| X.39006 Alterations proposed for American R.R. Cars. -3- A/ 2nd. December, 1919. Contd. ventilator in the dashboard (6) A standardised Rolls-Royce Luggage carrier is most desirable, in view of the many poor designs of carrier used on our cars. The Fleetwood design, of which sketches were send to Mr. Barrington on June 24th, is thought to be a good type. The luggage carrier could be made outside the factory in lots of say 100, andfitted as a standard extra. (7) The Rolls-Royce coachbuilders' drawings show that the body should rest on the extreme rearward part of the chassis, but should not be bolted to it. In practice the frame members are invariably drilled in this portion by the coachbuilder and the body bolted down. The bodymakers say that if this is not done the overhung weight of the petrol tank etc. causes the rear of the frame to "flap" against the bottom of the body, Should we not provide holes in this position and instruct bolting? X.29001 Top pivot of rear spring shackle. This often suffers from rapid wear due to insufficient lubrication. We think that, the load being a great part of the time downwards on the pivot, the grease or heavy oil used does not have much chance to get between the surfaces in contact. The upper side of the pin is often found worn down about ".030" and rusted over the worn part. The shackle is found worn on each of the side faces, and the bush bell-mouthed. The grease cup on the shackle is often obstructed by the body so as to be difficult to reach. We would suggest bushing the upper part of the shackle in the same way as suggested for the spring eyes in Report B. The large end faces of Sketch the bushes would be an advantage for taking side thrust, the increased length of the bearing would help to take the rocking effect due to the side thrust and torsion of the spring. The oil plug, which would be similar to that used on the brake equalizershaft, would be very accessible. The hollow shaft Contd. | ||
