Abstract

251,501. Tennant, W. J., (Lockwood, L. V.). Aug. 20, 1925. Blowing; forming screw-necked bottles. - Relates to mechanism for forming a screw thread in the mouth of a parison as it is being formed in a bottle-blowing machine. The mechanism is shown applied to a rotary-table turnover machine in which each blank mould 3 has associated with it a mandrel E having a threaded tip. The shank 10 of the mandrel is threaded and works through a nut 5 carried by the mould. Thus by turning the shank 10, the mandrel may be screwed into or out of the ring mould 3<a>. In accordance with the present invention, the lower end of each mandrel shank 10 is formed with a pinion or collar E<1> which has its underside provided with clutch lugs 25. These lugs are adapted to engage a clutch member F<1> which is carried at the upper end of a rod 12. The rod is raised or lowered by a pneumatic cylinder 28, and it is rotated by a shaft 17 through the medium of gear wheels 15. In operation, a shaft 12 is raised by a cylinder 28, and the rotation of the shaft screws the mandrel 12 into the ring mould. After the mould is charged with metal it is carried by the rotation of the machine to another station where the mandrel is screwed out of the ring mould by another mechanism similar to that shown, thus leaving the mouth of the parison formed with an internal screw. The unscrewing of the mandrel is started, however, while the mould is travelling between the two stations by a toothed segment which engages the pinion El.
