Roller conveyor

In a roller conveyor which includes a shaft, a roller rotatably mounted on said shaft and a frame which carries said shaft, the improvement comprising a side member which forms a part of said frame, the upper portion of said member being turned to form a loop, a vertically elongated opening in said member, said opening being of a size sufficient to receive the end of said shaft through the upper part of the opening and to permit downward movement of said shaft into the lower part of said opening, the edge of said upper portion being inward of the extreme end of the shaft, the upper part of said opening being above said edge and the lower part of said opening being below said edge, said upper portion of said member being resilient whereby when said end of the shaft is received into the upper part of said opening and moved downwardly said upper portion of said member will yield to permit said end of the shaft to pass by said edge and move into said lower part of said opening and then said edge will move back to a position overlying said shaft end to lock said shaft end against movement upwardly beyond said edge.
