Abstract

Bracket (1) containing a gear train holds the end of spring (19) wound in a direction to be opened when the bracket moves up from the paper tray (7). Spring (19) is wound on an arbor (15) which is mounted on a shaft (9) which is located on the pivot axis of the bracket. Spring (17) is wound on a second part of the arbor in a direction to be closed when the bracket moves away from the tray. Spring (19) has a much tighter grip on the arbor than spring (17). In operation the bracket resists upward movement under the influence of stiff paper being fed, and is slowed in its downward movement to reduce bounce, which increases the speed at which a second sheet can be fed.
