An automatic bottle handling machine comprises a storage hopper for bottles in random orientation, a plurality of conveyor channels having conveyors extending between the hopper and a corresponding plurality of drop chutes and selective reversing devices for turning around neck first bottles before reaching the drop chutes. A sensor in each drop chute detects the prolonged presence of a bottle therein to stop the corresponding conveyor. A yoke member below each sensor indefinitely arrests the downward movement of an incorrectly oriented bottle or a defective bottle having a spur or flash on the bottom thereof to stop traffic in the corresponding drop chute and thereby stop the supply of bottles by the corresponding conveyor until the offending bottle has been removed by the operator. Another sensor for detecting a crushed bottle may be provided at the upper end of each drop chute for similarly stopping the corresponding conveyor.
