  • Patent number: 4601384
    Abstract: This disclosure relates to an apparatus for feeding can bodies serially. The apparatus includes a delivery path wherein can bodies arranged in a row are presented one at a time to a feed apparatus wherein a rotating cam member receives the leading can body or similar cylindrical object and moves the same from the feed path to a delivery path. Several different types of feed mechanisms are illustrated, and most particularly there is provided an arcuate guide path which is concentric to a shaft carrying the cam member with the cam member being particularly configurated for cooperation with the arcuate path. The cam member will preferably have a partially spiral-shaped part. In a preferred embodiment, the delivery path stops immediately adjacent the cam member and there is a stop member against which the can is held by a cylindrical surface of the cam member. The can is moved endwise away from the stop out of the delivery path.
