RE 20 H.P. CHASSIS ROAD SPRINGS.

Would you kindly note that in dealing with the general arrangement of the 20 H.P. chassis, Mr. Royce has decided that the frame should be considered level when the car is carrying its normal load. The following table gives an idea of what the normal load is considered to be;-

Load. Two-seater. Four-seater.
Light. Driver only. Driver only.
Normal. Driver plus passenger and bag. Driver plus two passengers and bag.
Overload. Driver, plus two or more passengers and bag. Driver, plus three or more passengers and bag.

Would you therefore please instruct the springing of the car to be arranged in this way.

E.{Mr Elliott - Chief Engineer}
