Abstract
401,946. Forging socketed screws &c. HOLO-KROME SCREW CORPORATION, 80, Pliny Street, Hartford, Connecticut, U.S.A.-(Assignees of Purtell, W. A.; 687, Broadview Terrace, Hartford, Connecticut, U.S.A.) March 21, 1933, No. 8524. Convention date, March 28, 1932. Addition to 393,414. [Class 83 (iv).] Forging-dies and punches.-The process of forming socketed screws &c. described in the parent Specification by cold punching a socket in an unheated blank is modified by forming in the blank a uniformly tapered portion to be socketed enabling the screw &c. to be brought to its finished exterior shape by the cold punching operation in the die. A cylindrical blank is supported in the conical cavity 9 in the lower die 6 and is brought to the bulged form 2 by the action of the upper tools 14, 16 and pointed ejector 8 ; by a second operation in the same lower die 6 but using a different top die 20 the blank is brought to the form 3 with conical periphery 10, crowned top 21 and it may be partly socketed by a punch 22, the socketing being completed as shown in Fig. 4 by dies 31, 25 and punch 33. Headed screws are formed in similar manner.
