Herewith are N.Sch's 4634 and 4635 which show respectively the upper triangle lever and the main lever, with their bosses reinforced to deal with the fractures that have occurred on the bumping rig and on the road. In each case, the area of section to pure tension at the point of fracture has been increased 50% and the strength in bending rather more than 100%. The modification in each case can be effected on the existing dies. Da.{Bernard Day - Chassis Design} | ||
