  • Patent number: 4129188
    Abstract: An impact device for use in machines, such as presses, for marking, punching, stamping, forming, riveting, and other related operations, wherein a convex edged member, such as a ball, axially separates a tool and a hammer, the hammer being loaded by compressible means such as a tension spring, all moveable axially within a moveable spindle. The ball is displaced radially into an adjoining magazine at the point of full extension of the spindle, after the tool is in contact with the workpiece, thereby allowing the spring loaded hammer to strike the tool, imparting an impact force to the workpiece.
