Abstract: An endless conveyor having two adjacent, aligned, parallel chain loops each having two rectilinear portions. Between the loops and entrained by friction are suspended carrier members for carrying objects along the two rectilinear conveying tracks defined by the chains. A latching device comprising a spring-loaded, U-shaped member which wedges between spaced chain links thereby preventing sliding of the carrier members at the loop ends is provided to allow passage from one track to the other.
