An article accumulation conveyor in which the drive for moving the articles is automatically discontinued for a selected section of the conveyor when an article is stopped on another section of the conveyor and is started again automatically when the article moves. The power for activating the starting and stopping instrumentalities is furnished in its entirety by the conveyor drive so that all need for extraneous power sources or forces exerted by a moving article is entirely eliminated. The activating power is transmitted by a "screw-jack" type of device so that enormous force can be furnished to the article carrying rollers which makes it possible to carry both small and large, light or heavy articles on the same conveyor at the same time.
