My invention relates to the manufacture of swaged and tempered articles, and the principal object of my invention is to provide new and improved process for the manufacture of such articles. In the drawings accompanying this specification and forming a part thereof I have shown, for purposes of illustration, one form which my invention may assume, and inasmuch as my invention is particularly effective for the manufacture of machinists hammer heads, I have selected for illustration herein an embodiment of my invention peculiarly adapted for that purpose. |
