ABSTRACT:
A brake is provided for twin wheel casters. A brake lever extends between the wheels and is depressed by a toe. This rocks a link through a toggle position and presses a sheet metal brake shoe of generally W-shape against the inner drum or surface of the wheel flange to lock the wheel against rotation. Reverse movement of the lever is effected by a toe to unlock the brake. Edges of the sheet metal brake shoe impinge against the inner surface of the wheel flanges to lock the wheel, and locking action may be augmented by serrating the inner surface of the wheel.
