<p>An apparatus for feeding record cards to and from a utilization station in a record card utilization machine comprises a support housing for a card origination hopper and a card collection hopper, which is mounted below the origination hopper. A transfer carriage is mounted for reciprocal, pivoted movement from a first position where it receives a card from the origination hopper, to a second position at the utilization station where the card is utilized, and back to the same first position where it returns the card to the collection hopper. A card feeding and returning mechanism is associated with the hoppers to feed cards to and remove cards from the carriage at different times in the sequence of operation of the apparatus, but nevetheless with the carriage at the same first position in its path of reciprocal, pivoted travel. An operation aligning a card received on the carriage in the utilization station, performed by coaction of the card with an alignment platform, also sets up the card for receipt by the feeding and returning mechanism for return to the collection hopper. A transverse carriage and card aligning operation is performed by interaction of a cam, mounted at the utilization station, and a cam follower, mounted on the carriage, when the carriage is pivoted to its second position.</p> |
