  • Patent number: 4261194
    Abstract: A multiple indent die device for use with compression tools for crimping ductile tubular connectors on cables and the like. The device includes a pair of opposed die holders adapted for mounting between the ram and anvil of a compression tool for movement toward and away from each other. Each die holder includes a constrained indentor die which moves relative to the other indentor die and solely in the direction of movement of the die holders. A first movable indentor die is pivotally mounted to one of the die holders and about an axis which is parallel to the axis of the tubular connector and engages an inclined surface on the other die holder for radially inward movement toward the axis of the tubular connector and generally between the constrained indentor dies as the die holders are moved toward one another. A second movable indentor die is similarly mounted to either one of the die holders for engaging an inclined surface on its opposed die holder.
