Abstract
320,798. Nixon, C. R. Nov. 14, 1928. Blowing.-In an automatic machine for blowing bottles, jars, and like hollow glass articles, a parison is not shaped by a single mould, as usual, but is formed in two moulds one of which receives a charge of glass and shapes it into a blank while the other forms the blank into a parison. The machine comprises a non-rotary frame 10, Fig. 2, which carries two sets of mould units and is mounted on castors 11 so that it can be moved up to a feeder. The opening and closing of the moulds, and the movements of the blowheads and transfer devices, are effected by means of pneumatic cylinders, and the supply of air to the cylinders is controlled by valves 23 operated in proper sequence by cams 22 secured to a shaft 21. The shaft is driven by an electric motor through two friction discs 15, 17 and a worm 19. A parison is formed in an inverted position, and it is transferred from the parison mould to the finishing mould by means of the ring mould which swings in a vertical plane and deposits the parison in an upright position in the finishing mould. A charge of glass from a feeder is received in a mould 71, Figs. 2 and 3, consisting of two halves which are pivoted on a pin 68 and are opened and closed by a cam plate 73 that is moved vertically by a pneumatic cylinder 81. As soon as the charge has entered the mould, a blowhead 98 descends and covers the opening in the mould, and compressed air is admitted through the blowhead to force the glass into a compact mass into the mould and into the ring mould 55. The blow head is moved vertically by a pneumatic cylinder 94, Fig. 2, and is swung horizontally by a cam 108. After the glass is settled, the blowbead lifts, the mould 71 opens, and the glass blank is immediately enclosed by the parison mould 87. This mould consists of two halves hinged on a pin 85 and opened and closed by a pneumatic cylinder 91. The mould has the bottom closed, as shown in Fig. 9, and is provided with inset portions 87<1> at the bottom to restrict' the parison at this point in order that the bottom of the finished bottle may not be unduly thickened. The blank is blown up in this mould by air admitted through the neck-forming mandrel 133 to a chamber 132 within the ring- mould. When the mould 87 opens, the parison is supported by the ring mould 55 and is transferred by it to the finishing-mould. The ring mould consists of two halves hinged to a bracket 52, Fig. 3, which projects laterally from a gear wheel 50. This wheel is pivoted on a stub shaft 49, Figs. 3 and 6, carried by an arm 44 which is slotted at its lower end, and the slot 43 embraces a pivot pin 42. The wheel 50 engages a double rack 51, oi the shape shown, and a pin 45 on the arm 44 engages a cam slot 46 parallel with the rack. The arm 44 is oscillated about the pin 42 by a pneumatic cylinder 63, and when it is' moved from right to left in Fig. 6, the rotation of the wheel 50 reverses the ring mould, and the parison is inverted and carried over into a position where it is enclosed by the finishing-mould 115. After the mould has closed on the parison, the ring mould is opened by a trip 163 and is restored to its original position. A blowhead 125, Fig. 3, is swung down on to the finishing mould by a pneumatic cylinder 128, and air is supplied through the blowhead to form the parison into the finished article.
