Abstract
A hub provided at an end of a roller rotates with the roller. A stationary cap mounted to an axle of the roller is positioned adjacent the hub. A pawl pivots on the cap and is movable to engage gears on the hub. The pawl has two abutment surfaces mounted. The pawl pivots between a first position wherein one of the abutment surfaces engages the geared surface to prevent rotation of the hub in a first direction and a second position wherein the other abutment surfaces engages the geared surface to prevent rotation of the hub in a second direction.
