| -2- R.R. 256. (5 H.{Arthur M. Hanbury - Head Complaints}) (X.X. 753. 9/5/13.) Bx. 7201979. COMPLAINT. Re J.{Mr Johnson W.M.} L. Clark (Contd). 1913 June 9th Mr. Wormald is asked for the makers report on the defective springs returned from customer. June 17th. He replies that the makers report that they cannot trace any flaw in the springs returned to them. They have referred to their books and find that they have not supplied any of these springs for some years, so that it is impossible to state the exact tempers these springs were made. They say it is extremely difficult to trace the exact mixture of the steel, and other points after such a long period, and they regret they cannot give any satisfactory explanation of the breakages. Mr. Wormald states that he is of opinion that the steel was imperfectly heat treated. June 17th. Customer encloses W another broken spring and states that these breakages have caused him considerable trouble, and he asks them to forward a set of springs which they know to be really up to the work required of them. June 18th. Copy of above letter is sent to Mr. Wormald, and instructions are issued for 6 inlet valve springs to be forwarded. Mr. Wormald reports that he is still of opinion that the steel of these springs was defective. He states they are sending new springs of a slightly thinner section as the steel will not be quite so highly stressed. These springs will not in any way affect the power of the engine at any ordinary speeds. The new springs should be charged to R.D.D. and instructions are given accordingly. W communicate with customer as per Mr. Wormald's memo above. June 23rd. Customer informs W that he will try the new springs on reaching home. He presumes that they will be of different tension and so cannot be used with the old ones. He states that the car runs very well and with more power than before, and is quite satisfactory but for the breakage of the springs. June 24th. W acknowledge above letter and copy is sent to Mr. Wormald. He replies that there is no objection to running both strengths of springs on the engine at the same time. June 25th. W inform customer that the springs have not yet been despatched, as they are unfortunately out of stock, but same shall be forwarded immediately they receive a further consignment from the makers. They inform customer that there is no objection to running both strengths of springs at the same time. July 1st. Springs despatched. | ||
