We send herewith N. sch. 2416. shewing the proposed 5" universal joint for use on EAC.10. It is intended to follow the practice of the Mechanic's joint almost entirely, and the middle view is arranged to do that. In case however the sliding arrangements are not entirely approved of we have shewn the upper view with a sliding device similar to the present Spicer joints. We think the middle view is the one to proceed with until further instructions. We also shew on fig. 3. an alternative construction for eliminating the apparent quarrelling between the bearing blocks and the joint rings. R.{Sir Henry Royce} has not finally said whether he likes this, though he has seen it, therefore we think this alternative should not be proceeded with for the moment. We have arranged for the joint to give a clear movement of 15º on either side, which we believe is about twice as much as it is ever asked for. This joint is shewn mounted on EAC.10. gearbox, and the hypoid axle, but we wish to try the joint on EAC.1. first. We have therefore shewn on N. sch. 2536. (herewith) an adaptation for EAC.1. by making a special joint member for the front end. DA.{Bernard Day - Chassis Design} [STAMP: REC'D MAR 14 1928 HS{Lord Ernest Hives - Chair}] | ||
