  • Patent number: 6240649
    Abstract: A sighting assembly for providing a reference laser beam in the course of connecting pipe segments to each other includes an elongate body in which a laser pointing course is received and which is pivotally engaged at its front end to an straight edged arm. The body may further include a magnetic compass and a level assembly, both proximate its rear end, to provide a visual indication of the azimuth and inclination thereof. These are achieved by an azimuth ring on the compass projecting into lateral cutouts in the body for manipulative convenience. In one example the arm supports two spaced posts, each including spaced projections for contacting the pipe segment, and when the arm is collapsed below the body for storage the posts are received in the cutouts.
