  • Tire inspecting apparatus
    Patent number: 4116055
    Abstract: Apparatus for automatically inspecting and moving tires through an inspection system. The tire is placed in a pan of sand and is rotated by a device grasping the bead of the tire so that the tire becomes embedded in the sand in order to stabilize its position. A covering hood, with an attached mirror, is aligned upon lowering with the aid of conical centering guides. After the tire has been inspected and removed, a rotary shovel smooths the sand so that the pan is ready to accept another tire for inspection.
