ABSTRACT:
An article transfer arrangement includes a loading station and a discharge station spaced therefrom and level therewith, upper and lower pairs of parallel track rails extending between the stations, a rigid article carrier having an upper article engaging surface and front and rear wheels, the front wheels being closer to the article engaging carrier surface than the rear wheels, and an endless drive chain connected to the carrier and to a drive motor and operable to reciprocate the carrier between the stations. During motion between the loading station and the discharge station, the front wheels are lifted into engagement with the upper track rails by action of the drive chain about a chain sprocket whereby the carrier surface is oriented horizontally and is raised above the platform level of the station to thereby lift an article from the loading station. At the discharge station, the front wheels are lowered in a similar manner from the upper track thereby lowering the carrier surface out of contact with the article and depositing same at the discharge station. The carrier is returned to the loading station with the carrier surface lowered, thereby clearing the carrier beneath an article at the loading station awaiting transfer.
