Abstract
When the tube of a feeder assembly for a glass forming machine is lowered into engagement with the spout bowl, the separation of the jack and the tube support lifts a ring assembly which normally rests on the jack housing. This exposes a pressurized air conduit resulting in a sensed pressure drop which confirms that the tube has engaged the spout bowl.
