| ORIGINAL To By.{R.W. Bailey - Chief Engineer} from Da.{Bernard Day - Chassis Design} Da{Bernard Day - Chassis Design}8/M25.5.22. c. to Gj. c. to Wex. c. to Hs.{Lord Ernest Hives - Chair} ✓ 6 GOSHAWK - REAR SHACKLE OF REAR SPRING. Y4261 We send herewith N.sch. 1289 showing a stop for preventing the axle pushing back in the event of the rear spring breaking. You will see that it consists of teeth formed solid with the shackle forging, and with the stationary pin in the rear cross member. It is proposed to allow the shackle to go back 8° and an angle of 7° forward will allow the spring to practically come into line with the shackle. Except for this stop it is not intended to alter the shackle from the arrangement sent you on N. scheme 1282. Da.{Bernard Day - Chassis Design} | ||
