Plural article transfer mechanisms are operated in timed sequence by an electronic control synchronized to a main drive shaft. Each article transfer mechanism transfers articles from a dead plate to a moving conveyor. An extensible-retractable pusher arm engages, moves and releases the articles between 90 DEG positions under control of a fluid motor mounted on a turntable. Operation of the fluid motor is based on rotary alignment of a pair of turntable ports with a pair of fluid supply channels in a turntable drive body. The turntable is stepped in rotary increments between 90 DEG positions by an electric stepping motor. The angular speed profile of the pusher arm between the 90 DEG positions is governed by a programmed electronic control, including a PROM, which drives the stepping motor. An adjustable finger clip assembly is snap-fitted on the pusher arm and provided with a handle for ease of replacement.
