Abstract:  
This invention relates to multiple leaf springs and has particular reference to springs adapted for use in automotive vehicles although it is applicable to leaf springs for other types of vehicles and uses. It has for its main object the provision of a spring made up of leaves which, in comparison with the leaves of springs as heretofore made, will have a materially greater load-carrying capacity and a longer useful life.
