| To R from DA. {Bernard Day - Chassis Design} Copy to EH. Copy to BI. Copy to CK. {Mr Clark} X.2628.b. -L (2) DA {Bernard Day - Chassis Design} 2/CB2-3-20. X.2628. ROAD SPRINGS. X.3950 X.1295 Replying to Mr Elliott's memo E2/G17220 X.1149 the proposal to use solid eyes on the rear springs X.1232 was first put forward in your note RB {R. Bowen} /P24-3-14. At this time a new shackle for the front end of the rear spring with its anchor bracket was under consideration, and you sent along a design in which the solid eye was used, the reason given being that it greatly improved and lightened the shackle. This improved shackle with the solid eye necessitated by it, was embodied in the thick leaf springs, and these thick leaf springs, subsequently split, were included in the general instruction for the after-the-war-chassis given in EH2/LG19-9-17. This is the history of how the solid eyes on the rear springs came to be used. X.3950 We send a print of "N" Scheme 261 in which we suggest in Fig I how the existing shackle could be used with the rolled eye spring, but we expect that this arrangement of eye will be thought to be somewhat difficult to make. On Fig II we shew the more conventional type with a longer shackle, for use in future, if thought desirable. Contd. | ||
