Abstract: A support block for use with other similar support blocks to support a die in an elevated position above a factory floor. Each support block comprises a body having a horizontal top surface for supporting a flange extending laterally outwardly from the bottom of the die. A vertical rod is slidably received in a central bore of the body and has a head on the upper end. The rod is disposed in a notch in the bottom flange of the die and a spring in the body urges the rod down to clamp the flange between the top surface of the body and a washer under the head of the rod. The rod has a spacer between the head and the top surface of the body to maintain a minimum spaced relation between the head of the rod and the top surface of the body. The support block is tethered to an anchor on the die by an elongated flexible linear member which is of sufficient length to enable the support block to be positioned under the die flange with its rod in one of the notches.
