We send herewith LeC.5421 showing the design of a petrol filler tilted at 20o from the vertical, which is applicable to the Bentley II in particular, but may be used if desired on the Phantom III and 25 H.P. cars having outside fillers. A design was desired by the Expl. Dept. in order to make up and fit to a car one of these fillers for the Sales Dept. and other interested parties to view. The cap is intended to be exactly the same as now except that it is of thinner section and for the experiment an existing cap can be turned down. The weight of the present cap appears rather exaggerated. The body casting containing the hinge lugs can be turned from an existing casting which has had its interior lightening grooves left out. The chamfered aluminium sleeve surrounding the filler snout is supplied long and this is filed by the Coachbuilder to suit the contour of the body. The sheet metal ring and rubber grummet are also bent by the Coachbuilder to conform with the body panel shape. As we propose to paint the aluminium sleeve and the sheet metal ring the latter can be in mild steel instead of Staybrite steel as at present. We have shown a gun rack which will pass the French gun and at the same time hold the old fashioned Bowser pump nozzle. If, however, a gun rack is not required it may be left off. We suggest that this is a matter for experiment. Likewise we would be glad if tests could be made to discover whether the inner separating tube could be dispensed with. Examining the possibility of filling with a can by drawing board methods, we are rather forced to the conclusion that this tilted filler offers little or no benefits over the vertical one because if the filling from the can is attempted directly, the wing and the filler cap make it impossible to reach the mouth of the filler with the mouth of the can until the latter is partially emptied, in other words petrol is spilt. | ||
