Bottle feeding machinery

A device for connecting the outlet of a first handling machine, having a delivery star wheel, and in which a series of objects are adapted to be delivered to an inlet star wheel of a second handling machine, said device comprising first and second parallel classifying worms disposed at some distance from one another and partially overlapping one another, one of said worms adjoining said outlet of the first machine and the other of said worms adjoining said inlet of the second machine, and a conveyor belt provided between said classifying worms for supporting and advancing said series of objects, a disengageable synchronous coupling disposed between said machines and said classifying worms, said second machine with the inlet coupled thereto having a separate creep-speed drive, means for positively displacing said first classifying worm transversely to its longitudinal direction so that said first classifying worm is positively displaced to an inoperative position away from contact with said objects so as to permit the accumulation of said series of objects should a disturbance, such as an interruption, occur at said second handling machine, and in the area of said first classifying worm, a guide rail is disposed along said conveyor belt for guiding said series of objects and preventing said series of objects from being pushed off said conveyor belt.
