20090165601 | Backup wrench - The benefit of and the practical side of the improvement, by adding the retaining shoulder to the jaws of the wrench on the box-end and the open-end parts of the wrench, is the decline of slippage and limited loss of control of the tightening or removal procedure, producing an ease of maintaining one's position on the bolt or nut when the vibration of an impact wrench is incorporated or manual procedures, no matter how precarious the position or how open the position is to the mechanic, technician, or untrained shop help. This Backup Wrench does not allow the nut or bolt to skip through the jaws of the wrench whether on open-end or box-end as it has a built-in stop. The stop holds the nut but alls the bolt to protrude without affecting the Backup Wrench's position. Sizes range from ¼″ on up to any size desired—American or Metric. | 07-02-2009 |

20100101378 | AUTOMATIC SLACK ADJUSTER TOOL - A pawl disengagement tool intended for use with a slack adjuster has an elongated handle with a first end and an opposite second end, and a longitudinal axis extending from the first end to the second end. A slotted aperture formed at the first end includes a hole with a diameter that is greater than the first diameter of the pawl cap. A first slot extends from the hole and has a width that is greater than the second diameter of the pawl shaft of the pawl assembly of the slack adjuster. A portion of the tool defining the hole includes a chamfered periphery. The chamfered periphery defines an inclined plane leading to the first slot.
