A spring is connected between a fixed point and one end of the cross of the T. The other end of the cross is connected to a fixed point and the upright of the T to one end of a damper the other end of which is connected to a fixed point. The arrangement is such as to provide for constant belt tension for considerable variations in belt length without mechanical adjustment.
