Elongate brake members are located under certain of the rollers of an inclined roller type conveyor and are raised by weighted levers into frictional braking engagement with those certain rollers to brake an item moving down the conveyor and over the rollers. The brake members are pivotally supported intermediate their ends so as to apply an equal braking force to the overlying rollers. The levers are rocked by actuators under control of item sensing members located at loading and unloading stations situated adjacent opposite ends of the conveyor.
