Feeding and orienting device

An apparatus having a guide means and adapted for feeding and orienting parts, each of said parts having a body which may be described in orientation relative to a line of travel along said guide means by a major reference axis and a minor reference axis perpendicular to and intersecting said major reference axis, such that said body is properly oriented when conditions are met that said major reference axis is tangent to a point of said line of travel and said minor reference axis is in a required angular orientation about said line of travel at said point and said body is misoriented when said conditions are not met, comprising:

• a first ejection means adjacent to said guide means for ejecting parts that are misoriented in one way, with said major reference axis yawed relative to said line of travel, by causing transverse displacement of said parts relative to said guide means, whereby said parts misoriented in one way are caused to become unbalanced and to fall from said guide means;
• a second ejection means adjacent to said guide means, for ejecting parts that are otherwise misoriented, with said major reference axis pitched or said minor reference axis rolled out of said required orientation relative to said line of travel, said second ejection means located to emit fluid onto said otherwise misoriented parts to blow them from said guide means and not to blow properly oriented parts from said guide means.
