Further to Hs{Lord Ernest Hives - Chair}' memo in connection with the above car, in which he makes certain recommendations in connection with steering, we find on looking into the road springs that the body actually fitted is practically 2 cwt. lighter than the weights given to us at the time the springs were specified. In addition, we have sprung for the usual complement of four passengers and 1 cwt of luggage. If it should happen that Mr.Summers drives habitually with only two passengers and no luggage or 1 cwt. in the rear compartment, it would mean that we could go even lighter still on the springs. In any case, we would reduce the springing of the car in view of the lighter body by 50 lbs. on each front spring and 100 lbs. on each rear. If less than four passengers are habitually carried, it would probably give up to 75 lbs. on each front and 150 on each rear, which, with a load in the form of a light body and few passengers, would make a very material difference to the springing. You would probably like to take up this question with the owner, to find out whether he carries less passengers than we reckoned for, before deciding on the springs. The springs in question would be, for either proposal:- a/- Dealing with reduced weight of body only. --------------------------------------- Front. Nearside. - 1050 Minus. Rear Nearside - 1700 Offside. - 1100 Minus. ---- Offside - 1800 b/- If it should happen that the customer tours with only two passengers and luggage, the springs to suit these would be:- Front. Nearside - 1000 plus Rear. Nearside - 1600 plus Offside - 1050 plus ---- Offside - 1700 plus. BY.{R.W. Bailey - Chief Engineer} | ||
