Two rectangular housings are mounted in a pair of spaced recesses in a garage floor to have cover means thereon moved to closed positions flush with the floor surface. Mounted in one end of each housing beneath a first cover is a rotatable wheel-supporting pad, which is slidable longitudinally of the housing, and is reciprocable vertically by a pneumatically operated scissors jack. Each housing has pivoted on its opposite end a second cover which carries on its inside surface a laser, a mirror, and a conventional alignment chart for denoting toe in, toe out, camber, etc., all of which items are disposed within one section of the housing when the pivotal cover is closed. When the pivotal covers are swung to upright positions, each laser directs a beam of light upwardly onto the associated mirror, which is inclined at 45°to the vertical, so that the mirrors direct their beams horizontally through an aperture in the center of the associated chart and coaxially toward one another. The lasers, mirrors and charts are adjustably mounted on their respective pivotal covers so that the beams of light can be properly focused. The apparatus is particularly suited for use with a garage bay of the type having a lift for engaging the frame of an auto to raise and lower the latter.

Apparatus for use in aligning the front wheels of automotive vehicles, comprising a housing adapted to be mounted on a garage floor, or the like, and having an opening in a top portion thereof defining a plane, means for covering said opening in the top portion of said housing, including a first cover movable on said housing between a closed position in which a plane surface thereon registers approximately with the top portion of the housing to cover at least one portion of said opening, and an upright position in which said first cover extends above said housing, and alignment checking means including a light source mounted on said first cover to be supported thereby within a first section in said housing and beneath the top portion of said housing, when said first cover is closed, and to be supported thereby in an operative position above said housing, when said first cover is in its upright position, said alignment checking means further including means for directing a beam of light from said source substantially horizontally and at a height sufficiently above the housing to cause the beam to be directed toward the approximate center of a wheel of an adjacent automotive vehicle, or the like, when said first cover is in its upright position.
