1,105,240. Aligning vehicle wheels. BISHMAN MANUFACTURING CO. Nov. 21, 1966 [Dec. 1, 1965], No. 52104/66. Heading G1X. Apparatus for aligning vehicle wheels comprises a support for a wheeled vehicle (not shown) having work stations positioned adjacent each wheel of a vehicle an elongated reference marker, as 13, at each work station, the reference markers being disposed parallel to each other, a portable gauge 30 for attachment to the hub 53 of a vehicle wheel and having an aperture containing an optical reference line 37 defining an axis 54, and a portable adjustable reference member 20, having a base member 21 with grooves on its underside for location on the elongated reference marker, as 13, at the particular work station, and an upper adjustable member 25 pivotally mounted for rotation about an axis 38 on the base member 21 and having indicia lines marked on its upper surface for alignment with the reference line 37. In use the vehicle is driven on to the support and the gauge 30 is fixed e. g. by magnetic attraction to a machined face on one of the rear wheels of the vehicle. This machined face is assumed to be parallel to the centre line 46 of the vehicle. The reference member 20 is placed on the appropriate reference marker 13 and the upper member 25 rotated until the indicia lines thereon are in alignment with the line 37 on the gauge 30. The gauge 30 and member 20 can then be moved to the other work stations to check the alignment of the other wheels of the vehicle. The part of the gauge which contacts the wheel are made from two relatively rotatable members so that the angular relationship between the line 37 and the face of the gauge contacting the wheel can be adjusted, to enable a check to be made on the correct toe-in angle of the front wheels of the vehicle. In an alternative arrangement the line 37 is arranged to be adjustable about a vertical axis on the gauge 30 and in this case the member 25 remains stationary on the base 21 during adjustment. Also if desired wires 55 may be used in place of the fixed reference markers 13 at each work station. |
