Abstract
A roller assembly for mounting carriages to rails is provided with a clamp having a pair of jaws securable to the rail by a handwheel. The length of bearing of the jaws on the rail is relatively small so that, upon loading a clamped assembly in a direction tending to move it along the rail, the clamp will rotate into tighter biting engagement with the rail to prevent slippage thereon. Release is achieved, even after the biting action, by positive separation of the jaws in response to loosening rotation of the handwheel with screw thread action driving the jaws apart from each other and from the rail.
