Abstract
Abstract A LAPPED STREAM OF ARTICLES TRANSPORTED ALONG A WIRE BELT CONVEYOR SYSTEM IS INTERRUPTED AND DIVERTED THROUGH A CONVEYOR GAP NORMALLY SPANNED BY A PIVOTABLE BRIDGING CONVEYOR SECTION. A STREAM INTERRUPTING FINGER ASSEMBLY IS MOMENTARILY DRIVEN INTO THE STREAM AHEAD OF THE BRIDGING SECTION WHILE THE UPSTREAM END OF THE LATTER IS PIVOTED ACROSS THE STREAM PATH TO OPEN THE CONVEYOR GAP. BOTH THE FINGER ASSEMBLY AND BRIDGING SECTION ARE DRIVEN BY A COMMON LINKAGE POWERED BY THE CONVEYOR THROUGH A SINGLE REVOLUTION CLUTCH. ALTERNATE OPERATIONS REVERSE THE BRIDGE MOVEMENT TO RESTORE THE STREAM TO ITS ORIGINAL PATH OF TRAVEL.
