Abstract

764,912. Diamond tools. CORONEL, H. S. Oct. 11, 1954 [Nov. 10, 1953], No. 31039/53. Class 124 A method of cold setting a diamond in a holder comprises maintaining the diamond in position by the application of pressure to a powder surrounding the diamond. As shown, a diamond A is placed in a square hole J in one end of a cap B having a screw thread at its other end. A powder G, e.g. sand or a powdered metal, is then poured into the cap to surround and cover the diamond and a concave disc C placed over the powder. A shank E is then screwed into the cap to apply pressure to the powder and hold the diamond in position. A washer D may be placed between the disc C and the shank to prevent the powder entering the threads and a lock-nut F may be used to prevent slackening of the cap.
