  • Patent number: 4748877
    Abstract: A supply apparatus for supplying a screw, a rivet, or the like includes a chute in which one edge portion of an upper opening of a guide slit formed therein is located inside a stock section or thereabove, so that screws in an abnormal position can be removed by a brush member not on the upper surface of an oscillating dipper but on the upper surface of the chute. A timing between oscillation of the dipper and movement of the brush member need not be controlled. Screws of abnormal position can be removed with a simple mechanism so as to supply only those of normal position to a predetermined position, and to reliably return removed screws of abnormal position into the stock section.
