MANY chassis are equipped with clutches of the dry-plate type, and in some of these difficulty is experienced in arresting the spinning member, owing to no clutch stop being provided or the one in use acting
inefficiently. The saine trouble sometimes occurs with multiple-disc clutches working in oil, particularly when, the oil is cold.
In one chassis, a 2-ton Maudslay, a simple form of clutch stop which has proved very efficient has been fitted. This consists of two pieces of fiat steel bolted or riveted together and with their ends cut to suit the angle between the clutch shaft and the clutch-withdrawal arm, the ends being formed into a half-moon shape to fit the aforementioned parts. That at the clutch-shaft end can be lined with leather or Ferodo riveted to the plates, whilst the upper end is bolted to
the withdrawal arm. • If made of suitable dimensions and positioned correctly the device acts in such a manner that each time the clutch is thrown out to engage first gear the brake is pressed into contact with the clutch shaft and, by arresting this, enables the gear to be engaged silently.
In other makes and types of chassis it is often quite a simple matter to fit a split ring working against, say, a plate bracketed to the gearbox or supported by a cross-shaft, either the split ring or the plate carrying some good friction material.
