TWIFLEX
A set of weighted lined shoes are carried by flexible cylindrical blocks in a central hub, permitting appreciable deflection under load, thereby imparting the low torsional stiffness characteristic which is an important feature of this design.
Compression springs disposed radially under each shoe provide adjustable restraint to give control of the engaging speed (at which the shoes move into contact with the drum).
