Abstract
A pneumatic elevator for containers is provided wherein a vertical duct has end portions with nozzles in the form of holes extending through the ends and entering the duct in a downstream direction. The sides of the duct are provided with guide rails and at least one side is provided with a plurality of apertures along the length thereof through which air, introduced into the duct through the end nozzles, is exhausted. The size and angle of the nozzles are correlated with the static pressure differences across the jets to provide the requisite duct static pressure with respect to the size and number of apertures in the inner side which determines the volume of air exhausting from the can duct. Differential static air pressure separates each can from the other to minimize scratching and denting. The lower end of the elevator may be provided with an in-feeder to feed cans into the elevator from storage or from an accumulator and the upper end of the elevator may exhaust into a deaccelerator which slows down the cans coming from the elevator and positions them at the proper speed and spacing for the subsequent work station.
