Abstract
A plurality of rollers are carried by a support and have friction wheels fixedly secured, the wheels being frictionally engaged by further friction wheels which are slidably and non-rotatably carried on an input drive shaft. Biasing springs on the shaft urge the wheels into engagement with the wheels and the bias of the springs is adjustable by collars on the shaft to selectively vary the torque transmitted from the shaft to the rollers.
