| P/. FROM DA.{Bernard Day - Chassis Design} C. to S/. HS.{Lord Ernest Hives - Chair} ORIGINAL DA{Bernard Day - Chassis Design}2/M1.9.31. 25HP. BATTERY SUSPENSION - 'U' SERIES. X6055 We send herewith N. sch. 3333. shewing a modifica- tion to the cantilever battery suspension shewn on N. sch. 3278. It will be seen that the cantilever is supported half way along its length by a pressing running axially with the chassis, so assisting in preventing the twisting of the frame side member shaking the battery. We have shewn a pressing for the longitudinal member. We are not sure whether there is a cheaper way of making this, for instance, it would be possible to make it of parallel channel. If you have any preference would you please inform us. DA.{Bernard Day - Chassis Design} | ||
