Abstract
A method of processing articles through successive operations requiring access to their top and sides comprises placing each article on a platform of a conveyor carrier, supporting the carrier on a carrier track positioned below the platform, and propelling the carrier through the processing operations by providing the carrier with a driving dog which is engageable by a pusher member of a driven endless chain located below the carrier, and which is disengageable from the pusher for the stopping and accumulation of carriers, as desired. Engagement between supporting wheels and guide rollers of carrier trolleys and the carrier track maintains the platform in proper position. Each carrier includes a driving trolley connected to at least one load carrying trolley by a tow bar located above the carrier track. The driving trolley is provided with a one-piece driving member having a holdback dog and a driving dog which includes a forwardly projecting cam formed with an abutment notch. A stop plate is engageable by the cam and notch to disengage the driving dog from a pusher and stop the carrier.
