Abstract: A computer controlled laser machine tool is provided wherein the machine tool work zone is smaller than the size of the workpiece that can be processed. The machine tool has an apparatus to register the workhead guidance system to the workpiece without requiring a hole in the workpiece. The machine tool is adapted with an image sensor, a form of a digital camera, to measure the position of targets etched in or affixed to the surface of the workpiece. Registration of the workhead guidance system relative to the workpiece is checked before and after the workpiece support is indexed.

Abstract: A wheel alignment adjustment device comprising a first member adapted for supporting an elongate shaft portion of a vehicle wheel suspension assembly and a plurality of parallel overlapping bores extending through the first member adapted for axially receiving the elongate shaft portion in a selected one of the bores and for maintaining the elongate shaft portion in a radially stationary position therein.

Abstract: A bushing assembly for adjusting at least one wheel alignment parameter for use in a vehicle wheel suspension system of the type having a suspension member with a bore therein adapted for mounting a ball-joint-shaft-receiving bushing and with at least one positioning surface located adjacent to the bore in the suspension member, including a bushing member with a generally cylindrical body portion and a radially extending head portion having a ball joint shaft receiving bore therethrough; an annular locking member having at least one recess in a bottom portion thereof for engaging the suspension member locating surface; and a post member insertable through axially extending peripheral bores in the locking member and the bushing head portion for adjustably locking the bushing member against rotation with respect to the locking member, the locking member being positioned between the bushing head portion and the suspension member.

Abstract: A camber adjustment device including a cam bolt and cam plate assembly and method of installation thereof which enables a vehicle to be quickly and conveniently provided with an assembly for adjusting the front wheel camber.

Abstract: A system for providing toe and camber adjustment for a wheel drum which is normally fixed in location on a vehicle wherein one end of a control arm is relatively fixedly mounted on the wheel drum and the other end of the control arm is mounted for movement in an arcuate path about a relatively fixed axis for changing the angular relationship between the longitudinal axis of the vehicle and the rotational axis of the wheel drum so as to vary the toe and camber of the wheel drum.
