Abstract

See full text

A pipe gripping apparatus has a first jaw with a pipe-contacting surface at one end thereof, a second jaw having a pipe-contacting surface at one end thereof, a tongue having a pipe-contacting surface at one end thereof, and an actuator connected to the first and second jaws and to the tongue. The actuator serves to move the first and second jaws and the tongue such that the pipe-contacting surfaces thereof move radially inwardly simultaneously for a substantially identical distance. A first link pivotally connects the tongue with the first jaw. A second link pivotally connects the tongue with the second jaw. The first and second links extend angularly outwardly from the tongue. The first and second pivot points of each jaw have a distance unequal to a distance between the first pivot point and pipe-contacting surface of each jaw. The pipe-contacting surfaces can be elastomeric pads, toothed dies, or rollers.
