Abstract
A weight actuated dispensing mechanism including a bracket adapted to be attached to a conveyor system and having an inlet opening therein for receiving material from the conveyor system, and an outlet opening for allowing the material to exit from the bracket by gravity. A valving mechanism is pivotally attached along an axis to the bracket for movement between a first position wherein the valve mechanism closes the outlet opening of the bracket and a second position wherein the valve mechanism is open to allow material to pass from the conveyor system, through the bracket, to a container disposed below the bracket. A projection on the valve mechanism is provided for automatically increasing the closing force on the valve mechanism as it closes. One end of a flexible line is attached to the valve mechanism and extends over the projection. The other end of the line is attached to the container for holding the container, whereby a predetermined amount of material by weight is automatically dispensed into the container, upon which event the valve mechanism automatically closes to insure that no more than the desired weight of material is dispensed.
