a weight stack by inserting the fractional-weight holding, weight stack selector shear pin into operative engagement with a bottom weight plate of the selected weight plates and into operative engagement with a weight plate lifting rod to support the bottom weight and those selected weight plates above the bottom weight plate to the weight plate lifting rod, said fractional-weight holding, weight stack selector shear pin comprising:a shear pin having an axial length, a first end of said shear pin for engagement with the plate lifting rod, and a second end of said shear pin coaxial with said first end and for selectively supporting the at least one supplementary, fractional weight member; a first flange and a second flange located at said second end of said shear pin; and said second flange axially spaced from said first flange and selectively, axially movable along said second end of said shear pin, wherein the at least one supplementary, fractional weight member may be securely clamped between said first and second flanges and prevented from axial movement along said second end of said shear pin.
