ABSTRACT:
A flight lug assembly (5) for use on an article transport conveyor (50) is disclosed. The flight lug assembly includes a fill block (7) removably mounted on a flight lug (8), the flight lug being attached to the conveyor chain (35) of the article transport conveyor. The fill block is releasably locked on the flight lug by a spring clip (30) formed as a part of the flight lug, and having a normally biased position extending into engagement with a shoulder (20a, 20b) formed as a part of an elongate groove (19a, 19b) defined in the side surfaces (15, 16) of the fill block, and being in communication with at least a portion of an elongate flight lug slot (18a, 18b), respectively, defined in the respective side surfaces of the fill block, in which the flight lug is received. The second end (33) of the spring clip can be moved yieldably toward the side surface (29) of the flight lug, and will be yieldably held against the side surface of the flight lug within the flight lug slot as the flight lug is passed within either one of the flight lug slots for positioning the fill block on the flight lug, or removing the fill block from the flight lug once the spring clip is unlocked.
