A transport mechanism for articles between a pair of conveyors includes a constantly driven drive member, a driven member and a ball and detent mechanism intercooperating between a pair of confronting surfaces of the members. The transport mechanism is mechanically phased in and out in operation in timed relation to movement of the conveyor to which articles are moved. Mechanical phasing in and out is carried out by a lever having a tooth adapted for engagement in a notch of the driven member and a wheel cooperative with a rail including a gate on the drive member. The transport mechanism is phased out of operation when the wheel enters the gate and phased in in operation when the wheel exits the gate.
