| - 27 - increases the resistance of the spring to torsion when the brakes are applied. This is the simplest expedient and is that adopted by R-R.{Sir Henry Royce} Other methods incorporate some sort of torque arm or radius rod to hold the axle rigidly in torsion. One has been patented by Mr. Royce on the lines of the attached sketch. Another for the use with semi elliptic springs, has been brought out by Beardmores. Torque arms have also been supplied to quarter elliptic springs as is indicated by the sketch of the Wolsley front spring, an extra top leaf fitted to which restrains the twisting of the front axle. contd.
