Abstract
An alignment gauge for use in determining whether two elongated members, such as cylindrical rolls, are in parallel relationship. The gauge includes a rod or standard, and a pad is connected to a micrometer and is mounted for lateral movement with respect to the rod. A level having a bubble-containing vial is mounted for pivotal movement with respect to the rod. In operation, the rod is placed tangentially against one of two generally parallel rolls and the pad is placed tangentially against the other of the rolls. The level is then pivoted until the vial is horizontal. The gauge is then positioned in the same manner at the opposite ends of the rolls and the micrometer is adjusted until the vial is horizontal or level. The reading of the micrometer is an indication of the misalignment of the two rolls.
