Abstract
A revolving flexible circular steel band mounted on a drum, with a tightening member locking the band to the drum to transmit rotary motion of the band to the drum. The inner wall of the band is divided into three shoes which grip the drum when the band is tightened. The tightening member is an overlapping wedge which is depressed onto an underlapping wedge, with the resulting wedging action decreasing the circumference of the band and locking it to the drum.
