Abstract

346,509. Turning; screwing. HERBERT, SIR A., Dunley Manor, near Whitchurch, Hampshire, and LLOYD, A. H., Langwm, Warwick Avenue, Coventry. Feb. 12, 1930, No. 4733. [Class 83 (iii).] Lathes ; steady rests.-A turning lathe, particularly for turning and screwing stay bars for boilers, has a turning-tool and a screwing-tool mounted on the same saddle for simultaneous operation on the same bar, the two tools being adapted to rotate relatively to one another about the work. The saddle 3 which mav be fed bv a lead-screw or other means carries a base 7 having a vertical web 6 provided with a bush for steadying the work which is fed through the chuck 5. The base also carries a turning-tool 9, a parting-tool 10, and a selfopening die 8 driven from a longitudinal shaft 16 through a gear train 17. The parting-tool may be controlled by a lever 11 and the turning-tool is operated at the required times by means of a vertical cam rod 12 and adjustable tappets 14, mounted on a bar 15 acting in the manner described in Specification 226,622, [Class 83 (iii), Metals, cutting]. By this arrangement of tools both the screwing and the carriage feeds may be suitable for the work to be performed. In one example the work rotates at 1000 r.p.m. and a turning feed of 44 cuts to the inch is imparted to the saddle. If 11 threads per inch are to be cut the screwing die is rotated at 750 r.p.m. thus giving a net screw cutting speed of 250 r.p.m. and producing the required 11 threads per inch on the work. A sleeve 19 is adapted to engage the work and to be operated by a lever 20 to withdraw the work after it has been parted. The machine may if desired be arranged for entirely automatic operation.
