Phantom III. Ring file Petrol Filler on Side of Body. For a long while we have been investigating the problem of designing a practically universal petrol filler for mounting on the side of the coachwork, no matter what the shape of the rear of the body may be. Several previous attempts at this have been made on the Bentley with a measure of success, the main criticism being the lack of universal application. On LeC 4777 herewith we show a design of petrol filler which we believe to be completely universal in its application to Phantom III. This drawing shows it mounted on an enclosed limousine, but a subsequent scheme in hand will show how the same parts without alteration will go on a continental touring limousine. A steel plate 1/16ths.inch thick is provided by the Coachbuilder in the body at the locality at which he proposes to place the filler head. Into a hole in this he welds the piece of steel tubing supplied by ourselves, and in the position given on our scheme with respect to its height above the steel panel. It will be noticed that the filler head can then be introduced into this tube from the outside and set into position necessary rotationally to enable the hinge and cap to appear horizontal no matter what the slope of the panel may be. This position being obtained the Coachbuilder files a slot in the edge of the welded in tube to locate the filler head by means of the pin provided in the filler head. The next procedure is to introduce the top elbow into into the filler head from inside and to hold it in lightly by means of the ring nut. This elbow may be revolved until it assumes a suitable position. The two ends of the filler tube can then be brought together at the rubber joint, the lower tube being cut to length by the Coachbuilder. After the rubber joint is in position the ring nut in the filler head can be tightened up when the inner elbow and top Syphon tube will automatically take up the required position. It will be noticed that we have introduced the gun rack scheme used on our previous Bentley design, and also an anti-blowback float. | ||
