Abstract
A resistance weight stack for an exercise machine includes a stack of weight plates each having identical sleeves fixed in central apertures of the plates for receiving the weight stack pin. The upper and lower ends of the sleeves each have a plurality of equi-angularly spaced projections and recesses. The projections on the upper ends of the sleeves project above the upper surfaces of the associated weights and are received in the recesses of the lower ends of the next adjacent upper weights for locating and angularly aligning the weight plates relative to each other. The sleeves each have a lateral passage through the wall thereof for allowing a key to be inserted into the weight stack pin to connect the plate to the weight stack pin.
