Abstract
Glass bottle inspection apparatus including optical neck finish defect detector and mechanism for rotating the container or bottle to facilitate checking of the finish throughout its circumference. Gripping and rotation of the bottle or container is accomplished by a mechanism, adapted to any symmetrical shape, including non-round shapes, which comprises a resilient ring which is lowered vertically over the neck of the bottle or container to be checked when the bottle or container arrives at the test location of the apparatus. The resilient ring is engaged by a non-resilient annular ring which is in turn driven for rotational movement of the assembly. The elevating and lowering mechanism for the annular gripping ring also includes a downwardly biased bearing and flange member to urge the bottle out of engagement with the ring as the ring is raised, following checking.
