Abstract
An apparatus for feeding electric circuit elements has a hopper for accommodating a supply of such elements, a capture tube or pipe extending substantially vertically through a bore in the bottom of the hopper which is movable relative to the tube in the direction of the axis of the latter so that the electric circuit elements in the hopper are captured one at a time by the tube and fed therethrough to a predetermined position at the outside of the hopper, and a separating plate disposed above the opening of the tube in the hopper for shielding the electric circuit elements under the separating plate from at least part of the weight of the electric circuit elements thereabove whereby the hopper can be provided with a large vertical dimension for accommodating a correspondingly large supply of the electric circuit elements without the danger that elements near the bottom of the hopper will be damaged by reason of the relative movement of the capture tube under the weight of the superposed circuit elements. Jamming or bridging of the electrical circuit elements above or around the opening to the capture tube is avoided by providing the bottom of the hopper with a conically concave in…
