Abstract
Abstract A ratchet barrel is placed upon the lower half of sucker rod joint. A wrench is placed upon the upper half of the joint. A torque handle is pivoted to the wrench. A pawl upon the torque handle engages a ratchet wheel upon the barrel to tighten or loosen the joint. A stop upon the wrench permits the wrench to be rotated by the torque handle without the assistance of the ratchet and pawl mechanism.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
194 words
A tool for connecting and disconnecting two elongated coaxial elements threaded together along their axes comprising: a. a ratchet wheel on and coaxial with b. a barrel, c. the barrel having a rod slot so that the barrel may be placed coaxially on one of the coaxial elements with the ratchet wheel coaxial to the elements, d. barrel jaw means for attaching the barrel to the coaxial elements upon which it is placed, e. a wrench with wrench jaw means for attaching the wrench to the other of the coaxial elements, f. an elongated torque handle extendably radially of the wrench, g. a pawl on the handle engaging the ratchet wheel, and h. a removable pin extending through at least one hole in e. a pivoted end of said torque handle, j. said pin also extending through k. a radially extending slot in the end of the wrench fitting at the joint to the torque handle, thus forming l. pivot means innerconnecting the wrench and handle for pivoting the handle to the wrench so that the pawl may engage and disengage the ratchet wheel upon movement of the handle within the radially extending slot.
