Abstract of the Disclosure In the inspection of generally round glass con- tainers where the containers are indexed into the gauging stations or positions by the movement of a starwheel mech- anism, the containers are held in a generally upright at- titude with their bottoms engaging a pair of spaced rollers extending through a slide plate at the gauging station. Each roller is biased in an upward direction against the container bottom. The containers are rotated, in station, by engagement of the sidewall thereof by a rotating wheel mounted on an axis that is somewhat out-of-vertical to aid in holding the container down against the rollers and slide plate. The gauging rollers each have their vertical move- ments to drive the core of a separate differential trans- former. The output of the transformers are amplified, algebraically summed and fed to a discriminator. The track- ing of the rollers is such that the output signals from the discriminator are a reflection of the relative positions of the rollers and the output is fed to a reject mechanism or indicator when a predetermined difference indicates that a "leaner" container is being gauged.
