  • Patent number: 4301641
    Abstract: An article transfer apparatus (10) is provided for transferring articles (16) from a predetermined first position to a varying second position and discharging the articles (16) at the second position. Difficulty is often encountered in controlling the drop height of articles (16) delivered by a conveyor (18) for random placement at varying levels in a container (12). It is desirable to minimize the drop height to prevent damage to the article (16). A carriage (36) on the article transfer apparatus (10) is controllably operated to controllably discharge articles (16) at a preselected distance above either the bottom of the container (12) or articles (16) predisposed within the container (12). The invention is particularly useful for transferring finished metal piston pins (16) from a conveyor (18) to a tote box (12).
