Dept. RE BONNET CATCH SPRINGS. 12.1.15. E2/G12115. I have noticed on Mr. Royce's car that it is difficult to open the bonnet, owing to the increased amount of friction produced by the bonnet catch springs, and as this will be rather a variable factor without some specification of loading, we would like to know the results obtained by making the following experiment. Introduce a clip as shewn in the sketch (sketch of a bonnet clip) CLIP W? of 1/32" thick material between the spring and the bonnet, and find what load the spring will sustain at the point of just breaking contact with the bonnet. This should be done for both. Stamp: RECEIVED JAN 12 1915 This sheet must be filed with the correspondence to which it refers. | ||
