Abstract:  
An improved shot peening machine is of the type which includes blast wheels capable of propelling a plurality of shot generally downwardly into a critical blast region of the machine for shot peening a plurality of springs passing there through. The improvement includes a housing for the machine including a blast cabinet, an entrance chamber and an exit chamber. The blast cabinet generally defines the critical blast region. Horizontally extending spinner rolls for the springs extend through the blast cabinet and terminate at a first end at a first edge of the critical blast region within the entrance chamber and a second end at a second edge of the critical blast region within the exit chamber. The springs are conveyed along a peening path on the spinner rolls from the first end to the second end thereof. A feeding system feeds the springs from an exterior of the housing into the entrance chamber to supply the springs to the first end of the spinner rolls. A discharge system discharges the springs from the exit chamber to the exterior of the housing as the springs are conveyed from the second end of the spinner rolls.
