In the course of some correspondence I have had on the above subject with the Dunlop Co., it has just been brought home to me that it is not the Dunlop Co. who were responsible for the fitting of the retaining rings in the detachable nuts, but ourselves. It appears that originally the Dunlop Co. supplied the wire wheels with the detachable nuts in position and the retaining rings fitted, but owing to a complaint made by ourselves in regard to the scratching of the nut during transit, it was apparently arranged that the nuts and retaining rings should be sent separate from the wheels, and that the parts should be fitted together at these Works. This being so it is evident that we have got to take more care in assuring ourselves that the retaining ring is actually properly in position on the nut after the lock has been fitted into the wheel. This is unquestionably a difficult matter, but I feel pretty certain, (a fact I also impressed upon the Dunlop Co.) that in the two or three instances we have had where the detachable nut came out when attempting to remove a wheel, that the real cause of the trouble was that the retaining ring had never been properly fitted into its slot.
