Abstract
Abstract A funnel-shaped admitting hopper for material to be separated communicates with a tubular conduit which is swingably mounted so that its outlet, remote from the admitting hopper, can be placed into registry with one of two openings for discharging into them metallic and non-metallic matter, respectively. A metal detector is located proximal to the conduit for detecting metallic matter as the same passes through the conduit. Biasing means normally urges the conduit to a position where its outlet communicates with the opening into which non-metallic matter is to be discharged. An actuating device is associated with the conduit and is responsive to detection of the metal by the metal detector, whereupon it deflects the conduit so that the outlet thereof registers with the opening into which metallic matter is to be discharged. On deactivation of the actuating means the biasing means returns the conduit to its normal position.
