Sch. 4253, showing the Wilmot Breedon type stabiliser bumper made suitable for Bentley. The length is increased as compared with the Rover Pilot bumper, so as to span the overall width of the Bentley tyres. Also the end weights have been modified to render them more securely fixed. In the Rover type, pulling up the lower nut which holds the bumper bar and weights to the spring, the two lock nuts holding the weight appear to be unloaded, and as they cannot in the first case be very effectively locked the weights are loosened. We have made the stud holding the weights to their casing larger than the stud holding the bumper and weights to the spring, and have effectively locked the weight-holding nut. We have also provided a large steel washer to press against the lead weights. We have endeavoured to provide a maximum of lead weight in the available casing. We should like Messrs. Wilmot-Breedon to make the bumpers with these modifications to the ends, but the remaining pieces, with the exception of the flanged inner bush for the silent-bloc, which you already have, are intended to be Wilmot-Breedon pieces. We do not expect to have saved any weight. Da.{Bernard Day - Chassis Design} | ||
