Title: Drill pipe turning device

Abstract

This patent describes a tool conformed to clamp onto segments of pipe and to advance in rotation the segments, including a frame, two opposed jaw-like arms each of the arms at a first end thereof attached to the frame by a pivotal mount and each arm including rolling means at a free second end thereof, a chain loop, a motor attached to the frame for advancing the chain loop, the motor including a drive sprocket thereon. The chain loop extends around and in engagement with the drive sprocket, the pivotal mounts, and the rolling means; the arms each including levers radially extending from the pivoted mounts and projecting over the frame; a pair of shuttles slidably mounted on the frame and having camming means to abut against the levers to pivotally articulate the arms around the pivotal mounts in the course of the translation of the shuttles; a pair of shuttle idles supported for rotation on the shuttles and aligned to engage the exterior of the chain loop; and actuating means operatively connected for translating the shuttles.
