Abstract: A gravity roller conveyor includes at spaced intervals special braking rollers which have stationary brake drum attachments adjacent to one of their ends. A pair of brake shoes, located within each of the brake drums, is pivotally mounted to and rotatable with each braking roller. Each pair of shoes is interconnected by springs urging the shoes away from the cylindrical braking surface of the drum. As the speed of the conveyor rollers increases under a moving load, the centrifugal force acting upon the brake shoes propels them outwardly against the urging of their springs and into engagement with the braking surface of the drum in order to retard the speed of the associated braking roller and, therefore, the load upon the conveyor.
