Abstract
824,067. Screw-cutting; punching. FABRIQUE J. A. CHAPPUIS S.A. Sept. 16, 1957 [Oct. 17, 1956], No. 29116/57. Classes 83 (3) and 83 (4). In a press (not shown), means for cutting screw-threads comprises a tap &c. spindle 22, Fig. 3, urged towards the die 2 of the press by a resilient member, e.g. the spring 25, and rotated by a gear train 5-8, 11 (Fig. 2, not shown), on the punch holder 1 of the press, a toothed rack 12, secured at 13 to the die 2 and meshing with gear 11, rotating the spindle 22 upon movement of the holder 1 towards the die. For producing from strip metal a flange with two tapped lugs, at least one punch, shaping tools, forming tools (not shown), and at least one tapping spindle 22 are mounted on the holder 1. Alternatively, the spindle 22 may carry a die for cutting external threads. As depicted, the holder carries a pair of spindles 22, 27, each having driving flats 23 engaged by a sprocket-sleeve 21 driven by a chain 15 engaging a sprocket 10 on shaft 9 of gear 8. Thus, the spindles 22, 27 rotated by feeding the holder 1, need not advance at the same rate as the holder, the springs 25 permitting different rates of feed. The gears 5-8, 11 are mounted in an interchangeable box 4 on the head 1, which is guided on posts 3, and it is stated that threads of different pitches may be cut simultaneously by the spindles.
