ABSTRACT:
A flight which is attached to a drive mechanism such as a chain is disclosed. The flight may be used to form a conveyor for transporting articles, when a series of flights are attached to the drive mechanism in succession. The disclosed flight includes a horizontal slot in its forward support element which is slipped onto a pin on the drive mechanism, and a rear support element having a vertical slot with a detent, which is snapped onto a succeeding pin as the flight is rotated downward around the forward support pin in the horizontal slot of the forward support element, acting as a pivot. Attachment and detachment is very simple, requiring no special tools. The forward and rear support elements are in different vertical zones or planes, so that the forward support element of one flight may be attached to the same pin as the rear support element of an adjacent flight. This allows the flight to be used with double pitch as well as single pitch chains. Because of the horizontal slot in the forward support element and the overlapping of the forward and rear support elements on a single pin, the flight does not tend to pop off when experiencing stresses in its working environment.
