A guard for enclosing the sprocket, trolley and chain elements of a conveyor at a sprocket wheel turn, comprises a circular cover portion having a diameter greater than that of the sprocket and a skirt extending generally perpendicularly from the entire circumferential edge of the cover portion. Portions of the skirt are severable therefrom at locations defined by the ends of the arc of the turn at which the guard is mounted to provide passages for the conveyor chain through the skirt and into engagement with the sprocket. |
