Bailey - Chief Engineer} X4197 Hs{Lord Ernest Hives - Chair}7/LG8.8.21. R-R MECHANICAL TYRE PUMP. There are several points in connection with the R.R. Tyre Pump in which designs are not completed:- 1. Non-return & vent for crankcase. 2. Hand-operated toggle arrangement in place of control on the Dash. 3. Oil Filter in pipe line. 4. Pipe line and fittings for frame. We occasionally get demands for tyre pumps and we think it would be an excellent thing if the R-R Tyre Pump was completed so that we should have something to offer to customers. We also recommend that, if possible, a sheetmetal guard should be fitted over the exposed gears. In the position the gears are in, they collect all the dust which comes from the radiator and which, in the summer-time, is very considerable. Hs.{Lord Ernest Hives - Chair} | ||
