Abstract: Apparatus is disclosed which provides an entrance gating structure for spacing the entry of containers carried by a conveyor into a testing device. The containers arrive at the testing device under line pressure and are then permitted to enter a testing apparatus where they are conveyed through the testing device and then returned to the conveyor. The gating device is a spring-loaded pivot arm having a pair of legs. One leg stops the flow of containers until the prior container clears the length of the long or other leg. The gate functions automatically without requiring any external operator.

Abstract: Apparatus for testing glass containers for structural defects which may occur in the sidewalls thereof and which may render the containers incapable of withstanding a normal handling through a filling line and packing where the containers will be subjected to abuse. The apparatus is particularly designed to handle non-round bottles or containers and essentially takes the form of a pair of vertically oriented, rotatable, bottle-engaging rollers which, upon engagement with opposite sides of the bottle, will move the bottle through the gap between the two rollers. One of the rollers is laterally movable and biased toward the other roller, which has its axis fixed. An adjustable pneumatic pillow having a controllable pressure is positioned to be used to bias the mounting for the movable roller. The movable roller and its mounting structure has limited movement about a vertical pivot that is non-coincident with the vertical axis of the roller.
