969,985. Wheel alignment. L. HUNTER. Dec. 10,1962 [July 5,1962], No. 46452/62. Headings G1F and G1M. A wheel alignment apparatus comprises arms 38 each mounted by means of a device 26 to extend parallel to the wheel. A member.86 fixed on arm 38 houses a pivoted lever 90 (Fig. 7) which has an element 93 so that lever 90 may be connected by an elastic member 120 to the lever associated with the opposite wheel. The angle between lever 90 and arm 38 is a measure of the toe in. It is measured by moving a thrust element 116 which acts on a pivoted follower 113 until a contact on the follower engages a contact 95 on lever 90. This closes a circuit and operates a signal e.g. a lamp 107. The amount the thrust element has moved is indicated by a scale 119. The camber, caster and king pin angle can also be measured by means of spirit levels mounted by means of the device supporting arm 38. The amount the spirit levels need to be adjusted by a cam, to bring the bubble between the central markings is shown on rotatable scales 60, 73 which control the cams. |
