X.8110 X.5110 X.4590 In connection with the trouble we are periodically encountering in the shape of leaky glands on the water pump, or glands which are too easily over-tightened, I had the idea we might try out cork, and I am handing you herewith a number of glands made up in different ways, in which cork is used in each case as a basis. I would like you to fit glands of this type to engines which are on the dynamometer, in the first place, and if they show signs of being reasonably good, we might then fit them to certain chassis. The matter is a pure experiment, as I have no experience to work upon, but knowing that cork makes a good friction clutch surface, and secondly that it is very elastic it xx occurred to me that it might XX fill the duties of a gland satisfactorily | ||
