Abstract
A glass machine system in accordance with presently preferred embodiments of the invention includes a glassware manufacturing machine for manufacturing articles of glassware and transferring the articles to a linear conveyor, at least one linear chain conveyor for receiving and transporting such articles from the machine, and a speed sensor for monitoring linear speed of the conveyor. The speed sensor includes a magnetic energy source, a magnetic energy sensor and bracketry mounting the source and sensor adjacent to the conveyor. The chain conveyor teeth affect magnetic energy coupling between the source and sensor as the conveyor passes adjacent to the sensor. Electronic circuitry is responsive to signals from the sensor for determining linear speed of the conveyor and maintaining a constant linear speed at the conveyor.
