Abstract
Abstract An apparatus is disclosed which monitors in a continuous manner the parallel alignment between the shafts of two coupled rotating machines while the machinery is in service. The apparatus consists of a pair of anchors for securing the elements to the machines, a bar slidably mated with the anchors spanning the distance between the machines, gauge holders slidably located on the bar and gauges secured to the holders so that the measuring means is in contact with the hub of each machine. The apparatus allows both horizontal and vertical alignment measurements to be made while the machines are operating.
