Abstract:  
This invention relates to machines for shot-peening workpieces, and more particularly to machines for subjecting workpieces to stress-peening processes. The term "stress-peening" refers to the operation of shot-peening a part while it is statically stressed in the same direction as the stress which is to be sustained when the part is in service. Still more specifically, the present invention relates to machines for stress-peening workpieces of the leaf spring type such as are currently employed in automotive vehicle suspension systems.
