Abstract
617,597. Making nuts. TRIPP, C. D. June 8, 1945, No. 14603. Convention date, July 28, 1944. [Classes 83 (ii) and 83 (iv)] [Also in Group XXV] Forging-machines ; dies.-Nut blanks with locking tongues 26, Fig. 4, have these tongues bent, to cause the threads on them to be distorted from the pitch of the main thread of the nut, axially radially and by varying the helix angle. The deformation is effected by a die 33, Fig. 6, having a threaded shank to screw into a ram, a flange 55 with opposed flats, and a concentric annular part 57 formed with one or more inwardly and axially extending crests 58 by grinding surfaces 59 to an angle of about 10 degrees to a horizontal plane passing through the crests. A modified form of nut blank is produced in a forging- machine to the shape shown in Fig. 9. In subsequent stages the lugs 62 are bent or rolled over to the position shown in dotted lines in Fig. 11. A combined reamer and tap is then entered into the blank from the face 67 to tap both the main body and the edges of the lugs. Finally the lugs are further bent to the position shown in full lines to distort the thread from the true lead position as described above. Specification 1649/03, [Class 89], and U.S.A. Specifications 2,320,785, and 2,352,668 are referred to. The Specification as open to inspection under Sect. 91 describes a press in which the nut 28, Fig. 13 (Cancelled), is supported on a bed 35 and the die is brought down by an eccentric operating a yoke (not shown) connected to the ram cylinder 37 sliding in guides 38 in the frame. The cylinder contains liquid above the piston 43 and a port 45 admits air above the liquid from a supply at 51 through a non- return valve 48 controlling the minimum pressure, a loaded exhaust valve 49 determining the maximum pressure. A predetermined maximum pressure is thus applied to the nut independently of the stroke of the press. This subject-matter does not appear in the Specification as accepted.
